  典型考题例析
  1.(2007包头市)-Who willteach youto SWim this
  summer?
  -The twins.Because_____Lily_____Lu-
  cy SWim very well.
  A.both:and B.neither;nor
  C.either;or D.not only.but also
  点拨:both…and…连接主语时,谓语动词用复数形式。答案为:A。
  2.(2007兰州市)James with the Greens
  the White Tower Park if it_____tomorrow.
  A.are going to;isn’t rainy
  B.are going to;doesn’t rain
  C.is going to;won’t rain
  D.is going to;isn’t rainy
  点拨:本句的主语为James,with the Greens是介词短语,因此第一空谓语动词应用单数形式;第二空是条件状语从句.应用一般现在时表示将来。答案为:D。
  3.(2007山西省)It rained heavily this morning,but
  _____of my classmates were late for sch001.
  A.neither B.none C.all
  点拨:根据but,应先排除C;“neither(两者)of 名词复数”作主语时,谓语动词要用单数形式;“none of 名词复数(三者或三者以上)”谓语动词可用单数或复数。答案为:B。
  4.(2007陕西省)Trees and flowers_____every
  year to make our country more beautiful.
  A.is planted B.was planted
  C.are planted D.were planted
  点拨:and连接的两个主语时,意义上表示复数,谓语动词通常用复数形式。答案为:C。
  5.(2007临沂市)Not only Jim but also his sister_____a few cities in the SOUth since they came to China.
  A.will visit B has visited
  C.have visited D.visited
  点拨:由并列连词not only…but also…,ei-ther…or…,neither…nor…等连接两个主语时,谓语动词的单复数形式一般采取就近原则。另根据since they came to China,主句中的谓语动词应用现在完成时。答案为:B。
  6.(2007济宁市)In the coming summer h01idays,my
  family_____going to take a one-week trip to
  Qingdao.
  A.is B.are C.was D.were
  点拨:集合名词family,此处强调其中的每个成员,谓语动词用复数形式。答案为:B。
  
  误区警示
  Everyone except BiU and Jim_____therewhen the meeting begaru
  A.was B.is C.are D.were
  
  同学们认为Bill and Jim是复数形式,所以后面用复数形式vv’ere。其实本句的主语是everyone,主语后面的except Bill and Jim是介词短语。介词with,together,like,but,except,besides等构成的介词短语放在主语后面时,其谓语动词的数不受影响,即主语是单数,谓语动词就用单数,主语是复数,谓语动词也用复数。本题答案为A。在解主谓一致的题目时,关键是要注意其有关原则,掌握常见的主谓一致的形式。

