　　祈使句

　　用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句通常省略主语，谓语动词用原形，句尾用感叹号或句号。

　　1、肯定结构：

　　1)动词原形(+宾语)+其它成分。如：Please have a seat here. 请这边坐。有的祈使句在意思明确的情况下，动词可省略。如：This way, please. = Go this way, please. 请这边走。

　　2)Be + 表语(名词或形容词)+其它成分。如：Be a good boy! 要做一个好孩子!

　　3)Let + 宾语 + 动词原形 + 其它成分。如：Let me help you. 让我来帮你。

　　2、否定结构：

　　1)don't+动词原形+其他。如：Don't forget me!不要忘记我!Don't be late for school!上学不要迟到!

　　2)Let + 宾语 + not + 动词原形 + 其它成分。如：Let him not go. 别让他走。

　　3)有些可用no开头，用来表示禁止性的祈使句。如：No smoking!禁止吸烟!

　　常见考法

　　对于感叹句和祈使句的考查，常会出现在单选和完成句子中，主要考察两种句子的用法和构成。

　　典型例题：You should not talk in class.(改写同义句)

　　in class.

　　解析：本题考查祈使句的用法。从题意“你不应该在课堂上说话”可知，这是建议对方不要做某事的，应该用祈使句。

　　答案：Don't talk

　　误区提醒

　　感叹句中what 和how的用法区别，是很多学生头疼的地方，实际上区分它们并不难，只要记住：有形容词直接加名词的地方，或只有名次的地方，用what，反之用how.

　　典型例题：____ strange clothes he is wearing!

　　A. What a B. What C. How a

　　解析：题中strange clothes是形容词直接加名词构成的名词短语，应该用what，clothes是不可数名词，不能加a.

　　答案：B
