Where the English evening will be held has not yet been announced. Why he knew it was unknown. How it was done was a mystery. Who will win the match is still unknown. What we need is money. Whoever disobeys the rule will be punished. Whatever you can do helps. Whose face will flush is the liar. Which bus we should take is still a question. 5、由because引导的主语从句 Just because it’s red does not mean it’s cherry flavored. 牛刀小试： 单项选择 1.（24-25高一下·江苏扬州·期中） the ancient people built the pyramids in the past with primitive tools puzzled people for centuries.

(用适当的词填空) 答案 1．How 【详解】考查主语从句。句意：古代人是如何用原始的工具建造金字塔的，这个问题困扰了人们好几个世纪。空处引导主语从句，在句中作状语，表示“如何、怎样”，故应用连接副词how；句首字母大写。故填How。 2．What 【详解】考查主语从句。句意：我们昨天讨论的是目前非常热门的话题。分析句子可知，设空处引导主语从句，从句中缺少宾语成分，意为“……的事情”，所以为连接代词what引导；置于句首，首字母大写。故填What。 3．that 【详解】考查主语从句。句意：他突然意识到，自己在离开办公室之前忘记锁保险柜了。此处为固定句型“it occurred to sb. that...”，意为“某人突然想到……”，其中that引导主语从句，it是形式主语，真正的主语是后面的that从句。故填that。 4．Why 【详解】考查主语从句。句意：对于许多高中毕业生来说，为什么要上大学是一个很好的问题。分析句子可知，设空处引导主语从句，结合从句句意可知，从句需要意思“为什么”，所以为连接副词why引导该主语从句，作原因状语。故填why。 5．Why 【详解】考查主语从句。句意：玛雅文明为何会崩溃仍然是个谜。分析句子结构可知，“____ Maya civilization collapsed”是一个主语从句，由句意可知，这里需要一个表示原因的词来引导主语从句，所以用why，表示“为什么”，且句首时首字母应大写。故填Why。 考点（三）表语从句 1、定义 在句中作表语的从句叫表语从句。表语从句位于连系动词之后。 2、引导表语从句连词 从属连词that，whether，as if, because等 连接代词what，who，which，whose, whom 连接副词how，when，where，why等 1、that引导的表语从句 that引导的表语从句，从属连词只起连接作用，其中that无词义，一般不能省略。 这种从句往往对于主句主语内容进行进一步的解释说明。 例：The fact is that fish can’t go without water. 事实是鱼离开水不能存活。 2、Whether 引导的表语从句 whether引导的表语从句，whether 意为“是否”。if不能引导表语从句。 在从句中不作任何成分。 The question is whether the film is worth seeing.问题是这部电影是否值得看。 3、从属连词as if, because，as though等引导的表语从句 Because引导表语从句通常只用于“This/ That/ It is/ was because…”结构中。as if/though引导的表语从句常至于系动词look，seem，sound，be, become等后面，若表语从句所述的是非真实的情况，从句用虚拟语气；若所述的是事实或是极可能发生的情况，从句用陈述语气。It looks as if it is going to rain.好像快要下雨了。 It seems as if there will be a quarrel soon.好像要有一场争吵了。 4、连接代词和连接副词引导的表语从句 (1) 连接代词what, who, which, whom, whose除在句子中起连接作用外，还在从句中充当一定的成分，可作主语、宾语、表语、定语，且各有各的词义。 The problem is who should speak at the meeting. 问题是谁应该在会议上发言。 That is why they were late for the meeting. 这就是他们会议迟到的原因。 (2) 连接副词when, where, why, how除在句子中起连接作用外，在从句中还充当时间、地点、方式或原因状语，本身具有词义。 That’s why they were late for the meeting. 那就是他们迟到的原因。 Their difficulty is where they can raise enough money. 5、主语是表示建议、命令、要求。计划（suggestion, advice, order, request, proposal, plan）等名词，那么表语从句应用虚拟语气，即should + 动词原形，should常可以省略。 My suggestion is that we (should) leave the village right now. His plan is that we (should) persuade his mother to change her mind. 6、because/why引导的表语从句 (1)This/That/It is why＋表语从句 这/那就是……的原因 　 (2)This/That/It is because＋表语从句 这/那是因为…… ] (3)The reason why...is that＋表语从句 ……的原因是…… He didn’t work hard. That’s why he was fired.他没有努力工作。那就是他被解雇的原因。 The reason why the injection needs repeating every year is that the virus changes. 7、学习表语从句要注意的问题 (1) 当主语是the reason , the result 或 why引导的主语从句时，常用that 引导表语从句，不用because。 The reason why she keeps silent is that she doesn’t want to lose her job. 她保持沉默的原因是她不想丢掉工作。 (2) “That is why...”是常用句型，意为“那就是……的原因”；“That is because...” “这就是因为……” ；The reason why …is that …中的why引导的是定语从句，that 引导的是表语从句，表示“……的原因是……” He had seen the film before. That is why he did not see it last night. The reason why he was late was that he missed the train this morning. 牛刀小试： 1.（24-25高一下·天津·期中）The reason ______ I have to go is ______ my mother is ill in bed.