  二、从题后括号内选择正确的词填空。
  
  一、过“引导词关”
  宾语从句的引导词通常分为三个类型。
  1.当宾语从句由陈述句变化而来时,用that引导从句,其中that无具体意义,在口语或非正式文体中常省略。如:He said,“Simon will visit the GreatWall tomorrow”-He said(that)Simon would visitthe Great Wall the next day.
  2.当宾语从句由一般疑问句变化而来时,用if或whether引导从句,意为“是否”。如:Sally asks,“Does Chen Huan miss her parents?”-Sally asks if/whether Chen Huan misses her parents.
  whether与if用法的对比:
  whether和if引导宾语从句时,可以互换使用。如:I don’t know whether/if she will come.我不知道她是否会来。
  在“be+形容词”之后,用whether或if均可。如:1 was not sure whether/if he would come to attendthe meeting.我不能肯定他是不是会来参加会议。
  但在下列情况下只能用whether,不能用 if:
  (1)引导表语从句或同位语从句。如:The ques-tion is whether the lecture is worth listening to.问题是这报告是否值得听。
  (2)在句首引导主语从句。如:Whether this istrue or not,I can’t say.这是不是真的,我说不准。
  (3)whether后可以直接跟不定式,if则不能。如:She hasn’t decided whether to go or not.她还没有决定去还是不去。
  (4)在介词之后只能用whether,不能用if口如:Everything depends on whether we have enough mon-ey.一切取决于我们是否有足够的钱。
  (5)whether后面能紧跟or not,if则不能。如:Idon’t know whether or not they will come for ourhelp.我不知道他们是否来帮助我们。
  3.当宾语从句由特殊疑问句变化而来时,则用连接代词who/whose/what/which或连接副词when/where/why/hOW等引导。它们在从句中都充当一定的句子成分,不可省略。如:Lingling wantedto know.When will the meeting begin?-Lingling wanted to know when the meeting would begin.
  二、过“语序关”
  在含有宾语从句的复合句中,充当宾语从句的句子不管原来是什么语序,在从句中都用陈述句语序,即:“引导词 主语 谓语 其他”结构。如:Tom Said.I have had the MP4 for a year.(从句为陈述句)-Tom said he had had the MP4 for a year.
  Sally asked.Is the boy a student?(从句为一般疑问句)一Sally asked if/whether the boy was a student.
  Chen Huan wanted to know.Where is the post office?(从句为特殊疑问句)-Chen Huan wanted to know where the post office was.
  注意:当who在从句中作主语时,语序本来就是“主语 谓语”,所以就不再变了。如:The teacher asked.Who is the first to come here?-The teacher asked who was the first t0 come here.
  三、过“时态关”
  宾语从句的时态,要受到主句时态的限制,即要与主句时态呼应。含有宾语从句的主从复合句在时态呼应上要遵循以下三条规则:
  1.当主句的时态是一般现在时、一般将来时、祈使句时,从句的时态可根据意义的需要而选用任意一种。如:
  Do you know who lost a Walkman yesterday?
  Please tell me why he hasn’t come yet.
  Will you show me how you worked out the
  maths problem?
  2.若主句的时态为一般过去时,宾语从句须用相对应的过去的某一种时态。这种时态的对应主要包括:一般现在时——一般过去时;一般将来时——过去将来时;一般过去时——过去完成时;现在进行时——过去进行时;现在完成时——过去完成时。如:
  Mr Zhang said.I am a teache-Mr Zhang said(that)he was a teacher.
  We asked him.What are you doing?——We asked him what he was doing.
  I asked your secretary if she could come.
  3.当宾语从句所叙述的是客观事实、真理、自然现象、名言警句、谚语等时,不管主句是什么时态,从句一律用一般现在时。如:Our teacher told us light travels faster than sound.
  四、宾语从旬的简化
  1.当主句的谓语动词是hope,agree,wish,choose,decide,promise等,后面带宾语从句,且主从句主语相同时,可以简化成不定式结构作宾语。如:I hope that I shall see you soon.-I hope to see you soon.
  2.当主句谓语动词是decide,wonder,know,learn,forget,remember等词时,后面带的宾语从句可简化成“疑问词 不定式”结构,此时,主从句主语也须一致。如:I don’t know what I should do next.-I don’t know what to d0 next.
  She hasn’t decided whether she should go or not.-She hasn’t decided whether to go or not.
  3.当主句谓语动词是ask,tell,show,teach等,后带双宾语,且从句主语和间接宾语一致时,宾语从句可转化成“疑问词 不定式”结构。如:
  Would you please tell me how l can get to the cinema?-Would you please tell me how to get tothe cinema?
  Please tell me where I can find her.-Please tell me where to find her.
  但是,如果间接宾语和从句的主语不一致。一般不要把宾语从句简化,否则会产生歧义。如:
  She didn’t tell me where she would go.-She didn’t tell me where to go.简化的句子含义有以下两种:“她没有告诉我她要去什么地方。”或“她没有告诉我我要去什么地方。”
  4.当主句的谓语动词是order(命令),require(需要)等时,如果主句和从句的主语不一致,宾语从句可转化成“名词(:代词) 不定式”结构。如:The teacher ordered that we should go at once.-The teacher or-dered us to gO at once.
  5.除了以上用不定式简化宾语从句之外,也可以采用另外一些结构。如:Tom insisted that he should g0 with us.-Tom insisted on going with us.

