The accuracy of language is vital in academic writing. If your essay is
full of careless errors, it would not only annoy your readers, but also
impede their understanding of the writing. No matter how well the text is
organized or how creative your ideas may be, the essay might not receive a
high grade if there are numerous language errors. The frequent occurrence
of errors in language use may,for one thing, indicate the writer’s
carelessness or hasty writing; for another, and worse, it reveals the writer’s
poor foundation of English.
So you need to comply with rules of punctuation and the conventions
of grammar, as well as use appropriate vocabulary when drafting your
essay. After you have finished your drafts, i.e. in the post-writing stage, the
final proofreading can also help you avoid some language errors.
Generally speaking, we can define language accuracy in terms of
grammatical and lexical accuracy. To achieve grammatical accuracy, you
should obey a specific set of grammar rules that deal with parts of speech,
number, person, tense, and punctuation. Lexical accuracy is related to the
use of words, which mainly refers to the correct spelling, appropriate word
choice and collocation.In the following sections, we will analyze several
types of grammatical and lexical errors that are commonly made by most
students. To ensure language accuracy, you must avoid: run-on
sentences,agreement errors, errors in the use of articles, dangling modifiers
and word choice errors.
7.1 Avoiding run-on sentences
A run-on sentence is a sentence that contains two or more independent
clauses without the proper punctuation or conjunction. An independent
clause has both a subject and a verb and can stand on its own as a complete
sentence. It is acceptable to join several independent clauses in one
compound sentence by using certain punctuation marks, such as semi-colon
(;) and colon (:), or using conjunctions like and, but. However, if you fail to
follow punctuation rules, a sentence can become a run-on sentence. For
example:
- A wise man makes his own decisions an ignorant man follows
public opinion.
- The results of the study were inconclusive, more research needs to
be done on the topic.
Example 1 is actually made up of two independent clauses — a wise
man makes his own decisions and an ignorant man follows public opinion.
But there is no punctuation between the two clauses, or say, these two
clauses fuse together. This type of run-on sentences is called fused
sentences. Lacking the punctuation here may result in ambiguity and make
the reader confused, not knowing what the writer wants to express.
In Example 2, a comma (,) is used to separate two independent clauses
— the results of the study were inconclusive and more research needs to be
done on the topic. However, the position of this comma is too weak to make
a complete relationship between two complete sentences. It is also a
grammatical error to only use a comma to connect two independent clauses.
When two independent clauses are connected by only a comma, they
constitute a run-on sentence that is called a commasplice.
Academic writing requires grammatical accuracy for the work to be
taken seriously. Therefore,it is important for writers to eliminate run-on
sentences in order to convey a professional and formal tone. In fact, there
are five commonly used ways to fix run-on sentences.
First, use a full stop (.) to split the run-on sentence into two or more
smaller sentences. It is the easiest way to fix a run-on sentence. This
revision works especially well with longer sentences. For the fused
sentences, add a full stop between the two independent clauses and
capitalize the first letter of the following clause. For instance, Example 1
can be fixed as: A wise man makes his own decisions. An ignorant man
follows public opinion. The meaning of the resulting sentences becomes
clearer compared with the original run-on sentence. For the comma-splices,
replace the comma with a full stop and capitalize the first letter of the
following clause.
Second, use a semicolon (;) to separate the independent clauses in a
run-on sentence. Inserting a semicolon between independent clauses creates
a grammatically correct sentence. Using a semicolon is a stylistic choice
that establishes a close link between the two sentences / clauses. For the
fused sentences, add a semicolon; for the comma-splices, replace the
comma with a semicolon. Take Example 1 for instance. It can be improved
as: A wise man makes his own decisions; an ignorant man follows public
opinion. The semicolon used here indicates a strong relationship between
these two independent clauses.
Third, use a coordinating conjunction (e.g. and, but, for, yet, nor, so,
or) with or without a comma. This method emphasizes the relationship
between the two clauses and forms a compound sentence. In particular, for
the fused sentences, add a comma and a coordinating conjunction; for the
comma-splices, keep the comma and add a coordinating conjunction. For
instance, the two clauses in Example 2 is not in parallel with each other;
instead, the first clause expresses a reason for the second clause. Thus, it
requires the coordinating conjunction so to indicate the relationship
between them. By using a comma paired with a coordinating conjunction,
we can improve it as: The results of the study were inconclusive, so more
research needs to be done on the topic. Similarly, Example 1 can be fixed
as: A wise man makes his own decisions, but an ignorant man follows
public opinion.As a result, the meaning of the whole sentence and the
relationship between these two clauses becomes quite clear.
