The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleo-ecologist Edward Deevey, the past million years show three momentous changes. The first, a rapid increase in population around one million B, C, followed the innovations of tool-making and tool-using. But when the new power from the use of tools had been exploited, the rate of world population growth fell and became almost stable.
The next rapid jump in population started perhaps 10,000 years ago, when men began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated.
These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down when, or if technology begins to yield fewer innovations. Of course, the current knowledge revolution may continue without foreseeable end. Either way contrary to popular belief in constant geometric growth-population can be expected in the long run to adjust to productivity. And when one takes this view, population growth is seen to represent economic progress and human triumph rather than social failure.
What can be concluded when the current tide of knowledge revolution ebbs?
选项
A、Productivity will rise.
B、Productivity will receive no impact.
C、Population growth will slow down.
D、Population growth will become accelerated.
答案
C
解析
从人口前三次的重大变化中我们知道每次人口增长后又开始下降趋于稳定,当前人类处于知识爆炸时代,科学技术日新月异。如果这一潮流下降的话,那么可以推断人口增长会慢下来,所以正确答案为C;A.生产力将会增长;B.生产力将不会受到影响;D.人口增长将会加快。很显然 A、B、D均与本文不符。
