be动词怎么用

be动词的用法如下:

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,am, is, are,was,were,being,been.另外,be动词还有成为的意思。根据句子中不同的人称、数和时间,型态,应该选择相应的be动词。

be作助动词用的形式如下:

①am, is, are, was, were

②助动词+be:shall be, will be, can be, etc.

③have/has/had + been(完成时)

④am, is, …being(进行时)

(1)表达进行时态

句型 be + V-ing…(进行时态)

例:What are you reading?

(你正在阅读什么?)

(2)表达被动语态

句型 be +p.p.(被动语态)

例:English is spoken in both Canada and the United States.

(加拿大和美国都讲英语。)

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:The man is a science teacher.

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:Don't be silly!

“Be”有两种缩写法,如下:He's not...../He isn't....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:

Be + 现在分词”以组成进行式时态(Continuous Tenses),如:Tony's maid is washing his new car.

“Be + 过去分词”以组成被动语态(The Passive Voice),如:Her money in the drawer was stolen.

Be动词的用法

be动词用法口诀:

be动词真伟大,生出is,am,are。

表否定很简单,not加在be后边,

若要变为疑问句,be应移到主语前。

还有一点要注意,句末问号别忘记。

be动词用法:

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。

例句:

To help animals is helping people.

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。

例句:

The girls is reading and copying the new words now.

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)。

例句:

Tea is grown in my hometown.

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。

例句:

4、be+to do,表示"按计划安排将要做某事"。

三、there be句型

四、实义动词be

英语be动词的用法

be与介词或副词连用,可以表示“位于,在(某处)”“(在某时或某地)发生”“留在(某地);逗留”“出席;到场”等。be用于完成时时,可接介词或副词表示“前往;造访”等。

be和from连用可表示“来自;是(某地的)人”。 be动词有三种不同的形式,现在式有am、is、are,过去式有was、were,过去分词有been。

例句:用作动词 (v.)

It is necessary that he be sent there at once.

有必要马上派他到那里去。

There will be rain in all parts of the country.

全国各地将有雨。

be系动词的用法:

1、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。

2、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,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。

3、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。

4、be作系动词可用于There is/are句型,意思是“有;存在”。

5、be还可与名词、代词、形容词、副词、介词短语、动词的现在分词及过去分词、动词不定式或名词性从句连用,以提供名称或信息。

be还可用于It is/was句型,用于描述情况或表达想法,也可用于表达时间等。

be动词的用法有哪些

当主语是第一人称(I)时,be动词用am。

当主语是第二人称(You,They等)时,be动词用are。

当主语是第三人称(She,He,It等)时,be动词用is。

它们的过去式分别为:

am的过去式是was;is的过去式是was;are的过去式是were

例句:

1、I am already as tall as she is

我已经和她一样高了。

2、We are cognizant of the problem.

我们意识到了这个问题。

3、This man is an animal, a beast

这人是个畜生,是个野兽。

4、I knew right away she was dead

我马上就知道她死了。

5、We were all badly bitten by mosquitoes.

我们都被蚊子咬惨了

扩展资料:

意思

“Be”除了原形的“be”之外,还有另外七种形式:am, is, are, been, being, was, were.

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:

第一人称单数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

第二人称单数也用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、第二人称复数、第三人称的复数形式,则用are

第二人称单数也用are

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。

一般将来时:

will be

will在一般情况下相当于be going to,表示将要做什么.

有细微差别will更口语化点,be going to表示有可能马上要着手去做的事情.

will后面加动词原型,am /is /are的原型是be,所以will be就是表示将要成为,将要是……

例如:i will be a mother.我将要成为母亲了.

还有一种情况是will后面要跟被动语态了,也会出现will be 的形式.

例如:she will be fired.她将被炒鱿鱼了.

will be 和will区别

前面是将要成为,将要是什么,后面加动词原形。

后者是将要做什么,后面跟形容词。

will be doing sth和will do sth区别

前面是将来进行时,将来某个时刻正在做某事

后面就是一般将来时 表示将来打算做某事
