2.___ impressed the vistors was ___ the workers made with their hands.
A.What ,that B.That ,that C.What,what D.That ,what
答案是:C
为什么不能选B?that可以做主语,宾语吗?
请详细说明.谢谢!
只有what可以引导主语从句.that可以做宾语,但不能做主语.但是如果是一个完整的句子做主语,前面要用that引导.例如:
That the beautiful flowers are hers is out of question.那漂亮的花是她的是毫无疑问的.
但在这个句子中,主语是____impressed the vistors,不是一个完整的句子,缺成分,必须用what.
