B
it在when引导的从句中作形式主语,从句的真正主语是the thief broke into the house and stole all his valuable things,that引导主语从句不能省略
这个句子是一个从句又套一个从句的,when及后面的全部又是作know的宾语从句
the man didn't know__the thief broke into the house and stole all his valuable things.
the man didn't know__the thief broke into the house and stole all his valuable things.
A.it was when that B.when it was that C.that it was when D.was it when that
选哪个,为什么?请各位老师赐教.
