第六课时 情态动词和虚拟语气

李仕才 [感 悟 高 考]

1.________ not for the support of the teachers, the student could not overcome her difficulty.(2017·江苏卷) A.It were C.It was

B.Were it D.Was it

答案 B [虚拟语气中,be动词统一用were;虚拟语气的省略形式是把if省略,同时把were/should/had提前,即Were/Should/Had I...,故选B。句意:要不是老师们的支持,该生是无法克服困难的。]

2.Samuel, the tallest boy in our class, ________ easily reach the books on the top shelf.(2017·北京卷) A.must C.can

B.should D.need

答案 C [must必须;should应该;can能;need需要。句意:Samuel,我班最高的男生,能很轻松地够着书架顶上的书。]

3.If the new safety system ________ to use, the accident would never have happened. (2017·北京卷) A.had been put C.should be put

B.were put D.would be put

答案 A [句意:如果这个新的安全系统被投入使用的话,这个事故就不会发生了。根据主句would never have happened确定是对过去情况的虚拟,所以从句谓语用had done形式。] 4.My room is a mess, but I ________ clean it before I go out tonight. I can do it in the morning.(2017·天津卷) A.daren’t C.needn’t

B.shouldn’t D.mustn’t

答案 C [句意:我的房间很乱,但是在今晚我出去之前不需要打扫,我可以明天早晨再打

尚水出品

扫。daren’t不敢;shouldn’t不应该;needn’t不需要;mustn’t不许。根据句意,故选C。]

5.—Do you have Betty’s phone number?

—Yes. Otherwise, I ________ able to reach her yesterday.(2017·天津卷) A.hadn’t been C.weren’t

B.wouldn’t have been D.wouldn’t be

答案 B [句意:——你有贝蒂的电话号码吗?——有。否则我昨天就联系不到她了。标志词otherwise相当于一个条件状语从句:If I hadn’t have her phone number,即对过去的虚拟的条件状语从句,可以判断出主句用wouldn’t have done表示对过去情况的虚拟,故选B。]

[要 点 精 析]

=If you hadn’t helped me,I wouldn’t have succeeded anyway. 没有你的帮助,我无论如何也不会成功。 三、if的省略

Your suggestion that the door (should) be shut when we leave is reasonable. 你的那个当我们离开的时候应该关上门的建议是合理的。 五、wish宾语从句中的虚拟语气

1. 对现在情况的虚拟:wish+主语+动词过去式(be用were) I wish (that) I were a bird and could fly freely in the sky. 但愿我是一只小鸟,能在天空自由飞翔。

2. 在“It is (about/high) time+that从句”中,谓语动词常用过去式或“should+动词原形”表示虚拟语气,注意should不可省略。

3.as if,as though引导的表语从句和方式状语从句中常用虚拟语气,与现在事实相反用一般过去时;与过去事实相反用过去完成时。 It seems as though it were spring already. 看起来好像已经是春天了一样。

4.if only引导的感叹句中,用虚拟语气表示愿望。

Look at the trouble we’re in.If only we had taken our teacher’s advice! 看看我们所处的困境,要是我们接受老师的建议就好了!

[解 题 策 略]

1.句型提示法

虚拟语气可以用在状语从句、名词性从句、定语从句中,在不同的从句中,虚拟语气用不同的动词形式来体现,如:if非真实条件句(分三种情形),wish后的宾语从句,It is time that...的定语从句等。所以,掌握了各类从句中虚拟语气的动词形式,就基本上掌握了虚拟语气的用法。

If we ________ the other road,we might have arrived here in time for the meeting. A.take C.took

B.had taken D.have taken

答案 B [句意:如果我们走另一条路的话,我们或许能够及时到达这里参加这次会议了。根据主句的谓语动词might have arrived可以推出,本句是与过去事实相反的虚拟语气,所以if条件句中应该用过去完成时。] 2.特定词汇暗示法

英语中某些短语如:If it were not for/had not been for, but for..., if only..., without等,往往要采用虚拟语气,它们对于解答试题有很大的帮助,掌握了这些要点知识,做起题来也就很容易了。

Thank you for all your hard work last week.I don’t think we ________ it without you.

尚水出品

A.can manage C.could manage

B.could have managed D.can have managed

答案 B [根据without you可知,本句是对过去事情的虚拟推测,故用could have+过去分词。]

B.might have gone D.needn’t have gone

C.can’t have gone

6.—What’s your feeling now?

—I am terribly sorry.If only I ________ here yesterday! A.came C.have come

B.would have come D.had come

B.be made D.would be made

答案 B [desire后的宾语从句及所在句子中的名词性从句,均应使用虚拟语气,虚拟形式为“should+动词原形”,其中should可省略,故选B。]

8.They must have enjoyed themselves there,otherwise they ________ so long. A.can’t have stayed C.can’t stay
