助动词do/does的用法专题 助动词do与does口诀 （一）(do ) 变句型，先观察，陈述句中动用原, 一般疑问do提前，否定don’t实动前。 （二）(does) 若是主语为三单，陈述句中动变形，一般疑问也简单， does放在句子前，否定doesn’t实动前，主动出现动还原。 总结： 含有实义动词的句子，进行句子转换时应借助于助动词do/does，主语是三单(he,she,it)时用does，其他用do。否定句在动词原形前加don’t /doesn’t，一般疑问句把do/does 提前,特殊疑问句由特殊疑问词+一般疑问句。 句子类型及结构 肯定句：主语+动词+其它。主语是三单，动词用三单 I like this blue sweater. Tom likes this blue sweater. 我喜欢这件蓝色的毛衣。Tom喜欢这件蓝色的毛衣。 Tom likes English. Tom喜欢英语。 I like this blue sweater. Tom likes English. 否定句：主+ don’t/doesn’t+动原+其它 I don’t like this blue sweater. 我不喜欢这件蓝色的毛衣。 Tom doesn’t like English. Tom不喜欢英语。 I like this blue sweater. Tom likes English. 一般疑问句：do/does提前，其它照抄不变（Do /Does+主+动原+其它），一人称变二人称。回答：Yes,主+do/does. No,主+ don’t/doesn’t. Do you like this blue sweaterYes, I do. / No, I don’t. 你喜欢这件蓝色的毛衣吗是的，我喜欢; 不，我不喜欢。 Does Tom like EnglishYes,he does. / doesn’t. Tom喜欢英语吗是的，他喜欢；不，他不喜欢。
be 动词、助动词、情态动词讲解（基础篇） 1、 用单数，反之用复数。 ◆ 句中含有be动词时： 肯定句：主语＋be ＋其他 否定句：主语＋be ＋not ＋其他 一般疑问句：Be ＋主语＋其他＋？ 特殊疑问句：疑问词(what / who / when / where)＋be ＋主语＋其 他＋？ I am a teacher. You are right. She is 16 years old. My father is at home. The students are playing games. My teacher was ill yesterday. There is a picture on the wall. There are two books on the table. ★ be 动词用法歌： 我用am，你用are，is 连接他她它。单数名词用is，复数名词全用are。 变疑问，往前提，句末问号莫丢弃；变否定，更容易，be 后not 莫忘记； 疑问否定任你变，句首大写莫迟疑。 ★ be 动词作谓语，它后面一般跟名词、形容词或介词短语。她个子很高。 她在教室里。她是一个高个子的女孩。 2、助动词的用法。 英语句子按正常语序是“什么人或事物” + “做什么”，即，我们常说的“主语+ 谓语+ 其他” 。 ①主语为I 或复数名词、代词时：肯定句：I / We / They / The students
＋动词原形＋其他＋。 We watch TV every night. 变否定：主语＋don't ＋动词原形＋其他＋。 We don't watch TV every night. 一般疑问句Do + 主语+ 动词原形+ 其他+ ？ Do you watch TV every night? Yes, we do. / No, we don 't. 特殊疑问句：疑问词+ do + 主语+ 动词原形+ 其他+ ？ How often do you watch TV? ②主语为单数名词或代词时：肯定句：主语+ 动词第三人称单数形式 + 其他+ 。 He watches TV every night. 否定句：主语+ doesn't+动词原形+其他+。 He doesn't watch TV every night. 一般疑问句：Does + 主语+ 动词原形+ 其他+ ？ Does he watch TV every night? Yes, he does. / No, he doesn 't. 特殊疑问句：疑问词+ does + 主语+ 动词原形+ 其他+ ？ How often does he watch TV? ★主语为单数或不可数名词，谓语要用单数第三人称，反过来，看见动词用了单数第三人称，可以推知主语是单数或不可数名词。 ( )1. How __ ______ your dad help at home? A. do B. does C. is ( )2. ______ goes bad easily in summer. A. Milk B Apples C. Cakes ③过去时的句式（当句子时态为过去时时，动词用过去式，不受主语单复数的影响） 肯定句：主语+ 过去式+ 其他+ 。 He / We got up early every morning last year. 否定句：主语+ didn't + 动词原形+ 其他+ 。 He / We didn't get up early every morning last year. 一般疑问句：Did + 主语+ 动词原形+ 其他+ ？ Did he / you get up early every morning last year? Yes, he

be动词、一般动词和助动词 一、be动词、一般动词的现在式 （1）be动词的现在式—am/are/is a.是（表状态） We are happy.—我们很高兴 b.在（表存在） She is in America.—她在美国 含be动词（am/are/is）的肯定句变成否定句时，在be动词后加not即可。 肯定句：主语+am/are/is… 否定句：主语+am/are/is+not… He is a good baseball player. 他是一个好棒球员 （否定句）He is not a good baseball player. = He’s not a good baseball player. = He isn’t a good baseball player. 含be动词（am/are/is）的肯定句变成疑问句时，将be动词拿到主语前，句尾加？即可。肯定句：主语+am/are/is… 疑问句：Am/Are/Is+主语…？ 1.That is his camera. 那是他的相机 （疑问句）Is that his camera?
