1.在名词性从句中,that不做成分,没有意义,一般不省；what在从句中充当主语,宾语或表语,并代表从句中与谓语意思相关的内容.如：
I'm not interested in what you are doing.我对你目前所做的事情没有兴趣.
该句中what做doing的宾语,代表做的事情.what you are doing是宾语从句.
I have mastered what was taught today.我已掌握了今天所教内容.
该句中what做主语,代表所教内容.what was taught today是宾语从句.
Our school is not what it used to be.我们的学校今非昔比.
该句中what做表语,代表以前的样子.what it used to be是表语从句.
That he has won a gold medal is true.= It is true that he has won a gold medal.
他赢了一枚金牌是真的.
该句中that只是引导主语从句,无实在意义,一般不省略.
He made a promise that if i pass the exam,he would buy me a MP4.
他承诺如果我通过考试,他就给我买一个MP4.
该句中that引导同位语从句,无实在意义,不能省略.
2.在定语从句中的被修饰词叫做先行词.引导定语从句的that叫关系代词,代指先行词,可以指人,也可指物,在从句中充当主语,宾语和表语,做宾语时可以省略；where的先行词表具体或抽象的空间或地点,在从句在做状语,不能省略.如：
This is the place where I was born.这就是我出生的地方.
where相当于in the place.
This is the place thatI visited last year.这是我去年参观的地方.
that相当于 the place,做visited的宾语,可以省略.
在定语从句中,在表地点的先行词后使用that和where的区别,可根据其在从句中所做的成分进行分析.
3.what引导名词性从句时可以改为定语从句.
I can't believe what you said.= I can't believe the words that you said.我不相信你所说得话.
I'll do what I can (do) to help you.= I'll do anything i can (do) to help you.我将竭尽所能帮助你.

that what在从句中总是分不清 ,that和what that和where,还有先行词和先行词非怎么分呢? 定语从句中先行词what与that的区别在定语从句中the way做先行词时in which和that的区别 in the early part of this century怎么把先行词和that分开了放在从句中多好如何看是否及物动词还有先行词~定语从句中That,which,where 等的用法 the reason why/that/\ 是否都可做定语从句的先行词和引导词,且在从句中作状语? that'what 和that' where 主语从句可用what引导,同位语从句先行词为that,that可省略英语定语从句中如果先行词是植物和动物,该用that 还是which? 定语从句中先行词指人时,who 和 that 的区别 what和that在从句中怎么用定语从句中先行词为this,these时用which还是that?先行词为that,those呢?
