建筑底层平面布局的变化

The response covers all three periods with a clear overview and logical sequencing. Some final-stage locations and room footprints need greater precision: the office is above the lower-right flower area, and gift cards occupy only part of the former living room. The bathroom comparison could also include the former secretary’s office.

Ideas progress logically through clear stage-by-stage paragraphing, with cohesive devices such as 'Furthermore', 'while', and 'Moreover' used naturally to link changes.

A good range of change-related vocabulary is used, including transformed, converted and expanded. Some wording could be more precise: reconfigured describes the internal bedroom conversion more directly than demolished, and page-relative expressions clarify the final layout.

Sentence structures are varied and generally controlled, combining passive and active forms effectively. Most sentences are accurate, although the overview would express the initial use and subsequent changes more clearly with a from–into sequence.

The response covers all three plans with mostly accurate, relevant detail and comparisons, but the overview only notes the unchanged kitchen and entrance and does not summarise the major functional changes, and a few descriptions such as the flower displays are loosely expressed.

Information is organised logically by time period with clear progression and generally effective linking devices, though some referencing and sequencing phrases are slightly mechanical or imprecise.

Vocabulary provides a useful range for describing change, including converted and renovated, though merged obscures the creation of two separate bedrooms, and erected and gift card storage place are imprecise in this context.

A range of structures, including passives and perfect forms, is used with good control, and errors are occasional and rarely impede meaning.

All key features of the three stages are selected, compared, and sequenced clearly, with a relevant overview, though a few spatial conversions are slightly imprecise against the plans.

Information is organised logically by period with effective cohesive devices and clear progression throughout the response.

Vocabulary is flexible and precise for describing layouts and change, including natural phrases like internal reconfiguration and open-plan design.

A wide range of structures is used with strong control, including varied passive and relative constructions, with only rare minor errors.
