11、也无词汇意义，eg.He knew that he should work hard.表二：宾语从句 一、宾语从句的连接词 在口语中常被省略。2.连词 if、whether，它们起连接作用，在从句中不作句子成分，作是否解，在口语中多用 if。一般情况下，if 和 whether 可以互换，但以下 3 种情况只能用 whether：a.在不定式前：Whether to go there or not hasnt been decided.b.在介词前：It depends on依靠 whether it is going to rain.c.与 or not 连用：They are talkin

13、e to see Can you tell me who we have to see The teacher asked the students what they were doing.述句变为宾语从句时,要注意人称和时态的变化,语序不变。eg.She said,I will leave a message on the desk.She said she would leave a message on the desk.一般疑问句和特殊疑问句变为宾语从句时,也要注意人称和时态的变化,后面接述语序。Eg.Where are the tickets I asked him.I asked

14、 him where the tickets are.三、时态照应。如果主句谓语是一般现在时或将来时，从句谓语的时态不受限制；如果主句谓语的时态是一般过去时，从句一般要随着改为相应的过去时态一般过去时、过去进展时、过去将来时、过去完成时 eg.I thought that you are free today.I thought that you would be free today.【注意】当宾语从句表达的是客观真理时，不管主句谓语的时态如何，从句都用一般现在时。eg.The teacher told us that the earth moves around the sun.四、注意宾

15、1.宾语从句一般用述语气，但是，当主句的谓语动词为advise,insist(坚决主),suggest(建议),require,request,order,ask(要求)等表示请求、命令、要求、主she insisted that he(should)go there with her.她坚决要求他跟她一起去那儿。The doctor suggested that she(should)take more e*ercise every day.表二：宾语从句 语从句的语气 意义的动词时，从句谓语要用虚拟语气，即用should+动词原形(should 往往可以省略)。医生建议她每天多进展锻炼。2

16、.但当 insist 表示坚持说，suggest 表示暗示、说明，ask 表示问时，宾语从句用述语气 He insisted that he didnt steal her watch.他坚持说他没有偷她的手表。His smile suggested that he did well in the interview.他的微笑说明他面试得很好。3.动词 wish 后的宾语从句也要用虚拟语气，即从句谓语用过去式(针对现在情况而言)、过去完成时(针对过去情况而言)或用would/should/could/might+动词原形(针对将来情况而言)。I wish I were a bird.我希望我是

17、一只鸟。I wish we lived on the moon now.我希望我们现在住在月亮上。五、注意宾语从句的否认问题 当否认宾语从句时，一般直接对从句的谓语动词进展否认。I know that he wont tell a lie to us.我知道他不会对我们说谎。He said he hadnt been to america before.他说他以前没有去过美国。但是，当主句的谓语动词为 think,believe,suppose,imagine 等，假设时态为一般现在时，谓语动词前又没有副词修饰时，宾语从句的否认应该转移到主句的谓语动词上。如：I dont think that

18、 he will e to help us today.我想他今天不会来帮我们的忙了。表三：表语从句 定义 在一个复合句中其表语局部是一个句子，这个当表语的句子就是表语从句。表语从句位于连系动词之后。连系动词 1.be 动词 2.感官动词 look看起来像是 smell闻起来 sound听起来 taste尝起来 feel 摸起来，给感觉 3.表变化的词 seem,似乎，好似 appear,显得，看起来好似keep,保持的状态 remain,仍是 stay保持*种状态 prove 证明是get变成，变得起来 fall进入*种状态 grow渐渐变得起来，长得 turn转变成新的与原来完全不同的色彩

20、e was late was that he missed the train.(虚线局部是定语从句)3.whether 可引导表语从句，但与之同义的 if 却通常不用于引导表语从句。4.主句的主语常常是些抽象名词，如 question(问题)，trouble(麻烦)，problem(问题)，result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由)等.(2)连 接代词 what,which,who,whom,whose 等 1.That was what she did this morning on reaching the atti

26、可省略。常见的词有：advice，suggestion,order,proposal,plan,idea 等。e.g.：My suggestion is that we(should)start early tomorrow.我的建议是我们明天一早就出发。表四：同位语从句 定义 同位语从句用于对前面的名词作进一步解释，说明名词的具体容。同位语从句一般由 that 引导，但也可以由 whether 以及连接代词和连接副词引导。常放在 fact,news,idea,truth,hope,problem,promise,doubt,thought,message,words 消息 informati

30、o.表语从句 The fact is that we have lost the game.同位语从句 The news that we won the game is e*citing.whether/if as if if/whether,as if 虽有词义，但在从句中不作句子成分。主语从句 Whether he will accept the invitation remains a secret.宾语从句 Attitude determines whether/if people are successful and able to enjoy life.Everything dep

