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)

It is widely acknowledged that the primary objective of science must be to improve the lives of individuals in society. In my view, I partially agree with this statement. Therefore, this essay will explore the positive and negative aspects of science before drawing a balanced conclusion.

To begin with, a substantial number of individuals believe that science helps us in every field of life including technology, education, the environment and agriculture. For instance, in the sector of technology, science help us in various ways like building artificial intelligence (AI), the internet, computers and other electronic devices. Moreover, in the field of education, science provides digital tools, online platforms and resources that make learning more convenient. Additionally, in agriculture, science created effective fertilizers which boost the quantity and quality of crops, and pesticides which kill insects. Furthermore, in the environment, science has developed technologies that control harmful greenhouse gases and protect the atmosphere from global warming.

On the other hand, a distinct members of society argue that science also brings drawbacks in the field of education, technology, agriculture and the environment. Specifically, in technology sector, if adolescents use mobile phones and playing games on other electronic devices for more than 12 hours per week, they will automatically lose interest in their studies. Similarly, in educational department, the excessive use of digital tools and heavily reply on digital screen cause a harmful impact on students' mental and physical health. Likewise, in the field of environment, the heavy use of cars and ships require a large quantity of fossil fuels, and as a result, they emit a large quantity amount of carbon dioxide (CO2) which badly effect the environment. Finally, in agriculture, when many individuals heavily reply on chemical fertilizers and pesticides, it causes severe health problems, including cardiovascular, lung issues and stomach disorders.

In conclusion, science brought significant improvements in the sectors of technology, education, agriculture and the environment. Besides, its drawbacks cannot ignored.

Task Achievement / Task Response: Band 6.0

Your position is stated clearly as partial agreement, and you provide relevant examples across technology, education, agriculture and the environment. The discussion also recognises that scientific developments can have harmful consequences, so the response addresses both sides of the issue. However, the argument does not fully explain what should make improving lives science’s most important aim, or how this aim should be balanced against other purposes such as expanding knowledge. Some examples are asserted rather than developed: the claim that adolescents using devices for more than 12 hours weekly will “automatically” lose interest in study needs explanation or support. The conclusion is also very brief and does not restate your balanced position clearly. Develop fewer examples in more depth and connect them directly to your view.

Coherence and Cohesion: Band 6.5

The essay has a clear overall arrangement: an introduction, a paragraph presenting benefits, a contrasting paragraph on drawbacks, and a conclusion. This makes the main direction easy to follow, and signposts such as “To begin with,” “On the other hand,” and “In conclusion” help identify each stage. The organisation is therefore coherent, but some linking is mechanical: “Moreover,” “Additionally,” “Furthermore,” and “Likewise” repeatedly introduce lists rather than showing how ideas relate. The repeated sequence of technology, education, environment and agriculture also makes the paragraphs feel formulaic. Some references are unclear, as in “they emit” after mentioning cars and ships alongside fossil fuels. Use a wider range of links that express cause, contrast or consequence, and make references more precise.

Lexical Resource: Band 6.0

You use an adequate range of topic vocabulary, including “artificial intelligence,” “digital platforms,” “fertilizers,” “pesticides,” “fossil fuels” and “greenhouse gases.” These terms make the subject matter clear, and you attempt more formal phrasing such as “primary objective” and “significant improvements.” However, some word choices and collocations are inaccurate or unnatural: “a distinct members,” “heavily reply on,” “a large quantity amount,” and “badly effect” weaken precision. “Drawbacks in the field of education, technology, agriculture and the environment” is also broad and repetitive. Aim for accurate collocations and vary repeated general terms such as “field” and “science.” These errors do not prevent understanding, but more controlled phrasing would make the argument more precise and natural.

Grammatical Range and Accuracy: Band 6.0

You use a mix of simple and complex sentence forms, including conditional and cause-and-effect structures: “if adolescents use mobile phones … they will …” and “when many individuals …, it causes …”. Most ideas remain understandable, but some grammatical errors occur. For example, “science help us” needs subject–verb agreement, while “science created” and “science brought” use past tense where the general present is more suitable. There are also errors in articles and number, as in “a distinct members,” and in the passive construction “its drawbacks cannot ignored,” which needs “cannot be ignored.” The sentence about digital tools also has a faulty verb pattern. Review agreement, tense consistency, articles and passive forms, while continuing to use varied sentence structures.
