祈使句是表示请求、命令、建议等的句子。句子中通常不出现主语,谓语动词一律用原形。根据句子语气的强弱,句末用感叹号或句号。
一、祈使句的肯定式1. 以行为动词原形开头,简称D型。 e.g. Cme here. 到这儿来。2. 以动词be开头,简称Be型。 e.g. Be quiet, please. 请安静。3. 以Let开头,简称Let型。 e.g. Let’s g! 咱们走吧!
注意:有时可在祈使句的句首或句尾加上please,使语气显得客气、有礼貌。如果在句尾加please,应该用逗号与前句隔开。e.g. G this way, please. 请这边走。
二、祈使句的否定式1. D型和Be型的否定式是在句首加dn’t。 e.g. Dn’t sit here. 不要坐在这儿。 Dn’t be late. 别迟到。2. 以let开头的祈使句,其否定式有两种: 一种是直接在句首加dn’t,另一种是“let + 宾语 + nt +动词原形+ (其他)”。 e.g. Dn’t let him g. 不要让他走。 Let’s nt g there. 咱们别去那儿。
注意:“N+名词/动词⁃ing形式”表示禁止或规劝,常用于公共场所。e.g. N phts! 禁止拍照! N smking! 禁止吸烟!
