高中英语知识点归纳虚拟语气的运用
高中英语知识点归纳虚拟语气的运用虚拟语气是英语中一个重要的语法现象，它在日常交流和书面表达中经常被使用。
本文将对高中英语中虚拟语气的运用进行归纳总结。

表达方式为"If + 主语 + 动词的过去式，主语 + would/should + 动词原形"。
这种虚拟语气用来表示与事实相反的假设情况。
例如：If I were rich, I would travel around the world.（如果我有钱，我会周游世界。
）2. 类型2：对现在或将来的不可能实现的愿望。
表达方式为"If + 主语 + 过去式，主语 + would/should + have + 过去分词"。

例如：If I had studied harder, I would have passed the exam.（如果我学得更用心些，我就能通过考试了。
）3. 类型3：对过去的虚拟情况。
表达方式为"If + 过去完成时，主语+ would/should + have + 过去分词"。

高中英语语法-虚拟语气全总结
高中英语语法-虚拟语气全总结虚拟语气通常用于表达与现实相反的假设情况。
在非真实条件句中，虚拟语气的形式有两种：与现在事实相反的假设和与过去或将来事实相反的假设。
与现在事实相反的假设通常使用if+主语+助动词的过去式（如were。
did。
had）+动词原形，主句则使用XXX动词原形。
例如：If I had time。
I would XXX。
如果我有时间，我会参加会议。
与过去或将来事实相反的假设则有三种形式：①if+主语+动词过去式；②if+主语+wereto+动词原形；③if+主语+should+动词原形（注意不能是would）。
主句同样使用XXX动词原形。
例如：If you had taken my advice。
you would not have failed in the exam。
如果你听了我的建议，你就不会在考试中失败了。
在错综时间条件句中，动词形式要根据表示时间的状语从句作出相应的调整。
另外，在条件句中可以省略if，把were、had、should提到句首，变成倒装句式。
例如：Were I at school again。
I would study harder。
如果我还有上学的机会，我会更加努力研究。
Had you arrived earlier。
you would have caught the bus.If it rains tomorrow。
XXX climbing.What would you do with a n dollars?We couldn't have finished the work ahead of time without your help.Otherwise。
I would have taken part in the sports meeting.XXX me of your birthday。
or else I would have known nothing about it.A man who s drinking water would be dead in about seven days.I might have been XXX assistance。

