    Sea rise as a result of global warming would immediately threaten that large fraction of the globe living at sea level. Nearly one-third of all human beings live within 36 miles of a coastline.
    Most of the world’s great seaport cities would be【C1】________. Some countries would be inundated.
    Heavily populated coastal areas where large populations occupy low-lying areas, would suffer extreme dislocation.
    Warmer oceans would spawn stronger hurricanes and typhoons,【C2】________ coastal flooding, possibly swamping valuable agricultural lands around the world. Reduced water quality may result as【C3】________ flooding which forces salt water into coastal irrigation and drinking water supplies, and irreplaceable, natural forest could be flooded with ocean water destroying forever many of the【C4】________plant and animal species living there.
    Food supplies and forests would be【C5】________ affected. Changes in rainfall patterns would disrupt agriculture. Warmer temperatures would【C6】________ grain-growing regions polewards. The warming would also increase and change the pest plants, such as weeds and the insects attacking the crops.
    Human health would also be affected. Warming could【C7】________ tropical climate bringing with it yellow fever and other diseases. The harmful effects of localized urban air pollution would very likely be more serious in warmer conditions. There will be some【C8】________ from warming. New sea-lanes will open in the Arctic, longer growing seasons further north will create new agricultural lands, and warmer temperature will make some of today’s colder regions more habitable. But these benefits will be in individual areas. The natural systems—both plant and animal—will be less able than man to cope and【C9】________. Any change of temperature, rainfall, and sea level of the magnitude now anticipated will be destructive to natural systems and living things and【C10】________ to man as well.
【C6】
选项
答案H
解析 空格前的would提示空格处应填动词原形。上一句提到“降雨模式的改变将破坏农业的发展”，由此判断本句表达的大意是“气温的升高将会对粮食生产区域产生影响”，即这些区域会发生变化。再结合句末表方向的副词polewards“向南(北)极”，可进一步推断这种变化应该是指位置的改变，因此选shift“使转移”。