Fourth, use a semicolon and an adverbial conjunction (e.g. therefore,
however, meanwhile,besides, in addition). This method is similar to the
third one: emphasizing the relationship between the two clauses and
forming a compound sentence. The difference lies in the type of
punctuation and conjunction being used. A minor difference is that after the
adverbial conjunction, it often needs to add a comma to separate the
conjunction from the following clause (See Section 4.1.2 for more
examples of adverbial conjunctions and the construction of compound
sentences). By adopting this way, Example 1 can be revised as: A wise man
makes his own decisions; however, an ignorant man follows public opinion.
Since a wise man contrasts with an ignorant man, we can use the adverbial
conjunction however to indicate such relationship and place a semicolon
before the conjunction.Similarly, Example 2 can be improved as: The
results of the study were inconclusive; therefore,more research needs to be
done on the topic.
Finally, use a subordinating conjunction (e.g. after, although, before,
unless, as, because) to turn one of the independent clauses into a dependent
clause. The comma can be used or not according to the subordinating
conjunction being added. This method also emphasizes the relationship
between the two clauses, but it constitutes a complex sentence. Take
Example 1 for instance. Since a wise man and an ignorant man form a
contrast, we can use the subordinating conjunctions that indicate a
contrasting relationship, such as while or whereas. A comma is needed in
this case. Thus, we can improve Example 1 as: While / Whereas a wise man
makes his own decisions, an ignorant man follows public opinion.
In general, you should avoid packing many independent clauses into a
single sentence. Through careful proofreading, you would be able to
identify the run-on sentences in your essay and then choose any of the five
methods mentioned above to revise them. Notice that a run-on sentence
could be transformed into several simple sentences, a compound sentence
or a complex sentence.Your choice of the appropriate fix for run-on
sentences should take the diversity of your sentence structures into
consideration. For example, if you are in need of more complicated
sentences in your essay, turn a run-on sentence into a complex sentence by
using the proper subordinating conjunction.

7.2 Avoiding agreement errors
There are two major types of agreement errors: one is subject-verb
agreement errors and the other is pronoun-antecedent agreement errors. We
will examine the errors in subject-verb agreement first, because many
students are inclined to make this type of grammatical errors.
7.2.1 Subject-verb agreement errors
As we mentioned in Section 4.2.1, a simple sentence contains one
subject and one verb, and may(but not must) have a complement. The
subject tells who or what (the actor); the verb tells the action or the state of
being; the complement completes the meaning of the verb or adds more
information to the sentence. There is a grammatical rule requiring that in
any sentence, the subject and the verb need to agree in number, which is
known as singular or plural. Two simplified formulas can be used to
describe the subject-verb agreement:
➢ Singular Subject + Singular Verb = Agreement
➢ Plural Subject + Plural Verb = Agreement
For example, the book is…, books are…, the robot moves…, robots
move…, etc. Because the subjects the book and the robot are singular in
number, the corresponding verbs should also be singular in number (is and
moves). Similarly, to “agree” with the plural nouns books and robots, the
verbs should be plural in number (are and move). Notice that we all refer to
the third person singular or plural in this section.
A subject-verb agreement error occurs when the subject and the verb
of a sentence do not agree in number. There are four major types of
situations in which agreement errors take place:
(1) when it is tricky to determine whether the subject is singular or
plural;
(2) when the subject is heavily modified (it would be difficult to
identify the head noun / real subject);
(3) in adjective clauses;
(4) in inverted sentences.
So how to fix these agreement errors? There are several rules to
follow, and some of them require practice so that you will become familiar
with them.
Determining the number of the subject
First, due to the irregularity of many English plural subjects, it is
sometimes confusing for students to determine its correct number. The
regular plural subjects has an “s” added at the end of its singular form. But
some nouns take irregular plural forms, such as man (singular) — men
(plural),person (singular) — people (plural), mouse (singular) — mice
(plural), tooth (singular) — teeth(plural), deer (singular) — deer (plural),
sheep (singular) — sheep (plural), etc. In the plural forms of these nouns,
there is no “s” at the end. So you need to think twice before writing the
correspondent verb of these subjects, realizing that even though some
subjects do not have “s” at the end of them,they could still be plural
subjects, which require plural verbs. For instance:
Incorrect: The decayed teeth needs to be dealt with in time.
(Agreement error: teeth — plural;needs — singular)
Correct: The decayed teeth need to be dealt with in time.
Some sentences have compound subjects, which consist of more than
one subject, with different parts joined by conjunctions like and, or, but, or
connectives with, together with, as well as, except,etc. Compound subjects
may cause difficulties in the subject-verb agreement, as it is complicated to
determine the number of compound subjects. Usually, the compound
subjects connected by and are considered plural; they would need to be
matched with plural verbs. For example:
Incorrect: Microsoft, Starbucks and Boeing hires technical graduates
from Edmonds Community College. (Agreement error: Microsoft,
Starbucks and Boeing — plural;hires — singular)
Correct: Microsoft, Starbucks and Boeing hire technical graduates
from Edmonds Community College.
