Task 2 寫負面影響時，bad 永遠是第一個跳出來的字——也永遠是最該換掉的字。它太口語、太籠統。學術替換：adverse。
字義
Adverse (adj.) — preventing success or development; harmful or unfavourable, especially in a formal, scientific, or policy context.
關鍵：***adverse* 幾乎只用在書面、報告、學術場合**。Speaking 用會略生硬，但 Task 2 是它的主場。
5 個 Band 7+ 例句
- Excessive screen time has well-documented adverse effects on adolescent sleep.
- The medication carries a small risk of adverse reactions in elderly patients.
- Farmers continued to harvest the crop despite adverse weather conditions.
- Rapid urbanisation has had an adverse impact on traditional community ties.
- Policymakers must weigh potential benefits against possible adverse consequences.
常見錯誤
搭配記住四組：adverse effects / adverse impact / adverse conditions / adverse reactions。其他名詞要小心——an adverse person 是錯的（人不會是 adverse）。
Register 提醒：別在 Speaking Part 1 講天氣時用 adverse weather — 太書面。日常聊天用 bad weather / awful weather；Task 1 描述圖表異常、Task 2 寫政策後果——adverse 才上場。
注意拼字：adverse ≠ averse — averse 是「厭惡」（risk-averse）。一個字母、完全不同意思。
同等級替換（Band 7+）
- Detrimental — Long working hours are detrimental to family life.（更強烈）
- Negative — The reform had a negative effect on small retailers.（中性、最安全）
