初中语法：be动词的用法[5篇]

第一篇：初中语法：be动词的用法

★Be动词的形式和搭配：

1.be 动词am, is ,are 的原行，be动词在句中运用时，在一般现在时句中，需根据句子主语的不同，选择用am, is, are，而be动词一般不直接用在句中。

am, is, are 在句中的用法（我用am，你用are , is用于他、她、它，复数全部都用are.）：

(1)am 是，“am”要与第一人称代词“I”连用，即，只有句子主语为“I”时，“I”与“am”缩写形式为I’m.如：I am a student.I am Michell.(2)is 是，“is”用在句子主语为单数时，或不可数名词时使用。其缩写形式为 He’s , She’s, It’s.如：He is twelve.She is my sister.It is a clock.(3)are 是，“are”用在句子的主语为you，表示有两个或两个以上数目的复数名词，代词以及“and”连接的两者或多者一起构成的主语时。其缩写形式为 you’re.（习惯上）

如：You are a student.Tom and I are good friends.注意：am , is , are 与前面的代词或名词的缩写形式只用在句中，且在它们之后还有其他词时；如果无其他单词时，则不应将它缩写。

如:---Are you Michell?

---Yes, I am.(此时的I 与am 不能缩写)2.Be 动词的否定形式的变化：

否定句：只需要在be（am, is, are）后面加上not 就行。但要注意缩写形式。

如：I am not a student.You aren’t a teacher.He isn’t a good man.There isn’t a pen.There aren’t some bags in the shop.(am not , is not=isn’t

are not =aren’t)总结：am 一般与not 一起时不缩写；is 与not 缩写为isn’t，are not 缩写为aren’t , isn’t 和aren’t 在句中运用时，不管后面有无其他单词都可以用，不用分开写。

如：a.----Is that an English book?

----No, it isn’t.b.We aren’t teachers.We’re students.3.一般疑问句：只需要把be动词提到句子开头就行，第一个字母要大写。

Are you a good student? Yes, I am.Is he reading books? No, he isn’t.Is there a new school in your hometown(家乡)？Yes, there is.Are there your parents and your grandparents in your family? Yes, there are.★be动词的四种功能用法：

1.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)

2.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：

a.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.b.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)

c.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.d.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.3.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?

4.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.

第二篇：初中动词不定式用法讲解

初中动词不定式用法讲解

动词不定式是动词的一种非谓语形式，又叫非谓语动词，它没有人称和数的变化，在句子中不能做谓语；它由“to+动词原形”构成，这里的to是动词不定式符号，本身没有词义，其否定形式常在to前加not；由于它仍保持动词的特点，可以有自己的宾语和状语，还可以带疑问词和由for引出其逻辑主语等形成动词不定式短语；不定式或不定式短语具有名词、形容词和副词的特征，在句子中可作主语、表语、宾语、宾语补足语、定语和状语等句子成分。为使同学们更好地掌握其用法，现总结如下：

一、动词不定式作主语

动词不定式作主语时，为避免句子的头重脚轻，常用it作为形式主语，而真正的主语动词不定式后置。如要说明动作的执行者，可在不定式前加for引导的短语；但如果表语是nice, kind, clever等描述动作执行者的性格、品质的形容词时，则应在不定式前加of引导的短语。

常用句型: 1，It +be+adj./n.+(for/of sb.)to do sth.（用of还是for决定于前面的adj, adj若是指sb.的特性，就用of，adj若是指sth的特性就用for）

例句：It’s so nice of you to help me with my homework.你真是太好了，帮助我完成作业。

It’s very difficult for me to do the math homework.数学作业对于我来讲太难了。

2，It takes sb.some time to do sth.例句：It takes my mother all day to do the housework.做家务花了我妈妈一整天的时间。

二、动词不定式作宾语

一些动词，如want, decide, hope, ask, offer, agree, choose, learn, plan, need, teach,prepare等，常接动词不定式作宾语（如want/decide to do sth.等）。当动词不定式作宾语时，如果后接宾语补足语，常用it作形式宾语，而把真正的宾语放在宾语补足语之后。注意:有些动词后面可接不定式作宾语，也可接动名词作宾语,所表达的意义也不同。如：

