小学英语助动词用法归纳

助动词(Auxiliary Verb):协助主要动词构成谓语动词词组的词。自身没有词义,不可单独使用。

主要动词(Main Verb):是被协助的动词,构成时态和语态。

He doesn't like English. 他不喜欢英语。(doesn't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, do, shall, will, should, would 等。

基本助动词只有三个:be, do, have

他们没有词汇意义,只有语法作用,如协助构成进行时,完成时,被动态,否定句,疑问句等。

一、be 动词的用法

既可作系动词,又可作助动词,做助动词有人称和数的变化,第一人称用am,第二人称及复数用are,第三人称及单数用is,am,is 过去式

为was, are的过去式为were,它与现在分词构成进行时态和过去分词一起构成被动语态。

a. 表示时态be+doing(现在分词)表示现在进行的动作

He is singing. 他正在唱歌。

b. 表示语态be+done(过去分词)表被动语态

He was sent to England. 他被派往英国。

c. be+to do(动词不定式)表示计划安排命令。

We are to plant trees next week. 下周我们将要去植树。

You are to explain this 。对此你要做出解释。

二、do的用法

Do主要帮助实意动词构成否定和疑问句,后跟动词原形,有时放在实意动词前起强调作用,还可代替前文出现的动词,避免重复。Do 有人称和数的变化,第一、二人称及复数用do,第三人称及单数用does,过去式为did。

1)构成一般疑问句。DO +主语+动词原形+其他

I like singing 变为疑问句为Do you like singing ?

2)do + not 构成否定句。主语+do +not +动词原形。

I do not want to be criticized.我不想挨批评。

He doesn't like to study.他不想学习。

Many students didn’t know the importance of English before.过去好多学生不知道英语的重要性.

3)构成否定祈使句。

Don't go there.不要去那里。

Don't be so absent-minded.不要这么心不在焉。

说明:构成否定祈使句只用do,不用did和does。

4)放在动词原形前,加强该动词的语气。

Do come to my birthday party please.请一定来参加我的生日宴会。

I did go there.我确实去那儿了。

I do miss you.我确实想你。我真想你了!

5)用作代替动词。

---- Do you like Beijing?--你喜欢北京吗?

---- Yes, I do.No,I don’t.--是的,喜欢。(do用作代动词,代替like Beijing.)

He knows how to drive a car, doesn't he?他知道如何开车,对吧?

三、have 的用法

Have+过去分词构成完成时态

I have studied english for a long time .

情态动词的基本用法归纳

情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。情态动词无人称和数的变化;不能单独使用,必须与其后的动词原形构成谓语。

一、can, could

1) 表示能力

Mary can speak three languages.

Can you skate?

此时可用be able to代替。Can只有一般现在时和一般过去式;而be able to则有更多的时态。

I’ll not be able to come this afternoon.

当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。如:

He was able to go to the party yesterday evening in spite of the heavy rain.

2) 表示请求和允许。

-----Can I go now?

----- Y es, you can. / No, you can’t.

此时可与may互换。在疑问句中还可用could,might代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。

---- Could I come to see you tomorrow?

---- Yes, you can. ( No, I’m afraid not. )

3) 表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。

Can this be true?

This can’t be done by him.

How can this be true?

二、may, might

1) 表示请求和允许。might比may语气更委婉,而不是过去式。否定回答时可用can’t或mustn’t,表示“不可以,禁止”。

----Might/ May I smoke in this room?

---- No, you mustn’t.

---- May/Might I take this book out of the room?

---- Yes, you can. (No, you can’t / mustn’t. )

用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。

2)用于祈使句,表示祝愿。

May you succeed!

3) 表示推测、可能性(不用于疑问句)。

might不是过去式,它所表示的可能性比may小。

1.He may /might be very busy now.

2.Your mother may /might not know the truth.

三、must, have to

1) 表示必须、必要。

You must come in time.

在回答引出的问句时,如果是否定的,不能用mustn’t(禁止,不准),而用needn’t, don’t have to(不必).

---- Must we hand in our exercise books today?

---- Yes, you must.

---- No, you don’t have to / you needn’t.

2) must是说话人的主观看法,而have to则强调客观需要。Must 只有一般现在时,have to 有更多的时态形式。

1.he play isn’t interesting, I really must go now.

2.I had to work when I was your age.

3) 表示推测、可能性(只用于肯定的陈述句)

1.You’re Tom’s good friend, so you must know what he likes best.

