1、复合句1 The old town has narrow streets and small houses_are built close to each other.(2011山东，32)Athey Bwhere Cwhat Dthat解析句意：这个古老的小镇拥有建造得彼此靠得很近的狭窄街道和小房子。考查定语从句。先行词是narrow streets and small houses，还原到从句中作主语，所以用关系代词that。A和C不能引导定语从句，B是关系副词，不能作主语。答案D2The villagers have already known_well do is to rebuild

2、 the bridge.(2011江西，26)Athis Bthat Cwhat Dwhich解析句意：村民们已经知道我们将要做的就是重建这座桥。考查名词 性 从 句 的 用 法。分 析 句 子 成 分 可 知 have already known后为宾语从句。而在该宾语从句中又含“_well do”这一主语从句，该主语从句缺少宾语，且表“事物”，故用what引导。答案C3_volleyball is her main focus,shes also great at basketball.(2011北京，29)ASince BOnce CUnless DWhile解析句意：尽管她把重点都放在

3、排球上，可她也擅长篮球。考查连词。根据句意应选择D项。这里while引导让步状语从句。答案D4It was April 29,2011_Prince William and Kate Middleton walked into the palace hall of the wedding ceremony.(2011福建，33)Athat Bwhen Csince Dbefore解析句意：2011年4月29日，英国威廉王子和凯特米德尔顿走入婚姻殿堂。考查状语从句。根据句意可知设空处引导时间状语从句，故答案为B项。本题易误选A项，认为本题考查强调句型，如选A项，需在April 29,2011前加

4、上介词on。答案B5 He had no sooner finished his speech_thestudents started cheering.(2011辽宁，29)Asince Bas Cwhen Dthan解析句意：他刚做完演讲，学生们就开始欢呼起来。考查固定句式。no sooner往往与than连用，意为：一就。故答案为D项。答案D1.只用that不用which的情况：先行词是不定代词all，few，little，much，something，nothing，anything等。All that we have to do is to practise English.我们不得

5、不做的一切是练习英语。先行词被序数词或形容词最高级所修饰时。The first letter that I get from him will be kept.我所收到的他的第一封来信将要被保存。先行词被all，any，every，each，few，little，no，some等修饰时。Ive eaten up all the food that you gave me.我已经吃光了你给我的所有食物。先行词被the only，the very，the same，the last修饰时。He is the very person that I am waiting for.他正是我在等待的人。先

6、行词既有人又有物时。They talked about persons and things that they met.他们谈论了他们遇到的人和事。若关系代词在从句中作表语，一般需用that。Mary is no longer the girl that she was.玛丽不再是过去那个女孩了。当主句是以who或which开头的特殊疑问句时，关系代词用that。Who is the man that is giving us the class?给我们上课的那个人是谁？2只用which，不用that的情况：关系代词前有介词，先行词指物时只用which。This is the college

7、 in which I am studying.这是我正在就读的大学。引导非限制性定语从句时只用which。Football，which is a very interesting game，is played all over the world.全世界都在踢足球，它是一项非常有趣的运动。【典 例】Whenever I met her，_was fairly often，she greeted me with a sweet smile.(2009山东卷)Awho Bwhich Cwhen Dthat解析考查非限制性定语从句，此处所选的关系词需指代前后整个句子，故用which。句意：无论何时

8、我遇见她，她都会一如既往地向我微笑。答案B【口诀巧记】定语从句1that which代表物，区别且听我来述；先行若是不定代，that就把which踹；先行词前有两数，就用that定无误；先行词前最高级，还用that必无疑；句中若有there be，that应把which替；先行主中作表语，避免重复从句里。2关系副词when/where/why，从中作状莫懈怠；时间用when，原因why，地点where经常在；关系副词要替换，介词加上关系代；关系代，关系代，that与who要除外；挑选介词要聪明，必看动词和先行；聪明反被聪明误，只因乱用关系副；关系副，关系副，定缺主宾它不住；它不住，它不住，关系

10、经常迟到使他的老师很生气。3当先行词被as，so，such，the same修饰时，关系代词常用as。Thats as good a place as I can find.这是我能找到的好地方。Ive never heard such stories as he tells.我从未听说过像他讲的这种故事。注意区别：This is the same pen as I used yesterday.这支钢笔和我昨天用的那支一样。(as表示同样的钢笔)This is the same pen that I used yesterday.这就是我昨天用的那支钢笔。(that意为同一支钢笔)【典 例】

