The concept of obtaining fresh water from icebergs that are towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life. But now it is being【C1】______ quite seriously by many nations, especially since scientists have warned that the human race will【C2】______ its fresh water supply faster than it runs out of food.
Glaciers are a possible【C3】______ of fresh water that has been overlooked until recently. Throe-quarters of the Earth’s fresh water supply is still tied up in glacial ice, a reservoir of【C4】______ fresh water so immense that it could【C5】______ all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10,000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica.
Huge glaciers that【C6】______ over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes, rather, they are formed【C7】______ on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction【C8】______ to the wind, palled by subsurface currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean. To control them and【C9】______ them to parts of the world where they are needed would not be too difficult.
The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling(传送) of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalinization (脱盐) , or【C10】______ salt from water.
A) removing F) resource K) similar
B) stretch G) outgrow L) source
C) deriving H) opposite M) ensured
D) entirely I) approximately N) sustain
E) untapped J) considered O) steer [br] 【C2】
选项
答案
G
解析
此处需要及物动词原形作谓语。本句对比人类对淡水的需求和对食物的需求,根据本句的对比成分faster than it runs out of food,可知该谓语动词意义上与run out of(用尽)相近。显然,词库中的动词原形只有outgrow在意义、用法与形式上都符合。
