非限制性定语从句(高一)

非限制性定语从句

一．限定性定语从句与非限定性定语从句的区别

二．引导非限制性定语从句的关系代词有as，which，who， whom，whose等，作定语从句的主语、宾语、表语及定语。关系副词有when，where等，作定语从句的状语。关系代词和关系副词在定语从句中一般不能省。

1.who，whom，whose等引导非限制性定语从句时，指代人的普通名词、专有名词等。表示正是或专指先行词等情况。在定语从句中作主语、宾语、定语等。Bob's father，who worked on the project，spent four years in Egypt．

鲍勃的父亲从事这项工程，在埃及度过了四年。

His mother，whom he loved dearly， died in 1818．

他非常爱戴他的母亲，她死于 1818年。

Mr King，whose legs were badly hurt， was quickly taken to hospital．

金先生的腿受了重伤，他很快就被送去住院了。

2.when，where引导非限制性定语从句时，作定语从句的状语。when=and then， where =and there。why不引导非限制性定语从句。

He was quickly taken to hospital，where a doctor wanted to examine Mr King's legs．金先生很快被送去住院，在那里一个医生要检查他的腿。

We will put off the outing until next week，when we won't be so busy．我们把郊游推迟到下个星期，当我们不忙的时候。

3.关系代词as和which 引导的定语从句

as 和which 引导非限制性定语从句时，其用法有相同之处，也有不同之处。具体情况是：

①as 和which都可以在定语从句中做主语或宾语，代表前面整个句子。如：He is honest, as / which we can see. 他很诚实，这一点我们看得出来。

②as 引导的非限制性定语从句可以放在主句的任何地方， which 只可放在主句之后。另外，as 常常有“正如、正像”的含义。如：

As is known to all, China is a developing country. He is from the south, as we can k now from his accent.

③当主句和从句之间存在着逻辑上的因果关系时，关系词往往只用which。如：Tom was late for school again and again, which made his teacher very angry.

④当先行词受such, the same 修饰时，关系词常用as。如：He is not such a fool as he looks.

⑤as 引导的非限制性定语从句一些固定句型：

as has been said before 如上所述

as is well known 众所周知

as was expected 正如预料的那样

as we all can see 正如我们都会看到的那样
