题目

复合句中主句主语和从句主语一致时,请问能否省略主语?
课本原句是：
When asked about the secret of his success,Steven Spielbeg said that he owes much of his success and happiness to his wife and children.
老师说 当是状语从句,而且从句形式是主语+be动词时,能省略主语和be动词,
请问当主句主语和从句主语一致时,不是主语+be动词的形式能省略主语吗?
还有请问是不是只有状语从句能这样省略?名词性从句和定语从句可以省略吗?

答案

你问的是有关英语中的省略现象,这个说起来类别很多不过当前后主语相同或是it时,同时把主语和be省略的现象在状语从句里最多,并且往往是when,while,if,as if,though/although,as,until,whether等连词引导的状语从句里....
