标题: 关于旧PREP2-47的问题虚拟语气的问题语法笔记是不是有误麻烦版主给看下

47. (27004-!-item-!-188;#058&003398)

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
句子结构：Those… argue that … data are an… means of… and point out that….
并列的that宾语从句，divide over后跟并列宾语whether… and what…。

考点：动词形式、逻辑表达

1) 动词形式-虚拟语气，表达对将来的假想，用虚拟语气。

2) 逻辑表达，原句中的连词不能随意改变，否则会使原句意思发生变化。

(A)应该用虚拟语气；will it语序不正确，应该是what impact it will have。

(B) warming… will be significant表达的意思与原句不同，使it指代warming，改变原意。

(C)应该用连词and而不是or，因为根据原意remain divided的有两件事：whether significant warming

will occur和what impact，所以要用and。

(D)应该用虚拟语气；连词or改变原意；there be句型不及主谓结构更有效。

(E)正确，虚拟语气would+动词原形have，表对将来的假想，it指代significant warming。

补充说明：
1、divide over

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。

2、虚拟语气的表达

if 条件从句的谓语动词用虚拟语气，主句谓语动词也用虚拟语气

1）表示与现在事实相反：从句用过去时（be 一律用 were），主句用 should（第一人称）/would（第二、三人称）/coul/might +动词原形

If they were here, they would help you.

2）表示与过去的事实相反：从句用 should +动词原形，主句用 should（第一人称）/would（第二

三人称）/coul/might +have +过去分词(过去完成时)

If he had come yesterday, I should / would have told him about it.这个例句明显跟上面解释的不符

含义：He did not come yesterday, so I did not tell him about it.

3）表示与将来的事实相反(对将来的假想)：从句用 should +动词原形，主句用 should（第一人称）

/would（第二、三人称）/coul/might +动词原形

If you succeeded, everything would be all right.这个也不是很相符

到底该怎么用
求NN指点

虚拟语气
1)表示与现在的事实相反:从句的谓语动词用过去时(be一律用were),主句用should(第一人称)/would(第二、三人称)/could/might + 动词原形例:They assumed that if they did not hold it, their grip on Algeria would be always insecure
2)表示与过去的事实相反:从句的谓语动词用had + 过去分词,主句用should(第一人称)/would(第二、三人称)/could/might + have + 过去分词
3)表示与将来的事实相反:从句的谓语动词用should + 动词原形,主句用should(第一人称)/would(第二、三人称)/could/might + 动词原形

同求为啥笔记给的例题
3）表示与将来的事实相反(对将来的假想)：从句用 should +动词原形，主句用 should（第一人称）

/would（第二、三人称）/coul/might +动词原形

If you succeeded, everything would be all right.这个也不是很相符

有问题？

此外这道题目的E选项为什么前面部分没有虚拟 ??????

嗯，这个虚拟语气的总结是有问题的，prep08里也有讲到这块，可以参考下：
prep1-239:
1.虚拟语气：
虚拟条件句的四种形式：

But for N, S + should/would/cold/might + V / (have Vpp.) 若不是N, S应该….

= If it were not / (had not been) for N

= Were it not for N / (Had it not been for N)

= Without N（介词只有without可表虚拟语气）

2.虚拟语气的时态：

时间	从句谓语形式	主句谓语形式
将来	动词过去式(be用were) should + 动词原形 were to + 动词原形	would / should / might / could + 动词原形
现在	动词过去式(be 用 were)	would / should / might / could + 动词原形
过去	had +动词过去分词	would / should / might / could have + 动词过去分词

um...前面部分不需要用虚拟，可以试着翻译一下试试看.
