任务六：祈使句的用法

  ●祈使句的定义

用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句最常用于表达命令，因此也常称为命令句，表达说话人对对方的叮嘱、劝告、希望、禁止、请求或命令等。祈使句一般以动词原形开头，无时态和数的变化，句末用句号或感叹号，用降调。

●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!
