标题: prep 2-47

Those skeptical of the extent of global warming argue that short-term temperature data are an inadequate means of predicting long-term trends and point out that the scientific community remains divided on whether significant warming will occur and what impact will it have if it does.

(A) on whether significant warming will occur and what impact will it have if it does

(B) on whether warming that occurs will be significant and the impact it would have

(D) over whether there will be significant warming or the impact it will have

(E) over whether significant warming will occur and what impact it would have

Those skeptical of the extent of global warming argue that short-term temperature data are an inadequate means of predicting long-term trends and point out that the scientific community remains divided over whether significant warming will occur and what impact it would have.

这里为什么前面用will 后面用would 是虚拟语气吗?

还有 it 指代什么?

是的，是虚拟语气]

意思是如果significant warming ocurring，那么会有什么影响；

plus it指代significant warming

这道题ron大神在曼哈顿里面也说他觉得A对，因为E里面用了would和之前的will occur结构不合，感觉有点争议啊

下面是Ron的解答
hmm... i like (a) best, but only if it was supposed to say 'it will', and you mis-typed it as 'will it'. if the version you've typed is indeed faithful to the original, then, well, all the choices suck.

reasons:
- 'whether...' and 'what impact...' are parallel.
- the meaning is correct.
- the tenses are parallel: 'will occur' || 'will have'.

choice b:
- the original sentence clearly indicates that scientists don't know whether warming will occur in the first place. this wording, though, assumes that warming will occur; according to this sentence, the only thing in doubt is the extent of such warming.
- 'whether...' is not parallel to 'impact'.

choice c:
- 'as to' is dicey.
- 'or' should be 'and' (because they're wondering about both questions).
- past tense 'did' is inappropriate.

choice d:
- 'or' should be 'and'.
- 'whether...' isn't parallel to 'the impact'.

choice e:
- tense inconsistency: 'will occur' isn't parallel to 'would have'. moreover, 'would have' isn't appropriate for the consequences of something that hasn't even happened yet.

what's the oa?
