❶ 英语中的be动词是什么意思

在英语语法中,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.另外,be动词还有成为的意思。根据句子中不同的人称、数和时态,应该选择相应的be动词。
要看语句的时态:
如果是一般过去时,就用was/were
如果是一般现在时,就用am/is/are
如果是一般将来时,就用will be
然后看主语的人称及复数形式:

一般过去时:
第一人称和第三人称的单数形式,则用was
第一人称和第二人称、第三人称的复数,则用were
一般现在时:
第一人称单数形式,用am
第三人称单数形式,用is
第一人称复数、第二人称、第三人称的复数形式,则用are
一般将来时:
will be
口诀:一般时态有关be动词的口诀
我用am,你用are,is连着他她它,单数主语用is,复数主语全用are
用法
be (be/is/are/am/was/were)
[bi:]
vi
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)

例句对照
【当做主动词时,“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:
The man is a science teacher.
这个男子是一位科学教师。
Mary's new dresses are colourful.
玛丽的新衣服色彩鲜艳。
I havebeen there before.
我以前去过那里。
My motheris in the kitchen now.
我妈妈现在在厨房里。
★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:
Is the man a science teacher?
Are Mary's new dresses colourful?
Have I been there before?
Is mother in the kitchen now?
★当“be”要在祈使句中出现时,陈述句可借助助动词“do”,否定句必须在前加上助动词“don't”,如:
Don't be silly!
Do be obedient!
Be careful!
Don'tbe a fool!
★“Be”有两种缩写法,如下:
He's not...../He isn't....
You're not...../You aren't...
★但“am + not”的缩写法只有一个:
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
【1.】“Be + 现在分词”以组成进行式时态(Continuous Tenses),如:
Tony's maidis 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.
【2.】“事/物人 +Be + 过去分词”以组成被动语态(The Passive Voice),如:
Her money in the drawer was stolen
A number of good jobs are taken up by foreigners
David studied in Taiwan but hasbeen trained as a language lecturer in America
Can all the wonderful birds be found in our Bird Park
The disobedient boywas told to stand out- side the classroom
Steps are being taken to rece traffic con- gestion ring peak hours
Dishonest students will be immediately dealt with

初中英语to和be动词的用法和翻译归纳 (英语不好归纳的详细一点)

初中英语中Be 动词的用法归纳
be是一个多功能动词,在初级英语里可见四种用法: 功能一,系动词be
be为连系动词,中心词义是"是",句型为"主+系+表"结构。be的形式常用am, is, are(现在式);was, were(过去式);will/can/may/must be(助动词/情态动词+原形);have/has/had been(助动词+过去分词)等。如: To help animals is helping people.(一般现在时) The twins were very busy yesterday.(一般过去时) It will be sunny tomorrow.(一般将来时)
She has been ill for over a week.(现在完成时) 功能二,助动词be
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 ing the new words now.
Young Tom was always asking questions and trying out new ideas. 2. be+done:构成被动语态(主语是动作的承受者,done必须是及物动词)。如:
Tea is grown in my hometown.(一般现在时的被动语态)
This building was built three years ago.(一般过去时的被动语态)
Our classroom has been cleaned and tidied already.(现在完成时的被动语态)
How could this kind of cakes be made in your home?(含情态动词的被动语态)
That is a day never to be forgotten.(动词不定式的被动语态)
3. 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.

void function(e,t){for(var n=t.getElementsByTagName("img"),a=+new Date,i=[],o=function(){this.removeEventListener&&this.removeEventListener("load",o,!1),i.push({img:this,time:+new Date})},s=0;s< n.length;s++)!function(){var e=n[s];e.addEventListener?!e.complete&&e.addEventListener("load",o,!1):e.attachEvent&&e.attachEvent("onreadystatechange",function(){"complete"==e.readyState&&o.call(e,o)})}();alog("speed.set",{fsItems:i,fs:a})}(window,document);

I didn't know if she was going to come here. 4. 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.
功能三,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?
功能四,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. Kate's birthday party will be at half past six this evening.
Jim has been in China for more than two years, but he has not yet been to Yichang.
不定式的句法功能,除了谓语外,不定式可以担当句子的任何成分。To see is to believe. 眼见为实。(作主语和表语)
To save time is to lengthen life. (不定式短语作主语)
You should continue to learn as long as you live.
要活到老学到老。(不定式短语作宾语)
She usually has a lot of meetings to attend in the evenings. 她晚上经常有很多会要开。(不定式短语作定语)
To /In order to do a good job, we must have the right tools.
要干好活工具得用对。(不定式短语作目的状语)
He got up early in order to/ so as to catch the first bus.(不定式短语作目的状语)
I didn't expect you to arrive so early.
我没想到你来得那么早。(不定式短语作宾语补足语)

❸ 英语中be动词是什么意思

be是英语动词中比较特殊的一类动词,其使用频率很高,牵涉到各种句型、时态和语态等用法,今天就跟大家分享一下be动词的各类用法。

一、系动词be

作为系动词(也叫连系动词,link verb)的be,是英语学习者接触最早的用法,而且其用法也很多。其基本含义为“是”,基本用法结构为“主语+be+表语”,也就是我们常说的主系表结构,其中的表语一般都由名词、形容词、数词或表地点、时间等的短语来充当。

系动词be有各种时态的变化,也会和情态动词连用。

(一)be的时态变化

系动词be会有一般现在时、一般过去时、一般将来时、现在完成时、过去完成时等的时态变化。如:

Heisa student.

