2.引导非限制性定语从句的关系副词有when和where。当先行词指时间时,关系副词用when;指地点时用where。
Chaplin lived the last years of his life in Switzerland,where he was buried in 1977.
卓别林在瑞士度过了他的晚年,1977年他被安葬在那里。
He left his hometown in 1992,when he was only 12 years old.
他于1992年离开家乡,当时他只有12岁。
3.限制性定语从句与非限制性定语从句存在许多不同之处,主要有以下几点:
(1)引导词不同:关系代词that,关系副词why均不可以引导非限制性定语从句。
(2)非限制性定语从句与主句的关系不像限制性定语从句那样紧密,即使去掉,主句的意思依然清楚完整。它与主句之间通常用逗号隔开,译成汉语时,通常不译作定语,而是译成与主句并列的句子。
I have two foreign teachers,both of whom are from America.
我有两个外教,他们都来自美国。
The foreign teacher who comes from America teaches us literature.
从美国来的那位外教教我们文学。
(3)非限制性定语从句的引导词无论在从句中作什么成分,均不可省略;而在限制性定语从句中,作宾语的关系代词可省略。
This is the man (that/who/whom) we are talking about.这正是我们正谈论的那个人。
This is the man,whom we talked about just now.
这就是那个人,我们刚才谈论过的。
(4)在限制性定语从句中,指人时,作宾语的whom可以用who或that代替,但在非限制性定语从句中不可以代替。
He is the very person (whom/who/that) we referred to.他正是我们提到的那个人。
4.as和which引导的非限制性定语从句的区别:
(1)as在非限制性定语从句中作主语、表语或宾语,这个定语从句说明整个句子。as引导的非限制性定语从句既可以放在主句之后,也可以放在主句之前,还可放在主句之中,有"像......一样,正如,正像"的意思。
As we all know,he studies very hard.(as作宾语)
我们都知道他学习很用功。
As is known to all,he is the tallest student in our class.(as作主语)
众所周知,他是我们班最高的学生。
