一、教学定位与目标
建议课时： 3 课时。
主题： 寻找丢失文件、事件顺序、过去的状态与正在发生的动作。
- 掌握 file, folder, screen, phone, video 等数码和校园词汇。
- 理解
was/were表示过去状态，初步感知was/were + -ing。 - 用
First—Then—After that—Finally有序复述。 - 区分事实、猜测与证据，找到音乐文件的去向。
二、重点与难点
- 重点：
is/am → was，are → were；顺序词；地点介词。 - 难点： 不要求学生全面掌握过去进行时，仅理解
Beep was dancing...的语义并会套用。
三、核心词汇与短语
| 词汇/短语 | 中文 | 例句 |
|---|---|---|
| missing / gone / safe | 丢失的/不见的/安全的 | The file is gone. |
| file / folder / screen | 文件/文件夹/屏幕 | Check the folder. |
| hide behind | 藏在……后面 | The mouse hides behind things. |
| hear / follow the sound | 听见/循声寻找 | They follow the sound. |
| toilet / stairs / playground / lake | 厕所/楼梯/操场/湖 | It is beside the lake. |
| toy boat / long stick | 玩具船/长棍 | Kevin gets the boat with a stick. |
| at night / on Friday evening | 夜里/周五晚上 | Beep danced at night. |
四、语法知识点
1. 过去状态 was/were
It was here on Friday. Now it is gone.I/he/she/it 配 was，you/we/they 配 were。
2. 顺序词
First 第一步，Then 接着，After that 之后，Finally 最后。用它们将零散情节连成完整叙述。
3. 过去进行时初步
Beep was holding the phone and dancing beside the lake.
小学阶段重点理解“当时正在……”，不延伸复杂时态对比。
4. 时间与地点介词
on Friday, at three o'clock, at night, in the garden, beside the lake。
五、阅读策略与三课时建议
- 用“听到音乐的地点”画路线图，再根据手机和照片找到证据。
- 笑点引导：Beep 为什么把手机放在船里？Mr Brown 为什么不希望那段视频入选？
| 课时 | 主要任务 | 产出 |
|---|---|---|
| 1 | 读任务卡，扫读找人物、地点和线索 | 线索表 |
| 2 | was/were与顺序词，路线复述 | 四步复述 |
| 3 | 角色采访、视频新闻播报、检测 | Missing Music Report |
六、课堂互动
- File Search： 学生按
Check the...指令找线索卡。 - Sound Trail： 听声音并用
near/beside/behind描述位置。 - Four-Step Story： 小组抽取图卡，必须用四个顺序词复述。
- Then and Now： 对比
It was... / Now it is... - News Interview： 采访 Beep：
Where were you? What were you doing?
