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)

There has been a considerable debate about whether the most crucial aim of science should be to improve people's lives. I personally agree with this view since science's main aim is to enhance the way of living.

The main reason why science's aim is to improve the quality of lives is that science was developed to change the way people interact with life, as it has led to various improvements, including testing whether water is drinkable or not and whether food is edible or not. For instance, this helps individuals avoid drinking or eating contaminated food or water. This is particularly important because consuming unsafe food or water can lead to serious health problems and negatively affect people's quality of life. As a result, people can avoid catching illnesses or experiencing other health problems.

Another significant reason why science improves lives is that it has created the technology we use today, which makes it easier for us to deal with a lot of challenges in our daily lives. For example, phones have made it easier for people to communicate with each other instead of using papers and sending them to mailboxes. Modern communication technology allows people to contact their friends, relatives and colleagues almost instantly, regardless of the distance between them. As a result, individuals can communicate whenever they need to without dealing with the inconvenience of traditional mail.

In conclusion, I strongly agree that the main aim of science should be to improve people's lives, as it has contributed to better health and made everyday life easier through technological developments.

Task Achievement / Task Response — Band 6.5

The response addresses the prompt clearly and maintains a consistent position throughout. The ideas are relevant, focusing on health and communication as key areas where science improves lives. However, the development of these ideas is somewhat limited. For instance, the discussion on food safety is a bit repetitive, and the examples provided are quite basic. To reach a higher band, you should aim to explore the implications of your arguments more deeply, perhaps by considering the broader societal impact or the potential counter-arguments regarding the ethical or theoretical aspects of science. The structure is logical, but the depth of analysis remains at a functional level rather than a fully extended one.

Coherence and Cohesion — Band 7.0

The essay is well-organized with a clear introduction, two body paragraphs, and a conclusion. Each paragraph has a central topic sentence, and the progression of ideas is logical. You use cohesive devices such as 'For instance', 'As a result', and 'In conclusion' effectively to link your points. However, the transitions between sentences can feel slightly mechanical at times. To improve, try to vary your linking phrases and ensure that the flow between sentences is more natural. The paragraphing is appropriate, and the overall structure supports the reader's understanding of your argument.

Lexical Resource — Band 6.0

You demonstrate an adequate range of vocabulary for the task, using words like 'considerable', 'contaminated', and 'inconvenience' correctly. The language is generally precise and conveys your meaning well. However, the vocabulary is somewhat repetitive, particularly the phrase 'improve people's lives' and 'aim of science'. To achieve a higher score, you should attempt to use more sophisticated synonyms and collocations to demonstrate a wider lexical range. For example, instead of repeating 'improve', you could use 'enhance', 'ameliorate', or 'facilitate advancements'. The current range is sufficient but lacks the flexibility and precision required for higher bands.

Grammatical Range and Accuracy — Band 6.5

The essay shows a mix of simple and complex sentence structures. You use relative clauses and conditional-like structures effectively, such as 'regardless of the distance between them'. There are very few grammatical errors, and your punctuation is generally accurate. While the sentences are clear, they are not particularly complex or varied in their construction. To improve, try to incorporate a wider variety of grammatical structures, such as passive voice or more advanced subordinating conjunctions, to show greater control. The current level of accuracy is good, but the range of structures is somewhat limited.
