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 most crucial purpose of science must be to enhance the overall well-being of individuals. I personally believe this statement because all kinds of technology, new developments, and education are based on scientific research all the time. That researches allow us to enjoy life more easily, makes people more educated and well-behaved, and give us free time for ourselves.

Nowadays, technologies are improving so rapidly, and all kinds of scientific fields are developing in many ways. For this reason, the average aging of people in the world is increasing, diagnostic capability of the medicine is also increasing, physicians can treat so many illnesses, even those were untreatable before, and there have been developing many different treatment options, which can be used in the patients. All this advantages came from science and its scientific researches and experiments. That is the meaning and important aim of science itself. In my opinion, people should learn about science throughout their lifetime to gain their advantages.

There is no better way to use science as a good advantage in our lives. Some people might think that science should be used as a weapon or for other harmful, threatening purposes. Those are unacceptable thoughts because we had seen so much tragic history about how it could affect people's lives desperately. For example, that atomic bomb fell in Hiroshima, Japan as war weapon and its results are still affecting people.

In conclusion, in my view, everyone in this world should be treated equally, gain the advantages of science, and use it properly to make their life easy and enjoyable.

Task Achievement / Task Response: Band 6.0

Your position is clear: you agree that improving people’s lives should be science’s main purpose, and you support this with examples from medicine and the harmful use of scientific knowledge in warfare. The discussion of longer life expectancy, diagnosis and treatments is relevant, while the Hiroshima example gives a useful contrast. However, some points are asserted rather than fully explained. For instance, the claim that science makes people “more educated and well-behaved” is not developed, and the final paragraph introduces equal treatment and proper use without explaining how these relate to your main argument. Develop each reason with a clearer explanation or specific example, and make the relationship between your supporting points and your position explicit.

Coherence and Cohesion: Band 5.5

The response has a recognisable structure, with an introduction, supporting paragraphs and a conclusion. The progression from benefits in medicine to the dangers of weapons is understandable, and phrases such as “For this reason” and “For example” help signal relationships. However, connections are sometimes mechanical or unclear. The opening paragraph lists several benefits, but the next paragraph focuses mainly on medicine without clearly linking back to all of them. “There is no better way to use science as a good advantage” is also difficult to follow, and “Those” has an unclear reference. The conclusion adds new ideas rather than drawing together the reasons already discussed. Use clearer topic sentences and references, and make each paragraph advance one connected part of the argument.

Lexical Resource: Band 5.5

You use relevant vocabulary for the topic, including “scientific research,” “diagnostic capability,” “treatment options,” and “atomic bomb.” These choices show an attempt to discuss science and its effects beyond very basic terms. However, several word choices and collocations are unnatural or imprecise, such as “average aging,” “gain their advantages,” “use science as a good advantage,” and “affect people’s lives desperately.” Repetition of “science,” “people,” and “advantages” also limits flexibility. Aim for more natural combinations and precise terms—for example, describe life expectancy as rising and say that people benefit from scientific advances. This would make your meaning smoother and more exact without changing your central ideas.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and more complex sentence forms, including a sentence that links scientific progress to medical outcomes and a contrast introduced by “Some people might think.” The overall meaning is generally understandable, but some grammatical errors affect clarity. In “That researches allow us … makes … and give,” the subject and verb forms do not agree, and the list is not grammatically parallel. “Even those were untreatable before” needs a relative structure, while “there have been developing many different treatment options” uses an incorrect verb construction. There are also issues with articles and plurals, as in “all this advantages.” Review agreement, relative clauses, and present-perfect forms, and divide long lists into controlled sentences. More accurate complex sentences would strengthen the response.
