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

答案是B，我选的C。网上查了一下发现这道题争议挺大，去一个国外的论坛上找到了外国人对这道题的解释：

is reflective, so that little polar ice melts during the summer; otherwise, ( nonparallel - so cold...so reflexive...that)
B. is so reflective tha t little of the polar ice melts during the summer; were it to do so,( changing the meaning + awkward)
C. so reflective that little polar ice melts during the summer, or else (correct - here "is" is ellipsed)
D. reflective, so that little of the polar ice melts during the summer, or (the same as in A)
E. reflects so that little of the polar ice melts during the summer; if it did ( nonparallel + ambiguous antecedence )

觉得挺有道理。可究竟选B还是C呢？

我心向明月

嗯，我也觉得C比较对呢？