Theywerein the park yesterday.

Itwill becloudy tomorrow.

Hehas beenill for six days.

Ithad beenthree hours before she left the hat shop.

(二)be与情态动词的连用

其用法为:情态动词+系动词be原形。如:

Itmust beLucy's book. Her name is on the cover.

Itcan bevery difficult for us to memorize too many words within such a short time.

Sheshould behere on time tomorrow.

二、助动词be

作为助动词,be没有具体含义,而是与主要动词一起构成句子的谓语动词。这种情况下,be主要用来构成进行时和被动语态。

(一)进行时态中的be

此时,be可以与主要动词的现在分词一起,构成各种进行时态。如:

Heisreading in the library now. (现在进行时)

Shewasswimming in the river this time yesterday. (过去进行时)

Theywill bearriving in Beijing tomorrow. (将来进行时)

Wehave beenlearningEnglish for ten years. (现在完成进行时)

(二)被动语态中的be

助动词be能够与主要动词的过去分词一起构成被动语态,即be done结构。如

Chineseiswidely used around the world nowadays.

The windowwasbroken by the naughty boy just now.

Your watchhasalreadybeenrepaired.

【注意】

助动词be能够构成特殊句型。如:

1、be going to do

be going to do表示“打算或将要”。如:

Heisgoing to visit us next week.

Itisgoing to rain soon.

2、be about to do

be about to do表示“刚要,即将”。与be going to do表“将要”不同的是,be about to do表示的是说完话后马上就要去做或是短期内马上就要去做。如:

The planeisabout to take off in five minutes' time.

3、be to do

be to do表示“按计划要做”。如:

One night an angel came to Mary and told her that shewasto have this special boy.

The new storeisto be opened tomorrow.

三、特殊句型中的be

(一)There be句型

与上面用法都不同的是,be可以与there一起构成there be句型,用来表示存在。考虑到There be句型较为重要,内容较多,在此不做赘述,后面再找时间跟大家单独分享。今天就先给几个常见的例句。

There isa white ruler on the desk.

There werea greatmany people in the car race last year.

(二)祈使句中的be

这种情况下,句子一般以Be开头或是Don't be开头,表示命令或建议等。如:

Bepatient! (耐心点!)

Don't beso hard on me! (不要对我们这么严厉!)

(三)虚拟语气中的be

be有时可以放在句首,引起虚拟语气。如:

Be he rich or poor, she will marry him.

Be it true or not, shewill see it herself.

此时的be引导的句子其实相当于一个让步状语从句。以上两句话就相当于:

Whether he be rich or poor, she will marry him. (无论他是否有钱,她都会嫁给她。)

Whether it be true or not, she will see it herself. (无论这是否是真的,她都会亲自去见证。)

❾ 英语be动词怎么用

be动词表示状态,它区别于实意动词,实意动词让人知道它的动作,如run 跑,sing唱,work 工作。 而be 动词不能叫人家知道你干什么,必须与后面紧跟的表语共同来说明主语的状态,情况。
如I am a boy.我是一个男孩。
He is tall.他个子高。
It is Sunday today.今天星期日。
而实意动词是这样的:
He runs every morning.他每天跑步。
You go to school.你上学,
I stand.我站着。
凡是不能表达具体动作的,一般用be动词。
我不知道你现在的英语程度,刚才介绍的是be动词的最基本用法。随着英语学习的进展,你还会遇到一些新问题。
如I am working.
这句话里既有be动词 am ,又有实意动词work, 但这个动词变成了working. 这句话是现在进行时,这个时态要求主语+be+现在分词(working叫现在分词)。这时候,be动词和实意动词同时出现在一个句子里。
还有其它两种情况也会有这种情况,不知你接触到没有。
如I am going to buy a new pen.我打算买一支赂直省?
He was having a breakfast then.那时他正在吃早饭。
有be动词的句子构成否定句时,在be动词后面加个not 就行了。

I am not ten.我不是十岁。
You are not a teacher. 你不是个老师。
I am not working.我没在工作。
He is not going to buy a new pen.他不打算买一支新钢笔。
把一个含有be 动词的句子变成一般疑问句只需把be动词放在句首,后面加上问号即可。
如 Are you a teacher?
Is he going to buy a new pen?
Is it Sunday today? Is he tall?
如果是实意动词的句子,构成否定句不能加be 动词。
如 You do not stand? 你没站着。
He does not go to school every day? 他每天不上学。
变成疑问句是
Do you stand?你站着了吗?
Does he go to school every day?他每天上学吗?

❿ 英语be动词怎么解释

be系动词,is
are
am的原型,在句子中作谓语,后面跟表语。在进行时态或被动语态句子中作为助动词使用