(2) 引导表语从句时 The question is whether she should have a low opinion of the test? (3) 引导从句作介词宾语时 Everything depends on whether we have enough money. (4) 从句后有“or not”时： (5) 后接动词不定式时。 Can you tell me whether to go or to stay? 4、连接代词和连接副词引导的宾语从句 连接代词what, who, which, whose, whoever, whatever, whichever； 连接副词how, when, where, why等，这些连接词都有词义，除引导从句外，还在从句中充当一定的成分，可作主语、宾语、表语、定语、状语等。这种宾语从句有疑问意义，但不是疑问句，不能用疑问语序，而用陈述语序。 例如：I don’t know what the little girl likes. Could you tell me which job I should take, please? 温馨提示 在demand, order, suggest, decide, insist, desire, request, command等表示要求、命令、 建议、决定等意义的动词后，宾语从句常用“(should) + 动词原形”。 I insist that she (should) do her work alone. 我坚持要她自己工作。 The commander ordered that troops (should) set off at once. 5、使用宾语从句应注意的问题 (1) 宾语从句的语序要用陈述语序 用who, whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。 I want to know what he has told you. 我想知道他告诉你什么了。 (2) 宾语从句的时态 注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用不同时态。当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现 象，则从句仍用现在时态。 He asked me if I was a teacher. 他问我是不是老师。 I know (that) he will study English next year. 我知道他明年要学英语。 The teacher told us that Tom had left us for America. (3) think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。 We don’t think you are here. 温馨提示: 在发生否定转移的句子中 （1）若陈述部分的主语为第一人称时，反义疑问句的人称及时态应与从句的人称和时态相对应； （2）当陈述部分为第二第三人称时，反义疑问句的人称时态和人称与主句的保持一致。I don’t believe your brother will finish the work on time, will he? 牛刀小试 1．（24-25高二下·江苏苏州·阶段练习）The historian believed steam power was the key to industrial revolution and the period brought about the appearance of an urban working class.

Neither of her parents knew she was so sad. (用适当的词填空) 答案 1．that 【详解】考查宾语从句连接词。句意：历史学家认为蒸汽动力是工业革命的关键，且这一时期带来了城市工人阶级的出现。steam power was the key to industrial revolution和the period brought about the appearance of an urban working class是并列的宾语从句，作动词believe的宾语；第一个宾语从句前省略了引导词that，空处引导第二个宾语从句，从句不缺成分，语义完整，用that引导，但第二个宾语从句that不可省略。故填that。 2．where 【详解】考查宾语从句连接词。句意：在太平洋中央，一座桥状的纪念碑矗立在亚利桑那号沉没残骸所在的地方。该空需要一个连词引导宾语从句作介词in的宾语，宾语从句中缺少地点状语，应填where在从句中作地点状语，表示“……所在的地方”。故填where。 3．what 【详解】考查宾语从句。句意：他是个典型的说谎者，为了你自己，你不要把他的话当真。动词take后接宾语从句，从句缺少宾语，指物，所以用连接代词what引导。故填what。 4．what 【详解】考查宾语从句。句意：这只是在这个展览中为你准备的内容的一小部分。of是介词，后面接宾语从句，所以空处引导宾语从句，从句中缺少主语，且表示“……的东西，……的事情”，所以用what引导该从句。故填what。 5．why 【详解】考查宾语从句。句意：艾玛关上门，放声大哭。她的父母都不知道她为什么这么难过。空处引导宾语从句。根据knew和she was so sad可知，这里指父母不知道她为什么如此伤心，强调原因，因此用why引导。故填why。 考点（五）同位语从句 1、同位语从句定义： 同位语从句在句中作某一抽象名词(advice, demand, doubt, fact, hope, idea, information, message, news, order, problem, promise, question, request, suggestion thought, truth, wish, word等)的同位语，一般位于该名词之后，说明该抽象名词的具体内容。 