祈使句是表示要求、命令或者表达意愿、建议的句子。说话的对象(即句子 的主语)通常是第二人称,习惯上省略。谓语动词用原形,句末用感叹号或句号, 读时用降调。
肯定形式: (谓语)动词原形+其它成分 Stand up, please! 请起立! Be quiet, children! 孩子们,请安静! Let me have a lk. 让我看一看。
否定形式: ▲祈使句的否定式多以d nt(通常缩写为dn’t)开头, 也可由never 引起。 Dn’t be late next time! 下次别迟到! Dn’t take it with yu! 不要把它带走。 Dn’t let her g there. 不要让她去那里。 Never d it like that. 再也不要那样做了。 ▲由let 引导的祈使句的否定形式也可以写为: Let+宾语+nt+动词原形 +其它。 如: Let him nt g there. 不要让他去那里。
口 诀 下面的口诀总结了祈使句的一般规律。一起来看看吧! 祈使句,有特点, 动词原形摆在前, 否定句式也不难, Dn't 放在最前面, 其它一律都不变。
祈使句的应答语 祈使句表示要求、建议对方"将来"做或不做某事, 因此其肯定应答语通常 用I / we will。否定答语通常用 I / we wn't。如: --- Knck n the dr befre yu g in! 进去之前要敲门! --- I will. 是的, 我会的。 --- Dn’t frget t turn ff the lights when yu leave. 离开时别忘记关灯。 --- I wn’t. 不会忘记的。
