if虚拟语气的三种时态 虚拟语气考点有哪些(2)
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)
谈谈虚拟语气(Subjunctive Mood)(四)
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)

c.对将来的主观愿望。
