作为答案的B选项中so...as的用法，这里不是否定句么？为什么A中用as...as(正确答案是A)

我觉得lz的关注点错了，先看主要的错，B的主谓不一致A and B结构谓语用复数，另外previouly是过去式的标志，而B用了现在完成时

B中have 是不该用，因为执行者是the economy,这个我懂，可是如果A对，我就有点不懂so ....as,与as..as ,的用法了，我正因为这个，一开始就排除了A。。。。。就是搞不懂什么时候as改为so，难道这里不应该？

reginechen

B的主语也不是the economy而是some analysts,这里确实是so...as更好，但是我觉得应该不是correctness的错，所以不能优先考虑，而B中其他的错都是correctness的级别

言之有理，两个名字并列，谓语动词是该用复数，have是作为从句谓语动词，可是还是不明白A，GMAC出题一向严谨，对于喜欢秒题的人确实是很大的挑战，还是希望能把as...as,和so...as的知识给弄懂，是不是否定不一定用so.....as，我就想明白这个，明白了，只要见到错误就可以直接排除 ，节约时间

查了下语法书。。as...as。。。可由于肯定或否定，但so....as，只用于否定，是我自己才疏学浅了。。。。希望不会误导大家

B的错误在suggest。。。had previouly estimated应该是可以的，见TN3-14
