保留句型骨架，替換關鍵詞練習其他議題：

肥胖 → 成癮：

  • obesity epidemic → opioid crisis
  • sugar taxes → harm reduction programs
  • food deserts → treatment deserts
  • ultra-processed foods → overprescribed painkillers

肥胖 → 氣候變遷：

  • sedentary lifestyles → car-dependent cities
  • sugar consumption → fossil fuel consumption
  • school nutrition standards → building efficiency codes
