英语祈使句
一、祈使句
祈使句是表示命令、请求的句子。祈使句因为对象（即主语）是第二人称you，所以通常省略。祈使句的动词都为一般现在时，句末则使用问号来表示结束。
1，肯定结构的祈使句常以谓语动词原形开头。
列如：Stand up ,please 请起立
Be careful 小心 Come here Close the door
Open the window Wash your hands
2，否定结构的祈使句常在谓语动词原形前加上Don’t。
Don't forget me 不要忘记我
Don't be late for school 上学不要迟到
Don't open the door
3，let引导的祈使句结构，有以下几种情况：
1.“Let me+动词原形”（let +宾语+动词+其他），意为“请让我……”。Let me help you .让我帮你吧。
2.“Let’s +动词原形”，意为“让我们……”，表示建议或请求。Let's go to school. let's play a game
4,No 开头的祈使句，用来表示禁止。
No smoking禁止吸烟 No fishing禁止钓鱼
二、感叹句
感叹句是用来表示喜怒哀乐等强烈感情的句子，通常由how或what来引导。