11、My friend showed me around the town，_was very kind of him.(2009全国卷)Awhich Bthat Cwhere Dit解析句意：我的朋友真不错，他带我绕城转了一圈。句中was前缺少主语，排除关系副词where；it不能引导定语从句，故排除D项；that不能引导非限制性定语从句，故排除B项。关系代词which在此指代逗号前整个句子。答案Awhose是一个表示所属关系的词，在定语从句中作定语。of which可 以 代 替 whose指 物，词 序 一 般 是“名 词 of which”或“of which名词”。of whom可以代替

12、whose指人，词序是“名词of whom”。He lives in a room whose window faces south.He lives in a room the_window_of_which(或 of_which_the_window)facessouth.他住在窗户朝南的房子里。This is the scientist whose_name is known all over the country.This is the scientist the_name_of_whom is known all over the country.这就是那位全国知名的科学家。【典例

13、】A person_email account is full wont be able to send or receive any emails.(2009天津卷)Awho Bwhom Cwhose Dwhoever解析句意：一个人的电子邮件账户满了，就不能收发任何邮件了。email account前缺少定语，故用whose引导定语从句，相当于the email account of whom。答案C1.“介词关系代词”引导定语从句时，介词的宾语只能用which或whom。She still remembered the day on_which she won the prize.她仍然

14、记得她获奖的那天。The man with_whomshe entered the hall was her husband.和她一起走进大厅的那位男子是她的丈夫。2“名词/不定代词/数词of which/whom”引导的定语从句。I read some books，the_cover_of_which are old.我读了一些书，它们的封面是旧的。There are forty students in our class in all，most_of_whomare from big cities.我们班上共有40名学生，其中大多数来自大城市。【典例】Gun control is a su

15、bject_Americans have argued for a long time.(2009陕西卷)Aof which Bwith whichCabout which Dinto which解析句中先行词是Gun control，关系词在从句中作介词的宾语，介词前置，介词与从句动词构成搭配argue about sth，故选C。句意：枪支的控制是很长时间以来美国人争论的话题。答案C关系副词引导的定语从句经常可以用“介词关系代词”引导的定语从句来表示。1关系副词when指时间，在定语从句中作时间状语。I remember the day when(on which)I first met

16、her.我记得第一次遇见她的那天。2关系副词where指地点，在定语从句中作地点状语。Beijing is the place where(in which)I was born.北京是我出生的地方。3关系副词why指原因，在定语从句中作原因状语。Is this the reason why(for which)he refused our offer?这是他拒绝我们帮助的理由吗？【典例】Life is like a long race_we compete with others to go beyond ourselves.(2009重庆卷)Awhy Bwhat Cthat Dwhere解

17、析句意：生活像长跑比赛，我们与其他人竞争以超越我们自己。先行词为race，代入定语从句后为：.we compete with others to go beyond ourselves in the long race.由此可见，race在定语从句中作状语，且表示地点，故选关系副词where。答案D1.主语从句是在复合句中充当主语的从句。主语从句通常由从属连词that，whether,if和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等引导。That he suddenly fell ill made us surpri

18、sed.他突然病倒使我们挺吃惊的。What he wants to tell us is not clear.他要跟我们说什么还不清楚。Where the English evening will be held has not yet been announced.英语晚会将在哪里举行，还没有宣布。2what与that在引导主语从句时的区别。what引导主语从句时在从句中充当句子成分，如主语、宾语、表语，而that引导从句，不充当成分。What you said yesterday is right.你昨天说的是对的。(what引导主语从句，作said的宾语)That she is stil

19、l alive is a consolation.她还活着真是一件令人慰藉的事情。(that引导主语从句，不作任何成分，但不可省略)3主语从句若含有“是否”意义，其引导词只能用whether，不能用if。Whether he will be able to come tomorrow remains a question.他明天是否能来仍然是个问题。4有时为了避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。It is a shame that we should have lost such an important customer.真遗憾我们失去了一

20、位如此重要的客户。【典例】It is still under discussion_the old bus station should be replaced with a modern hotel or not.(2011重庆，22)Awhether Bwhen Cwhich Dwhere解析句意：那个旧公交车站是否应该被一家现代化宾馆所取代仍在讨论中。考查名词性从句。“It”作形式主语，“_the old bus station should be replaced with a modern hotel or not”作 真 正 的 主 语。根 据 句 意 及 题 干 中 的“or n

