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 6.5)

It is often argued that science's main aim should be to improve people's lives. This essay totally agrees with the statement and it is important to prioritise human's life using every available resource, not only science.

Science is a vital part of everyday life, from counting simple numbers, to heating food using a microwave, from saving lives using biology to exploring space using astrophysics. Science is the foundation of every subject thought in schools and universities. Governments should invest more in science and technology to enhance quality of life and ease people's hardships.

Moreover, science is not only limited to what we have today, in fact, it is an ocean of knowledge and skills. For instance, the computer that I am using to write this essay was build using certain hardware elements which were created using science, its software has been created using various algorithms using numbers and now this computer can be used for thousands of other activities and tasks and ease our daily life. Further more, millions of people lost their lives by being diagnosed with different diseases like diabetes, which is now curable by taking a medication named insulin, which was produced after years of research and experiments by scientist in 1922.

To summarise, I believe science and technology are invaluable resources not only for humans, but also for other species and the Earth, and it can be developed further with appropriate investment and resources. And I strongly agree that the most important aim of science should be to improve people's lives and new innovations.

Task Achievement / Task Response — Band 6.5

The response addresses the prompt by clearly stating a position in favor of the idea that science should prioritize improving human lives. The essay is well-structured, with a clear introduction, body paragraphs, and a conclusion. However, the development of ideas is somewhat limited. While you provide examples like the computer and insulin, the discussion could be deepened by exploring the potential conflict between pure scientific discovery and applied science. The argument remains a bit general, and the conclusion introduces a slightly new point about 'other species and the Earth' which was not previously developed in the body paragraphs. To reach a higher band, ensure that all points mentioned in the conclusion have been thoroughly explored in the main body.

Coherence and Cohesion — Band 7.0

The essay demonstrates a clear logical progression. You use cohesive devices such as 'Moreover', 'For instance', and 'To summarise' to link ideas effectively. Paragraphing is used appropriately to separate distinct points. However, some transitions feel slightly mechanical, and the referencing in the third paragraph (e.g., 'this computer can be used for thousands of other activities') is a bit repetitive. The flow is generally smooth, but the connection between the broad statement about science and the specific example of the computer could be more tightly integrated to improve the overall cohesion of the argument.

Lexical Resource — Band 6.0

You demonstrate an adequate range of vocabulary for the task, using terms like 'invaluable resources', 'prioritise', and 'diagnosed'. There are some minor errors in word choice and collocation, such as 'subject thought in schools' (should be 'taught') and 'human's life' (should be 'human life'). While you attempt to use more sophisticated vocabulary, some phrasing is slightly awkward. To improve, focus on using more precise academic collocations and ensure that your word forms are accurate. The range is sufficient to convey your meaning clearly, but it lacks the flexibility and precision required for a higher band.

Grammatical Range and Accuracy — Band 6.0

The essay uses a mix of simple and complex sentence structures. There are several grammatical errors, such as 'was build' (should be 'was built') and 'scientist' (should be 'scientists'). Additionally, there are some punctuation issues, such as the comma splice in the first paragraph. While these errors do not impede communication, they occur frequently enough to prevent a higher score. To improve, focus on subject-verb agreement, consistent verb tense usage, and ensuring that complex sentences are punctuated correctly. Increasing the variety of complex structures while maintaining accuracy will help elevate your score.
