    高中if從句教案【篇1】
    高中英語賓語從句課件
    
    賓語從句(object clauses)
    1、概述用作賓語的從句叫做賓語從句。賓語從句的位置與陳述句基本結(jié)構(gòu)中的賓語相同。賓語從句可作謂語動詞的賓語，也可以作介詞和非謂語動詞（動詞不定式、動名詞、分詞）和某些形容詞的賓語。賓語從句可以由從屬連詞that whether、if，關(guān)系代詞what, who, whose, which和關(guān)系副詞when、where、how、why等引導(dǎo)。
    He said he wanted to go to town.他說他想去城里。
    I hope you'll be better soon.我希望你能很快好起來。
    I’m so glad that you were able to come to this party.你能設(shè)法抽空出席這個交際會，我很高興。
    I know nothing about it except what I have read in the papers.除了在報上讀到的以外,我對這件事一無所知。
    Most of the Chinese people usually go to work on the bike except when it rains.除了雨天,大多數(shù)中國人一般都騎自行車上班。
    He asked me whether she was coming.他問我，她來還是不來。
    2、作動詞賓語
    （1）由從屬連詞that引導(dǎo)的賓語從句。that引導(dǎo)賓語從句時，只起引導(dǎo)詞作用，在句中不做成分，在口語和非正式文體中常省去。
    I think (that) he'll be right in a few days.我認(rèn)為他幾天后就會好的。
    I wish（that）she would understand me.我希望她理解我。
    （2）由關(guān)系代詞what, who, whose, which引導(dǎo)的賓語從句，在句中作成分，即主語、賓語、表語和定語，關(guān)系代詞在句中不能省略。
    A computer can only do what you have instructed it to do．計算機(jī)只能按人的指令去做。
    Do you know whom they are waiting for?你知道他們在等誰嗎？
    He asked whose dictionary it was.他問這是誰的字典。
    He can't tell which method they will use for the experiment.他不能斷定他們會用哪一種方法做實驗。
    （3）關(guān)系副詞when，where，how，why等引導(dǎo)賓語從句。關(guān)系副詞when，where，how，why既有疑問意義，又起連接作用，而且在賓語從句中充當(dāng)各種狀語，分別表時間、地點、方式、原因。在句中不能省略。
    Please tell me when we shall discuss our plan.請告訴我我們將何時討論計劃。
    I don't know where we are going to have the meeting.我不知道我們將在哪里開會。
    Will you tell me how I can get to the station？你能告訴我如何能到車站嗎？
    Do you know why he said that?你知道他為什么說那件事嗎？
    I remember when this used to be a quiet village．我記得這里曾經(jīng)是一個僻靜的村莊。
    （4）由從屬連詞whether或if引導(dǎo)的賓語從句。
    I wonder whether (if) daughters are valued as much as sons in the countryside.我想知道在農(nóng)村女兒是否和兒子一樣受到重視。
    I don't know whether (if) you are willing to help me.我不知道你是否愿意幫我。注意：whether和if的區(qū)別，請參考概述部分。（5）動詞+間接賓語+賓語從句。動詞如：advise, ask, inform, promise, question, remind, show, teach, tell, warn等，賓語從句前可以有一個間接賓語，這個賓語有時可以省略，有的不能省略。
    He has informed me when they are to discuss my proposal.他已經(jīng)通知我們將什么時候討論我的建議。(me不可省略)
    She promised (us) that she would give us more help later on.她答應(yīng)以后給我們更多的幫助。(us可省略)
    3、作介詞賓語
    It depends on whether he is coming or not.這要看他是否會來。
    I was curious as to what we could do next.我想知道下一步我們該做什么。注意：that引導(dǎo)的賓語從句只在in, but, except, besides等少數(shù)介詞后作賓語，形成固定搭配，in that在于（因為），but that要不是(只是)，except that除了……。
    The higher income tax is harmful in that it may discourage people from trying to earn more.所得稅過高是有害的，因為它可能使人不愿多賺錢。
    His paper is perfect except that there were some misprints.除了一些印刷錯誤之外，這篇論文很好。
    4、作形容詞賓語。
