GWD3-Q10

GWD3-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.

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C。我选的是A，感觉SO THAT 也可以直接表结果吧。

另外，尤其困惑的是，B中 were it to do so 是什么鬼东东？

望nn指教

你的答案錯了 正確答案應該是B才對.

A 錯在不平行，so that..的使用方式也不對

DE錯在不平行, so adj, and so adj that…..淘汰DE

C 錯在缺be動詞is.

.<假設語氣>中的<副詞子句>可以省略if,此<子句>中的<助動詞>had,were,should等要移至{主詞}之前。

were it to do so
        假設語氣使用過去式，表示與現在事實相反。

If he were to see you, he would be very surprised.
= Were he to see you, he would be very surprised

请问c项除了缺“is”外还有其他错嘛？or else有什么特殊用法吗？比如or else的前后是否要并列

完全不明白为什么是B，

第一，B选项中的little of违反了原句的意思；

第二，it在虚拟语气的从句中指代不明确

且:

C中的省略be绝对可行,or else也是conj

为什么OA是B????

B选项中it没有什么指代明不明的情况，were it to do so是一种固定的搭配。

自认为并列句的第二个系动词不可以省，从没见过这种用法，可以举例吗？