同位语从句通常由that引导，可用于同位语从句的名词有等。 The news that we won the game is exciting. I have no idea when he will come back home. 2、同位语从句连接词： (1) 引导的连接词that, whether引导的同位语从句，在句中不充当任何成分只起连接作用。 We will discuss the problem whether the sports meeting will be held on time. (2) 连接代词what, who, which；连接副词how, when, where, why引导同位语从句，此时引导词在从句中作相应的成分。 We haven’t yet settled the question where we are going to spend our holiday. 3、同位语从句的重难点： (1) 表达“是否”时，要用whether而不用if引导同位语从句。 I have no idea whether she likes the film. (2) 当主句的谓语较短，而同位语从句较长时，同位语从句常后置，构成隔式同位语从句。 Word came that the famous scientist would come to see us. (3) 在某些名词后的同位语从句中，其谓语动词要用虚拟语气：(should)+动词原形，常见的这类名词有：advice, demand, doubt, idea, order, problem, promise, request, suggestion, decision, recommendation等。 I made a suggestion that all the children (should) leave the building. 考点指导 名词doubt（怀疑）肯定形式后的同位语从句用whether引导； no doubt(不怀疑) 即否定形式之后的同位语从句用that 引导。 There is no doubt that he will win the game. 毫无疑问他会赢得比赛。 4、同位语从句和定语从句的区别 (1) that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。 I had no idea that you were here. 我不知道你在这里（that引导同位语从句，不能省略） Have you got the idea (that) this book gives you of life in ancient Greece？ 你知道这本书告诉你的古代希腊的生活吗？（that引导定语从句，作宾语，可以省略） (2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，而同位语从句是名词性的，其功能是对名词进一步补充说明。如果把先行词去掉，剩下的句子不正确，而把同位语从句前的名词去掉后，句子往往是正确的。 The news that he told me is not true. (3) wh-引导同位语从句本身含有疑问的含义；引导定语从句则没有疑问的含义。 This is the place where our English evening is to be held. 牛刀小试 1.（22-23高一下·吉林长春·阶段练习）There is no evidence ________ the meeting actually took place.

A．What, that B．As, what C．As, whether D．What, whether 答案： 1．D 【详解】考查名词性从句。句意：没有证据表明会议确实召开过。分析可知，空后的从句中不缺成分，句意完整，且从句是对evidence的解释说明，所以是同位语从句，用that引导。故选D项。 2．A 【详解】考查动词短语和同位语从句。句意：历史轶事总是容易被夸大，但摄影师声称他想用一个犹太婴儿的照片来愚弄纳粹分子，这一说法似乎是真实的。“be prone to”是固定短语，意为“易于……；有……倾向”，后接名词或动名词，“be prone to exaggeration”表示“容易被夸大”；“tend to do sth. (倾向于做某事)”，所以第一空用“prone to”。“he wanted to allow himself the pleasure of fooling the Nazis with the picture of a Jewish baby”是对抽象名词claim的具体内容的解释说明，是同位语从句，从句中不缺少成分，用that引导，所以第二空填that。故选A项。 3．A 【详解】考查同位语从句。句意：当她开始写一部小说时，我认为她不知道自己最终会写到哪里。设空处连接同位语从句，对idea进行解释说明，从句中缺少地点状语，故选A。 4．C 【详解】考查同位语从句和主谓一致。句意：许多学生没有复习关键规则的事实导致老师决定推迟考试。第一空引导同位语从句，解释说明“fact”的具体内容，从句成份和意义都完整，用that引导；第二空为主句谓语动词，句子的主语是“The fact”，是单数第三人称，句子陈述客观事实，用一般现在时。故选C项。 5．C 【详解】考查连词和同位语从句。句意：随着我们对宇宙的了解越来越多，也许有一天我们会回答其他星球上是否有生命的问题。第一空用As引导时间状语从句，有“随着”之意。第二空用whether引导同位语从句，意为“是否”，解释说明名词question。故选C。 考点六、名词性从句精练（一） 基础闯关 引导词填空 1.

