祈使句是表示请求、命令、建议等的句子。句子中通常不出现主语，谓语动词一律用原形。根据句子语气的强弱，句末用感叹号或句号。
祈使句
一、祈使句的肯定式
1. 以行为动词原形开头，简称Do型。 e.g. Come here. 到这儿来。
2. 以动词be开头，简称Be型。 e.g. Be quiet, please. 请安静。
3. 以Let开头，简称Let型。e.g. Let’s go! 咱们走吧!
注意
有时可在祈使句的句首或句尾加上please，使语气显得客气、有礼貌。如果在句尾加please，应该用逗号与前句隔开。
e.g. Go this way, please. 请这边走。
二、祈使句的否定式
1. Do型和Be型的否定式是在句首加don’t。
e.g. Don’t sit here. 不要坐在这儿。
Don’t be late. 别迟到。
2. 以let开头的祈使句，其否定式有两种：一种是直接在句首加don’t,另一种是“let + 宾语 + not +动词原形+ (其他)”。
e.g. Don’t let him go. 不要让他走。
Let’s not go there. 咱们别去那儿。
注意 “No+名词/动词 ing形式”表示禁止或规劝，常用于公共场所。
e.g. No photos! 禁止拍照！
No smoking！ 禁止吸烟！
