2026-2027学年九年级英语上册语法精讲精练（人教版新教材） Unit4 Our Memory 核心语法：wh-特殊疑问词引导宾语从句（Unit3拓展延伸） 语法精讲 一、核心总结构 主句 + wh - 引导词 + 陈述句语序（主语 + 谓语） 二、wh 引导词三大特点： 1.有实际含义 2.在从句中充当句子成分（主语 / 宾语 / 表语 / 状语） 3.绝对不能省略 对比记忆： that：无词义、不充当成分、常可省略 if/whether：词义 “是否”，不充当主干成分，不可省略 wh - 疑问词：有词义、充当成分、绝不省略 三、分类讲解 + 例句 1. what 什么（作主 / 宾） 原特殊问句：What do you want? → I don’t know what you want.（what 作 want 宾语） 原句：What happened? → Nobody knows what happened.（what 作从句主语） 2. who 谁（主格，从句作主语） Who will come? → I wonder who will come. 3. whom 谁（宾格，从句作宾语，口语常用 who 代替） Whom are you waiting for? → I don’t know whom you are waiting for. 4. whose 谁的（定语，修饰名词） Whose book is this? → Can you tell me whose book this is? 5. which 哪一个（可做主、宾、定语） Which one do you like? → She asks which one you like. 6. when 何时（时间状语） When will he leave? → I want to know when he will leave. 7. where 在哪里（地点状语） Where does he live? → I don’t know where he lives. 8. why 为什么（原因状语） Why is he late? → Do you know why he is late? 9. how 怎样；如何（方式状语） How can I get to the park? → Could you tell me how I can get to the park? 拓展搭配：how old/how many/how much/how long/how often 全部适用相同规则 四、最高频考点：语序！（重中之重） 规则： 原来的特殊疑问句是疑问语序（助动词提前） 变成宾语从句，必须改成陈述句语序：主语在前，谓语在后 结构：引导词 + 主语 + 谓语 + 其他 ❌ Do you know where does he live? ✅ Do you know where he lives. ❌ I don’t know what are you doing. ✅ I don’t know what you are doing. 【特殊不用调整语序的特例】 三个固定句型本身就是 “疑问词 + 主语 + 谓语”，无需变化： What’s wrong (with sb)? What’s the matter (with sb)? What’s happening? ✅ Do you know what’s wrong with him?（正确，不用改成 what wrong is…） 五、时态规则（和所有宾语从句通用） 口诀：主现从任意，主过从倒退，真理永一现 主句一般现在时 → 从句时态根据事实自由选择 I know where he lives /lived/will live. 主句一般过去时 → 从句时态向后倒退一档 He asked where I lived. She wondered how she could solve the problem. 描述客观真理、自然现象，从句始终一般现在时 The teacher told us why the sun rises in the east. 六、必考同义转换：wh - 从句 ⇨ wh - 词 + to do 当主句主语 和 从句主语为同一个人时，可以简化！ 公式： 主句 + wh - 引导的宾语从句 = 主句 + wh - 词 + to do sth I don’t know how I should do it. = I don’t know how to do it. She doesn’t know where she will meet us. = She doesn’t know where to meet us. Could you tell me which one I can choose? = Could you tell me which one to choose? ⚠ 注意：if/whether 引导从句可以转换成 whether to do，不能写成 if to do I don’t know whether I should go. = I don’t know whether to go. 七、三大类宾语从句引导词完整汇总表 句型类别 引导词 词义 是否充当成分 可否省略 陈述句 that 无 不充当 通常可以省略 一般疑问句 if / whether 是否 不充当 不可省略 特殊疑问句 what/who/where/when/why/how… 有具体含义 充当主 / 宾 / 定 / 状 绝对不可省略 语法精练 一、单项选择 1. Could you tell me ____ I can improve my memory?
