英语祈使句讲法及练习和答案

祈使句一、祈使句（Imperative Sentence）定义：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。

例：Go and wash your hands. （去洗你的手。

——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，已如感叹句）No parking. （禁止停车。

——禁止）二、祈使句的否定形式祈使句的否定形式是在整个结构之前加don’t或never。

如：Don’t you be nervous!你不要紧张!以let为引导词的祈使句的否定形式通常是在Let’s或Let us／me 后加not。

如：Let’s not waste our time arguing about it! 咱们别浪费时间争论这事了! Let’s not say anything about it! 这事咱们谁也别说!但英式英语也用这样的表达：Don’t let’s say anything about it. 三、祈使句的反意疑问句1．祈使句的反意疑问部分为肯定形式，要用will。

如：Pass me the book，will you?2．Let’s表示第一人称的祈使句，反意疑问句为“Shall we?”。

如： Let’s go for a walk，shall we?Let’s forget it，shall we?3．Let me和Let us 表示第二人称的祈使句，反意疑问句为“will you?”。

如：Let us go for a walk，will you?4．其它行为动词引起的祈使句，无论其陈述部分是否定还是肯定的祈使句，多用“will you?”，表一种客气的语气。

祈使句的回答
• 一.祈使句的动作通常是表示将来发生的动作，所以回答祈使句时，一般用will或 won’t在回答具有否定意义的祈使句时，要注意两点：一是形式一致，即Yes与will保持一致；No与won’t保持一致。 • 二是意思相反，即Yes是不的意思；No是“ 是”的意思。在回答时，要注意分析上下文语境中所提供的条件。 • 三，对于let us或let’s的表示建议的祈使句常用OK. /All right. /Good idea.来回答
