雙圓餅題寫成「2000 年 X%、2024 年 Y%」的逐項對照 = Band 6 天花板。本篇用全球能源生產結構 2000 vs 2024 示範怎麼用「結構性轉型」overview，並處理 negligible / cede ground / dominate while losing share 三組能源題招牌詞。
題目與數據
The two pie charts below show the proportion of world energy production by source in 2000 and 2024. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
資料（單位：% of total world energy production）：
| 能源來源 | 2000 年 | 2024 年 | |---------------------|---------|---------| | 石油 Oil | 38 | 30 | | 煤 Coal | 25 | 22 | | 天然氣 Natural gas | 22 | 24 | | 核能 Nuclear | 7 | 5 | | 水力 Hydro | 6 | 7 | | 風能太陽能 Wind/solar | 1 | 11 | | 其他 Other renewables | 1 | 1 |

¹ The two pie charts compare the share of world energy production attributable to seven different sources in 2000 and 2024.
² Overall, although fossil fuels continued to dominate the global energy mix in both years, their combined share contracted noticeably, with the most striking shift being the surge in wind and solar power from a negligible fraction to over a tenth of total output.
³ In 2000, oil was easily the largest single source at 38%, followed by coal at a quarter and natural gas at 22%, meaning these three carbon-intensive fuels together accounted for 85% of world production. ⁴ By 2024, oil had ceded ground to 30% and coal had slipped to 22%, although gas edged up marginally to 24%.
⁵ Renewables and low-carbon sources, meanwhile, gained collective momentum. ⁶ Wind and solar's share rose elevenfold from just 1% to 11%, while hydro inched up to 7%; nuclear was the only category to lose ground further, dropping from 7% to 5%.
句句 Band Descriptor 解析
- 句 1 — Task Achievement: attributable to seven different sources — 學術改寫。
- 句 2 — Task Achievement (Overview): Band 7+ overview 黃金結構——although fossil fuels continued to dominate, their combined share contracted, with the most striking shift being... 同時點出「不變」「微變」「最大變化」三層。
- 句 3 — Grammar Range: meaning these three carbon-intensive fuels together accounted for 85% — 分詞片語把三類加總，避免逐項列舉。
- 句 4 — Lexical: had ceded ground / had slipped / edged up marginally — 三個動詞分別描述「明顯減少／稍減／略增」。
- 句 5 — Coherence: meanwhile + 段落 topic sentence。
- 句 6 — Lexical + Grammar: rose elevenfold from just 1% to 11% + the only category to lose ground further — 倍數 + 排他性描述。

本篇避開的常見錯誤
錯誤：6+1 個類別全描述。 雙圓餅題 7 大類 × 2 個年份 = 14 個數字，逐一寫完字數爆量、focus 消失。
本範文的解法——分組三層：
- 化石燃料三大類（oil / coal / gas）合併成「碳排能源整體萎縮但仍主導」一段
- 再生 + 低碳（wind/solar / hydro / nuclear）合併成另一段，挑出 wind/solar 為主角
- other renewables (1% 不變) 直接捨去——不是 main feature
這就是 select main features 的真意：不是「都寫」而是「挑代表」。
