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。
为什么要学习虚拟语气？
虚拟语气是四级考试中重点考察的语法 点。历年四级考试中，仅仅单项填空部
分就一共出现了48道虚拟语气的题 目！！！
II. 虚拟语气的最基本形式
非真实性条件句是虚拟语气最基本的表 现形式。
i. 由“if” 来引导的非真实条件句
组成方式： 非真实的条件从句 + 假设结果（主句）

语法要点
虚拟语气 Subjunctive Mood
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…

2. 祈使语气
用于提出请求、命令、建议或是劝告等。

3. 虚拟语气
用于表示主观愿望或假设的虚拟情况。虚拟
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
