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(Modal Verb)的过去时态(could,might,should,would)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：

　　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)：