What impressed me 【详解】考查主语从句、时态和动词。分析句子可知，句子为主语从句，“_____ _____ _____ most”在句中作主语，“impress”意为“给……留下深刻印象”，动词词性，“impress sb.”意为“给某人留下深刻印象”，应用“what”引导从句，在从句中作主语，指事物，句首单词首字母大写，根据句意和句中“was”可知，句子陈述的是过去发生的事，从句应用一般过去时，“impress”的过去式为“impressed”，空格处应填“What impressed me”。故填What impressed me。 2．What upset me 【详解】考查时态、主语从句和动词。根据句意可知，句子为主语从句，应用“what”引导从句，在从句中作主语，指事物，没有选择范围，“upset”意为“使心烦意乱”，动词词性，根据句中“was”可知，句子陈述的是过去发生的事，应用一般过去时，“upset”的过去式为“upset”，作谓语，“me”为人称代词宾格，意为“我”，作宾语，句首单词首字母大写，“What upset me”表示“让我心烦的”。故填What upset me。 3.What you did was horrible 【详解】考查主语从句和时态。“你的所作所为”可用主语从句表示，译为What you did，what在从句中作宾语；“太可怕了”译为形容词horrible，在句中作表语。分析句子可知，本句应使用“主语从句+系动词+表语”结构，且时态为过去时。故译为What you did was horrible。 4．It is surprising/ It is amazing 【详解】考查固定句型。句意：令人惊讶的是，他放弃了大城市的工作，选择在乡村工作。根据汉语提示“让人惊讶”可知，使用固定句型“It is amazing that”或者“It is surprising that...”，其中it作形式主语，that引导真正的主语从句，故填It is surprising或者It is amazing。 5．Whoever is involved in the case 【详解】考查主语从句。句意：无论谁与此案有关，都将接受进一步调查。根据汉语提示可知，表示“案件”可用名词case；表示“参与”可用短语be involved in；表示“凡是……的人”可用whoever来引导从句，再分析句式结构，此处用whoever来引导主语从句，whoever是第三人称，所以从句中谓语动词用第三人称单数形式，且从句用陈述语序。故答案为Whoever is involved in the case。 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 19 / 21 学科网（北京）股份有限公司 $$ 2025年新高一英语暑假提升精品讲义（人教版2019） 专题03名词性从句逆袭手册(四大从句连接词决胜攻略) 内容导航 思维导图: 图文结合,知识整合 考点聚焦：核心考点，有的放矢 重点速记：知识点和重难点梳理，查漏补缺 牛刀小试：知识点和关键点训练，能力提升 高频考点：模拟新题+提升专练，全面突破 思维导图 考点聚焦 考点（一） 名词性从句概述 考点（二） 主语从句考点梳理 考点（三） 表语从句考点梳理 考点（四） 宾语从句考点梳理 考点（五） 同位语从句考点梳理 考点（六） 名词性从句模拟精练 重点速记 考点（一） 名词性从句概述 1、定义：在句子中起名词作用的句子叫名词性从句。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句 2、名词性从句连接词： 引导名词性从句的连接词可分为三类： 名词性从句 词义 在词中所充当的成分 是否可以省略 从属连词 that 无意义 不充当充分 第一个宾从可以省略 if / whether 是否 不充当充分 不可 连接代词 what (ever) (无论)什么 主、宾、表 不可 which (ever) （无论）哪个 主、宾、定 不可 who (ever) （无论）谁 主、宾、表 不可 whom (ever) （无论）谁 宾语 不可 whose 谁的 定语 不可 连接副词 when(ever) （无论）什么时候 状语 不可 where(ever) （无论）在哪里 why 为什么 how(ever) （无论）怎样 考点（二）主语从句考点梳理 主语从句 在句子中起主语作用的从句叫主语从句。主语从句通常由从属连词that, whether, if引导，在从句中不充当任何成分。连接代词what, who, which, whom等，在从句中起名词的作用，作主语、宾语、表语、定语等。连接副词how, when, where, why在从句中作状语。 1、that引导的主语从句 that引导的主语从句可用形式主语it替代，而把that从句置于句子后部。从句放于句首时that不可省略，从句放于句子后部时that一般不能省略，口语中偶尔可以省略。that在主语从句中不作任何成分，只起连接从句的作用。 It is certain that they will agree. 温馨提示： what 与that 在引导主语从句时的区别 （1）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； （2）that在句中无词义，只起连接作用，在从句中不充当任何成分。引导主语从句、表语从句、宾语从句 同位语从句时，在口语或非正式文体中，引导宾语从句的 that 常可省略，但引导其他从句时一般不可省略。 如：That he is still alive is a wonder.（主语从句） My idea is that we can get more comrades to help in the work.（表语从句） I know (that) he is a good student.（宾语从句） The news that our team had won made us excited.（同位语从句） 2、主语从句能用it作形式上的主语 有时为避免句子头重脚轻，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。