祈使句
考点 1
原文:Sam, sweep the floor, please. 山姆,请打扫地板。
Please clean your desk and chair, Max. 请清洁你的桌子和椅子,麦克斯。
解析:表示请求、命令或劝告的句子叫祈使句。它通常省略主语(you),根据语气的强弱,句末使用感叹号(!)或句号(.),朗读时常用降调。
例如: Go and wash your hands. 去洗你的手。(表示命令)
Be quiet, please. = Please be quiet. 请安静。(表示请求)
Be kind to animals. 对动物友善。(表示劝告)
Keep off the grass. 勿践踏草坪。(表示禁止)
(1) 为了使语气委婉,使用祈使句时可加上please, please可位于祈使句的句首(其后通常不用逗号)或句末(其前通常用逗号)。★★★
❊ 易错点提醒:有的祈使句在意思明确的情况下,还可以省略动词。如:
This way, please. = Go this way, please.
(2) 祈使句的回答可用:“All right./OK./Yes.等” ★★★
Yes, Mum.
Close the door, please.
(3) 祈使句的否定句:一般在动词原形前面加Don’t ★★★
如:Don’t listen to the parrot, Sam! 不要听鹦鹉的,萨姆!
(4) 常见的祈使句类型:
Be型祈使句:Be +(表语) (+其他). 如:Be careful. 小心。
Do型祈使句:实义动词原形 +其他. 如:Come in, please. 请进。
Let型祈使句:Let +宾语+动词原形(+其他). 如:Let me have a look.让我看一看。
