正确答案:
B:is so reflective that little of the polar ice melts during the summer; were it to do so,
A,is reflective与前面第一个so不平行,后面又出现so that,so..so that不合习惯
B is the best,so..., so..., that,前面两个so平行
C、D,第2个be动词和第一个单复数不一样,不能省略
E,did后面少了so
本题还要注意little of sth. 和little sth.的区别,前者是说sth.中的一小部分,后者little是用来修饰sth.的,是说sth.本身的little。
Were it to do so是虚拟语气。
