这个句子陆锦林曾经谈过,他将祈使句解释为三类:无主语祈使句,有主语祈使句,Let祈使句。例如:
1. Be seated.(无主语祈使句)
2. You call the doctor up!/Everybody shut his eyes.(有主语祈使句)
3. Let me have a try.(Let祈使句)
此外,陆锦林也有这样的说法:一些表示请求的问句也可看作是有主语祈使句。这一说法似乎章振邦也有所谈及。例如:
Will you please pass me the sauce?
当然,也会有相应的否定祈使句形式。例如:
1. Don't be nervous.
2. Don't you mind./Don't you say that again!
3. Don't anyone open the door.(如网友例句)
4. Don't let's start that./Let's not argue any more./Let's don't be greedy.
根据王国栋的说法,否定祈使句也有采用“动词原形+not/no”形式的。例如:
1. Judge not according to the appearance. (The Bible,John《圣经.约翰福音》)
2. My fellow Americans: ask not what your country can do for you,ask what you can do for your country.(John Kennedy,Inaugural Address 1961约翰.肯尼迪《就职演说》)
3. Go no farther!
当然,其他学者对祈使句还有不同的分类方式,何桂金解释为,一般祈使句,Let祈使句,无动词祈使句三类。他所说的一般祈使句类似陆锦林所说的无主语祈使句和有主语祈使句。补充一些无动词祈使句:
1. Silence!
2. All aboard!/Hats off!
3. Louder,please.
4. After you. (您先请。)
