导读：虚拟语气主要用来表示假设，而非客观存在的事实，所陈述的是一个条件，不一定是事实，甚至完全与事实相反。虚拟语气通过谓语动词的特殊形式来表示。英语中的语气分为陈述语气、祈使语气、虚拟语气三类。虚拟语气表示说话者做出的假设而非事实，或难以实现的情况，甚至表达彻底相反的概念。此外如需表达主观愿望或某种强烈的感情时，也可用虚拟语气。本文为五年级学生整理了虚拟语气的相关语法解析，分享给学生进行学习和针对性练习。

　　一、虚拟现在(Subjunctive Present):

　　虚拟现在的句子，在任何时候都要用动词的原形(root form)，就算是第三人称(he,she, it)也是如此。如：

　　1.1 现在时态(Simple Present): (右边为虚拟语气)

　　I work ---- I work

　　you work ---- you work

　　he works ---- he work (注意到了吗，是 work，不是 works)

　　she works ---- she work (不是 she works 喔)

　　it works ---- it work　(同样不是 it works 喔)

　　we work ---- we work

　　they work ---- they work

　　1.2　现在进行时态(Present Continuous):(右边为虚拟语气)

　　I am working ---- I be working (注意用的是 be，怪怪的!)

　　you are working ---- you be working

　　he is working ---- he be working

　　she is working ---- she be working

　　it is working ---- it be working

　　we are working ---- we be working

　　they are woring ---- they be working

　　1.3　现在完成时态(Present Perfect):(右边为虚拟语气)

　　I have worked ---- I have worked

　　you have worked ---- you have worked

　　he has worked ----- he have worked (用的还是have喔)

　　she has worked ---- she have worked

　　it has worked ---- it have worked

　　we have worked ---- we have worked

　　they have worked ---- they have worked

　　1.4　现在完成进行时态(Present Perfect Continuous):(右边为虚拟语气)

　　I have been working ---- I have been working

　　you have been working ---- you have been working

　　he has been working ---- he have been working　(是 he have, 不是 he has )

　　she has been working ---- she have been working

　　it has been working --- it have been working

　　we have been working ---- we have been working

　　they have been working ---- they have been working

　　二、虚拟过去(Subjunctive Past)

　　虚拟过去的动词无论在什么情况之下都要用过去复数形式。如：动词 be，在虚拟过去中要用 were。

　　2.1　过去时态(Simple Past):(右边为虚拟语气)

　　I worked ---- I worked

　　you worked ---- you worked

　　he worked ---- he worked

　　she worked ---- she worked

　　it worked ---- it worked

　　we worked ---- we worked

　　they worked ---- they worked

　　2.2　过去进行时态(Past Continuous):(右边为虚拟语气)

　　I was working ---- I were working (注意是 I were)

　　you were working ---- you were working

　　he was working ---- he were working (是 he were 喔)

　　she was working ---- she were working

　　it was working ---- it were working

　　we were working ---- we were working

　　they were working ---- they were working

　　2.3　过去完成时态(Past Perfect):(右边为虚拟语气)

　　I had worked ---- I had worked

　　you had worked ---- you had worked

　　he had worked ---- he had worked

　　she had worked ---- she had worked

　　it had worked ---- it had worked

　　we had worked ---- we had worked

　　(耶，全部都用 had ! )

　　2.4　过去完成进行时态(Past Perfect Continuous):(右边为虚拟语气)

　　I had been working ---- I had been working

　　you had been working ---- you had been working

　　he had been working ---- he had been working

　　三、简单的祝愿和命令：

　　3.1　祝愿

　　1.May you be happy. (注意那个be)祝你幸福。

　　2.May you have a good time.

　　3.May the friendship between us last long,

　　4.Have a good journey! 祝你旅途愉快!

　　3.2　命令

　　注意：

　　1.命令虚拟语气只能用在第二人称(you)，而且通常省略主语(也就是you)。

　　2.句子尾通常加上感叹号：!

　　3.虚拟语气动词用一般现在时态(Simple Present)，如：work, be , go

　　4.否定形式的命令语气，可用助动词 do，加上 not。

　　1.Work !

　　2.Work harder !

　　3.Be more alert ! (虚拟语气动词 Be)

　　4.You go out !

　　5.Do not work so hard. (do not 表示否定的虚拟语气)

　　6.Don't be afraid. (口语中常用don't 代替 do not)

　　四、在现在时态句里，用情态动词的过去时态表示说话人的谦虚、客气、有礼、委婉等：

　　1. Would you be kind enough to show me the way to the post office.(情态动词 would,表示客气有礼)

　　2. It would be better for you not to stay up too late.(表示委婉)

　　五、虚拟语气在宾语从句(Subordinate Clasue)中的用法：

　　5.1 在wish后的虚拟语气宾语从句(可省略它的that)：

　　表示：

　　a.和现在的事实相反;

　　b.和过去的事实相反;

　　c.对将来的主观愿望。

　　5.1.1 现在情况的虚拟，从句用过去式或过去进行式(时间上是同时的)：

　　1. I wish (that可省略,下同)I knew the answer to the question.(wish, 动词过去式 knew)
