pron.(代词)

what用作疑问代词时,其基本意思是“什么,什么东西,什么事情”,用作疑问句,为特殊疑问句的一个标志。

what作关系代词时,其含意是“所…的事(物)”。可用来引导主语从句,表语从句,宾语从句或同位语从句。当引导主语从句,其所指的名词必定是单数。主语是单数时,谓语动词一般是单数,但有时因谓语动词之后有复数名词,谓语动词也可用复数; what引导宾语从句时,常置于谓语之后,用作表语时,放在系动词之后。what还可引导让步状语从句,意思是“不管…”。还可接动词不定式短语。

what有时候可解释为whatever，表示“不管怎么样”。

I gave him what help I could.
我给他任何我能给的帮助。

what所引导的句子中，判断从句谓语动词用单数还是复数，看what后跟的词是单数还是复数。

What is required is some good books.
第一句中what后跟is，固required后的谓语动词用单数is。第二句中what后跟are，固required后的谓语动词用复数are。

有时，what可同时用于主格和宾格，并且表示两个不同的事物。

I do not know what he is and does.
我不知道他是谁，也不知道他做什么。

What有时候可等同于that，those或 which。

What I am interested in you may not be interested in.
我感兴趣的，你可能不感兴趣。

What既可作疑问代词，也可作关系代词。

He asked me what I wanted. (疑问代词)
He gave me what I wanted.(关系代词)

What在作关系代词时，可表示“下文所讲的话”。

He went, and, what is more surprising, actually won the prize.
他去了，而且更令人惊讶的是，他还获奖了。

and what not表示“以及其他”，使用时在其前面一般至少有两个或两个以上的名词，偶尔可以是形容词。

He sent me books, magazines, newspapers, pictures, and what not.
They were then generally dirty, ignorant, superstitious, and what not.

句式What is he?中，所提问的是他的职业或者身份，回答不可以是人名。

He is a professor of physics.
前两句的回答是正确的，但是第三句不可以。
