问题     The news about the world’s oceans in 2003 wasn’t that they’re in trouble — that much was already clear — but that the scale of devastation is far greater than anyone had realized. A shocking study revealed that a full 90 percent of the species most desirable to fishmongers(鱼商)—tuna, halibut, sharks, swordfish, grouper — has been wiped out in the past half century.

    But there was hopeful news as well. An alternative to conventional fishing practices, while not a cure-all(万灵药), could significantly restore ravaged fish populations.
    The chilling centerpiece of last year’s marine research: just 50 years of industrial fishing has decimated(大批杀害)the world’s large predator(食肉动物)fish species, according to a report published in Nature in May. Irresponsible fishing practices have resulted severe casualties: Shrimp trawling(拖网捕捞)in the Gulf of Mexico, for example, a reckless process in which, for every ton of shrimp obtained, three tons of fin-fish(长须鲸)are destroyed and discarded — has shrunk large fish stocks a thousandfold. "Across the board we’ve removed everything bigger than a bicycle from the o-cean," says Steve Palumbi, a Stanford University biologist, "and that has almost certainly changed the ocean in fundamental ways. "
    But the urgent need for large-scale conservation efforts is on a collision course with economic pressures to expand fishing even further, according to a 2003 report by the Pew Oceans Commission, an independent expert panel, as well as preliminary reports from members of the Bush-appointed U. S. commission on Ocean Policy. Americans are eating more seafood than ever: Consumption was up 7 percent in 2002, to 4. 5 billion pounds. Worldwide, more than 130 billion pounds of marine species are caught annually, and that doesn’t include the huge amount of sea life destroyed as by-catch. More than a billion people rely on fish for protein. " We need to change the whole ethic of how we are viewing the oceans," says Andrew Rosenberg, a member of the Commission on Ocean Policy, " from a place that we use to a place we care for. "
    In September marine biologists Fiona Gell and Callum Roberts of the University of York in England offered a solution, boldly asserting that at least 30 percent of the world’s ocean habitat had to become safe zones for marine life. It’s a practical, not a sentimental matter, they contend. After studying 60 no-fishing zones around the world, Gell and Roberts discovered that the fish there live longer, grow larger, and produce more young than those in unprotected areas. Significantly, as populations growing, many fish head into less crowded areas outside the reserve, where fishermen reap the benefits indefinitely. "It’s a no-brainer(无需用脑的事), really, isn’t it?" Roberts observes. "Like money in the bank producing interest. " [br] What’s the news about the oceans in 2003?
选项 A、People ignore what the oceans are suffering.
B、The scale of the ocean devastation is out of our expectation.
C、The fishmongers are making effort to improve their fishing practices.
D、The oceans are losing many rare species.
答案 B
解析 事实细节题。第一段首句用了一个not…but句型，重点在but后面，指出2003年有关海洋的消息，不是海洋处于危险的境地，而是其破坏程度远比任何人已经意识到的还要严重。由此看出海洋受到破坏的程度超过了人们的预料，[B]项正确。人们不是忽视了而是低估了海洋的受破坏的程度，[A]项错误。[C]项文中未提及，[D]项是程度严重的一个方面，不能概括2003年一年的内容，故也排除。
