英语祈使句的用法如下：
1、祈使句的概念
表示请求、命令、建议、祝愿、邀请或要求的句子叫祈使句。用于祈使句句首的动词总是用原形，不能用其他形式。
2、祈使句表示强调
为了加强祈使句的语气，我们通常是在祈使句的动词原形前加上助动词do，此时通常译为“一定”“务必”等。
3、祈使句的否定式
构成祈使句否定式的方法很简单，那就是在动词原形前加don't——不管祈使句所用的动词为什么性质动词，情况都是一样。
4、祈使句与连用please
为了使祈使句的语气变得委婉，我们可以在祈使句的句首或句末加上please——若加在句首，其后不用逗号；若加在句末，则通常会在please前加一个逗号。
5、祈使句的时间概念
祈使句所表示的时间总是指将来，所以与它连用的句子原则上要用将来时态来与它呼应。
6、祈使句的省略
一般说来，祈使句总是要以动词原形开头，但是，在某些特殊情况下，我们可以只用一个词或短语来表示祈使句的意义。
