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 在句子里不能做谓语,也没有具体的含义。
行为动词:就是在句子里能充当句子成分,又具体的含义。 I am watching TV.
| 助动词 | 用途 | |
| be动词的各种形态(is\\am\\are\\was\\were) | 帮助动词 构成现在进行时:be +ving 构成被动语态:be+ved | 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 |
| do的各种形态(do\\does \\ did) | 帮助动词构成现在时态:v vs\\es 过去时态:ved | Eg1:I like dancing. like=like+do 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 I did not like dancing. Did you like dancing? |
| 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 | 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): | 帮助动词构成将来时态:will\\would+v | I will go home at five o’clock. |
| 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. |
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,在句子里能够充当句子成分。助动词是不具有实际意思,在句子里不能充当句子成分,只是帮助动词构成各种时态和语态
| 动词 | 做助动词 | 例 子 | 做行为动词 | 例 子 |
| do | 构成一般时态 助动词是do | I don’t like apple. 我不喜欢苹果。 | 翻译为“做” 后面跟宾语。 助动词是do | Eg: do homework 做家庭作业 do 是谓语动词, |
| be | 构成进行时 和被动语态 助动词是be | I am reading. 我正在读书 This book is bought. 这本书被买。 | 翻译为“是” 后面跟宾语。 助动词是be | I am a girl. 我是女孩。I am beautiful.我漂亮。 am是这个句子的谓语,翻译为“是”具有实际意思。 |
| have | 构成完成时 助动词是have | I have finished my homework. | 翻译为“有” 后面跟宾语。 助动词是do | Eg: I have many jobs. 我有很多工作。 Have是谓语动词,翻译为 “有” |
| need | need做助动词时是情态动词,表示“有必要”的意思 助动词是need | Eg: I need go home. need是情态动词,表示“有必要” Need you go home? Yes, I need. No, I needn’t. needn’t= need not | 表示“需要”,是及物动词后面要跟宾语。 助动词是do | Eg: I need you.我需要你 need=need+do need 是实意动词,在句中做谓语,表示“需要” Do I need you? Yes, I do. No, I needn’t. |
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 | 做题方法 | 例子 |
| 改写句子 | 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not。 变一般疑问句:只要把助动词提前。
二、但是若这些词后面是否是名词,说明他们是行为动词,它的助动词就是do。例子见上表。 | 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. 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 (当谓语动词是原形时,助动词就是do) He studies English well. studies=study+does (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。 |
| 用所给词组成句子 | 先把助动词放到句首,再找出主谓宾,按照句子结构排好,组后加上问号。 | 例1、 beautiful , a , she, pen, have 主语:名词、代词、数词 本题中可能是主语的:she, pen 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 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 ? |
