Under the official IELTS grading rubric, “Grammatical Range and Accuracy” constitutes 25% of your score for both the Writing and Speaking modules. Candidates often struggle not only with basic tense control but also with complex sentence structures, article usage, preposition collocations, and subject-verb agreement. Achieving a Band 7.0 or higher requires minimizing systemic errors while demonstrating a diverse mix of simple, compound, and complex sentences. The following multiple-choice questions target the most frequent grammatical pitfalls encountered by test-takers to help refine your syntax and boost your exam performance.
IELTS Grammar Rules and Common Errors MCQs
1 min read
Correct Answer: b) Society is becoming more dependent on technology.
Explanation:
Abstract nouns and uncountable nouns used in a general, universal sense (like 'society' and 'technology') do not take the definite article 'the'.
Correct Answer: a) a
Explanation:
Although 'university' starts with a vowel letter, it begins with a consonant sound (a 'y' sound: /ju:/). Therefore, it takes the article 'a'.
Correct Answer: a) The environment needs to be protected.
Explanation:
We use 'the' with unique nouns. Because there is only one global environment we share, 'the environment' is the correct form.
Correct Answer: c) Research shows that...
Explanation:
The word 'research' is an uncountable noun in English. It does not take 'a' or an 's', and it takes a singular verb.
Correct Answer: c) The
Explanation:
Countries whose names include words like 'Kingdom', 'States', or 'Republic' always take the definite article 'the'.
Correct Answer: c) People are generally opposed to the new law.
Explanation:
'People' is a plural noun and takes a plural verb ('are'). When speaking generally, no article is needed.
Correct Answer: b) an / a
Explanation:
'Hour' begins with a silent 'h', so it takes 'an' (vowel sound). 'Half' begins with a consonant sound, so it takes 'a'.
Correct Answer: c) Pollution is a major problem in modern cities.
Explanation:
'Pollution' is uncountable and general, so no article is used. 'Modern cities' is general and plural, so no article is used.
Correct Answer: b) He is doing a master's degree at Oxford University.
Explanation:
Proper nouns for universities starting with the name of a place or person (like Oxford University) do not take 'the'. (Note: 'The University of Oxford' does take 'the').
Correct Answer: c) the
Explanation:
We use 'the' because it refers to a specific way—the specific way that we communicate.
Correct Answer: a) is
Explanation:
The phrase 'The number of' acts as a singular subject (referring to the single figure/statistic), so it takes a singular verb.
Correct Answer: b) are
Explanation:
The phrase 'A number of' means 'several' or 'many', and it always takes a plural verb.
Correct Answer: b) are
Explanation:
With 'Neither... nor...', the verb agrees with the noun closest to it. Because 'employees' is plural, the verb is plural ('are').
Correct Answer: b) is
Explanation:
Indefinite pronouns such as everyone, everybody, someone, and anybody always take a singular verb.
Correct Answer: b) Mathematics is my favorite subject.
Explanation:
Nouns ending in '-ics' (like Mathematics, Physics, Economics) are singular when referring to a subject of study.
Correct Answer: a) is
Explanation:
The actual subject is 'One', which is singular. The phrase 'of the main reasons' is a prepositional phrase. Therefore, the verb is 'is'.
Correct Answer: a) There is a significant increase and a slight decrease in the data.
Explanation:
When a compound subject follows 'there is/are', the verb typically agrees with the first noun in the list. 'A significant increase' is singular.
Correct Answer: b) was
Explanation:
'Each of' is followed by a plural noun but takes a singular verb because 'Each' is the subject.
Correct Answer: b) are
Explanation:
When 'The majority of' is followed by a plural countable noun (students), it takes a plural verb.
Correct Answer: b) has

Correct Answer: c) The internet provides a lot of information.
Explanation:

Correct Answer: c) They bought some new equipment for the lab.

Correct Answer: b) Despite the rain, we went out.

'Despite' is a preposition and is followed directly by a noun. It never takes 'of' ('In spite of' is correct, but 'Despite of' is a common error). 'Although' must be followed by a full clause (subject + verb).
Correct Answer: b) However
Explanation:
The second sentence introduces a contrast or negative point compared to the first positive point. 'However' effectively introduces this contrast.
Correct Answer: c) due to
Explanation:
'Due to' is a prepositional phrase followed by a noun ('the heavy fog'). 'Because', 'since', and 'as' are conjunctions that must be followed by a full subject and verb.

