⼆、⽤法说明
(1) 这样⽤的what相当于“先⾏词+关系代词”，所以其前不能有先⾏词：
你喜欢什么就拿什么吧。
正：You can have what you like. / You can have everything (that) you like.
误：You can have everything what you like.
(2) 有时what 可⽤作限定词，其后修饰⼀个名词：
I gave him what books I had. 我把我所有的书都给他了。
美女喜欢帅哥
He gave me what money he had about him. 他把⾝边带有的钱全给了我。
(3) What 后的名词可以是复数名词或不可数名词，但通常不能是单数可数名词：
误：I gave him what book I had.
(4) What后接不可数名词时，有时可有little修饰。注意区别：what+不可数名词=所有的都，what little+不可数名词=虽少但全部。如：
I spent what time I had with her. 我所有的时间都是与她⼀起度过的。
I spent what little time I had with her. 我仅有的⼀点时间都是与她⼀起度过的。

what为什么不能引导定语从句
that可以引导定语从句，⽽且是定语从句引导词中的顶梁柱，它在定语从句中要充当成分，通常作定语从句中的主语、宾语。同时that也可以引导名词性从句，在名词性从句中that 不充当成分。但What不可以引导定语从句。它只可以引导名词性从句，在句中相当于what =all that ,what 在名词性从句中充当成分，常常作主语、宾语和表语。
简单说，what引导的从句是名词性质的，⽽that 引导的定语从句是形容词性质的。所以，what不可能引导定语从句。
Eg: 17).All _____I want to know is what he meant .
A. that
B. which
C. what
