1985年至2010年中国的食品消费

The response covers all three series, gives generally reasonable figures and notes the final equality of salt and meat. Its overview identifies rankings and endpoints but omits the main directions. The period after 1995 is miscounted as ten years, and the description of meat obscures the plateau after 2005.

The introduction, starting figures, subsequent changes and final overview create a clear sequence. Some linking is mechanical: "However" at the start of the trend paragraph implies a contrast with the initial figures that is not established, while "In contrast" would better link falling salt consumption to rising meat consumption.

Vocabulary is flexible enough for the task with terms such as 'fluctuated', 'climbed steadily', and 'downward tendency', despite some imprecise collocations like 'grew up gradually' and 'related figure'.

A good range of structures is demonstrated, including relative clauses and participial phrases such as 'peaking at 850 grams', with only minor errors that do not impede meaning.

The response selects the main trends, the 1995 fish dip and the final equality of meat and salt, with a clear overview and sufficient length. However, saying meat increased throughout the period overlooks its plateau from 2005 to 2010; giving the fish dip a value would also improve support.

The introduction, category-based detail and final overview follow a logical sequence. A concluding overview works here. The lead-in "From the graph we can see" could be more direct, and "However, this" could connect the low starting level to the subsequent rise more explicitly.

Vocabulary is flexible and appropriate for describing trends, using items such as 'dipped', 'rose steadily', 'consistent drop', and 'stood at', with no noticeable errors, though the range is solid rather than wide.

Structures are varied and generally well controlled, including the concessive clause "Although it dipped in 1995" and the reduced clause "while at a relatively low level". Comparisons and past-tense trend descriptions are clear, with no substantial grammatical error evident.
