高中英语语法课件_虚拟语气(全)(共55张PPT)详解

解题思路
本题前半句是表示与过去事实相反的虚拟条件 从句,后半句是表示与过去事实相反的主句。 相当于:If he had worked harder, he would have got through the exams.本题的 答案是B. would have got through。 选项A. must have got through(肯定通过) 表示一种对过去事情的主观推测,不是与过去 事情相反的情况。另外,must不能用在虚拟条 件句中。 选项C. 和D. would / could get through (就会通过)是虚拟语气现在时的一种表示方 法,表示与现在事实相反。

I.什么是语气?
语气是动词的一种形式,用以表示说话 人对某种言行或某种事情的看法或态度。 英语有三种语气:陈述语气,祈使语气 和虚拟语气。 陈述语气一般用来讲述事实或提出疑问。 常常用于陈述句、疑问句和感叹句。 e.g. I took a shower after supper. What are you going to do? What a beautiful flower!
A case in Point
P. 37 (l. 28) in College English II. Unit 3 Were it left to me to decide whether we should have a government without newspapers or newspapers without a government, I should not hesitate a moment to prefer the latter. = If it were left to me to decide…

语气中说话者所讲的内容往往是与事实相反 的;或是其实现的可能性微乎其微, 甚至没 有实现的可能性, 但是有时为了使说话的语 气客气、缓和、委婉, 也使用虚拟语气。
If you came to Brunei, you would have to take off your shoes before going into someone’s house.
If you had been in Korea with me last year, you would have attended a wedding ceremony.

1.2.虚拟语气用于宾语从句 1.2.1.句型“…wish that…” 在wish后的that宾语从句中:1.如果表示对现在的愿望,从句谓语要使用过去时: (1)从句谓语动词如果是be,则用were形式。 (2)从句谓语动词如果是行为动词,则用过去时形式。--I wish I were a bird. 但愿我是只鸟儿。--I wish you didn’t talk like that. 但愿你没有那样说。
1.1.6.含蓄条件句
英语中有些句子从形式上看不包含条件从句,但在意义上却是非真实条件句,这类句子称为含蓄条件句,这样的句子可分为三类
1.省略整个条件句 --Such mistakes could have been avoided. (省略了if we had been more careful). 这样的错误本来是能够避免的。 --I should have caught the train. (省略了if I had left a little earlier) 我本应该赶上火车的。
2.如果表示对将来的愿望,从句谓语动词用 “would (could, might )+动词原形” 的形式。 --I wish you would do the favor for me. 但愿你会帮我这个忙。 --I wish I could speak several languages. 但愿我会说好几种语言。
1.1.2.和过去事实相反的非真实条件句
这类非真实条件句表示过去未发生的事情,和过去事实相反。比如:
--If I had left a little earlier ,I would have caught the train. 如果我早一点离开的话,我就会赶上火车了。--The man’s life might have been saved if he had been sent to a better hospital.如果把那个人送到一家更好的医院的话,他也许回被救活的

实战练习 5
2001年1月大学英语四级题目: Some women a good salary in a job instead of staying home, but they decided not to work for the sake of the family. A. must make B. should have made C. would make D. could have made
解题思路
这是一道错综时间虚拟条件句。 在本句中,从句是对过去发生的事情进 行假设,主句是对现在情况的假设。 译文:当你掉下来时,如果不是我在梯 子下面把你接住,恐怕你现在就不会笑 了。选A
实战练习 2
If you had taken your medicine yesterday, you ___ well now. A. are B. had been C. would be D. were 正确答案: C
祈使语气主要用于祈使句。 e.g. Get out of here! 虚拟语气
II. 什么是虚拟语气?
虚拟语气是一种特殊的动词形式,表示说话人 所说的话不是事实,而是想象、假设、建议、 打算、意见、愿望、怀疑、推测、喜悦等等。 e.g. If we had met her last night, we would have told her what had happened. 如果我们昨晚见到她,我们就会告诉她发生了 什么事。 (实际上,我们并没有见到她,也没有告诉她 所发生的事。)
注意!!!
如果条件从句是否定式,倒装时只能把 not 放在主语之后,不能用缩写式把not 放在主语之前。 e.g. Had you not told me about the matter, I should never have known the whole thing. (不能说:Hadn’t you told me…)
