環境（Environment）幾乎每場 IELTS Task 2 都會出現一題，但初級詞彙早已被批改老師看膩——pollution, global warming, plants and animals, save the environment 這組字最多撐到 Band 6。

進階版環境詞彙的關鍵是抽象化與制度化：carbon footprint, mitigation strategies, ecosystem services, circular economy, biodiversity loss——一段 essay 嵌入 5-6 個，整體氣質立刻提升。

先複習 主題詞彙 · 環境（基礎），再對照 Task 2 主題 · 環境。

為什麼進階詞彙特別吃香

環境議題的考官多半受過環境政策訓練。看到 circular economy、just transition、ecosystem services 這些術語精準使用——直接判 Lexical Resource 7-8 分。看到 pollution is bad——再多論點都救不回來。

高頻搭配詞束

| 中文 | Collocation | 示範 | |------------------|-----------------------------------|----------------------------------------------------------------------------| | 緩解氣候變遷 | mitigate climate change | Mitigating climate change at scale requires coordinated international policy. | | 減少碳排 | cut carbon emissions | Cutting carbon emissions in heavy industry is the next decade's hardest task. | | 保育生物多樣性 | conserve biodiversity | Conserving biodiversity demands intact landscapes, not just protected pockets. | | 採取永續做法 | adopt sustainable practices | Mid-sized firms have adopted sustainable practices faster than expected. | | 過渡至再生能源 | transition to renewable energy | Transitioning to renewable energy underpins every credible net-zero plan. | | 推動環境保護 | promote environmental protection | Promoting environmental protection is now mainstream rather than fringe politics. |

避免這些被用到爛的字

| 過度使用 ❌ | Band 7+ 替換 ✓ | |------------------|-------------------------------------------------------------------------------| | pollution | air pollution / contamination / environmental degradation | | bad for nature | ecologically damaging / detrimental to ecosystems / environmentally harmful | | save the earth | protect the environment / preserve ecosystems / safeguard the planet | | cut down trees | deforestation / habitat clearance / forest loss |

提醒：在 Task 2 寫 save the earth 立刻顯得幼稚。換成 safeguard the planet 或 protect the environment——氣質差 1.5 個 Band。

題目脈絡：Some argue economic growth and environmental protection cannot coexist.

The supposed conflict between growth and the environment is increasingly a matter of timing rather than substance: a credible transition to renewable energy is now compatible with the same productivity gains that fossil-based expansion once delivered. Cutting carbon emissions at the speed required will not be painless, but a properly designed just transition retrains affected workers rather than abandoning them, while a carbon tax ensures that the cost of greenhouse gas emissions sits with those who generate them. The circular economy, by reusing materials that current systems treat as waste, simultaneously mitigates climate change and reduces import dependency. Critics warn of competitiveness losses, yet countries that adopt sustainable practices earliest tend to dominate the export markets that follow. Treating sustainability as a constraint on prosperity misreads the evidence; ignoring biodiversity and habitat loss entirely is the more reliable route to long-term economic damage.