主语从句后的谓语动词一般用单数形式。常用句型如下： (1) It + be + 名词 + that从句 常用于这种句型的名词有：a pity, a shame, a fact, an honor, a wonder等。 It’s no wonder that she speaks English so well. 难怪她说英语那么好。 (2) It + be + 形容词 + that从句 常用于这种句型的形容词有：necessary, likely, right, wrong, important, certain, clear等。 It’s likely that he is the winner of this game.很有可能他是这场游戏的胜利者。 温馨提示：It + be + 形容词 (necessary, important, strange) + that从句常用should + do，其中should可省略。 It is necessary that we (should) live a low-carbon life. 我们过低碳生活是很必要的。 (3) It + be + 动词的过去分词 + that从句 常用于这种结构的过去分词有：known, believed, expected, said等。 It is said that that is where the famous singer was born. 温馨提示: It + be + suggested/ advised/ ordered/ insisted/ required + that从句应用should + do，其中should可省略。 It is suggested that the old man (should) go to the countryside to have a rest. 建议这位老人到乡村去休息下。 (4) It + 及物动词 + 宾语+ that 从句 It worried the woman that her son was always playing computer games. 儿子一直在玩电脑游戏，这让这个女人很担心。 (5) It＋不及物动词＋that从句 常用于这种结构的动词有：(seems, appears, happens, matters, turns out, occurs to sb, strikes sb hits sb等 It occurred to him he had an important conference to attend the next morning. 他突然想到，第二天上午他有重要的会议要参加。 It seems to me that you object to the plan. 在我看来你好像反对这个计划。 温馨提示： 当表语或宾语也为从句时不能用it做形式主语。 What moved us was that he lost his life in order to save others.使我们感动的是他为了挽救别人而献出了自己的生命。 3、由whether / if 引导的主语从句 （1）whether 引导既可位于句首，也可位于句尾; if 引导只能位于句尾。 （2） whether与or / or not 连用，可紧接其后，也可分开; if若要与or not 连用只能分开。 Whether he has signed the contract or not doesn’t matter. 他是否签了合同是无关紧要的。 Whether or not he has signed the contract doesn’t matter. 4、由连接代词或连接副词引导的主语从句 When we arrive doesn’t matter. Where the English evening will be held has not yet been announced. Why he knew it was unknown. How it was done was a mystery. Who will win the match is still unknown. What we need is money. Whoever disobeys the rule will be punished. Whatever you can do helps. Whose face will flush is the liar. Which bus we should take is still a question. 5、由because引导的主语从句 Just because it’s red does not mean it’s cherry flavored. 牛刀小试： 单项选择 1.（24-25高一下·江苏扬州·期中） the ancient people built the pyramids in the past with primitive tools puzzled people for centuries.

That’s why he was fired.他没有努力工作。那就是他被解雇的原因。 The reason why the injection needs repeating every year is that the virus changes. 7、学习表语从句要注意的问题 (1) 当主语是the reason , the result 或 why引导的主语从句时，常用that 引导表语从句，不用because。The reason why she keeps silent is that she doesn’t want to lose her job. 她保持沉默的原因是她不想丢掉工作。 (2) “That is why...”是常用句型，意为“那就是……的原因”；“That is because...” “这就是因为……” ；The reason why …is that …中的why引导的是定语从句，that 引导的是表语从句，表示“……的原因是……” He had seen the film before.

