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] 【C2】
选项
答案
E
解析
从语法结构看,这里缺少表语成分,选项中符合这一要求的词语有A)falling, G)exceeding, L)hard, H)different, I) threatened, E)reached和O)started。从句意来看,空格所在句指出虽然人口数量仍在增长,但是一个拐点似乎已经……了,该空填入的词应和非生物名词point搭配,如果是动词,则应和point形成逻辑上的主谓或动宾关系,因此reached是符合语境。
