OG11 76 help...

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

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

问题:

1. as many as  

是用在肯定句中, 在否定句中, 也可以用 so many as. 为啥 so many as 在这里是错的呢?

2. 如果将had该成did, 是不是也可以呢?

錯的應該是"had"的問題歐.....

不能用did,因為助動詞代替原題動詞,原題是過去完成式ㄚ....

对于1,理论上讲必须要出现not 才是so much as

不过最近遇到GWD一道SC,出现了not也用的as much as

never只是一个具有否定含义的副词，所以它的出现不是否定句，记住这个就可以了。did是可以的，但是不出该动词也不为过。

支持，是这个理。

GMAT中间只有no和not两个否定词。no和not出现在并列句中用or，不用and。但是never出现在并列句中还是用and。
