四、祈使句(exclamatory Sentence)表示请求、命令、禁止、劝告或建议的句子叫祈使句。祈使句的主语往往省略。其常见的句式结构可归纳为四种基本形式：（1）肯定祈使句；（2）否定祈使句；（3）以Let’s开头的祈使句；（4）以助动词do开头的祈使句。

1．肯定祈使句。如：

Stop talking! Come here in time!

2．否定祈使句，即以Don’t或Never开头的句子。如： Don’t talk in class. Never leave today’s work for tomorrow.

3．以Let’s 或let开头的句子。如：

4．以助动词do开头的祈使句，在句中起加强语气的作用，译成“一定，务必”。如：

Do come to see me if you have time.
