高齡化題是 Part 3 近年越來越頻繁——特別是在東亞考區。台灣考生對「老人很多」有直觀感受，但很少思考政策與社會影響。Band 7 的答案要能連到勞動力、醫療成本、跨世代公平。

5 題代表題 + Band 7+ 範例
Q1. Why are populations ageing in so many countries?
Two trends are converging. Generally speaking, people are living considerably longer thanks to better healthcare and nutrition, which is unambiguously good. At the same time, birth rates have fallen dramatically, particularly in East Asia — Taiwan's total fertility rate is around 0.9, well below replacement. So the pyramid is flipping: more elderly, fewer young, rapidly.
Q2. What are the main challenges of an ageing society?
I'd say three main pressures. First, healthcare costs rise sharply — older patients are simply more expensive to treat. Second, the labour force shrinks relative to the retired population, which squeezes tax revenue and pension systems. Third, arguably the most underestimated, is social: loneliness among elderly people becomes a serious public-health issue in its own right.
Q3. Should the retirement age be raised?
On the whole I'd say it probably has to be, though it's politically painful. When pension systems were designed, life expectancy was around 70; it's now approaching 85 in developed economies, so the maths simply doesn't work at the old retirement age. That said, raising it uniformly is unfair — a construction worker and an office worker have very different capacities at 65, so flexibility matters.
Q4. Is it fair to ask young workers to support a growing elderly population?
It's a genuinely difficult question. Intergenerational solidarity has always been the basis of pension systems — today's workers fund today's retirees, on the understanding the next generation will do the same. On the other hand, if the ratio keeps tilting, that implicit contract breaks down. So the honest answer is: fair in principle, but the current numbers stretch fairness to breaking point.
Q5. How might society need to change to cope with ageing?
Broadly speaking, in three ways. Workplaces need to adapt to older employees — flexible hours, phased retirement, ongoing training. Cities need to become more age-friendly — seating, accessible transport, walkable streets. And culturally, arguably, we need to stop treating ageing as decline and start recognising older people as active participants, not just dependants.

台灣考生常見陷阱：一邊倒向悲觀
"Ageing is a big problem. Taiwan will collapse. Government must do something." ——典型的一邊倒悲觀 Band 6 答法。Band 7 要能同時承認挑戰，並看見可能的調整路徑。
修正：加入「另一面」視角：
An ageing population does create genuine fiscal pressure, and I wouldn't downplay that. On the other hand, older societies aren't automatically stagnant — Japan has managed three decades of ageing without social collapse, largely through phased retirement, robot-assisted care, and active older workers. So the challenge is real, but not existential.