    No one can be sure what man will look like in a million years．誰也不知道一百萬年后人類會變成什么樣子。
    I am not certain whether I have met him before.我不能肯定從前是否見過他。
    I'm sorry (that) you're ill.你病了，我很難過。注意：that引導(dǎo)的從句在下列形容詞后面作賓語，that可以省略。anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content, proud等。
    I'm sure (that) he'll help you.我確信他會幫助你。
    I'm glad (that)he has passed the exam.我很高興，他考試及格了。
    5、it充當(dāng)形式賓語，真正的賓語---賓語從句后置。正如我們常用it充當(dāng)形式主語代替主語從句一樣，我們也常用it用作形式賓語代替賓語從句，把真正的賓語從句后置。特別是帶復(fù)合賓語的句子中。在這種結(jié)構(gòu)中that不可省略。有下列幾種情況：（1）在believe, consider, declare, estimate, fancy, feel, find, guess,hear, imagine, know, make, prove, reckon, think, understand等動詞接復(fù)合賓語（賓語＋賓補(bǔ)）時，要用it作形式賓語。
    We find it difficult that we should finish the work on time．我發(fā)現(xiàn)我們按時完成工作有困難。
    She thinks it wrong that he didn't answer the phone．她認(rèn)為他不接電話是不對的。
    （2）在like，enjoy，love,hate,take等表“喜怒哀樂”的動詞，后若要跟賓語從句時，需跟形式賓語it。
    I hate it when people talk with their mouths full.我不喜歡人們滿口飯說話。
    I like it that everyone passed the exam．都通過了考試我很喜歡。
    （3）由動詞和介詞構(gòu)成的短語動詞后接that賓語從句時，要用形式賓語。
    We are thinking of it that we'll lend you some money．我正在考慮借給你錢的事。
    I shall see to it that he is taken good care of when you are absent.你不在的時候我負(fù)責(zé)把他照顧好。（4）用于“動詞+賓語+介詞短語”的句型中。
    Keep it in mind that you have to be home by ten o’clock.要記住你得十點鐘之前回家。
    We took it for granted that he would come.我們認(rèn)為他來是當(dāng)然的'。
    6、不可直接跟that從句的動詞。下列動詞不可直接接that從句：ask, refuse, let, like, cause, force, condemn, admire, entreat, dislike（厭惡）, overlook, love, help, take, forgive, bid, hate, hear（聽見）, see（看見）, want（想要）等，但可用it, the fact做媒介，后接that從句；或接動名詞、不定式。
    He overlooked it that he had made another mistake.(正確)他忽視了一件事，他又犯了一個錯誤。
    He overlooked the fact that he had made another mistake. (正確)
    He overlooked that he had made another mistake.(錯誤)
    I admire it that they won the match. (正確)
    I admire the fact that they won the match. (正確)我很羨慕，他們贏得了比賽。

    7、that引導(dǎo)賓語從句的省略。（1）主句謂語動詞是agree, argue, hold, learn, maintain, observe, contend, conceive, reckon, remark, state, suggest, assume, announce, calculate, indicate等時，其后賓語從句的引導(dǎo)詞that一般不可省略；主句謂語動詞是hear, know, say, see, confess consider, declare, understand, propose等時，其后賓語從句的引導(dǎo)詞that可以省略，也可以不省略；主句謂語動詞是think, suppose, believe, presume, dare say等時，其后賓語從句的引導(dǎo)詞that可以省略。
    He suggested that we should set off at 8 o’clock tomorrow morning.他建議我們明天早晨8點走。(that不可省略)
    I think (that) this is very important.我認(rèn)為這很重要。(that可省略)（2）當(dāng)一個句子很復(fù)雜，句中有多個狀語時，that不可省略；或者一個句子有多個并列的賓語從句時，特別第一個賓語從句特別長，后面的賓語從句的that不可省略；謂語動詞與that從句之間有插入語時，that不可省去。
    He said you needn't worry and that he would help you .他說你沒有必要著急，他會幫助你的。（said之后可省去that，但第二個that不可省去）
