教科版（五四学制）英语六下Unit4语法讲解及习题 一般过去时的疑问句 一、语法核心讲解 本单元核心语法为一般过去时的疑问句，分为一般疑问句（Yes/No问句）和特殊疑问句（Wh-问句）两类。 （一）一般过去时的一般疑问句 1. 结构公式 Did + 主语 + 动词原形 + 其他？ 肯定回答：Yes, 主语 + did. 否定回答：No, 主语 + didn't. 2. 核心规则 助动词统一用did，与主语单复数无关。 行为动词必须还原为原形。 简略回答仅用did/didn't，不重复行为动词。 3. 例句 Did you lose your schoolbag at the museum yesterday?（你昨天在博物馆丢了书包吗？） Yes, I did.（是的，我丢了。）/ No, I didn't.（不，我没丢。） Did the guide tell you the story of Pompeii?（导游给你讲了庞贝古城的故事吗？） Yes, she did.（是的，她讲了。）/ No, she didn't.（不，她没讲。） （二）一般过去时的特殊疑问句 1. 结构公式 疑问词 + did + 主语 + 动词原形 + 其他？ 2. 核心疑问词及例句 疑问词 提问内容 例句 When 时间 When did Andrew find the treasure?（安德鲁什么时候找到宝藏的？） Where 地点 Where did Li Mei visit the ancient city?（李梅在哪里参观的古城？） What 事物/动作 What did the special machine do?（这台特殊的机器做了什么？） Who 人物 Who did you go to the lost and found office with?（你和谁去的失物招领处？） How 方式/感受 How did the host feel when he saw the discovery?（主持人看到这个发现时感觉如何？） How much 价格 How much did the lost watch cost?（那块丢失的手表花了多少钱？） 3. 核心规则 疑问词置句首，后接“did + 主语 + 动词原形”。 行为动词用原形，不可用过去式。 用具体信息作答，无需yes/no。 （三）易错点警示 ❌ Did he found his keys? / ✅ Did he find his keys?（动词未还原） ❌ Where he did go last weekend? / ✅ Where did he go last weekend?（did位置错误） ❌ Yes, I lost. / ✅ Yes, I did.（简略回答错误） 二、习题 题型一：基础补全题 （A）一般疑问句补全 用括号内动词的适当形式补全，并完成简略回答。 1. ______ you __________ (see) my notebook in the classroom? — Yes, I __________. 2. ______ Li Mei __________ (have) a tour guide for her trip to Pompeii? — No, she __________. 3. ______ the volcano near Pompeii __________ (blow) up in 79 CE? — Yes, it __________. 4. ______ the farmers __________ (find) any ancient things in the field? — No, they __________. 5. ______ your dad __________ (lose) his passport at the airport? — Yes, he __________. （B）特殊疑问句补全 从when/where/what/who/how中选疑问词，结合括号内动词补全。 6. ______ __________ you __________ (do) at the lost and found office yesterday? 7. ______ __________ Andrew __________ (find) the hidden treasure? 8. ______ __________ the host __________ (feel) about the surprising discovery? 9. ______ __________ you __________ (go) with to the Sanxingdui Museum? 10. ______ __________ the accident __________ (happen) last night? 题型二：连词成句题 按正确顺序排列单词，注意大小写和标点。 11. did / you / lose / your / wallet / where /? _____________________________________________________________________ 12. when / did / the / city / Pompeii / disappear /? _____________________________________________________________________ 13. did / the / tour guide / help / you / learn / history /? _____________________________________________________________________ 14. how / did / people / find / the / ancient / site /? _____________________________________________________________________ 15. who / did / Andrew / speak / to /? _____________________________________________________________________ 16. did / the / ash / keep / everything / in / Pompeii /? _____________________________________________________________________ 17. how much / did / the / trainers / cost /? _____________________________________________________________________ 18. did / your / family / watch / TV / last / night /? _____________________________________________________________________ 题型三：动词形式填空题 用括号内动词的适当形式填空。 对话1 A: 19. __________ you __________ (look) for your lost key?
