高中英语祈使句用法总结

一、英语祈使句核心知识点解说

一、祈使句的定义

用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句最常用于表达命令，因此也常称为命令句，表达说话人对对方的叮嘱、劝告、希望、禁止、请求或命令等。祈使句一般以动词原形开头，无时态和数的变化，句末用句号或感叹号，用降调。

●祈使句的含义

1、表请求

例句：Pass me the sugar, please. 请把糖递给我。

2、表命令

例句：Put up your hands. 举手。

3、表建议

例句：Let’s have dinner together. 我们共进晚餐吧。

4、表邀请

例句：Come in and have a seat. 进来请坐。

5、表警告

例句：Hurry up or you will be late.抓紧点，不然你要迟到了。

6、表禁止

例句：Don’t touch the exhibits.不要触摸展品。

7、表叮嘱

例句：Be sure to get there before nine. 务必在九点前赶到那里。

8、表号召

例句：Workers of all countries, unite! 全世界工人阶级联合起来!

9、表祝愿

例句：Have a good trip. 祝你旅途愉快。

●祈使句的特点：

1、谓语大都是表示行为动作的动词或动词性词语，表示的动作是未然的。

2、主语一般是第二人称代词“你、你们”，往往省去。也有时用第一人称“咱们”作主语。国内外许多语法家认为不仅有第二人称的祈使句，还有第一、三人称的祈使句。从语义学方面进行分析研究，祈使句的主语实质上都是第二人称。

●祈使句的语调特点：

1.语音强度一般比陈述句重，书面上用感叹号表示。

2.句末用降调，较长句子的后半部分几个音节速度加快。

二、祈使句的分类

祈使句表请求、命令、叮嘱、邀请、劝告等。祈使句分为第二人称祈使句及第—、三人称祈使句两大类。

1、第二人称祈使句通常用来向听话者发出命令，提出要求或建议。这种祈使句的主语you通常不表示出来，而是以动词原形开头。

例句：Stand up!或Don’t worry about!

注意：如果说话时有多人在场，就得把主语表示出来，或加呼语，以便指明是向谁提出请求或发出命令。

例句：Mary clean the windows，and you boys wash the floor! 玛丽擦窗户，你们男孩子洗地板!

注意：有时将主语表示出来是为了加强语气或表示“不高兴”、“厌烦”、“鄙视”等情绪。如：Don’t you be late again! 你可别再迟到了!

2、第一、三人称祈使句是以第一人称和第三人称代词或者名词等作为祈使的对象，这类祈使句通常以let为引导词表建议。

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!

三、祈使句句型及表现形式

●肯定结构:

1、Do型(即: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型(即: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型(即:Let + 宾语 + 动词原形 + 其它成分)。如:Let me help you. 让我来帮你。

●否定结构:

1、Do型和Be型的否定式都是在句首加don't构成。如:Don't forget me! 不要忘记我!

Don't be late for school! 上学不要迟到!

2、Let型的否定式有两种:“Don't + 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:Don't let him go. / 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!No fishing! 禁止钓鱼!

四、祈使句的反意疑问句

1、基本原则

若陈述部分为祈使句，反意疑问句通常用will you, won’t you, would you等：

例句：Try to be back by two, won’t you? 设法两点之前回来，好吗?

注意：若陈述部分为否定式，则反意疑问句部分只用will you：

例句：Don’t forget to post the letter, will you? 请别忘了寄信。

注意：有时根据语境的需要，反意疑问句也可以用can you, can’t you 。一般说来，用will you, won’t you, would you 等构成的反意疑问句语气较委婉。

2、当祈使句为Let’s…时，反意疑问句总是用 shall we。

3、当祈使句为Let us…时，若表示请求，反意疑问句用will you，若表示建议，反意疑问句用 shall we。

例句：Let us know your address, will you? 请把你的地址告诉我们，好吗?

Let us go swimming together, shall we? 我们一起去游泳好吗?

注意：let’s…只表示建议，所以其后反意疑问句总是用shall we。而let us…既可表示建议请求，也可表示建议(较正式)，其后的反意疑问句要根据这两种不同情况分别使用will you和shall we。

4、当祈使句带有主语时，有时祈使句带有自己的主语，此时不要将其误认为是陈述句。

例句：You girls stand in the front row, will you? 你们女孩子站在前排，好吗?

注意：不要将这类祈使句误认为是陈述句，而误用don’t you这样的反意疑问句。

五、祈使句相关口令

祈使句无主语，主语you常省去;

动词原形谓语当，句首加don't否定变;

朗读应当用降调，句末常标感叹号。

　　初三英语上册知识点：Let引导的祈使句

　　由"let"带头的祈使句(Imperative Sentences)是个常见的动词句型，它的主要用法有下列三种：

　　 1.表示“建议”。

　　这个句型里的"let"后头紧跟着一个第一人称的代词宾语，如：

　　(1) Let me try.

　　(2) Let's do it.

　　(3) Let me go and look for it.

　　这个句型语气委婉，比直接的祈使句客气。试比较(4)a和(4)b:

　　(4) a. Don't disturb him.

　　b. Let's not disturb him.

