2. 熟练使用祈使句。
四、知能提升：
（一）知识讲解
I. Be 动词
1. 分类：英语中be 动词的一般现在式有三个，分别是：am,is,are .
2. 用法：am 和主语I （我）连用。is 用于he （他）, she （她）, it （它）和主语是单数的句子当中。are 用于we （我们）, you （你们）, they （他们）和主语是复数的句子中。 例：
I am a student.
He ’s a postman. She isn’t my English teacher .
Tom and I are the same age.
Where is my dress? Here it is .
Where are my shoes? Here they are.
We are both tall.
You are tall, too.
小结：be 动词用法结构图：
is Tom It She He not m I')(am I ????
?↓否 t isn')(否 a r e b o y s T h e I a n d T o m Y o u T h e y We ????
?????
（否）aren’t
be 动词用法歌诀：
Be 动词，兄弟仨，am, is, 还有are 。
我（I）用am ，你（you）用are ，is用于他（he），她（she），它（it）。
单数名词用is，复数名词都用are 。

II.祈使句
<一>定义：祈使句表示请求、命令、建议等。谓语动词一律用原形。句子中通常不用主语，句末用惊叹号或句号，用降调来读。
<二>分类：肯定的祈使句和否定的祈使句.
1. 肯定的祈使句
a. 句型：动词原形～.（省略主语）
Stand up.起立。Be quiet，please.请安静。
比较陈述句：You sit down.你坐下来。祈使句：Sit down.坐下。（省略主语you）
注意：有时，为了加强语气，可在动词之前加do。
Do sit down.务必请坐。Do study hard.一定要努力学习。
b. 用客气的语气表示祈使句时，可在句首或句尾加上please，但如果在句尾加please，
那在please之前一定要加一个逗号“，”。
Come this way，please.请这边走。
注意：祈使句中如果有呼唤语，一定要用逗号“，”隔开，呼唤语可出现在句首或句尾。
Li Ming，come here.李明，过来。Come here，Li Ming.过来，李明。
c. 含有第一、第三人称主语的祈使句
Let's say good-bye here.我们在此道别吧。Don't let him do that again.别让他再那么做了。
句型：Let+第一人称（me，us）～.
Let+第三人称代词（宾格：him，her，it，them）或名词～.
Let's go at once.咱们马上动身吧。
Let me try again.让我再试试。
Let Tom go there himself.让汤姆自己去那儿。
注意：
Let's包括听话者，Let us不包括听话者。用于反意疑问句时最明显。
Let's go，shall we？咱们去吧，怎么样？
Let us help you，will you？让我们帮帮你，好吗？
2. 否定的祈使句
句型a：Don't +动词原形～
Don't swim in the river.别在河里游泳。
Don't be late.别迟到。
Please don't be noisy.请不要大声喧哗。
注意:
表示禁止时，尤其是标语等也可用“No+名词／动名词”的形式来表示。
No smoking!禁止吸烟！
No parking!禁止停车！
No litter!不准乱扔杂物！
句型b：Let's（us，me）+not +动词原形～.
Don't let +第三人称代词的宾格或名词+动词原形.
Let's not say anything about it.
对于这件事，咱们什么也不要说。
Don't let them play with fire.
别让他们玩火。
【易错点】
1. be 动词的缩写形式：
I am =I'm he is =he's it is = it's she is = she's you are=you're we are = we're
they are = they're is not =isn't are not = aren't
*am not 没有缩写形式.I'm不能用在句末。*
2. 祈使句的回答：
回答祈使句时，应该说“OK./ All right./ Great./Good idea.”(好的，好吧，好极了) 决不能用“That's OK./ That's all right .”(没关系)
如：—Let's fly it .—Great !
—Show me your ruler .—All right .

(完整)初中英语be动词用法
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

She is 16 years old. My father is at home. The students are playing games. My teacher was ill yesterday. There is a picture on the wall. There are two books on the table. ★ be 动词用法歌： 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。 ★ be 动词作谓语，它后面一般跟名词、形容词或介词短语。她个子很高。 她在教室里。她是一个高个子的女孩。 2、助动词的用法。 英语句子按正常语序是“什么人或事物” + “做什么”，即，我们常说的“主语+ 谓语+ 其他” 。 ①主语为I 或复数名词、代词时：肯定句：I / We / They / The students
＋动词原形＋其他＋。 We watch TV every night. 变否定：主语＋don't ＋动词原形＋其他＋。 We don't watch TV every night. 一般疑问句Do + 主语+ 动词原形+ 其他+ ？ Do you watch TV every night?

Yes, he does. / No, he doesn 't. 特殊疑问句：疑问词+ does + 主语+ 动词原形+ 其他+ ？ How often does he watch TV? ★主语为单数或不可数名词，谓语要用单数第三人称，反过来，看见动词用了单数第三人称，可以推知主语是单数或不可数名词。 ( )1. How __ ______ your dad help at home? A. do B. does C. is ( )2. ______ goes bad easily in summer. A. Milk B Apples C. Cakes ③过去时的句式（当句子时态为过去时时，动词用过去式，不受主语单复数的影响） 肯定句：主语+ 过去式+ 其他+ 。 He / We got up early every morning last year. 否定句：主语+ didn't + 动词原形+ 其他+ 。 He / We didn't get up early every morning last year. 一般疑问句：Did + 主语+ 动词原形+ 其他+ ？ Did he / you get up early every morning last year?

