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 in(D)
(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!! |
