# Think L0–L5 · 本地文件 → 腾讯云 COS 对照

上传前先看这一页。线上 Cursor 之后只认这些 COS 路径，不再读你电脑上的原目录。

## 桶信息（所有文件都进这里）

| 项 | 值 |
|---|---|
| 桶 | `s-class-1403296481` |
| 地域 | `ap-chengdu` |
| 对象键前缀 | `s-class/Think/source/` |
| 公网根 | `https://s-class-1403296481.cos.ap-chengdu.myqcloud.com/s-class/Think/source/` |

**不要**把中文文件夹名、空格文件夹名原样传上 COS。按下面的 ASCII 目录传；**文件名保持原样**。

推荐用 CosBrowser 或下面的脚本整夹上传。完整 2622 条对照在：

- `Think/data/folder-to-cos.tsv`（按文件夹）
- `Think/data/local-to-cos.tsv`（按文件）
- `Think/data/local-to-cos.json`（机器可读）

本地脚本（在仓库根、已配置 `.cos-config.json`）：

```bash
node Think/scripts/upload-source-to-cos.js --root "D:/第二版" --dry
node Think/scripts/upload-source-to-cos.js --root "D:/第二版"
node Think/scripts/upload-source-to-cos.js --root "D:/第二版" --kind tb-pdf
```

`--root` 指向本地 `第二版` 文件夹本身。

## 建议上传顺序

1. **教师用书 PDF**（课件截页主源，优先）
2. **学生用书 PDF**（扫描版，备查）
3. **学生用书音频 + 视频**（点读 / 跟读）
4. **练习册 PDF + 音频**
5. **教师资源包**（练习、测验、语法 PPT，可后传）

---

## 1. 三本核心 PDF（每个 Level 各 3 个）

学生用书是扫描版，线上做课件时优先切教师用书里的学生页。

完整 COS 路径：

`s-class/Think/source/{L0-L5}/teacher-pack/{短名}/{原文件名}`

例：

`第二版/教师资源/L0/教师资源包/Communication_Worksheets/Thk2e_BrE_L0_Communication_Unit_1.pdf`

→ `s-class/Think/source/L0/teacher-pack/communication/Thk2e_BrE_L0_Communication_Unit_1.pdf`

L5 教师资源包目前只有致谢文件（教师用书在 `tb/`）。缺的练习/测验以后补传到同一短名目录即可。

逐夹对照见 `Think/data/folder-to-cos.tsv`。

课件 HTML 仍在 Git 的 `Think/` 下；音视频 / PDF / 切页图只走 COS。

各级页「本级 COS 目录」里，学生用书、练习册、教师用书直接打开对应 PDF。音频、视频、教师资源包进入 `Think/files.html`，按文件播放或下载。COS 不提供目录网页，按钮不能指到文件夹地址。
