为何大学阶段的学习比中小学更难

The response addresses both questions directly, presents a clear position on causes and solutions, and develops main ideas with relevant explanation, though support remains somewhat generalized rather than extended.

Ideas progress logically across clear paragraphs with effective linking devices, though cohesion occasionally relies on slightly mechanical connectives and the development within paragraphs stays uniform rather than fully extended.

Vocabulary is sufficiently flexible and precise for the topic, with natural academic collocations such as academic rigor, self-directed learning, and individualized support, and only minor imperfections.

A variety of complex structures is used with good control, including relative clauses, participial clauses and parallel constructions. Errors are rare and do not impede understanding, although two full stops have unnecessary preceding spaces.

The response clearly answers both questions, presents a consistent position, and supports the causes and solutions with relevant examples, though some ideas are developed only briefly.

Ideas progress logically across well-structured paragraphs with clear linking, although transitions occasionally feel mechanical, such as the repetitive use of 'this' and 'the problem mentioned above'.

Vocabulary is flexible and precise in places, with good items like 'pedagogical techniques', 'self-discipline', and 'rigorous discussion', alongside occasional minor imprecision such as 'the activity of high schools'.

Complex sentences are generally well controlled, including relative clauses and contrast structures. Some comparisons and long modifier sequences could be clearer, but meaning remains accessible throughout.

The response directly answers both questions, presenting two clearly developed causes and matching solutions with sustained explanation and a clear concluding position.

Ideas progress logically across well-organized paragraphs, with a range of cohesive devices used naturally and with only occasional mechanical sequencing.

The response uses a wide academic vocabulary, including specialized subjects and individualized support. Precision is weakened by repeated use of grade school for secondary education and a few awkward combinations such as small size classes.

A wide range of complex structures is used with strong accuracy, and the few errors, such as 'result from' in the conclusion, are minor and do not impede communication.

The response directly answers both questions, presents relevant, well-developed causes and solutions, and maintains a clear position throughout, with only mildly general support.

Ideas progress logically across well-organised paragraphs, and cohesive devices are used skilfully and unobtrusively, giving a clear overall progression.

Vocabulary is wide, flexible, and precise, with natural academic collocations such as academic rigour, conducive environment, and tertiary education, and only negligible inaccuracy.

A wide range of complex structures is used with strong control and flexibility, and error-free sentences are the norm across the response.
