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)
Some people believe that the most important purpose of science should be to improve the quality of human life. While scientific advancements have undeniably brought immense practical benefits, I disagree that this is the sole or definitive aim of science. In my opinion, the pursuit of pure knowledge and the preservations of the natural world are equally vital objectives.
On the one hand, a major goal of science is undeniably to enhannce human well-being. For centuries, scientific research has focused on solving practical problem to make life safer, healthier, and more comfortable.The development of the vaccines, antibiotics, and surgical techniques has successfully eradicated deadly diseases and extended life expectancy. Engineering and physics have give to the rise to the internet, modern of transport, and automation, making daily life highly convenient.
On the other hand, limiting the scope of science strictly to human convenience overlooks its broader, fundamental purposes. First, science is driven by basic curiosity and the desire to understanding the universe. Fields like astrophysics, theoretical physics, and evolutionary biology may not to offer immediate practical benefits to our daily lives, yet they expand human consciousness and answer fundamental questions about our existence. Second, a crucial aim of the modern science is environmental conservation. Research into climate change, ecologies, and renewable energy focuses on protecting the planet and other species, which is an objective that transcends immediate human utility.
In conclusion, while upgrading human living standards is a primary and highly visible benefit of scientific discovery, it should not be viewed as its only major goal. Science must also encompass the pursuit of raw knowledge and the protection of the global ecosystem to remained truly meaningful.

Task Achievement / Task Response — Band 7.0
The response addresses all parts of the prompt, clearly stating a position that disagrees with the idea that improving human life is the sole aim of science. The essay is well-structured, with a clear introduction, two body paragraphs presenting counter-arguments (pure knowledge and environmental conservation), and a conclusion. The ideas are relevant and sufficiently developed, providing specific examples such as astrophysics and climate change research to support the argument. The position is consistent throughout, and the response effectively balances the acknowledgement of the prompt's premise with the writer's own perspective.
Coherence and Cohesion — Band 7.0
The essay demonstrates a logical flow of ideas. Each paragraph has a clear central theme, and the transition between the acknowledgement of practical benefits and the introduction of alternative scientific aims is smooth. Cohesive devices such as 'On the one hand', 'On the other hand', 'First', and 'Second' are used effectively to guide the reader. Paragraphing is used appropriately to separate distinct points. The progression of ideas is clear, and the relationship between sentences is generally well-managed, contributing to a coherent overall argument.
Lexical Resource — Band 6.5
The vocabulary is generally appropriate and sufficient for the task. The student uses some academic collocations such as 'scientific advancements', 'eradicated deadly diseases', and 'transcends immediate human utility'. However, there are minor errors in word choice and form, such as 'enhannce' (spelling), 'give to the rise to' (awkward phrasing), and 'the modern science' (unnecessary article). Despite these minor slips, the range of vocabulary is sufficient to convey precise meanings and demonstrates a good level of flexibility.
Grammatical Range and Accuracy — Band 6.0
The essay uses a mix of simple and complex sentence structures. While there is good control over complex sentences, there are several grammatical slips, such as 'solving practical problem' (should be plural), 'desire to understanding' (should be 'understand'), and 'may not to offer' (incorrect verb form). Additionally, there is a minor error in 'to remained' (should be 'to remain'). These errors are non-systematic and do not impede communication, but they prevent the response from reaching the highest band for accuracy.