    We decide, as he has suggested, that we will start out tomorrow.就像他建議的那樣，我們決定明天動身。
    8、否定轉(zhuǎn)移與省略（1）如果主句的謂語動詞是“think, consider, suppose, believe, expect, fancy, guess, reckon, imagine等，主語是第一人稱的一般現(xiàn)在時態(tài)，其后的賓語從句如含有否定意義，一定要把否定詞一道主句謂語上，從句謂語動詞用肯定形式。
    I don’t think he can do it better than me.我想他不會比我干得好。
    I don’t believe he treated the child like that.我相信他不會那樣對待孩子的。
    （2）如果think, consider, suppose, believe, expect, fancy, guess, reckon, imagine等前有副詞或表示強(qiáng)調(diào)的do, does, did；或者同其它詞構(gòu)成并列謂語；或者不以現(xiàn)在時出現(xiàn)；或者用作插入語中。這時候不用否定轉(zhuǎn)移。
    I really expect she didn’t say that to him.我確實希望她不和他說那件事。
    I think and hope that he won’t be deceived by the man.我認(rèn)為也希望他不會被那個人欺騙。
    （3）think, consider, suppose, believe, expect, fancy, guess, reckon, imagine等此類動詞后，在簡略答語中，用so替代前文肯定的賓語從句；若替代一個否定的賓語從句，用not或not…so替代前文整個從句。
    -I believe we've met somewhere before．我認(rèn)為我們從前在哪見過。
    -No，I don't think so．沒有，我認(rèn)為我們以前沒見過。
    -Do you think it's going to rain over the weekend？你認(rèn)為這周末會下雨嗎？
    -I believe not．我認(rèn)為不會。注意：hope只能說I hope not一種形式，因為hope不能否定轉(zhuǎn)移。
    9、時態(tài)的呼應(yīng)與語序。
    在賓語從句中只能用陳述句語序，時態(tài)呼應(yīng)上要遵循以下三條原則：（1）如果主句謂語是一般現(xiàn)在時或?qū)頃r，賓語從句的謂語可根據(jù)意思的需要使用任何一種時態(tài)。
    Can you make sure where Alice has put the gold ring？你能確定愛麗絲把金戒指放到什么地方了嗎？
    They have no idea at all where he has gone．他們一點也不知道他去了哪。
    Do you know who he was talking with at eight last night？你知道他昨晚和誰一起說話嗎？
    （2）如果主句謂語是一般過去時，賓語從句要用表示過去的某一時態(tài)。
    He said he would come to see us the next day.他說他明天將來看我們。
    I wanted to know whether he had been to Beijing.我想知道他是否去過北京。
    （3）如果賓語從句是表示客觀事實、真理等，不管主句是什么時態(tài)，賓語從句一律用一般現(xiàn)在時。
    Dick asked Lucy how old she is．迪克問露斯她多大了。
    The teacher said the sun rises in the east．老師說太陽從東方升起。
    要點
    一、高中賓語從句要點之時態(tài)的呼應(yīng)
    1.如果主句是一般現(xiàn)在時、一般將來時或祈使句時,賓語從句可根據(jù)情況使用各種時態(tài)。例如:
    I hear she is here today(she was here yesterday/ she will be here tomorrow.)
    2.如果主句是一般過去時,賓語從句應(yīng)使用過去時態(tài)的某種形式。例如:
    He said he was watching TV(he had swept the floor/ he would play football after school)。
    3.如賓語從句所敘述的是客觀事實、自然現(xiàn)象或科學(xué)真理等,從句不受主句時態(tài)限制,仍用一般現(xiàn)在時。例如:
    Our teacher told us that light travels faster than sound.
    二、高中賓語從句要點之引導(dǎo)詞的使用
    1.當(dāng)賓語從句由陳述句變化而來時,用that來引導(dǎo)從句,that常無具體意義,一般可省略。例如:
    Lin Tao thought(that)the TV play was very boring.
    2.當(dāng)賓語從句是由一般疑問句變化而來時,要用if或whether來引導(dǎo)從句。例如:
    David asked his mother if/ whether she liked the dinner last night.
    3.當(dāng)賓語從句是由特殊疑問句變化而來時,原句中的疑問詞充當(dāng)連接代詞(如who, whose, what, which)或連接副詞(如when, where, why, how),引導(dǎo)賓語從句。例如:
    Do you know what we can do on the island?
