一、be的用法及四种句子类型?
①
be动词的用法:
(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。
1、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:
He is a student.
They were in the park yesterday.
It will be cloudy tomorrow.
He has been ill for six days.
It had been three hours before she left the hat shop.
2、be与情态动词的连用 其用法为:情态动词+系动词be原形。如:
It must be Lucy's book. Her name is on the cover.
It can be very difficult for us to memorize too many words within such a short time.
She should be here 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。
1、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:
He is reading in the library now.(现在进行时)
She wasswimming in the river this time yesterday.(过去进行时)
They will be arriving in Beijing tomorrow.(将来进行时)
We have been learning English for ten years.(现在完成进行时)
2、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:
Chinese iswidely used around the world nowadays.
The window wasbroken by the naughty boy just now.
Your watch has already beenrepaired.
【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:
He isgoing to visit us next week. It isgoing 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 plane isabout 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 she wasto have this special boy. The new store isto be opened tomorrow.
(三)特殊句型中的be
1、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。
There be句型较为重要,内容较多,在此不做赘述,后面和大家分享,今天就先给几个常见的例句。
There is a white ruler on the desk. There were a great many people in the car race last year.
2、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 be so hard on me! (不要对我们这么严厉!)
3、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, she will 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。)

我用am,你用are,is用于他她它,单数is,复数are
二、动词be的四种句型结构?
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 copying 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.
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.
肯定句:直接放在主语后面,主语+be+其他。
否定句:be后面加not,主语+be+not+其他。
一般疑问句:be动词提到句首,Be+主语+其他。
特殊疑问句:特殊疑问词+一般疑问句。
三、be的用法和意思?
be动词的意思是:是,此种用法,有多种变化形式,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。
be动词的用法
英语的“be”是个特别动词;有些语言,如中文和马来文,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).
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.
2、 Mary's new dresses are colourful.
3、 I have been there before.
4、 Mother is in the kitchen now.
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'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、“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.
四、be的语法有哪些?
be的用法如下:
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。