Correct Answer: c) in order to
Explanation:
'In order to' is followed by a base verb to express purpose. ('So that' requires a subject and modal verb, e.g., 'so that he could pass').
Correct Answer: c) In spite of
Explanation:
'In spite of' (or 'Despite') is followed by a noun phrase, such as 'the fact that'. 'Although' is followed directly by a subject and verb, not 'the fact that'.
Correct Answer: c) on the other hand
Explanation:
'On the other hand' introduces a contrasting viewpoint or negative aspect of the previously mentioned topic.
Correct Answer: b) rains
Explanation:
The First Conditional describes a real future possibility. The 'if' clause uses the Present Simple ('rains'), and the main clause uses 'will' + base verb.
Correct Answer: c) were
Explanation:
In formal English and IELTS writing, 'were' is used for all subjects in the 'if' clause of a Second Conditional (hypothetical) sentence.
Correct Answer: b) had taken
Explanation:
The Third Conditional describes an unreal past situation. It requires the Past Perfect ('had taken') in the 'if' clause, and 'would have' + past participle in the main clause.
Correct Answer: c) would be
Explanation:
This mixed conditional connects an unreal past event ('had caught') to a present result ('now'). The main clause uses 'would' + base verb.
Correct Answer: a) Unless you study, you will fail.
Explanation:
'Unless' means 'if not'. Therefore, 'Unless you study' translates to 'If you do not study'.
Correct Answer: b) provided that
Explanation:
'Provided that' means 'on the condition that' or 'only if', which perfectly links the two ideas logically.
Correct Answer: b) Had I
Explanation:
In formal English, the 'if' can be dropped from a third conditional by inverting the auxiliary verb and subject: 'Had I known' = 'If I had known'.
Correct Answer: c) in case
Explanation:
'In case' is used to describe doing something as a precaution for a future possibility.
Correct Answer: c) But for
Explanation:
'But for' is a formal phrase meaning 'if it had not been for'. It is commonly used in hypothetical situations.
Correct Answer: b) If the price of oil rises, the economy will suffer.
Explanation:
In the First Conditional, we never use 'will' in the 'if' clause. The present simple 'rises' is correct.
Correct Answer: b) A new law was passed by the government.
Explanation:
The object ('A new law') becomes the subject, followed by the 'be' verb ('was') and the past participle ('passed').
Correct Answer: b) is being built
Explanation:
'At the moment' requires continuous tense. The passive form is 'is/are being' + past participle.
Correct Answer: c) are picked
Explanation:
When describing a manufacturing or natural process, the Present Simple Passive ('are picked') is used because the person doing the action is unknown or unimportant.
Correct Answer: b) It is believed that the earth is getting warmer.
Explanation:
'It is believed that...' is a formal impersonal passive structure frequently used in IELTS Writing to introduce general opinions.
Correct Answer: b) must be submitted
Explanation:
The passive structure for modal verbs is: modal ('must') + 'be' + past participle ('submitted').
Correct Answer: c) has been solved
Explanation:
Present perfect passive is formed with 'has/have been' + past participle.
Correct Answer: a) to be
Explanation:
The passive reporting structure uses 'Subject + is said + to infinitive'.
Correct Answer: c) washing
Explanation:
After the verb 'need', we can use the gerund ('washing') or the passive infinitive ('to be washed') to express a passive meaning.
Correct Answer: b) Having been told
Explanation:
The perfect passive participle 'Having been told' means 'Because she had been told'.
Correct Answer: c) The accident was happened yesterday.
Explanation:
The verb 'happen' is intransitive; it does not take an object, and therefore cannot be used in the passive voice.
Correct Answer: d) whose
Explanation:
'Whose' is a possessive relative pronoun indicating that the research belongs to the scientist.
Correct Answer: b) The book, which I read yesterday, was excellent.
Explanation:
In a non-defining relative clause (set off by commas), 'which' must be used for things. 'That' cannot be used after a comma.
Correct Answer: c) where
Explanation:
'Where' is used as a relative pronoun for places. It means 'in which'.
Correct Answer: b) whom
Explanation:
'Whom' is the object form of 'who' and must be used directly after a preposition like 'with', 'for', or 'to'.
Correct Answer: c) The company where I work for is going bankrupt.
Explanation:
You cannot use 'where' and the preposition 'for/in' together. It should be either 'The company where I work' or 'The company which I work for'.
Correct Answer: c) why
Explanation:
'Why' is the correct relative pronoun to follow the noun 'reason'.
Correct Answer: b) The man standing in the corner is my brother.
Explanation:
An active relative clause ('who is standing') can be reduced to a present participle ('standing').
Correct Answer: b) The goods made in China are cheap.
Explanation:
A passive relative clause ('which are made') reduces to a past participle ('made').
Correct Answer: b) My father, who is 65, retired last year.
Explanation:
Because a person only has one father, the clause 'who is 65' is extra information (non-defining) and must be enclosed in commas. 'That' cannot be used.
Correct Answer: c) that
Explanation:
After indefinite pronouns like 'everything', 'something', 'nothing', or 'all', the relative pronoun 'that' is used, never 'what' or 'which'.
Correct Answer: b) its
Explanation:
'Its' is the possessive pronoun. 'It's' is a contraction for 'it is' or 'it has', which is incorrect here.
Correct Answer: b) affect
Explanation:
'Affect' is a verb meaning to influence. 'Effect' is a noun meaning the result.
Correct Answer: b) effect
Explanation:
Here, a noun is required after the article 'an'. 'Effect' is the noun form.
Correct Answer: d) a or c
Explanation:
'Amount' and 'quantity' are used with uncountable nouns (like water). 'Number' is strictly used with plural countable nouns.
Correct Answer: b) fewer
Explanation:
'Fewer' is used with countable plural nouns (cars). 'Less' is used with uncountable nouns.
Correct Answer: b) lose
Explanation:
'Lose' is a verb meaning to misplace something. 'Loose' is an adjective meaning not tight.
Correct Answer: b) than
Explanation:
'Than' is a conjunction used for making comparisons. 'Then' is an adverb relating to time.
Correct Answer: b) whether
Explanation:
'Whether' is a conjunction expressing a doubt or choice between alternatives. 'Weather' refers to the climate.
Correct Answer: b) except
Explanation:
'Except' means 'excluding'. 'Accept' is a verb meaning to receive or agree.
Correct Answer: a) principal
Explanation:
A 'principal' is the head of a school or a primary person/thing. A 'principle' is a fundamental truth or rule of conduct.
