[讨论]gwd 3-10

看了以前大家讨论的答案是B,不过个人认为是E. 因为说ice cap is reflective 是不正确的，我觉得因该是ice cap reflect the fact that tempratures are so sold. 请大家指点

补充一下题目

Q10:

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,


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


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


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


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

如果单看so。。。that。。。一定选B，但后面又说were it to do so，请nn给解释一下好吗？谢谢！

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

so that

表示目的，按照意思

但是放入全句

意思不通