（1）stop to do sth.停止正在做的事，去做另一件事；

stop doing sth..停止正在做的事

（2）go on to do sth.做完一件事后，继续做另一件事；

go on doing sth.继续做同一件事

（3）remember/forget to do sth.记住／忘记去做某事；（未做）

remember/forget doing sth.记得／忘记做过某事（已做）

三、动词不定式作定语

动词不定式作后置定语时，与被修饰的名词逻辑上有动宾关系。如果动词不定式是不及物动词时，则要带上与之搭配的介词，构成及物动词短语。

如： have/has ＋某事＋to do

eg: I have so many homework to do.我有许多作业要做。

enough＋名词＋to do

eg: It’s difficult enough to do my math homework.数学作业太难了。

“It’s time to do sth.”

eg: It’s time to go home.是时候回家了。

四、动词不定式作宾语补足语

有些动词，如tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语，构成tell/ask/want /call/invite sb.to do sth.结构。应注意动词不定式作使役动词和感官动词的宾语补足语时应省去to，在被动语态中应加上to。这些动词可归纳为“一感(feel)，二听(listen to, hear)，三让(let, make, have,，四看(look at, see, watch, notice)，半帮助(help)(即在动词help后面作宾语补足语时，to可有可无)”。另有口诀帮助记忆：“感使动词真奇怪，to在句中像妖怪，主动句中to离开，被动句中to回来。”(let不用于被动语态)

五、动词不定式作状语

动词不定式作状语主要用来修饰动词，表示目的，结果或原因。为了强调目的，有时可以把动词不定式放在句首，或在不定式前加in order或so as。常用结构有too + adj./adv.+ to do sth.等。

例句：I go to bed early in order to get up early in the next day.我那么早睡觉就是为了第二天能早起。

My little brother is too young to go to school.我的弟弟太小而不能上学。

六、固定句式中动词不定式的用法

在固定句式中对不定式的考察常见的有：

had better(not)do sth.最好做（不做）某事。

Would you like to do sth.?你想要做（不做）某事吗？

Why not do sth.?为什么不做某事？

Would you please(not)do sth.?请您可以做（不做）某事么？

七，根据以上六点，中英互译下列句子Homework（全对奖励100积分）1，你很聪明答对这个问题（clever）2, In fact, to learn English well is easy for you.___________________________________________________________

3, 他总是那么早回家看电视(watch)

He always _____________ early _____________TV.4, 让他们独自走进教室。(walk)

Let them ______________ the classroom alone.5, 你最好在九点前完成作业。(finish)

You’d better _______________before 9:00 pm.6, 为什么不购物呢？(shopping)

7, Mary上周末忘记了做家务。(forget)

Mary _______________________________________ last weekend.8, 上个暑假，三位青少年主动提出做一些志愿者工作。(offer)

Three teenagers ___________________________ some voluntary work last summer holiday.

第三篇：动词惯用法

动词惯用法

使用动词时，要遵循它们特定的句型，不能随心所欲，我们这里仅讨论测试中最常见的几种句型。1．动词+不定式

误：He managed getting that book． 正：to get 有些动词只能用动词不定式作宾语，而不能用动名词，常见的这类词有：afford，agree，arrange，ask，attempt，appear，apply，beg，bother，challenge，choose，claim，command，care，deign，dare，decide，decline，demand，desire，determine，expect，essay，endeavour，fail，guaran-tee，get（对„逐渐），hope，help，hesitate，incline，intend，know，long（渴望），learn，mean，manage，offer，plan，pretend，promise，prepare，pledge，proceed，profess（声称），presume（竟敢），refuse，resolve，seek，swear，strive，scheme，seem，threaten，trouble，tend，undertake，volunteer，venture，vow，want，wish等。

