问题
选择题
The room, although_________ to be kept locked, was often left open.
A.supposing
B.supposed
C.to be supposed
D.having supposed
答案
答案:B
题目分析:考查状语从句的省略:句意:这个房间虽然应该一直锁着,但总是开着。完整的句子是:The room, although it is supposed to be kept locked, was often left open.当主从句的主语一致的时候,可以省略从句的主语和be动词,选B。
点评:当状语从句的主语与主句的主语一致,且状语从句中有系动词be的时候,可以把状语从句的主语和be动词一起省略。如果状语从句中有it is的时候,it is 也可以省略。
