[求助]麻烦各位NN帮我看看这题啦～

Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than it was in any previous election.

1. a greater proportion than it was

2. a greater proportion than

3. a greater proportion than they have been

4. which is greater than was so

5. which is greater than it has been

答案选的A。想问为什么B不对？比较结构省略原则不是可以只保留介词短语么？

还望高人指点呀！

答案应该选B！

A错，不需要IT WAS。。。

spending ,同位语的比较结构

等价结构sth in。。。than in。。。。就可以了！

看来这题还是挺有争议的...我就很清楚地记得上课笔记里说比较结构中，如果比较的事物是主语，那助动词或情态动词就一定要补全避免歧义，但作宾语就不要。我很想同意楼上的观点，但答案写的是B...唉这是“最新13套”里第一套里的题...郁闷！

这题没争议，

the answer undisputably goes to B

A对不了，想对必须是IT DID而非WAS

答案也只能是B了

one more word

答案不重要，关键是下一道题目要做对

做对的前提是流程要对

流程对的前提是要形成做题习惯

形成做题习惯的前提是你要相信这样的习惯有助于您提高分数

症结来了

您不愿意相信其他的做法

您相信xdf的书（符合您的学习惯性）

anyway

don't be tangling

best regards

但我觉得还是应该有it was的

仔细看这个句子

Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than it was in any previous election.

逗号前的句子只是陈述一个事实，句子主干部分主干是costs accounted for the spending，那么a greater proportion并不能解释the spending，逻辑不合理，所以比较的对象应该是a greater proportion和以前的proportion比。

我也是杀G新手，一点拙见
