从句作主语时谓语动词单复数怎么定?
提问时间： 08:23:37提问者：
1.主语从句多表示单一概念,因此主句谓语动词多用单数.如: 　　When and where we'll go isn't decided. 　　2.what引导的主语从句,根据表达含义的不同确定主句谓语动词的单复数.如: 　　What we need are books/is water.

京公安备110-1081940所有动词都是谓语吗
谓语动词指在句子中充当谓语的动词,有行为动词,系动词,情态动词和助动词等几种,其中行为动词又包括及物动词和不及物动词.谓语动词是与非谓语动词相对应的概念．两者都是动词,但是前者是作谓语成分,后者不能作谓语成分．而谓语成分就是用来说明主语的动作或状态的,一般由动词或短语动词承担．非谓语动词　　在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词.非谓语动词分为三种形式:不定式,动名词,和分词(分词包括现在分词和过去分词).

不是的：）但是谓语里都有一个动词，无论是be动词，还是实义动词。例如：I am a teacher 这里的am就是be动词（这里be动词可以理解为是一个特殊的谓语动词），另外You can learn well .这里的can learn 在句子中的成分是谓语。
另外，动词有不定式和动名词，to do 这个不定式可以主语，宾语，表语，定语，状语和补足语，例如I have a lot...

other schools.表语2 We saw some teachers sitting there.宾语补足语3 We need to be active in class.宾语谓语宾语主语定语连系动词划分句子成分非谓语动词大都可在句中作主语、宾语、宾语补足语、表语、定语、状语等.4.To see you is glad.=It’s glad to see you.5.I want to see you.6.I want him to see you.7.My hope is to see you.8.He is the man to see you.9.I’m glad to see you.10.I went to see you.11.He went so early as to see you（作主语）(作宾语）（作宾补）(作表语）（作定语）（作原因状语）（作目的状语）（作结果状语）12.Swimming is his favourite sport.13.He enjoys swimming.14.I found him swimming in the river.15.His favourite sport is swimming.16.He is the man swimming in the river just now.17.

否定式：not to do sth.被动式：to be done
完成式：to have done二. 动词不定式的句法作用法动词不定式有副词，形容词和名词的特征，因此在句中可作主语、宾语、宾语补足语、表语定语、状语等成份。动词不定式To do that sort of thing is foolish。I want to see you this eveningAll you have to do is to finish it quickly.We found a house to live in.She came here to study English.I warned the patient not to eat cold water after the operation.主语宾语表语定语状语宾补(1)作主语不定式做主语时，可以直接放在谓语动词之前。To see is to believe．Not to get there in time is your fault.注：常用it做形式主语，将to do放在位于之后，使句子保持平衡。句型1：It + 谓语 + to doIt takes us an hour ___ get there by bus.句型2：It’s + n. + to doIt’s our duty __ help the poor.It is a great enjoyment __ spend our holiday in the mountains句型3：It is adj. for/of sb. to do sth.It is + adj + for sb to do sthIt is + adj + of sb to do sth（是形容人的品质的 ）（是形容事物的性质的 ）It is easy for me to finish this work before ten.It is a great honor for us to be present at yourbirthday party.It is very kind of you to give me some help.It's impolite of you to speak to the teacher like that.＝You are very kind to give me some help.　＝you are impolite to speak to the teacher like that.　常见动词有：(2)作宾语I want to know this matter.like, demand, expect, promise, begin, determine, refuse, offer, fail, manage, learn, seem, intend, prefer, forget, mean, prepare, pretend, continue, start, afford, hate等I don’t expect to meet you here.1).接不定式做宾语1.

lethavesb. beseenwatchedlooked atheardlistened tofeltnoticed+to domadelet2).I often hear them (sing) this song.Did you notice anyone (come )in ? I would have him (wait) for me for a long time. Look at the horse jump. 注意： 当这类动词转为被动语态时， 其后的不定式则要加上“ to” 如：He is often heard ________ the song· He was seen _______ the room.to singto enter4. it作形式宾语I find/feel to work with him interesting ．I find/feel it interesting to work with him．注意：不定式短语作宾语时，如果还带有宾语补足语，往往把不定式宾语放在宾语补足语之后，而用it作形式宾语。Subject+ find/think/feel/make/ consider… it+adj/n + to do sth.1.We thought ___ better ___ start early. 2.Do you consider ___ better not __ go?3. I feel __ my duty __ change all that.4.We think __ important __ obey the law.5.I know __ impossible __ finish so much

(不定式作定语)不定式与它所修饰的词有动宾关系Do you have anything to wash today?Do you have anything to be washed today?
