标题: OG10-SC-92 过去时和过去完成时

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

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

帮忙解释下。谢谢！

1.as...as

2.主句过去完成时,你只能再选择一般过去时了.

3.so....that这种用法是错误的...

谢谢！我还想问：

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

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

前面用过去完成时，后面为什莫用一般过去时？我看A就是划线部分挺顺眼的。另外：so...as 不对吗？干吗非要用 as...as

1，后面指出了在1986年，是在叙述过去的那件事情。

2，so..as 用在否定句中，as..as 用在肯定句中。

so..as 用在否定句中，as..as 用在肯定句中。

本句是否定句还是肯定句呢？

本句是肯定句, never 代表否定意思，但不是否定句。

只有助动词+not才是英语中的定义的否定句

是的，只有 no 和 not 表示否定句。
