定语从句which前的介词怎么选

更新时间:2023-04-21 16:54

介词的选择是根据从句的动词决定的,不及物动词后要跟介词

①of which相当于定语whose,后加名词,相当于是一个形容词。

eg:There are many books in the shelf, of which/whose covers are old.

书架上有许多封面陈旧的书。

②,in which相当于疑问词where,是对地点名词的修饰。

如:The book (in which/where there are many stories) in his.

这本有许多故事的书是他的

③on which相当于特殊疑问词when,是对时间的修饰。

如:I will never forget the best time when/on which we enjoyed ourselves.

④,for which相当于疑问词why,是对原因的修饰。

如:I don't the reason why/for which he was late.

我不知道他迟到的原因

⑤at which相当于疑问词how,是对方式名词的修饰

介词➕which/whom引导的定语从句+长难句打卡Day1

“介词+关系代词”引导的定语从句,是定语从句一种介词前置的定语从句句型,介词与关系代词之间存在一种介宾关系。当关系代词在定语从句中作介词宾语时,把介词置于关系代词前,即演变出“介词+关系代词”句型。

例如:

The man who/whom /that you spoke to is a teacher.

=The man to whom you spoke is a teacher.

一、基本构成

1、“介词+关系代词”结构引导的定语从句中,关系代词只能用which(指物)或whom(指人) ,即:介词+which/whom。

(1)The man to whom you spoke is a teacher.

(2)The city in which she lives is far away.

(3)The little girl is reading a book, in which there are many cartoons.

注意:当介词放在关系代词的前面时,用在介词后的关系代词不能省略。

2、在限制性定语从句中,当介词置于定语从句的谓语动词之后时,可用that/which(指物)that/who/whom(指人)作介词的宾语.且此处关系代词可以省略,特别是在口语中。如:

(1) The man (who/whom /that )you spoke to is a teacher.

(2)The city(which/that)she lives in is far away.

注:通常介词放在定语从句中动词后,也可以放在关系代词前面,但有些特殊动词短语搭配不能拆分,介词只能放在动词后,如: look for, look after, pay attention to ,take care of , look forward to, listen to等。

This is the pen that / which you are looking for.

The patient whom she is looking after is her father.

The words that /which we should pay attention to are written on the blackboard.

There are fifty patients who/whom/that we must take good care of.
