专题十名词性从句 第一节基本知识与基本概念 【什么是名词性从句？】 顾名思义，主语从句在句子中作主语。有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。从句作主语时，谓语动词一般为单数形式。如: What I saw was beyond any verbal description. That his hair was turning grey worried him a bit. Why the company denied the contract is still unknown. When and where the government will build a city square is under discussion. It is pretty annoying that a small part of the machine is missing. It remains to be seen whether the new novel will be well received. 【宾语从句】 在句子中作宾语的从句就是宾语从句。由于这是同学们接触比较早的一种从句，应该问题不大。所以在近年的高考题中，以宾语从句的知识作为考点的题目较少。但是，宾语从句也有自己的特殊情况，如介词的宾语，形容词的宾语，宾语从句提前和并列的宾语从句等现象。如： We assumed that there would be more than 100 guests. He told the police in detail what he saw and heard. Nobody is sure what humans will look like in a million years. That will depend on whether they can get the chance. Whether I will have the time I am not sure at the moment. The conductor complained that we were not gifted in singing and that he would never come again. 【表语从句】 表语从句的最重要脸谱就是它们应该出现在系动词的后面。如： The only question left is how often the workers are paid. His idea for the coming weekend is that we go skating. 【同位语从句】 从脸谱上看，同位语从句最为麻烦。因为它们也是出现在一个名词的后面，起着解释说明的作用。
名词性从句在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。 主语从句(subject clauses)在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、、关系代词、连接副词等。引导主语从句的关联词有从属连词that、whether，关系代词：who, what, which, whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever等。 That you don’t like him is none of my business.你不喜欢她不管我的事。 What he said is true. 他说的是真的。 Do you remember how he arrived almost at the end of the party?你记得他几乎是在宴会快结束时才到的吗？ This party's really where it's at, man! 啊，这个晚会真棒！Tell us how you fulfilled the heavy task ahead of schedule.告诉我们,你们是怎样提前完成这一艰巨任务的。 We have reason to believe that the fighting on the border may develop into a full-blown war. (喻)我们有理由相信边境上的冲突可能发展成一场全面战争。 He said that he would come. 他说他要来。
名词性从句 名词性从句指在复合句中起名词作用的从句，它在句子中可作主语、宾语、表语或同位语。名词性从句既是中学英语教学的重点，也是高考考查的热点。 一、名词性从句的分类 名词性从句包括主语从句、宾语从句、表语从句和同位语从句。其连接词有that, if, whether；连接代词who, what, which；连接副词when, where, how, why等。 考查热点一：对主语从句的考查 主语从句在复合句中充当主语，它可以放在主句谓语动词之前。但为了保持句子平衡，多数情况下可用it作形式主语，而把主语从句置于句尾。 考查热点二：对宾语从句的考查 宾语从句在句子中作及物动词或介词的宾语。如果主句的谓语动词是及物动make, find, see, think等，则把宾语从句置于宾语补足语之后，用it作形式宾语。另外，某些作表语的形容词，如sure, happy, glad, certain 等之后也可以带宾语从句。 考查热点三：对表语从句的考查 表语从句在句子中作表语，位于主句中的系动词之后。 一、什么是表语（predicative） 在形式上，位于系动词后的就是表语。从含义上讲，表语是回答主语“是什么”或“怎么样”的语法成分。即是指“是”字句“是”字后面的成分。表语就是起表述作用的句子成分。它修饰的是主语。表语是用来说明主语的身份、性质、品性、特征和状态的。表语须和连系动词一起构成句子的复合谓语。表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、动词的-ed、从句来充当，它常位于连系动词（be, become, appear, seem等）之后。 Albert Einstein was a famous professor of physics.

