Question

    Ocean food plays a very important part in our food supply. Not so long ago, the world’s oceans were filled with different types of fish. Now, a large increase in global overfishing has threatened that supply.

According to the United Nations Food and Agriculture Organization, 90 percent of the world’s fisheries (渔场) are either being fully exploited (开发), or are at risk of being closed down.

With fish supplies running out at home, fishermen are traveling further to find their catch. Frequently, fishermen are crossing over into other countries. As fish supplies closer to their homeland’s shores are decreasing fishermen cross borders to find fish.

Overfishing can be found everywhere, from Mexican fishing boats off the US coast of Florida to Russian fishing boats in the western Bering Sea. However, the effect is felt the strongest in the South China Sea.

On the other side of the world, West Africa is now seeing malign effects of overfishing. For coastal African countries, such as Senegal, the fishing industry is a large part of the national economy. The World Bank reports nearly 20 percent of the Senegalese are working in the fishing industry. Rashid Sumaila is the Director of Fisheries Economic Research at the University of British Columbia. He says communities that depend on fish for income and food, like Senegal, are now at risk.

A.Because they want to protect the environment.

B.Because they want to enjoy the overseas scenery.

2.Where can the most serious overfishing be seen according to the text?

3.What does the underlined word “malign” in the last paragraph probably mean?

4.What can be inferred from the last paragraph?

A.Most people in Africa will be out of work.

【解析】

这是一篇说明文。文章介绍全球过度捕鱼带来的威胁。海洋食物在我们的食物供应中起着非常重要的作用。不久以前，世界上的海洋里充满了各种各样的鱼。现在，全球过度捕捞的大幅增加已经威胁到了这种供应。

1.

细节理解题。根据第三段中With fish supplies running out at home, fishermen are traveling further to find their catch.“由于国内的鱼类供应已经告罄，渔民们不得不前往更远的地方寻找他们的猎物。”由此可知，渔民之所以要跨越国界捕鱼，是因为因为他们国家的鱼类供应正在减少。故选C。

2.

细节理解题。根据第四段最后一句However, the effect is felt the strongest in the South China Sea.“然而，这种影响在南中国海最为强烈。”由此可知，在南海可以看到最严重的过度捕捞。故选B。

3.

词义猜测题。根据最后一段中For coastal African countries, such as Senegal, the fishing industry is a large part of the national economy. “对于非洲沿海国家，例如塞内加尔，渔业是国民经济的一大部分。”和He says communities that depend on fish for income and food, like Senegal, are now at risk.“他说，像塞内加尔这样依靠鱼类收入和食物的社区现在面临危险。”由此可知，On the other side of the world, West Africa is now seeing malign effects of overfishing.（在世界的另一边，西非正面临着过度捕捞的恶果。）所以划线词的意思是“有害的”。故选A。

4.

推理判断题。根据最后一段中On the other side of the world, West Africa is now seeing malign effects of overfishing. For coastal African countries, such as Senegal, the fishing industry is a large part of the national economy.“在世界的另一边，西非正面临着过度捕捞的恶果。对于非洲沿海国家，例如塞内加尔，渔业是国民经济的一大部分。” 和He says communities that depend on fish for income and food, like Senegal, are now at risk.“他说，像塞内加尔这样依靠鱼类收入和食物的社区现在面临危险。”由此可知，过度捕捞对非洲人有一些不好的影响。故选D。
