Narrator
Listen to part of a lecture about the environment study in Biramichi River.
Professor
Good morning everyone. First of all I’d like to thank Professor Johnson for giving me the opportunity to talk to you about my research on fishing in Biramichi River. Well, in a world today of immense technology, increasing population and flourishing economies, investigations have shown that the global economy is outgrowing the earth’s ecosystems. The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance.
    There are some serious problems in the Biramichi River. The local Chamber of Commerce, which represents the industries in the area, hired me as a consultant to do a one-year study on fishing in the Biramichi River and write a report for them. This is my report.
    One of the major problems in the Biramichi River, is that the level of the oxygen in the water is too low. Several chemicals have displaced the oxygen. This chemical pollution has two sources: the factories which dump polluted water directly into the river, and the local community, which dumps untreated human waste into the river. The local town government has already spent 2 million dollars on waste water treatment projects. But it would cost another 27 million to complete the projects. It would take at least 15 years for the town to collect enough revenue from taxes to complete these projects. The factories here employed 17 000 people, and in the area where there is very little alternative employment, it is not economically practical to close or relocate the factories. Also, the factories can not afford to finance chemical treatment plants by themselves.
    Another problem is that the members of the Biramichi fishing cooperative are over-fishing. Fish are caught when they are on the way upstream to lay eggs. Consequently, not enough fish are left to reproduce in large numbers. The members of the cooperative say that they have already reduced their annual catch by 60 percent. However, my study indicates that they took fewer fish because there were fewer fish to catch, not because they were trying to preserve the fish.
Now get ready to answer the questions. You may use your notes to help you answer.
30. What was the speaker assigned to do in the past year?
31. What is one of the problems in Biramichi River?
32. What aspect of the factories along the river does the professor mainly discuss?
33. What does the professor imply about the fact that the annual catch of fish in the Biramichi River has been reduced?
34. What does the professor imply when she says this?
Professor
The members of the cooperative say that they have already reduced their annual catch by 60 percent. However, my study indicates that they took fewer fish because there were fewer fish to catch, not because they were trying to preserve fishes.

选项 A、The reason is that there were fewer fish in the river.
B、Over-fishing in the river has been prohibited.
C、The local Chamber of Commerce tried to preserve the fish.
D、The local fishing cooperative decided to reduce its catch.

答案A

解析 本题属于内在关系题,要求考生能够把握要点之间的内在关系,比如,该题要求考生根据教授所说的一段话(结果),推断出每年捕鱼量减少的原因。文章第四段第二句提到:“Fishare caught when they are on the way upstream to lay eggs.Consequently,not enough fish areleft to reproduce in large numbers(鱼在到上游产卵的途中被捕捞,结果产卵的鱼量减少,因而鱼的繁殖数量也大大降低)”,这与选项A(河中的鱼量减少)吻合,因此为正确选项。选项B(禁止过度捕捞)、C(当地商会竭力保护鱼类)与D(当地捕鱼公司降低了捕鱼量)均与文章不符,是干扰选项。
