        2011年08月22日 09時(shí)00分,《今年英語(yǔ):2011年工程碩士GCT英語(yǔ)復(fù)習(xí)輔導(dǎo)專欄9(2)》由出國(guó)留學(xué)網(wǎng)liuxue86.com英語(yǔ)編輯整理.
            3 非限定性定語(yǔ)從句只能用which 不用that
            非限制性定語(yǔ)從句中只能用which,可以指代前面的一個(gè)詞,也可以引導(dǎo)從句修飾前面的整個(gè)主句,代替主句所表示的整體概念或部分概念。在這種從句中,which可以作主語(yǔ),也可以作賓語(yǔ)或表語(yǔ),多數(shù)情況下意思是與and this 相似。例如:
            He succeeded in the competition, which made his parents very happy.
            他比賽獲勝,令他父母十分欣慰。
            4 As在定語(yǔ)從句中的用法
            1)引導(dǎo)限制性定語(yǔ)從句和非限制性定語(yǔ)從句
            (1)as多與such 或the same連用,可以代替先行詞是人或物的名詞。
            such… as; same…as
            It wasn’t such a good dinner as she had promised us
            (2)as 也可單獨(dú)使用,引導(dǎo)非限制性定語(yǔ)從句,作用相當(dāng)于which。例如:
            The elephant’s nose is like a snake, as anybody can see.
            2)As引導(dǎo)的非限制性定語(yǔ)從句的位置
            as引導(dǎo)的非限制性定語(yǔ)從句位置較靈活,可以位于主句前面.中間或后面,一般用逗號(hào)與主句隔開(kāi),但which所引導(dǎo)的非限制性定語(yǔ)從句只能放在主句之后
            As we all know, Taiwan is a part of China.
            Water consists of hydrogen and oxygen, which (as ) is known to all.
            5 做介詞賓語(yǔ)時(shí),如介詞位于關(guān)系代詞前一般用which 或whom, 如介詞位于句末,也可使用that,且可省略。
            The earth on which we are now living came into being long, long ago.
            The earth (which/that) we are now living on came into being long, long ago.
            6 誤區(qū)
            That was the time that/which I still remember today.
            That was the time when(at which) he came.
            That is the factory that/which we are going to visit.
            That is the factory where(in which) my brother works.
