定语从句中的介词问题

定语从句中的介词问题

形容词从句中的介词如何处理，大致可分三种情况。

1.属于: of which/whom = whose

The family lived in an old house.

The roof of the house had fallen in.

先行名词以“of +原词”、或“原词’s” 形式带入从句。分别对应关系词为of which和whose+名词。

I had many false friends at that time.

One of them betrayed me. （背叛）

先行名词以“of + 原词（人）” 形式带入从句。对应关系词of whom。

【注】who和whom唯一区别是——前有介词、后接whom。

2.时空: 介+which =where/when

Lin’an is a small city.

I was born in that city.

先行名词以“in + 原词（地点）” 形式带入从句。对应关系词in which或where。（我们也可以理解为：先行名词还是原词带入，只是因为介词提前了，所以用which）

【注】that不能代替which的两种情况：1、介词后；2、非限定从句、先行词为前面整个事件（句子）。

3.依此类推：基本原则是用关系词代替先行词，不要打扰介词！

The person should be here soon.

I'm doing the project with him.

先行名词以原词形式带入从句、with提前，只能用whom。

I’d like to thank my father.

I would not have succeeded without his support.

先行名词以“原词’s” 形式带入从句, 前面原本就有个介词without。

His first job is in a big bank.

He learnt a lot of information about financial management from the job.

先行名词以原词形式带入从句。前面原本就有个介词from。

【技巧小结】

1.无论题目如何复杂，基本原则不变，即：关系词代替先行名词！

2.先行名词在原句中的作用：原词、属格（of型或“‘s“型）、介词宾语。

3.注意that和which、who和whom的适用条件区分。
