新版9B復(fù)習(xí)講義新版9BUnit1 Asia 復(fù)習(xí)講義一、重點(diǎn)詞匯重點(diǎn)詞語搭配compare.to. “把比作”connect A with B “將A和B相連接”compare.with “把和比較”connect A to B “將A連接到B上面”start with= begin with “以.開始”make sb. calm down “使某人鎮(zhèn)定下來”take the place of “代替”make sb. feel very ill “使某人感到非常難受”二、語法點(diǎn)撥1. can,could,may,might表示許可can / could / may / might均可表示許可，只不過may較側(cè)重講話人的許可，而can較側(cè)重客觀情況的許可；could / might的語氣比can / may更委婉、客氣；在答語中表示允許別人做某事要can / may，不能用 could / might。如：-Could Can, May, Might I use it? 我可以借用它嗎?- Yes, you can may. 可以。（不用 could / might）must表示必須作某事，其否定式mustnt表示“不可以”。如：We must not speak of it again. 我們?cè)僖膊灰勥@事了【小試牛刀】1.-Could I use your dictionary? -Yes，of course you _.

Here you are.( 2013桂林市) A. MayB. WouldC. NeedD. Must2. 賓語從句(1) 定義： 用作賓語的從句叫賓語從句。賓語從句可以用連詞that，連接代詞who，whom，what，which；連接副詞 how，when，where以及if和whether引起。連接代詞和連接副詞在賓語從句中作一相應(yīng)的句子成分，if或whether表示疑問，而that沒有意義僅起連接作用。(2) 賓語從句的分類： 作動(dòng)詞的賓語從句：Everyone knows that he is a good student.He wondered how the pyramids were built. 作介詞賓語：This depends on how hard you work.Is there anything wrong in what I said? 作形容詞的賓語：They are confident that they can do the job well.I am not certain whether the train will arrive on time.(3) 使用賓語從句要注意的問題： 賓語從句引導(dǎo)詞that的省略：在非正式場(chǎng)合下，that在引導(dǎo)賓語從句時(shí)，可以省略。如：I think (that) you are right. 形式賓語it：如果賓語從句后面跟有補(bǔ)語，要用形式賓語it來代替，而將從句放到補(bǔ)語的后面去。如：He has made it clear that the meeting will not be postponed. I heard it said that that factory was founded in 1901. 賓語從句的時(shí)態(tài)呼應(yīng)：如果主句的謂語是過去時(shí)，賓語從句的時(shí)態(tài)要按照時(shí)態(tài)呼應(yīng)規(guī)則進(jìn)行相應(yīng)的調(diào)整。但是若賓語從句表示的是客觀真理或自然觀念，其謂語時(shí)態(tài)仍用一般現(xiàn)在時(shí)。如：He said that he had left his umbrella in the library. The teacher told the students that the Pacific Ocean is the largest ocean in the world. 賓語從句否定意義的轉(zhuǎn)移：在think, believe, suppose, expect 等動(dòng)詞所根的賓語中，如果從句謂語是否定的，一般要將否定詞not轉(zhuǎn)移至主句謂語上去，而將從句賓語變?yōu)榭隙ㄐ问?。如：I dont think he has time to play chess with you.I dont suppose it is the rush hour yet. 一些動(dòng)詞接的賓語從句通常要用虛擬語氣：一般說來，在一些表示堅(jiān)持(insist)，命令(order，command)，建議(suggest，advise)，要求(require，demand) 等動(dòng)詞之后的賓語從句中，謂語一般要用“should +動(dòng)詞原形”（其中的should在美國(guó)英語中常省略，但是引導(dǎo)從句的that通常不省略。如：She suggested that we (should) leave earlyHe ordered that the medicine (should) be sent by a special plane whether 與 if 引導(dǎo)介詞賓語從句時(shí)，只用 whether不用if；與“or not”連用時(shí)，用whether不用if。 I am interested in whether hell go abroad We dont know whether he will come or not 賓語從句的語序 連接詞后面為陳述語序。如：I dont know what your name is. 直接引語變?yōu)殚g接引語 間接引語的使用應(yīng)注意選擇合適的動(dòng)詞。陳述用say/tell，疑問用ask/wonder，而祈使用tell/order，建議用advisesuggest。注意這些動(dòng)詞后面的結(jié)構(gòu)和語氣。如： “Could you get some tea for me？” MrBlake said to his wife Mr. Blake asked his wife whether she could get some tea for him. “Shall we go dancing tonight？”John said John suggested they should go dancing tonight. 【真題演練】1.-Excuse me .Could you tell me_I can get to the Space Museum?-Of course.You can take bus No.1.

