IELTS Grammar Guide: Essential Rules for Band 7+
To achieve a Band 7, 8, or 9 in IELTS Writing and Speaking, you must score highly in Grammatical Range and Accuracy (GRA). This means you need to make very few mistakes (Accuracy) while using a wide variety of sentence structures (Range). Simple sentences will limit your score to a Band 5 or 6.
1. Complex Sentences (Conditionals & Conjunctions)
Examiners actively look for your ability to connect ideas. Use subordinating conjunctions (although, because, while) and conditional clauses (if, unless) to form complex sentences.
| Grammar Structure | Basic Example (Band 5.5) | Advanced Upgrade (Band 7+) |
|---|---|---|
| Conditional (If) | People exercise. They get healthy. | If individuals engage in regular exercise, they will significantly improve their health. |
| Concession (Although/Even though) | Cars are expensive. Many people buy them. | Although electric vehicles are expensive, they are becoming increasingly popular. |
| Relative Clauses (Who/Which/That) | The government made a law. It was helpful. | The government implemented a new policy which proved to be highly beneficial. |
2. The Passive Voice (Crucial for Task 1)
The passive voice shifts the focus from who did the action to the action itself. This is absolutely essential for IELTS Academic Writing Task 1 (Process Diagrams) and for maintaining an objective, academic tone in Task 2.
| Context | Active Voice (Avoid) | Passive Voice (Band 7+) |
|---|---|---|
| Task 1: Process Diagram | Workers heat the clay in an oven. | The clay is heated in a kiln at a high temperature. |
| Task 1: Map Changes | They built a new hospital in 2010. | A new hospital was constructed in the northern area in 2010. |
| Task 2: General Statements | People generally believe that... | It is generally believed that... |
3. Perfect Tenses
Using a mix of past, present, and future perfect tenses shows the examiner that you have a high level of grammatical control, especially when describing charts with timeframes in Task 1.
| Tense | Usage | Example Sentence |
|---|---|---|
| Present Perfect | Actions that started in the past and continue to the present. | The number of internet users has risen dramatically since 2005. |
| Past Perfect | An action completed before another action in the past. | By 2015, the population had already reached its peak. |
| Future Perfect | Actions that will be completed before a certain time in the future. | By the year 2050, temperatures will have increased by two degrees. |
Top Tips for Grammatical Accuracy
- Check Subject-Verb Agreement: The most common error students make is mismatching singular subjects with plural verbs (e.g., The group of students
areis studying.). - Punctuation Matters: Incorrect use of commas can change the meaning of your sentence and lower your score. Always use a comma after introductory linking words (e.g., However, Therefore, Furthermore,).
- Don't Overcomplicate: Accuracy is just as important as range. Do not write a 4-line sentence if you cannot control the grammar. For a deep dive into formal rules, refer to the British Council Grammar Reference.