Be动词和助动词用法辨析
Be动词和助动词用法区别其实be动词也是助动词（auxiliary verbs）。 英语动词大致可分为三种：助动词（auxiliary verbs），情态动词（modal verbs），实意动词（full verbs）。 助动词（auxiliary verbs）：do，be，have。没有实意，“帮助”别的动词，表示时态，否定和提问。情态动词（modal verbs）：can，must，may。也是“帮助”别的动词，但是有自己的实意。实意动词（full verbs）：play，run，think。其他有实意的动词。 be动词可用作助动词（auxiliary verbs）：1，be+Ving：所有的进行时态，如：2，be+过去分词：被动式。 be动词也可用做实意动词（full verbs）：be[bi]v.有；在；是。 你这样想，一个句子里要有动词吧。再看看它们的名字，“be 动词”和“助动词”， 先说“be动词”，（1）这名字里有动词，说明他是动词，句子里有他就不会有别的动词（除非这些动词以别的形式出现，这是后话）了，（2）“am,is,are,was,were”叫be动词，是因为他们是be的不同形式 再说“助动词”，（1）一定要注意“助”，是帮助的意思，说明他不是动词，只是起到了辅助的作用，所以，他们就一定要与动词同时出现。[记住啊，他们离不开动词，但是动词没有他们也是可以的]
（2）did,do,does只是do的不同形式，根据你所需要的时态来选择（1）用于肯定句，否定句和疑问句 am：第一人称单数（即只与I连用），用于现在时（一般现在，现在进行，只要那时态中是现在的就行）eg:①I am a girl.一般现在时②I am eating an apple.现在进行时 ③I am going to do my homework.[be going to表将来，将来中只有这一种] is：第三人称单数，用于现在时（一般现在，现在进行，只要那时态中是现在的就行）(it就不举例了)eg:①She/He is a girl/boy.一般现在时②He/She is eating an apple.现在进行时③He/She is going to do his homework.[be going to表将来，将来中只有这一种] are：第二人称单数，所有人称复数，用于现在时（一般现在，现在进行，只要那时态中是现在的就行）eg:①You are a girl. We/You(你们)/They are girls.一般现在时②You are eating an apple.We/You(你们)/They are eating apples.现在进行时③We/You(你们)/They are going to do our/your/their homework.[be going to表将来，将来中只有这一种] was：第一人称单数，第三人称单数，用于过去时（一般过去，

Be 动词专项练习 be动词的一般现在时有三种形式，即：am, is, are（翻译为“是”） 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。am 与not 不能缩写。如：I am not a bad boy. 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。 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。 4. 句中含有be动词的陈述句变一般疑问句。 把be动词提到句首，be动词要变大写。注意第一人称变第二人称。回答时用yes或no表示，结构：Yes, 主语+be动词，No，主语+be动词+not。 如：It is a book. 变为：Is it a book? 5. 句中含有be动词的肯定陈述句变否定句。 先找肯定陈述句中的be动词，在be动词后加not. 如：It is a book. 变为: It is not a book. 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)用am，你(you)用are， is连着他(he)，她(she)，它(it)； 单数名词用is，复数名词全用are。
be动词和助动词句式
1.be动词（am/is/are） 主语be动词（原形）be动词（过去式） I am was He/she/it is was We/you/they are were 口诀：我用am, 你用are，is用在他她它，所有复数全用are ①肯定和否定句 I am (not) from London. He is(not) a teacher. She is(not) in the dining room. My hair is(not) long. Her eyes are(not) small. ②一般疑问句 Am I a Chinese?——Yes, you are. /No, you aren’t. Is the cat fat? ——Yes, it is. /No, it isn’t. Are they American?——Yes, they are. /No, they aren’t. 表示疑问，一般回答只有两种可能Yes或No，句中没有疑问词。 如何将一个肯定的陈述句改为否定句： 1、看句中有无be动词，如有，把be动词提到句首即可。 2、看句中有无情态动词，如有，把情态动词提到句首即可。 3、如上述二者都没有，就应把助动提到句首。分四个步骤： （1）肯定陈述句中本来是没有助动词的，要加上去，位置在主语（某人/某物）后，动词前。 （2）确定助动词用do、does还是did，根据句中动词，动词是原形的助动词就用do，动词是第三人称单数的助动词就用does，动词用过去式的助动词就有did。
（3）把助动词后提到句首。 （4）原句中动词假如发生变化就要恢复成原形。 有some的要考虑是否要用any 2.助动词（do/does/did） 主语助动词（原形）助动词（过去式）否定形式I/We/you/they do did don’t/didn’t He/she/it does did doesn’t/didn’t ①.Do+非第三人称单数＋动词原形…? do/don't you/they have...?—Yes, I do/No, I don’t. ②.Does+第三人称单数＋动词原形…? does/doesn't he/she have...?—Yes, he does./No, he doesn’t. ③Did+所有主格＋动词原形…? did/didn't you/he/she/they go to school?—Yes, i did./No, I didn’t. 3.特殊疑问句 表示疑问，有疑问词开头，回答有很多种可能。常用疑问词：What、Who、When、Which、Why、Whose、How ※What do you/they/we…+动词原形？I/They/We+动词原形… What does he/she/it…He/She/It +(动词＋S)….

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……