In order to catch the first bus,he got up very early.（此時(shí)不能用so as to） 【注意】 in order to 一般用in order that加從句來替換；而so as to 一般用so that加從句來替換。in order that 可以在句首，so that和so as to 一樣不能在句首。 當(dāng)這兩個(gè)短語后的不定式動(dòng)詞的邏輯主語和句子的主語一致時(shí)，“in order to , so as to +不定式”可以簡(jiǎn)化為“不定式” In order to get to school on time, he got up earlier.這個(gè)句子可以表達(dá)為下列幾種方式：In order that he could get to school on time,. He got up earlier in order to get to school on time. He got up earlier in order that he could get to school on time. He got up earlier so as to get to school on time. He got up earlier so that he could get to school on time. To get to school on time, he got up earlier. （這種不定式有時(shí)可以表示目的以外的狀語）2. as a resultas a result是一個(gè)習(xí)慣短語，意為“因此” “結(jié)果”。如： As a result, the discussion was put off until the following week. 結(jié)果討論被推遲到了下星期。 He didnt practice, and as a result he lost. 他沒有練習(xí)，所以輸了。 The traffic was very heavy and as a result we didnt arrive on time. 交通十分擁擠，因此我們沒能準(zhǔn)時(shí)到達(dá)。 as a result of意為“因?yàn)椤?“由于” “的結(jié)果”，用來作狀語。如： He is unable to go to work as a result of the fall off the horse. 由于他從馬上摔了下來，他不能去上班了。 He was late as a result of the heavy snow. 他遲到是由于大雪所導(dǎo)致的。 As a result of warning, nobody was hurt. 由于得到了警告，因此沒有人受傷3. need to(1) need作情態(tài)動(dòng)詞的用法：need用作情態(tài)動(dòng)詞時(shí)表“必須必要”的意思，后直接跟動(dòng)詞原型，且need無人稱、數(shù)的變化（第三人稱單數(shù)不加s），也沒有非謂語形式（不定式、分詞）。 【注意】need用作情態(tài)動(dòng)詞時(shí)常用于否定句和疑問句中。例：Needhebringhislaptoptomorrow?明天他必須帶他的筆記本過來嗎？Comeon,youneedntworryaboutitbecuseitsnotyourfault.行啦，你不必?fù)?dān)心的因?yàn)槟遣皇悄愕腻e(cuò)。Sheneednthavearrivedsoearly,needshe?她本不必到得這么早，不是嗎？ 【注意】must引導(dǎo)的一般疑問句的否定回答必須使用neednt。例如：-MustIleave?我必須離開嗎？-No,youneednt.不，你不必離開。(2) need作實(shí)意動(dòng)詞的用法： 人+ need+something需要某物Ineedsomefruitstoeat.我需要些水果來吃。 人+ needtodosomething需要做某事Youdontneedtohavethebikerepairedrightaway.你不必馬上去修車。 物+ needdoing=needtobedone需要Theroomneedscleaning=Theroomneedstobecleaned.房間需要打掃了。 人+ needsomebodytodosomething需要某人做某事Ineedsomeonetohelpmeoutofthisproblem.我需要找人來幫助我解決這個(gè)問題。(3) need作名詞的用法：need用作名詞時(shí)，既可以是可數(shù)名詞，也可以是不可數(shù)名詞。主要常用句型如下： (Theres)noneedtodosomething沒必要做某事Theresnoneedtocoversuchalongdistance.沒必要走那么遠(yuǎn)的距離。TheresnoneedformetobreakthewindowbecauseIhavethekey.我沒必要打破窗戶因?yàn)槲矣需€匙。Noneedtorunsincewerenotpressedfortime.不必跑啦，我們又不趕時(shí)間。也可以單獨(dú)使用：Theresnoneed.意思是“沒有必要”。 in(great)needof（非常）需要Therescueteamisingreatneedofmedicine.救援小組非常需要藥品。 ifneedbe如果需要的話Ifneedbe,Imgoingtodoyouafavor.如果需要的話我會(huì)幫你的。(4) 關(guān)于need的一些短語、俚語用法。Afriendinneedisafriendindeed.患難之交才是真朋友?！菊骖}演練】1. -Theres too much salt in the Chinese diet. -So there is.

