体重上升与体能下降的原因及对策

The essay addresses both causes and solutions with a relevant position and some developed support, but ideas such as the genetics point remain unevenly developed and the conclusion is partially obscured by error.

Paragraphing is logical and cohesive devices are used throughout, though some links like 'Consequently' and 'Alternatively' are mechanically or inaccurately applied.

There is adequate range with some apt collocations such as 'sedentary lifestyle', but idiom misuse ('get a victim', 'icing on the cake', 'is used ostensibly') and wordiness reduce precision.

A mix of simple and complex structures is attempted, but frequent errors in articles, agreement ('making a persons fat'), and clause construction repeatedly affect accuracy without fully blocking meaning.

The response addresses both parts of the question fully, presenting relevant causes and measures with a clear position, developed ideas, and examples such as public health campaigns and gym construction.

Ideas are organized logically with clear paragraphing and linking devices, though some cohesion is imperfect, as in flawed referencing and connective use such as 'tackle with them' and the trailing 'which' clause.

Vocabulary is adequate for the task with some appropriate items like 'ready-to-eat meals' and 'raise awareness', but noticeable word-form and collocation errors such as 'loss in nutrients', 'dependent on', and 'passed through generations' reduce precision.

A range of structures is attempted, but frequent errors in verb form and agreement, such as 'will discussed', 'could possibly leads', 'increased investment', and 'in every countries', obscure accuracy though they rarely block meaning.

The response addresses both the causes and the measures directly, presents a clear position, and supports its main ideas with relevant examples, though the treatment remains somewhat narrow, focusing on only one cause and one solution.

Ideas progress logically across well-organised paragraphs with consistent referencing and clear cohesive devices, but the essay's frame feels somewhat mechanical and the introduction previews information unnecessarily.

Vocabulary is wide and ambitious, with natural collocations such as knock-on effects and over-reliance, though a few choices like sustenance and wellness occasionally sound slightly unnatural or imprecise.

A wide range of complex structures is used with good flexibility and control, and errors, such as the awkward many people starting a healthier regime, are minor and do not impede communication.

The response addresses both causes and measures clearly, develops each idea with explanation, and maintains a consistent position throughout, though support is sometimes general rather than concrete.

Ideas are organised into coherent paragraphs with logical progression and varied cohesive devices, though some linking phrases are used slightly mechanically.

The response shows a wide vocabulary with attempts at less common items, but occasional unnatural or inaccurate word choices reduce precision.

A wide range of complex structures is used with generally good control and frequent error-free sentences, with only minor lapses in naturalness.

The response addresses both causes and solutions with a clear position and relevant supporting examples, though some ideas, such as the dietary cause, are developed unevenly and focus mainly on weight rather than overall health.

Ideas progress logically across well-organised paragraphs with a range of cohesive devices, although linking within paragraphs is occasionally mechanical, such as the abrupt contrast opener in the second paragraph.

The response uses a good range of topic-appropriate vocabulary with some natural precision, including phrases like 'sedentary lifestyle' and 'exacerbated', with only occasional awkward collocations such as 'carbohydrates are not burned up'.

A variety of complex structures, including conditionals and relative clauses, are used with good control, with occasional minor slips such as 'one of the main causes ... is because' and 'more likely to be sat'.