2.Your mother must be waiting for you now.

四、shall, should

1)shall +动词原形表示将来时态

Shall we go shopping tomorrow?

2) shall 用于第一人称,征求对方的意见。

What shall we do this evening?

shall 用于第二、三人称,表示说话人给对方的命令、警告、允诺或威胁。

1. You shall fail if you don’t work hard.(警告)

2. He shall have the book when I finish it.(允诺)

3. He shall be punished.(威胁)

六、will, would

1) 表示请求、建议等,would更委婉。

Would you like a cup of coffee? 你想要一杯咖啡吗?

2)will +动词原形表将来时态

He will come back next month . 他下个月将会回来。

3)表示意志、愿望和决心。

1. I will never do that again.

(完整版)助动词用法及练习

be动词,情态动词,助动词do/does的用法区别及练习 助动词,顾名思义就是帮助动词完成疑问及否定的,本身没有什么含义。主要的助动词有be,do,will,have等,其用法详述如下: 一、⑴由连系动词am,is,are构成的句子:变一般疑问句时把am,is,are提到句子的前面,句尾用问号即可。变否定句时直接在am,is,are后面加not即可。例如: 肯定句:He is a student. 一般疑问句: Is he a student? 否定句: He is not a student. 画线提问: 对he提问: Who is a student? 对a student 提问: What is he? (2)was 是am,is的过去式,were是are的过去式,若句子中有以上两词时,变疑问句及否定句方法与(1)相同。 二、(1) 由情态动词can, may,will ,shall等构成的句子: 变一般疑问句时把can, may,will ,shall提到句子的前面,句尾用问号即可.变否定句时直接在can,may,后面加not即可. 例如: 肯定句: She can swim. 一般疑问句: Can she swim? 否定句: She can not swim. 画线提问: 对she提问: Who can swim? 对swim提问: What can she do?

He plays football after school. 一般疑问句: Do they play football after school? Does he play football after school? 否定句: They don't (do not) play football after school. He doesn’t’ play football after school. 画线提问: 对they/he提问: Who plays football after school? 对play football提问: What do they do after school? What does he do after school? 对after school提问: When do they play football? When does he play football? (2)did是do和did的过去式,变一般疑问句时把did放在句子前面. 变否定句时把didn’t 放在动词的前面, 要注意观察动词的形式并对号入座。一般疑问句和否定句的动词都要变回原型。

Be动词和助动词用法辨析

Be动词和助动词用法区别其实be动词也是助动词(auxiliary verbs)。 英语动词大致可分为三种:助动词(auxiliary verbs),情态动词(modal verbs),实意动词(full verbs)。 助动词(auxiliary verbs):do,be,have。没有实意,“帮助”别的动词,表示时态,否定和提问。情态动词(modal verbs):can,must,may。也是“帮助”别的动词,但是有自己的实意。实意动词(full verbs):play,run,think。其他有实意的动词。 be动词可用作助动词(auxiliary verbs):1,be+Ving:所有的进行时态,如:2,be+过去分词:被动式。 be动词也可用做实意动词(full verbs):be[bi]v.有;在;是。 你这样想,一个句子里要有动词吧。再看看它们的名字,“be 动词”和“助动词”, 先说“be动词”,(1)这名字里有动词,说明他是动词,句子里有他就不会有别的动词(除非这些动词以别的形式出现,这是后话)了,(2)“am,is,are,was,were”叫be动词,是因为他们是be的不同形式 再说“助动词”,(1)一定要注意“助”,是帮助的意思,说明他不是动词,只是起到了辅助的作用,所以,他们就一定要与动词同时出现。[记住啊,他们离不开动词,但是动词没有他们也是可以的]

(2)did,do,does只是do的不同形式,根据你所需要的时态来选择(1)用于肯定句,否定句和疑问句 am:第一人称单数(即只与I连用),用于现在时(一般现在,现在进行,只要那时态中是现在的就行)eg:①I am a girl.一般现在时②I am eating an apple.现在进行时 ③I am going to do my homework.[be going to表将来,将来中只有这一种] is:第三人称单数,用于现在时(一般现在,现在进行,只要那时态中是现在的就行)(it就不举例了)eg:①She/He is a girl/boy.一般现在时②He/She is eating an apple.现在进行时③He/She is going to do his homework.[be going to表将来,将来中只有这一种] are:第二人称单数,所有人称复数,用于现在时(一般现在,现在进行,只要那时态中是现在的就行)eg:①You are a girl.
