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 6.0)

Many people believe that the basic goal of scienctific knowledge should be to improve people's lives. While critics argue against it. I agree with this view and I believe that science should be used to facilitate humans rather than destructive or dangerous inventions.

Since the begining of human race there are developments in the field of technology. Human had passed through different ages such as stone age, bronze age ect. The modern inventions we see today have resulted as an outcome of long journey of scientific research.

Modern technology has improved people's lives but at the same time many dangerous inventions put human kind at the verge of destruction. Many people think that science should be solely used to improve people's live not for creating dangerous weapons.

On the one hand, many people think that scientific research and knowledge should be restricted to innovations which are beneficial for mankind, such as latest medicines, medical treatments and technologies to ease human life by saving their time and energy. For instance automatic machines and vehicles have improved quality of life and has made world a better place for many people especially disabled individuals. Proponents of this view suggest further research in different fields of life to find cure of many diseases and tackle the present day problems like environmental pollution.

On the other hand, there are many inventions which causes more harm than good. Such as dangerous war weapons like nuclear weapons in the name of defence. These inventions are a contant threat to humanity and their use should be discourages.

In conclusion, I largely agree with the concept that science should be used for beneficial purposes to improve quality of life. I suggest international authorities should pass legislations for promotion of useful scientific reseach for more peaceful purposes to serve humanity.

Task Achievement / Task Response: Band 6.5

Your position is clear from the introduction: you agree that science should improve people’s lives and oppose harmful inventions. You address both beneficial applications, such as medicines and technologies that assist disabled people, and risks such as nuclear weapons, then return to your view in the conclusion. This covers the task well. However, some ideas are more fully explained than others: the examples of medical research and pollution are named but not developed, and the historical paragraph about earlier technological ages does not clearly support your argument. To strengthen the response further, explain how a specific scientific advance improves lives and why harmful research should be limited, while maintaining your clear position throughout.

Coherence and Cohesion: Band 6.0

The response has a recognisable structure, with an introduction, background paragraph, two contrasting body paragraphs and a conclusion. The progression from benefits to dangers is generally easy to follow, and signposts such as “On the one hand” and “On the other hand” help distinguish the arguments. However, some connections are mechanical or unclear. The opening “While critics argue against it” is left as a fragment, and “Such as dangerous war weapons” is also not a complete sentence. The historical paragraph interrupts the argument’s development because its relevance is not made explicit. Improve cohesion by linking each paragraph directly to your position and using complete sentences rather than relying mainly on formulaic transitions.

Lexical Resource: Band 6.0

You use an adequate range of topic vocabulary, including “scientific research,” “medical treatments,” “environmental pollution,” and “nuclear weapons,” which makes the main ideas clear. There are also attempts at more formal phrasing, such as “beneficial purposes” and “serve humanity.” However, some word choices and collocations are inaccurate or awkward, including “at the verge of destruction,” “inventions which causes more harm,” and “promotion of useful scientific research.” Spelling errors such as “scienctific,” “begining,” “contant,” and “reseach” also reduce accuracy. Aim for more natural combinations—for example, “on the verge of destruction” and “pose a constant threat”—and proofread carefully for spelling and word forms.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and complex sentence forms, including a contrastive opening and longer sentences explaining the benefits of research. Meaning is generally understandable, but some grammatical errors remain and occasionally make the writing less smooth. For example, “While critics argue against it” is a dependent clause without a main clause, while “inventions which causes” has a subject–verb agreement error. In “automatic machines and vehicles … has made,” the plural subject also requires a plural verb. The sentence beginning “Such as dangerous war weapons” is incomplete. Practise checking clause completeness, agreement and verb forms, and use punctuation to connect ideas accurately. More consistently controlled complex sentences would improve the response.
