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.

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

 答案是 B

 答案是 B

这道题目的争议在B和C上。

C的问题是前面少了is, B是were it to do so 这个结构比较怪异，也有NN认为是虚拟语气的。

我曾经用google 搜过，原文和C比较接近。

我觉得C的那个is完全可以省略，关键是or else得用法是否正确