But notice that some compound subjects linked by and are in fact
referring to the same thing as a whole, which form a single unit (e.g.
peaches and cream, bread and butter). Such special compound subjects
therefore require single verbs.
For the compound subject connected by neither...nor, either...or, not
only...but also, or, nor,the verb should agree with whatever part of the
subject it is closest to in the sentence. For example:
Incorrect: Neither the president nor her assistant have replied to the
accusation. (Agreement error: her assistant — singular; have — plural)
Correct: Neither the president nor her assistant has replied to the
accusation.
In this example, Neither the president nor her assistant is a compound
subject with two parts the president and her assistant linked by neither…
nor. The part that is closest to the verb is her assistant, a singular noun
phrase. According to the rule, the verb in this sentence should be singular as
well, so has is the correct form.
For the compound subject joined by connectives like with, together
with, except, as well as,in addition to, the verb needs to agree with the noun
before the connective. For instance:
Incorrect: The driver together with his children are not injured in the
car accident. (Agreement error: the driver — singular; are — plural)
Correct: The driver together with his children is not injured in the car
accident.
In the compound subject of this example the driver together with his
children, the connective together with links two parts: the driver and his
children. The noun before the connective is the driver, which is singular in
number. In keeping with the rule, the verb has to agree with it in singular
form, so the correct verb form is is.
Besides the irregular plural subjects and compound subjects, the
subjects which are particular nouns or pronouns whose number is difficult
to determine also contribute to the agreement errors.One such particular
type of nouns is collective nouns, such as family, team, or staff. They refer
to a group of people, animals or things. Collective nouns can be either
singular or plural depending upon the rest of the sentence. Typically, they
take the singular form, as the collective noun is treated as a single unit. For
instance, His family enjoys going for a walk after dinner.
Indefinite pronouns which do not refer to any person or thing in
particular may sometimes cause difficulty for students to identify their
number. Generally, after the indefinite pronouns each, either,everyone,
everybody, anyone, anybody, neither, nobody and someone, you need to use
singular verb forms. For example:
● Anybody on the basketball team is eligible for the scholarship.
● Everything on the bed and everything in the closet was organized in
under an hour.
● Someone holds an entirely different point of view.
In addition, the proper name, i.e. a noun that denotes a particular thing,
such as a person’s name,a company’s name, a title of a book or an article
should be considered singular. As the following examples illustrate:
● Marvel Studios’ “Avengers: Infinity War” brings to the screen the
ultimate, deadliest showdown of all time.
● In many minds, Mercedes-Benz is the automotive status symbol,
offering desire-inducing vehicles with luxurious rides and interiors.
● The Old Man and the Sea is one of Hemingway’s most enduring
works.
Another type of particular noun is a gerund, which is formed from a
verb that refers to an action,process, or state, by adding -ing at the end of
that verb, for example, describing and thinking. The gerund or the gerund
phrase should be considered singular and matched with a singular verb. In
the examples below, the subjects are the gerund or gerund phrases;
therefore, the correspondent verbs(is and becomes) are singular in number.
● Jogging is one of the most effective exercises to lose weight.
● Enhancing people’s awareness of their health becomes necessary.
● Freeing up time and brains for us to tackle society’s most complex
problem is one of Artificial Intelligence’s advantages.
Identifying the real subject
The second situation that may cause subject-verb agreement errors is
when subjects consist of noun phrases that have different modifiers to
modify the head noun, i.e. the real subject or the most important word in the
subject. Therefore, due to the complexity of the subjects, it would be
difficult to identify the real subject, thus causing difficulties to determine
the right number that the verb should be matched with.
In a complicated subject, the adjective, the adjective phrase, the
prepositional phrase or the adjective clause are often used to modify the
head noun, as the following examples illustrate. In Example 1, the adjective
phrase covered in mud is used to modify the head noun dogs. In Example 2,
two prepositional phrases introduced by of and in are used to modify the
head noun pace. In Example 3, an adjective clause who score highly in this
type of behavior is used to modify the head noun people. Once the head
noun, or say the real subject of the sentence, is detected, we can easily
match the number of the verb with it.
- The dogs covered in mud seem to be injured.
- The pace of technological growth in Artificial Intelligence has made
workers both excited and anxious about what the future holds.
- People who score highly in this type of behavior are sensitive and
steady.
In the examples above, although the modifiers are all after the head
noun (so called postmodifiers), there could be sentences with both pre-
modifiers (i.e. the modifiers that are before the head noun) and post-
modifiers. In this kind of heavily modified subject, you need to identify the
real subject. For instance:
- Incorrect: Physical health problems like obesity continues to
become more serious.(Agreement error: problems — plural; continues —
singular)
Correct: Physical health problems like obesity continue to become
more serious.
- Incorrect: The declining number of new immigrants in recent
years have aroused the public attention. (Agreement error: number —
singular; have — plural)
Correct: The declining number of new immigrants in recent years
has aroused the public attention.
