當主動讀者 · 逐句拆反論結構
主動讀者邊讀邊想反論；作者成功駁倒，你才更該接受他的論點。
National Park City 例： Counter：Opponents maintain that most cities don't have enough green space. Ack：Although it's true that park space varies widely, Ref：even small steps will lead to improvements in human health.
範文 Oslo 段 5： Counter：Opponents objected that without cars, businesses would suffer. Ref：…yet this hasn't happened — the result of careful planning.
辨識題型 · T／F／NG
判定
條件
True
文章明說，或可合理推論
False
文章有相反資訊
Not Given
文章完全沒提。⚠️ NG ≠ False，沒提到不代表錯
例：「Urban indoor farms are more common in cold climates」「Vertical farms use apps to deliver food」文章未提 → NG（不是 False）。

「However, the cost of LED lights is rapidly falling.」這句是？
寫作 · 因果論文
因果論文 (cause-effect essay) 範文「How Restricting Cars Has Changed a City」（pp.126–127，挪威 Oslo）。可選四種焦點：
焦點
結構
例
focus on causes/reasons
Cause(s) → Event
三個理由採用垂直農場
focus on effects
Event → Effect(s)
城市被野生動物影響的方式
focus on causes and effects
Cause(s) → Event → Effect(s)
範文 Oslo 即此型
focus on a cause/effect chain
Cause → Effect/Cause → Effect
一環扣一環
Learning tip · cause vs reason：cause 多指自然／物理／歷史過程（火災、事故、疾病、戰爭）；reason 多指人為可控的決定或行為。非同義詞、不可亂代。
文法 · 因果連接詞 Cause and Effect Connectors
類型
後接什麼
成員
preposition + cause 介系詞引導原因
名詞片語
because of, due to, thanks to, as a result of, as a consequence of
transition + effect 轉折詞引導結果
獨立子句
as a result, consequently, therefore
例：Because of the tightly controlled growing conditions, vertical farmers don't use pesticides.（介系詞＋名詞片語） Birds with shorter wings survived. As a result, genes for short wings became more common.（轉折詞＋子句）
易錯：because of / due to / thanks to 不可接子句（✗ because of it is expensive）；as a result / consequently 不可接片語。最常見仍是 because（接子句）與 so（接結果）。

易錯點 · 錯 vs 對
① 行為 ≠ 演化：foxes 夜獵、crows 借車屬行為改變（自己學、不傳基因）；cliff swallow 翅膀大小屬演化（基因層次、跨世代）。
② vertical farms 用太陽能？→ False：靠 LED 電力、電多來自非再生能源，這正是 critics 攻擊點。
③ 介系詞 vs 轉折詞：because of／due to／thanks to 後接名詞片語；as a result／consequently 後接獨立子句。寫錯詞性高頻扣分。
④ NG ≠ False：文章沒提到 ≠ 錯誤。⑤ main idea 別選太細的支撐細節。⑥ 寫 refutation 務必用 however／yet 等對比連接詞。
