Top 10 IELTS Grammar Mistakes and How To Avoid Them

IELTS Grammar is assessed in both the Writing and Speaking tests, comprising 25% of the total mark for each test. The examiner will look at the range of grammatical structures you can use, but more importantly, they will assess the grammar’s accuracy.
25% of your marks in the writing and speaking tests come from using appropriate grammar structures that are error-free. Unfortunately, people often make frequent grammar mistakes when learning a new language. In fact, if more than 50% of your sentences have any errors in them, you will not get more than band 6 for grammatical range and accuracy. In other words, to score 7 or higher, you should try to make more than half of your sentences completely error-free.

After marking thousands of IELTS tests, I have noticed that the same errors are made repeatedly. Below are the top 10 mistakes and some advice on how to avoid them.

Most people make all or some of these mistakes in their writing and speaking tests. A good thing to do is show some of your practice tests to a teacher or native speaker and establish your common errors. When you know your common grammar errors, you can easily fix them with practice and raise your score.

        1. Use of the word ‘the’

We use the:

• when there is only one of something in a particular area: the government, the police, the bridge, the river, the hospital
• when there is only one in the entire world: the internet, the environment, the ozone layer, the atmosphere
• with cardinal numbers: the first, the second, the third
• with superlatives: the worst, the shortest, the lowest, the most beautiful, the least impressive
• with places where the name refers to a group of islands or states: the USA, the UK, the Maldives, the Middle East, the United Arab Emirates
• before nouns which describe general things: exercise is good for the body, the motorbike is the most common form of transport in Asia, the   role of the teacher has changed in recent years
• before abstract nouns used to describe a situation, process, quality or a change: over the years, the development of the town accelerated,   the frequency of violent crime decreased over the period, the improvement in living standards

We don’t use the:

• to talk generally, we drop the word ‘the’ and use the plural: dogs don’t like cats, people with dyslexia have reading problems, Japanese cars are very reliable, and German products are very high quality.
• with a single place or country: Ireland, China, Vietnam, Europe, South America

Countable and Uncountable Nouns

Some nouns in English are uncountable and will, therefore, always be in the singular form and never plural. Some common nouns that students often get wrong on the IELTS test are:

If a noun is uncountable, you cannot use:

a plural verb: There were many traffic in the city.
a number: three advice, four food
a few, a couple, many, a number of: a number of literature, a few research
a/an: a happiness, an entertainment

Noun-Verb Agreement

The verb must agree with the noun. If you use a plural noun, you must use a plural verb and vice versa.

Example:

There is some dogs outside.

There is some food in the kitchen.

Here are some homework for you.

There are some eggs in the kitchen.

–ing or to + infinitive
We use to + infinitive verb after the following verbs: learn how, would like, want, seem, refuse, promise, prepare, offer, learn, hope, help, deserve, decide, afford, and ask.

Example:

It is important to learn how to speak English

Most people cannot afford to go on holiday every year.

I would like to study overseas.

Note: ‘like’ can be followed by –ing or to + infinitive.

We use verb–ing after the following verbs: suggest, recommend, practice, mind, keep, involve, imagine, give up, finish, enjoy, deny, consider, carry on, and avoid.

Example:

I would recommend checking your writing for mistakes.

You should avoid drinking coffee after 6 pm.

I’ve finished writing my essay.

Use Of Articles Before Noun Phrases

You should include a/an before adjective singular noun combinations: a massive improvement, a steady increase, an overall majority, a very small percentage, a really strong argument.

Some exceptions include the word ‘of’ after the noun phrase: a wide range of, an equal number of, a large/small number of, a small/large/equal proportion of.

Exceptions: quite a few people, to a certain extent/degree

Use of Commas

In the IELTS writing test, we often use phrases called ‘discourse markers’ or ‘liking phrases’ to link our ideas together, such as on the one hand, on the other hand, however, for example, nevertheless, firstly, secondly, in conclusion, in summary.

We normally use a comma after a discourse marker that introduces a sentence:

Firstly, the main cause of pollution is motor vehicles.
On the one hand, motor vehicles are said to be the main cause.
However, pollution from industry may also be to blame.
To sum up, the causes of pollution are mostly man-made.
We also use commas on either side of discourse markers in the middle of sentences:

Fossil fuels are mostly to blame for global warming; however, some people believe this is a natural process.
Fossil fuels are mostly to blame for global warming, for example, from cars and factories.
Verb Tenses
Always consider which of the following tense you should use:

Present simple:

things that are always true (the sky is blue)
general statements of fact (I was born in 1982)
habits (I go to sleep every night at 11 pm)

Present continuous:

an action at the moment of speaking
something in progress this week, month or year

a general activity in progress recently

Apostrophes

We use apostrophes to shorten words or make contractions:
Cannot-Can’t
Do not- Don’t
I will- I’ll
Contractions are normally used in spoken English and should not be used in academic writing tasks.

We can also use apostrophes to show possession:

John’s book
Mary’s brother
We don’t use apostrophes with possessive pronouns such as:

The dog has broken its
The book is not theirs it’s ours.
