▲高考英语语法必考知识点：祈使句练习题
肯定结构：
（1）Do型(即：动词原形(+宾语)+其它成分)。如：Please have a seat here. 请这边坐。
有的祈使句在意思明确的情况下，动词可省略。如：This way,please. = Go this way,please. 请这边走。
（2）Be型(即：Be +表语(名词或形容词)+其它成分)。如：Be a good boy! 要做一个好孩子!
（3）Let型(即：Let + 宾语 + 动词原形 + 其它成分)。如：Let me help you. 让我来帮你。
否定结构：
（1）Do型和Be型的否定式都是在句首加don't构成：
如：
Don't forget me! 不要忘记我！
Don't make such a noise.不要这么吵。
Don't be late for school! 上学不要迟到！（是系表结构——也就是没有行为动词但是有形容词的那种——就可以使用Don't be，有行为动词的就不能这么用，只能用Don't。）
（2）Let型的否定式有两种：“Don't + let +宾语+动词原形+ 其它成分”和“Let + 宾语 + not + 动词原形 + 其它成分”。
如：Don't let him go. / Let him not go. 别让他走。
（3）有些可用no开头,用来表示禁止性的祈使句。如：No smoking! 禁止吸烟！No fishing! 禁止钓鱼！
A、肯定的祈使句
a.句型：动词原形～.（含有第二人称主语的祈使句，省略主语）
Stand up.起立。
Be quiet，please.请安静。
Be careful！小心！
b.有时，为了加强语气，可以在动词之前加do
Do sit down.务必请坐。
Do study hard.一定要努力学习。
c.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please之前一定要加一个逗号“，”。
Go this way，please.请这边走。
d.祈使句中如果有唤语，一定要用逗号“，”隔开，放在句首或句尾。
Li Ming，come here.李明，过来。
Come here，Li Ming.过来，李明。
e.祈使句和陈述句比较:
陈述句：You sit down.你坐下来。
祈使句：Sit down.坐下（省略主语you）
B、否定的祈使句
句型：Don't /Never+动词原形～
Don't swim in the river.别在河里游泳。
Don't be late.别迟到。
Please don't be noisy.请不要大声喧哗。
Never answer the phone while driving.决不在开车的时候接电话。
注意
表示禁止时，尤其是标语等也可用“No+名词/动名词”来表示。
No smoking!禁止吸烟！
No parking！禁止停车！
No entry！不准入内！
No litter！不准乱扔杂物！
