were it to do so对吗？ 我总觉得少了个not－－－－－were it not to do so?(GWD-3-Q10)

bernadotte

Q18:

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

我倒是犹豫了一下选了C…… 觉得B里面were it to do so里面的it指代有问题…… 不过除去it的问题，表达倒是没有什么问题的，因为were it to do so说明的是Antarctica receives more solar radiation than does any other place on Earth而不是little of the polar ice melts during the summer

bernadotte

我也是选了C 不解

我是看到“the temperatures are so cold and”认为后面也需要是noun be so adj，所以就B了，其他都不对称吧。倒是真没有仔细分辨后面的结构... 汗！

这题的争议焦点在于B和C两个选项，关于这两个选项，主要的争议问题我总结了一下：

对B:
1.是不是少了一个not  
2.it指代的是不是polar ice
对C:
1.or else的用法有多大问题，是不是严重到不能选
2.is是不是可以省略

关于这些问题，总结huangzhuom大仙和aeoluseros斑斑的意见最后结论：

对B：
1.aeoluseros斑斑认为后面的were it to do so并没有少了not，因为前面的 little of the polar ice melts during the summer是一个否定含义的句子，所以后面were it to do so是一个肯定含义的句子，也就是说不少的polar ice。
可以以下句作为类比(excerpt from CFA textbook)：
Terminal value does not dominate the intrinsic value estimate, as is the case with dividend discount and free cash flow valuation models. (as is the case with中的case是指dominate the intrinsic value estimate)
2.it指代的应该是little of polar ice,类比OG12-43的C选项：
43. Laos has a land area about the same as Great Britain but only four million in population, where many are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.
(A) about the same as Great Britain but only four million in population, where many
(B) of about the same size as Great Britain is, but in Laos there is a population of only four million, and many
(C) that is about the same size as Great Britain’s land area, but in Laos with a population of only four million people, many of them
(D) comparable to the size of Great Britain, but only four million in population, and many
(E) comparable to that of Great Britain but a population of only four million people, many of
这一题OG对C的解释包括了划线部分最后一个词them的指代不明，也即说明了语法上/语感上them不能直接指代for million people，而是指代了a population of only four million people。而总所周知对于，it和they这种具象性指代都是指代entire noun (phrase)的，所以it在本帖所讨论题中应该是完全指代了little of polar ice，而不仅仅是Polar ice.

对C：
1.or else显得后面的情况跟前面情况的发生概率相等，所以后面的情况要用虚拟语气引导（引用斑斑）
2.依然悬而未决，暂认为不可省略。

谢谢 这么说是少了个NOT，B是答案了吗

果汁软糖

B是答案 但是not的问题……依然不好说

leen3306

省略了if，were提前，解释为如果温度和ice cap有反应的话，水平面就会上升多少。。，我是这样理解的

gracezz

顶啊！！！！我也选了C。。。。。。

gracezz

觉得were it to do so  不用加not呀，前面说little of polar ice meltes，几乎极地冰都不化，后面说如果这些冰化了的话，就会淹了哪哪哪的。。。所以不用加not.。。