(区别主被动）不定式用来说明所修饰词的内容I have no chance to go there.被修饰词是不定式的逻辑主语She is the last to leave the room.不定式为不及物动词时，须加介词He is looking for a room to live in.1.The house is not big enough for us all_______.A. to live in　B. to be lived in C. to live D. for living in2. Would you please pass me the knife _______?A. to cut the fruit with　B. to cut the fruit C. cutting the fruit　D. cutting the fruit with3.I have something important to say.please find a piece of paper
（写上）4.Excuse me，could I use your pen for a moment？I have no pen
（写）to write onto write with动词不定式做定语注意： 如果不定式是不及物的，它后面就应有必要的介词。如：He is looking for a room to live in ．Please give me a knife to cut with．(5)作状语表示目的、原因、结果或条件。I came here to see you．We were very excited to hear the news．He hurried to the school to find nobody there .To look at him，you would like him．(目的)(原因)(结果)(条件)动名词（gerund）一. 动名词的基本构成二. 动名词的性质动名词既具有动词的特点有具有名词的特点，具体表现为：1.动名词可以被定冠词和物主代词修饰I hope you don’t mind my saying it.2. 动名词可带有自己的宾语和状语Are you for or against having the meeting.I insisted on leaving at once.三.动名词的功用1.可作主语①Seeing is believingReading newspapers can increase our knowledge.no useno goodno fun② It`s +
+ doinga waste of time/moneyuselessdangerous③ There is no + doing...①It is no use crying.②It is no good objecting③Looking after the patients is a nurse`s job.④It`s dangerous playing with fire.⑤It`s
other`shomework.⑥There is no joking about the matter.2.可作宾语①
S. + vt.+ doingHave you finished reading the book?I suggest doing it in a different way.在某些动词后要求用动名词作宾语，不能用不定式，常见的这类动词有：避免错过 (少) 延期 avoid miss delay/postpone建议完成 (多) 练习 suggest / advise finish practise喜欢想象 禁不住
enjoy/appreciate/ imagine/ resist/can`t help承认 否定 (与) 嫉妒 admit
envy逃脱 冒险 (莫) 原谅 escape / envy /risk /pardon / excuse忍受 保持 (不) 在意
keep / keep on
mind注：在动词advise, allow, forbid(禁止)，permit（允许）等后，如果没有人称宾语，后跟动名词；如果有人称宾语则后跟不定式。例如We don’t allow people to fish here. 我们不准人们在这儿钓鱼。People are not allowed to fish here.人们不准在这儿钓鱼。prefer…..to…..look forward tobe used toput offgive upS. +
doingsucceed incan`t helpfeel likebe busybe worthhave difficulty/trouble/problem (in)②作介词/短语动词的宾语:S. + v. + prep. + doinge.g.①She sat there without (speak)②I look forward to (see) him again.③Are you used to (live) there alone?④When my father heard the news, he couldn't help (laugh).⑤I don`t feel like (go) to see the film.⑥He was busy (prepare) his lessons.③主动表被动:want
(需要)　　　
(需要)　　　　
(需要)Sth. +
doing　　　
(值得)使用动名词作宾语时，用主动形式表达被动含义to be done使用不定式作宾语时，依然用被动形式表达被动含义① The room wants (clean).② The method needs (improve).③ This pair of shoes require (mend).④ The problem needs (work out).⑤ The question is well worth (discuss)d）动词 “like, love, hate, prefer”后接动名词表示“习惯性动作”，后接不定式表示“心理或一次具体动作”。当用在 should, would之后时，只跟不定式。例如：I like swimming, but I don’t like to swim this afternoon.我喜欢游泳，但今天我不愿去游泳。What would you like to eat tonight?你今晚上想吃什么？Stop；forget；try；Mean；go on；Others Examples五.动名词的复合结构动名词前可以加一个 物主代词或 名词所有格来表示 这个动名词逻辑上的主语 ，构成动名词的复合结构或动名词短语1).物主代词 / 名词所有格 + 动名词在句中作主语:Mary`s coming late made her teacher angry.Do you mind my smoking?Do you mind my reading your paper?Their coming to help was a great encouragement to us.Rose’s going won’t be of much help.2).人称代词宾格 / 名词 + 动名词在句中作宾语:I`m sure of him coming on time.He has never heard of a woman being a pilot.I don’t mind Jack (him) going.She hates young people (them) smoking.分词：Participles一 分词的概述1. 分词是“非谓语动词”的另一种形式，它有两种形式：现
在分词（Present Participle）和过去分词（Past Participle）。2. 现在分词：doing过去分词：规则动词 V+ed不规则动词3.分词在句中起形容词和副词的作用。在句中
作表语、定语状语和宾语补足语。现在分词与过去分词的区别：1.语态上：现在分词表主动，过去分词表被动Do you know the woman talking to Tom?The soldier wounded in the war has become a doctor.2. 时态上：现在分词表进行，过去分词表完成Developing country
boiling waterDeveloped country
boiled water二、分词的作用1、作定语分词作定语有两种形式。它可以放在被修饰的名词之前，称为前置定语。有的放在被修饰的名词之后，称为后置定语。（1）前置定语He is a promising young man.