In the subject of the first example, the head noun should be problems,
with a pre-modifier physical health and a post-modifier like obesity.
Therefore the verb needs to correspond to the number of this real subject
(problems), which is plural. In the second example, the noun phrase in the
subject is complicated: there are pre-modifiers the + declining and post-
modifiers of new immigrants + in recent years. So the head noun is number,
which is singular and thus requires the correspondent verb to be singular as
well.
One more structure of the subject that calls for attention is the one of
structure. Because the real subject in this pattern should be one (which is
singular), but not the noun or the noun phrase after the preposition of
(which is usually plural), the verb needs to be matched with the real subject
in the singular form. For instance:
Incorrect: One of the studies find that the boys at three are rated as
more active than the girls of the same age. (Agreement error: one —
singular; find — plural)
Correct: One of the studies finds that the boys at three are rated as
more active than the girls of the same age.
In adjective clauses
As we have mentioned, the adjective clause may serve as a type of
modifiers that are used to describe the noun phrase in a sentence, therefore
causing difficulty in identifying the real subject. In fact, the adjective clause
itself is usually the source of subject-verb agreement errors, if the verb in
the adjective clause doesn’t match the noun it is referring to. Generally
speaking, adjective clauses follow two patterns:
➢ Relative Pronoun (who, which or that) as Subject + Verb
➢ Relative Pronoun (whose, whom) or Adverb (when, where or
why) + Subject + Verb
In the first pattern, the verbs in the adjective clauses should agree with
the antecedents of who,which or that, which might be the subject or the
object of the entire sentence. In the example below,the relative pronoun
who actually refers to the subject of the sentence children (which is
plural),while the verb in the adjective clause (gives) is singular, causing a
subject-verb agreement error. The correct version matches the verb with the
plural subject.
Incorrect: The children who gives in to temptation early on will be
more likely to be lonely,easily frustrated and inflexible when they grow up.
(Agreement error: children —plural; gives — singular)
Correct: The children who give in to temptation early on will be
more likely to be lonely,easily frustrated and inflexible when they grow up.
Similarly, when the adjective clause is modifying the object of a
sentence, the verb in the clause should also agree with the antecedent of the
relative pronoun (the object of the sentence),as illustrated in the following
examples. Try to figure out what the relative pronoun refers to and identify
its number. In Example 1, the relative pronoun that refers to an environment
(singular), and thus the verb should also be singular (is). Pay attention to
Example 2, where the phrase precedes the relative pronoun who is Indiana
University. But Indiana University is not a person, so it should not be the
person who refers to. This relative pronoun actually refers to an associate
professor(singular), and thus the verb in the adjective clause need to be
singular as well.
- Teamwork not only increases efficiency but also creates an
environment that is suitable for mutual learning.
- Karl MacDorman is an associate professor at Indiana University
who specializes in humancomputer interaction.
In the second pattern, there is a subject and a verb in the adjective
clause. So, in this type of adjective clause, the subject and the verb within
the clause should agree with each other in number.As in the first example
below, the adjective clause why reviews is such an integral part of
education is used to modify the noun reason (also the object of the
sentence). This adjective clause contains a subject (reviews) and a verb (is).
It is an agreement error that the subject and the verb do not match in
number here. So the correct way is to revise the singular verb (is) to be
plural (are). In the second example, after the relative adverb when there are
a subject the domestic oil price and a verb become.They need to agree in
number (both singular) in order to avoid the subject-verb agreement error.
- Incorrect: This is the reason why reviews is such an integral part
of education. (Agreement error: reviews — plural; is — singular)
Correct: This is the reason why reviews are such an integral part of
education.
- Incorrect: They are waiting for the time when the domestic oil
price become aligned with that of the world market. (Agreement error: oil
price — singular; become — plural)
Correct: They are waiting for the time when the domestic oil price
becomes aligned with that of the world market.
Inverted sentences
An inverted sentence is a sentence in which the normal order of a
subject followed by a verb is reversed, such as questions or there be
structure. Often, an inverted sentence begins with a word that needs
emphasis. With the order of the words changing in inverted sentences, it is
important for the subject to be accurately identified, and then the subject
and the verb agree in number, or else a subject-verb agreement error would
easily take place. For example:
- Incorrect: There was a doctor and a crew of nurses in the
emergency room during the surgery. (Agreement error: a doctor and a crew
of nurses — plural; was —singular)
Correct: There were a doctor and a crew of nurses in the emergency
room during the surgery.
- Incorrect: Only after understanding the situation do the teacher
make a comment.(Agreement error: the teacher — singular; do — plural)
Correct: Only after understanding the situation does the teacher make a
comment.
