2026—2027 学年 · 沪教版（五四学制） 九年级英语上册核心语法精讲精练 Unit 3 Travellers' tales 核心语法：疑问词 + 不定式（核心语法精练） 班级：____________ 姓名：____________ 日期：____________ 学习目标 目标 完成标准 识别 能在语境中准确识别 question word + infinitive。 结构 能正确写出肯定、否定、疑问等核心结构。 辨析 能解释常见错误并完成句式转换。 运用 能围绕 Travellers' tales 主题完成阅读与表达任务。 课前发现：先观察，再归纳 阅读三组句子，写出中文意思，并圈出体现本课语法结构的部分。 1. We have not decided where to stay. ________________________________________________________________________________ 2. Could you show me how to use the map? ________________________________________________________________________________ 3. The problem is what to take for the trip. ________________________________________________________________________________ 发现提示 比较句中“主语、核心结构、后续成分”之间的关系，再尝试用一句话概括规律。 一、核心概念 “疑问词 + to do”可在句中作主语、宾语或表语，把“该做什么、怎样做、何时做、去哪里”等问题压缩成简洁结构。常见疑问词有 what, which, who, when, where, how。 二、结构与用法 功能/结构 形式或含义 例句 what to do 做什么 I know what to pack. how to do it 怎样做 She showed us how to book a ticket. where/when to do 在哪里/何时做 They discussed when to leave. which/who to choose 选哪个/选谁 I cannot decide which route to take. 三、易混点辨析 例句 辨析 I don’t know what to buy. what 作 buy 的宾语。 I don’t know how to buy it. how 表方式；buy 后仍需宾语 it。 Why to do... why 通常不直接用于“疑问词 + 不定式”。 四、常见错误：先判断，再改正 错误句 正确句 I don’t know how to do. I don’t know what to do. Can you tell me where to go there? Can you tell me how to go there? / where to go? She asked why to cancel the trip. She asked why they should cancel the trip. We decided what route to take it. We decided what route to take. Tell me when leave. Tell me when to leave. 五、解题四步法 步骤 自问清单 ① 看语境 句子要表达什么时间、对象和逻辑关系？ ② 找核心 主语、谓语、先行词或疑问词分别是什么？ ③ 套结构 结构中需要原形、过去分词、形容词还是不定式？ ④ 再检查 主谓一致、时态、语序、拼写是否正确？ 六、分层练习 A. 基础理解：选择最恰当的答案 1.
