as在限制性定语从句中的以用法及as与that的区别.
3个回答

as 可以用作关系代词,在限制性定语从句中 ,多同such 或the same 连用,构成 such.as

和 the same...as结构 .as 的先行词可以是人或物.如

he is not such a fool as he looks.他貌似憨傻 实则不然.

the same ...as 表示同一类的 如 this is the same book as i bought yesterday.

the same...that 表示同一个 如 this is the same book that i am looking for.

不过 有时区别不大 可以互换

如 we drove out of the town by the same road as/that we had entered by.

我们从进城的原路开车出城去.
