英语从句问题
This museum is not ____ it was ten years ago.
A that B when C which D what
选D ,翻译句子,what 的成分,从句的构造,求详解 ,

Answer 1

这个句子里,需要先行词和连接词,而 what 在引导表语从句的时候,就是起先行词+连接词的作用,相对于 the thing that
This museum is not __what__ it was ten years ago.
=This museum is not __the thing that__ it was ten years ago.
至于为什么要 what,那是因为主语是 the museum,是个“物”,所以后面的表语也必须是物.而其他的连接词,都只能引导从句,而没有那个“物”的概念.
