English Senior High over 2 yearsago expectancyがどのように訳されているのか分からないです。解説お願いします。 42020年度 英語 [名産] 英語 P 問題 Ⅰ 以下の文章を読み、下の問いに答えなさい。 29 (120分) 〈前期〉 Asia is aging fast: by 2040, 16 percent of the region's population will be older than 65, more than double the 7.8 percent share in 2015. While the rise in healthy life expectancy is a positive development, this demographic shift (1) Gener poses a serious threat to many economies, which are already losing vitality. A consistent supply of young, skilled workers was an essential factor of Asia's rapid economic catch-up process over the last three decades. That process is now over, and middle-income countries like China and Vietnam are now facing accelerating population aging. In South Korea, the working-age population (15-64 years) will shrink (7) 10 percent from 2017 to 2030. most as exp wit ab to Resolved Answers: 1
