标题: OG 92---关于助动词 [打印本页]

作者: kenlily    时间: 2005-9-22 13:27     标题: OG 92---关于助动词

92. Never before had taxpayers confronted so many changes at once as they had in the Tax Reform Act of 1986.

(A) so many changes at once as they had in

(B) at once as many changes as

(C) at once as many changes that there were with

(D) as many changes at once as they confronted inD

(E) so many changes at once that confronted them in

这道题我第一次选的是A

我的问题是关于比较形式后补出的动词的.

1. 为什么不能把A理解为so many changes at once as (the changes)they had(过去时, 而非过去完成时) in 1986.

2. 在比较结构中, 补出的动词或助动词应该如何判别??以什么为标准呢??

例如本题的正确答案就补出了原动词, confronted.

在对付本题的过程中, 我就把had理解为了have的过去时, 而不是过去完成时.

谢谢!!

1. A: so many changes at once as (the changes)they had (confronted) in 1986.

比较,是实意动词的比较,这里必须补出comfronted,这里从逻辑和in1986上判断,是过去从未有的一个事件和过去一个事件的比较,即过去完成时态和过去时比较,所以A是错误的

2.在比较结构中,但谓语(内容)一致的时候,比较两个主语时,在比较词(than/as等)后,要尽量补出谓语动词,其原则为:

(1)当比较词之前的谓语动词为一般现在时或一般过去时,比较词后应该相应的用do/does/did/is/was/were/are来替代;

(2)当比较词之前的谓语动词由助动词(情态动词)+主要动词组成,则在比较词之后保留此助动词(情态动词)即可;

(3)比较前后的时态不一致:两个比较对象的动作是相同的,但是其发生的时间却不一致

a.比较前是过去时,其后的时间状语暗示了将来的动作,补出助动词will

b.比较前是过去时,其后是过去完成时,补出had

分析本题,前为过去完成时,后为过去时,如果只是补出had,如(3)b.所言,则是过去完成时和过去完成时的比较,则与in 1986明显冲突,应该用过去时,直接补出动词的过去时态即可!