  -OK。her name is Ciei.
  A.what was her name
  B.what her namewas
  C.what ls her name
  D.what her name is
  点拨:主句WOUld you please teU me是一种客气委婉的说法,不要把它看作是过去时态;在宾语从句中要用陈述句的语序。答案为:D。
  2.(2007山西省)-Did you know______at the bus stop?
  -Maybe their teacher.
  A.who are they waiting for

  C.comes;comes
  D.will come;comes
  点拨:本题考查if引导的宾语从句和条件状语从句的区别:if(是否)引导宾语从句时,按具体情况来定所需的时态。if(如果)引导状语从句时,要用一般现在时表示将来。答案:D。
  4.(2007潍坊市)Our physics teacher told us light______faster than sound last term.
  A.travels B.travel
  C.travelled D.travellir培
  点拨:宾语从句表示的是客观事实,无论主句时态如何,宾语从句中都应用一般现在时。答案为:A。
  
  误区警示
  宾语从句是中考考查的重点,重点考查宾语从句的引导词、语序和时态。在中考阅卷中发现许多同学在时态的运用上及语序的运用上常常发生错误,请同 学们要特别注意上文所讲的“时态关”和“语序关”。

  第三节 状语从句
  
  要点归纳
  状语从句在复合句中作状语,修饰主句中的动词、形容词或副词等。状语从句放在主句之前时,常用逗号分开,放在主句之后一般不用逗号。状语从句按其意义和作用可以分为时间、条件、原因、结果、目的、让步、比较等。
  1.时间状语从句
  (1)时间状语从句一般不用将来时,如果主句是一般将来时、祈使句或含有将来的意味,when,assoon as,till/until等引导的时间状语从句用一般现在时代替一般将来时。如:We’ll have to clean the plates before Mother comes home.
  (2)when’as,while都表示“当……的时候”,但when引导的时间状语从句的动作和主句的动作可以是同时发生,也可以先后发生;while既可指时间点,也可指时间段;用as,while时则强调主句和从句的动作同时发生;但while只能表示一段时间,从句须用延续性动词。如:He is listening to the music whileshe is washing clothes.
  (3)till和until都表示“直到……为止”,主句用延续性动词,主句和从句都用肯定式;表示“直到……才”时,主句用终止性动词,从句用肯定式。主句用否定式。until较till正式,until引导的时间从句可以放在句首。如:
  She won’t go away till you promise to help her.
  Until you told me.I had heard 0f nothing about what happened.
  (4)since引导的时间状语从句常用一般过去时,其主句一般使用现在完成时。如:Jim has been in thefactory for two years since he left school.
  2.条件状语从句
  条件状语从句由if(如果),as long as(只要)等引导。如果主句是将来时,条件状语从句用一般现在时。如:The students will go to the Summer Palace if it doesn’t rain tomorrow.
  3.原因状语从句
  原因状语从句由because(因为),as(由于),since(既然,由于)等引导。because(因为)不能和so(所以)用在同一个句子中。如:-Is David at school to-day?-No.He is at home because he has a bad cold.
  4.结果状语从句
  结果状语从句一般由so…that…(如此……以至……),such…that…(如此……以至……)等引导。从句常用can,could等情态动词。如:He hurt her so badly that she had to see a doctor.
  so…that…与such…that…的区别是:so后跟形容词或副词,such后跟名词。如:
  It rained so heavily that nobody could walk out-side.
  She is such a lovely girl that people like her very much.
  so…that…引导的状语从句如果是否定意义,可以变为too…to…结构的简单句。如:
  It’s so heavy that we can’t move it.-It’s too heavy for us to move.
  5.目的状语从句
  目的状语从句常由so that(为了,以便),in order that等引导,放在主句之后,从句中常用can,could,may,might等动词,in order that引导的从句可以放在主句前。如:
  If you do know。answer in a loud enough voice so that all the class may hear you.如果你知道(答案),就用足够大的声音来回答,以便全班同学都能听得见。
  We stopped at Hangzhou so that we might go tothe West Lake.我们在杭州停了下来,以便能去看看西湖。
  In order that every student might understand it.the teacher explained that passage again and agaim为了让每个学生都能明白,老师把那一节解释了一遍又一遍。
  so that引导的目的状语从句可转换成动词不定式短语。如:-She hurried to sch001 s0 that shemight not be 1ate.-She hurried t0 sch001 in 0rder notto be late.
  6.让步状语从句
  让步状语从句由although,though(虽然,尽管),as(虽然,尽管)等引导。如:He’s good at volleyballthough he isn’t talI enough.
  as引导让步状语从句时,常用倒装语序,倒装的成分常是形容词、名词、分词、副词或动词。若倒装的是单数名词时,其前不加冠词。如:
  C1ever as he is,he doesn’t study well.
  Hard as I tried,1 was unable to make much pro—gress.
  Child as he is.he knows a great deal.
  注意:although/though(虽然)不能与but(但是)用在同一个句子中,两者只能选其一。
  7.比较状语从句
  比较状语从句由than(比)as…as…(和……一样),not as/s0…as…(和……不一样)等连词引导。如:
  I know you better than he does.
  This story is as interesting as that one(is).
  