A. Who B. It C. As D. What 【答案】 D 【解析】【分析】句意：委员会成员清楚的是，总统不会向他们的要求让步。that the President will not give in to their demands.这个句子作表语； is clear to the members of the committee这是主语从句，这里缺少主语从句的连接词，并且连接词在句中作主语，it是代词，不是了；连接词，故排除B；as作主语时，是在定语从句中，故排除C；who指人，根据表语指的事情，不是人，故排除A；what在主语从句中可以作主语或宾语，指事，符合句意，故选D。 【点评】考查名词性从句，本题涉及what引导的主语从句。 3．Has it been announced ______? A. when are the planes to take off B. that are the planes to take off C. where are the planes to take off D. when the planes are to take off 【答案】 D 【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。 【点评】考查名词性从句，it作形式主语，关系副词when引导的从句作真正的主语。 4．In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question. A. focused; whether B. focused; if C. has focused; whether D. has focused; if 【答案】 C 【解析】【分析】考查时态和主语从句。根据In the past decade,在最近的几十年里，可知句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。故选C。
高中英语定语从句讲解及练习 定语从句是高中重点知识，也是高考常考点，大家也不容易掌握，这篇文章主要教你关系代词引导的定语从句 关系副词引导的定语从句判断关系代词与关系副词限制性和非限制性定语从句等内容，有例题讲解定语从句在句中做定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。 关系代词有：who, whom, whose, that, which等。 关系副词有：when, where, why等。 18.1 关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如： Is he the man who/that wants to see you? 他就是你想见的人吗？（who/that在从句中作主语） He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语） 2）whose 用来指人或物，（只用作定语, 若指物，它还可以同of which互换）。例如： They rushed over to help the man whose car had broken down.那人车坏了，大家都跑过去帮忙。 Please pass me the book whose （of which）cover is green.请递给我那本绿皮的书。 3）which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。例如： A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语） The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。（which / that在句中作宾语） 18.2 关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 1）关系副词when, where, why的含义相当于\"介词+ which\"结构，因此常常和\"介词+ which\"结构交替使用。例如： There are occasions when （on which）one must yield.任何人都有不得不屈服的时候。 Beijing is the place where（in which）I was born.北京是我的出生地。 Is this the reason why （for which）he refused our offer?这就是他拒绝我们帮助他的理由吗？ 2）that代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代when, where, why和\"介+which\"引导的定语从句，在口语中that常被省略。例如： His father died the year （that / when / in which）he was born.他父亲在他出生那年逝世了。 He is unlikely to find the place （that / where / in which）he lived forty years ago. 他不大可能找到他四十年前居住过的地方。 18.3 判断关系代词与关系副词 方法一：用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如： This is the mountain village where I stayed last year. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。 判断改错： （错）This is the mountain village where I visited last year. （错）I will never forget the days when I spent in the countryside. （对）This is the mountain village （which）I visited last year. （对）I'll never forget the days （which）I spent in the countryside. 习惯上总把表地点或时间的名词与关系副词where, when联系在一起。此两题错在关系词的误用上。 方法二：准确判断先行词在定语从句中的成分（主、谓、宾、定、状），也能正确选择出关系代词/关
高二英语名词性从句 要点精讲 高考重点要求 1．掌握主语从句、宾语从句、同位语从句、表语从句的基本句型结构。 2．弄清名词性从句的连词意义，掌握其用法。 3．根据句子语义确定使用何种从属连词。 名词从句分为：主语从句、宾语从句、同位语从句、表语从句。我们看一下它们的属性。 如：that he failed the entrance examination 1)________made all of us surprised. 2)He told me ________. 3)The result is _______. 4)The news _____surprised me. 我们在四个句子中可以填入that he failed the entrance examination这个句子，发现都可成立。从上例不难看出，从本质上讲，这四类句子的属性是相同的，即：都起名词作用，只不过称谓不同,在整个句子中担当成分不同而已。 纵观几年高考，对复合句的考查重在连词，名词从句也不例外，基本上是针对引导词设题。 引导词的分类： 1．连接代词：what , who ,whom ,whose , which ，whatever,whoever,whichever,且这些词在从句中担当主、宾、表、定语作用。 2．连接副词：why, when , where, how 在从句中充当时间、地点、原因、方式、程度状语。 whether , if在从句中不充当成分，但整个句式中不可缺少，用以体现事件的不确定性。 3．that 是名词从句中一个很活跃的词，但它只起连接作用，陈述某一事实，引导宾语从句时某些情况可以省略。 针对如下情况，可进行对比： 1)______he will come to call on is uncertain . 2)_______he will come to call on us is uncertain. 3)_____ he will come to call on us makes us unhappy. 从第一句中我们可以看出主语从句本身并不完整，缺少call on 的宾语，应加who; 第二句中表语为uncertain ,可知主语部分为未知信息，可加入when, why ,how ,whether 等; 第三句表一种已知事实，故应加入that 。 二．that ,whether, if 在名词从句中的使用情况

名词性从句 在句子中起名词作用的句子叫名词性从句(Noun Clauses）。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。 第一节知识点讲解 顾名思义，主语从句在句子中作主语。有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。从句作主语时，谓语动词一般为单数形式。如: What I saw was beyond any verbal description. That his hair was turning grey worried him a bit. Why the company denied the contract is still unknown. When and where the government will build a city square is under discussion. It is pretty annoying that a small part of the machine is missing. It remains to be seen whether the new novel will be well received. Tips: 主语从句的that绝对不能省去。因为句子是不能做主语的，故用that引导。若去掉则没有了主语，而宾语从句的that可省。 主语从句：That he is right is known to all of us. 宾语从句：We all know (that) he is right. 1. It 作形式主语和it引导强调句的比较 It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 b) It doesn’t interest me whether you succeed or not. 我对你成功与否不感兴趣。 c) It is in the morning that the murder took place. 谋杀案是在早上发生的。（强调句型） d) It is John that broke the window. 是John打碎的窗户。（强调句型） 2. 用it 作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that … 事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识
名词性从句知识归纳 名词性从句是指在句子中相当于名词的从句，主要包括主语从句、宾语从句、表语从句和同位语从句。名词性从句不是修饰性从句，而是复合句中的主干。 e.g. That the boy failed again in the exam disappointed his mother. （主语从句） I know that he is writing his composition in his room. （宾语从句） The question is how we can finish it on time. （表语从句） The fact that some Chinese are still poor is really a great problem. （同位语从句） 一、宾语从句---及物动词、介词、部分形容词（certain, sure, glad, afraid, frightened, happy, pleased, sad, sorry, surprised, upset, satisfied等）后 e.g. I believe (that) he is honest. (that不充当从句内的任何成分，一般情况可省略) I’m glad that you are satisfied with your job. (that不充当从句内的任何成分) He doesn’t care if/whether it isn’t a fine day. (if/whether不充当从句内的任何成分) Please tell me what you want. (what充当从句内的宾语) She always thinks of how she can work well.(how充当从句内的状语) I don’t believe whatever he said. (whatever充当从句内的宾语，意为“任何事”) I’ll take whoever wants to go. (whoever从当从句内的主语，意为“任何人”) 【宾语从句要点拓展】1. that引导宾语从句时一般可以省略，若由and或or连接两个宾语从句时，第一个从句中的that可以省略，而第二个分句前的that不可省略。 e.g. He told me (that) they could not decide what to do and that they asked my advice. 2. whether和if引导宾语从句一般可以互换使用，但以下情况只能使用whether (1) whether可与or not连用e.g. I want to know whether he will see the film or not.
