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 5.0)

Science involves the study of nature. This includes in depth knowledge of biology, physics, chemistry as well as mathematics. It would be fair to say that science concerns relatively important, rather practical matters. Therefore, the impact that science has on our lives can not be neglected.

From the discovery of penicillin to the invention of steam engines, science has not only served as a medium of leasure but also tends to the basic necesseties for survival of mankind. The development of engineering designs, the medical advancements including patient diagnosis and cure, discovery of pharmaceuticals, utilities, daily life consumables are all based on one fundamental which is science.

Task Achievement / Task Response: Band 4.0

The response is relevant to the broad topic of science and human welfare, and the examples of penicillin, steam engines and medical advances could support an argument. However, it does not answer the central question about whether improving people’s lives should be science’s most important aim: no clear position or extent of agreement is stated, and the examples are listed rather than explained. The response also ends without a developed argument or conclusion, and it is substantially below the required minimum length. These omissions leave the task only minimally addressed. To improve, state your position in the introduction, develop two or three reasons with specific explanations or examples, and conclude by directly answering the question.

Coherence and Cohesion: Band 5.5

The writing has a basic sequence: it introduces science, then gives examples of its effects. The opening transition, “Therefore,” signals a relationship between the ideas, and the second paragraph stays broadly focused on science’s contributions. However, the response is too brief to establish a clear overall progression from a position through supporting reasons to a conclusion. The long list in the second paragraph (“engineering designs,” “medical advancements,” and “daily life consumables”) is not grouped or explained, so the relationships between points remain unclear. Build separate body paragraphs around distinct reasons, use linking phrases to show how each example supports your position, and add a concluding paragraph.

Lexical Resource: Band 5.5

The response uses some topic-related vocabulary, including “discovery,” “invention,” “medical advancements,” and “pharmaceuticals,” which helps convey the subject. There are also attempts at more formal phrasing, such as “fundamental” and “necessities for survival.” However, several choices are inaccurate or awkward, including “medium of leasure,” “tends to the basic necesseties,” and “daily life consumables.” Spelling errors in “leasure” and “necesseties” also reduce accuracy. The range is sufficient to communicate the general topic, but more precise collocations and careful proofreading are needed. Prefer familiar, accurate expressions over elaborate wording when unsure, and use vocabulary that directly expresses your argument about science’s aims.

Grammatical Range and Accuracy: Band 5.5

You use both simple sentences and some more developed structures. For example, “This includes in depth knowledge of biology, physics, chemistry as well as mathematics” is a clear sentence, while “From the discovery of penicillin to the invention of steam engines…” attempts a more complex construction. Most of the meaning remains understandable, but control is uneven: “the impact that science has on our lives can not be neglected” has an awkward negative construction, and the second paragraph’s long sentence combines several items without a clear grammatical structure. The opening list also needs clearer punctuation. Practise building accurate complex sentences with one main claim and a supporting clause, and check sentence boundaries, articles and punctuation when editing.
