prep2-132 关于than比较疑问

132.
            (31781-!-item-!-188;#058&006523)

A study published in the British Medical Journal showed that women who ate nuts more than five times a week were about one third less likely to suffer from coronary heart disease as those who ate no nuts at all.

(A) as those who ate

(B) as women who ate

(C) as those eating

(D) than women eating

(E) than were those who ate

答案是E， 当时在DE犹豫，根据分词比定从简洁，所以选了D，结果错了

大家指点一下，为什么D是错误的吧，3x！

呵呵，平行最大。

 women   who ate nuts more than five times a week were （about one third less likely to suffer from coronary heart disease ）than   were   those who ate no nuts at all.

E 选项最平行。。。

而且定从和分词修饰有一个范围的差别。请参照 OG10SC 第一题。

nice job~

此外，我觉得还可以从主语比较vs.宾语比较的角度看这道题

可参考：http://forum.chasedream.com/dispbbs.asp?BoardID=23&replyID=983810&id=103101&skin=0

我的疑问是：

为什么E选项用than were those who ate

were提前的情况不应该是有否定词，倒装才会出现这种情况么？

请NN指教！

是么？那我可不可以这样理解：more...than, as...as中，肯定句助动词是否倒装都可以；否定句一定要倒装。对吧？