  典型考题例析
  1.(2007兰州市)My brother is going to look for an-other job________the company offers him more money.
  A.after B.when
  C.unless D.besides
  点拨:根据题干意义“我的哥哥将去寻找另一份工作,(除非)公司给他更多的钱”,应该用unIess。答案为:C。
  2.(2007贵阳市)If Betty has time,she________
  climbing with parents tomorrow.
  A.goes to B.will go C.doesn’t go
  点拨:观察题干,可知本题是考查if条件状语从句 主句结构,条件状语从句中用了一般现在时,表示将来,主句应用一般将来时。答案为:B。
  3.(2007贵阳市)Kate is________busy________ she can’t lmve a picnic、with us this weekend.
  A.so…that B.too…to C.so…as
  点拨:题干意义为“凯特是如此的忙以至本周末她不能和我们一起野餐”。答案为:A。
  4.(2007山西省)She still failed the exam,________she tried her best.
  A.though B.because C.if
  点拨:由题意可知句子前后意思构成转折关系,因此应用从属连词though引导让步状语从句。答案为:A。
  5.(2007陕西省)We have been good friends________we joined the same Pipg-pong team.
  A.after B.befOre
  C.since D.until
  点拨:由于主句的时态是现在完成时,从句中的时态是一般过去时,因此应选用since。答案为:C。
  6.(2007河北省)I didn’t know he came back________I met him in the street.
  A.since B.when C.until D.after
  点拨:根据题干意义“直到我在街上遇见了他,我才知道他回来了。”可知本题是not…until…结构。答案为:C。
  
  误区警示
  I don’t know when________.When he________,I’11 call you.
  A.will he come;will come   B.he will come;comes
  C.he comes;wm come
  D.does he come;comes
  我们知道,when作“什么时候”讲,可以引导宾语从句,when作“当……时候”讲,可以引导时间状语从句。有些同学不能正确地分清这两种从句,结果造成错误。本题的第一句“I don’t knOW when he wiUcome”是含有宾语从句的复合句,从句根据需要用一般将来时;“when he comes back,I’ll can you.”是包含时间状语从句的复合句,在时间状语从句中,要用一般现在时表示将来。所以本题答案为B。

