祈使句
表示请求、命令、禁止、劝告或建议的句子，特点是省略了主语。

●肯定结构:
1. Do型(即:动词原形(+宾语)+其它成分)。如:Plea a at 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, plea. = this way, plea. 请这边走。
2. Be型(即:Be + 表语(名词或形容词)+其它成分) 如: 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: 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: me! 不要忘记我!

2. Let型的否定式有两种:
“Don't + let + 宾语 + 动词原形 + 其它成分”
“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。
