關係代詞which和as的區別 #四六級、考研英語精華#

(1)位置上,as可放在句首、句末,也可放入主句中;which一般放在主句之後(有時也可用as):

As we all know, reading is very important.

Reading is very important, which we have already known when we were very young.

(2)意義上,as有正如、按照、正像之意,一般用在肯定句中;which可用於含肯、否定意義的句子中:

He failed in the exam again, as was expected.

He failed in the exam again, which was unexpected.

(3)當定語從句所修飾的主句內容是謂語動詞的對象時,常用as,如:

Jack was admitted into the university, as we had expected.

(4)固定結構,用as:

as has been said before as often happens

as is well known as we all can see

the same...as such...as

(5)當關係代詞代表主句引起的結果,又做主謂賓補(SVOC)結構中的主語時,多用which:

He passed the exam, which made him delighted.

(6)在從句中作介詞賓語時,用which,如:

They went to the zoo, after which they saw a film.

(7)在從句中代表主句中的謂語的整個概念時,常用which,如:

He can write a letter in English, which I cannot.

(8)指代主句中某一名詞時,多用which,如:

Beijing, which he was born, is our capital.

(9)代替主句中的形容詞時, 常用which,如:

Lily thought me clever, which she herself was.
