Task Achievement / Task Response: Band 4.0

You state a clear position—“I strongly agreed” that science should improve people’s lives—and give relevant examples involving hospital technology, emergency communication, medicines, and your own operation. These points show an understanding of the topic. However, the response addresses the task only partially: the examples are mostly listed rather than explained, and the final point about assisted reproduction is unfinished. The discussion does not develop reasons for why improving lives should be science’s most important aim or consider the scope of that claim. The response is also 106 words below the required minimum, leaving too little space to develop and support your ideas. Expand each example and connect it explicitly to your position.

Coherence and Cohesion: Band 5.0

There is some basic organisation: the opening gives your view, the next section offers examples, and “another good example” signals a further point. This gives the reader a general sense of direction. However, progression is limited, and several ideas are joined as a list rather than developed in a logical sequence. For example, the sentence beginning “with the use of morden facilities” is a fragment, while the list of drugs, disease prevention, and other benefits is not clearly connected to the preceding claim. Paragraphing and transitions are also limited. Use separate paragraphs for your position, supporting reasons, and conclusion, and explain how each example supports the main argument.

Lexical Resource: Band 5.0

You use some topic-related vocabulary, including “emergency operation,” “scientific intervention,” “specialist,” and “treatment of different diseases,” so the reader can identify your main subject. However, the range is limited and several spelling errors or inaccurate word choices make parts difficult to understand, such as “morden,” “death reat,” “emargency,” and “benafets.” Some phrases are also imprecise, including “improvement of science in the society” and “good scientific intervention.” Aim for accurate, natural collocations and check spelling carefully. More precise terms such as “medical advances,” “mortality rate,” and “emergency care” would help you express your examples clearly.

Grammatical Range and Accuracy: Band 4.5

The response communicates its basic position, but grammatical control is weak and the range of sentence structures is very limited. Errors occur frequently and sometimes make relationships between ideas unclear. For instance, “I strongly agreed” uses an inappropriate tense for a present opinion, and “the improvement of science … has saved” is followed by a sentence fragment beginning “with the use of.” The list about drugs and disease prevention is also not a complete sentence. Capitalisation after full stops is inconsistent, as in “the improvement” and “in many developing countries.” Practise writing complete sentences with clear subjects and verbs, and check tense, articles, and punctuation.
