高考总复习 英语 第二部分 语法突破 专题六 复合句 第1讲 名词性从句 一 名词性从句的基本概念及分类 名词性从句包括四种从句，即主语从句、宾语从句、表语从句、同位语从句。从句在主句中充当什么成分就叫什么从句。因为主语、宾语、表语、同位语这四种成分均可以由名词构成，故将这四种从句统称为名词性从句。 语法重点勤回顾 语法专题解读 语法重点勤回顾 语法专题解读 语法重点勤回顾 语法专题解读 写出黑体部分的从句类型 1．That she will help me made us happy.________ 2．I can understand what he said.________ 3．This is where I was born.________ 4．The fact that a heavy earthquake happened made me crazy.__________ 主语从句 宾语从句 表语从句 同位语从句 语法重点勤回顾 语法专题解读 Step 1：分析句子结构，理清题目考查的是哪一种从句。从句在主句中作主语就叫主语从句；作宾语就叫宾语从句；作表语就叫表语从句；作同位语就叫同位语从句。 Step 2：知道是什么从句后，再确定相应的连接词。使用哪个连接词取决于从句中缺什么成分，是否有实际意义，是指人还是指物，有没有介词或特殊结构等。 [解题步骤] 语法重点勤回顾 语法专题解读 如果从句中缺少主语、宾语或者表语，则考虑用连接代词；如果从句中既不缺少主语、宾语，也不缺少表语，但是缺少状语，则考虑用连接副词；如果既不缺少主语、宾语、表语，也不缺少状语，则考虑用从属连词。 1．____will win the match is still unknown. 2．I want to know ____ he has told you. 3．The fact is ____ we have lost the game. 4．The news ____ we won the game is exciting. [温馨提示] Who what that that 语法重点勤回顾 语法专题解读 二 主语从句 1.主语从句的构成：引导词＋简单句 2．引导词 连词：that，whether 连接代词：who(ever)，what(ever)，which(ever)，whom(ever) 连接副词：when，where，how，why，whenever，wherever，however 语法重点勤回顾 语法专题解读 3．4个注意点 ①陈述句语序； ②主语从句作主语，谓语动词用单数； ③that在主语从句中不能省略； ④句首只能用whether，不用if。 语法重点勤回顾 语法专题解读 what与that引导主语从句的区别 what引导主语从句时，表示“所……的(东西)”，并且在从句中充当句子成分；而that作为连词，引导主语从句时，其本身没有实际意义，不充当句子成分，通常不可省略。 What she was afraid of was their taking her daughter abroad. 她害怕的是他们带她女儿出国。 That he will refuse the offer is unlikely. 他不可能拒绝这个报价。 [温馨提示] 语法重点勤回顾 语法专题解读 三 宾语从句 1.宾语从句的构成：引导词＋简单句(宾语从句主要跟在动词、介词和某些形容词之后) 2．引导词 连词：that，whether，if 连接代词：what，whatever，who，whoever，whom，whomever，whose，which，whichever(在从句中作主语、宾语、表语或定语) 连接副词：when，whenever，where，wherever，how，however，why(在从句中作状语) 语法重点勤回顾 语法专题解读 3．4个注意点 ①陈述句语序； ②动词find，feel，think，consider，make，believe，guess，suppose，assume等后有宾语补足语时，需要用it作形式宾语，而将that宾语从句后置； ③hate，dislike，like，appreciate等动词以及动词短语see to，depend/rely on，take ...for granted；owe it to sb.that等，需要用it作形式宾语而将宾语从句后置； 语法重点勤回顾 语法专题解读 ④宾语从句的否定转移，将think，believe，suppose，expect，fancy，imagine等动词后面宾语从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。 I don't think I know you. 我想我并不认识你。 I don't believe he will come. 我相信他不会来。 语法重点勤回顾 语法专题解读 宾语从句中四种不能省略引导词that的情况 ①that从句作介词的宾语时； ②动词后跟有多个that引导的宾语从句时，只有第一个that可以省略，从第二个从句开始that不可省略； ③宾语从句前有插入语时； ④that引导的从句位于句首时。 [名师点津] 语法重点勤回顾 语法专题解读 四 表语从句 1.表语从句的构成：引导词＋简单句(表语从句主要跟在系动词之后) 2．