1997至2012年博物馆各类游客人数

The response gives a clear overview of the contrasting group trends and reports the selected category figures accurately, including the adult peak of 400,500. It does not discuss the 2002 values or quantify the net rise in total attendance, and the interval behind the slight exhibition increase needs clarification.

Ideas progress logically through overview, baseline data, and subsequent trends, with effective use of referencing and cohesive devices such as 'thereafter' and 'this was not the case', though the sequencing is somewhat predictable.

Vocabulary is varied and mostly appropriate, including attendance figures, welcomed and footfall. Some expressions are less precise: visitors witnessed an upward trend makes the people sound like observers, while the four years examined leaves the net change less explicit.

Sentence structures are varied and controlled, using participle clauses and contrastive constructions accurately, with only occasional minor issues that do not impede meaning.

The response presents a clear overview, covers all three visitor categories and the totals, and reports the selected figures accurately. It omits the 2002 intermediate values and total dip, while the lower growth-rate comparison needs a stated measure because absolute and percentage changes differ.

Ideas progress logically across well-organised paragraphs with effective referencing and linking, though a few transitions are somewhat formulaic and one comparative statement is slightly opaque.

Vocabulary is flexible, with effective expressions such as overwhelming majority and experienced a significant rise. The phrase at a much lower rate needs a specified measure, and those of adult age visiting the museum is unnecessarily indirect.

A wide range of structures is used with strong control, including participle clauses, perfect forms, and contrastive constructions, with only rare minor lapses.

The response presents a clear overview of net group growth, the under-15 decline and adult dominance, with well-selected data and comparisons. The 2002 adult count is miscopied as 320,200 rather than 302,200, and the exhibition peak should be limited to the period shown rather than called an all-time record.

Information is logically grouped by time period with effective cohesive devices and clear progression, though occasional phrasing such as 'that for adults' and 'witnessing a 4% decline' is slightly mechanical.

Vocabulary is flexible and precise, with natural terms like 'museumgoers', 'constituting', 'shrunk', and 'all-time high', and only rare awkward collocations such as 'make up the most significant figure'.

A wide range of structures is used with strong control, including complex tense forms, participle clauses, and contrastive constructions, with only rare minor slips such as the missing 'of' in 'an all-time high 42,000'.