Example 1 is a there be structure in which the verb (be) precedes the
subject (a doctor and a crew of nurses), so it is easy to get confused,
especially when the subject starts with a singular noun a doctor. As we have
mentioned, the compound subjects connected by and are usually considered
plural. Therefore the verb should also be plural (using were instead of was)
for agreement.Example 2 illustrates the situation when an auxiliary verb do
is used to “help” the main verb in an inverted sentence. In this sentence, the
only-structure emphasizes how important something is in understanding a
situation clearly. The real subject of this sentence is the teacher (singular in
number), so the auxiliary verb do should be in its singular form does and
the main verb in its base form (make).
7.2.2 Pronoun-antecedent agreement errors
A pronoun is a word that is used instead of a noun or noun phrase,
often because the person or thing has been mentioned earlier in the sentence
or passage, for example he, they, it, hers, and them.An antecedent is the
noun or noun phrase the pronoun refers back to. Pronouns and their
antecedents must agree in number, person and gender. If any of these three
aspects are not matched, the pronounantecedent agreement error takes
place.
The agreement in number between the pronoun and its antecedent is
most tricky. You need to identify which antecedents are considered singular
and which are considered plural. As we have mentioned in Point 1 of
subject-verb agreement errors, there are several guidelines for determining
the number of nouns or noun phrases. We summarize some types of
singular and plural antecedents as follows.
Indefinite pronouns as antecedents
Singular indefinite pronoun antecedents include: each, either, neither,
one, no one, nobody,anyone, anybody, anything, everyone, everybody,
everything, someone, somebody. So the pronouns that have these singular
antecedents need to be singular as well, for example:
Incorrect: Each of the students should hand in their assignment at the
end of this month.(Agreement error: each — singular; their — plural)
Correct: Each of the students should hand in his / her assignment at
the end of this month.
Plural indefinite pronoun antecedents include: several, few, both,
many. Accordingly, the pronouns that match with these plural antecedents
must be plural, for example:
Incorrect: Both (of the brothers) had successful careers and his future
looked bright.(Agreement error: both — plural; his — singular)
Correct: Both (of the brothers) had successful careers and their future
looked bright.
Compound subjects / nouns as antecedents
Compound antecedents joined by and are considered plural, so the
correspondent pronouns should also be plural, for instance:
Incorrect: Tom and John are going to give his presentation at this
International Medicare Conference. (Agreement error: Tom and John —
plural; his — singular)
Correct: Tom and John are going to give their presentation at this
International Medicare Conference.
When the compound antecedents are connected by neither…nor,
either...or, not only...but also,or, nor, the pronoun should agree with the
nearest antecedent in number, for instance:
Incorrect: Either the son or the parents should be responsible for his
improper behavior.(Agreement error: the parents (the nearest antecedent) —
plural; his — singular)
Correct: Either the son or the parents should be responsible for their
improper behavior.
Collective nouns as antecedents
Collective nouns (e.g. group, audience, jury, crowd, team, etc.) may be
singular or plural,depending on their meaning in the sentence. If the
collective noun is acting as one unit, then the corresponding pronoun should
be singular. While if the collective noun emphasizes the individuals
constituting the unit, the pronoun has to be plural in number.
Correct: The jury should read its verdict. (The jury is referred to as a
whole.)
Correct: The jury (members) gave their individual opinions. (The
jury refers to all the members composing a whole.)
Pronouns and their antecedents should also agree in person. If the
antecedent is in the first person, the pronoun should be the first person; if
the antecedent is in the second person, the pronoun should be the second
person; if the antecedent is in the third person, the pronoun should be the
third person. As the following example illustrates:
Incorrect: If a person wants to succeed in corporate life, you have to
know the rules of the game. (Agreement error: a person — third person;
you — second person)
Correct: If a person wants to succeed in corporate life, he or she has
to know the rules of the game.
Correct: If you want to succeed in corporate life, you have to know
the rules of the game.(informal)
In this example, the antecedent a person is in the third person, so its
corresponding pronoun should also be the third person, instead of the
second person. Therefore, the solution for this agreement error is either to
change the person of the pronoun (as the third person) or to change the
person of the antecedent (as the second person). But as we have discussed,
the second person may not be regarded as formal enough for academic
writing; thus it is better to keep the third person singular antecedent a
person, and revise the pronoun to be the third person singular he or she.
In fact, this example also demonstrates the difficulty of pronoun-
antecedent agreement in gender. When the gender of the antecedent is
clearly specified, for example if the antecedent is John or Susie, you can
easily decide whether to use the pronoun he or she to match it. But when
the gender of the person is not mentioned, finding a pronoun that agrees
with its antecedent can be difficult. Antecedents like a person, a student, or
a doctor can refer to either a male or a female, so there is no justification for
only using the masculine pronoun he / his / him or the feminine pronoun
she / her / hers. One solution for such case is to use he or she or his or her to
match the antecedent whose gender is not clearly specified, for instance:
Incorrect: A teacher can make a profound impact on his students.
(Agreement error: a teacher —either masculine or feminine; his —
masculine)
Correct: A teacher can make a profound impact on his or her
students.
