祈使包含了祈願和命令，God bless you，和省略You沒關係，但為何仍用原形?
感謝Big brother為此找到這麼多的寶貴資料，form and use沒問題，我想知道的是source。
God bless you.正是Big brother所提的祈使句(5)；May + 主詞....?應是疑問句，May God bless you.是祈願的直述形，那May 想必是倒裝而來，從何倒裝？想必是關鍵.
因為God bless you 是來自 May God bless you，May 這個助動詞為bless的原形找到文法的依據，May God bless you這個慣用語的來源才是它文法上的依據，我想要的是這個。

我特地查了這本書對 Imperatives 的解釋
Swan, Practical English Usage, Third Edition, Oxford University Press, 2005
1 forms and use
In sentences like Come here, Be quiet, Have a drink or Don't worry about it, the verb forms come, be, have and don't worry are called 'imperatives'.
Affirmative imperatives have the same form as the infinitive without to; (元型動詞,沒有疑問) negative imperatives are constructed with do not (don't).
Imperatives are used, for example, to tell or ask people to do things, to make suggestions, to give advice or instructions, to encourage and offer, and to express wishes for people's welfare.
Look in the mirror before you drive off.
Please do not lean out of the window.
Tell him you're not free this evening.
Try again - you nearly did it.
Have some more tea.
Enjoy your holiday.
An imperative followed by and or or can mean the same as an if-clause.
Walk down our street any day and you'll see kids playing.
(= if you walk...)
Shut up or I'll lose my temper. (= if you don't shut up...)
Don't do that again or you'll be in trouble.
2 emphatic imperative: do sit down
We can make an emphatic imperative with do.
Do sit down.
Do be more careful.
Do forgive me.
3 passive imperative: get vaccinated
To tell people to arrange for things to be done to them, we often use get + past participle.
Get vaccinated as soon as you can.
4 do(n't) be
Although do is not normally used as an auxiliary with be, this happens in negative imperatives.
Don't be silly!
Do be can begin emphatic imperatives.
Do be quiet!
5 subject with imperative
The imperative does not usually have a subject, but we can use a noun or pronoun to make it clear who are speaking to.
Mary come here -- everybody else stay where you are.
Somebody answer the phone.
You before an imperative can suggest emphatic persuasion or anger.
You just sit down and relax for a bit.
You take your hands off me!

Note the word order in negative imperatives with pronoun subjects.
Don't you believe it. (NOT You don't believe it.)
Don't anybody say a word. (NOT Anybody don't say...)
6 question tags
After imperatives, common question tags are will you? would you? can you? and could you?
2011-08-01 13:25:08 補充：
Wait here for a minute, would you?
Get me something to drink, can you?
Can't you and won't you are more emphatic.
Be quiet, can't you?
Sit down, won't you?
After negative imperatives, will you? s used.
Don't tell anybody, will you?

7 word order with always and never
Always and never come before imperatives.
Always remember what I told you. (NOT Remember always...)
Never speak to me like that again.

[drive] slow down!
You, [be] bastard!

主詞一定是第二人稱 YOU 也就是說這句話一定是和在與說話者對話的人那個人說的, 以中文來舉例:
A對B 說: 請坐! ....A 絕對不會說:你請坐.
另外如: 開門! 開燈! 等句子時,同常不會加個"你"
如: Sit down. Turn off the light. Open the door.

和主詞 you 省略當然有關係!
you 的後面是用原形動詞,所以沒有了you 還是用原形動詞
(you) open the door.
(you) stand up, please.
You are a good boy.
(you) Be a good boy. ..................原形動詞 be

God bless you. 不是命令句
原句: May God bless you. ....
將 may 省略.

版主,我看不出來 樓下的(5) 和 May God bless you. 有何關係!
May 助動詞, 意為 "可以" 用於疑問句 :
May I go now? 我可以走了嗎? 此屬問句.....後面有問號喔 !
may 助動詞,意為 "猜測, 也許" 用於疑問句 :
May he be a student? 他會是個學生嗎?
而 May God bless you. 是一個習慣用語,may 要當"願"來說,不是疑問詞.