a．He volunteered to get some information．

b．Allen applied to be transferred to another department．

know后的不定式必须是带连接副词或连接代词的，如 how to，what to，who to，但不能接why to。

a．He knows how to drive a bus． b．I don't know why we should do it． 2．动词+动名词

误：I advise to wait till 9． 正：waiting 英语中有些动词或动词词组只能用动名词作宾语，而不能用不定式，常见的有：admit，advise，acknowledge，advocate，anticipate，avoid，adore，appreciate，bar，cannot help，can't resist（禁不住），can't stand，complete，confirm，consider，contemplate，confess，defer，delay，deny，detect，detest，discourage，discontinue，dislike，doubt，enjoy，envisage，escape，evade，excuse，facilite，fancy，favour，feel like，finish，forbid，forgive，give up，grudge，hinder，hold off，involve，imagine，incur，keep（on），leave off，loathe，look like，mind，miss，mention，necessitate，prohibit，put off，postpone，practise，permit，prevent，quit，pardon，recall，recollect，remain，report，require，resent，recommand，resist，resume，risk，relish，shirk，stop，suggest，shun，save，urge，visualise等。

a．Who suggest doing it this way？ b．The old worker has left off working． c．Nor do we doubt being able to finish the work on time． 3．动词+不定式/动名词

英语中有些动词既可接不定式，也可接动名词。

（1）两种结构意义差别不大。a．He declined to go there． b．He declined going there． 有些动词在接动名词或不定式时，意义差别不是很大，常见的这类动词有：begin，bear，cease，continue，commence，decline，delay，dread，deserve，endure，hate，intend，loathe，like，love，neglect，omit，propose，prefer，purpose，start，scorn等。

a．Don't neglect to lock/locking the door，when you leave． b．He omitted to read/reading the second page．

①如果start，begin，commence，cease等表示有意识地开始或停止的事情，多接动名词，否则多接不定式。

②如果like，love，hate，loathe表示一般倾向，后面多接动名词。如果指某一具体行为，则其后接不定式更多一些。如果love和like前有would或should，则其后只可接不定式。

误：I'd like hearing others'views． 正：to hear ③要注意prefer后接动名词和不定式时的搭配。

a．They prefer walking to taking a bus． b．They prefer to walk rather than take a bus． ④decline，delay，dread后接动名词更常见一些。另外，bear意为“合适”时，其后只可接动名词。

误：His language won't bear to be repeated．

正：bear repeating（2）两种结构意义不一样。

英语中有些动词可接动名词，也可接不定式，但两种结构的意义不一样。常用的这类动词有：mean，try，regret，stop，forget，remem-ber，need，wait等等。①mean a．I have meant to leave on Monday． 我打算周一离开。

b．Missing the train means waiting an hour．

赶不上那辆火车就意味着要等一小时。mean to do sth．意为“打算做„„”；mean doing sth．意为“意味着”。②try a．You must try to improve your work． 你应努力改进工作。

b．Why not try doing the experiment in some other way？

为什么不试用别的方法做这实验？ try to do sth．意为“设法做、努力做”，try doing sth．意为“试着„”。③regret a．I regret to say that we can't stay here any longer．

很抱歉我们不能再在这儿呆了。b．I regret making/having made such a mistake．

我后悔犯了这样一个粗心的错误。regret to do sth．意为“对„感到抱歉（事情没有发生）”；regret do-ing sth．意为“对„感到后悔（事情已经发生）”。④stop a．When I arrived，he stopped to talk with me．

当我到达时，他停下（手中的活）和我说话。

b．Stop talking！it's time for class．别说话，该上课了。

stop to do sth．意为“停下来（指别的事），开始做某事”； stop doing sth．意为“停止做某事。⑤forget a．Don't forget to bring your notebook next time．

下次别忘了带笔记本。b．I will never forget finding the rare old coin in my garden．

我永远也不会忘记我曾在花园发现过一枚希罕的古钱币。

forget to do sth．意为“忘记做某事（事情还没有发生）”；I forget doing sth．意为“忘记做某事这一情况（指做的事已发生）”。⑥remember a．Please remember to post my leter．请记住给我发信。

b．I remember seeing/having seen him somewhere．

我记得曾经看见过他。

remember to do sth．意为“记得做某事（事情还没有发生）”； re-member doing sth．意为“记得做过某事（事情已经发生）”。⑦need a．I need to get away and rest up a little．

