what he used to be
b.that he used to be
c.what he is used to be
d.that he is used to be
正确答案是a,老师说b选项后面缺少什么,缺少了什么呢?
楼下的,说一下如果我要选b应该在后面加什么,举个例子吧!
恶…我知道应该选a,理由也知道,我只是想知道如果一定要用b的话,应该在b后面加什么?

或者说：tom has change a lot.he is no longer like what,he use to be.这句话的意思是,tom变了很多,不像他以前那样啦,那个what就是指他以前的状态（以前那样）.而that是不充当成分的,你可以说he is no longer like...
