虚心请教一语法题

Q28:

Antarctica receives more solar radiation than does any other place on Earth, yet the temperatures are so cold and the ice cap is reflective, so that little polar ice melts during the summer; otherwise, the water levels of the oceans would rise 250 feet and engulf most of the world’s great cities.

is reflective, so that little polar ice melts during the summer; otherwise,

is so reflective that little of the polar ice melts during the summer; were it to do so,

so reflective that little polar ice melts during the summer, or else

reflective, so that little of the polar ice melts during the summer, or

reflects so that little of the polar ice melts during the summer; if it did

C选项：is是不是不能省略？因为and前的并列成分用的动词时are?
              or else是不是不够地道？

本题正确答案是B

首先，省略的想法，是因为看了这道题：
So dogged were Frances Perkins' investigations of the garment industry, and her lobbying for wage and hour reform was persistent, Alfred E. Smith and Franklin D. Roosevelt recruited Perkins to work within the government, rather than as a social worker.

A.and her lobbying for wage and hour reform was persistent,

B.and lobbying for wage and hour reform was persistent, so that

C.her lobbying for wage and hour reform persistent, that

D.lobbying for wage and hour reform was so persistent,(E)

E.so persistent her lobbying for wage and hour reform, that

这题答案选E。详细解释见“Topway语法大全” Part-2: 228(GWD-5-Q1).

一种更解释里有句话：（1）两个并列分句中，当谓语动词为系动词或者become时，后面一句一定要省略（2）并且and一并省略。


两题有点矛盾。


其次，B选项中的it 如果根据it是完整指代的原则判断，it应该是指代little polar ice，这样后面这句 were it to do so 解释不通。


谢谢！

is 不能省略的。

我觉得这题主要是后面的would提示了我要虚拟，所以一下子就是B了。

这道题考察：1）平行结构：and前后的结构要平行：所以，C D E排除。
2）Agreement：ice cap是单数，所以，只能用is，不能用are A 排除。
3）固定搭配：so...that: A中有两个so不正确。
至于or else 这个，我还没看出

BTW，我不是NN，我只是提出自己想法，你参考下。

当然不能省略，名词在前面verb要跟着:
Xs are so cold and Y is so reflective

C, D选项可以因此排除不用纠结。至如or else用法，我看不出有问题，请NN作答。
