问题      For thousands of years, the number of people in the world inched up. Then there was a【C1】______ spurt (爆发) during the industrial revolution which produced, between 1900 and 2000, a near-quadrupling of the world’s population.
     Numbers are still growing; but recently an inflection (变形) point seems to have been【C2】______ . The rate of population increase began to slow. Women【C3】______ having fewer children than the number required to keep populations stable. Last year the United Nations estimated the world’s average【C4】______ would fall below replacement by 2025. Demographers expect the global population to peak at around 10 billion by mid-century.
     As population predictions have changed in the past few years, so have attitudes. The【C5】______   about resource constraints that prevailed during the 1970s and 1980s, when the population was rising【C6】______ ,has given way to a new concern: the number of people in the world is likely to start【C7】______ .
    Some regard this as a cause for【C8】______ on the ground that there are obviously too many people on the planet. But there doesn’t seem to be much danger of a Malthusian catastrophe. Mankind appropriates about a quarter of the net primary production of the Earth-a lot, but hardly near the point of【C9】______ . Nor does the opposite problem-that the population will fall so fast that civilization is【C10】______ -seem a real danger. The projections suggest a flattening off and then a slight decline in the foreseeable future.
   A) falling                      F) decision                    K) panic
   B) exhaustion                   G) exceeding                   L) hard
   C) steeply                      H) different                   M) highly
   D) fertility                    I) threatened                  N ) celebration
   E) reached                      J) sudden                      O) started [br] 【C9】
选项
答案 B
解析 从语法结构看，该空应填入一个名词，选项中符合要求的词有B)exhaustion, F)decision。从句意来看，空格所在句指出人类挪用了地球净生产量的四分之一，尽管很多，但是离……之日甚远，由but hardly可知填入词应与资源消耗有关且具有贬义色彩，故exhaustion最符合语境。
