51. What does the passage say is the more recent thinking of economic growth?
- A. It should be made sustainable.
- B. It is vital to the future of humanity.
- C. It should be governments' chief concern.
- D. It is an indicator of government performance.
答案：B
答案句：GDP growth is not a good indicator of how well a country is performing, and should not be the primary goal of governments. Unlimited growth is not sustainable, and economic thinking is moving toward the idea that we should aim for sustainability in our economic models. But while a sustainable economy is vital to our future, it is a means to an end, not an end in itself.
参考译文：GDP增长并不是衡量一个国家表现好坏的好指标，也不应成为政府的主要目标。无限的增长是不可持续的，经济思维正转向我们应该在经济模式中追求可持续性的理念。但虽然可持续经济对我们的未来至关重要，它是达到目的的手段，而非目的本身。
定位线索：题干“more recent thinking of economic growth”→答案句“economic thinking is moving toward the idea that we should aim for sustainability”；文中“sustainable economy is vital to our future”对应选项B“It is vital to the future of humanity”。
解析：题干问关于经济增长的较新思考，答案句明确指出经济思维正转向追求可持续性，且可持续经济对未来至关重要，直接对应选项B。选项A“应使其可持续”是文中提到的目标，但题干问的是“more recent thinking”，即新思维的内容，而非建议；选项C与原文“should not be the primary goal”矛盾；选项D是原文否定的观点。
54. Why does the WHO feel the need to appeal to the economic benefits of improving mental health to justify its recommendations?
- A. Mental health programs cannot be executed without GDP growth.
- B. Psychological interventions are conducive to people's wellbeing.
- C. Poor mental health is detrimental to a nation's economic system.
- D. Governments still take economic development as their priority.
答案：D
答案句：It says a lot, however, that the WHO feels the need to appeal to the economic benefits of improving mental health to persuade governments that the cost of taking proposed measures is justified. As long as the economy is their priority, governments need go no further than ensuring citizens' continued productivity.
参考译文：然而，WHO觉得有必要诉诸改善心理健康的经济利益来说服政府，证明采取建议措施的成本是合理的，这很能说明问题。只要经济仍是政府的优先事项，政府就无需超越确保公民持续生产力的范畴。
定位线索：题干“Why does the WHO feel the need to appeal to the economic benefits”→答案句“the WHO feels the need to appeal to the economic benefits”；文中“As long as the economy is their priority”对应选项D“Governments still take economic development as their priority”。
解析：题干问WHO为何诉诸经济利益，答案句后半句解释原因：只要经济是政府优先事项，政府只关心生产力，因此WHO必须用经济利益说服政府，对应选项D。选项A“没有GDP增长无法执行”文中未提；选项B“心理干预有益健康”是WHO建议的内容，非原因；选项C“心理健康差损害经济”是WHO诉诸经济利益的隐含前提，但非直接原因。