虚拟语气如何用（1）对现在状况的虚拟对现在状况的虚拟，条件句中谓语动词用一般过去时，主句用“would/should/might/could+动词原形”。

高考英语助动词虚拟语气用法大全动词的语气—虚拟语气一、语气的定义和种类l、语气：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 re not redy. 我们没准备好。
Wht ine dy it is!多好的天气啊!(2)祈使语气: 表示说话人的建议、请求、邀请、命令等。
如: Open the door, plese。
请打开门。
(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、假设或推测等。
如: I I were you, I should study English. 如果我是你，我就学英语了。
My you succeed! 祝您成功！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，就是真实条件何。
在这种真实条件句中的谓语用陈述语气。
如: I it doesn’t rin to morrow, we will go to the prk. 如果明天不下雨，我们就去公园。
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: I he hd seen you yesterdy, he would hve sked you bout it. 如果他昨天见到你，他会问你这件事的。
(事实上他昨天没见到你，因此也未能问你这件事。
)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。
现将虚拟条件从句和主句的动词形式列表如下:从句主句与现在事实相反动词的过去式（be的过去式一般用were）w ould/ should/ could/ might + 动词原形与过去事实相反hd + 过去分词would/ should/ could/ might + hve + 过去分词与将来事实相反动词过去式，should + 动词原形，wereto + 动词原形would/ should/ could/ might + 动词原形注: 主句中的should只用于I、we，但在美国英语中，should常被would代替；从句中的should 可用于各种人称。
l、表示与现在事实相反的假设和结果。
如: I my brother were here, everything would be ll 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: I you hd tken my dvice，you wouldn＇t (couldn’t) hve iled in the exm. 如果你按照我的建议去做，你一定不会(不可能)考试不及格。
3、表示与将来事实可能相反的假设和结果。
如: I it were Sundy tomorrow, I sho uld (would，could，might) go to see my grndmother. 如果明天是星期天，我就(可能)去看望我奶奶。
I 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: I you hd listened to the doctor, you would be ll right now. 如果你当初听了医生的话，身体现在就好了。
(从句动作指过去，主句动作指现在)5、虚拟条件句可以转换成下列形式:(l)省略连词i。
在书面语中，如果虚拟条件从句中有were，hd 或should，可以把i省略，把这几个词放到主语之前，构成主谓倒装。
例如: Should he come (I he should come), tell him to ring me up. 他要是来了，让他给我打个电话。
Were I you (I I were you), I would not do it. 我要是你，就不做这事。
(2)用介词短语代替条件状语从句。
有时假设的情况并不用条件从句表示出来，而是通过介词短语来表示。
如: Without ir (I there were not ir), there would be no living thing s. 如果没有空气的话，就不会有生物了。
But or your help (I it hdn’t been or your help) I couldn’t hve done it. 要是没有你的帮助，我就不可能完成这件事。
假设的情况有时可以通过上下文或其他方式表现出来。
如: I ws busy tht dy. Other wise I would hve gone there with them. (I I hdn’t been busy tht dy, I would hve gone t here with them.) 我那天很忙，否则，我就和他们一起去那儿了。
(如果我那天不忙的话，我就……)；I would hve inished the work, but I hve been ill. (I I hdn’t been ill, I would h ve inished the work.) 我本来该完成这项工作的，但我生病了。
(如果我没生病的话，我就会完成……)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 hve wshed your clothes yoursel. 你本可以自已洗衣服的。
省去了"I you hd wnted 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: I my grndmother were with me! 如果我的祖母与我在一起多好啊!(事实是:祖母已不在世。
)；I only she hd not let! 如果她没走就好了!(事实是:她已经走了。
)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 importnt (strnge，nturl，necessry)tht…"这类句型里，tht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: It is importnt tht every member (should) inor m himsel o these rules. 重要的是每个成员知道这些规则。
2、虚拟语气在宾语从句中用法：(1)在动词wish后的宾语从句中，表示与现在或过去的事实相反，或对将来的主观愿望，从句通常省略连词tht。
1)表示对现在情况的虚拟:从句动词用过去式或过去进行式(be动词一般用were)。
如: I wish I knew the nswer to the question. 我希望知道这个问题的答案。
(可惜不知道)；2）表示对过去情况的虚拟:从句动词常用"hd十过去分词"。
如: I wish (wished) I hdn’t spent so much money. 我后悔不该花那么多钱。
(实际上已经花掉)；3)表示对将来的主观愿望:谓语动词形式为"would十动词原形"。
此时要注意，主句的主语与从句的主语不能相同，因为主句的主语所期望的从句动作能否实现，取决于从句主语的态度或意愿(非动物名词除外)。
如: I wish it would stop rining. 但愿雨能停止；I wish you would come so on. 但愿你立刻来。
(2)在suggest，demnd，order，propose，insist，commnd，request，desire等动词后的宾语从句中，谓语动词用“should + 动词原形”，表示建议、要求、命令等。
如: I demnd tht he (should) nswer me immeditely. 我要求他立刻答复我。
3、虚拟语气在状语从句中的用法(1)在带有even i/ even though引导的让步状语从句的主从复合句中，主句和从句都用虚拟语气，动词形式与含有非真实条件句的虚拟语气相同。
如: Even i he hd been ill, he would hve gone t his oice. 即使生了病，他俩去办公室。
(2)由s i或s though引导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“hd十过去分词”。
如: He treted me s i I were strnger. 他那样对待我，好像我是陌生人似的。
She tlked bout the ilm s i she hd relly 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。
(3)在in order tht或so tht引导的目的状语从句中，谓语动词多用“could或might（有时也用should）+ 动词原形”。
如: Mr green spoke slowly so tht his students could (might) her clerly. 格林先生说得很慢，好让学生听清楚。
4、虚拟语气在定语从句中的用法：在"It is time (tht) …"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: It’s (high) time we did our homework. 我们该做作业了。
5、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 would be better or you not to sty up too lte. 你最好别太晚睡觉。
(2)在一些习惯表达中。
如: I would rther not tell you. 我宁愿不告诉你。
(3)用“my + 动词原形”表示"祝愿"、"但愿”，此时my须置于句首（多用于正式文体中）。
