Student answer (Band 5.5)
Most people believe that the imporatant role of science should be to improve peoples life, while i largely agree to this. However, i believe this shoud not be the sole purpose of science.
On one hand, science focuse on human betterment lives for exmple medical field, technology etc. which largly facialitate the human lives. In the medical field discoveries of vaccine, caner treatment, medicien has improved the human life and secure them from the deaths. The recent vaccine develpoment in corona desease tell us how science should be encourage to work for peacefull and heatly life.
On the other hand, scienc e should also focuse on the environmental issue which is not only belkongs to humans. Thye exculsive technology developnment has led our enviroment with big climate issues such as air pollutions, indusrtial pollution which has a braod spectrum effects on humans as well as other living being. Science should also largely focuse on the others thing beyong humans bettrments. A research paper has reported that most of the living organsim in tehe past that was considerd to be benificial for environmrnt and humans are rapidly disappeartd and this has lead a very serious situation to environment ecosystem.
In canslusion, science has broad spectrum applications and it should be make it a robotoc system around human. It should be expanded and reseach to other things arounds us.

Task Achievement / Task Response: Band 5.5
Your position is identifiable: you largely agree that science should improve people’s lives, while arguing it should not serve humans alone. The examples of vaccines and cancer treatment are relevant, and the environmental paragraph adds a related qualification. However, the response only partly develops the task: the environmental point is not clearly connected to what science’s most important aim should be, and the claim about disappearing organisms is difficult to follow or evaluate. The conclusion repeats the idea that science should address wider concerns but does not clearly weigh these aims. The response is also 23 words below the required minimum, which limits the space available to explain and support your reasons. Develop each main reason with a clear explanation and a specific example.
Coherence and Cohesion: Band 6.0
The response has a recognisable overall structure: an introduction, two body paragraphs signposted by “On one hand” and “On the other hand,” and a conclusion. This helps the reader follow the broad contrast between human health and environmental concerns. However, progression within paragraphs is uneven. In the second body paragraph, the move from pollution to disappearing organisms is abrupt, and the relationship between these examples is not made explicit. Some linking is also mechanical, with repeated use of “science should” and “which.” The conclusion introduces the phrase “robotoc system around human,” which does not clearly refer back to the argument. Use clearer links between claims and examples, and make each paragraph develop one central point in a logical sequence.
Lexical Resource: Band 5.0
You attempt vocabulary relevant to the topic, including “vaccine development,” “climate issues,” “industrial pollution,” and “environment ecosystem.” These choices show an effort to discuss science and environmental effects, but the range is limited and many spelling and word-choice errors make parts difficult to understand. Examples include “imporatant,” “facialitate,” “caner,” and “disappeartd”; phrases such as “human betterment lives” and “broad spectrum effects” are also unnatural or unclear. Repetition of “science,” “human,” and “focus” further restricts flexibility. Aim for accurate topic-specific collocations and check spelling carefully. More precise wording would help communicate your ideas without requiring the reader to infer your meaning.
Grammatical Range and Accuracy: Band 5.0
You use some basic sentence patterns and attempt longer structures, for example, “The recent vaccine development in corona disease tell us how science should be encourage…” However, control is limited: errors in verb forms, agreement, articles, and sentence construction occur frequently and sometimes make meaning difficult to follow. In “science focuse on human betterment lives,” the verb form and sentence structure are faulty; “discoveries of vaccine, cancer treatment, medicine has improved” also has problems with number and agreement. Several sentences lack clear grammatical connections between clauses, and punctuation around introductory phrases and examples is inconsistent. Practise building accurate simple sentences first, then combine them using controlled subordinate clauses. Proofread specifically for subject–verb agreement, articles, and singular/plural forms.