定语从句总结 一：定语后置的总结 （1）介词短语作定语：the landlady in the bad situation / the way in error / the thief with a gun / the communication in English / The student in sorrow didn’t pass the English exam. （2）表语形容词作定语：the presidents alive in the U.S.A are all male. （3）不定合成代词被修饰：Although I had dinner tonight, I still need something delicious to have. （4）副词作定语：the students here are all come from Shenyang. （5）不定式作后置定语：the destination to go / the cookbook to use / the movie to cast / the match to fire / the classical music to listen / the hammer to use / the task to finish （6）现在分词作定语：the man pronouncing the wrong pronunciation is a principal. （7）过去分词作后置定语：the service given in the hotel is 5-star. / the signal signed by the students are for cheating in the final exam. (P10-1) English is a language spoken all around the world. (P10) In only fifty years, English has developed into the language most widely spoken and used in the world. （8）定语从句：（P4）The lesson (that) we can learn from Chuck and all others who have unusual friends is that friends are teachers. 二：定语从句的概念和公式特点 (P3-1): 关系代词在从句中作主语 Chuck is a businessman who is always so busy that he has little time for his friends. 先行词（被修饰的名词或代词）+ 关系词（起连接作用的代词和副词）+（,）定语从句（在句中作成分）
英语名词性从句十大考点全攻略 Who/whoever，what/whatever等的用法区别 一般说来，what/who等含特指意义，而whatever/whoever等含泛指意义，意为“无论什么/无论谁”。 Itisgenerallyconsideredunwisetogiveachild____heorshewants. A.however B.whatever C.whichever D.whenever 解析：答案是B，whatever引导一个宾语从句，并且作wants 的宾语。这里的whatever不能改成what，因为题意想表达的显然是“无论孩子要什么就给他/她什么事不明智的”，具有泛指的概念。同时要注意，这里whatever也不能改用nomatterwhat，因为后者只能引导状语从句。比较下例： Ican’trememberatthemomentwhohassaidthewords.(这里的who表特定的某人) Where，when，why等连接副词引导的名词性从句 Where，when，why等连接副词也可以引导名词性从句，使用的关键是：这个词必须符合句子的逻辑要求。 —IdrovetoZhuhaifortheairshowlastweek. —Isthat____youhadafewdaysoff？ A.why B.when C.that D.where 解析：答案是A，why引导的从句作表语，同时why在从句中作原因状语。这里之所以选why，而不是when或where等，唯一的依据便是句子的逻辑含义，及语境。
“介词+who(m)引导的宾语从句”与“介词+whom”引导的定语从句的区别 介词后面的引导词用主格还是宾格，决定于它在宾语从句中作主语还是宾语。 Itwasamatterof____wouldtaketheposition. A.who B.whoever C.whom D.whomever 解析：答案是A。这是一个含宾语从句的复合句，作介词of宾语的，是后面的整个句子，而不是宾语从句的引导词，由于这里引导词在从句中作主语，所以要用主格who(作宾语时自然要用whom)。 名词性从句中有插入成分时 此时应注意两点：一是从句仍然不倒装，而在插入成分上倒装；二是要注意主语的主格和宾格的选择。 ____youhaveseenbothfighters，____willwin？ A.Since；doyouthinkwho B.As；whoyouthink C.When；whoever D.Since；whodoyouthink 解析：根据上面的讲解，不难知道答案是D。其中doyouthink 是插入成分，其余部分是宾语从句，作think的宾语；由于引导词在从句中作主语，所以要用主格who(不用whom)。 引导词that的省略 引导宾语从句时，that通常可以省略，但引导主语、表语和同位语从句时，that不能省。例如：
