he is not the man _he used to be 空里填what和that都可以吗?
问题描述：
he is not the man _he used to be 空里填what和that都可以吗?
答
what不能引导定语从句，你如果想用what，这个句子应该改成he is not what he used to be，what引导表语从句。
答
that
he is not what he used to be
he is not the man that he used to be
答
不可以的,只能填that的,因为前面已经有了the man这个先行词,填that做定语,而如果要填what的话,这句话是这样子的：He is not what he used to be,这样子后部分构成的是有what构成的标语从句.
