3、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
4、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 o
5、ut the production plan.A. Which B. When C. What D. As (2004年江苏)答案解析:此题中,as 引导非限定性定语从句,as 在句中作主语,“就象往常一样,我们制定了生产计划。” which 虽可以引导非限定性定语从句,但不能放在首位,也没有“就象。,正如。”之意,所以选D。3He is such a lazy man _ nobody wants to work with _.A. that; B. as; him C. whom; him D. as; (陕西模拟)答案解析:本题考察as 引导的限定性定语从句,固定搭配为suchas, a