    I don’t know why Jane was late for school this morning.
    三、高中賓語從句要點之語序的陳述化
    賓語從句一般要用陳述句語序。例如:
    When did he leave? I want to know. →I want to know when he left.
    Does the shop close at six every day? Do you know? →Do you know if/ whether the shop closes at six every day?
    四、高中賓語從句要點之否定轉(zhuǎn)移
    當(dāng)主句的謂語動詞為think, believe, suppose等動詞,且主語為第一人稱時,從句的否定要轉(zhuǎn)移到主句上。例如:
    I don’t believe he is here on time, is he?
    I don’t think Tom is the best student in his class, is he?
    高中if從句教案【篇2】
    語序為v.+主語+謂語+由if、whether引導(dǎo)賓語從句；
    連接賓語從句的從屬連詞主要有that,if,whether，和疑問詞（what， how， where， when ...)。
    that引導(dǎo)表示陳述句的賓語從句，
    if和whether，whether...or not引導(dǎo)表示“是否”的一般疑問句的賓語從句。
    連接代詞主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。
    連接代詞一般指疑問，但what,whatever除了指疑問外，也可以指陳述。
    連接副詞主要有when,where,why,how,whenever,wherever,however等。
    例句：
    He didn’t tell me when we should meet again.
    他沒有告訴我什么時候我們能再見面。
    大多數(shù)及物動詞都可以帶賓語從句。
    部分“動詞+副詞”結(jié)構(gòu)也可以帶賓語從句。
    動詞短語也可以帶賓語從句，常見的這些詞有：
    make sure（確保）、make up one’s mind（下決心）、keep in mind（牢記）
    ①動詞find,feel,consider,make,believe,think等后面有賓語補(bǔ)足語的時候，則需要用it做形式賓語而將that賓語從句后置。
    ②有些動詞帶賓語從句時需要在賓語從句前加it（雙賓語）這類動詞主要有：hate,take,owe,have,see to.award,lend.hand,mail,offer,pass,pay,post,read,return,show,teach,tell
    用whether之類的介詞賓語從句。
    用that,if引導(dǎo)的介詞賓語從句，有時候except,but,besides三個介詞后可見到that引導(dǎo)的賓語從句。
    有些形容詞具有動詞的含義，所以也可以帶一個賓語從句；
    例句：
    I am sorry I am late.
    I am glad that you can join us.
    Are you sure his answer is right?
    常用來引導(dǎo)賓語從句的形容詞有：sure,certain,glad,pleased,happy,sorry,afraid,satisfied,surprised
    if和whether在作“是否”理解時，引導(dǎo)賓語從句常放在動詞know,ask,care,wonder,find out等之后，介詞后一般不用if。
    少數(shù)動詞，如：leave,put,discuss,doubt后的賓語從句常用whether。
    whether后可以加or not,但是if不可以。
    在不定式前只能用whether。
    一般“no matter”后表示“是否”用whether而不用if。
    存在以下情況時引導(dǎo)詞that不可省略：
    that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等動詞的賓語。
    高中if從句教案【篇3】
    教學(xué)過程
    1、對上節(jié)課課后作業(yè)中的問題進(jìn)行查漏補(bǔ)缺；
    2、導(dǎo)入：
    e.g. She is a beautiful girl.
    She is a beautiful girl who drives me crazy.
    1、定語從句：在復(fù)合句中，修飾某個名詞或代詞的句子（做這個名詞或代詞的
    定語）叫定語從句，定語從句一般放在被修飾的名詞或代詞后面。
    關(guān)系代詞的種類：
    關(guān)系代詞：that, which, who, whom, whose, as
    a、There she saw a wall of water that was quickly advancing towards her.
    b、 In Japan, someone who sees another person making the gesture will think it means money.
    c、Visitors can go on exciting rides where they can feel what it is like to do the things they have seen their heroes do in the movie.
    d、Oprah Winfrey is a black woman whose rise to fame is an inspiring story.
