科技（Technology）是 IELTS Task 2 近五年上升最快的主題。AI、演算法、資料隱私、假訊息——這些議題已經從「選修」變成「必考」。
但這個主題也是詞彙陷阱最多的：大部分考生只會 technology, computer, internet, phone，寫一整段 essay 下來彷彿停在 2005 年。Band 7+ 需要的是 2024 年的科技語彙——algorithm bias, data breach, tech-savvy, information overload。
先看 Band 6 → 7 詞彙升級 與 Academic Collocations。
這個主題為什麼特別考驗詞彙
IELTS 科技題沒有中間值：你知道 algorithm / surveillance / misinformation 就能寫出 Band 7 的論點；不知道只能寫 some people use phones too much——Band 5 的模樣。
背這篇的 25 個字——比練 10 篇 essay 的投報率都高。

題目脈絡：Some believe social media has done more harm than good.
The verdict on social media depends heavily on which outcome we prioritise. On one level, these platforms have delivered genuine connectivity: families separated by migration can now share daily life, and marginalised voices can reach audiences that traditional media ignored. Yet the same algorithm-driven architecture that amplifies connection also fuels misinformation, attention fragmentation, and a mental-health crisis among adolescents. Recent studies indicate that teenagers exposed to over four hours of daily screen time are twice as likely to report clinical anxiety. Compounding this, routine data breaches have eroded public confidence in how personal information is handled, while algorithm bias quietly shapes which opinions users ever encounter. On balance, I would argue the harm is not inherent to the technology but to its unregulated design — and until governments treat data privacy and algorithmic transparency as enforceable rights, the damage is likely to outweigh the gains.
