Question

定语从句中which和that的区别,as和that的区别

Answer 1

选 with which
不用that的情况 ,用which的情况
a) 在引导非限定性定语从句时.
The tree,which 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..
e) 先行词既有人,又有物时.
举例：
All that is needed is a supply of oil.
所需的只是供油问题.
Finally,the thief handed everything that he had stolen to the police.
那贼最终把偷的全部东西交给了警察.
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.