    限定性定語從句：從句對先行詞進(jìn)行必要的描述或說明，對先行詞起修飾限定作用，從句與先行詞緊密相連，缺少它則句義顯得不完整，一般不用逗號隔開。 非限定性定語從句：對先行詞進(jìn)行補(bǔ)充說明，解釋，它與先行詞關(guān)系松散，用逗號隔開。
    1、The man who gave me this book is Tom .(限定性)
    2、Tom,who is reading a book ,is my classmate (非限定性)
    1、who指人，在定語從句中作主語。
    e.g. The man who is sitting under the tree is a German .
    2、Whom指人，在句中做賓語，可省略，但在做介詞的賓語是只能用whom,不能用who。關(guān)系代詞前有介詞時不能省略。
    e.g. I know the girl (whom) the teacher is speaking to .
    I know the girl to whom the teacher is speaking .
    e.g. Everyone heplps the child whose parents are dead.
    Theyare the lazy students whose homework wasn’t handed in .
    4、that 指人或物，多指物，作主語（不能省略）或賓語（可省略）
    e.g. He is the finest comrade that has helped us .
    This is a plant that grows in the north .
    5、which ,指物，在句中做主語（不能省略），或賓語（可省略）。
    e.g. This is a plant which grows in the north .
    1、當(dāng)先行詞是all, everything, anything, nothing, much, little, none, one等不定代詞時，只用that。
    Pay attention to everything that I do.
    2、當(dāng)先行詞被序數(shù)詞或形容詞最高級修飾時，只用that。
    This is the best novel (that)I have read.
    3、如果出現(xiàn)兩個或兩個以上的先行詞，并同時兼指人和物時，關(guān)系代詞用that。 歌訣助記：兩項并列人與物，引導(dǎo)定從用that。
    They were talking about the person and things that they remembered in school.
    4、當(dāng)先行詞被the only, the last, the way, the same等修飾時。
    This is the last time that I shall give you a lesson.
    5、在疑問詞which開頭的特殊疑問句中，為了避免重復(fù)只用that。
    Which of the students that knows something about history.
    6、當(dāng)被修飾的成分是數(shù)詞時，（被修飾成分是代名詞one，指人時除外）只用that. I’ve got one that you might be interested in.
    1、引導(dǎo)非限制性定語從句。
    Football, which is an interesting game, is played all over the world.
    全世界都踢足球，它是一項有趣的運(yùn)動。
    2、直接放在介詞后作賓語時（介詞+關(guān)系代詞結(jié)構(gòu)中）。
    Language is the most important tool without which people can't communicate with each other.語言是最重要的工具，沒有它，人們便無法交流。
    （1）在定語從句中作狀語，先行詞主要為一些時間名詞（year ,day ,time,week等）,但時間名詞在從句中作主語，賓語時，應(yīng)用that，which，不能用when
    e.g. I’ll never forget the time when (during which ) we worked on the farm.作狀語 I still remember the day that/which is his birthay.做主語
    He regretted the days that /which he spent on play . 做賓語
    （2）It is the first time that …句型中，that是習(xí)慣用法，不用when。
    e.g. It is the first time that I have been to the Great Wall .
    （1）指前面的地點，在從句中作狀語。
    e.g. I know the factory where I worked twenty years ago .
    （2）指地點，在句中作主語，賓語時不能用where，須用that/which .
    e.g. This is the house where he has lived for 20 years （作狀語）.
    This is the house that he has lived in for 20 years .（作賓語）
    e.g. This is the shool ｛in which /where we study every year.（作狀語）
    This is the shool that /which we visited yesterday. （作賓語） .
    “the reason why ….that…. ”中，不能用because 代替that .
    e.g. That’s the reason why (for which ) he didn’t come to school .
    The reason why he didn’t attend the meeting is that he was ill .
    但reason 在從句中做賓語時，關(guān)系代詞用that/which ,可省略
    e.g. I don’t believe the reason (which/that) he gave me .
    當(dāng)先行詞在定語從句中作介詞的賓語時，往往可以把介詞放在關(guān)系代詞之前，構(gòu)成“介詞+關(guān)系代詞（whom/which）”結(jié)構(gòu)。但一些短語如look after 等中的介詞不能與動詞分開，故不能放在關(guān)心代詞之前。確定介詞時：
    一是，依據(jù)定語從句中動詞所需要的某種習(xí)慣搭配；
    二是，依據(jù)先行詞的某種習(xí)慣搭配；
    三是，根據(jù)所要表達(dá)的意思來確定。
    e.g. That’s the reason why (for which ) he didn’t come to school .
