prep 93 --- divide on/over

hz032478

这道题没有答案
请教一下 divide on/over 分别是什么意思 怎么用呢？我没有查到 谢谢93. 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

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




讨论的答案有说A,E

longshort

ON 关于， over不对。


倾向选b。在出现的变暖是否将会显著以及这将带来的影响的问题上，科学界还存在分裂。

我在google上面查了

on over 都有 就是好像用法不太一样

但是没有查到专门讲用法的

倒 又多了一个意见

YEWCHOW

我认为应该选E。如下原因：
1）句子原意：remain divided的有两件事--whether significant warming will occur和what impact，所以要用and，排除CD

2）虚拟语气：would+动词原形have，表对将来的假想，排除ACD

3）A中的will it语序不正确，应该是what impact it will have

4）E中的it指代significant warming

divide over的用法是在collins字典上查到的（反而没有查到divide on的用法，但也不一定不对）：

divide over: if people divide over sth or if sth divides them, it causes strong disagreement between them.

例句是：The democrats are divided over whether to admit him into their group。

hz032478

Even at that stage in the war, however, amid widespread protests at college campuses, young people were divided over whether the decision to intervene in Vietnam had been a mistake (49% felt it had, 48% disagreed).

But they were divided on whether to go further by calling for a federal law that would impose a complete ban on human cloning. 但他们在是否进一步要求联邦立法强令彻底禁止克隆人这一问题上存在分歧。

可能是查的资料不太对吧。
不过倒是同意这个选项

YEWCHOW

还是那句话，on或over不是决定选项正确与否的关键，偶没查到，本也不该说on错的（改一下贴子）。

F大侠不是说不考介词么？就不要在这上面较劲了，找其它错误好了。

另外，偶很少上网上搜句子，因为不甚可靠，就像中国人写文章一样会犯语法错误一样（这两个一样是不是语意重复？），况且常常是什么用法都能查得到，更不具有参考价值了。（偶自己的做法，别拍啊！）
