祈使句
用来表达命令、请求、劝告、警告、禁止等的句子叫作祈使句。
祈使句最常用于表达命令，因此也常称为命令句。
句子中通常不用主语，谓语动词一律用原形。句末用感叹号或者
句号，用降调。
Let's fly a kite
详解
此句为let引导的祈使句，表示建议。let's是let us的缩写。
Let's go home.
我们回家吧。
Let's clean the floor.
我们扫地吧。
拓展
don't引导的否定祈使句语气比较强烈，let's引导的否定祈使句
语气比较委婉。
Don't disturb him.
不要打扰他。（直接命令，语气强烈）
Let's not disturb him.
咱们不要打扰他。（语气委婉）
let's也可以写出let us，但是所表示的意义有所不同，用
“let's”时，包括听话者在内；用“let us”时，则不包括听者。
Let's try it,shall we?
咱们再试试，好吗？（包括听者）
Let us do it by ourselves will you?
让我们自己做，好吗？（不包括听者）
否定的祈使句句型
1）Don't+动词原形。
Don't swim in the river.
别在河里游泳。
Don't be late.
别迟到。
Don't run.
不要跑。
2）表示禁止时，尤其是标语等也可用“No+名词/动词-ing”来表示。
No smoking！禁止吸烟！
No parking！禁止停车！
No spitting！禁止吐痰！
含有第二人称主语的祈使句：
You go and close the window.
你过去把窗户关上。
You go and tell him not to do that.
你去告诉他别那样做。
You go and tell him,Chirs.
克里斯，你去告诉他。
祈使句把主语“you”，表达出来。
能使对方听起来觉得柔和些。
有时为了加强语气，可以在动词之前加do。
Do sit down.
请务必坐下。
Do bring your cell phone.
一定要带手机。
用客气的语气表示祈使句时，可在句首或句尾加上please，
但如果在句尾加please，那在其前一定要加“，”。
Go this way,please.
请这边走。
Danny，please don't run！
丹尼，请不要跑！
祈使句的用法
祈使句主语常省去，只要谓语就可以。
表示请求或命令，加上please表客气。
如果变成否定句，加上don't是规律。
