百分比資料的魔咒——寫成「從 X% 漲到 Y%」流水帳。本篇示範三個百分比題招牌詞：converge, narrow the gap, reach parity，並用 2005–2025 英國分齡網路使用率示範怎麼寫「差距縮小」這個主要特徵。

¹ The line graph compares the proportion of UK residents using the internet daily, broken down into four age groups, over the twenty-year period from 2005 to 2025.
² Overall, daily internet use climbed significantly across every age bracket, with the gap between younger and older users narrowing sharply — though adults aged 75 and above remained some way behind the rest throughout the period.
³ In 2005, use was already widespread among 16-to-34-year-olds at 72%, and this group was the first to reach near-saturation, effectively levelling off at 99% from 2020 onwards. ⁴ The 35-to-54 bracket followed a similar trajectory, climbing from 48% to 97% and essentially reaching parity with the youngest group by the end of the period.
⁵ Older users showed the steepest relative growth. ⁶ The 55-to-74 group more than quintupled, from 18% to 92%, while adults over 75, despite starting from a mere 4%, rose to 68% — a seventeenfold expansion, though they remained the only group yet to approach universal use.
句句 Band Descriptor 解析
- 句 1 — Task Achievement: 改寫題目。broken down into four age groups 是題目原文 breakdown 的進階寫法。
- 句 2 — Task Achievement (Overview): 同時寫趨勢（都漲）+ 差距變化（縮小）+ 例外（75+ 仍落後）。三個主要特徵一句內——Band 7+ overview 的黃金結構。
- 句 3 — Lexical: near-saturation / effectively levelling off 描述「接近飽和然後持平」。
- 句 4 — Lexical: reaching parity with — 百分比題招牌，表示「追平」。
- 句 5 — Coherence: showed the steepest relative growth 開段 topic sentence，直接點出該段主角。
- 句 6 — Grammar Range: despite starting from a mere 4%... 讓步結構 + yet to approach 否定式未來。

本篇避開的常見錯誤
**錯誤：用 percent 而不用 percentage point。 從 48% 到 97% 的「差距」是 49 percentage points（不是 49%）。但描述使用率本身**就用 percent / %。這兩個詞 mix 起來 = Grammar Range 扣分。
本範文迴避這個地雷的方式——全部描述使用率本身（X%），避免談「差距幾個百分點」；談差距時用 narrowing sharply / reaching parity 這類質性描述。
