be动词的用法

初中英语动词知识点:Be动词定义及用法

Be动词有三个,am,is还有are。我用am,你用are,s跟着他她它,复数全部都用are。如果遇到过去时,was来把am,is替,were来把换掉动词are。下面是我为您收集整理的初中英语动词知识点:Be动词定义及用法,供大家参考!

初中英语动词知识点:Be动词的定义

do和be动词的用法区别。

Be 动词就是(am,are,is)句子中如果没有实意动词(例如:write,buy)之类的动词,就直接在主语后面加Be动词。而如果是句子中有实意动词,那么如果你要改为一般疑问句,就要借助DO(do也称为助动词),例如:I study.

改为一般疑问句:Do you study ?

顺口溜:be氏三朵花, am, is还有are,

我(I)恋am, 你(you)恋are,

is跟了他(he)她(she)它(it),

单娶is, 复娶are。

详细讲解:

英语的be 动词是个用法比较复杂的动词。复杂的原因有两点:

1、除了原形的be 之外,对于不同人称代词以及单数名词和复数名词,be 会有各种变化形式和缩写形式。概括一下有七种形式:be,am,is,are,was,were,been,being。绝巧它们与人称代词和名词单、复数的搭配关系是:

现在时 I am,you are,he/she/it/ is,we/you/they are;名词举宏亏单数、不可数名词用is,复数用are。

缩略式正神 I'm,you're,he's,we're,you're,they're

否定缩略式 I'm not,isn't,aren't

过去时 I was,you were,he/she/it/ was,we/you/they were;名词单数、不可数名词用was,复数用were。

否定缩略式 wasn't,weren't

过去分词 been

现在分词 being

2、在句子中,be有两种主要作用:一是作为系动词(The Linking Verb),本身可以作用谓语动词;二是做为助动词(The Auxiliary Verb),与谓语动词一起构成各种时态和被动语态等。

初中英语动词知识点:Be动词的用法

一、be 动词做系动词

1、系动词 表语”的结构

当be 动词做系动词使用时,主要构成“系动词 表语”的结构,在句子中做谓语。表语可以是名词、形容词、副词、介词短语等。例如:

The man is a science teacher.

Mary's new dresses are colourful.

Mother is in the kitchen now.

I have been there before.

They shall be here at 10:00 tommorow.

That can't be true.

You are not being very polite.

Your brother is being very annoying this evening

2、be 动词的一般疑问句,方法是把be 移到主语前面,也可说成是移到句首。

Is the man a science teacher? Yes, he is. / No, he isn't.

Are Mary's new dresses colourful? Yes, they are. / No, they aren't.

Was mother in the kitchen then? Yes, she was. / No, she wasn't.

Were you at home the day before yesterday? Yes, I was. / No, I wasn't.

Was she late this morning? Yes, she was. / No, she wasn't.

3、be 动词用在特殊疑问句

在特殊疑问句里,be 动词仍然移到主语前面,但特殊疑问句是以特殊疑问词开头的,所以be 动词只能说是移到主语前面,或者说是在特殊疑问词的后面。例如:

Whose bike is broken? Xiao Ming's bike is.

Who was singing in the room? Mr. Zhang was.

Where are you from? I am from Wuhu.

What class were you in? We were in Class 2.

How old is Tom? He is ten.

4、be 动词的否定句

be 动词做谓语时,它的否定形式是在be 后加not,并且可以缩写。例如:

It is not sunny today.

Tom and his friends are not in the park.

You were not nine years old when I went to the university.

He was not often late for his class when he was a student.

I wasn't here yesterday.

My parents weren't at home last Sunday.

5、be 动词的祈使句

be 动词的祈使句有肯定和否定两种形式。肯定形式是以be 动词开头,而否定形式或强调句形,要加don't 或do。例如:

Be careful!

Be a good boy!

Don't be silly!

Don't be a fool!

Do be obedient!

Do be careful.

