一、祈使句的概念
祈使句是用于表达命令、请求、劝告、警告、禁止等的句子。祈使句因对象(主语)是第二人称,通常省略主语。祈使句的时态都为一般现在时,句末可以用感叹号来表达比较强烈的语气,也可以用句点结尾。如:
命令:Go and wash your hands!去洗一下你的手!
请求:Be quiet, please. 请安静。
劝告:Be kind to your friends. 善待你的朋友。
警告:Watch your steps. 注意台阶。
禁止:Keep off the grass! 请勿践踏草地!
e.g.Go and wash your hands. 去洗你的手。-命令
Be quiet, please. (Please be quiet.) 请安静。-请求

Go this way, please.=This way, please. 请往这边走。
2. Be+名词短语或形容词+其他成分。如:
Be a good boy!做个好孩子!
Be careful!小心!
3. Let+宾语+动词原形+其他成分。如:
