从og253和og266看助词的使用

253. Analysts blamed May's sluggish retail sales on unexciting merchandise as well as the weather, colder and wetter than was usual in some regions, which slowed sales of barbecue grills and lawn furniture.

A  colder and wetter than was usual in some regions, which slowed

B. which was colder and wetter than usual in some regions, slowing

答案是B

og指出，A中有这样一个错误：usual前面的was应该省去。

我排除这个选项是觉得than usual是习惯用法，并没有觉得有什么语法错误。

再看下一个

266. In a  recent poll, 82 percent of the public favored a Clean Air Act as strong or stronger than the present act.

C. at least as strong a Clean Air Act as is

E. a Clean Air Act at least as strong as

答案是E

当然E选项跟原句的中心更为接近。og认为C最后的is多余。

我在做的时候，认为at least as strong as the present act is. 恰恰是因为E没有is才排除了E。而且C选项的结构也是正确的。

这两道题的省略应该怎样解释呢？尤其是266题。

大侠们指教阿

谢过

253.  that (it was) usual

266. 82% favored an Act as strong as the present Act.

        是宾语互相比较，不是主语互相比较，所以不需要补出动词。

        在主语互相比较时才要尽量补出动词，不出比不补出好；但补错了也不对。

OG说In C and D, is shouldbe dropped. Even with revisions, these choices are more wordy and awkward than the best answer.,想问C项去掉is后,为什么仍然不如E好?

我想问一下，我看了你的解释，你的意思是：

the weather, colder and wetter than （the weather was) usual in some regions,

我觉得你后面这样补全后，就变成（the weather was) usual in some regions

可是这句话是什么意思呢？好像不太正确哦：）

是不是应该补充为：（the weather which was) usual in some regions

是不同地区waether之间的对比。

请指教，欢迎其他xdjm一起讨论：）

感觉比较对象是不同地区的weather.那上面的比较句到底应该怎么补呢？：）

nn帮忙！：）谢谢！：）
