最近读了新平行阅读法，有些题目还是不太懂，网络上也找不到，希望可以在这里问问
F) The future, we are told, is likely to be different. Detailed surveys
of social and economic trends in the European community show that
Europe's population is falling and getting older, The birth rate in the
Community is now only three-quarters of the level needed to ensure replacement
of the existing population. By the year 2020, it is predicted that more than
one in four Europeans will be aged 60 or more and barely one in five will be
under 20. In a five-year period between 1983 and 1988 the Community's female
workforce grew by almost six million. As a result, 51% of all women aged 14
to 64 are now economically active in the labour market compared with 78% of
men.
题目: In the future, the number of people in employable age groups will
decline.
答案: Yes
解析大意是说:研究显示欧洲人口数量下降且老龄化。现有出生率仅能替代目前人口3/4。
代表将来达到工作年龄人口数量就是下降了
但我疑惑的地方是，就业年龄族群会往上下延伸，年龄级距变大，(by the yr 2020那句)
这不就是拿来弥补人口数的不足吗?总体来讲就业人口数量应该没变阿@@
还有发现这本书的P160那篇没有全部答案耶，请问有人有吗?
谢谢大家

重点可能在前段，提示=The future...+ birth rate in... replacement of the existing populBy 说的是 超过1/4大于60岁,少于1/5 小于20岁

喔~因为By那句只提到就业年龄变化，没有提到数量，所以不可像我之前那样推论。 谢谢S大!!