Make less noise. There’s a sleeping child.
We only sell used books.
我们只卖用过的书。（2）后置定语The young man sitting between John and Mary is the editor of the campus newspaper.
现在分词作定语表示动作。如果是单词，放在被修饰的名词前；如果是短语，放就放在被修饰的名词之后。The bridge built last month needs repairing.
上个月建造的那座桥需要修理。（3）分词短语作定语必须置于被修饰词之后，
相当于一个定语从句。如：Those who wish to join the club should sign here(Those wishing to join this club should sign here.
)想加入本俱乐部的人在这里签名。The man,
who had been disturbed so badly, almost lost his memory.)由于被严重困扰，这个人几乎失去了记忆。(The man, having been disturbed so badly, almost lost his memory.（4）过去分词作定语在意义上有两种可能：表示被动和完成，只表完成。如：the question discussed yesterday 昨天讨论的问题
（既表示被动也表示完成）the fallen leaves 落下的树叶
(只表示完成，不表示被动)2、作表语分词作表语表示主语的某种性质或状态。如：She was too frightened to move.她被吓得一动不动。What you said is really inspiring.
你所说的真令从鼓舞。3、作宾语补足语可以跟宾语补足语的谓语动词有 see, watch, hear, set, keep, find, have, get 等词。I saw him walking in the street.我看见他在街上走。I heard them singing in the classroom.我听见他们在教室里唱歌。We found the boy sleeping.我们发现小孩睡着了。A）I heard my brother ( singing , sung ) in the next roomB）I heard the song ( singing , sung ) in English .
现在分词与过去分词在作状语的区别四、作状语现在分词表主动进行，过去分词表被动完成1. (Seeing/seen) from the top of the tower, we can see a beautiful factory.(Seeing/seen) from the top of the tower, the factory looks beautiful.2. (Hearing/heard) the bad news,
they couldn’t help crying.3. (Giving/Given) more time, we could do it better.4.I stood by the door, not daring to say a word. Hearing the bad news,they couldn’t help crying.When theyheard thebad newsGiven more attention,the trees could have grownbetter.If they hadbeen given moreattentionBeing so angry,he couldn’t go to sleep.Because he was so angryThey came into the classroom,singing and laughing.To serve the people well,I study hard.判断下列句子正误：1. To learn English well, a lotof practice must be done.2. Seeing from the hill, the cityis more beautiful.3. Heating , water will boil.4. Getting there, the door wasfound opened.判断句子正误并改正：1, Being ill, his classmate senthim to hospital.2. To get there in time, he toldme to get up early.3,
Broken by Jim, I can’t usethe cup.将下列状语从句改为非谓语短语作状语：1. Because she was moved
bythe hero, she decided tostudy harder.2. When he found the doorlocked, he went home.He started early in order thathe could get there on time.将下列非谓语短语改写为状语从句1. Not knowing her address,I can’t write to her.2. Entering the room,I saw a strange sight.3, Scolded by the teacher,he was very sad.4.Not knowing
where to go,he asked a policeman . 5. Hearing
her friend was bad-ly hurt, she burst into tears.6. Knowing his team hadwon, he became happy at once.不定式时态、语态的用法1. 不定式的动作与谓语动词同时发生时，用一般时态He wanted to see you2. 强调不定式的动作正在进行时，用进行时态When I came in ,he pretended to be reading a bookHe is said to be writing a novel3. 强调 不定式的动作在谓语动词之前发生时，用不定式完成时He is said to have written a novel . I’m so glad to have seen you .The ground is so wet ,It must have rained last night不定式被动语态的用法.A, 当不定式的逻辑主语是不定式的承受者时，用被动语态She asked to be sent to work in Tibet (宾语)The book is said to have been translated into English (
