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. [br] 【C8】
选项
A、related
B、relative
C、proper
D、reasonable
答案
B
解析
形容词辨析题。句意为:调查记录也包括水温信息、溶液中含盐量的相对比例和溶于水中的氧气量。[B]relative“相对的”,可以和proportion搭配,意为“相对比例”,故为答案。[A]related“相关的,有联系的”;[C]proper“适当的”;[D]reasonable“合理的”,均不符合句意,故排除。
