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)

I agree with this statement that the aim of science should be to improve human lives. It also should focus on the other aspects of the world.

One the one hand, science has played a vital role in the field of medical. By the help of the science, we can overcome to very dangerous diseases. Now a days, doctors can do their medical treatments and complicated surgeries easily. Polio and covid vaccines almost finished the disease. So, science has play an important role in medical feild.

Furthermore, science has changed our daily life and daily tasks. Now, we have alot of the electrical appliances in our homes. We can do our complicated tasks in a wasy way. We can save our time by these technologies. Science has made farming advanced. By that, farmers can grow more food in their farms. They used advanced technologies for this purpose.

From my perspective, the main focus of science should be on human lives. The astronomers want to access to the other planets and Moon. Some science is used for army and making of different kinds of weapons. These are important for the safety of the country. But if human life do not move smoothly, then all other purposes of science being wasted. Firstly, science should improve the human's lives.

In conclusion, the main aim of the science should be make better human live instead of all other aspects of the world .

Task Achievement / Task Response: Band 5.5

Your position is clear: you agree that science should primarily improve human lives, and you give relevant examples from medicine, household technology and farming. The final paragraph also acknowledges other purposes, such as space exploration and national defence, before reaffirming your view. However, the response addresses the task only partially because several points are asserted rather than explained. For example, saying vaccines “almost finished the disease” does not clarify their impact, and the farming example is not developed with a specific consequence. The claim that other scientific aims are wasted if life does not “move smoothly” also needs clearer reasoning. The response is 11 words below the required minimum; develop and support the existing examples to meet the task fully.

Coherence and Cohesion: Band 6.0

The response has a recognisable overall arrangement: an introduction, paragraphs on medical and everyday benefits, a paragraph considering other scientific aims, and a conclusion. Linking expressions such as “Furthermore,” “From my perspective,” and “In conclusion” help signal the stages of the argument. This supports a coherent overall structure. However, progression within paragraphs is sometimes abrupt: the discussion moves from household appliances to farming without explaining their connection, and the final body paragraph shifts quickly from astronomy to weapons and then to human welfare. Some links are mechanical, and references such as “By that” are not fully clear. To strengthen cohesion, organise each paragraph around one main claim and use explicit explanations to show how each example supports it.

Lexical Resource: Band 5.0

You use enough topic-related vocabulary to communicate the main ideas, including “medical treatments,” “complicated surgeries,” “electrical appliances,” “farming,” and “weapons.” These examples show an attempt to discuss several areas of science. However, the range is limited and some word choices or collocations are noticeably inaccurate, which can make meaning less precise. For instance, “field of medical” and “access to the other planets” are not natural expressions, while “finished the disease” does not clearly convey the intended meaning. Spelling errors such as “feild” and “wasy” also reduce accuracy. Build a more precise set of topic phrases and check spelling, word forms and common collocations when revising.

Grammatical Range and Accuracy: Band 5.0

You use mostly straightforward sentence patterns and attempt some longer structures, including “But if human life do not move smoothly, then all other purposes of science being wasted.” This shows an effort to express a conditional relationship, but the construction is faulty. Errors also occur in verb forms and agreement, as in “science has play,” “farmers can grow” followed by “They used,” and “human life do not.” Articles and prepositions are also inconsistent, for example in “the aim of the science” and “By the help of the science.” These frequent errors sometimes make sentences difficult to follow, although the overall meaning is generally recoverable. Practise accurate simple sentences first, then build controlled conditional and complex forms, checking agreement and verb forms.
