标题: GWD3-10 C为什么不可以？be动词要不要省略？

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.

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

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

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

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

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

C为什么不可以？

BY语法上讲两个句子或者三个句子并列，第一句中有be动词或者become，第二句或者第三句话中的be动词或者become必须省略。

答案是B

B中be动词不是没有省略吗？

C岂不是更好？

在5个答案里,前半句合符逻辑和语法的就只有B:

1.只有重复的be动词能省略,is和are是不同的,所以is不能省略;

2.句子的结构是A are so xx and B is so xx that...; so that 结构;

谢谢你的答案，我明白了。

另外，请问C中or else有没有问题？or else这种结构应该怎么样用？

Longman:

2 or else spoken
a) used to say that there will be a bad result if someone does not do something:
Hurry up or else we'll miss the train.
b) used to say what another possibility might be:
The salesman will reduce the price or else include free insurance.
c) used to threaten someone:
Hand over the money, or else!

可能因為"or else"是用在交談, 所以GMAC不接受? 不決定...

msuzengli說的第一點, 我看過我朋友的莫老師's note上有提到, 可是後來看到別一本文法書(Handbook of Good English電騾上有), 說可以省只要功能一致...
看來要看prep/OG上有沒有明確的information
