A尺寸上变小了?：The size of A has been reduced by? A消失了：A disappeared / is removed.
A被推倒了：A is pulled down/knocked down/torn down. 恒定表达:

现在让我们再回顾一下之前的地图，是不是一切都变得清晰起来了呢?建议小烤鸭们可以在图边列一个提纲。
例如，一图提纲：car park (中间)garden(西边)shops(东边) post office(东南角落) town hall(北边)。 二图提纲：
carpark——multistory car park (转化表达：替代) garden——city library(转化表达：改造) circular area(加变化：建造)
Norfolk Pine trees (减变化：消失)
post office and town hall (恒定表达：保持不变)
