1、虚拟语气一、语气（Mood）的定义和种类l、语气：是动词的一种形式，它表示说话人对某一行为或事情的看法和态度。2、语气的种类：（1）陈述语气: 表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。如：We dont have dinner in that restaurant. What an adorable baby it is!（2）祈使语气: 表示说话人的建议、请求、邀请、命令等。如: Open the window, please. Take care of your suitcase.（3）虚拟语气: 表示动作或状态不是客观存在的事实，而是说话人的主观愿望、

2、假设或推测等。如：If I were you, I should study English well. May you succeed!二、虚拟语气在条件从句中的用法条件句有两类，一类是真实条件句，一类是虚拟条件句。如果假设的情况是有可能发生的，就是真实条件句。在这种真实条件句中的谓语用陈述语气。如: If it doesnt rain tomorrow, we will climb the mountain. 如果明天不下雨，我们就去爬山。如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如: If he had seen you yesterday, he wo

3、uld have told you about that. 如果他昨天见到你，他会告诉你那件事的。在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟语气。列表如下：从句主句例句与现在事实相反的假设If + 主语+助动词的过去式（were, did, had）主语+ should/would/could/might+动词原形If I had time, I would attend the meeting.If I were you, I should seize the opportunity to go abroad.与过去事实相反的假设If +主语+had+过去分词主语+should/

4、would/could/might +have+过去分词If you had taken my advice, you would not have failed in the exam.与将来事实相反的假设 If+主语+动词过去式 If+主语+were to+动词原形 If+主语+should+动词原形(注意不能是would)主语+ should/would/could/might+动词原形If you came tomorrow, we would have the meeting.If it were to rain tomorrow, we would put off the spor

5、ts meeting.If he should not come tomorrow, we should put off the meeting till next Monday.1、表示与现在事实相反的假设和结果。如：If my brother were here, everything would be all right. 要是我哥哥在这儿 ，一切都没问题了。2、表示与过去事实相反的假设和结果。如：If you had taken my advice，you wouldnt (couldnt) have failed in the exam. 如果你按照我的建议去做，你一定不会(不可能)

6、考试不及格。3、表示与将来事实可能相反的假设和结果。如：If it were Sunday tomorrow, I should (would,could,might) go to see my grandmother. 如果明天是星期天，我就(可能)去看望我奶奶。If it were to snow this evening, they would not go out. 如果今晚下雪，他们将不出去了。4、有时条件从句中的动作和主句中的动作发生的时间不一致（表示错综时间的虚拟语气），这时动词的形式要根据它所表示的时间加以调整。例如：If you had listened to the doc

7、tor, you would be all right now. 如果你当初听了医生的话，身体现在就好了。Ifyouhadgonetobedearlylastnight,youwouldnotbesosleepynow.5、虚拟条件句可以转换成下列形式（1）省略连词if,构成主谓倒装。在书面语中，如果虚拟条件从句中有were，had或should，可以把if省略，把这几个词放到主语之前，构成主谓倒装。例如: Should he come (If he should come), tell him to call me back. Were I you (If I were you), I wo

8、uld not miss the plane. （2）用介词短语代替条件状语从句。如：Without air (If there were not air), there would be no living things. 如果没有空气的话，就不会有生物了。But for your help (If it hadnt been for your help), I couldnt have done it. 要是没有你的帮助，我就不可能完成这件事。 I was busy that day. Otherwise I would have gone there with them. 我那天很忙，否

9、则，我就和他们一起去那儿了。I would have finished the work, but I have been ill. 我本来该完成这项工作的，但我生病了。6、省去条件从句或主句：表示虚拟语气的主句或从句有时可以省略，但其含义仍可以推知。（1）省去条件从句。如: You could have washed your clothes yourself. 你本可以自已洗衣服的。省去了If you had wanted to, (事实是:你自己没洗衣服，因为你不想洗)（2）省去主句(常用以表示愿望)。如: If my grandmother were with me! 如果我的祖母与我

10、在一起多好啊!If only she had not left! 如果她没走就好了!三、虚拟语气的其他用法l、虚拟语气在主语从句中的用法：在It is important (strange，natural，necessary)that这类句型里，that所引导的主语从句中的谓语动词常用 “should十动词原形”结构，表示某事是重要、奇怪、自然、必要等意义。如： Itissuggestedthatpupils(should)wearschooluniforms.It is important that every member (should) obey these rules. 重要的是每个

11、成员都应该遵守这些规则。2、虚拟语气在宾语从句中用法：（1）wish后的宾语从句：表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；表示与过去相反的愿望，从句谓语用过去完成时:had十过去分词；表示将来没有把握或不太可能实现的主观愿望，常用“would (could)+动词原形”。I wish I knew the answer to the question.

14、的状语从句表示比较或方式时。从句谓语形式为动词的过去式(be用were)或 “had十过去分词”。如：He treated me as if I were a stranger. 他那样对待我，好像我是陌生人似的。She talked about the film as if she had really seen it. 她谈论那部影片，就好像她确实看过一样。注：如果表示的事情可能会发生，那么方式状语从句中的谓语动词可用陈述语气。4、 表语从句中的应用上述动词相应的名词形式作主语+连系动词构成表语从句，要用虚拟语气，即“should+动词原形”.常用名词形式有：advice,decision

15、,demand,proposal,request,order,suggestionHis suggestion was that the meeting (should) be delayed.5、 虚拟语气在定语从句中的用法：在It is time (that) 句型中，定语从句的谓语动词常用虚拟语气表示将来，动词形式一般用过去式，意思是该干某事的时候了。如：Its (high) time we did our homework. 我们该做作业了。6、虚拟语气在简单句中的用法（1）情态动词的过去式用于现在时态时，表示说话人的谦虚、客气、有礼貌，或委婉的语气，常见于日常会话中。如：It wou
