1 祈使句（Imperative Sentence）1.1 定义 用于表达意愿、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，句末则使用句号或感叹号来表示结束，读时用降调例： Go and wash your hands. （去洗你的手——命令） Be quiet, please.（Please be quiet.） （请安静——请求） Be kind to our sister. （对姊妹要和善——劝告） Watch your steps. （走路小心——警告） Look out！Danger！ （小心！危险！——强烈警告） Keep off the grass. （勿践草坪——禁止） No parking. （禁止停车——禁止） No eating or drinking. (禁止吃喝。
——禁止) No littering. (禁止乱扔垃圾——禁止) 祈使句也常把主语“You”表达出来，使对方听起来觉得柔和些，例如： You go and tell him, Chris. （克立斯去告诉他 1.2 概念口诀 祈使句无主语，主语you常省去； 动词原形谓语当，句首加don't变否定； 朗读应当用降调，句末常标感叹号 1.3 表现形式1.3.1 肯定句 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 1.3.2 否定句 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！ 是系表结构——也就是没有行为动词但是有形容词的那种——使用Don't be 有行为动词的就不能这么用，只能用Don't 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”。