21、ot”可知答案为whether，“whether.or not”在名词性从句中意为：是否。答案A在复合句中充当谓语动词宾语或介词宾语的名词性从句称为宾语从句。引导宾语从句的关联词与引导主语从句、表语从句的关联词大致一样。1由关联词that引导的宾语从句。由关联词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如果从句是并列句时，第二个分句前的that不可省。He said(that)he liked rain very much and that he wouldnt use an umbrella when it was raining.他说他非常喜欢

22、下雨，下雨天他都不愿用伞。2由who,whom,which,whose,what,when,where,why,how,whoever,whatever,whichever等关联词引导的宾语从句，应注意句子语序要用陈述语序。I want to know what he has told you.我想知道他告诉了你什么。She always thinks of how she can work well.她总是在想怎样能把工作做好。3由whether或if引导的宾语从句，要保持陈述句语序。此外，whether与if在作“是否”讲时，一般可以换用，但在下列情况下一般只能用whether,不用if。

23、引导的从句作介词宾语时。Everything depends on whether we have enough money.一切要看我们是否有足够的钱。从句后有or not时。I wonder whether he will come or not.我想知道他来还是不来。后接动词不定式时。Can you tell me whether to go or to stay?你能否告诉我是去还是留？【典例】Many young people in the West are expected to leave_could be lifes most important decisionmarriag

24、ealmost entirely up to luck.(2009江苏卷)Aas Bthat Cwhich Dwhat解析考查名词性从句。句意：许多西方年轻人都把人生中最主要的决定婚姻几乎都归因为运气。what一词作从句的主语，并引导宾语从句，作动词leave的宾语。答案D在复合句中放在系动词之后，作表语的从句称为表语从句。可以接表语从句的连系动词有be,look,remain,seem等。1表语从句的引导词主要有：that(不可省略)，whether(不能换成if),what,who,which,how,why,when,where,whoever,wherever等。The reason

25、is that he missed the early bus.原因是他错过了早班车。The question is whether we can make good preparation in such a short time.问题是我们是否可以在如此短的时间内做好准备。Thats just what I want.那正是我想要的。This is where our problem lies.这就是我们的问题所在。2as if/as though,because,why引导表语从句。It looks as if it is going to rain.看上去天要下雨了。This is w

27、位语从句说明其前面名词的具体内容。同位语从句通常由that引导(that不能省略)，可用于同位语从句的名 词 有 advice,demand,doubt,fact,hope,idea,information,message,news,order,problem,promise,question,request,suggestion,truth，wish,word等。The news that we won the game is exciting.我们赢得这场比赛的消息令人激动。I have no idea when he will come back home.我不知道他什么时候回来。The

28、 thought came to him that Mary had probably fallen ill.他想到玛丽可能生病了。温馨提示：同位语从句与定语从句的区别。在限制性定语从句中，关系代词that充当主语或宾语，有实际意义，作宾语时，可省略。同位语从句中的that是连词，不充当句子成分，没有任何意义，但不可省略。The news(that)weheard on the radio was not true.(定语从句)我们在广播上听到的那个消息不是真的。The news that our football team won the match was encouraging.(同位语

29、从句)我们足球队赢得比赛的消息令人振奋。【典例】News came from the school office_WangLin had been admitted to Peking University.(2009四川卷)Awhich Bwhat Cthat Dwhere解析句中that引导了一个同位语从句来解释说明news的内容，由于把同位语从句后置了，所以很多考生因不能正确分析句子结构而错误选择了D项。答案C1.when,while和as的用法when既可引导一个持续动作，也可引导一个短暂性动作，可用于主句和从句动作同时发生或从句动作先于主句动作发生。When I lived ther

30、e,I used to go to the seashore on Sundays.我住在那里时，星期天常到海滨去。When the film ended,the people went back.电影一结束，看电影的人便回去了。while引导的动作必须是持续性的，侧重主句动作和从句动作相对比。Please dont talk so loud while others are working.别人在工作时，别高声谈话。as引导一个持续性动作，多用于主句和从句动作同时发生。John sings as he works.约翰一边工作，一边唱歌。2as soon as,immediately,the

31、 moment,the minute,no sooner.than.,hardly/scarcely.when.的用法这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一就”，从句中用一般时态代替将来时态。The moment she arrives,we can start.她一到，我们就可以开始。No sooner had we arrived at the station than the train left.我们一到车站火车就出发了。The boy burst into tears immediately he saw his mother.男孩一看到他的母

32、亲就哭了。3till,until和not.until的用法在肯定句中，主句谓语动词必须是延续性动词，意为“某动作一直延续到某点才停止”。You may stay here till/until the rain stops.你得在这里呆到雨停。在否定句中，主句谓语动词必须是非延续性动词，从句为肯定式，意为“某动作直到某时间才开始”。He wont go to bed till(until)she returns.直到她回来他才睡。not.until句型中的强调和倒装说法。It was not until you told me that I had any idea of it.(强调句型)N

