Task Achievement / Task Response — Band 5.0
The response fails to meet the minimum word count requirement of 250 words, which significantly impacts the development of ideas. While you clearly state your position in the introduction, the arguments are underdeveloped and the essay ends abruptly mid-sentence. The examples provided, such as the mention of hepatitis, are relevant but lack the necessary depth and academic tone required for a high score. To improve, you must ensure you fully explore your main points and provide a complete conclusion. The current length prevents a thorough discussion of the topic, leading to a penalty for task achievement.
Coherence and Cohesion — Band 5.5
The essay shows a basic attempt at paragraphing, but the structure is incomplete due to the unfinished conclusion. You use some cohesive devices like 'To begin' and 'Furthermore', but the flow of ideas is often mechanical. The transition between sentences is sometimes abrupt, and the lack of a final, coherent summary makes the overall progression difficult to follow. To improve, focus on using a wider variety of linking words and ensure that each paragraph has a clear topic sentence followed by supporting evidence and a concluding thought.
Lexical Resource — Band 5.0
Your vocabulary is somewhat limited and repetitive. You frequently use simple terms like 'science' and 'people' rather than more precise academic alternatives. There are also issues with word forms and collocations, such as 'science research is more advance' (advanced) and 'dead the hepatitis cell' (kill/eliminate). While the meaning is generally clear, the lack of sophisticated vocabulary and the presence of errors in word choice restrict your score. Try to incorporate more topic-specific terminology related to medical and scientific advancements.
Grammatical Range and Accuracy — Band 5.0
The essay contains frequent grammatical errors that occasionally impede the reader's understanding. Examples include 'It is often claim' (claimed), 'save people lives' (people's lives), and 'mostly people' (most people). Your sentence structures are predominantly simple, with few attempts at complex grammatical forms. Punctuation is also inconsistent, particularly with the misuse of apostrophes in 'equipment's'. To reach a higher band, you need to focus on subject-verb agreement, correct tense usage, and incorporating a wider range of complex sentence structures with greater accuracy.