引导词 连词：that，whether，as if，as though 连接代词：who，whom，whose，which，what，whoever，whomever，whichever，whatever(在从句中作主语、宾语、表语或定语) 连接副词：when，where，how，why，because(在从句中作状语) 语法重点勤回顾 语法专题解读 3．4个注意点 ①陈述句语序； ②if不引导表语从句； ③as if/though引导的表语从句常跟在特定动词后面，如seem，appear，look，taste，sound，feel等。 It sounds as if someone is knocking at the door. 听上去好像有人在敲门。 ④当主句的主语是reason时，表语从句一般由that引导，这种用法常见于句型“The reason why ...is/was that ...”。 The reason why he came late was that he got up late. 他来得晚是因为起晚了。 语法重点勤回顾 语法专题解读 [温馨提示] 句式 用法 例句 This/That is why＋结果 意为“这/那就是……的原因”，why 引导表语从句 That's why I want you to work there. 那就是我想要你在那儿工作的原因。 This/That/It is because ＋原因 意为“这/那是因为……”，because引导表语从句 It's just because he doesn't know her. 这仅仅是因为他不认识她。 表语从句的三个易混句式 语法重点勤回顾 语法专题解读 句式 用法 例句 The reason why ...is/was that ...   意为“……的原因是……”，why引导定语从句，that引导表语从句 The reason why he didn't come was that it was raining heavily. 他没有来的原因是(当时)雨下得很大。 语法重点勤回顾 语法专题解读 五 同位语从句 同位语从句在句子中作某一名词的同位语，一般位于该名词之后，进一步解释、说明该名词的具体内容。这些名词常见的有belief(信任)，possibility(可能性)，fact(事实)，idea(想法)，hope(希望)，doubt(怀疑)，news(新闻)，conclusion(总结)，suggestion(建议)，problem(问题)，order(命令)，answer(回答)，decision(决定)，discovery(发现)，explanation(解释)，information(信息)，knowledge(知识)，opinion(观点)，truth(事实)，promise(诺言)，report(报道)，thought(想法)等。 语法重点勤回顾 语法专题解读 1．同位语从句的构成：引导词＋简单句(同位语从句主要跟在抽象名词之后) 2．引导词 连词：that，whether 连接代词：who，whom，which，what，whose(在从句中作主语、宾语、表语或定语) 连接副词：where，when，why，how(在从句中作状语) 语法重点勤回顾 语法专题解读 3．3个注意点 ①陈述句语序； ②that只起连接作用，在从句中不作句子成分，无实际意义，不可省略； ③if不引导同位语从句。 语法重点勤回顾 语法专题解读 [温馨提示] 同位语从句与定语从句的区别 定语从句是形容词性从句，其作用相当于一个形容词，是用来修饰、限定前面的名词或代词的；同位语从句是名词性从句，其作用相当于一个名词，是对前面的名词作进一步解释的。 The news that he told me yesterday was true.(定语从句) The news that he won the game was true.(同位语从句) 语法重点勤回顾 语法专题解读 “三招定向”解决语法填空中的 名词性从句连接词问题 1．根据两句之间的意义和逻辑关系，或者根据句式结构判断句子是否是名词性从句。 2．一旦确定句子是名词性从句，就根据名词性从句中缺少什么句子成分来确定选用什么连接词。若从句中缺少主语、宾语、定语或表语，用连接代词；若缺少状语就用连接副词。 3．如果从句不缺少成分则要考虑意思是否完整，是否需要用whether/if；如果从句不缺少成分且意思完整，则用that。 解题方略理思路 技巧点拨 对点训练 ①_____ the student was late for school again made the teacher very angry. ②_____ surprised me most was that such a little girl could play the violin so well. ③_______ the hero went is not mentioned at the end of the story. ④The question is _________ we should accept their invitation. ⑤This is ______ they overcame the difficulties. ⑥China is no longer _____ it used to be. ⑦The reason why he was absent was _____ he was ill.
