【英语】2019届二轮复习语法专题名词性从句（21页word版）

‎2019届二轮复习语法专题名词性从句 学习目标 名词性从句一直备受高考命题者的关注，近几年来的高考题主要考查在具体语境中连接词的选择，尤其是连接词what和that的辨析，以及whether 与if表示“是否”时的区别。因此，正确区分名词性从句的类型，根据在从句中的作用和所表达的意义，确定恰当的连接词是一轮复习的重点。此外，名词性从句和定语从句的辨析，也是高考考查的重点。 ‎ 一、认识各种名词性从句 ‎ 名词性从句相当于名词，可分别作句子的主语、表语、宾语和同位语。因此，名词性从句具体分为主语从句、表语从句、宾语从句和同位语从句。名词性从句中的连接词有连词that / whether / if，连接代词what / who(m)/ which / whose / whatever / whoever / whomever / whichever，连接副词where / when / why / how 。‎ 从名词性从句在句中所起的作用来说，名词性从句是句子不可缺少的一部分，和句子的其他成分之间也不会用逗号隔开。而定语从句和状语从句是句子中的修饰成分，去掉之后不会影响句子主体结构的完整性。这是判断是否是名词性从句最主要的特征。如：‎ ‎ I wonder how much these shoes cost. (宾语从句，不可省去)‎ ‎ He is the very man I look after. (定语从句，修饰the man)‎ ‎ You may borrow the book as long as you keep it clean. (状语从句)‎ ‎1． 主语从句 ‎ Who will go is not important. ‎ ‎ It doesn't matter so much whether you will come or not. (形式主语it代替后面的真正的主语从句)‎ ‎ 注意：that引导主语从句放于句首时，不能省略。‎ ‎ That he suddenly fell ill last week made us surprised. ‎ ‎2． 表语从句 ‎ The question was who could go there. ‎ ‎ My idea is that we can get more people to help in the work. ‎ ‎ That is why the brothers wanted to make a bet. ‎ ‎ It looked as if it was going to rain. ‎ ‎3 . 宾语从句 ‎ I hope (that) everything is all right. ‎ ‎ 注意：(1)that在引导宾语从句时，常可省略，但如果有两个以上的宾语从句时，最后一个从句的that不能省略。如：‎ ‎ I know (that) he has just graduated from college and that he is looking for a job. ‎ ‎(2) 如果动词宾语后又有补语，那么要使用it作形式宾语，然后把宾语从句放在补语之后。如：‎ ‎ I make it known that we'll be invited to the ball. ‎ ‎(3) 如果主句的谓语动词的时态是一般过去时，那么从句的时态要采用相应的与过去有关的时态，但如果从句描述的是客观事实，从句时态不可调整“呼应”。如：‎ ‎ She remembered that she had left her wallet at the school gate. ‎ ‎ Our teacher said that light travels faster than sound. ‎ ‎4． 同位语从句 ‎ 同位语从句在句中作某一名词的同位语，一般位于该名词(如：news, fact, idea, suggestion, promise等)之后，说明该名词的具体内容。如：‎ ‎ I have no idea when he will be back.‎ ‎ The fact that he had not said anything surprised everybody. ‎ 注意：‎ ‎ 在动词：一坚持(insist)、二命令(order，command)、三建议(suggest，advise，recommend)、四要求(demand，require，request，ask)后的宾语从句和这些动词的过去分词后的主语从句，以及这些动词的名词引出的表语从句和同位语从句中，谓语部分常用(should)do形式。如：‎ ‎ He insisted that he (should) try once again. ‎ ‎ His advice is that everyone (should) do his best to help the ‎ poor girl. ‎ ‎ It is required that students (should) attend at least 90% of the lectures. ‎ 二、名词性从句的连接词 ‎ 名词性从句的连接词是名词性从句中最核心的问题，也是高考的常考点。连接词的选择要考虑它在从句中的作用和所表达的意义。‎ ‎　‎ 连接词 词义 在句中所 例句 作成分 从 属 连 词 ‎　‎ that ‎/‎ ‎/‎ The problem is that we don't have enough money.‎ ‎　‎ ‎　‎ if/ whether 是否 ‎/ ‎ The question is whether they have so much money.‎ ‎　‎ 连接词 词义 在句中所 例句 作成分 连 接 代 词 ‎　‎ ‎　‎ who/‎ whom/‎ which/‎ whose/‎ what 原疑问代词的意义；what更常表示：the thing that / the …that 所……的东西/……‎ 主语、宾语、表语、定语 ‎①Pay attention to what the teacher said. ‎ ‎②Who kept the door open all night was unknown.