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)

Science is vital to enhancing people's lives in today's fast-paced society. Science improves our lives, but its main goal should be more than that. Instead, it should include social advancement and environmental sustainability. I totally agree that science will further improve people's lives.

Science has made incredible advances that have greatly helped humanity. Medical advancements have improved the quality and length of many people's lives. Science also makes advanced-level vaccinations for serious diseases, while surgical advances have made surgeries safer and more successful. People can easily trust them, and treatments are also cheaper.

However, science should look further than individual well-being. It should address societal issues and long-term implications. Climate change and sustainable energy production are global concerns that demand scientific action. More importantly, nowadays science should aim more towards the future. The future of future generations should be the goal.

On the other hand, the government should take some steps to control the misuse or unexpected harm. Researchers must be aware of the hazards of their discoveries and prioritise ethical issues. For instance, genetic engineering, artificial intelligence, and new technology must be addressed, and well-being should be balanced.

Science has greatly developed our crops. Food production has the potential to increase and reduce hunger. Thus, science should promote sustainability and safety in addition to enhancing lives. This could help many farmers and poor people afford to buy food. The government should have some strict rules for using limited technology.

In conclusion, research should be further improved for better future lives. Science should address societal concerns, prioritise environmental sustainability, and consider ethical consequences. By doing so, it may genuinely improve our potential and benefit humanity and our planet.

Task Achievement / Task Response — Band 6.5

The response addresses the prompt by taking a clear position that science should encompass more than just individual well-being, including social and environmental goals. The ideas are relevant and generally well-supported, such as the mention of medical advancements and climate change. However, some points are slightly under-developed; for instance, the paragraph regarding government regulation feels a bit disconnected from the core argument about the 'aim' of science. While the position is consistent, the development of the argument could be more cohesive to fully reach the higher bands. Overall, the response covers all parts of the task effectively.

Coherence and Cohesion — Band 6.5

The essay is logically organized with a clear introduction, body paragraphs, and a conclusion. Each paragraph has a central theme, such as medical benefits or environmental concerns. Cohesive devices like 'However', 'On the other hand', and 'Thus' are used to link ideas, although some transitions feel slightly mechanical. The progression of ideas is generally clear, though the link between the government's role and the primary goal of science could be strengthened to improve the flow between paragraphs. Paragraphing is used appropriately to separate distinct points.

Lexical Resource — Band 6.0

The vocabulary is adequate for the task and allows for clear communication. You use some topic-specific terms like 'genetic engineering', 'sustainable energy', and 'environmental sustainability'. However, the range is somewhat limited, and there is a tendency to repeat simple phrasing such as 'improve people's lives' or 'science should'. To reach a higher band, you should aim to incorporate more sophisticated collocations and a wider variety of synonyms to express complex ideas. There are no significant spelling or word-choice errors that impede meaning.

Grammatical Range and Accuracy — Band 6.0

The essay demonstrates a mix of simple and complex sentence structures. You show control over basic grammar, and most sentences are error-free. There are some minor issues with phrasing, such as 'Science also makes advanced-level vaccinations', which is slightly unnatural. While you attempt complex structures, they are sometimes repetitive in their construction. The punctuation is generally accurate, and the errors present do not interfere with the reader's understanding. To improve, try to vary your sentence beginnings and use more complex subordinating conjunctions to link your ideas more fluidly.