  第四节 定语从句
  
  要点归纳
  在复合句中,修饰某一名词或代词的句子(从句)叫定语从句。定语从句所修饰的词叫先行词。定语从句作定语时,位置在先行词的后面。
  引导定语从句的词有关系代词that,which,who(宾格whom,所有格whose)和关系副词when,where,why等。关系代词或关系副词在先行词和定语从句之间,起联系作用,同时又作定语从句的一个成分。
  一、关系代词的用法
  1.that指物,有时也指人,在定词从句中作主语或宾语。作主语时不可省略,作宾语时可省略。如:
  His father works in a factory that makes TVsets.他父亲在一家制造电视的工厂工作。(作主语,指物,不可省略)
  The coat(that)I put on the desk is blue.我放在这张课桌上的外衣是蓝色的。(作宾语,可省略)
  2.which指物,不指人,在从句中作主语或宾语。作主语时不可省略,作宾语时可省略。如:
  Who was hurt in the accident which happenedyesterday?谁在昨天的事故中受伤了?(指物,作主语,不可省略)
  The film(which)we saw last night was wonder-ful.我们昨天看的那部电影很精彩。(指物,作宾语,可省略)
  注意:
  which与that指物时可互相代替,但that比which更常见,尤其是在口语中。但要注意that可用来指人,而which则不能指人。如:The girl which of-ten helps me with my English is from America.(×)The girl that often helps me with my English is fron America.(√)
  3.who指人,在从句中作主语或宾语。作主语时不可省略,作宾时可省略。如:
  The teacher who spoke at the meeting just nov is having a rest in his office.刚才在会上讲话的那位教师正在他的办公室休息。(作主语,不可省略)
  He know the writer(who)we met yesterday.催认识昨天我们见到的那位作家。(作宾语,可省略)
  4.whom指人,为who的宾格形式,在定语从句中只作宾语,其前没有介词时可用who替代使用,也可省略。如:
  Who is the man(whom/who/that)Xiao Wang istalking to?正:在与小王谈话的男人是谁?(作宾语,可省略)
  The doctor with whom he went to the Australialast month is very famous.上个月与他一起去澳大利亚的那位医生是非常有名的。(作宾语,介词with提到了whom之前,whom在这里不可省略,也不可用who替代)
  5.whose指人或物,在从句中作定语。指物时常可用ofwhich取代。如:
  The building whose roof we can see from here is a hotel.在我们这儿望得见房顶的那座房子是一家旅馆。
  The boss in whose department Mr King workedhad heard about the accident.金先生工作的那个部门老板已听说了这起事故。
  注意:
  在定语从句中常有介词。当介词放在从句末时,who/that/which仍然可省略。但,把介词提到关系代词前,只能用介词 which/whom结构,这时which也不能用that来代替。如:The room(that/which)Ilive in is very clean.我住的房间很干净。
  -The room in which I live is very clean.(不可用that)
  -The room where I live is very clean.(where-in which)
  只能用that不能用which引导的定语从句:
  1.定语从句所修饰的先行词被形容词最高级所修饰时,只能用that引导。如:It is the most interest-ing novel(that)I have ever read.这是我曾经读过的最有趣的小说。
  2.定语从句所修饰的先行词被序数词所修饰时,只能用that引导。如:The boys like the second les-son that is about“The football match".男孩们喜欢第二课,第二课是关于足球赛的。
  3.定语从句所修饰的先行词被the only,the very或the same所修饰时,只能用that引导定语从句。如:Where is the very book(that)I bought just now?我刚才买的那本书在哪儿?
  4.定语从句所修饰的先行词被不定代词如:all,any,no,every,little,a或much,many等修饰时,只能用that引导。如:Here is a11 the money(that)my fa- ther has.这是我父亲所有的钱。
  5.定语从句所修饰的先行词为everything,something。anything’all,none,much,little,few等不定代词时,只能用that引导。如:I want everything(that)I want.我想要我所需要的一切东西。
  6.定语从句所修饰的先行词中同时含有“人”和“物”的名词,只能用that引导。如:I can still remem-ber the persons and some pictures(that)I see in theroom.我仍能记得我在那个房间所见到的人和一些画。
  注意:
  the same…that表示同一个人或物,that只起加强相同语气的作用,即便省去也不改变句意,名词前的Salne也可省略。而the same…as中的same和as则不能省略,只表示“……与……一模一样”而不一定是同一个人或物。
  比较:I want to buy the same book that youbought.我想买与你买的相同的书。(想买你买的那本书)=I want to buy the book you bought.
  I want to buy the same book as you bought.我想要买和你买的一样的书。(不是买你的那本书)
  二、关系副词的用法
  1.when指时间,在定语从句中作时间状语。如:
  I still remember the day when I first came to theGreat Wall.我还记得我第一次来长城的那天。
  Do you still remember one afternoon ten yearsago when I came to your house and borrowed a dia-mond necklace?你记得十年前的一天下午,我来到了你家并借了一条钻石项链吗?
  注意:
  在比较正式的语体中,when可以根据不同的先行词分别由介词短语at/on/during which取代。如:Idon’t remember the day when/on which he left.我记不得他离开的日子。
  2.where指地点,在定语从句中作地点状语。如:He used to work hard on the small farm wherethey lived.他经常在他们所住的小农场辛勤劳动。
  where也可根据不同的先行词分别由介词短语at/in/from which等取代。如:This is the housewhere we lived five years ago.这是我们五年前住过的房子。=This is the house in which we lived fiveyears ago.=This is the house(which/that)we livedin five years ago.
  3.why指原因,相当于for which,在定语从句中作原因状语。如:That’s the reason why/for whichshe spoke.那就是她发言的原因。

