引导表语从句并作表语从句的主语的词有哪些,只有what吗谢谢
如The art centre is ____ used to be a factory ,where tractors were made.为什么不用that和which呢
又比如，He finds his daughter is different from _____ she was five years ago.填what还是who呢
答
通常是这三个：that 、as if、whether~这是最经常出现的!
（其实分得细一点,从属连词：that、whether、if……
连接代词：waht、who、which、……
连接副词：how、when、……）He finds his daughter is different from _____ she was five years ago.填what还是who呢选 who 哦通常 what 是在句子中充当一定成分的，而后面的句子she was five years ago 是一个完整的句子，不需要带刺充当任何成分！ 而选who 是因为前面的 ……from 后缺一个宾语~所以who 啦~呃，答案选what呢，five不是年龄，而是五年前，所以句子不完整吧