或叫合It is an honor for me to be asked to speak here (主 语)句子的主语是不定式的逻辑主语，尽管不定式与被修饰词是被动关系，也还要用主动语态1, Give him some book to read \Do you have any clothes to wash ?“Do you have any clothes to be washed?” asked the maid2, S +be+easy \difficult \hard \pleasant \interesting \exciting \comfortable +to doThis question is easy to answer The boy is difficult to teach3, The house is to let \The manager is to blame .\The reason isnot far to seek .4There be句型中，主动形式或被动形式均可但有时含意不同There is nothing to do now (we have nothing to do now )现在没事干There is nothing to be done now (we can do nothing now )现在没什么办法There is nothing to see (nothing is worth seeing )没有东西值得看There is nothing to be seen 看不见有什么东西分词时态、语态的用法如果强调分词表示的动作 发生在谓语动词之前，要用完成形式。Not having finished his homework ,Tom was made to stay at school .Having closed all the windows ,I went homeHaving been invited to the party ,Tom was very happy .分词所表示的动作与谓语动词同时发生。分词与其逻辑主语的关系时被动的，要用被动语态1.Looking out of the window, I can see many cars and buses.2.Seen from the top of Dragon Tower, Harbin looks more beautiful.3.The teacher came in, _______many students.(follow)4.The teacher came in, _______by many students.(follow)followingfollowed如果强调分词表示的动作正在进行时，要用分词的进行时态。1. Being repaired, the building is forbidden to enter.2. The house being built now is a Hope Project School.3. Passing by the accident scene, I saw the man badly hurt beingcarried onto an ambulance.Task: complete
the following sentences1.“＿＿＿＿＿＿＿＿＿＿＿＿（你有衣服要洗吗）?the maid asked.2.________________(没有完成作业),Tom was forbidden to watch TV.3.________________(正在刷油漆), the house was not allowed to enter.4.________________(被邀请参加舞会), Mary felt excited.5.The difficult maths problem ____________________(很难算出）.6.She was angry for __________________(没有被邀请）to the ball.7.The thief stole into the store_________________(没人看到）8.The flat _________________(出租）9.The man who was on duty that day _________________(应受谴责）10.They were proud of ____________________(被派往西藏去工作）11.When the teacher came in, Tom _________________(假装再看书）12.Ni Ping is said ____________________(写了一本名叫“日子”的书）13.Song Dandan is said _______________(在写一本叫“月子”的书）14._________________(从窗户往外看), I can see many tall buildings.15._________________(从山顶往下看), the city looks more beautiful.16._________________(他有很多活要干）.Don’t bother him.17._________________(他有很多活要干) and you can go ,too.Do you have any clothes to be washedNot having finished his homework,Being paintedNot having been invited to the ball,is difficult to work outnot having been invitedwithout being seenis to letis to blamehaving been sent to work in Tibetpretended to be readingto have written a book called “The Days”to be writing a book named “ The Months”Looking out of the window,Seen from top of the hill,He has a lot of work to doHe has a lot of work to be done分词的时态和语态构成（以study和go为例）被动式： being done 表示一个现在进行的完成动作。1.The building being repaired is our library.2.The question being discussed is very important.3. As we approached the village, we saw new houses being put up.完成式：having done 所表示的动作在谓语动词所表示的动作之前发生。Having turned off the radio, he began to go over his lessons.2. Not having received his father’s letter, he decided to make a call to him.独立主格结构一般来说，分词或分词短语作状语，其逻辑主语要和句子的主语一致。但有时候，分词的动作不是由句子的主语发出来的，它有自己的逻辑主语。独立主格结构（Independent Genitive）有两部分组成，前一部份是名词或者代词，后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。前后两部分具有逻辑主谓关系。独立主格结构在句中做状语，多用于书面语。　　独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。Given more time, we could do it better.Nobody having any more to say, the meeting was closed.1．独立主格结构的形式：（1）名词 / 代词 + -ing分词及其短语The moon appearing, they decided to go on with their journey.The pupils are walking slowly, their teacher following.（2）名词 / 代词 + -ed分词及其短语Good-bye said, we went home.All things considered, it is a good plan.（3）名词 / 代词 + 形容词及其短语The weather (being) hot, we all went swimming.Dinner ready, the hostess asked her guests to be seated.（4）名词 / 代词 + 不定式及其短语The money to be paid by the driver, the police went away.Here are the first two volumes, the third one to come out next month.