Task 2 寫「政府努力做某事」、Speaking Part 3 寫「人類的努力」時，考生最常寫 try / try hard——口語、平淡。學術升級：endeavour。
字義
- Endeavour (v.) — to make a serious or determined effort to do something.
- Endeavour (n.) — an attempt or effort to achieve something, often something significant.
英式拼法 endeavour；美式 endeavor——IELTS 兩個都接受，建議統一英式。
5 個 Band 7+ 例句
- The new administration has endeavoured to restore public trust through greater transparency.
- Scientists endeavour to understand phenomena that may take generations to fully explain.
- Space exploration is one of the most ambitious human endeavours of the modern era.
- Universities should endeavour to make scholarships more widely available.
- Despite our best endeavours, the deadline proved impossible to meet.
常見錯誤
句型固定（動詞）：endeavour to + 動詞原形。別寫 endeavour doing。
- Schools should endeavour to engage every student. ✓
搭配名詞用法：human endeavour / scientific endeavour / a noble endeavour / our best endeavours。
Register 偏正式書面：Speaking Part 1 用 I endeavour to study every day 像在寫履歷——不自然。Part 3 與 Task 2 才用。
過度使用：一篇 Task 2 用一次最有效——太多會像在背字典。
同等級替換（Band 7+）
- Strive — We must strive to balance growth with sustainability.（更動感）
- Seek to + V — Reformers seek to widen access to higher education.（最安全、最書面）
試試看
下次 Task 2 政策段，把 governments try to 換成 governments endeavour to——一個字告訴考官你語感成熟。