2.The girl is a junior high school student. 那女孩是初中生 （疑问句）Is the girl a junior high school student? 动词开头的疑问句为一般疑问句，可用yes或no回答，而答句中的主语 （问句）Am/Are/Is+主语…？ （答句）Yes,主语+am/are/is No,主语+am/are/is not 1.Is that man your math teacher? Yes, he is./No,he is not. 2.Are you eating your lunch? Yes, I am./No, I’m not. （2）一般动词的现在式 凡是日常生活中具体的动作，如：eat-吃饭，walk-走路及抽象的动作如：like-喜欢，think-思考…皆为一般动词 a.大部分动词加s works/plays b.一般动词词尾为o/s/sh/ch时。加es go-goes/wash-washes/watch-watches c.一般动词词尾为字音+y时，去y加ies cry-cries/study-studies have和has has为have（有，吃）的单数形式 They have a lot of money.
归纳起来, do ,does 的用法有四方面: 一.用作一般的动词,均可.do是一不规则变化的动词(do ,did,done). do,据人称和单复数的不同而有字形的变化.第一第二人称,以及第一.二.三 人称的复数时,都用do . 第三人称单数时,用does( he does she does it does ) 例如: I do my homework on Sunday. You do your homework on Sunday. We do our homework on Sunday. You do your homework on Sunday. They do their homeworkon Sunday. He does his homework on Sunday. She does her homework on Sunday. 二.当助动词用,用它来构成疑问句.这时它本身没有实义,只是一个构成疑问句的符号而已.这种用法时,它随人称和数的变化规则与上述相同.只是把它放到句子的最前面(句首).例如: Do I ............... Do you ............. Do we .............. Do you ............. Do they ............ Does he ............ Does she ........... Does it ............ 三.当助动词用,与not 连用使句子构成否定句.其随人称和数的变化规则与上述相同.例如:
I do not .................. (do not 可简化为don't ,下同) You do not ................ We do not.................. You do not................. They do not................ He does not................ (does 可简化为doesn't,下同) She does not............... 四.当作助动词,本身在句子中无实义,只是加强句子中动词的语气.其随人称和数的变化同上.例如: Do write to me.(一定写信给我!) Never do I see such a fool.(我从来没见过这样的蠢才.) She does come.(她的确来了.) * * * * * * 按词性, do 还可以用作名词.其意是"欺骗";"宴会,宴请".例如: It's all a do.(完全是欺骗.) We have got a do on to-night.(家里今晚请客.)
协助主要动词构成谓语的词叫助动词（Auxiliary Verb），也叫辅助动词。 被协助的动词称作主要动词（Main Verb）。 助动词用来构成时态和语态。 例如： He does not speak English well.（他英语讲得不好。） 句中的does是助动词，既表示一般现在时，又与not一起构成否定形式。 A dog is running after a cat.（一条狗正在追逐一只猫。） 句中的is 是助动词，和run的现在分词一起构成现在进行时。 Did he have any milk and bread for his breakfast ?（他早餐喝牛奶、吃面包吗？） 句中的did是助动词，既表示一般过去时，又和动词have一起构成疑问。 助动词具有语法意义，但没有词汇意义，不可单独作谓语。它没有对应的汉译。 例如：He doesn't like English. 他不喜欢英语。 （does是助动词，无词义；like是主要动词，有词义) 最常用的助动词有：be，have，has，do，does，shall，did，will，should，would 等。
助动词可以协助主要动词构成时态或者语态，也可构成疑问句和否定句，构成否定句时与否定副词not连用。 2. 半助动词： 在功能上介于主动词和助动词之间的一类结构，称为半助动词。 常见的半助动词有： be about to，be due to，be going to，be likely to， be meant to，be obliged to，be supposed to，be willing to，

1.be动词（am/is/are） 主语be动词（原形）be动词（过去式） I am was He/she/it is was We/you/they are were 口诀：我用am, 你用are，is用在他她它，所有复数全用are ①肯定和否定句 I am (not) from London. He is(not) a teacher. She is(not) in the dining room. My hair is(not) long. Her eyes are(not) small. ②一般疑问句 Am I a Chinese?——Yes, you are. /No, you aren’t. Is the cat fat? ——Yes, it is. /No, it isn’t. Are they American?——Yes, they are. /No, they aren’t. 表示疑问，一般回答只有两种可能Yes或No，句中没有疑问词。 如何将一个肯定的陈述句改为否定句： 1、看句中有无be动词，如有，把be动词提到句首即可。 2、看句中有无情态动词，如有，把情态动词提到句首即可。 3、如上述二者都没有，就应把助动提到句首。分四个步骤： （1）肯定陈述句中本来是没有助动词的，要加上去，位置在主语（某人/某物）后，动词前。 （2）确定助动词用do、does还是did，根据句中动词，动词是原形的助动词就用do，动词是第三人称单数的助动词就用does，动词用过去式的助动词就有did。
（3）把助动词后提到句首。 （4）原句中动词假如发生变化就要恢复成原形。 有some的要考虑是否要用any 2.助动词（do/does/did） 主语助动词（原形）助动词（过去式）否定形式I/We/you/they do did don’t/didn’t He/she/it does did doesn’t/didn’t ①.Do+非第三人称单数＋动词原形…? do/don't you/they have...?—Yes, I do/No, I don’t. ②.Does+第三人称单数＋动词原形…? does/doesn't he/she have...?—Yes, he does./No, he doesn’t. ③Did+所有主格＋动词原形…? did/didn't you/he/she/they go to school?—Yes, i did./No, I didn’t. 3.特殊疑问句 表示疑问，有疑问词开头，回答有很多种可能。常用疑问词：What、Who、When、Which、Why、Whose、How ※What do you/they/we…+动词原形？I/They/We+动词原形… What does he/she/it…He/She/It +(动词＋S)….
