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)

Science becomes the most important part of human lives since after the stone age, as it becomes the source of evolution for the humans and their way of thinking and living. Science has very optimistic effects on well being of ourselves as well as for the environment in which we are living. Science has given us ease of life that we never thought of, the invention of different types of transport, the introduction of different machines making our day to day tasks easier from household chores to academic and professional things. And a great amount of research is still ongoing aiming to improve the people's lives but at the same time it may cause some environmental side affects which we cannot ignore. Our lives become more habitual for having ease and we are no longer having the organic lives or food. For example the micro-oven that we use to heat our frozen foods or to make our food fresh after sometime, it may improve our lives by cutting our time but it may emits caricinogenics that are harmful for ourselves as well as for the environment. In addition to it, the trucks and other means of transportation we use to make our lives easier and overcome the distance issues can also release harmful chemicals in the environment that not only causes harm to human well being but can also cause harm to other species. But through the recent innovations, we are able to overcome these side affects by inventing technologies reducing their impact, but we should keep this in mind that minimizing the impact cannot fully remove the damage.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

Your response addresses the central issue by showing that science can improve daily life while also creating environmental and health risks. Examples such as transport, household machines and food heating are relevant, and the final point that technological fixes cannot remove all damage gives your discussion a clear direction. However, the extent of your agreement is not stated explicitly, so the reader has to infer your position from the examples. Some ideas are also less fully developed: for instance, the possible health effects of the microwave are asserted rather than explained or supported, and the benefits of science receive less evaluation than its risks. State your position directly and develop each example with a clear explanation of its significance.

Coherence and Cohesion: Band 5.0

The ideas are connected in a broadly understandable order: you introduce science’s benefits, then qualify them by discussing possible harms and attempts to reduce those harms. Linking phrases such as “For example” and “In addition to it” help signal relationships between points. However, the response is presented as one long paragraph, which makes the shift from benefits to drawbacks less clear and limits the overall progression. Several ideas are joined in extended sentences, and the repeated use of “and” makes some connections feel mechanical. Divide the response into purposeful paragraphs—for example, an introduction, a paragraph on benefits, one on risks, and a conclusion—and use clearer transitions to show how each point supports your position.

Lexical Resource: Band 5.5

You use a relevant range of topic vocabulary, including “evolution,” “innovations,” “environment,” and “harmful chemicals,” which allows you to discuss both scientific progress and its consequences. There are also attempts at more specific expressions, such as “household chores” and “professional things.” However, several word choices and collocations are inaccurate or awkward, including “ease of life,” “organic lives,” and “side affects.” The repeated use of “harm” and “lives” also limits precision. Choose more natural academic phrasing and check spelling and word forms; for example, describe science as improving “quality of life” and refer to “side effects” or “environmental impacts.”

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and complex sentence forms, including clauses beginning with “since,” “that,” and “which,” and the overall meaning is generally understandable. Some sentences show an ability to connect related ideas, such as the sentence explaining how transport can make life easier while releasing chemicals. However, there are some errors in verb forms, agreement, articles and sentence construction. For example, “it may emits” should use the base verb after “may,” while “chemicals … that not only causes” has a subject–verb agreement problem. The opening sentence also shifts awkwardly between “becomes” and “has given.” Review modal verb patterns, agreement with plural subjects, and sentence boundaries, then proofread longer sentences for consistent tense and structure.