‎ whoever/‎ whomever ‎/ which‎ ever/ ‎ whatever ‎ 无论谁/ 无论哪个(些)/无论什么 主语、宾语、表语、定语 ‎①Whoever breaks the law will be punished. ‎ ‎②You can take whichever book you like. ‎ ‎　‎ 连接词 词义 在句中所作成分 例句 连 接 副 词 when/ where/ why/ how ‎ 原疑问副词的意义或“……的时间(the time when)；……的地点(the place where)；……的原因(the reason why)”；……的方式(the way that)‎ 状语 ‎①When he will go is unknown. ②I wonder why he tried to avoid me. ‎ ‎③This room is where I was born. ‎ ‎④This is how we work. ‎ 错误罗列 ‎1． what与that ‎(1) 【误】 All what he did was for you. ‎ ‎ 【正】 What he did was for you. ‎ ‎ 【正】 All that he did was for you. ‎ ‎(2) 【误】 I was thinking that I could do for you. ‎ ‎ 【正】 I was thinking what I could do for you. ‎ ‎ 【解析】 what引导名词性从句，what相当于the thing that/ the …that/ all that等，具体的意义要根据上下文确定。在名词性从句中，what既有意义，又在从句中作一定的成分，而that无意义，且在从句中不作成分。‎ ‎2． who与 whoever ‎ 【误】 Who is the first to come will get a gift. ‎ ‎ 【正】 Whoever is the first to come will get a gift. ‎ ‎ 【正】 Anyone who is the first to come will get a gift. ‎ ‎ 【解析】 whoever引导名词性从句，意为“无论谁”，相当于anyone who；而who意为“谁”。‎ ‎3． whether与if ‎(1) 【误】 They don't know if to go there. ‎ ‎ 【正】 They don't know whether to go there. ‎ ‎(2) 【误】 It depends on if we have enough time. ‎ ‎ 【正】 It depends on whether we have enough time. ‎ ‎ 【解析】 在以下情况只能用whether不能用if：‎ ‎① 作介词宾语时，连接词一般用whether。‎ ‎ It all depends on whether they will come back. ‎ ‎② 后面直接跟or not 时，用whether。‎ ‎ I didn't know whether or not he had arrived in Wuhan. ‎ ‎③ 主语从句、表语从句和同位语从句中，只能用whether。‎ ‎ Whether the meeting will be put off has not been decided yet. ‎ ‎ The question is whether they have so much time. ‎ ‎④ whether可与动词不定式连用，但if不能。‎ ‎ I have not decided whether to go or not. ‎ ‎⑤ whether可引导一个让步状语从句，表示“不管，无论”，而if不能。‎ ‎ Whether he comes or not, we will begin our party on time. ‎ ‎4． whoever 与whomever ‎ 【误】 Please give the book to whomever needs it most. ‎ ‎ 【正】 Please give the book to whoever needs it most. ‎ ‎ 【解析】 此处，whoever在从句中作主语，因此不能用whomever。名词性从句引导词的选择要注意其意义及它在从句中所作的成分。‎ ‎5． 【误】 He will win the match is certain. ‎ ‎ 【正】 That he will win the match is certain. ‎ ‎ 【正】 It is certain that he will win the match. ‎ ‎ 【解析】 that位于句首引导主语从句时，不能省略。‎ ‎6． 【误】 What we bought was some bananas. ‎ ‎ 【正】 What we bought were some bananas. ‎ ‎ 【解析】 what 引导的从句作主语时，若表示复数概念，谓语动词则用复数。‎ ‎7． 名词性从句的语序 ‎ 【误】 So now you know what should you do.‎ ‎ 【正】 So now you know what you should do.‎ ‎ 【解析】 名词性从句应用陈述语序。‎ ‎8． 【误】 There's a fact that English is being accepted as an important language. ‎ ‎ 【正】 It's a fact that English is being accepted as an important language. ‎ ‎ 【解析】 It is a fact that…句型中，It为形式主语，真正的主语为后面的that…从句。it不能换成there。‎ ‎9． 【误】 He is late.
