What can be inferred from the world population? [br]
In the 20th century the planet’s population doubled twice. It will not double even once in the current century, because birth rates in much of the world have declined steeply. But the number of people over 65 is set to double within just 25 years. This shift in the structure of the population is not as momentous as the expansion that came before. The author Fred Pearce claims it is possible that half of all the humans who have ever been over 65 are alive today. But as a share of the total population, at 8% , it is not that different to what it was a few decades ago. By 2035, however, more than 1. 1 billion people — 13% of the population — will be above the age of 65. This is a natural corollary of the dropping birth rates that are slowing overall population growth; they mean there are proportionally fewer young people around. The "old-age dependency ratio" — the ratio of old people to those of working age — will grow even faster. In 2010 the world had 16 people aged 65 and over for every 100 adults between the ages of 25 and 64, almost the same ratio it had in 1980. By 2035 the UN expects that number to have risen to 26. In rich countries it will be much higher. Japan will have 69 old people for every 100 of working age by 2035 (up from 43 in 2010) , Germany 66 (from 38). Even America, which has a relatively high fertility rate, will see its old-age dependency rate rise by more than 70% , to 44. Developing countries, where today’s ratio is much lower, will not see absolute levels rise that high; but the proportional growth will be higher. Over the same time period the old-age dependency rate in China will more than double from 15 to 36. Latin America will see a shift from 14 to 27.
选项
A、The average ratio of the world was 16% in 2010.
B、The ratio has changed greatly from 1980 to 2010.
C、The ratio in Japan was 43% in 2010.
D、The ratio in Germany was 38% in 2010.
答案
B
解析
从文中“…almost the same ratio it had in 1980”可以看出,从1980到2010这个比率基本上没有变化。因此,选项B的叙述与原文大意不符。