我需要离开这儿，好好休息一下。b．The floor needs mopping/to be mopped．地板需要擦。

need to do sth．意为“必须做某事”； need doing sth．意为“需要”。⑧want a．I don't want to go there．我不想去那里。

b．Your English wants brushing up/to be brushed up．

你的英语需要复习一下。

want to do sth．意为“想做什么”； want doing sth．意为“需要做什么”。⑨go on doing，go on to do a．How long do you intend to go on paying those blooky records？

b．He welcomd the new stdents and then went on to explain the col-lege regulations．

c．For half an hour I went on reading Lesson Six．

d．At half past three I went on to read Lesson Six．

go on to do sth．表示“做完了某事，继续做另一件事”； go on doing sth．意为“某事还没有做完，继续做该事”。go on to read Lesson Ten 即表示已续读完了第九节课（或别的动作），进而读第十课；而 go on reading Lesson Ten即表示第十课还没有读完，要继续读。一般go on to do sth．结构经常指一个时刻的动作，而 go on doing sth．结构常指一段时间的动作。go on with sth．短语，既可指一时刻的动作，也可指一段时间内的动作。a．After a little pause，he went on with his speech．

b．He went on with his speech for half an hour．

⑩begin，start，cease，a．After he had collected the material，he began writing．

b．After a week，he began to enjoy his study．

c．The buses ceased runing． d．He ceased to breathe．

在动词begin，start，cease之后，用动名词表示有意识的动作，用不定式则表示无意识的无法控制的动作。上述三个动词如果用understand，realize等动词作宾语时，不能用动名词形式，只能用不定式。我们只能说：He began to realize he had made a mistake．(11)hear，see，feel等感官动词 a．I saw him working in the garden yesterday．

我看见他昨天在花园里干活。

b．I saw him to work in the garden yesterday．

我见他昨天在花园里干过活

在感官动词see，hear，feel，watch，notice等之后，既可用动名词作宾语，也可用不定式作宾语，用动名词作宾语时我们的注意力是集中到动作进行的过程之中的，强调过程，而用不定式则把我们的注意力集中到动作完成的事实。

a．We heard the girl singing in the hall．

b．We heard the girl to sing in the garden． a）stop后接不定式作目的状语，不是宾语，另外halt和pause后接的不定式都是状语，其后不可接动名词，因为它们是不及物动词。如

a．She halted to speak to him．她停下来（以便）和他说话。

b．He paused to have a rest．他停下来（以便）休息一下。

b）人作主语时，want和need后面常接主动的不定式，很少用动名词。物作主语时，其后既可接动名词，也可接不定式。c）在动词need，want，require，deserve，bear，stand等之后，常用动名词的主动形式表示被动意义，相当于不定式的被动结构。

a．His coat needs cleaning/to be cleaned．

b．His house wants painiting/to be painted． c．The old woman requires looking after/to be looked after．

d）在形容词afraid，certain，sure，sorry等之后，既可接动名词也可接不定式，两者含义不相同。

a．We are never afraid to do such things．

我们从不怕做这样的事情。

b．We are afraid of being late．我们担心（恐怕）迟到。

c．We are certain to be victorious．我们一定会胜利。4．动词+双宾语

（1）有些动词接双宾语，其间接宾语多数都可换为由介词to引起的短语，意思上没有什么差别，常见的有：allow，accord，award，assign，bring，deny，ensure，forbid，give，grant，hand，lend，leave，offer，owe，promise，pass，provide，quote，return，refuse，recommend，render，show，surrender，throw，teach，wish等。a．The government granted him a loan． The government granted a loan to him． b．They award John the first prize． They award the first prize to John． ask的间接宾语不可换为由to引起的短语，必须换为由of引起的短语。另外，write，send，tell，pay，read等的间接宾语也可换为由for引起的短语，但它同由to引起的短语意思不同。

a．I'd like to ask you a favour． b．I'd like to ask a favour of you． c．I wrote a letter to him．我给他写了封信。

d．I wrote a letter for him．我代他写了封信。（2）有些动词接双宾语，其间接宾语可换为由for引起的短语，意思不变，常见的这类动词有：build，buy，cook，choose，draw，do（给予），fetch，fix，find，fill，set，make，order（定购），paint，prepare，spare，save，get，sing，pardon等。a．She cooked her husband a delicious meal．

She cooked a delicious meal for her husband．

b．Please do me a favour． Please do a tovour for me． c．Let me fix you a drink． Let me fix a drink for you． d．Please fill me a glass of beer． Please fill a glass of beer for me． 5．动词+宾语 英语中有些动词只可接一个宾语。误：He informed her his new address． 正：in formed her of 英语中有些动词常因其中文含义而被误用，要注意其后介词 1）acquaint 误：The teacher did much to acquaint us the problem．

