语法讲解：
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。
祈使句无主语, 主语you常省去;
动词原形谓语当, 句首加don't否定变;
朗读应当用降调, 句末常标感叹号。
●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 be late for school! 上学不要迟到!
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!
