一、祈使句的分类
祈使句表请求、命令、叮嘱、邀请、劝告等.祈使句分为第二人称祈使句及第—、三人称祈使句两大类.
1.第二人称祈使句通常用来向听话者发出命令,提出要求或建议.这种祈使句的主语you通常不表示出来,而是以动词原形开头.如:
Stand up!
Don't worry about!

Parents with children go the front!带孩子的家长到前面去!
Mary clean the windows,and you boys wash the floor!玛丽擦窗户,你们男孩子洗地板!
Come in,everybody!每个人都进来!
有时将主语表示出来是为了加强语气或表示“不高兴”、“厌烦”、“鄙视”等情绪.如:
Don't you be late again!你可别再迟到了!
You get out of here!你给我滚出去!
Mind your own business,you!你少管闲事!
2.第一、三人称祈使句是以第一人称和第三人称代词或者名词等作为祈使的对象,这类祈使句通常以let为引导词表建议.如:

Let him be here by 10 o'clock.

祈使句的否定形式是在整个结构之前加don't或never.如:

don't think our school life is colorful. Because we've got so many classes every
day. I wonder whether we can change our school life someday. You see, from
Monday to Friday, I have to stay at school. The only relaxation is to listen to
the radio or play ball games. At weekends, we need to go to school to have
classes, too. I know it's very important for us to study well now. As the
saying goes, "All work and no play makes Jack a dull boy. "I want to step into
the nature. I hope we will have
more activities such as visiting museums,
taking part in different kinds of contests, attending some lectures and so on.
Is it only a dream?
