替換任務

保留句型骨架，替換關鍵詞練習其他議題：

睡眠剝奪 → 數位成癮：

sleep deprivation → digital addiction
screen time before bed → constant connectivity
melatonin production → dopamine regulation
work-life balance → digital wellbeing

睡眠剝奪 → 工作倦怠：

chronic sleep loss → chronic stress
blue light exposure → constant availability
sleep schedules → recovery time
workplace cultures → hustle culture
