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)

Life improvement should be the major aim of science. I totally agree that science should focus mainly on improving human lives, there are few reasons that affect this approach.

Science has contributed a lot to the modern world. Improving human lives depends on many aspects; health, environmet, foods, and technology. The focus on giving humans a better life has lead to development in other aspects of life. Cars, bicycles, and other means of transportation were invented by scientist to help people move from one place to another. The relief of taking a bus or driving to you destination faster has improved the modern way of living. While scientist research on combating viruses, the measures to avoid them should also be introduced. Health is not just about treating diseases, but also how to avoid contacting any in the first place. There are a lot of new viruses breaking out daily, and scientists need to focus on combating these viruses, and also how to prevent it from becoming a public concern. The ecosystem is also a sector that contributes to improved human life, which is detoriating and needs to be presereved in other to live a better life.

However, in the process of improved human lives, if other aspects are ignored, they affect every other positive developtment overtime. Most of the machine used for scanning and treatment of of certain illness, have radiological side effects. Cars, motorcycles and other automobiles help improve human life, but then produce carbon monoxide, which is harmful to the socitey. Most drugs used in the treatment of some illness have strong side effects overtime. While focusing on improving human lives, they should also prevent the damages caused as a result of this.

Task Achievement / Task Response: Band 6.5

Your position is clear from the opening: you agree that improving people’s lives should be science’s main aim. You address several relevant areas, including transport, health and the ecosystem, and the final paragraph adds a useful qualification: scientific progress should also limit harmful side effects. This gives the response a sound basis and covers the task. However, some points are asserted rather than fully explained. For example, the ecosystem is described as deteriorating, but you do not identify a specific scientific response or explain its effect on people. The transport examples also focus on convenience without considering how they demonstrate science’s wider priority. Develop fewer examples in more depth and connect each explicitly to your position to make the argument more fully supported.

Coherence and Cohesion: Band 6.0

The response has a recognisable overall structure: an introduction, a paragraph presenting benefits, and a final paragraph considering harmful consequences. The shift signalled by “However” is appropriate, and the ideas are generally understandable in sequence. At times, though, the paragraph containing transport, disease prevention and the ecosystem moves quickly between topics, so the progression feels like a list rather than a developed argument. Some links are also unclear: “this approach” in the introduction has no precise reference, and “they” in the final sentence could refer to scientists, drugs or developments. Use clearer topic sentences, group related examples, and make pronoun references explicit. These changes would make the organisation more consistently logical and the cohesion less dependent on basic linking words.

Lexical Resource: Band 5.5

You use vocabulary relevant to the topic, including “transportation,” “combating viruses,” “radiological side effects” and “carbon monoxide.” These choices show an attempt to discuss science and its consequences beyond very basic terms. However, several word-choice and collocation problems reduce precision, such as “the relief of taking a bus,” “contacting” a virus, and “the ecosystem … is detoriating.” There are also noticeable spelling errors, including “environmet,” “presereved” and “socitey,” which make the writing less polished. Aim for accurate, natural combinations and check spelling carefully. A wider range of precise terms for scientific research, public health and environmental protection would help you express the ideas more flexibly.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and more complex sentence forms, including a conditional structure in “if other aspects are ignored, they affect every other positive development.” Most sentences communicate the intended meaning, but some grammatical errors remain. The opening joins two independent clauses with a comma: “I totally agree …, there are few reasons”; use a full stop or a suitable conjunction. Other examples include “scientist research” and “Most of the machine … have,” where subject–verb agreement and number are not controlled. The sentence beginning “While scientist research…” is also awkwardly constructed. Practise accurate agreement, articles and plural forms, and punctuate longer sentences carefully. More reliable control of these patterns would allow your complex sentences to support the argument without distracting the reader.