32、 Thats just what I want.同位语从句 The question who should do the work requires consideration.表五：考点梳理 表五：考点梳理 【考点一】考 察 名 词性 从 句 的引导词 一分二划三看三步法 一分即分清从句类型：即分清从句是哪一种名词性从句主语从句、宾语从句、表语从句和同位语从句 二划即划分出从句 三看即看从句句意是否完整：1.句意不完整缺连接代词：指人时，用 who,whoever作主语；whom,whomever作宾语;指物时，用 what,whatever作主语、宾语；which,whichever作主语

33、、宾语。2.句意完整缺连接副词：指时间时，用 when；指地点时，用 where,wherever；指原因时，用 why；指方式时，用 how。3.句意完整缺不作成分的连词:有含义的用 if,whether是否；无含义的用 that。【考点二】考 察 名 词性 从 句 的语序问题 在名词性从句中，除了关联词在从句句首外，其他局部应用述语序。而考生们往往使用疑问语序，特别是在以 wh引导的名词性从句中。克制这个问题的关键是要找准从句的主语。在试题的设置上会通过宾语从句、表语从句的语序来考察，尤其是一些与特殊疑问句有关的宾语从句或表语从句。These shoes look very good.I

34、wonder _.A.how much cost they are B.how much do they cost C.how much they cost D.how much are they cost 解析：选 C。根据题干中的及物动词 wonder 可知,how much 引导宾语从句，而名词性从句要用述语序，故排除疑问语序的 B、D 两项;A 项可以改为 how much they cost 或 how much they are worth。应选 C 项。【考点三】考 察 宾 语从 句 中 的否认转移 否认转移主要针对宾语从句。在宾语从句中，当谓语动词是 think/believe

35、/suppose/imagine/guess/e*pect/consider 等表示认为、相信、猜想意义的词，并且主语是第一人称，时态是一般现在时，形式上是否认主句谓语动词的否认词，实际上否认的是宾语从句。在反意疑问句中，其中的附加问句要与从句保持一致，而且要把否认词转移到从句中去。I dont believe he treated the child like that,did he Im sure youd rather she went to school by bus,_.表五：考点梳理 A.hadnt you B.wouldnt you C.arent I D.didnt she 解

36、析：选 B。题干中的 be sure 同 believe,而且句子的主语是第一人称，时态是一般现在时，所以附加问句反意疑问句与从句保持一致。【考点四】考 察 形 式主语、形式宾语 当主语从句较长，而谓语较短时，为了防止头重脚轻，常常将从句后置，而用 it 作形式主语，置于句首。动词后接复合宾语，也可用it 作形式宾语。不能用 this 或 that 来代替 it。It is a pity that he cant attend the party.We consider it necessary that he should improve his grammar.(that 不可以省略)_

37、is a fact that English is being accepted as an international language.A.There B.This C.That D.It 解析：选 D。分析题干可知，it 作形式主语，代替真正的主语 that 从句。【考点五】考 察 名 词性 从 句 中虚 拟 语 气的运用 (1)主语从句、宾语从句、同位语从句和表语从句都会涉及到虚拟语气，一些表示建议、要求、命令的动词，如 insist 坚持/suggest 建议/order命令/request要求、请求/require要求/remend(建议)/urge(催促,力劝)等后的宾语从句中的

38、谓语动词要用虚拟语气，即should+do动词原形，其中的 should 可以省略。对应的名词作主语跟表语从句，或对应的名词跟同位语从句，也要用虚拟语气。但是如果有其他意义则例外，如 suggest 表示暗示时,所跟的宾语从句就用述语气。The teacher suggested that we(should)have a rest.It is suggested that he should adapt himself to new conditions.My suggestion that he should adapt himself to new conditions hasnt be

39、en accepted.My suggestion is that we(should)read English newspapers to improve our English.(2)主语从句中的*些句型，如 Its necessary/essential/strange/apity/a shame/no wonder；Its(high)time that.等句型中也常用虚拟语气，构成形式也是should+动词原形。It is necessary that we should master a foreign language.It is high time that the childr

40、en should go to school.(should 不可以省略)表六：难点 用一个恰当的词完成以下句子，使之完整、正确 I believe _ you have done your best and _ things will get better 解析：that 在引导主语从句、表语从句和同位从句时，一般不省略。在引导宾语从句时,that 可以省略。当由两个 that 引导的从句作同一个动词的宾语时，第二个 that 不可省。故第一个空可填 that，也可不填;第二空填 that。以下情况 that 不可省略：.表六：难点 【难点一】that 的 省略问题 当 that 作介词宾语

