2、令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句最常用于表达命令。祈使句因对象(即主语)是第二人称，所以通常都省略。祈使句的动词都为一般现在时，句末则使用句号来表示结束。如：Go and wash your hands. (去洗手。命令) Be quiet, please.(Please be quiet.) (请安静。请求) Be kind to our sister. (对姊妹要和善。劝告) Watch your steps. (走路小心。警告) Look out! Danger! (小心！危险！ 强烈警告) Keep off the grass. (勿践草坪。禁止) 祈使句也常把主语

3、“You”表达出来，使对方听起来觉得柔和些，如： _. (汤姆，你去告诉他。) (2) 表现形式: 肯定结构: Do型(即:动词原形(+宾语)+其它成分)。如:Please have a seat here. _.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. _. Be型(即:Be + 表语(名词或形容词)+其它成分)。如:_.要做一个好孩子！ Let型(即:Let + 宾语 + 动词原形 + 其它成分)。如:_让我来帮你。 否定结构: Do型和Be型的否定式都是在句首加dont构成。如:_! 不要忘记我！ Le

4、t型的否定式有两种:“Dont + let + 宾语 + 动词原形 + 其它成分”和“Let + 宾语 + not + 动词原形 + 其它成分”。如:Dont let him go. / Let him not go. 别让他走。 有些可用no开头， 用来表示禁止性的祈使句。如:_! 禁止吸烟！No fishing! _！ 用“let”的祈使句时，必须注意下列几点： (a)“let” 的否定句有二。如果宾语是第三人称用“Dont let.”；如果宾语是第一人称，则用“Let. not”，如： Dont let this type of things happen again. (b)“Let”

5、只适用于现在时态，可以有被动语态 (the passive voice)，如： Let the recalcitrant criminals be sent to prison. (c)“Let”后头除了是不带“to”的不定式动词 (The infinitive without “to”)之外，还可以是某些适当的副词，如out， in， down， alone等： Open the windows and let the fresh air in. _.(d) 用“Lets”时，把谈话者的对象包括在内；用“Let us”时，并不包括对方，如： Let us do it by ourselves

6、, will you? _？(3)高考回望祈使句通常用来表示命令、请求、禁止、建议、警告等语气，是高考的热点之一。分析历年高考试题，可以看出主要是对以下几个方面进行考查：(一)对祈使句谓语动词形式的考查 1._ it with me and Ill see what I can do. A. When left B. Leaving C. If you leave D.

7、aps youll like it. A Turning B Try C To try D Have tried 4._down the radiothe babys asleep in the next room.对策：牢记常见祈使句结构，注重标点符号的功用，排除非谓语动词的干扰(非谓语动词提前作状语，常用逗号与后面分开，说明后面情况发生的时间、原因、条件、目的等)如： 5_ late in the morning， Bob turned off the alarm. A. To sleep B. Sleeping C. Sleep D. Having slept 二.对祈使句的反意疑问句考
