1978年至2008年各年龄组每月看电影的比例

The response covers all four age groups and gives a defensible overview of their net changes. However, it misidentifies the denominator of the 35–49 group's percentage and incorrectly says the 25–34 group stabilised at 80% from 1988 onwards; the older groups' initial declines also need clearer reporting.

Paragraphing is logical with a clear introduction, overview, and detailed body, and cohesive devices are used naturally, though the internal contradiction in the trend narrative slightly disrupts clarity.

Vocabulary is flexible and precise, with sophisticated items such as 'closely followed by', 'rebounded', 'albeit', and 'pronounced patterns', used accurately with no noticeable errors.

A wide range of complex structures, including varied participial and relative constructions, is handled flexibly and accurately, with only very minor lapses.

All four age groups are covered with an overview and relevant comparisons, but the stated period 1984 to 2003 conflicts with the chart's 1978 to 2008 range. The youngest group's decline is also described as beginning in 1998, although its rate remains level until 2003.

The response progresses logically through the age groups with a clear overview and generally effective cohesive devices, though transitions like 'Conversely' occasionally misrepresent the similarity between trends.

Vocabulary is flexible and mostly precise, with phrases such as 'taper off', 'mirrored this trend', and 'age bracket', despite minor slips like 'over then following ten years'.

A wide range of sentence structures, participle clauses, and complex forms is used with strong control and only rare, non-impeding errors.
