be动词的?一般现在时有三种形式，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。
[思路分析]
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）
[解题过程]
（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？）
I am reading a magazine.
（我正在阅读杂志。）
例：He will be taking a walk in the park at this time tomorrow morning.
（明天早晨此时他将会正在公园散步。）
例：She has been teaching English in our school for years.
（她已在我们学校教英语许多年了。）
解说第?一例句是表达现在进?行时，第?二例句是将来进?行时，第三例句是现在完成进?行时。（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。）
例：Those keys were found in your drawer.
（那些钥匙是在你的抽屉?里找到的。）
例：It can be done much faster in this way.
（这件?工作?用这个?方法可以更加快速地做好。）
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.
从上?面例?子看，“be”这动词外貌平凡，但内涵丰厚。如果没有“be”，补?足语的桥梁断了。如果没有“be”,何来进?行式时态和被动语态？缺了这?几样重要的句式，英语还像英语吗？
动词be的本领演?示
动词be：我是系动词的总称，我叫be动词。今天我就要给?大家演?示?一下我们家族中的are，is和am的本领。下?面听听它们是怎么说的：
Are：凡是表?示多数（复数）的?人称或名词都必须跟我连?用；凡是第?二?人称you，不管是单数还是复数，也必须来找我。例如：
How are you today？你今天怎么样？
Jenny and Mary are in Canada. 詹尼和玛莉在加拿?大。
Is：虽然复数?人称、第?一?人称和第?二?人称都与我?无缘，但我总是和第三?人称单数?一起连?用。例如：
My teacher is in China. 我的?老师在中国。
Am：我永远只和第?一?人称I?一起连?用，不信你瞧：I am a teacher. 我是?老师。
动词be：谁能告诉我你们在句中表?示什么意思？
Am：我们都表?示“是”，但是当我们和介词短语或地点副词连?用时，我们通常翻译为“在”；如果和形容词或数词（表年龄）连?用，通常不翻译。例如：
I am in the classroom. 我在教室。
They are young /25. 他们年?青/25岁。
动词be：那么什么情况下不缩写呢？
Are：我只知道我们在句中不重读时要缩写。例如：
He’s a student. 他是?老师。
难道还有不缩写的时候吗？
Is：当然有，This与我is连?用不缩写：
This is a chair. 不能说This’s a chair.
Am：这是因为This的尾?音与is的尾?音相近，缩写后不容易读出来的缘故。还有，如果我们三个在句尾时，?一般不缩写，这是因为我们要重读。例如：
There it is. 它在那?里。
Here you are. 给你。
动词be：最后我再考你们三道题：
Tom and I ________ teachers.
You ________ a word (单词).
Class Two ________ on the playground (在操场上).
动词be：Tom and I是两个?人，是复数，?用are；You在这?里看作是?一个单词，所以?用is；Class Two表?面上是?一个班，但实际上是指?二班的学?生，所以?用are。好了，希望你们认真学习，不仅仅要看表?面，还要看透本质。只有这样，才能掌握更?高、更深的知识。
系动词be的?用法
张家港三兴?小学游健英
最近，五年级的?小朋友学习了系动词be的三种形式：is, am, are。在汉语?里它们都表
?示“是”的意思，?而英语?里却有这么“三个?小兄弟”，于是有的?小朋友因为不能正确区分?而愁眉不展。别急，读读下?面这个简易?口诀，再去做题，相信你回豁然开朗。
Is, am, are ，
通通译成“是”。
“我”是am, “你”是are，
is跟着“她”，“他”， “它”。
要想区分is 和are,
请你记住啦：
单数是is, 复数都是are。
如要提问是不是，
is, am, are 往句前提。
要想否定说不是，
not要往is, am, are的后?面移。
现在，?小朋友都明?白了吧！那就?自我检测?一下吧！
请?用is, am, are完成下列句?子。
1. I ____ a good student.
2. You ____not a teacher.
3. _____ he a doctor?

初中英语动词知识点：Be动词定义及用法 1. 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 2. 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。
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；名词单数、不可数名词用is，复数用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/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。 下面做个简要的讲解。 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.