二、be 动词做助动词

助动词be 有两个基本用法,一是与谓语动词一起构成各种时态,二是构成被动语态。

“be 现在分词组”成各种进行式时态。例如:

Tony's maid is washing his new car.

The children are playing in the field.

Samuel was eating when I came in.

We have been living here since 1959.

This time next day they will be sitting in the cinema.

三、注意事项

英语句子中,为了表达时态或被动语态的需要,常常会出现几个助动词连在一块儿使用。也就是说,助动词be会和其它助动词一起使用。这时候,整个句子的一般疑问句和否定句,就不一定是对be 进行变化了,而是以第一个助动词为主进行变化。即哪个助动词在先,就以它为主进行变化。例如:

[肯定句] All the wonderful birds can be found in our Bird Park. (助动词有两个:can be )

[疑问句] Can all the wonderful birds be found in our Bird Park? (移第一个can)

[否定句] All the wonderful birds can not be found in our Bird Park. (在第一个can 后加not)

[肯定句] I have been there before. (两个助动词:have, been )

[疑问句] Have you been there before?

[否定句] I have not been there before.

[肯定句] I shall be having my supper at six tomorrow evening. (两个助动词:shall, be )

[疑问句] Will you be having my supper at six tomorrow evening?

[否定句] I shall not be having my supper at six tomorrow evening.

四、助动词be,无词义,辅助主要动词一起在句中作谓语动词。用法如下:

1. be doing:构成进行时态,有现在和过去两种进行时态。如:

The girls is reading and copying the new words now.

Young Tom was always asking questions and trying out new ideas.

2. be going to do,表示“打算或将要做某事”,be有现在和过去两种形式。如:

We are going to plant trees in the park.

I didn’t know if she was going to come here.

3. be to do,表示“按计划安排将要做某事”。如:

The new shop is not to be opened till next Monday. One night an angel came to

Mary and told her that she was to have this special boy.

五、there be

there be句式为:there be 主语部分 状语部分,表示“某处存在某物”,be常用现在时,过去时和将来时等。如:

Oh, cool! And there are many things to see. There is even a deer park in Sanya.

There are about 80 pyramids in Egypt.

Will there be a football match in your school next week?

六、实义be

可以将be视为实义动词,因为它具有实际的词义,如“成为;做;发生;举行;逗留;到达”等。如:His daughter wants to be a doctor for animals in her twenties.Kates birthday party

will be at half past six this evening.Jim has been in China for

morethan two years, but he has not yet been to Yichang.

be动词的用法~!

一、用法

aux.(助动词)

be用作助动词时可与动词的现在分词连用,构成进行时态,也可与及物动词的过去分词连用,构成被动结构。

be可以和动词不定式连用,有以下几点意义:

①表示计划或安排要发生的事或打算要做的事,不定式可用被动式,在was或were后用不定式的完成式可表示“本来打算…”;

②表示“必须”“得”等,意思接近must, have to;

③表示“应该”“宜于”等,意思接近should,有时用来征求对方的意见,不定式可用被动式;

④表示“可以”“能”等埋磨,意思接近can, may,多用于被动结构;

⑤表示“想要”等,意思接近want to, intend to;

⑥表示注定要发生的情况,常用于过去式;

⑦表示虚拟语气,用于与事实相反的条件句中。

be置于句首引起倒装句,可表示虚拟语气,这带点文学色彩,不太常用。

英语中be动词的用法

Be动词在一般过去时中的变化:

1.am 和is在一般过去时中变为was。(was not = wasn’t) 2.are在一般过去时中变为were。(were not = weren’t)

3.带有was或were的句子,其否定、疑问的变化和am,is, are一样,即否定句在was或were后加not,一般疑问句把was或were调到句首

am,is are 都属于be动词,be是他们的原型 be动词的一般现在时有局顷早三种形式,即:am, is, are。 1. 如果主语是第一人称I(我)时,be动词用am。 如:I am a student. 我是一名学生。 I am 还可缩写成I'm。如: I'm David. 我是大卫。

2. 如果主语是you (你,你们), they (他们,它们,她们)或名词复数 (两个以上的人或 物)时,be动词必须用are。 如:Are you twelve? 你是十二岁吗?

