专题十二 祈使句、感叹句
一、祈使句
(一)、祈使句的结构及用法
祈使句表请求、命令、叮嘱、邀请、劝告等。主语通常被省略，谓语动词用原形，句末用感叹号或句点。
1. 肯定的祈使句
(1)动词原形+其他
如： Stand up, please. = Please stand up. 请起立。
但有时会在句首加上主语或加呼语，以便指明是向谁提出请求或发出命令。呼语常与句子隔开，动词仍然用原形。
如： Mary， clean the windows!And you boys，wash the floor!
(2)Be + adj.
如：Be careful! = Look out! = Take care!
(3)Let's + 动词原形
如：Let’s go to school together.
2. 否定的祈使句
(1) Don't + 动词原形
如： Don't stand up. Don't be careless. Don't let them play with fire.
(2) Let's ( let sb ) + not + 动词原形
如： Let's not say anything about it.
3.祈使句的反意疑问句
(1) 肯定祈使句的反意疑问句反问部分用will you 或won't you。
如： Please open the door, will/ won’t you?
(2) 否定祈使句的反意疑问句反问部分只用will you。
如： Don't be late again, will you?
(3) 以let's开头的祈使句反意疑问句反问部分用shall we，let us开头的祈使句的反意疑问句的反问部分应为will you或won't you.
如：Let us stay here, will/ won't you?
Let's turn on the TV, shall we?
4. 特殊形式的祈使句。祈使句除用谓语动词表示外，还可用名词、副词、动词短语等表示。如：Help! Patience! Quickly! Hands up!
5. 祈使句的强调形式。有时为了加强语气，可以再动词前加上do，表示“务必，一定”。
如：Do be careful!
(二)、祈使句用于两个重要句型中
1.“祈使句+and+表结果的陈述句”用来叙述肯定的条件。
2.“祈使句+or(else)+表结果的陈述句”用来叙述否定的条件，or(else)表示“否则;要不然”。
如：Hurry up , and you’ll catch the train. (=If you hurry up，you’ll catch the train.)
Hurry up，or you’ll miss the train.(=If you don’t hurry up，you’ll miss the train.)
二、感叹句
(一)感叹句的结构及用法
感叹句是抒发强烈感情的句子，如欢乐、兴奋、惊奇、愤怒、悲伤等，书面语中句末用感叹号。常由what或者how引导,都表示“多么”。
1、 what引导的感叹句 what修饰名词或名词短语，有以下两种形式：
(1)What+a(an)+(形容词)+单数可数名词+(主语+谓语)!
如： What a nice girl (she is)!
What an interesting movie(it is)!
(2)What+(形容词)+可数名词复数或不可数名词+(主语+谓语)!
如：What kind women they are!
What nice music/bad weather/good news(it is)!
2、how引导的感叹句 how用来修饰形容词、副词或动词。其结构有：
(1)How+形容词(副词)+主语+谓语!
如：How hard the workers work!
How clever the girl is!
注意：当how修饰动词时，动词不跟着感叹词提到主语之前。
如：How fast the runner runs!
(2)How +形容词+ a +名词+ 主语+谓语。
如：How clever a boy he is!
(二)特殊形式的感叹句
1、在口语中常用省略句，有时只用一个词或词组。
如：Great ! How cold ! Look out! What a fool! What a pity! My goodness!
2、Here/There开头的感叹句：
(1).Here/There+主语(代词)+谓语
如：Here he comes!
(2).Here/There+谓语+主语(名词)
如：Here comes the bus!