    關(guān)系代詞在非限定性定語從句中的用法。
    指人做主語用who,作賓語用whom ，指地點用where，指時間when，指物只用which，不能用that，作定語用whose。
    e.g. He didn’t see the film, which was very interesting .(不用that)
    such ….as： 像….一樣的，像…..之類；the same…as： 和…..同樣的
    在這兩個句型中，as是關(guān)系代詞，such和same 作定語，修飾主語里的某個名詞（或代詞），這個名詞是由as引導(dǎo)的定語從句的先行詞，as在從句中可擔(dān)任主語、賓語或表語。
    Eg： We have found such materials as are used in their factory.( 在從句中作主語) I seldom give my students such a difficult problem as they cannot work out.（在從句中作賓語）
    The result is not the same as they had expected.( 在從句中作賓語)
    重點比較 :
    the same …as…和 the same …that…
    兩者都引導(dǎo)定語從句。as 從句中說明的名詞與the same 修飾的名詞是同一類，而非同一個。that從句中說明的名詞與the same 修飾的名詞是同一個。
    Eg：He is reading the same book that you bought yesterday.
    He is reading the same book as you bought yesterday.
    This is the same pen that I lost. =This is the pen that I lost.(指同一支筆)
    This is the same (kind/type/sort) of pen as I lost.（指同類型的筆，但并不是我丟失的那一支）
    ….such as …中的such為代詞，意思是“這樣的人或物”，as 在從句中作賓語，修飾先行詞such。
    Eg： This book is not such as I expect.
    He told me of his experience such as I had never had before.
    相關(guān)鏈接：
    such as 還有“諸如，例如，像…那樣的”的意思，此時后面跟名詞或名詞短語等。
    Eg：They bought a lot of fruit, such as apples,oranges,etc.
    as 可以像which一樣引導(dǎo)非限制性定語從句，用來代表整個句子的內(nèi)容，它的先行詞可以是名詞，也可以是不定式短語或整個句子。as 在從句中作主語、賓語和表語。此外，有些as 引導(dǎo)的定語從句已成為固定用法，如：
    As we know As has been said before 如上所述 As is known to all As is often the case 像通常那樣 As is reported As was expected 正如預(yù)料的`那樣 Eg： She is very careful, as her work shows.
    As we know, smoking is harmful to one’s health.
    As is often the case, we have worked out the production plan.
    重點比較：as 和which 引導(dǎo)的非限制性定語從句的聯(lián)系和區(qū)別
    1、as 和which 都可以代替整個句子，當(dāng)定語從句置于主句之后時，as和which可以和互換。
    Eg：He didn’t tell me any news, as/which upset me.
    2、Which引導(dǎo)的從句，代表的前面的整個主句時，不能放在主句之前。而as 引導(dǎo)的定語從句，代表整個主句時，可以放在主句之前或之后，有時也可以放在主語和謂語之間。
    Eg：As is reported in the newspapers, talks between the two countries are making progress.
    = Talks between the two countries, as is reported in the newspapers, are making progress.
    As 引導(dǎo)的定語從句表示它的內(nèi)容與主句所講的內(nèi)容相似，即指同類事物；that 引導(dǎo)定語從句表示的內(nèi)容與主句相同，即為同一事物。

    （3）在表示建議 suggest , advise 要求demand 、desire、require、request、propose； 決定 decide; 命令 order、command; 堅決主張 insist; 等動詞后跟賓語從句，用（should）+v．（虛擬語氣）
    eg． I suggested that you（should）study hard． He ordered that we should go out at once．
    （4）如果賓語從句后有賓語補(bǔ)語，用it作形式賓語，把賓語從句后置
    eg．You may think it strange that he would live there．
    A．當(dāng)主句謂語動詞帶有兩個或兩個以上賓語從句時，可以省略第一個that，其他不能省略。
    eg．I believe（that）you have done your best and that things will get bet?．
    eg．She made it clear that she had nothing to do with him．
