③关系代词as引导的定语从句，只需记住as“正如”的意思和几个固定句式，
a. 这是一块儿重到没人能举得起的石头。
This is so heavy a stone as no one can lift.
=This is such a heavy stone as no one can lift.
（把句中as换为that，句末需加上it 。This is so heavy a stone that no one can lift it.
对比前句可以发现as=that it，既起到连词作用，又起到代词作用，是一个关系代词。）
b. 众所周知：
as is known to all（正如被所有人知道的那样）
= as we all know(正如我们都知道的那样)
=as everyone knows （正如每个人都知道的那样）
c. as is often the case（正如经常发生的情况那样）
d. as an old saying goes （正如一句老话说的那样）
④ the way作先行词的定语从句，that（关系副词）=in which (来自于in this way)
The way（that=in which) he answered the question was surprising.
他回答问题的方式是令人惊讶的。
⑤抽象地点作先行词的定语从句
occasion(场合) stage(阶段) point（程度，地步）situation（处境）case（案例）等表抽象地点的先行词，关系词用where。

婚姻是一家工作室，在这里丈夫工作妻子购物。（把workshop看作抽象地点）
