在平平淡淡的学习、工作、生活中，大家都跟作文打过交道吧，作文是由文字组成，经过人的思想考虑，通过语言组织来表达一个主题意义的文体。相信写作文是一个让许多人都头痛的问题，下面是小编精心整理的英语语法what与that有哪些区别，欢迎大家借鉴与参考，希望对大家有所帮助。

　　what与that引导名词性从句时有何区别?

请看题：

I think __________ he needs is more practice.

Yes. __________ he needs more practice is clear.

A. what, What B. that, That C. what, That D. that, What

此题应选 C。其余三项均可能被误选。what 和 that 都可以引导名词性从句，但有区别。如：

1. what 引导名词从句时，它在从句中要充当句子成分(主语、宾语等)，而 that 引导名词从句时，它在从句中不能充当句子成分。

2. what 引导名词从句时，它有词义(表示：什么;所的[东西]);而 that 引导名词从句时，它没有词义。

请做以下试题，注意区别 what 和 that。如：

1. ________ you said is different from the thing ________he told us.

A. What, what B. That, that

C. What, that D. That, what

2. I think ________ he said is true.()

But dont forget the fact ________he is a cheat.

A. what, what B. that, that

　　what与that的用法区别

两者均可引导主语、表语、宾语从句，区别是what可在从句中用作主语、宾语或表语，意为“什么”或“所…的”，而that仅起连接作用，本身没有实际意义，在从句中也不充当任何句子成分(引导宾语从句时通常可以省略)：

He doesn’t knowwhatshe likes. 他不知道她喜欢什么。

Whatyou say is quite right. 你所说的相当正确。

I believe (that) he will come to see us. 我相信他会来看我们的。

It’s a pity (that) he didn’t finish college. 真遗憾他大学没毕业。

另外，that 可引导同位语从句，但what通常不用于引导同位语从句：

I had no idea that you were here. 我不知道你在这儿。

　　that与what引导名词性从句的区别

That引导名词性从句只起连接作用，在从句中不作任何成分，无意义，在宾语从句通常省略，但在主语从句、表语从句和同位语从句中均不能省略；what除引导从句外，还在从句中作成分，意为“所……的(东西)”，在含义上等于“名词+that”。如：

1. 用that的例子

That she lacks experience is obvious. 她缺少经验，这是显然的。

The police learned that he wasn’t there at that time. 警察获知他那时不在场。

He realized that she too was exhausted. 他意识到她也精疲力尽。

My idea is that you shouldn’t have left the country. 我的意见是你不应该离开那个国家。

Bob has the mistaken idea that tomorrow is a holiday. 鲍勃错误地认为明天是一个假日。

It was quite plain that he didn’t want to come. 很明显他不想来。

It is natural that they should have different views. 他们看法不同是很自然的.。

2. 用what的例子

What (=The thing that) he said was true. 他所讲的是事实。

It was what he meant rather than what he said. 这是他的原意而不是他的原话。

There’s something in what he says. 他的话有些道理。

Her interest was roused by what he said. 他的话引起了她的兴趣。
