## 🧪 **實際測試數據**
|
||
|
||
### **T1. 測試句子**
|
||
|
||
#### **T1.1 語法錯誤測試**
|
||
**輸入**: "She just join the team, so let's cut her some slack until she get used to the workflow."
|
||
|
||
**語法錯誤**:
|
||
- `join` → `joined` (時態錯誤)

|
||
|
||
#### **T1.2 詞彙分類測試**（用戶A2等級）
|
||
**預期統計結果**:
|
||
- **太簡單啦**: 8個 (she, the, so, let's, her, some, to等)
|
||
- **重點學習**: 4個 (just, team, until, used等)
|
||
- **有點挑戰**: 3個 (join, slack, workflow等)
|
||
- **慣用語**: 1個 (cut someone some slack)
