每個單字都沒拼錯，段落還是可能不通。
Exercise is important. However, it is good for our health. Therefore, many people do not exercise.
問題不是 however 或 therefore 本身，而是句與句的關係沒有先想清楚。連接詞只能標示邏輯，不能替你製造邏輯。
先判斷關係，再選字。
| 句子關係 | 常用 LINK | 你在回答什麼？ |
|---|---|---|
| 原因 | because, since | 為什麼？ |
| 結果 | therefore, as a result | 所以發生什麼？ |
| 轉折 | however, yet | 和預期哪裡不同？ |
| 補充 | moreover, in addition | 還有什麼？ |
| 舉例 | for example, such as | 具體例子是什麼？ |
| 條件 | if, unless | 什麼條件下成立？ |
Teenagers often stay up late. However, they feel tired the next day.
Teenagers often stay up late. As a result, they feel tired the next day.
熬夜 → 隔天疲倦，是原因到結果，不是轉折。
段落 cohesion 的核心
不是每一句都加一個連接詞，而是讓讀者知道：這一句為什麼接在上一句後面。
把四句排成一條合理的因果鏈。
Students stay up late.
They feel tired in class.
Their concentration becomes worse.
They should reduce phone use at night.
請排成：原因 → 直接結果 → 學習影響 → 解決方法，再補上最適合的 LINK。
NEXT STEP
不要再背一長串連接詞，卻不知道它們為什麼出現。