However, if you use the expression he or she or his or her too many
times in an essay, the effect can be ridiculous. Another solution is to
pluralize the antecedents, such as using teachers instead of a teacher, people
instead of a person; then you can use the pronoun they / their to agree with
the antecedents in gender as well as in number and person. Accordingly, we
may revise the previous two examples in the way below:
Correct: Teachers can make a profound impact on their students.
Correct: If people want to succeed in corporate life, they have to
know the rules of the game.Exercises

Whenever you are using a noun in your writing, you need to consider
the use of articles.In English grammar, an article is a kind of determiners
that can define a noun as specific or unspecific. For example, if you say
this is a book, you are referring to something (a book) that is general
or unspecific. But if you say this is the book I mentioned before, you are
referring to a specific book which you have talked about earlier. So, the
articles a and an are called indefinite articles , and the article the is a
definite article.
Studies show that a large number of grammatical errors in English
writing are related to article use. Since the correct usage of articles involves
many rules and exceptions, we only focus on those important rules in this
section. Most article misuse might have arisen from a misunderstanding of
how to treat countable and uncountable nouns. So first you need to
distinguish between countable and uncountable nouns. Countable nouns are
nouns that can be counted (e.g. students, trees, and ideas), and they have
both singular and plural forms (e.g. a student vs. students, a tree vs. trees,
an idea vs. ideas). While uncountable nouns are nouns that cannot be
counted (e.g., water, evidence,and research), and they are often treated as
singular without the plural form.
Rule 1: Use an article before the singular countable nouns.
Check the singular nouns that are countable in your writing: Whether
there is an article (e.g. a or the) or another determiner (e.g. each, my, this)
preceding it. If no, an error takes place. For example:
Incorrect: Idea can transform the world.
Correct: An idea can transform the world.
Correct: This idea can transform the world.
In this example, the countable noun idea is in its singular form. If there
is no determiner before it, a grammatical error takes place. The solution is
to add a suitable article (an or the, depending on the context) or a
determiner (e.g. this or that).
Now let’s consider when to use the indefinite articles a / an and when
to use the definite articles the. Generally, when you introduce a person or
thing for the first time or when you refer to it as a general type of person or
thing, use a / an. When you refer to a person or thing that has already been
mentioned or is going to be defined specifically afterwards, use the. Let’s
compare the following two pairs of examples.
[Pair 1]
- A journalist went to our office.
- The journalist went to our office.
[Pair 2]
- A journalist should be objective and tell the truth.
- The journalist who asked the question seemed hostile.
The first pair of examples illustrate the use of different articles when
you introduce a person for the first time and a person who has been
mentioned before. In Example 1, the journalist who went to our office is a
newly introduced person, so the indefinite article a should be used to
modify the noun journalist. In contrast, the journalist in Example 2 must
have been mentioned in the preceding sentences; then the definite article the
is suitable to modify the noun.
The second pair of examples demonstrate the different usage of articles
to refer to specific and unspecific persons. In Example 3, A journalist is
used to refer to any person who works as a journalist. The sentence equals
to: All journalists should be objective and tell the truth. So here the
indefinite article is used to refer to somebody general or unspecific.
However, in Example 4, the definite article the indicates this journalist is a
specific one and is depicted immediately afterwards(who asked the
question).
Rule 2: Do not use the article the before the plural countable nouns
unless they refer to the specific people or things.
Since the indefinite articles a / an are only suitable for the singular
countable nouns, the only difficulty of article use left for plural countable
nouns is the definite article the. If the plural countable nouns refer to people
or things in general, do not use the; but if they refer to some people or
things specific, the needs to be used. Look at the following examples.
● The plural countable nouns without articles:
- We need helpers of all types, such as engineers, scientists and
teachers.
- The pace of change has workers both excited and anxious about
what the future holds.
- This measure is in the long-term interest of schools and universities.
● The plural countable nouns with articles:
- She has published several books this year. The books are all
concerned about children’s right.
- The concepts of marine transgression and regression are considered
to be fundamental.
- A study has revealed that the teenagers who spend more time on
online social media feel less happy in almost every aspect of their lives.
In Examples 1-3, all the plural countable nouns do not have a definite
article preceding them because these nouns refer to the people in general
(e.g. engineers, scientists, or workers) or the things in general (e.g. schools
and universities). Whereas in Examples 4-6, the is used before the plural
countable nouns because these nouns refer to some specific things or
people. In Example 4,the first sentence mentions several books published
by a lady. Then in the second sentence, when these books are mentioned
again, a definite article needs to be used to specify the books. In Example 5,
the writer does not refer to all concepts but only the specific concepts about
marine transgression and regression. Similarly in Example 6, the writer
does not mean all teenagers feel less happy, but merely a particular group of
teenagers who spend more time on online social media feel less happy.
