请详细区别一下非限制性定语从句中as与which的用法
展开全部
由as, which 引导的非限定性定语从句,as和which可代整个主句,相当于and this或and that。
区别:
1、as可位于主句的前、中(做插入成分)、后,译为“正如”。
which只能在主句中、后,一般不译。
As we all know , he never smokes .
正如我们所知,他从不吸烟。
2、如果从句是否定句,则只能用“which”引导。
3、非限定性定语从句中出现expect , think , suppose 等表示猜测、想象、预料等时,只能用as
She succeeded in her doing the research work , as we expected .
4、固定搭配:such/the same+as
典型例题
1)Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此为非限定性从句,不能用 that修饰,而用which.,it 和he 都使后句成为句子,两个独立的句子不能单以逗号连接。况且选he句意不通。
2)The weather turned out to be very good, ___ was more than we could expect.
A. what B. which C. that D. it
答案B。which可代替句子,用于非限定性定语从句,而what不可。That 不能用于非限定性定语从句,it不为连词,使由逗号连接的两个句子并在一起在英语语法上行不通。
3)It rained hard yesterday, ____ prevented me from going to the park..
A. that B. which C. as D. it
答案B.
as 和which在引导非限制性定语从句时,这两个关系代词都指主句所表达的整个意思,且在定语从句中都可以作主语和宾语。但不同之处主要有两点:
(1) as 引导的定语从句可置于句首,而which不可。
(2) as 代表前面的整个主句并在从句中作主语时,从句中的谓语必须是系动词;若为行为动词,则从句中的关系代词只能用which.。
在本题中,prevent由于是行为动词,所以正确选项应为B。
As 的用法
例1. the same… as;such…as 中的as 是一种固定结构, 和……一样……。
I have got into the same trouble as he (has).
例2. as可引导非限制性从句,常带有'正如'。
As we know, smoking is harmful to one's health.
As is know, smoking is harmful to one's health.
As是关系代词。例1中的as作know的宾语;例2中,它充当从句的主语,谓语动词know要用被动式。
这是我经过资料整合的结果,希望能帮到你。

as 与which 引导非限制性定语从句的三点区别:
1) As we all know, knowledge comes from practice. 众所周知,知识源于实践。
2) Knowledge comes from practice, as we all know. 众所周知,知识源于实践。
3) He was late again, which made the teacher very angry. 他又迟到了,这件事让老师很生气。
小结;1)位置不同:as用于句首或句中;which只用于句中。
2)含义不同:as----正如;正像;which--这一点;这件事
3)翻译语序不同:as引导的非限制性定语从句先翻译从句,后翻译主句;which引导的非限制性定语从句先翻译主句,后翻译从句。
