祈使句（Imperative Sentence）
 一．      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，因此在学校文法中也常称为命令句。       祈使句因对象（即主语）是第二人称，所以通常都省略。祈使句的动词都为一般现在时，句末则使用句号来表示结束。.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“，”。二、相关口令   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。   三、表现形式   ●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! Be quite.安静  Be careful！小心！    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! 四．反意疑问句， 祈使句后可以加一个简短问句，使语气变得客气一些. 　　如：Have a rest,will you . 　　  Stand up,will (won't) you . 注意： Let''s go，shall we？          Let us go，will you？           祈使句练习一、将以下祈使句改为否定式：
