注意:
先行词是时间、地点、原因,用关系副词when、why、where,必须保证它们在定语从句中作状语。如果定语从句缺主语或宾语(意思是定语从句需要一个作主语或宾语的词),那么就必须用关系代词which 或 that。

*which引导的从句只能放在主句之后; as引导的从句,可放在句首、句中或句尾。
as常带有“正如”之意,且已形成固定结构。
常用的句式有:
as is stated above 如上所述
as is mentioned above
正如上面所提到的那样
as is known to all 众所周知
as anyone can see
正如任何人都能看到的那样
as 和which 引导非限制性定语从句的区别
1. Einstein, as is known, is a famous scientist.
2. As is reported, China has become an important country in the world.
3. Taiwan belongs to China, as is known to all.
4. Bamboo is hollow, which makes it very light.
5. My son now goes to the school, which I used go to when I was a child.
6. He didn’t come to attend the meeting, as is expected.
3. as在从句中作主语,从句中的谓语必须 是系动词;而which则不一定。
He is very strict, as is shown in his work.
The man is very learned, as is described in the book.
4. 先行词前有the same, such限定时,关 系词只能用as.
I have the same opinion as you (have).
Don’t read such books as are beyond your ability.
当先行词受the same 修饰时,有时也用 that引导定语从句,但与as引导的定语从句意思有区别。
She wore the same dress as her younger sister wore.
She wore the same dress that she wore at Mary’s wedding.
5.主从之间存在逻辑上的因果关系时,关系词往往用which。
Tom was late for school again and again, which made his teacher very angry.
* The book which is on the desk is mine.
* The books which are on the desk are his.
关于定语从句中的谓语动词性和数的一致问题
1.当关系代词在定语从句中作主语时,从句的谓语动词要与先行词在人称和数方面保持一致。
* She is one of the engineers who are from Germany.
她是这些来自德国的工程师之一。
* She is the only one of the engineers who is from Germany.
她是这些工程师当中唯一来自德国的工程师。
2.当关系代词为one of +名词复数 时,从句的谓语动词用复数形式。如果one前面用the, the only, 修饰时,从句的谓语动词用单数形式。