Rule 3: Do not use the article the before uncountable nouns unless they
refer to something specific.
Uncountable nouns usually include abstract or intangible things (e.g.
information, air), liquids(e.g. milk, wine), and things that are too large or
numerous to count (e.g. equipment, sand). A noun that is uncountable
cannot be made plural or used with a / an. You only need to consider
whether to add the definite article the before uncountable nouns. The rule is
similar to Rule 2: if the uncountable noun refers to something general, do
not use the; if the noun refers to something specific, use the. For example:
● The uncountable nouns without articles:
- Intelligence is one of the defining features of being human and it
comes in various forms.
- Dehydration can reduce motivation, increase fatigue and make
exercise feel much more difficult.
- They need to find information quickly and be able to summarize it
in clear language.
● The uncountable nouns with articles:
- Look at the information that precedes the paragraph in question.
- It is difficult to resist the temptation of easy profits.
- Environmentally-conscious Germans are worried about the
pollution (that) cars produce.
In Examples 1-3, those uncountable nouns refer to abstract things in
general and they have not been mentioned previously, so they do not need
to have the preceding them. By comparison, the uncountable nouns in
Examples 4-6 refer to the specific things. For instance, Example 4 does not
require you to look at all the information, but just the information that
comes before the paragraph which is being discussed. Example 5
emphasizes one type of temptation: the temptation to make easy profits.
The type of pollution mentioned in Example 6 is the pollution that is
produced by cars.Therefore, when an uncountable noun refers to something
specific, you have to use the definite article preceding it.
Rule 4: Articles go before adjectives.
When an article modifies a noun (either countable or uncountable) that
is already being modified by an adjective, the article goes before that
adjective. For example:
- A small-screen portable TV can be a wise investment.
- The approximate number of children in this school is 300.
In the first example, there are two countable nouns. The first noun TV
is being modified by the adjectives small-screen and portable. The
indefinite article a sits before the adjectives. Similarly,the second noun
investment is being modified by the adjective wise and a goes before the
adjective.In the second example, the definite article the goes before the
adjective approximate to modify the noun number.

7.4 Avoiding dangling modifiers
A modifier is a word, phrase, or clause that describes a word or makes
its meaning more specific.You need to identify the word that the modifier is
describing. Sometimes, when a modifier is a phrase, the sentence becomes
more complex, and the word that the modifier is intended to modify may
not exist. This results in grammatical errors called dangling modifiers or
hanging modifiers. In most cases, the dangling modifier appears at the
beginning of the sentence, for example:
- Having finished the assignment, the TV was turned on.
- Inside the space station, the Earth was illuminated by the Sun.
In Example 1, the present participle having finished the assignment
depicts an action, but it does not state who is the doer. According to English
grammar, the doer must be the first noun (also the subject) in the main
clause that follows. So this sentence implies the TV has finished the
assignment,which does not make sense. The real doer should be some
person who has finished the assignment,and then he or she turned on the
TV. In this sentence, having finished the assignment becomes a dangling
modifier, because the word it really modifies does not exist.
Similarly, in Example 2, it is illogical for the prepositional phrase
inside the space station to refer to the Earth. Since the word being modified
by this phrase has not been clearly stated, the prepositional phrase is
regarded as a dangling modifier.
So how to fix dangling modifiers? There are several solutions. The
most commonly used way is keeping the modifier, but restructuring the
main clause by adding the appropriate word being modified as the subject
of the clause. For instance, we can revise the previous two examples as:
Correct: Having finished the assignment, Anna turned on the TV.
Correct: Inside the space station, the scientists caught the view that
the Earth was illuminated by the Sun.
After revision, Anna becomes the logical doer of the action having
finished the assignment in Example 1 and it is in the correct position (i.e. as
the subject of the following main clause). In so doing, the modifier is not
dangling, but is next to the word it modifies. Example 2 is also revised in a
logical way: the prepositional phrase inside the space station modifies the
scientists. So it means that the scientists are in the space station and they
saw the spectacular view.
The second way to correct a dangling modifier is changing the
modifying phrase to a subordinate clause, clarifying the subject and verb in
this clause, while keeping the main clause.Take a look at the following two
examples.
Incorrect: Without knowing his name, it was difficult to introduce him.
Correct: Because Angela did not know his name, it was difficult to
introduce him.
Incorrect: After writing The Tempest, Shakespeare’s retirement from
playwriting came quickly.
Correct: After Shakespeare wrote The Tempest, his retirement from
playwriting came quickly.
In the first example, the prepositional phrase without knowing his
name becomes a dangling modifier because the subject of the following
main clause it cannot be a logical doer of the action “not knowing his
name”. Therefore, we may revise the sentence by changing the dangling
modifier to a subordinate clause that starts with because, and name the doer
of action (i.e. Angela) in the clause.In this way, the sentence becomes much
clearer.