（5）名词 / 代词 + 副词及其短语The meeting (being) over, we left the room.（6）名词 / 代词 + 介词及其短语She stood there, book in hand.Everybody at home, we sat down to dinner.2．with + 复合宾语结构这种结构也可以看成是一种独立主格结构。这种结构有较鲜明的特色。在这种结构中，with后的宾语相当于该结构中的逻辑主语，其后面的词相当于这个结构中的逻辑谓语。这个结构很像一个用来说明附带情况或细节的，可以起状语作用的句子。翻译时，with原有的含意往往不翻译出来。（1）with + 名词 / 代词 + 名词The brave man fought the tiger with a stick his only weapon.He was carried into the hospital, with his face a mass of bleeding flesh.（2）with + 名词 / 代词 + 介词The teacher came into the classroom with a book in his hand.He was asleep with his head on his arms.Family dependants, when ill, enjoy free medical treatment, with medicines at half price.（3）with + 名词 / 代词 + 副词He went out with his hat on.The square looks more beautiful than ever with her lights on.4）with + 名词 / 代词 + 形容词Don’t speak with your mouth full.The once lowly serfs now walk with heads high.5）with + 名词 / 代词 + -ing分词With the old man leading, the two started toward the mountains.With everyone surrounding us we can certainly succeed.She felt very nervous with so many people looking at her.（6）with + 名词 / 代词 + -en分词All the afternoon he worked with the door locked.He died with his life’s work still unfinished.With his matter settled, we left the room.（7）with + 名词 / 代词 + 不定式They are highly mechanized farms, with machinery to do most of the work.This was a severe test, with innumerable difficulties to be overcome.With five minutes to go before the last train left, we arrived here.3.由There being +主语这种结构多表示原因。例如：There being a lot of books to read, he often studied till midnight.因为有许多书要读，他经常学习到深夜。不定式与动名词作主语的区别：不定式作主语时经常表示具体动作，而动名词作主语时经常表示抽象动作： It’s no good eating too much fat.It’s not good for you to eat so much fat.关于逻辑主语的问题动名词复合结构的一般规则是：1.逻辑主语是有生命的名词：作主语时，须用名词所有格或形容词性物主代词；作宾语时，也可用普通格或人称代词宾格。Tom’s (His) coming is what we have expe2. 逻辑主语是无生命的名词：Is there any hope of our team winning the matchShe didn’t mind Jack/ Jack’s (him/ his) coming here.1. ______to the meeting surprised all of the boards.A. Mike coming
B. Mike cameC. Mike comes
D. Mike’s coming2. It’s no use _______ that you didn’t know the
rules.A. you pretend
B. you pretendingC. your pretending
D. your pretendChange the following into the simple sentences.That Peter didn’t attend the meeting made it put off.Thanks a lot!不定式与动名词作主语的区别：不定式作主语时经常表示具体动作，而动名词作主语时经常表示抽象动作： It’s no good eating too much fat.It’s not good for you to eat so much fat.关于逻辑主语的问题动名词复合结构的一般规则是：1.逻辑主语是有生命的名词：作主语时，须用名词所有格或形容词性物主代词；作宾语时，也可用普通格或人称代词宾格。Tom’s (His) coming is what we have expe2. 逻辑主语是无生命的名词：Is there any hope of our team winning the matchShe didn’t mind Jack/ Jack’s (him/ his) coming here.1. ______to the meeting surprised all of the boards.A.

D. Mike’s coming2. It’s no use _______ that you didn’t know the
rules.A. you pretend
B. you pretendingC. your pretending
D. your pretendChange the following into the simple sentences.That Peter didn’t attend the meeting made it put off.不定式、动名词用作主语1。直接作主语（1）眼见为实（2）今天早晨做早操对身体
无益（3）在这里吸烟很危险1.To see is to believe2.To do morning exercises today is not good for health.3.To smoke here is dangerous（1）眼见为实。（2）天天做早操有益于健康。（3）吸烟不是好习惯。1.Seeing is believing.2.Doing morning exercises every day is good for health3.Smoking is not a good habit不定式与动名词作主语的区别：不定式作主语时经常表示具体动作，而动名词作主语时经常表示抽象动作A: 如果要说明不定式表示的动作是谁做的，可以在不定式前加一个由 for 引起的短语。It is easy for the students to read.It will be a mistake for us to help you.B: 下列形容词作表语时，不定式前常加一个 of 引起的短语，这些形容词是：(表评价性的，来说明逻辑主语的性质，特征，属性）kind, good, nice, wise, unwise, clever, silly, stupid, foolish, wrong, right, careless, rude, polite,naughty etc.It’s kind of