正：acquaint us with the problem acquaint是及物动词，意为“使认识、使了解、通知”。acquaintoneself with/of（开始知道），acquaint sb．with/of/that„（把„通知某人），get acquainted with（开始认识某人、开始了解某事），make sb．acquainted with（把„告知某人、使某人认识„）。

a．I acquaint myself with the fact． b．He acquainted me with the meeting． c．He acquainted me that the meeting was put off．（2）convince 误：We failed to convince him his mistake．

现在进行时的基本用法：

a.表示现在(指说话人说话时)正在发生的事情。

【No.1】现在进行时的构成

现在进行时由”be+v-ing"构成。be应为助动词，初学者最容易漏掉，它应与主语的人称和数保持一致。

【No.2】现在进行时的应用

在实际运用时，现在进行时常用以下几种情况：

(1)当句子中有now时，常表示动作正在进行，这时要用现在进行时。如：

They are playing basketball now.现在他们正在打篮球。

(2)以look, listen开头的句子，提示我们动作正进行，这时要用现在进行时。如：

Listen！She is singing an English song.听，她正在唱英语歌。

(3)表示当前一段时间或现阶段正在进行的动作，且此时有this week, these days等时间状语，这时常用现在进行时。如：

We are making model planes these days.这些天我们在做飞机模型。

(4)描述图片中的人物的动作，也为了表达更生动。此时也常用现在进行时。如：

Look at the picture.The children are flying kites in the park.看这幅图，那些孩子正在公园放风筝。

【No.3】现在进行时的变化

肯定句式：主语+be(am, is, are)+现在分词+其它.否定句式：主语+be(am, is, are)+not +现在分词+其它.一般疑问句：Be(am, is, are)+主语+现在分词+其它？

特殊疑问句：疑问词+be(am, is, are)+主语+现在分词+其它？

对现在进行时的特殊疑问句的回答，它不可以用Yes或No直接作答，要根据实际情况回答。

c.表示渐变的动词有：get, grow, become, turn, run, go, begin等。

The leaves are turning red.It's getting warmer and warmer.d.与always, constantly, forever 等词连用，表示反复发生的动作或持续存在的状态，往往带有说话人的主观色彩。

You are always changing your mind.典型例题

My dictionary ___, I have looked for it everywhere but still___ it.A.has lost, don't find B.is missing, don't find C.has lost, haven't found D.is missing, haven't found.答案D.前句是一个仍在持续的状态，应用进行时，由于没有找到，其影响仍然存在，应用完成时，瞬间动词用于否定式时可用于完成时。

e:现在进行时有时可以用来表示赞叹或厌烦的感情.例如:

He is always causing trouble.他总是惹麻烦.=====================================

The Present Continuous Tense 现在进行时

现在进行时最容易出现错误的地方在动词的现在分词形式，我们在复习的时候要特别注意不规则动词的变化形式。

例如：

taking，taking是take的ing形式,以e结尾要去e加ing;

swimming，beginning，putting,要双写最后一个字母,之后加ing;

buying,playing,teaching,等大部分单词直接加ing.有一些特殊变化(或者说以Ie为结尾的重读闭音节的动词)的现在分词〔有3个〕,:lying—lie, dying ―die tying―tie 这些以ie结尾要去e再把I变y再加ing．

1.The Present Continuous Tense 现在进行时

2.现在进行时最容易出现错误的地方在动词的现在分词形式，我们在复习的时候要特别注意不规则动词的变化形式。

3.例如：

4.swimming，beginning，putting，taking，buying。

has和have的用法

has和have都表示有，但用法不同。

has用在第三人称单数形式（能转换成it的人称形式）中；have用在第一人称和第二人称中；如果一个句子中有does(或did)的话，has变为have，does就相当于一个还原器。

例句：

has：He has a bag.他有一个书包。

have：I have a pen.我有一知钢笔。

Do you have a book?你有一本书吗？

关于does的:Does he have a notebook?他有一个笔记本吗？

She doesn't have a computer.她没有一个电脑。