be动词的过去时用法详解 划词：关闭划词收藏 编辑点评：be动词是英语时态中较为常用的动词，其用法在各种时态中可以相互转换，相当的灵活，下面小编针对be动词的一般过去时进行讲解。 3.1 be动词的过去时 3.1.1 be动词过去时的构成 肯定句：主语+ be动词的过去式（was/were）... 否定句：主语+ be动词的过去式（was/were）+ not... 疑问句：be动词的过去式（Was/Were）+ 主语...? 疑问代词/疑问副词+ was/were + 主词...? 3.1.2 be动词过去时的肯定句 句型：主语+ was/were... be动词过去时由“主语+ be动词的过去式（was/were）+ 表语”构成： I was here yesterday.昨天我在这里。 We were hungry.我们当时饿了。 The concert was last night.音乐会在昨晚举行。 The biggest problem was that we didn't have enough time.最大的问题是我们当时没有足够的时间。 There were some students on the campus.校园里有一些学生。 比较be动词的现在式和过去式： 【注意】there is/are句型的一般过去时为there was/were。
3.1.3 be动词过去时的否定句 句型：主语+ was/were + not... be动词过去时的否定句结构是在be动词过去式was/were后面加上not。否定式的was not，were not大多使用缩写形式wasn't（读作/′w znt/）和weren't（读作/w nt/）：I was not here yesterday.昨天我不在这里。 He wasn't busy the other day.前几天他不忙。 There weren't any students in the classroom.教室里一个学生也没有。 3.1.4 be动词过去时的一般疑问句 句型：Was/Were + 主语...? 回答方式：Yes，主语+ was/were... No，主语+ wasn't/weren't... be动词过去时的一般疑问句结构是将be动词过去式was/were置于主语之前（大写was/were的第一个字母），在句尾加问号；这种语序是主语和谓语倒装语序： Were you here yesterday? —Yes，I was.你昨天在这里吗? ——是，我在。 Was there any water in the river then? —Yes，there was./No，there wasn't.那时那条河里有过水吗? ——是的，有过。/不，没有。 Were your parents pleased to hear about your new job? —Yes，they were./No，they weren't.你父母听说你有了新工作后，他们高兴吗? ——是。/不是。 3.1.5 be动词过去时的特殊疑问句 句型：疑问代词（主语）/疑问限定词的名词词组（主语）+ was/were...? 疑问代词/疑问副词+ was/were + 主语...? 就主语提问时，将疑问代词或带有疑问限定词的名词词组置于be动词过去式was/were 之前（was/were的第一个字母无需大写），和一般疑问句差不多，在句尾加问号；这种语序是陈述句语序。就表语提问时，则以一个疑问代词或疑问副词开头，之后是“be动词过去式was/were + 主语”，在句尾加问号；这种语序是主语和谓语倒装语序： Who was here yesterday? —I was here yesterday.昨天谁在这里? ——昨天我在这里。（就主语提问） How many people were present at the meeting? 参加会议的有多少人? （就主语提问） How was your trip to London? 你伦敦之行过得怎样? （就表语提问）
be动词用法 be动词的一般现在时有三种形式，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.汤姆和莉莉是好朋友。 They are at school. 他们在学校。 These are books. 这些是书。 We are students . 我们是学生。 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。 She is my friend.她是我的朋友。
It is a dog. 它是一只狗。 This is a bike .这是一辆自行车。 That is a cup . 那是一个杯子。 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。 [解题过程] 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动词用法歌 be动词真伟大，生出is, am, are。 我用am，你用are，is连接他，她，它。 单数名词用is，复数名词全用are。 变疑问，往前提，句末问号莫丢弃。 变否定，更容易，be后not莫忘记。 疑问否定任你变，句首大写莫迟疑。 1 用动词be （am，are，is）填空

初一英语b e动词练习题 及答案 Written by Peter at 2021 in January
初一英语b e动词练习题及答案 1. be动词的概念： be动词是系动词的一种，是与一般动词相区别的概念。一般动词表示具体的动作。而be动词不是动作，它通常与名词、形容词或其它词类一起表示主语的性质、状态、身份、特点等等。一般动词很多，如：walk、read、stand等等，而be动词只有一个，那就是be，所以它称为be动词。be动词在不同的句子中有不同的中文意义，有时甚至不用翻译其意义。be动词有不同的形式，如：现在式有am, are, is三种，过去式有was和were 两种，过去分词只有been一种形式。 2. be动词的现在式用法： be动词的现在式有am, are, is三种，具体用哪一种，必须由主语的人称和数决定。如下表所示： 例句： I am a student. 我是一名学生。 We are all here. 我们大家都在这儿。 You are so beautiful. 你是那么漂亮。 He is my English teacher. 他是我的英语老师。 Is she nine years old 她是九岁吗 My name is Mary. 我的名字叫玛丽。 It is sunny today. 今天的天气晴朗。
Tom and his friends are in the park. 汤姆和他的朋友们都在公园里。 3. be动词的过去式用法： be动词的过去式是：was和were, 这两种形式与现在式用法没有多大区别，作谓语时用哪一种，还是由主语的人称和数决定。如下表： 例句： I was a student last year, but now I am a teacher. 去年我是一名学生，但现在我是一名老师。 We were all very happy at Tom’s birthday yesterday. 昨天在汤姆的生日会上我们大家都很开心。 You were only nine years old when I went to the university. 当我上大学时你才九岁。 He was often late for his class when he was a student. 当他是学生的时候，他老是上课迟到。 She was very sorry for that. 她为那件事感到很抱歉。 Tom and his friends were playing football when I saw them. 当我见到他们的时候，汤姆和他的朋友们正在踢足球。 4. be动词的句型如下： 肯定句：主语+be动词……
