2015年GCT考试英语语法串讲之复合从句3

2014-02-25 14:30:29来源:233网校

  重要考点

  1 限定性定语从句中,关系代词做宾语时可以省略

  2 当先行词是

  *all, something, nothing 等不定代词时

  *first, last, only, few, much, some, any, no 等词修饰时

  *形容词最高级修饰时

  只用that不用which

  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

  引导限制性定语从句和非限制性定语从句

  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

  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.

  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.
