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. [br] Which of the following is not true according to the passage?
选项
A、Human population expands at an exponential rate.
B、Population growth has shown fluctuation in demographic history.
C、Population growth can not be regarded as a social failure.
D、Increase in population is related to productivity.
答案
A
解析
从本文我们知道,人口增长并不是直线增长而是有波动,每次增长都是在生产力水平提高后出现,随后又降下来趋于稳定,人口增长被认为是代表经济进步和人类的胜利。A.人类人口直线膨胀,这显然与本文不符;B.人口统计史表明人口增长出现波动;C.不能把人口增长看做是社会的失败;D.人口增加与生产力相关。B、C、D均与本文相符。