(=Though he works hard, he makes little progress.)盡管他學(xué)習(xí)很努力，但幾乎沒取得什么進(jìn)步。 Child as/though he was, he knew what was the right thing to do.（=Though he was a child, he knew what was the right thing to do.）雖然他是一個(gè)孩子，但他知道該做什么。 Fast as you read, you cant finish the book so soon. 縱然你讀得快，你也不能這么快讀完這本書。 （3）even if, even though 表示“即使”，“縱使”之意，含有一種假設(shè)。 這兩個(gè)復(fù)合連詞的意思基本相同。它們常互換使用，但意義有細(xì)微差別。even if引導(dǎo)的讓步從句含有強(qiáng)烈的假定性，可用來表示與事實(shí)相反的假設(shè)，但不能用來描述已經(jīng)發(fā)生的事實(shí)。而even though引導(dǎo)讓步狀語從句時(shí)，是以從句的內(nèi)容為先決條件的，即說話人肯定了從句的事實(shí)，表示已經(jīng)發(fā)生了的事。例如： Well make a trip even if/though the weather is bad. 即使天氣不好，我們也要作一次旅行。 Even if he is poor, she loves him. (=He may be poor, yet she loves him.)即使他很窮，但她還是愛他。 Even though he is poor, she loves him. (=He is poor, yet she loves him.)盡管他很窮，但她還是愛她。 （4）whether.or.表示“不論是否”，“不管是還是”之意。 由這一個(gè)復(fù)合連詞引導(dǎo)的讓步狀語從句旨在說明正反兩方面的可能性都不會(huì)影響主句的意向或結(jié)果。例如： Youll have to attend the ceremony whether youre free or busy. 不管你忙不忙，都要參加這個(gè)典禮。 Whether you believe it or not, its true.無論你是否相信，這都是真的。 （5）“no matter+疑問詞”或“疑問詞-ever”的含義為“都；不管都” 它們引導(dǎo)的讓步狀語從句可以互換。例如： No matter what happened, he would not mind. (=Whatever happened, he would not mind.)無論發(fā)生了什么，他都不會(huì)介意的。 No matter who you are, you must keep the law.(=Whoever you are, you must keep the law.不管你是誰，你都要遵紀(jì)守法。 但“no matter+疑問詞”結(jié)構(gòu)只能引導(dǎo)讓步狀語從句，而“疑問詞-ever”還可以引導(dǎo)名詞性從句。例如： Whatever (=No matter what) you say, I wont believe you. (Whatever 引導(dǎo)讓步狀語從句)無論你說什么，我都不會(huì)相信你。 Ill eat whatever (no matter what) you give me. (whatever引導(dǎo)賓語從句)你給我吃什么，我就吃什么。 Whoever comes will be welcome. (Whoever 引導(dǎo)主語從句) 不管誰來都受到歡迎。2. 條件狀語從句由連接詞if或unless引導(dǎo)的狀語從句叫做條件狀語從句。在英文中，條件是指某一件事情實(shí)現(xiàn)之后（狀語從句中的動(dòng)作），其它事情（主句中的動(dòng)作）才能發(fā)生，通常譯作“假如”。（注意：在含有條件狀語從句的復(fù)合句中，表示將來時(shí)態(tài)，主句是一般將來時(shí)態(tài)，從句要用一般現(xiàn)在時(shí)主將從現(xiàn)原則，并且，切記緊跟著if的那句話是從句。）引導(dǎo)條件狀語從句的連詞有：if（如果），unless（除非；如果不），as long as（除非；只要）等。As long as youre happy, it doesnt matter what you do. 只要你高興，你做什么都沒有關(guān)系。Unless it rains, well go hiking.如果不下雨，我們將去遠(yuǎn)足。 【注意】由于unless具有否定意義，因此它引導(dǎo)的是個(gè)否定的條件（如果不）?？梢园阉醋魇莍fnot的同義表達(dá)手段。如： Unless he comes = If he doesnt come 如果他不來 Unless you work hard, you will fail. = If you dont work hard, you will fail. 如果你不努力工作，你會(huì)失敗的。 3. 目的狀語從句表示目的狀語的從句可以由so that, in order that等詞引導(dǎo)；目的狀語從句的謂語常含有may, might, can, could, should, would等情態(tài)動(dòng)詞。They worked very hard so that they could finish the work before supper. 他們拼命地干，想在晚飯前就把工作干完。 【注意】(1) so that引導(dǎo)的目的狀語從句，可轉(zhuǎn)換成in order that引導(dǎo)的目的狀語從句。若從句主語與主句主語一致，還可用in order to (do) 或so as (to do) 改成同義簡(jiǎn)單句。如：They worked very hard so that they could finish the work before supper. = They worked very hard in order that they could finish the work before supper. = They worked very hard in order to finish the work before supper. = They worked very hard so as to finish the work before supper. (2) so that引導(dǎo)的狀語從句也可表示結(jié)果，這時(shí)so that從句中根據(jù)句意可用或不用情態(tài)動(dòng)詞。 如： He got up very late this morning, so that he was late for school. 今天早晨他起得很晚，結(jié)果他上學(xué)遲到了。 【真題演練】1.