  误区警示
  
  在阅卷中发现相当多的同学对定语从句中关系词的用法不清楚,尤其对关系代词whose的用法没有把握,如:Do you know Mr Black________daughteris a famous musician?
  A.that her B.whose
  C.who D.ofwhom
  有的同学认为先行词Mr Black是指人,所以想到答案C或D,其实无论先行词是人还是物,如果后面紧跟一个名词,应该用whose作定语。答案为:B。

  第五节 虚拟语气
  
  要点归纳
  虚拟语气常用来表示所说的话与事实相反或实现的可能性很小,也可表示说话人的主观愿望、假设、猜测或建议。
  一、虚拟语气在条件句和主句中的用法
  我们目前主要掌握与现在、过去或将来事实相反的虚拟条件句。
  1.表示与现在事实相反的情况。其结构为:从句(If 主语 动词的过去式),主句(主语 should/would/could 动词原形)。如:If 1 were you,1 wouldtake a small present.如果我是你的话,我就带上一件小礼物。
  If I won a million dollars.1 would travel around the world.如果我赢了一百万美元,我要周游世界。
  2.表示与过去事实相反的情况。其结构为:从句(If 主语 had 过去分词),主句(主语 should/would have 过去分词)。如:If you had been careful,you would not have broken it.你要是当心点,就不会把它打破了。(事实是:你没有当心,东西被打破了)
  在虚拟条件句中,be动词不论什么人称,都用were。如:If she were not so busy。she would come here with me.要是她不这么忙,就和我一起来了。
  3.表示与将来事实相反的情况。其句子结构为:从句(If 主语 动词的过去式/should 动词原形/were t0 动词原形),主句(主语 would/should/could 动词原形)。如:
  If he came tomorrow.would you welcome him?假如他明天来,你欢迎他吗?(事实是:明天他不可能来)
  If it should rain this afternoon.what would you do?假如今天下午有雨,你怎么办?
  Ifit were to rain tomorrow,I should stay at home.如果明天下雨,我就呆在家里。
  二、虚拟语气在宾语从句中的用法
  在动词wish后的宾语从句中,表示与现在或过去的事实相反,或表示对将来的主观愿望,从句通常省略连词that。
  1.表示对现在情况的虚拟:从句动词用过去式或过去进行式(be的过去式用were)表示。如:
  I wish I knew the answer to the question.我希望我知道这个问题的答案。(可惜不知道)
  I wish it were spring in my hometown all theyear around.但愿我的家乡四季如春。(只是愿望,实际根本不可能实现)
  2.表示对过去情况的虚拟:从句动词用had 过去分词。如:
  I wish(that)I hadn’t wasted so much time.我后悔不该浪费这么多时间。(实际上已经浪费掉了)
  He wishes(wished)he hadn’t lost the chance.他真希望没有失去机会。(事实上机会已经失去了,他感到惋惜)
  3.表示对将来的主观愿望:谓语动词形式为would/should/could/might 动词原形,此时要注意,主句的主语与从句的主语不能相同,因为主句的主语所期望的从句动作能否实现.取决于从句主语的态度或意愿(非动作名词除外)。如:
  I wish it would stop raining.但愿雨能停止。
  I wish you would be quiet.我希望你安静一些。
  
  误区警示
  有许多同学对hope和wish的用法经常混淆不清,常写出类似下面错误的句子:I wish I can fly to the moon one day.wish后接的宾语从句表示的愿望实现的可能性很小,因此要用虚拟语气形式:i wish i could fly to the moon one day.
  hope 宾语从句(陈述语气)表示的是可能实现的愿望。如:
  I hope it is true.(有可能是真的)
  I wish it were true.(不可能是真的)
  要避免发生类似的错误,同学们要注意掌握陈述语气与虚拟语气的区别及虚拟语气的各种形式。