41、时，that 不可省略。The reason lies in that she works harder than the others do.当宾语从句被 it 替代时，that 不可省略。She has made it clear that she will have nothing to do with the decision.当 that 引导的宾语从句中的状语紧靠 that 时，或 that 从句中含有主从复合句时，that 不可省略。Im sure that if youve lost it,you must pay for it.有插入语或其他成分把宾语从句和主句分开时，tha

42、t 不可省略。He thinks,Im afraid,that he is always right.当 that 引导的宾语从句的主语是非谓语动词或主语从句时，that 不可省略。They said that rubbing the girls leg might help.从句的主语是 that 时，that 不可省略。She says that that is a real gold ring.【难点二】whether 与if 用一个恰当的词完成以下句子，使之完整、正确 The question _ he will go or not has not been decided.Pleas

43、e let me know _ you want to go.解析：whether 可以引导主语从句、表语从句、同位语从句，而 if 不可以。在引导宾语从句时 whether 可以与 or not 直接连用，或是作介词宾语，但是 if 不可以。所以第题填 whether;第题填 whether 或 if 皆可。只能使用 whether 的情形如下：主语从句、同位语从句、表语从句中只能用 whether。1.Whether he will succeed is still unknown 2.The question is whether it will rain.介词后的宾语从句中只用 whe

44、ther。That depends on whether they will e by bus.后面直接跟动词不定式时只用 whether。He doesnt know whether to stay or not.宾语从句中既可用 whether 也可用 if 引导，但是假设后面紧接 or not 时，只能用 whether。We didnt know whether or not she was ready.【即学即练】Elephants have their own way to tell the shape of an object and _ it is rough or smoot

45、h.A./B.whether C.how D.what 解析：选 B。根据前面的动词 tell 可知,and 连接两个并列宾语，所以后面是宾语从句，由从句中 or 可知答案。用一个恰当的词完成以下句子，使之完整、正确 My opinion is _ everyone of us takes out$5 for Janes birthday present._ she said puzzled him.解析：that 与 what 引导名词性从句的根本区别在于 that 在所引导的名词性从句中不作任何成分，只起连接作用;what 在所引导的从句中可以作主语、宾语、表语、定语等成分。所以第题填 t

46、hat;第题填 What。.表六：难点 表【难点三】that与what 单项填空 One advantage of playing the guitar is _ it can give you a great deal of pleasure.A.how B.why C.that D.when 解析：选 C。从句表达的就是 one advantage 的具体容，is 后是表语从句，从句中的成分完整，所以所填引导词不作任何成分，应选 C。_ matters most in learning English is enough practice.A.What B.Why C.Where D.Wh

47、ich 解析：选 A。从题干的 is 看出前面是主语从句，从句中没有主语，所以用连接代词 what。B、C 两项是连接副词，在从句中作状语,故排除。【难点四】wh-ever 与 no matter wh-用一个恰当的词完成以下句子，使之完整、正确 _ wants to see this film can go with us tonight._ cold it is,I will go to school.解析：疑问词+ever 与 no matter+疑问词的区别是：前者既可以引导名词性从句，也可引导让步状语从句，而后者只能引导让步状语从句。第题空白处引导主语从句，须填 whoever;第题

48、空白处引导让步状语从句，填 however 或 how 皆可。【即学即练】单项填空 Could I speak to _ is in charge of International Sales,please A.anyone B.someone C.whoever D.no matter who 解析：选 C。根据后面是句子可以确定用连词，故排除 A、B 两项。介词 to 后面跟宾语从句，而 no matter who 仅能引导状语从句，应选 C。The poor young man is ready to accept _ help he can get.A.whichever B.howe

49、ver C.whatever D.whenever 解析：选 C。根据及物动词 accept 和后面的动词 help 可知,考察宾语从句，而从句中 help 是名词，所以引导词应该作定语。应选 C。【难点五】引 导 同 位语 从 句 与 用一个恰当的词完成以下句子，使之完整、正确 The news _ he told me yesterday is not true.The news _ he will go to Beijing is not true.六：难点 定 语 从 句的 that 的区别 解析：同位语从句中的连词 that 只起连接作用，不充当任何句子成分且不能省略，同位语从句一般

50、放在有抽象含义的名词后，用以解释名词的含义或容；定语从句中的关系代词 that 在从句中充当主语或宾语，在充当宾语时常可省略，定语从句是对先行词的限定和修饰。分析上述两题可知，第题是定语从句，故填 which 或 that;第题是同位语从句，故填 that。【难点六】it 作形式主 语 的 主语 从 句 与强 调 句 和定语从句 用一个恰当的词完成以下句子，使之完整、正确 It was in the hotel _ he stayed that we discussed the serious problem.It is only lately _ he had a family himsel