At a first glance of the incorrect sentence in Example 2, it may seem
right because it was Shakespeare who wrote The Tempest. But a close
examination reveals that: Shakespeare’s name is in the possessive case
(Shakespeare’s), which means that grammatically Shakespeare’s is acting
like an adjective. The real noun / subject is retirement. Hence the sentence
is actually saying that Shakespeare’s retirement wrote The Tempest. This is
of course ridiculous. We can change the dangling modifier to a subordinate
clause which clarifies the doer of the action (writing The Tempest) as
Shakespeare. Accordingly, use a possessive pronoun his to replace
Shakespeare’s in the main clause to avoid repetition. The rest of the main
clause is kept the same without restructuring it.

7.5 Avoiding word choice errors
Word choice, also called diction, means the use of the best words for
getting your point across.If you use the inappropriate words, it can lead
directly to misunderstandings of the information.Therefore, to achieve
clarity for your essay, it is important to avoid word choice errors.
There are many types of word choice errors. First, writers may choose
a word that is pronounced like another word but has a different spelling or
meaning, for example write and right, some and sum. These words are
called homophones. If you mean to express an idea, but accidentally use a
homophone, the idea may be totally different from what you intended to
express. For instance:
- Incorrect: He wants to here the singer performing without any
distractions.
Correct: He wants to hear the singer performing without any
distractions.
- Incorrect: There will be a written examination to compliment the
practical test.
Correct: There will be a written examination to complement the
practical test.
In the first example, the writer mistakenly uses here, a homophone of
hear, and makes the meaning of the sentence difficult to interpret. In the
second example, compliment and complement are a pair of homophones
frequently misused by language learners. As a verb, compliment refers to
say something nice about someone or something, while complement means
to add something that enhances or completes. They convey totally different
meanings, so when they are misused in the second example, the sentence
would become problematic and hard to understand.
There are also some words which are spelled like each other, but they
mean different things or belong to distinct parts of speech, such as affect vs.
effect, choose vs. chose, later vs. latter. You need to distinguish these easily
confused words.
Secondly, word choice errors may take place when users are not clear
about the context in which a word is usually used. When you are using
synonyms (i.e. words with similar meanings), you need to think about what
the differences are between these words. For example, in the following
sentence, the writer uses the adjective exciting to describe the smell of
coffee. Although exciting has the meaning of causing excitement in one’s
emotion, it is not suitable to describe a smell (which is a sense). However,
its synonym stimulating can refer to activating a part of a person’s body or
senses.So stimulating is more suitable to be used in this context.
Incorrect: The exciting smell of freshly-brewed coffee can get one’s
blood pumping when waking up.
Correct: The stimulating smell of freshly-brewed coffee can get
one’s blood pumping when waking up.
For another example, we can distinguish between the synonyms
youthful and juvenile. The word youthful has the positive connotation
relating to both childhood and vitality. Meanwhile, juvenile may technically
mean the same thing, but it also has the negative connotation relating to
immaturity.If a company is advertising a health and beauty product, the
advertisement would probably state it gives you a youthful appearance, but
not a juvenile appearance, because the latter would simply imply that one
looks childish.
The last type involves the use of ambiguous words (see Chapter 4).
Strictly speaking, it may not be regarded as an error, but it can be
considered as an ineffective or inappropriate choice of words.For example,
some vague words such as good or stuff, are in fact not specific enough to
effectively deliver your message. A poor sentence like This essay is good
could mean any feature of the essay — e.g. it is well organized; it is clear
and logical; it contains no or few language errors; etc.So whenever possible,
use descriptive words that give the audience a clear idea about what exactly
you want to convey.
In summary, in order to avoid different types of word choice errors,
you need to recognize easily confused words, understand word meanings in
context, and use specific descriptive words whenever necessary.

Writing Conventions
An important convention of academic writing is to cite sources, i.e.
borrowing words or ideas from others and acknowledging the original
authors. It is one of the most effective ways to avoid plagiarism. Except
common knowledge, your personal opinions or experiences, and the results
obtained by your own study, all the information borrowed from others
needs to be cited and credited.
There are three scholarly ways to incorporate the borrowed
information into your own work,i.e. quoting, paraphrasing, and
summarizing. Quoting refers to taking the exact words from the original
source and enclosing them in quotation marks. Paraphrasing means using
your own words to restate another person’s idea. Summarizing is putting the
main ideas of a long text in your own words.
Immediately following your quotation, paraphrase or summary, you
must add an in-text citation to briefly mention the original author’s name
and the publication year, such as (Porter,
1998). Then at the end of your essay, create a reference list to provide
the detailed publication information about all the sources you have referred
to. The format of your citations and references should be in accordance with
the guidelines for a citation style your institution is using or the one
required by your instructor, e.g. MLA, APA, or Chicago. In this chapter, we
illustrate examples of citations and references following the APA style
guidelines.
