定语从句中what和that1
一、引导主语从句
that与what都可引导主语从句，that在从句中不作句子成分，但不能省略。what 在从句中可作主语、宾语、表语等，不能省略。如：
What he said at the meeting was very important．他在会上所说的非常重要。（宾语）
What surprid us is that he did it alone．使我们吃惊的是他一个人做了那项工作。（主语）
That he did it alone surprid us．他独自完成了那项工作使我们感到吃惊。（that用来引导主语从句，在句中不作成分）
二、引导宾语从句
that与what都可引导宾语从句，that在从句中不作句子成分，一般情况下可以省略，但当有两个以上的宾语从句时，只能省掉第一个that。what 在从句中可作主语、宾语、表语等，不能省略。如：

The teacher got angry becau of what the boy had done．那个男孩子做的事情让老师很生气。（what在宾语从句中作宾语）

三、引导表语从句
that与what都可引导表语从句，that在从句中不作句子成分，且不能省略；what 在从句中可作主语、宾语、表语等，不能省略。如：

四、引导同位语从句
that与what都可引导同位语从句修饰表示抽象概念的名词，对所修饰的名词的具体内容进行详细阐述。这类名词有：fact, idea, news, hope, belief, promi, thought, suggestion, pr
oposal等。that在从句中不作句子成分，但不能省略。what 在从句中可作主语、宾语、表语等，不能省略。如：

五、引导定语从句
that可引导定语从句且在定语从句中作主语或宾语，that既可指人也可指物。that在从句中作宾语时可省略。如：

注意：what不能引导定语从句。如不能说：
1．He did all what he could to save the patient．
2．All what he needs is more time．
应将句中的what改为that，或去掉what，还可以将以上两句中的all去掉，但两句的结构发生了根本的改变：句1中的what引导宾语从句，句2中的what引导主语从句。
六、引导状语从句
so...that, hat, so that结构引导状语从句。what不能引导状语从句，但whatever, no matter what可引导让步状语从句。如：
He made such rapid progress in English that before long he could write articles for an American newspaper．他的英语进步很快，不久就能为美国的一家报社写文章了。

一、引导词what与that在引导名词性从句的用法区别引导主语、宾语或表语从句时，what在从句中要充当句子成分;而that引导主语、宾语、表语和同位语从句时，不作任何成分，只起语法连接作用。试比较：
