问题    For thousands of years, the number of people in the world inched up. Then there was a【S1】   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【S2】 . The rate of population increase began to slow. Women 【S3】 having fewer children than the number required to keep populations stable. Last year the United Nations estimated the world’s average【S4】  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【S5】  about resource constraints that prevailed during the 1970s and 1980s, when the population was rising【S6】,has given way to a new concern: the number of people in the world is likely to start  【S7】.
   Some regard this as a cause for【S8】 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【S9】 . Nor does the opposite problem-that the population will fall so fast that civilization is【S10】 -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
选项
答案 J
解析 从语法结构看，该空应填入一个形容词修饰spurt，选项中符合这一要求的词有L)hard，J)sudden，H) different和K)panic。前一句提到上千年来世界人口一直保持着缓慢增长，空格所在句则提到，工业革命时期世界人口出现了一次……的爆发，以至于从1900年到2000年增长了近四倍，由此可知，人口数量经历了一次陡增的过程，因此sudden最符合语境。
