祈使句通常用于表示请求、命令、叮嘱、邀请、劝告等,通常可分为三类:
1. 对象为第二人称的祈使句
A. 句型:“(省略主语You)动词原形+其他.”,其否定形式是在句首加“Don’t”。
例:Listen to me. Don’t be late tomorrow!
B. 有时,为了加强语气,可在动词原形之前加do。
例:Do sit down. Do study hard.
2 .对象为第一人称的祈使句
A. 句型:“Let me \ Let us \ Let’s +动词原形+其他.”,其否定形式为“Let me\ Let us \Let’s+not+动词原形+其他.”
例:Let me have a look. Let’s go home now. Let us not stand in the sun.
B. Let us与Let’s区别:Let's包括听话者,Let us不包括听话者。用于反意疑问句时最明显。
例:Let's go,shall we? Let us help you,will you?
3.对象为第三人称的祈使句
A. 句型:Let +第三人称代词宾格或其他名词词组+动词原形+其他.,其否定形式是在句首加“Don’t”。
例:Let him have a try. Don’t let your mother work too hard.
