(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 (C) as to whether significant warming will occur or the impact it would have if it did (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
这题答案是E 我想问A为什么不对 还有E最后那个 would have是怎么回事 谢谢了！作者: 2017 时间: 2011-4-4 10:01
我认为：E选项后面是假设，假设发生了会怎么样，所以用would have （what impact)作者: lllmmm 时间: 2011-4-4 10:24
那A为什么不对呢 请问作者: 2017 时间: 2011-4-4 11:22
A应该假设，应该也用would作者: mlvince 时间: 2011-4-4 11:22
我觉得a的if it does和whether significant warming will occur 是重复的吧？
