1.介詞+what 結(jié)構(gòu)有兩種理解:
1).介詞+what+不定式 后者是疑問詞+不定式結(jié)構(gòu),該結(jié)構(gòu)在本質(zhì)上相當于一個名詞(短語),充當介詞的賓語.
如:I'm interested in what to do with this dog.
我對該怎樣處置這條狗很感興趣.
2).介詞+what引導的賓語從句
如:I'm interested in what you will do with this dog.
2.介詞+關(guān)系代詞(what不能做關(guān)系代詞,一般是which/whom,不能用that或who)引導一個定語從句.
關(guān)系代詞一般代指先行詞,在該定語從句中充當這個介詞的賓語.
介詞+關(guān)系代詞經(jīng)?？梢赞D(zhuǎn)換成關(guān)系副詞.
如:This is the city in which I lived last year.
=This is the city where I lived last year.
