题型：不详难度：来源：

Most American cities are relatively small in terms of population when _____ with Chinese cities like Shanghai and Beijing．

A．compare

B．comparing

C．compared

D．to compare

答案

C

解析

考查省略句。当状语从句的主语与主句主语一致，且谓语动词是be动词的时候，可以把状语从句的主语和be动词一起省略。本题when与compared之间省略了．Most American cities are.同时本题是compare sth to sth的被动语态。句意：就人口方面大部分美国城市与中国的上海北京进行比较的时候，这些城市就相当小了。故C正确。
