As引导的定语从句解析(共3页).doc
精选优质文档-倾情为你奉上As引导的定语从句解析我们知道,定语从句是在复合句中用来修饰主句里面的名词或代词的从句,引导定语从句的一般有关系代词who、whom、whose、which、that 和关系副词when、where、why等。但我们在学习和高考试题中经常会碰到as 引导的定语从句。如2001年全国高考卷:_ is known to everybody, the moon travels round the earth once every month.A. It B. As C. That D. What本题考察as 引导的非限定性定语从句,“正如大家所知”,后面整个句子“月球每月绕地球转一圈” 指代as 做先行词,as 在句中作主语,所以选B。下面就as 引导的定语从句加以归纳并解析:1) as 用作关系代词和关系副词引导限定性定语从句,并在从句中作宾语、表语和状语,构成the sameas, suchas 等结构。例如:I like the same book as you do. (as 作宾语)I shall do it in the same way as you did. (as 作状语)I want to have such a dictionary as he has. (as 作宾语)2) as 引导非限定性定语从句,在句中作主语、表语或宾语,这个定语从句是说明整个句子,可以放在主句之前。例如:As we all know, he studies very hard. (as 作宾语)As is known to all, he is the best student in our class. (as 作主语)常用的这种类似插入语的句式有as is said above, as is known to all, as it is 等。要注意的是,关系代词whom, which, that 在限定性定语从句中作动词宾语和介词宾语,而该介词又位于句末时三个关系词经常省略,但as 一般不省略;which 和as 在定语从句中的区别:which 不能放在句首,而as 可以;as 在句中有“正如,就象”之意,而which 则没有。例题解析:1 The Beatles, _many of you are old enough to remember, came from Liverpool.A. what B. that C. how D. as (2006年天津)答案解析:本题考察as 引导的非限定性定语从句,as 指代的词the Beatles在从句中作宾语,其他词不能引导非限定性定语从句。本句意为“正如许多老人记得的那样,甲壳虫乐队是来自于利物浦。”所以选D。2_ is often the case, we have worked out the production plan.A.
