About 3 billion people live within 100 miles (160km) of the sea, a number that could double in the next decade as humans flock to coastal cities. The oceans produce $3 trillion of goods and services each year and untold【C1】________for the Earth’s ecology. Life could not exist【C2】________these vast water reserves—and, if anything, they are becoming even more important to humans than before.
Mining is about to begin under the seabed in the high seas. New summer shipping lanes are opening【C3】________ the Arctic Ocean. The genetic resources of marine life promise a big【C4】________: the number of patents has been rising at 12% a year.
But these developments are【C5】________compared with vaster forces reshaping the Earth, both on land and at sea. It has long been clear that people are damaging the oceans—【C6】________the melting of the Arctic ice in summer and the death of marine lives. Now, the【C7】________ of that damage are starting to be felt onshore.
Thailand provides a【C8】________example. In the 1990s it cleared coastal plants to set up fish farms. Ocean storm surges in 2011, no longer【C9】________by the plants, rushed in to【C10】________the country’s industrial heartland, causing billions of dollars of damage.
More【C11】________is the global mismanagement of fish stocks. About 3 billion people get a fifth of their protein from fish, making it a more important protein source than beef.【C12】________a vicious cycle has developed as fish stocks decline and fishermen【C13】________to grab what they can of the remainder.【C14】________the Food and Agriculture Organization, a third of fish stocks in the oceans are over-exploited. People could be eating much better, were fishing stocks【C15】________ managed.
The forests are often called the lungs of the Earth, but the description better fits the oceans. They produce half the world’s【C16】________of oxygen. At the moment, the oceans are moderating the【C17】________of global warming— though that may not【C18】________. This cannot be good news,【C19】________scientists are still debating the likely consequences.【C20】________, the decades of damage imposed on the oceans are now damaging the environment on land.
【C2】
选项
A、in
B、without
C、for
D、outside
答案
B
解析
后半句提到海洋对人类来说更是前所未有地重要(even more important…than before)。B项without意为“没有”,没有这片巨大的水域就没有生命,可以显示出海洋的重要性。A项in“在……里面”,在这片巨大的水域里生命无法存在,不符合事实。C项for“因为”,生命不可能因为这片海域而无法生存。D项outside“在……之外”,生命在海洋外面无法生存,事实上很多生命在海洋之外生存。
