5分钟解决定语从句
定语从句,顾名思义就是一个从句在整个句子里面做定语,修饰一个名词
我们知道一个句子里面主语和宾语都有可能是名词,
那定语从句也有这两种情况,可以修饰主语,可以修饰宾语。
如果句子结构不清楚,可以先看下面:
和关系副词(where/when/why)来引导。
关系代词在从句中做成分,关系副词不做成分,
判断要用代词还是副词主要看从句里是否缺成分。
比如:This is Shanghai___I visited. (visit是及物动词,后面缺宾语,所以,这里需要用关系代词,可以选择 that/which/或者不填,宾语可以省略,所以可以不填)。
This is Shanghai ___I lived.(live是不及物动词,I live 构成了上面句子结构里的第一种,所以不缺成分,所以这里可以选择 Where 或者 in which, 这里加了in 把live 变成了一个需要接地点的词组 live in,变成了缺宾语,所以可以填in which)
关系代词的用法见下表:
关系副词用法见下表:
As 的用法:
1、such ...as
2、the same....as
3、As is known to everybody,...
原理就这些,下面是几种特殊情况:
不能用That 的情况
1、非限制性定语从句,只能用which/who/whom
——,从句
比如:Mary was much kinder to Jack than she was to the others, which, of course, make all the others upset.
2、in(介词后)+which/whom
比如: she brought with her three friends, none of whom I had ever met before.
不能用which,只能用that的情况
1、修饰词(only/very/the best/the first/all等)+先行词+that
比如:I have read all the books that were borrowed from the library.
2、不定代词作先行词
(something/anything/nothing/somebody/nobody/anybody/all)
比如:I refuse to accept the blame for something that was someone else"s fault.
3、先行词里既有人也有物
比如:We talked about the movies and directors that we knew.
4、which 引导的疑问句里有从句,为了避免重复不用 which用that
比如:which of the two sheep that you keep produces more milk?
定语从句解决了,所以学到后面英语缺的从来不是语法,积累词汇才最重要,
