Be quick/fast!Lets play basketball.Lets go out f

32、or fun.(2) 否定祈使句的构成： Do型和Be型的否定式，在动词前加dont或never，即“Dont do/be sth.”或者“Never do/be sth.”。 Let型的有两种否定形式：在let前加dont，即“Dont let sb. do sth.”或在let sb.后加not，即“Let sb. not do sth.”。其他类型：“No +v.-ing形式/名词”，用于警示人们不要做某事。例如：Dont come in.Dont be sad.

Its raining hard. 不要出去了。天正下着大雨。Yes, I will. Lily is waiting

34、for me. 不，我要去。莉莉在等我呢No, I wont. I will stay at home. 好的，我不会去的。我待在家就好。4. 其他用法: 祈使句和陈述句的连用(1)祈使句+ and/ then + 陈述句，二者之间表示一种顺承关系。例如：Study hard, and you can get good grades.Be careful, and you will find it easy.Act it now, and our world will be better.Plant more tree, and the earth will be more beautiful

35、.(2)祈使句+ or +陈述句，二者之间表示一种否定条件。例如：Move quickly, or you will miss the bus.Study hard, or you will fail the exam again.Remember these sentences, or you wont pass the test.Be polite to others, or they will be sad because of your words.三、语篇知识清单本单元我们主要学习了如何使用祈使句来表示请求、命令、劝告、警告、禁止。事实上，祈使句在我们的实际生活中使用得非常普遍，在写
