West Park 中学自1950年以来的变化

The overview identifies the main additions and removals, and most features are covered. However, linking the reduced playground to the 1980 science-block addition confuses the timing: the playground remains unchanged in 1980 and becomes smaller in 2010. The response is slightly under the required length.

Ideas are organised chronologically with simple linking devices, but progression is somewhat mechanical and a few sentences, like the houses paragraph, are choppy and under-developed.

Vocabulary is generally adequate for describing map changes, with some flexibility (significant alterations, substantial changes), though word choice lapses such as 'abridged' for the playground reduce precision.

A range of structures is attempted, including passives and relative clauses, but frequent errors such as the comma splice in the farmland sentence and 'there were built science block' limit accuracy.

The response covers the three dates and correctly describes the science-block addition and later playground reduction. The overview identifies only the unchanged road clearly, because 'they were eradicated' has no clear referent. The separate replacements of the houses and farmland also need more precise description.

Progression is broadly clear with logical staging by year, but referencing breaks down, notably the ambiguous 'they were eradicated' in the overview, and some linking is mechanical.

There is a sufficient range of change-related vocabulary such as 'eradicated', 'substituted' and 'extension', though slips like 'car pack' and imprecise phrases like 'left-hand side of the town' reduce precision.

Complex sentences and relative clauses are used with reasonable control. The expression 'the location ... was situated' is redundant rather than an agreement error, while 'since it was constructed ... to the year 2010' is an awkward time construction. The unclear pronoun in the overview also weakens clarity.

The report provides a clear overview and accurately covers all three dates, including the car park's expansion and the sports field's relocation. It is slightly below the 150-word minimum, but the main changes are identifiable; the final layout could be compared more explicitly.

The response is logically organized with a clear overview, chronological paragraphing, and effective cohesive devices such as 'By 2010' and 'Throughout these shifts'.

Vocabulary describes changes effectively, including 'replaced', 'expanded' and 'remained in their original positions'. However, 'demolished' is appropriate for the houses rather than farmland, which was converted to another use.

A good range of structures is used accurately, including passive constructions, participle clauses ('causing the sports field to move'), and complex tense control across time periods.
