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.
be动词的用法
例句对照
编辑本段be动词的意思
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。
编辑本段be动词的用法
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'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.】“情态动词+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.
连系动词be的用法
I． 概念
连系动词be，在刚开始学英语句子时，恐怕你首先遇到动词王国中的成员就是be。不少同学对be的说法不一，这叫be如何“是”好？连系动词be的基本意思是“是”，其实，不少场合连系动词be也充当“不是”。真可谓“是也不是”。让你先一睹be的“容貌”吧。
（1）询问年龄及回答时be不译出。
—How old are you? 你多大了？
—I'm eleven.我十一岁。
（2）询问姓名与回答时be不译成“是”。
—What's your name? 你叫什么名字？
—My name is Amy. 我叫Amy。
（3）在一些表示问候的用语及答语中be不译出。
—How are you? 你好吗？
—I'm fine. Thank you. 我很好。谢谢。
II． 用法
连系动词be是am, is, are三者的原形，一般不直接出现在句子中，而是以am, is, are的形式出现。它们各有分工，而且随着主语的人称和数的变化而变化。am最专一，始终跟着I转；are 跟you, we及表复数名词或复数意义的词连用；is的交际最广泛，is与“他、她、它”形影不离，至于名词单数，指示代词（this/that）都与is结下不解之缘。
刚开始学习英语的同学，往往对连系动词be与主语人称保持一致的问题把握不好。为此，建议你在歌谣中熟悉连系动词be的“身影”：
我用am，你用are；
is用在他、她、它；
遇到复数全用are。
一般来说，be是当系动词用的，但是当有助动词，比如can could will would shall should，后面就要加原型（和普通的动词差不多），完成事态用been，如have/has/had been
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)
我用am，你/你们/他们用are，他/她用is
过去式有was(用于我，他/她),were（用于他们/你/你们）
