Seafood could be going off a lot of menus as the world warms. More than half of a group of fish【C1】______ for the marine food web might die if, as 【C2】______, global warming reduces the amount of oxygen【C3】______ in some critical areas of the ocean—including some of our richest fisheries.
The prediction【C4】______a unique set of records that goes back to 1951. California has regularly【C5】______ its baby fish to support the sardine fishery. "There is almost no other dataset going back so far that【C6】______every kind of fish," says Tony Koslow of the Scripps Institution of Oceanography in La Jolla, California, who heads the survey. The survey records also include information 【C7】______ water temperature, the 【C8】______proportion of salt in a solution and the dissolved oxygen content.
Koslow’s team studied records of 86 fish species found【C9】______ in the samples and discovered that the abundance of 27 of them【C10】______ strongly with the amount of oxygen 200 to 400 metres down; a 20 percent drop in oxygen meant a 63 percent drop in the fish. There have been several【C11】______of low oxygen during the period【C12】______, mainly in the 1950s and since 1984. Global climate models predict that 20 to 40 percent of the oxygen at these depths will disappear over the next century 【C13】______ wanning, says Koslow— mainly because these waters get oxygen by mixing with【C14】______ waters. Warmer, lighter surface waters are less likely to mix with the colder, denser waters【C15】______.
Of the 27 species most【C16】______ by low oxygen, says Koslow, 24 were fish that spend the daytime in deep, dark waters below 200 metres to【C17】______ predators that hunt by【C18】______. There are 10 billion tonnes of fish globally—10 times the annual global commercial【C19】______—and they are a vital food for other fish and【C20】______ birds and mammals.
【C9】
选项
A、continually
B、endlessly
C、consistently
D、steadily
答案
C
解析
副词辨析题。句意为:克斯罗研究团队对86种鱼类所做的研究一致显示,其中27种鱼类的数量与水下200—400米的水中含氧量密切相关。根据上下文可以看出,本句强调研究结果的一致性,以说明研究结果是极具说服力的。四个选项中,[A]continually“不断地,频繁地”,强调动作的反复性;[B]endlessly“不断地,无穷尽地”,强调动作的无止境;[C]consistently“一贯地,一致地”,强调统一性、一致性;[D]steadily“稳定地,稳固地”。因此[C]为答案。
