高中英语重点知识点定语从句的用法
1、as, which 非限定性定语从句
由 as, which 引导的非限定性定语从句，as 和 which 可代整个主句，相当于 and this 或 and that。As 一般放在句首，which 在句中。例如：
As we know, smoking is harmful to one's health.
The sun heats the earth, which is very important to us.
注意：as 和 which 在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：
(1) as 引导的'定语从句可置于句首，而 which 不可。
(2) as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词，若为行为动词，则从句中的关系代词只能用 which.。
2、 先行词和关系词二合一
Whoever spits in public will be punished here. (Whoever 可以用 anyone who 代替)
3、 what/whatever; that/what; who/whoever
1)what = the thing which; whatever = anything
What you want has been sent here.
Whatever you want makes no difference to me.
2) who= the person that whoever= anyone who
(错)Whoever robbed the bank is not clear.
(对)Who robbed the bank is not clear.
3) that 和 what
当 that 引导定语从句时 ,通常用作关系代词,而引导名词性从句时,是个不充当任何成分的连接词。宾语从句和表语从句中的 that 常可省略。What 只能引导名词性从 句, 用作连接代词，作从句的具体成分，且不能省略。
I think (that) you will like the stamps.
What we need is more practice.
4、 关系代词 that 的用法
1)不用 that 的情况
a) 在引导非限定性定语从句时。
(错) The tree, that is four hundred years old, is very famous here.
b) 介词后不能用。
We depend on the land from which we get our food.
We depend on the land that/which we get our food from.
2) 只能用 that 作为定语从句的关系代词的情况
a) 在 there be 句型中，只用 that，不用 which。
b) 在不定代词，如：anything, nothing, the one, all, much, few, any,little 等作先行词时，只用 that，不用 which。
c) 先行词有 the only, the very 修饰时，只用 that。
d) 先行词为序数词、数词、形容词最高级时，只用 that。.
