IELTS Writing Task 2 question

The most important aim of science should be to improve people’s lives. To what extent do you agree or disagree with this statement? Give reasons for your answers and include any relevant examples from your own knowledge or experience.

 

Student answer (Band 5.5)

the modern science is working so hard for our future generations and well beings of societies.

i agree to this argument that science should aim on improving peoples lives.

If we look back a hundred years ago our world population was less then 2 billion people, because the average life expectancy was under 40 years old. People could not live longer due to lack of health cures. women would die while giving birth due to lack of doctors awareness.

But if we look today our society is much healthier then before, Our Average life expectancy is increased from 40 years old to 70 years old, Our current world population is about 8 Billion. which is well above 2 Billion from 100 years ago. this is the best example of our society.

so we came this far by the help of sceince. our science found cures for illness and all. and we have still yet so much to find about.

I agree to this fact that science should aim to improve our lifes beachse now scientists are not alone we have ariticial intelligence with us now. which makes new research much more easier for todays world. This is the main reason i find this to be acomplished by us in the future.

so we can increase our health and life expectancy significantly and enjoy a healthy life in our forceable future. so our next generation can continue our legacy and work hard in this AI era to continue working to aim for better life for people.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

Your position is clear: you agree that science should aim to improve people’s lives, and you support this with relevant examples about medical advances, life expectancy and childbirth. These points address the question and give the response a consistent central argument. However, the discussion focuses almost entirely on health, so the broader importance of science and whether improving lives should be its most important aim are not fully explored. The reference to artificial intelligence is promising, but the claim that it makes research easier is not explained with a specific example. To develop the response further, explain how the evidence supports your view and consider another area, such as communication or food production, while clarifying why improving lives should take priority.

Coherence and Cohesion: Band 5.0

The response has a recognisable sequence: it states agreement, contrasts life in the past with the present, and then looks towards future scientific progress. This helps the reader follow the main line of thought. However, ideas are often joined mechanically with repeated transitions such as “But if we look today” and “so,” and several points are placed together without clear paragraph breaks. The movement from population figures to medical cures, then to AI and future generations, is not always smoothly explained. Use separate paragraphs for the position, historical evidence and future implications. Vary linking expressions and make the relationship between each example and your main claim explicit; this would create clearer progression rather than a series of loosely connected statements.

Lexical Resource: Band 5.0

You use relevant vocabulary for the topic, including “life expectancy,” “cures,” “scientists,” “research” and “artificial intelligence,” so the main ideas are generally understandable. However, the range is limited and several noticeable spelling and word-choice errors reduce precision, including “sceince,” “beachse,” “ariticial” and “forceable.” Some phrases are also unnatural or imprecise, such as “aim on improving,” “doctors awareness” and “our society is much healthier then before.” Try to use accurate topic-specific collocations and check spelling carefully. More precise terms such as “medical treatment,” “maternal deaths” and “scientific research” would help express your examples clearly and avoid relying on repeated general words such as “life” and “work.”

Grammatical Range and Accuracy: Band 5.0

You attempt both simple statements and longer sentences, for example the sentence beginning “If we look back a hundred years ago,” which introduces a reason and supporting detail. However, the range is limited, and attempts to connect several clauses often produce faulty sentence boundaries or punctuation. For instance, “Our current world population is about 8 Billion. which is well above 2 Billion…” leaves a dependent clause as a fragment, while “so we came this far by the help…” begins a new sentence without appropriate capitalisation. There are also errors in articles, agreement and sentence construction, as in “the modern science” and “our Average life expectancy is increased.” Practise forming accurate complex sentences and check capitals, full stops and verb forms when editing.