Tom and Lily are good friends. 汤姆和莉莉是桐雀好朋友。 They are at school. 他们在学校。

are与主语还可缩写。如: We are= We're, They are =They're, You are = You're。而are与 not可缩写成aren't。 如:They aren't students. 他们不是学生。但是am与not不能缩写。

3. 如果主语是单数名词、不可数名词或单数第三人称代词(he, she, it)时,be动词用is。 如:My mother is a teacher. 我的妈妈是一名老师。 He is a student. 他是一名学生。

is也可与主语缩写,如: He is = He's, My mother is = My mother's等。但是This is不可缩写。而is与not可缩写成 isn't。 如:This isn't a book. 这不是一本书。

根据以上叙述我们可以把动词的用法以口诀的形式表述出来: 我(I)是am, 你(you)是are,

剩下is留给她(she), 他(he), 它(it), 两个以上都用are。

be动词am,is,are,如何正确使用它。我用am,你用are,is用于他、她、它。以上主语是单数.

复数主语全用are。指示代词作主语,This,that用is,These,those要用are。若是变为否定句,Not系动词后面加。若变一般疑问句乎肢,句首A m,Is,Are,句末问号莫忘加。回答一般疑问句,Yes,或N o简回

be动词有哪些分别怎么用

be动词意思和用法很多,一般的意思是:是,此种用法,有多种变化形式,is,am,are,was,were,being,been,to be.另型贺外,be动词还有成为的意思。

be (be/is/are/am/was/were) [bi:] vi 现在时 I am, you are, he is, we are, you are, they are (缩略式 I'm, you're, he's, we're, you're, they're), (否定缩略式 I'm not, isn't, aren't), 过去时 I was, you were, he was, we were, you were, they were (过去时否定缩略式 wasn't, weren't), 过去分词been, 现在分词being 英语的“be”是个特殊动词;有些语言,如马来文等,并没有“be”这样的动词。 “Be”除了原形的“be”之外,还有另外七种形式:am, is, are, been, being, was, were. 在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)

编辑本段例句对照

【当主动词时,“be”在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。例如: 1. The man is a science teacher. 这个男子是一位科学教师 2. Mary's new dresses are colourful. 玛丽的新衣服色彩鲜艳 3. I have been there before. 我以前卜者派去过那里 4. My mother is watching TV in the room. 母亲现在在客厅看电视 【这四个都是陈述句,可以变成疑问句,方法简单,把主语和“be”或助动词对换位置即可: 5. Is the man a science teacher? 6. Are Mary'嫌滑s new dresses colourful? 7. Have I been there before? 8. Is mother in the kitchen now? 【当“be”要在祈使句中出现时,它必须借重助动词“do”或“don't”之助,如: 9. Don't be silly! 10. Do be obedient! 11. Don't be a fool! 【“Be”有两种缩写法,如下: 12. He's not...../He isn't.... 13. You're not...../You aren't... 【但“am not”的缩写法只有一个: 14. I'm not. 有人用“ain't”, 但这并不是标准英语。 谈过了“be”作主动词的功能,现在看看“be”作助动词时,有些什么用法: 【1.】“Be 现在分词”以组成进行式时态(Continuous Tenses),如: 15. Tony's maid is washing his new car. 16. The children are playing in the field. 17. Samuel was eating when I came in. 18. We have been living here since 1959. 【2.】“事/物人 Be 过去分词”以组成被动语态(The Passive Voice),如: 19. Her money in the drawer was stolen. 20. A number of good jobs are taken up byforeigners. 21. David studied in Taiwan but has been trained as a language lecturer in America. 22. Can all the wonderful birds be found in our Bird Park? 23. The disobedient boy was told to stand out- side the classroom. 24. Steps are being taken to reduce traffic con- gestion during peak hours. 25. Dishonest students will be immediately dealt with.
