2026-2027学年九年级英语上册语法精讲精练（人教版新教材） Unit3 Smart Learning 核心语法：宾语从句（that / if / whether引导） 语法精讲 一、总前提回顾 宾语从句结构：主句 + 引导词 + 陈述句语序（主语 + 谓语…） 三类引导词分工： 三类引导词分工： that：承接陈述句 if / whether：承接一般疑问句，含义：是否 ⚠所有宾语从句必须使用陈述语序！ 第一部分：that 引导的宾语从句 1. 来源 直接把陈述句转变为宾语从句，用 that 引导。 原陈述句：He likes drawing. 放入宾语从句：I know (that) he likes drawing. 2. that 的特点 ① 无汉语意思，不在从句充当任何成分； ② 多数情况可以省略； ③ 常用主句动词：think, know, believe, hope, say, find, feel, agree, remember 等。 例句： She says (that) she misses her family. 她说她想念家人。 I believe (that) we can win the game. 我相信我们能赢得比赛。 3. 必考难点：that 不能省略的两种情况 （1）两个并列的宾语从句，第二个从句前的 that不可省 ✅ He thinks (that) English is important and that we should learn it well. ❌ He thinks (that) English is important and we should learn it well. （2）主句与从句之间有插入语隔开时，that 不省略 I found, to my surprise, that he failed the exam. 4. 拓展：否定转移（that 从句高频考点） 主语为 I / We，谓语动词：think, believe, suppose, expect 语义否定放在主句，从句不否定 中文：我认为他不会来 ❌ I think that he won’t come. ✅ I don’t think (that) he will come. 第二部分：if 和 whether 引导宾语从句 1. 来源 由一般疑问句转化而来，翻译为：是否 原疑问句：Does he live here? → I wonder if/whether he lives here. 2. 相同点 在大多数场景下，if = whether，可以互换 ✅ I don’t know if he will come. = I don’t know whether he will come. 3. 核心考点：只能用 whether，不能用 if 的 5 种场景（必背） （1）后面紧跟 or not ✅ I don’t know whether he will come or not. ❌ I don’t know if he will come or not. （2）放在介词之后作介词宾语 ✅ It depends on whether you work hard. ❌ It depends on if you work hard. （3） 后面接动词不定式 to do ✅ She hasn’t decided whether to travel. ❌ She hasn’t decided if to travel. （4）与 or 连接两个并列选择 ✅ I don’t know whether he will stay or leave. （5）置于句首引导宾语从句时 ✅ Whether he can pass the exam, no one knows. 4. 易混区分：if 的两个身份（超级易错题） （1）宾语从句中 if = 是否，时态遵守宾从时态规则 I don’t know if he will come. 我不知道他是否会来。 （2）条件状语从句中 if = 如果，遵守【主将从现】 If he comes, I will tell you. 如果他来，我会告诉你。 翻译区分最简单：翻译成 “是否”→宾从；翻译成 “如果”→状语从句。 三大引导词对比表格 引导词 来源 词义 能否省略 关键要点 that 陈述句 无含义 通常可省；并列从句第二个 that 不可省 不作句子成分 whether 一般疑问句 是否 不可省略 适用范围更广，很多场景不能换成 if if 一般疑问句 是否 不可省略 不能和 or not 连用、不能放介词后、不能接 to do 二、时态规则（适用于 that /if/whether 所有宾语从句） （1）主句现在时，从句时态根据句意自由选择 I know that he lives / lived / will live here. I don’t know if he has finished homework. （2）主句过去时，从句时态通常倒退一档（主过从必过） He said (that) he liked music. He asked whether I would join them. （3）客观真理、自然常识，永远用一般现在时 The teacher told us that the earth goes around the sun. 三、典型正误对比（避坑） ❌ I wonder if will he come. ✅ I wonder if he will come.（陈述语序！主语在前） ❌ I think he isn’t right. ✅ I don’t think that he is right.（否定转移） ❌ I’m interested in if he wins. ✅ I’m interested in whether he wins.（介词后只用 whether） 语法精练 一、单项选择题 1. I think ____ reading improves our memory.
