全球人口过剩的问题与对策

The response addresses both parts of the task with a relevant position and several relevant problems, but ideas are unevenly developed and the solution receives limited support and explanation.

Information is arranged in clear paragraphs with a visible overall progression, but cohesion is often mechanical and linkers such as 'And, also' and 'Even' are used awkwardly.

There is an adequate range of vocabulary for the topic, including phrases like 'scarcity of employment' and 'inversely proportional', though errors such as 'experimenting' and 'take proper initiative and measurement' reduce precision.

A mix of simple and complex structures is attempted, but frequent errors in agreement, article use, and sentence patterns, such as 'Despite governments are trying', somewhat reduce clarity and accuracy.

The response covers both required parts, describing overpopulation problems in undeveloped and industrialised countries and offering a relevant solution, though some ideas are underdeveloped or inaccurately framed, such as the claim that countries want large populations.

Ideas progress in a broadly clear four-paragraph structure, but cohesion is mechanical at times, with overused and misplaced linkers like 'Because', 'And also', and 'By this way' starting sentences.

The response shows an adequate range of topic vocabulary, including 'sanitation', 'famine relief', and 'prevention policies', but there are noticeable word-choice errors such as 'a resounding number of population' and 'economics of the country to depression'.

A mix of simple and complex structures is attempted, but frequent errors in articles, subject-verb and number agreement, and sentence construction, such as 'no countries want it' and 'the increasing of the population', reduce accuracy and sometimes obscure meaning.

The response addresses both required parts with a clear position and relevant, supported ideas, though some solutions are presented briefly rather than fully developed throughout.

Ideas progress logically across clear paragraphs with a range of cohesive devices used naturally, producing a fluent and generally well-sequenced argument.

Vocabulary is sufficiently wide and precise for the topic, with natural collocations such as population explosion and penalised financially, alongside only occasional less ambitious phrasing.

A variety of complex sentence structures is used with good flexibility and control, and errors are rare and minor, allowing meaning to be conveyed consistently.

The response directly addresses both parts of the task, presenting developed problems with concrete examples and multiple plausible solutions, with a clear concluding position, though ideas remain somewhat general rather than fully extended.

Ideas progress logically across well-managed paragraphs with consistent use of cohesive devices, although linking is at times mechanical and predictable.

Vocabulary is sufficiently wide and precise for the topic, with natural collocations such as 'strain on natural resources' and 'informal settlements', but phrasing is occasionally formulaic.

Relative clauses, participial constructions and varied verb forms are used accurately to explain the problems and proposed measures. The writing shows good grammatical control and clear relationships between ideas.

The response addresses the problems of overpopulation and proposes relevant measures for resource use, pollution and food supply. These measures can address the consequences of population pressure without reducing population growth itself. Some explanations remain general, particularly how the agricultural measures would improve food availability.

Ideas are logically organised with clear paragraphing and a range of cohesive devices, although linkers like furthermore and hence are occasionally used mechanically.

Vocabulary is flexible and precise, with natural use of less common items such as coalesce, delineated, and malnutrition, and only very occasional awkward choices like weightage.

A wide range of complex structures is used with generally good control, with frequent relative clauses and subordination, though some sentences are overlong or slightly awkward.

The response addresses all parts of the task with a clear position, relevant problems, and developed solutions supported by concrete examples.

Ideas progress logically across well-managed paragraphs with effective linking, though the organisation is somewhat mechanical and predictable.

The response demonstrates a wide and precise academic vocabulary, including natural collocations such as strain on, family planning initiatives, and mitigate these issues.

A wide range of complex structures is used flexibly and accurately, with only rare minor slips that do not impede communication.
