The problem is emphasized by the fact that the decline in numbers happened in less than twenty years.Deep-sea fish take a long time to reproduce and normally live for many years. 3 The average size of such fish also declined，with one species showing a 57 percent decline in average size.This is of particular concern，as large fish tend to produce more offspring than small ones. 4 The deep-sea species have been caught as if they were the fast-breeding(快速繁殖) fish like sardine and herring.It is like killing elephants as if they reproduced at the same rate as rabbits. The damage done by overfishing goes beyond the sea environment.Millions of people make a living in the fishing industry. 5 Measures must be taken to not only conserve ecosystems，but also sustain livelihoods and ensure food security. A．Billions of people rely on fish for protein. B．Many people now choose not to eat deep-sea fish. C．Unfortunately，their reproduction rate is very low. D．This puts them in the category of “critically endangered”． E．None of these facts has been taken into account by the fishing industry. F．Overfishing is a major cause of decline in populations of ocean wildlife. G．This has resulted in a sharp decline in the numbers of many of the species caught. 语篇解读　这是一篇说明文。短文介绍了由于过度捕捞，浅水鱼类的数量已经严重下降，以及由此导致的后果。 1．答案　G 解析　根据空前一句可推知，空处应承接上文说明以上做法导致的不良影响。故G选项“这导致许多被捕获物种的数量急剧下降”切题。故选G。 2．答案　D 解析　根据空前一句可知，数量下降到了一定程度，已经接近灭绝。故D选项“这使得它们被归为‘极度濒危’物种”切题，This指代上文提到的“numbers have declined by between 87 percent and 98 percent”。故选D。 3．答案　C 解析　根据空前一句和空后两句可知，空处应承接上下文说明深海鱼类的繁殖率非常低。故C选项“不幸的是，它们的繁殖率非常低”切题。故选C。 4．答案　E 解析　根据空后两句可知，渔业忽略了一些物种繁殖速度慢的事实。故E选项“渔业没有考虑到这些事实”切题。故选E。 5．答案　A 解析　根据空前一句可知，空处与上文为并列关系，说明渔业对人的重要作用。故A选项“数十亿人依赖鱼类获取蛋白质”切题。故选A。 学科网（北京）股份有限公司 $$
