二、用法說明
(1) 這樣用的what相當(dāng)于“先行詞+關(guān)系代詞”，所以其前不能有先行詞：
你喜歡什么就拿什么吧。
正：You can have what you like./ You can have everything (that) you like.
誤：You can have everything what you like.
(2) 有時what 可用作限定詞，其后修飾一個名詞：
I gave him what books I had.我把我所有的書都給他了。
He gave me what money he had about him.他把身邊帶有的錢全給了我。
(3) What 后的名詞可以是復(fù)數(shù)名詞或不可數(shù)名詞，但通常不能是單數(shù)可數(shù)名詞：
誤：I gave him what book I had.
(4) What后接不可數(shù)名詞時，有時可有l(wèi)ittle修飾。注意區(qū)別：what+不可數(shù)名詞=所有的都，what little+不可數(shù)名詞=雖少但全部。如：
I spent what time I had with her.我所有的時間都是與她一起度過的。
I spent what little time I had with her.我僅有的一點時間都是與她一起度過的。