33、ot until you told me did I have any idea of it.(notuntil置于句首，主句要倒装)4before和since的用法连词before表示“还未就”，“不到就”，“才”，“趁还没来得及时”。Before they reached the station,the train had gone.他们(还没)到火车站前，火车已经开走了。We hadnt run a mile before he felt tired.我们跑了还不到一英里他就累了。Please write it down before you forget it.趁你现在没忘把它记下来。

35、e he lived here.他不在这儿住已经有三年了。5every time,each time,next time,the first time,any time,all the time的用法这些短语用来引导时间状语，表示“每当”，“每次；下次”等。Every time I meet her I always forget her name.每次我见到她时，我总忘了她的名字。Next time you come,do remember to bring your son here.下次你来时，记住把你的儿子带来。You are welcome to come back any time

36、 you want to.你想回来随时可以回来。【典 例】Peter was so excited_he received an invitation from his friend to visit Chongqing.(2009重庆卷)Awhere Bthat Cwhy Dwhen解析考查时间状语从句。句意：当他收到朋友参观重庆的邀请时，Peter很高兴。根据句意可知，此题应填when引导时间状语从句。答案D【口诀巧记】常用状语从句状语从句三要点，时间、原因和条件。从句如果表时间，when，after，before走在前。状语从句表原因，because前面来引导。状语从句表条件，if前面来

37、引导。主句通常前面走，从句紧紧跟在后。从句如在主句前，从句之后加逗点。地点状语从句：1 地 点 状 语 从 句 可 用 where,wherever,anywhere,everywhere等引导。地点状语从句可用于主句之前或之后。You are free to go wherever you like.你愿意去哪里就去哪里。Where there is a will,there is a way.有志者事竟成。Wherever there is smoke,there is a fire.无火不生烟(既无风不起浪)。2注意区分引导的定语从句与状语从句。Youd better make a ma

51、her BalthoughCfor Dso解析句意：尽管我费了好大周折才把Frank弄醒，他却坚持说自己没有睡着。考查状语从句。用though/although引导让步状语从句，表示“尽管，虽然”。A项是否；C项引导原因状语从句，D项引导并列句，表示“因此”，都不符合句意。答案B【典 例 1】Animals suffered at the hands of Man_they were destroyed by people to make way for agricultural land to provide food for more people.Ain which Bfor which

52、Cso that Din that错因分析根据句意，选D。考生很容易受思维定式影响，首先将选项D排除，认为英语中的介词in是不能与that连用的，进而做出了错误的选择。归纳总结在英语中，that能否与介词in连用是有条件限制的。在定语从句中，that为 关 系 代 词，不 能 与 in等 介 词 连 用。而 在 此 题 中 in that这个结构被称为复合从属连词，意为“因为”，引导原因状语从句，与because用法相近，后接从句。【典 例 2】I saw a woman running toward me in the dark.Before I could recognize who sh

53、e was,she had run back in the direction_she had come.Aof which Bby whichCin which Dfrom which错因分析考查“介词关系代词”形式的定语从句。考生易受思维定式的影响认为本题中的先行词为direction，通常与介词in搭配，表示“朝方向”，进而误选C。归纳总结考生在做题时一定要注意，所选择的答案不但要符合语法规则，而且还要符合句意和逻辑。句意：在黑暗中我看到一名女子向我跑来。还没有等我看清楚她是谁，她就沿着原来的方向跑回去了。根据句意可知，应用介词from。故选D。【典例】_was most importa

54、nt to her,she told me,was her family.AIt BThis CWhat DAs错因分析考生很容易误选D项，即认为是考查as引导位于句首的非限制性定语从句。归纳总结句中的she told me是插入成分，将其去掉后，可以看出“_was most important to her”是一个主语从句，在句中作主语，谓语动词为was，表语为her family。该主语从句缺少主语，因为it,this和as均不能引导名词性从句，故选项A、B和D均被排除。【典例1】The lawyer seldom wears anything other than a suit_the

55、season.Awhatever Bwherever Cwhenever Dhowever【典例2】_hungry I am,I never seem to be able to finish off this loaf of bread.AWhatever BWheneverCWherever DHowever错因分析对whatever与however引导的让步状语从句中的引导词的考查是历年高考中的常考点，考生因弄不清其区别常选错。归纳总结whatever与however的用法区别与感叹句中的what与how的区别类似。在让步状语从句中，引导词whatever修饰的中心词为名词，通常其后直接

