问题    Aging poses a serious challenge to OECD (Organization of Economic Co-operation and Development) countries, in particular, how to pay for future public pension liabilities. And early retirement places an【C1】______burden on pension financing. There is no easy solution, but【C2】______retirement could help.
   Early retirement may seem like a【C3】______individual goal, but it is a socially expensive one, and makes the present public pension system difficult to sustain for long. The【C4】______reason is that more people are retiring early and living longer. That means more retirees depending on the funding of those in work for their【C5】______, The【C6】______is worrying. In the next 50 years, low fertility rates and rising life expectancy in OECD countries will cause this old-age dependency rate to roughly double in size. Public pension payments, which【C7】______30c80 % of total retirement incomes in OECD countries, are【C8】______to rise, on average, by over three percentage points in GDP and by as much as eight percentage points in some countries.
   【C9】______is the pressure on pension funds that there is a danger of today’s workers not getting the pensions they expected or felt they【C10】______for.
   Action is needed,【C11】______simply aiming to reduce the【C12】______(and cost) of public pensions, or trying to【C13】______the role of privately funded pensions within the system, though necessary steps, may be【C14】______to deal with the dependency challenge. After years of
   【C15】______early retirement schemes to avoid【C16】______and higher unemployment, many governments are now looking【C17】______persuading people to stay in work until they are older.【C18】______, the thinking goes, if we are healthier now and jobs are physically less【C19】______and unemployment is down, then perhaps the【C20】______rate should rise a new.
【C4】
选项 A、controversial
B、superficial
C、trivial
D、essential
答案D
解析 本题考查形容词词义辨析。controversial意为“有争议的”；superficial意为“肤浅的，粗略的”；trivial意为“不重要的，琐碎的”；essential意为“本质的，基本的”。联系上文，空格所在的句子的意思应是：“更多的人提早退休而寿命又更长”是“当前的公共养老金系统难以持久”的……原因。略读全文可知，下文都在论述这一原因，可见它是很重要的，因此D选项为正确答案。
