1、初一英语重点句型综合解析课时五 祈 使 句 1.祈使句的定义及句式特征: 定义:祈使句是用来表示请求、命令、叮嘱、邀请、劝告或祝愿等的句子。它的特点是通常省略主语you,以动词原形开头,末尾可用句号或感叹号。祈使句没有疑问句的形式,一般只有肯定和否定两种形式。 Go and wash your hands. (表命令) Be quite, please. Be kind to your sister. Watch your steps. No parking. (表禁止) 2.肯定形式 1)以系动词be开头的祈使句,这种祈使句的常用结构: be+形容词 / 名词 Be quiet / quic

2、k! Be a good student! Be careful when crossing the street. 2)以实义动词开头的祈使句,这种祈使句的常用结构为: 动词原形+宾语。 Come in, please! Please open your books! Put them away! let型 Let him do it by himself. Let me help you. Lets go to the park. 3.否定形式来表示) 1)be型) Dont be careless! Never be late again next time! 注意:在这种句型中,be不

3、能省略 否定副词not不可置于be之后 2)do型 Dont believe him! Dont worry! Never do it again! 3)Let引起的祈使句有两种否定形式 a. Let+宾语+not+动词原形+其他 Let her not do that. Lets not think about it. Its only a waste of time. b. Dont+ let+宾语+动词原形+其他 Dont let Jim do that. Dont let us go, please. 4) 在公共场合的提示语中,否定祈使句常用“No名词 /V-ing形式”结构,表示“

4、禁止做某事”。例如: NO PHOTOS! 禁止拍照! No parking! 注意: 1). 在表达请求或劝告时,有时为了表示委婉的语气,可以在句首或句末please,但是如果please加在句末,应用逗号将其与前面的部分隔开。 Sit down, please. Please look after the twins. 2). 在意思比较明显的情况下,可以把谓语动词省略。 This way, please. 3). 有时为了加强语气,可以在动词前使用do. Do be careful!一定要小心! 4). 有时为了强调对方,也可加上主语you,人名或everybody, anybody等不

5、定代词。 You sweep the floor and I clean the window. Stand up, everybody. 5).有时为了明确向谁提出请求或发出命令,可加称呼语,但称呼语要与句子用逗号隔开。 Put the shirt on the bed, Jim. 4.祈使句的反意问句 祈使句的反意疑问句须按其句子结构及讲话人的语气来决定其疑问部分,通常有以下三种形式: 1).祈使句为肯定句式,其反意疑问句表示请求时,通常用will you;表示邀请、劝说时,用wont you。例如: Be sure to write to us, will you? 你一定要给我们写信,

6、好吗? Come to have dinner with us this evening, wont you? 今晚来和我们一起吃饭,好吗? 2).祈使句为否定句式,其反意疑问句通常只用will you。例如: Dont smoke in the meeting room, will you? 不要在会议室抽烟,好吗? 3). Let开头的祈使句构成反意疑问句时,除Lets用shall we外,其它均用will you。例如: Let the boy go first, will you? 让个那男孩先走,好吗? Lets take a walk after supper, shall we?

7、 晚饭后我们去散步,好吗? 5.祈使句的回答 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wont。 在回答具有否定意义的祈使句时,要注意两点: 形式一致(即Yes与will保持一致;No与wont保持一致) 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。例如: - Dont go out, please. Its raining heavily outside. 请不要出去。外面雨下得很大。 - Yes, I will. I have to meet my brother at the airport.

8、 不行,我得去机场接我弟弟。 6. 祈使句与陈述句的并列使用 祈使句后接陈述句时,须用连接词连接。如果祈使句与陈述句表示的是一种顺承关系时,要用并列连词and来连接;如果祈使句与陈述句存在一种否定条件关系时,要用并列连词or来连接。例如: Leave it with me and I will see what I can do. 把它留给我吧,我想想有没有办法。 Hurry up, or well be late. 快点,否则我们要迟到了。 7.祈使句与条件状语从句的连用 祈使句与条件状语从句连用时,条件状语从句可置于祈使句前或后。例如: Tell him to make a phone c

9、all to me if he comes here tomorrow. 如果他明天来这儿的话,叫他给我来个电话。 8.祈使句的强调形式 祈使句的强调形式通常在肯定祈使句式前加上助动词Do。例如: Do shut up! 快住口! 9.特殊形式的祈使句 在英语中,有些祈使句不是以动词原形来引起一个祈使句,而是以一个名词短语来充当,且后接一个带有并列连接词的分句。实际上,这个充当祈使句的名词短语相当于一个条件状语从句。例如: More water and the young trees couldnt have died. If you had given them more water, th

10、e young trees couldnt have died. 如果你给那些小树多浇点水,他们就不会死了。 10.运用祈使句的误区 祈使句往往容易与不定式、分词或条件状语从句相混淆。 _ your composition carefully, some spelling mistakes can be avoided. A. Having checkedB. Check C. If you checkD. To check 巩固练习: 一、单项选择: 1. Please _, theyre having a meeting. A. not be so noisyB. be quiteC. m
