Join the information naturally; do not copy the question-and-answer format. ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 六 离堂前检验 3分钟 10. Write about one thing you really did yesterday and one thing you did not do. Then ask a classmate one question about yesterday. I __________________________________________________________________. I did not ___________________________________________________________. My question: ________________________________________________________ 我的检查顺序 先看时间 → 分清 be 和行为动词 → 检查主语 → 看 did 后是否还重复用了过去式。 我最需要再练的是：□ 不规则变化 □ was / were □ did 后的原形 □ 问句语序 参考答案与教学提示 开放题所列答案仅作示例。表达不同但符合文本、理由成立，应予认可；先肯定思考依据，再帮助学生修正语言。 一至二 从例子归纳规律 1. a：Last month，went；b：Last Saturday，came；c：performed。c 的时间承接 b，为 last Saturday。规则填 in the past；选择 need not。过去语境可以由前文建立，不必每句都出现 yesterday。 2. looked：多数动词直接加 -ed；moved：以不发音的 e 结尾加 -d；tried：辅音字母＋y 结尾，变 y 为 i 加 -ed；dropped：符合条件时双写词尾辅音再加 -ed；took：不规则变化，需整体记忆。 双写规则应说完整：重读闭音节中，词尾为一个元音字母加一个辅音字母，通常双写词尾辅音再加 -ed，w、x、y 一般不双写。stop、plan、drop 可作本课典型例子，不宜概括为“所有辅音结尾都双写”。 3. played。play 的 y 前是元音字母 a，直接加 -ed；carry 的 y 前是辅音字母 r，才变 y 为 i。 三 两种句式分别处理 4. a：was，were；b：did not / didn’t；c：Did。be 动词的否定在 was / were 后加 not，疑问句将 was / were 移到主语前，不加 did。 5. 示例：Did 已经表达过去，后面的行为动词用原形，所以应为 “Did you visit the museum?”。这是帮助学生理解变化的说法，不将 did 当成可以替代所有过去式的万能词。 6. a：Were，was；b：Did，didn’t；c：Were，were；d：did，brought。a 的问句主语是 you，用 were；答句主语变成 I，用 was。 四 纠错不仅要改词 Wrong form Correction Reason hold held Yesterday 建立过去语境；hold 的过去式是不规则形式 held。 brought bring did not 后用动词原形。 was were there be 结构中，many visitors 是复数，过去式用 were。 教学提示：先由学生独立圈出错误，再说出依据。不要把纠错做成教师一次性公布整段答案。 参考答案与迁移评价 五 问句和报道 8. 可接受问句： a. Where did you meet? b. What did you make? c. Did you buy ready-made birds? d. Who did you give the birds to? / Where did you send the birds? e. How did you feel? d 的问题要能引出学校图书馆这一接收方；只问 “What did you do?” 虽然语法正确，但信息目标不够明确。 9. 示例，四句话： Last Thursday, our Craft Club met in the art room and made paper birds. We did not buy ready-made birds. We gave our birds to the school library. We felt proud of our work. 可把 felt proud 与前句合并，同时另写一句有依据的活动信息。不得把记录里的 did not buy 写成 bought；不必为了凑句数虚构时间、数量。 六 个人经历 10. 示例：I played table tennis after school yesterday. / I did not watch TV yesterday. / Did you visit the library yesterday? 以学生真实经历为准。 检查位置 观察学生是否做到 肯定句 过去事件中的主要动词有恰当过去式。 否定与疑问 行为动词句用了 did not 或 did；其后的动词回到原形。 be 动词 根据主语选择 was 或 were，未误加 did。 交际意义 问题能询问缺失信息，短文能清楚还原记录。 根据错误安排下一步 若错在 held、brought 等形式，可让学生把本课出现的不规则动词按“原形—过去式—一个活动短句”整理四组。若错在 did visited，重做最小对比：I visited … / I didn’t visit … / Did you visit …? 每组只换一个活动，避免一次加入过多新词。 第 页 共 页 学科网（北京）股份有限公司 $
