    Bolivia has a population of three and a half million. About　　 one-tenth of the total population are white; one-fourth are mixed　　 Indians and white; and more than half are full-blooded Indians. The　　 government and the industries are under the control of the white　　 people.

　　 　　 　　

    The Indians today live in much the same way as their ancestors (祖　　 先). Most of them are farmers. Many work in the mines, for mining is　　 the most important industry in Bolivia. Of all the mining products,　　 tin is the most important, which makes up three-fourths of all　　 Bolivia's exports (出口). The eastern slopes (坡) of the Andes, since　　 there are very few roads there, are fertile (富饶的) but not highly　　 developed. The two primary means of transportation are river boats and　　 porters. East of the hill region are the great plains where tropical　　 (热带的) plants are grown. A serious problem for Bolivia is the　　 transport of food from the warm regions, where it is grown, to the　　 mountainous regions, where most of the people live.

　　 　　 　　

    Bolivia gained its independence (独立) from Spain about a hundred　　 years ago. It has been slow in developing, but its rich resources　　 promise a better future for it.

Dear Editor:

　　     Once upon a time (not so very long ago, either!) industrial goods　　 were made to last forever. If you bought a car or a stove, it was a　　 once-in-a-life time investment (投资). You paid good money for it, and　　 you took care of it. Today, industry has persuaded us that products　　 shouldn't last a long time. It's cheaper to throw them away than it is　　 to repair them. This has led directly to the "throw-away society" which　　 is a great waste of the earth's resources.

　　

　　    Just think of the cars that are traded in daily, just because they　　 are out of fashion (流行式样). Think of the expensive packaging　　 material that is thrown away every time a new object is bought. And we　　 shoppers have to pay for that material! Our industrial society has　　 turned us into spoiled (宠坏的) children. This wastefulness has got us　　 into the trouble we are in now. When we have no resources left, then　　 we'll start to take care of what we have. But why can't we act before　　 this happens? Why can't we go back to being a society in which the　　 prevention of waste is a virtue?

阅读下列短文, 从所给的四个选项中, 选出最佳答案。

　　

    Fish hear sounds, though they have simply no ears outside their　　 bodies. However, fish do have ears inside their bodies near the brain,　　 and they hear very well with them. Some fish have been taught to　　 recognize the difference between sounds better than some human beings　　 do.

    Many underwater animals make noises only by chance while they are　　 doing something else. Other sounds are real communications of a simple　　 sort, telling one fish of the presence and direction of another. A few　　 noises may be warning messages or discovery of food, etc. The earliest　　 scientific report on fish sounds referred to one of these.

　　

    A new field in science is learning to recognize and use underwater　　 sounds. It relies on the same skill that man has shown in recognizing　　 birds and other land creatures by their calls. But this method is a　　 greater challenge than bird watching, for many of the animals of the　　 sea cannot be followed in any other known way. Their voices cry for　　 attention. Yet we still have too little knowledge about many of the　　 call makers. Perhaps the meaning of the calls and what the call makers　　 are will some day be made known more carefully. It is as though the　　 great oceans were for daring man to invade (涌人) them and to learn　　 the secrets of the place from which his forefathers came so long ago.　　

(1)  After reading the passage, we can conclude that_____.［　　］ 

 A. many fish often make meaningless noises　　 　　

 B. sound cannot pass through some fish bodies　　    

 C. sound waves can easily be felt by fish bodies　　    

 D. some fish can easily understand some land creatures' call 

(2)  Which of the following is true of the noises made by underwater　　 animals?　　　　　　　　　　　　　　　　　　　　　　　　［　　］　　 　　

 A. Some are meaningless.

　　 
 B. None of them is meaningless.　　 　　

 C. They are all actual communications.　　 　　

 D. They cannot be heard by human beings. 

(3) Recognizing underwater animals____________.    ［　　］　　   

  A. is totally different from recognizing land creatures by their calls    

  B. is more difficult than recognizing land creatures by their calls　　   

  C. will change people's knowledge of fish　　 　　

  D. is more or less a battle 

(4)  One of the earliest scientific reports on fish sounds was about 　　 　　___________.　　 　　　　　　　　　　　　　　　　   ［　　］　　    

   A. noises made occasionally by underwater animals 

   B. some sort of communication between fish　　   

   C. the difference between sounds 

   D. what sort of fish the call makers was

 (5)  From the last sentence, we can learn that __________.   ［　　］　　    

 A. the human beings have invaded the oceans for long 

 B. more secrets of the great oceans are to be found out 

 C. only very brave people can make use of the great ocean　　   

 D. people are fighting each other to become the master of the great　　 　　   oceans
