3 非限定性定语从句只能用which 不用that
非限制性定语从句中只能用which,可以指代前面的一个词,也可以引导从句修饰前面的整个主句,代替主句所表示的整体概念或部分概念。在这种从句中,which可以作主语,也可以作宾语或表语,多数情况下意思是与and this 相似。例如:
He succeeded in the competition, which made his parents very happy.
他比赛获胜,令他父母十分欣慰。
4 As在定语从句中的用法
1)引导限制性定语从句和非限制性定语从句
(1)as多与such 或the same连用,可以代替先行词是人或物的名词。
such… as; same…as
It wasn’t such a good dinner as she had promised us
(2)as 也可单独使用,引导非限制性定语从句,作用相当于which。例如:
The elephant’s nose is like a snake, as anybody can see.
2)As引导的非限制性定语从句的位置
as引导的非限制性定语从句位置较灵活,可以位于主句前面.中间或后面,一般用逗号与主句隔开,但which所引导的非限制性定语从句只能放在主句之后
As we all know, Taiwan is a part of China.
Water consists of hydrogen and oxygen, which (as ) is known to all.
5 做介词宾语时,如介词位于关系代词前一般用which 或whom, 如介词位于句末,也可使用that,且可省略。
The earth on which we are now living came into being long, long ago.
The earth (which/that) we are now living on came into being long, long ago.
6 误区
That was the time that/which I still remember today.
That was the time when(at which) he came.
That is the factory that/which we are going to visit.
That is the factory where(in which) my brother works.
