直通新高考英语 初升高衔接精讲精练 第九讲 名词性从句 学习目标 1. 理解名词性从句的概念，知道它在句中充当主语、宾语、表语和同位语。 2. 掌握名词性从句“三大变身”：that + 陈述句、whether/if + 陈述句、特殊疑问句陈述句语序。 3. 掌握引导名词性从句的特殊疑问词及表语、同位语从句的注意事项。 本讲导读 名词性从句之所以让很多同学头疼，是因为它“把一整句话塞进另一句话里当名词用”。诀窍只有一条：任何简单句想充当另一个句子的成分，都要先“变身”——借助引导词变成名词性结构。本讲用“三大变身”帮你化繁为简：① that + 陈述句；② whether/if + 陈述句；③ 特殊疑问句改成陈述句语序。学会这三招，主语、宾语、表语、同位语从句一网打尽。 一、名词性从句的概念 Concept 名词性从句在功能上相当于名词，在句中作主语、宾语、表语和同位语。一个句子不能直接作另一个句子的成分，需要借助引导词“变身”为名词性从句。 YaoMing is tall is a fact. ×（两个谓语，错误） That YaoMing is tall is a fact. √（that 引导的从句作主语） ★ 三大变身一览 变身 结构 含义 第一大变身 that + 陈述句 陈述事实，that 无实义（宾语从句中可省） 第二大变身 whether / if + 陈述句 表示“是否” 第三大变身 特殊疑问词 + 陈述句语序 what / who / when… 在从句中充当成分，语序不倒装 二、第一大变身：that + 陈述句 = 名词 用 that 引导一个陈述句，使其成为名词性成分。that 无实义，在宾语从句中可省略；主语从句中常用 it 作形式主语，将 that 从句后置。 That YaoMing is tall is a fact. = It is a fact that YaoMing is tall. 主语从句 I know (that) YaoMing is tall. 宾语从句 My opinion is that YaoMing is tall. 表语从句 The opinion that YaoMing is tall is true. 同位语从句 三、第二大变身：whether/if + 陈述句 = 名词 用 whether/if 引导陈述句，表示“是否”。注意：主语从句、表语从句、同位语从句一般只用 whether，不用 if。 Whether you will come tomorrow is important to me. 主语从句 I want to know whether/if you will come tomorrow. 宾语从句 My question is whether you will come tomorrow. 表语从句 The question whether you will come tomorrow bothers me. 同位语从句 💡 💡 易混点 whether 与 if 都表“是否”，但主语从句、表语从句、同位语从句中一般用 whether； 介词后、带 or not、带 to 不定式前也只用 whether（如 whether or not / whether to go）。 四、第三大变身：特殊疑问句的陈述句语序 = 名词 将特殊疑问句（Why are you so clever?）改为陈述句语序（why you are so clever），即在从句中作成分、语序不倒装。 Why you are so clever is a mystery. 主语从句 I don’t know why you are so clever. 宾语从句 My question is why you are so clever. 表语从句 The question why you are so clever interests me. 同位语从句 引导名词性从句的特殊疑问词分为疑问代词和疑问副词。 ① 疑问代词 what/who/which/whose 在从句中既起连接作用，又作成分（主语、宾语、表语、定语）； ② 疑问副词 when/where/why/how 起连接作用，并在从句中作状语，后跟完整句子。 类别 词 含义/例句 疑问代词 what(ever) 什么：What he does is very important. 疑问代词 who(ever) 谁：I wonder who will teach us. 疑问代词 which(ever) 哪一个：I don’t know which (book) I should choose. 疑问代词 whose 谁的：The question is whose book it is. 疑问副词 when 什么时候：When Tom will arrive is not known. 疑问副词 why 为什么：I don’t know why he is here. 疑问副词 how 如何：I don’t know how he came here. 五、表语从句及同位语从句的注意事项 Notes on Predicative & Appositive ① 表语从句中可用 because 引导，如 This/That is because...（强调原因）； ② 常后跟同位语从句的抽象名词：fact, belief, idea, problem, question, information, decision, news 等； ③ 同位语从句的分离：为使结构平衡，同位语从句与所解释的名词之间可能被其他成分分隔，如 An idea came to her that she might try another way. 六、小结 Summary 类型 引导方式 要点 主语从句 that+陈述句 / whether/if / 特殊疑问词 that 无实义，常用 it 作形式主语后置 宾语从句 that+陈述句 / whether/if / 特殊疑问词 that 可省略；注意语序 表语从句 that / whether / 特殊疑问词 / because This is because... 同位语从句 that / whether / 特殊疑问词 常跟抽象名词，可分离 课后练习 1. 汉译英 1. 众所周知，地球围绕太阳转。 2. 我建议你应该花更多时间学习英语。 3. 他今天晚上是否来还不确定。 4. 那时为什么我想让你在这工作。 5. 他赢得比赛的消息令人激动。 2. 语法填空 1.
