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

答案选B，我选的C 请问B中的it指代的是什么呢？to do so又指的什么呢？

IT指的是ICE。
WERE IT TO DO SO是条件
= IF IT WERE (必须是WERE，不是神马别的) TO DO SO

这里是IF省略，WERE 动词提前

冰不会化，要是化了，海平面...

B和前面 temperatures are so cold 平行，C少谓语IS

C中如果补上谓语，后面的 or else搭would有问题么？

※固定搭配so.. that。yet the temperatures are so cold and需要有同样的内容并列，即be+ so adj.

※句子逻辑关系：至少不能用or连接，也不能形成转折关系otherwise作连词时，意为否则，不然
※were it to do so是个倒装，但是根据前两项就可以排除得出正确选项了
