非限制性定语从句考点归纳:
as 和which引导非限制性定语从句, 代替整个主句。
1. As everyone knows, China is a country
with a long history. 众所周知,中国是一个历史悠久的国家。
2. She is a teacher, as is clear from her manner. 她是个教师, 这一点从她的举止可以清楚地看出。
Examples:
3. He missed the show, which was really a great pity. 他错过了演出,这真是很大的遗憾。
4. He invited me to dinner, which made me very happy. 他请我吃饭,这使我很高兴。
Conclusion
1. as 和which在引导非限制性定语从句时, as和which可代替整个主句,相当于and this或and that。这两个关系代词都可指代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。
2. as和which引导非限制性定语从句的不
同之处在于:
(1) as 引导的定语从句可置于句首,而which引导的定语从句不可放在句首。
(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;若从句中的谓语为行为动词,则从句中的关系代词只能用which。另外,as引导非限制性从句,常带有“正如”的意思。
