手機使用年齡是 2024 年起爆紅的 Task 2 考題——法國、英國、荷蘭都已立法，考題跟著出現。本篇示範 Band 7+ 立場明確又不偏激的寫法。

題目

Some people think that children should not be allowed to use smartphones before the age of 14. Others believe this restriction is impractical and unnecessary.

To what extent do you agree or disagree with the proposed age limit?

Give reasons for your answer and include any relevant examples from your own knowledge or experience. Write at least 250 words.

題型：Opinion (Agree/Disagree)——雖然提到兩方，但最後一句只問 To what extent do you agree，所以是 opinion 題，不是 discussion。我的立場：agree, with one qualification。

完整範文（293 字）

¹ Whether children should have access to smartphones before reaching their mid-teens has become one of the most contentious parenting debates of the current decade. ² I broadly support the proposed age limit of 14, although I would argue that how the restriction is enforced matters as much as the ban itself.

³ The primary reason I agree relates to adolescent brain development. ⁴ The regions that govern impulse control and emotional regulation continue to mature well into the late teens, which leaves younger children unusually vulnerable to the dopamine-driven design of social applications. ⁵ A 2023 Stanford study of over 4,000 pre-teens found that those who received a personal smartphone before the age of 12 reported significantly higher rates of anxiety and sleep disturbance four years later. ⁶ Such evidence suggests that delaying full device ownership is not an arbitrary precaution but a measurable protective measure.

⁷ A further consideration is the erosion of unstructured social time. ⁸ Childhood friendships have historically been built through face-to-face play, conflict and repair — processes that smartphones compress into shallow, screen-mediated exchanges. ⁹ Admittedly, a blanket ban risks isolating children whose peer groups communicate primarily through messaging apps, which is why I favour a calibrated policy rather than outright prohibition. ¹⁰ Restricting smartphones while allowing basic phones for safety would preserve parental peace of mind without sacrificing the developmental benefits of a phone-free childhood.

¹¹ In conclusion, I agree with the age limit of 14, though I regard the design of the policy as equally important. ¹² Given what recent research reveals about adolescent vulnerability, the default setting for childhood should be less, not more, exposure to technologies engineered to capture attention.

句句解析

§1 — Intro

  • 句 1 (Hook): "Whether children should have access... mid-teens has become one of the most contentious parenting debates..." — paraphrase（before 14 → mid-teens），contentious debates 是 Band 7 搭配。
  • 句 2 (Thesis): "I broadly support the proposed age limit of 14, although..." — 明確立場 + 預告 qualification。

§2 — 第一個理由

  • 句 3 (Topic sentence): "The primary reason... relates to adolescent brain development." — 一句話切入科學理由。
  • 句 4 (Explanation): "The regions that govern impulse control... continue to mature..." — relative clause + which leaves younger children unusually vulnerable 是文法 range 展示。
  • 句 5 (Evidence): "A 2023 Stanford study of over 4,000 pre-teens found that..." — 機構、年代、樣本數、具體後果。
  • 句 6 (Link): "Such evidence suggests that... a measurable protective measure." — 把證據升級成政策理由。

§3 — 第二個理由 + Concession

  • 句 7 (Topic sentence): "A further consideration is the erosion of unstructured social time." — 第二個獨立角度。
  • 句 8 (Develop): "...processes that smartphones compress into shallow, screen-mediated exchanges." — compress into 是 Band 7 動詞選擇。
  • 句 9 (Concession): "Admittedly, a blanket ban risks isolating children..." — 承認反方 + which is why I favour a calibrated policy 反向回扣立場。
  • 句 10 (Nuanced position): "Restricting smartphones while allowing basic phones..." — 具體 policy compromise。

§4 — Conclusion

  • 句 11 (Restate with nuance): "...though I regard the design of the policy as equally important." — 呼應 intro 的 qualification。
  • 句 12 (Forward-looking): "...the default setting for childhood should be less, not more, exposure..." — 濃縮理由 + 記憶點。

四大評分項證據表

| 評分項 | 本篇證據 | Band | |--------------------|----------------------------------------------------------------------------------------------------------------------|------| | Task Response | 立場明確（broadly support, agree with the age limit）；兩個理由各自發展；承認反方並調整立場而非推翻；結論一致 | 7 | | Coherence & Cohesion | 段落功能分明；linker 多樣（A further consideration, Admittedly, which is why, Given what）；referent 清楚 | 7 | | Lexical Resource | Topic-specific（dopamine-driven design, screen-mediated, calibrated policy, blanket ban）；無重複 | 7 | | Grammar Range | Passive（be enforced, is engineered）；relative clause（that govern, that smartphones compress into）；conditional-like（would preserve）；cleft（how the restriction is enforced matters） | 7 |

三個你可以複製的動作

1. 「broadly agree + qualification」寫法

不要寫極端立場（I completely agree）——IELTS 給 Band 7+ 最愛有層次的立場。公式："I broadly agree with X, although I would argue that Y"——一句話兩個 Task Response 加分點。

2. §3 用「concession 轉回立場」

句 9-10 的模型值得背："Admittedly, [反方]. [連接詞], I favour a calibrated [立場] rather than outright [反方]." ——承認反方後不放棄立場，而是更精細化。

3. 「measurable X not arbitrary Y」對比

句 6 的 "not an arbitrary precaution but a measurable protective measure" 是 Band 7+ 的經典手法——用 A-not-B 結構強調立場合理。可以改造成 "not a luxury but a necessity / not a temporary fix but a structural reform"。