　　(a)是直接命令，语气强烈，不如(b)温柔悦耳。

　　 2.表示“间接命令”或“愿望”。

　　这句型里的动词宾语是第三人称名词或代词，如：

　　(5) Let Robert take charge of the marketing department.

　　(6) Let her join our choir.

　　 3.表示“警告”、“蔑视”、“威胁”等。

　　这种祈使句里的宾语也是第三人称为主。除了口气凶悍之外，有时还语带讽刺，如：

　　(7) Let him try and he will expose his inability to work on his own.

　　(8) Let the invaders come and our armed forces will wipe them out in no time.

　　 用"let"的祈使句时，必须注意下列几点：

　　一、"let" 的否定句有二。如果宾语是第三人称用"Don't let……"(见例(9));如果宾语是第一人称，则用"Let……not" (见例(10))：

　　(9) Don't let this type of things happen again.

　　(10) It's raining now. Let's not go out until after the rain.

　　二、"Let"只适用于现在时态，可以有被动语态 (the passive voice),如：

　　(11) Let the recalcitrant criminals be sent to prison.

　　(12) Let all the dedicated capable staff be promoted.

　　三、"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：

　　(13) Let the puppy out.

　　(14) Open the windows and let the fresh air in.

　　(15) The room is too sunny. Let the blinds down.

　　(16) Let me alone, please.

　　四、用"Let's"时，把谈话者的.对象包括在内;用"Let us"时，并不包括对方，如：

　　(17) Let's try it, shall we?

　　(18) Let us do it by ourselves, will you?

　　从(17)里的"shall we"和(18)里的"will you"，不难知道前者包括听话人，后者并没有。

二、英语中祈使句是什么意思 英语中祈使句解释

1、祈使句（Imperative Sentence）是英语中的一个句式，也是用于表达命令、请求、劝告、警告、禁止等的句子。祈使句最常用于表达命令，因此在学校文法中也常称为命令句。

2、祈使句指的就是要求性语气的句子，句子内容通常都是表达要求对方去做某事，又或者是不要去做某事，因此祈使句所包含的个人情感色彩往往会比陈述句中表露出来的多得多，当用书面形式表达祈使句时，一般都会在末尾加上感叹号。

三、高中英语祈使句用法总结

　　祈使句是用来表示请求、命令、劝告或建议等语气的 句子 。它的主语多是You(通常不说出)。大家知道祈使句的用法是什么吗?

　　高中英语祈使句用法 总结

　　一、祈使句的分类

　　祈使句分为第二人称祈使句，第一、三人称祈使句，还有一些不定代词祈使句共三大类。

　　1.第二人称祈使句通常是用来向听话人发出命令、提出要求或建议的。这种祈使句的第二人称主语you通常省略，用动词原形开头。如：

　　Get out of here!滚开!

　　Look here!注意!

　　2.第一、三人称祈使句是以第一人称、第三人称或者名词等作为祈使句的对象，这类祈使句通常以let为引导词。基本结构：Let me go.但有时前面也可以加do,以加强语气。如：

　　Do let me go.一定让我去。

　　3.有时所表示的主语可以是everybody,somebody,anybody,nobody等不定代词。如：

　　Stand up,everybody!全体起立!

　　Give me a hand，anybody!帮我一把，任何人都行!

　　祈使句除用谓语动词表示外，还可用名词、形容词、副词等。如：

　　Help!救人!

　　Patience!要有耐心!

　　Careful!小心!

　　Quickly!快!

　　Hands up!举起手来!

　　二、祈使句的附加疑问句

　　祈使句之后可用附加疑问句，并不是与祈使句构成反意，而是加强语气，无论其前是否定还是肯定的祈使句，多用will you,表示一种客气的语气。如：

　　Don’t tell anyone,will you?你可不要告诉任何人啊。

　　但在肯定的祈使句之后有时也使用won’t you,多表示“提醒对方注意”。如：

　　Tell me the truth,won’t you?你可要告诉我实情啊。

　　以Let’s开头的祈使句，其附加部分为shall we或shan’t we;以Let us开头的祈使句，其附加部分为will you。试比较：

　　Let’s go out for a walk,shall we?

　　Let us have another try,will you?

　　三、祈使句的否定形式

　　1.对于第二人称的祈使句，只要在整个句子结构之前加Don’t或Never即可，即使祈使句有主语，也是如此。如：

　　Don’t you open the door!

　　Don’t be deceived by his looks!

　　不定代词的祈使句也是如此。

　　2.第一、三人称的祈使句的否定形式除了以Don’t开头之外，还可以把否定词not置于动词不定式之前，但有时这两种否定形式会有不同的意思，在交际中究竟采取哪种形式恰当，需要根据语境来决定。试比较：

　　Let him not come.It’s all the same to me.Don’t let him come.It’s dangerous here!

　　第一句话表明说话人语气冷淡，他来不来无所谓。而第二句话则表明了说话人的一种担忧，进而坚决要求他不要来。不同的语气和感情，通过两种不同形式的否定，表现得淋漓尽致。