(2) 引导表语从句时 The question is whether she should have a low opinion of the test? (3) 引导从句作介词宾语时 Everything depends on whether we have enough money. (4) 从句后有“or not”时： (5) 后接动词不定式时。 Can you tell me whether to go or to stay? 4、连接代词和连接副词引导的宾语从句 连接代词what, who, which, whose, whoever, whatever, whichever； 连接副词how, when, where, why等，这些连接词都有词义，除引导从句外，还在从句中充当一定的成分，可作主语、宾语、表语、定语、状语等。这种宾语从句有疑问意义，但不是疑问句，不能用疑问语序，而用陈述语序。 例如：I don’t know what the little girl likes. Could you tell me which job I should take, please? 温馨提示 在demand, order, suggest, decide, insist, desire, request, command等表示要求、命令、 建议、决定等意义的动词后，宾语从句常用“(should) + 动词原形”。 I insist that she (should) do her work alone. 我坚持要她自己工作。 The commander ordered that troops (should) set off at once. 5、使用宾语从句应注意的问题 (1) 宾语从句的语序要用陈述语序 用who, whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。 I want to know what he has told you. 我想知道他告诉你什么了。 (2) 宾语从句的时态 注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用不同时态。当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现 象，则从句仍用现在时态。 He asked me if I was a teacher. 他问我是不是老师。 I know (that) he will study English next year. 我知道他明年要学英语。 The teacher told us that Tom had left us for America. (3) think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。 We don’t think you are here. 温馨提示: 在发生否定转移的句子中 （1）若陈述部分的主语为第一人称时，反义疑问句的人称及时态应与从句的人称和时态相对应； （2）当陈述部分为第二第三人称时，反义疑问句的人称时态和人称与主句的保持一致。I don’t believe your brother will finish the work on time, will he? 牛刀小试 1．（24-25高二下·江苏苏州·阶段练习）The historian believed steam power was the key to industrial revolution and the period brought about the appearance of an urban working class.

Neither of her parents knew she was so sad. (用适当的词填空) 考点（五）同位语从句 1、同位语从句定义： 同位语从句在句中作某一抽象名词(advice, demand, doubt, fact, hope, idea, information, message, news, order, problem, promise, question, request, suggestion thought, truth, wish, word等)的同位语，一般位于该名词之后，说明该抽象名词的具体内容。 同位语从句通常由that引导，可用于同位语从句的名词有等。 The news that we won the game is exciting. I have no idea when he will come back home. 2、同位语从句连接词： (1) 引导的连接词that, whether引导的同位语从句，在句中不充当任何成分只起连接作用。 We will discuss the problem whether the sports meeting will be held on time. (2) 连接代词what, who, which；连接副词how, when, where, why引导同位语从句，此时引导词在从句中作相应的成分。 We haven’t yet settled the question where we are going to spend our holiday. 3、同位语从句的重难点： (1) 表达“是否”时，要用whether而不用if引导同位语从句。 I have no idea whether she likes the film. (2) 当主句的谓语较短，而同位语从句较长时，同位语从句常后置，构成隔式同位语从句。 Word came that the famous scientist would come to see us. (3) 在某些名词后的同位语从句中，其谓语动词要用虚拟语气：(should)+动词原形，常见的这类名词有：advice, demand, doubt, idea, order, problem, promise, request, suggestion, decision, recommendation等。 I made a suggestion that all the children (should) leave the building. 考点指导 名词doubt（怀疑）肯定形式后的同位语从句用whether引导； no doubt(不怀疑) 即否定形式之后的同位语从句用that 引导。 There is no doubt that he will win the game. 毫无疑问他会赢得比赛。 4、同位语从句和定语从句的区别 (1) that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。 I had no idea that you were here. 我不知道你在这里（that引导同位语从句，不能省略） Have you got the idea (that) this book gives you of life in ancient Greece？ 你知道这本书告诉你的古代希腊的生活吗？（that引导定语从句，作宾语，可以省略） (2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，而同位语从句是名词性的，其功能是对名词进一步补充说明。如果把先行词去掉，剩下的句子不正确，而把同位语从句前的名词去掉后，句子往往是正确的。 The news that he told me is not true. (3) wh-引导同位语从句本身含有疑问的含义；引导定语从句则没有疑问的含义。 This is the place where our English evening is to be held. 牛刀小试 1.（22-23高一下·吉林长春·阶段练习）There is no evidence ________ the meeting actually took place.
