一般疑问句=助动词+陈述句剩余部分 否定句＝找出助动词，在助动词后加not
一、 助动词：帮助动词构成时态、语态、感情色彩和否定疑问句。它包括 be动词 , do的各种形态， have的各种形态， will等情态动词。
I am watching TV. am 在句子里不能独立做谓语，也没有具体的含义。
行为动词：就是在句子里能独立充当句子成分，又具体的含义。 I am watching TV. 助动词 用途 Ｅg: I am a girl. Am I a girl? Yes, you are.\\ No, you’re not. ’re not= are not She is a girl. Is she a girl? Yes, she is.\\No, she is not. You are a girl. Are you a girl? Yes, I am.\\ No, I’m not. I am watching TV. Am I watching TV? Yes, you are. \\No I `m not Ｅ帮助动词构成现在时态：v vs\\es g1:I like dancing. like=like+do 过去时态：ved I do not like dancing. Do you like dancing? Ｅg2:She likes dancing. likes=like+does She does not like dancing. Does she like dancing? Ｅg3:I liked dancing. liked=like+did have的各种形态（have\\has\\had） 帮助动词构成完成时态： 现在完成时态：have\\has+ved 过去完成时态：had+ved I did not like dancing. Did you like dancing? Ｅg1： We have finished our homework. She has finished her homework. Has she finished her homework? Yes, she has.\\No, she hasn’t. will的各种形态(will\\would): can\\may\\must\\shall\\should\\will\\would\\need等情态动词 它们不帮助动词构成各种时态或语态，但是它表达动词的一定的感情色彩。而且，它们后面的动词用原型。也就是说，不考虑这个动词的时态和主谓一致。 I can do it You should go home. 帮助动词构成将来时态:will\\would+v I will go home at five o’clock. be动词的各种形态帮助动词 （is\\am\\are\\was\\wer构成现在进行时：be +ving e） 构成被动语态：be+ved do的各种形态（do\\does \\ did）
二、 有的助动词既可以做助动词又可以做行为动词：
be动词可以做行为动词,也可以做助动词。
行为动词是有实际意思，表示具体的动作，在句子里能够独立充当句子成分。助动词是不具
动词 do 助动词是do be 构成进行时 和被动语态 have 助动词是be 构成完成时 助动词是have need need做助动词Eg: I need go home. 时是情态动词，need是情态动词,表示表示“有必要”“有必要” 的意思 Need you go home? 助动词是need Yes, I need. No, I needn’t. needn’t＝ need not
I am reading. 我正在读书 This book is bought. 这本书被买。 I have finished homework. 有实际意思，在句子里不能独立充当句子成分，只是帮助动词构成各种时态和语态 做助动词 例 子 做行为动词 例 子 构成一般时态 I don’t like apple. 我不喜欢苹果。 翻译为“做” Eg: do homework 做家庭作业 后面跟宾语。 do 是谓语动词， 助动词是do 翻译为“是” I am a girl. 我是女孩。I am beautiful.我漂亮。 后面跟宾语。 am是这个句子的谓语，翻译为“是”具有实际意思。 助动词是be my 翻译为“有” Eg: I have many jobs. 我有很多工作。 后面跟宾语。 Have是谓语动词，翻译为 “有” 助动词是do 表示“需要”，Eg: I need you.我需要你 是及物动词后 need＝need+do 面要跟宾语。 need 是实意动词，在句中独立做谓语，表示 “需要” 助动词是do Do I need you? Yes, I do. No, I needn’t. 三、 学会通过助动词来判断谓语动词，来帮助读懂句子。
1、 四类助动词，只有do是包含在谓语动词里的，其它的三个都是在谓语动词前面的。 2、 很多助动词既可以做助动词又可以做实意动词。当做助动词的时候，后面跟动词。当
做行为动词的时候，后面跟名词。
四、 考题类型： 考题类型 改写句子 做题方法 一、先看有没有be的各种形式、have的各种形式或情态动词，没有就说明这个句子的助动词是do。 因为在句子里助动词的位置是：be的各种形式、have的各种形式或情态动词在谓语动词的前面，变否定例子 be的各种形式、have的各种形式或情态动词在谓语动词的前面。 He is going to see his uncle this afternoon. He is not going to see his uncle this afternoon. Is he going to see his uncle this afternoon. I have finished my homework. I have not finished my homework. Have you finished your homework. Da Shan can speak Chinese well. 句：只要在它们后面直接加not,而助动词do常隐藏在谓语动词里的。这时要先把助动词找出来，提前，再加Da Shan can not speak Chinese well. Can Da Shan speak Chinese well. 助动词do常隐藏在谓语动词里的。这时要先把助动词找出来，提前，再加not。 I study English well. study=study＋do not。 变一般疑问句：只要把助动 (当谓语动词是原形时，助动词就是do) 词提前。 He studies English well. studies＝study+does 二、 但是若这些词后（当谓语动词后面加了-s\\-es，助动词就是does） He studied English well. studied＝study+did (当谓语动词后面加了-ed,助动词就是did) He does not study English well. 把谓语动词提前，动词用原形，再not。 面是否是名词，说明他们是行为动词，它的助动词就是do。例子见上表。 用所给词先把助动词放到句首， 例1、 beautiful , a , she, pen, have 组成句子 再找出主谓宾，按照句主语：名词、代词、数词 本题中可能是主语的：she, pen 子结构排好，组后加上谓语：行为动词、be动词 本题中动词是：have “有” 定语：形容词 本题中定语是：beautiful 问号。 主谓宾： she have pen. 很明显beautiful 和 a 都是用来修饰 pen. 答案为： She has a beautiful pen. 例2、 he, rice, does, for , lunch, have ? 主语：名词、代词、数词 本题中可能是主语的： he, lunch, rice 谓语：行为动词、be动词 本题中动词是：have “有”, for 很明显 have 的宾语是 rice 介词for 的宾语是 lunch. 答案为： He have rice for lunch. Does he have rice for lunch ? 五、 作业
