Introduction: Your Secret to a Band 7+ Score
Welcome! If you are aiming for a Band 7 or higher in IELTS Writing Task 2, you have probably heard that you need to use complex structures. But what does that actually mean? It doesn’t mean writing long, confusing sentences that are hard to read. In fact, doing that can actually lower your score!
To reach the higher bands, the examiner looks at a criteria called Grammatical Range and Accuracy. For a Band 7, you must use a "variety of complex structures" with "frequent error-free sentences." In this chapter, we will learn how to build these structures simply and accurately so you can impress the examiner and secure your target score.
1. The Foundation: What is a Complex Sentence?
A complex sentence is simply a sentence that contains more than one idea. Think of it like a train: a simple sentence is just the engine, but a complex sentence has the engine plus several carriages attached to it. These "carriages" provide extra information, reasons, or conditions.
Quick Review: You do not need every sentence to be complex. A good Band 7+ essay uses a mix of simple, compound, and complex sentences to keep the writing natural.
2. Relative Clauses: Adding Detail Without Starting New Sentences
Relative clauses use words like who, which, that, and where to add extra information about a noun. This is one of the easiest ways to turn two simple sentences into one high-level structure.
Weak (Band 5-6): Governments should invest in renewable energy. This energy is better for the environment. (Two simple sentences feel "choppy".)
Improved (Band 7+): Governments should invest in renewable energy, which is significantly better for the environment.
How this earns marks: It shows the examiner you can "embed" information, proving you have control over sentence variety.
Try this pattern: [Subject] + [Relative Clause] + [Verb/Result].
Example: People who exercise regularly tend to have lower stress levels.
3. Subordinating Conjunctions: The "Logical Connectors"
To get a high score, you must show the relationship between your ideas. Use words like although, even though, while, whereas, because, and since to connect a dependent idea to a main idea.
The "Contrast" Structure (Very high value):
Weak: Some people like working from home. Others prefer the office.
Improved: While some individuals prefer the flexibility of working from home, others find the office environment more productive.
The "Reason" Structure:
Weak: Pollution is increasing. There are too many cars.
Improved: Pollution is increasing because the number of private vehicles on the road has grown rapidly.
Did you know? Starting a sentence with "Although" or "While" is a classic Band 7+ move. It shows you can handle complex logic right from the start of the sentence!
4. Conditional Sentences: Talking About Possibilities
IELTS Task 2 often asks you to discuss solutions or future impacts. This is the perfect time to use Conditionals (If... then...). This shows the examiner you can discuss hypothetical situations.
Second Conditional (For hypothetical solutions):
If the government increased taxes on sugary drinks, the obesity rate would likely drop.
Common Mistake to Avoid: Don't forget the comma! When the "If" part comes first, you must put a comma before the second part of the sentence.
Correct: If schools taught coding, children would be better prepared for the future.
5. The Passive Voice: Changing the Focus
In Academic writing, we often care more about the action than the person doing it. The passive voice makes your writing sound more objective and formal.
Active (Lower Band): People use computers in almost every job today.
Passive (Band 7+): Computers are used in almost every job today.
Why it matters: Using the passive voice shifts the focus to the topic (computers) rather than the general "people," which is a hallmark of academic English.
6. Nominalization: The Pro-Level Secret
Nominalization is a fancy word for turning verbs (actions) into nouns (things). This makes your writing more concise and sophisticated. It is one of the biggest differences between a Band 6 and a Band 8 essay.
Weak: The crime rate increased, and this worried the public. (Uses a verb)
Improved: The increase in the crime rate caused widespread public concern. (The verb "increased" becomes the noun "increase").
Another Example:
Verb-heavy: If we protect the environment, we can save many species.
Nominalized: The protection of the environment is essential for the survival of many species.
7. The "Accuracy Over Complexity" Rule
Don't worry if this seems tricky at first! Here is the most important advice for the exam: An accurate simple sentence is better than a broken complex sentence.
If you try to write a very long sentence but the grammar is wrong, your score for Accuracy will drop. The goal is to use these structures naturally.
Memory Aid: The 80/20 Rule. Aim to have about 80% of your complex sentences error-free. If your complex sentences are full of mistakes, your score will stay at a Band 6.
Checklist: How to Practice for Task 2
When you practice your next essay, check if you have included at least one of each:
1. A Relative Clause: (e.g., ...which leads to...)
2. A Contrast Sentence: (e.g., Although X is true, Y is...)
3. A Conditional: (e.g., If this happened, then...)
4. A Passive Sentence: (e.g., It is often argued that...)
5. Nominalization: (e.g., The consumption of... instead of "People consume...")
Key Takeaways Summary
Grammatical Range
Use a variety of sentence types (Relative clauses, Conditionals, Subordinating conjunctions).
Grammatical Accuracy
Ensure your complex sentences are "error-free" most of the time to hit Band 7+.
Formal Tone
Use Passive Voice and Nominalization to make your essay sound like an academic paper, not a conversation.
Pacing Tip
In the 40 minutes you have for Task 2, do not spend too much time "counting" your complex sentences. Instead, focus on linking your ideas logically—complex structures will often follow naturally if your logic is strong!
