  Lake Titicaca, in the Andes mountain chain in South America, is the highest lake in the world. And for hundreds of years the boats called balsas were the highest boats in the world.

  The balsas are made by the Aymara Indians who fish in waters more than two miles (about 12,700 feet) above sea level. The Indians wrap totora reeds into cigar-shaped bundles and lash the bundles together. The air trapped between the reeds makes a newly made balsa almost unsinkable. The fisherman may stand near the narrower, higher end of this craft as he poles it along;he may sit in the small hollow amidships as he paddles. With a favorable wind, a reed mat fastened to upright poles near the bow, or front, acts as a sail.

  Though steamboats now sail these high waters, the balsas still have one great merit. If they are damaged, materials for repairing or replacing them are right at hand.

1.Lake Titicaca is in the____________.

A.Himalayas of Asia   B.Rocky Mountains of North America

C.Alpine chain in Europe D.Andes of South America

2.The lake's height above sea level is__________.

A.cigar-shaped B.pencil-shaped C.plank-shaped D.None of the above

A. light B. strong C.easy to pilot D.hard to manage

6.The craft may be propelled by use of________.

A. a pole B. a paddle C. the wind D. All of the above

7.The story suggests that materials for repairing a steamboat________.

A.are easily obtained   B. have to be brought in from elsewhere

C.are needed more frequently than for reed boats D. are transported by plane

8.A reed boat cannot be repaired when________.

A.a rock cuts into one bundle of reeds   B. the lashing around a bundle breaks

C.the bundles of reeds become water soaked D. the sail is torn

答案:D;B;D;A;A;D;B;C

  The balsas是什么?this craft又是什么?要在文章中寻求答案,而the small hollow amidships终于告诉你它是什么。因为amidships一词的构成说明了一切。

The balance of natureis not an empty phrase. Nature provides a population to occupy a suitable environment and cuts down surplus population to fit the available food supply. One means of reducing surplus population is predators; others are parasitic diseases. Also, population density produces nervous disorders and even drives animals to mass migrations(移民群),like the lemmings of Norway who plunge(冲入)into the sea.

That predatory population increase to control other animals has long been known. Many years ago, the Hudson’s Bay Company records revealed that the fox population went up and down about a year after rabbit population had gone up and down.

Sometimes a situation occurs in which the predatory population is reduced to a level below which nature can readily replace. On Valcour Island in Lake Champlain, a costly campaign resulted in the elimination(消除)of predatory animals only to have birds and small animals increase for four years afterward. Then, lacking predator control, nature resorted to disease to cut down these populations.

Jamaica had an example of nature’s persistence in providing animals for existing habits. Sugar planters, about 75 years ago, imported mongooses(狐猴)to control rats. The mongooses killed off the rats, kids, puppies, and wildlife. Eventually, food became scarce and the mongoose’s population declines.

1. The fact that the number of predators has much to do with that of other animals     .

A. is not recent knowledge                  B.has just been learned

C.hasn’t been proved yet                      D.is not important now

2. When predator control fails, nature brings animal population into balance by       .

A. eliminating the number of predators

B.seeking the help of disease to reduce other animals

C.increasing the number of other animals

D.replacing the number of predators immediately

3. When the mongooses killed off the rats they     .

A. became problems themselves             B.ate the sugar crop

C.attacked humans                       D.had nothing to eat

4. It is implied in this passage that     .

A. sugar planter imported mongooses to control rats

B.man should never kill animals

C.man has complete control over nature

D.to upset the balance of nature can be troublesome

Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.  

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.  

There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.  

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.  

  64. Which of the following is the author most probably in favor of?

  A. Cycling around a lake.

  B. Motor racing in the desert.

  C. Playing basketball in a gym.

  D. Swimming in a sports center.

  65. What do we know about golf from the passage?

  A. It is popular in Portugal and Spain.

  B. It causes water shortages around the world.

  C. It pollutes the earth with chemicals and wastes.

  D. It needs water and electricity to keep its courses green.

  66. The author uses power walking as an example mainly because______.

  A. it is an outdoor sport

  B. it improves our health

  C. it uses fewer resources

  D. it is recommended by experts

  67. The author writes the passage to_______.

  A. show us the function of major sports

  B. encourage us to go in for green sports

  C. discuss the major influence of popular sports

  D. introduce different types of environment-friendly sports
