IELTS Task 2 Topic Sentence Examples (Weak vs Strong)
See how precise topic sentences create paragraph focus without memorised phrases or unnecessary background.
Quick answer
A strong IELTS Task 2 topic sentence states the paragraph's main claim in a specific way and makes its relationship to your overall position clear. It should not merely announce the topic, repeat the question, or list every supporting detail. The sentences that follow should be able to explain, qualify, or illustrate that one claim without changing direction.
A topic sentence is a promise to the reader
When you begin a paragraph with a claim, you promise that the remaining sentences will develop it. If the opening says that public parks improve health but the paragraph shifts to tourism revenue, the reader has to rebuild the logic. That weakens coherence even if both points are relevant to cities.
Write the topic sentence after choosing your best reason. Include enough detail to establish direction, but leave the explanation and evidence for later sentences. This creates a natural hierarchy: claim first, support second.
Avoid announcement and question-echo openings
Phrases such as 'This paragraph will discuss' use words without contributing meaning. Similarly, replacing a few words from the prompt does not establish your argument. Examiners need to follow the progression of ideas, not see a memorised signpost.
A useful test is to read only your thesis and the first sentence of each body paragraph. Together, they should form a compact outline of the whole essay. If one topic sentence could fit almost any question, make it more specific.
- Name the paragraph's exact subject.
- State the benefit, cause, problem, or contrast you will prove.
- Keep examples and minor details out of the opening sentence.
- Check that every later sentence supports the opening claim.

Frequently asked questions
Should every IELTS Task 2 paragraph start with a topic sentence?
Body paragraphs should normally begin with a clear controlling idea. The sentence does not need a formula, but the paragraph's purpose should be visible immediately.
Can a topic sentence contain two ideas?
It can contain two tightly connected parts, such as a concession and main claim. Two unrelated benefits or problems usually make the paragraph harder to develop coherently.