56、接名词；而引导词however修饰的中心词为形容词或副词，通常其后直接接形容词或副词。故典例1应选择whatever，相当于no matter what，其后用陈述语序，其完整形式为.whatever the season is。典 例 2应 选 择 however，相 当 于 no matter how，其后用陈述语序。【典例1】Occasions are quite rare_I have the time to spend a day with my kids.Awho Bwhich Cwhy Dwhen错因分析考 查 定 语 从 句 中 关 系 词。先 行 词 为“occasions”

57、，意为“机会”。由于空格后的句子不缺少成分，故应填关系副词when，在定语从句中作状语，相当于on which，故选D。归纳总结英语中，为了避免“头重脚轻”现象(即避免主语过长)出现，常用it作形式主语、形式宾语或将主语中的从句置于句尾以平衡句子。【典例2】A warm thought suddenly came to me_Imight use the pocket money to buy some flowers for my mothers birthday.Aif Bwhen Cthat Dwhich错因分析选C。考生很容易误选A项或B项，认为应用when或if引导从句。但在本题中w

58、hen或if引导时间状语从句或条件状语从句，虽然在语法结构上是成立的，但在逻辑上是不成立的。归纳总结空 格 处 引 导 的 从 句 是 一 个 被 suddenly came to me分隔开的同位语从句，对thought进行解释说明。为了避免“头重脚轻”现象，将从句置于句尾。由于空格后边的句子是一个成分不缺、意思完整的句子，故用只起连接作用而没有任何含义的连接词that引导。【典例】The growing speed of a plant is influenced by a number of factors，_ are beyond our control.Amost of them B

59、most of whichCmost of what Dmost of that错因分析考查非限定性定语从句。考生很容易把它与并列句弄混，误选A项。由于在定语从句中关系代词that不能直接位于介词后；what不能用于定语从句，故选项C和D可以被排除。归纳总结判断句子是定语从句还是并列句，关键在于看题干中的横线前是否有并列连词and等，如果有，为并列句，那么A项为正确答案；反之B项为正确答案。本题中，由于无并列连词，故选B。【典例1】_，his idea was accepted by all the people at the meeting.AStrange as might it soun

60、dBAs it might sound strangeCAs strange it might soundDStrange as it might sound【典例2】_，he never seems able to do the work beautifully.ATry as he does BAs he triesCTry as does he DAs he does by【典例3】_，he talks a lot about his favorite singers after class.AA quiet student as he may beBQuiet student as h

61、e may beCBe a quiel student as he mayDQuiet as he may be a student错因分析这几个题均是对as在异常语序中用法的考查，是高考英语试题中的中难度题，应引起考生的高度重视。归纳总结1D2.A3.Bas用于异常语序结构时，表示让步关系，意为“尽管”，通常用于以下几种结构：(1)adj./adv.as主语谓语。Much as I have traveled,I have never seen anyone whos as capable as John.虽然我已经去过很多地方，但我从未见过像约翰这么能干的人。Hard as he trie

62、d,he didnt pass the driving test.虽然他很努力，但他没有能够通过驾驶员考试。(2)可数名词单数as主语谓语。Child as he is,he knows a lot.尽管他还是一个孩子，但他却懂很多。(3)实义动词as主语助动词(do的适当形式)或情态动词。Try as he might,he never succeeds.尽管他很努力，但从未成功过。这种结构可以转换为由though或although引导的正常语序的让步状语从句。【典 例】_is reported in the newspapers,talks between the two countrie

63、s are making progress.AIt BAs CThat DWhat错因分析本题是一道特别经典的试题，经过不同的变形，四个选项都有可能成为答案，因而考生极易出错。本题选择B项，as引导位于句首的非限定性定语从句，指代“talks.progress”这句话的内容。归纳总结(1)若将原题改为：_is reported in the newspapers that talks between the two countries are making progress.那么答案为A项。“It”在句中作形式主语，指代that从句，以避免出现“头重脚轻”现象。(2)若将原题改为：_is re

64、ported in the newspapers is that talks between the two countries are making progress.那 么 答 案 为 D项。“What.newspapers”是一个主语从句，在句中作主语；句子的谓语动词为is，题中的“that.progress”是一个表语从句。(3)若 将 原 题 改 为：_talks between the two countries are making progress is reported in the newspapers.那么，此时的答案为C项。此时“That.progress”是一个主语从句，在句中作主语。
