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)

The most effective ambition of science is to enhance the lives of people. In my opinion, I agree that science is a key to play a significant role in lives. However, I also believe that there are some negative aspects.

First of all, people's lives become easy in various field of life such as economical, industrial or health sectors because of science. It reduces efforts and time of human being in everyday life. For instance, in ancient time people travel on foot or on the animals from one place to another that took a lot of time and efforts. Vehicles and airplanes that are the inventions of science provide comforts and luxuries.

Secondly, a lot of fatal and incureable diseases are cured with the help of science. X-rays and MRI tests in hospitals are used to locate any disease inside bones and muscle tissues. Lets get back to World War 1, where thousands of people died by just wounds. Use of antibiotics that were created through science cure the wounds.

Regarding to many positive aspects of science to improve people's lives, it also influence lives in negative aspects. Airplanes and vehicles provide luxuries but they are the main causes of air pollution. Air pollution has negative effects on respiratory system and causes diseases in lungs. Water waste from industries that contain a lot of chemicals and other dangerious substances pollute the drinkable water and the water of rivers and oceans. That water damage the aquatic ecosystem and has adverse effects on humans.

In conclusion, science improves the life of people by provinding a lot of facilities that reduce their efforts and time. It also play a rightful part in health. But many health issues developing across prople due to science.

Task Achievement / Task Response: Band 6.0

Your position is generally clear: you agree that science improves people’s lives, while acknowledging harmful effects. The examples about transport, medical imaging, antibiotics, and pollution are relevant and show that you address both the benefits and drawbacks. However, the response does not fully resolve the question of whether improving lives should be science’s most important aim. The negative effects are described, but their significance is not weighed against the benefits or linked clearly to what science’s priorities should be. Some support is also underdeveloped: the World War I example mentions wounds and antibiotics but does not explain the connection precisely. State your extent of agreement more explicitly and develop each example to show how it supports your position.

Coherence and Cohesion: Band 6.5

The response has a clear overall arrangement: an introduction, two paragraphs on benefits, a paragraph on harms, and a conclusion. Sequencing phrases such as “First of all,” “Secondly,” and “In conclusion” make the progression easy to follow, and the contrast between benefits and drawbacks is apparent. This meets the lower-band expectation of coherent organisation and shows some movement towards more flexible progression. However, links can feel mechanical, and some references are unclear—for example, “That water” requires the reader to infer which water is meant. The conclusion also introduces “health issues developing” without clearly connecting this point to the preceding discussion. Use more precise referencing and make the relationship between each paragraph and your overall argument explicit.

Lexical Resource: Band 5.5

You use a relevant range of topic vocabulary, including “respiratory system,” “air pollution,” “aquatic ecosystem,” and “antibiotics,” which helps communicate the subject. There are also attempts at less common expressions, such as “adverse effects” and “fatal diseases.” However, word choice and collocation are often inaccurate or unnatural, as in “effective ambition,” “science is a key to play,” and “provide comforts and luxuries.” Spelling errors such as “incureable,” “dangerious,” and “provinding” are noticeable, and some repeated general words, particularly “science” and “lives,” limit flexibility. Build accuracy by learning common word partnerships and checking spelling; for example, use “aim” rather than “ambition” in this context and “improve people’s quality of life” as a natural phrase.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and more complex sentence forms, including a relative clause in “Water waste from industries that contain…” and a contrastive sentence beginning “Airplanes and vehicles provide luxuries but…”. The main ideas are usually understandable, but some grammatical errors occur across the response. Examples include subject–verb agreement in “it also influence” and “It also play,” article and number problems in “in various field” and “in ancient time,” and an unclear construction in “Regarding to many positive aspects…”. Sentence boundaries and punctuation also need attention, particularly around “Lets get back to World War 1.” Review agreement, articles, plurals, and prepositions, and practise combining clauses accurately. More reliable control of these patterns would make your varied sentences clearer.
