问题     Spanning the ocean divide between the U.S. and Russia, it is one of the richest and most commercially productive marine environments on earth, teeming with pollack and halibut, fur seals and Steller’s sea lions, puffins and murres. The seals and seabirds depend on catching fish, and so do humans. More than 2,000 boats from the U.S., Russia, Japan, Norway, China, Poland and the Koreas haul in an annual catch worth roughly $1 billion. The portion taken off the shores of Alaska alone amounts to one-half the sea life caught by commercial fishing vessels in U.S. waters.
    But will the bounty last? Since the majority of the world’s fisheries are in a state of collapse, as too many boats chase too few fish, conservationists fear the same fate for the Bering Sea, the last great refuge of marine abundance. Competition among countries for the rights to fish certain sectors of the sea is already fierce and could turn violent, as it has elsewhere in the world. The Russians have severely depleted fish stocks in their zone, and the international area open to all boats, called the Doughnut Hole, has been nearly stripped of commercial fish.
    No species is more important to man and beast than pollack, the No. 1 ingredient of frozen fish sticks and the fish items served by chains like Burger King and Long John Silver. Each year the Bering Sea yields two billion kg of this bottom-dwelling creature, making me pollack business the biggest fish harvest in the world.
    On the surface, that business is healmy: the pollack catch has stayed near record levels. But signs of overfishing and an ailing ecosystem can be seen higher up in the food chain. The fur-seal population has not increased despite a long-standing ban on commercial hunting. The number of Steller’s sea lions, which feed mostly on pollack, has plunged 80% in the past years, and seabirds such as the red-legged kittiwake are also in trouble.
    Even if fishing is brought under control, the Bering Sea faces threats that originate thousands of miles away. Wind currents from industrial areas far to me south bring in pollutants like insecticides and heavy metals, which collect in me tissues of wild life and the local Inuit people. At the same time the region has been warming up, and part of me reason may be the buildup of greenhouse gases in the atmosphere. Whatever the cause, sea ice has been retreating farther to the north, making life harder for polar bears and other ice-dwelling animals. [br] What is true about the marine creatures in the Bering Sea?
选项 A、Russia tries to save the sea by stocking fewer fish.
B、There are still abundant marine creatures there.
C、It will soon be stripped of commercial fish.
D、There are too many boats but too few fish.
答案 B
解析 根据题干中的Bering Sea定位到第2段第2句。该句末尾用于修饰Bering Sea的后置定语表明白令海峡现在仍然有abundant marine，因此B正确。C中的will soon说的过于绝对了，原文只是有这种担心，但没有提到“什么时候”白令海峡的鱼都会被打光：D与第2段第2句中as引出的从句一模一样，但该从句讲的是全世界范围的普遍情况，而不是白令海峡的情况。
