      For 170 years,members of a tiny American native tribe have lived and celebrated their traditions on a
small piece of land off the Louisiana coast called Isle de Jean Charles.They fished and they farmed,making
livings by hard work amid the bays and marshes(沼泽).But now the waters that have supported them
are threatening to overwhelm them.
      "I don't think we're going to have to have any other choice except to leave because we're getting
washed away by every storm that comes by," said Albert Naquin,chief of the BiloxiChitimacha tribe."We
have lost more and more land,and it keeps happening."
      Surrounded by the Gulf of Mexico on one side and the marsh on the other,Isle de Jean Charles sits at
the southern tip of Louisiana's rapidly disappearing wetlands,an area that is 3 to 4 miles long and about a
mile wide.The tribe has been living here since 1840.But about a football field worth of land in the region is
lost every half hour because of erosion(侵蚀),storms and rising sea water-a constant process that is
expected to worsen with climate change.
      Isle de Jean Charles has been flooded five times in the last six years,being transformed from a once
lush(繁茂的) landscape into a barren disaster zone.The floodwaters have spread large amounts of salt
across the tiny island,making it nearly impossible for much to grow any more.
      The road to their village has been flooded so often,and now only one narrow road is usable,
which is often covered by water.The fire station was closed a few years ago,and the island's church was
relocated.Now,only 25 families are left,with a "few dozen" people.A controversial $900 million system of
sea walls to save endangered communities along the Louisiana coast raised hopes here.But the final
design did not include Isle de Jean Charles because officials concluded it simply would cost too much to
protect the relatively few families that were left..
1.What would be the best title of the passage?
A. Climate change threatens an American native tribe.
B. Decreasing population of an American native tribe.
C. The survival of an American native tribe.
D. The harmful effect of climate change
2.We learn from the third paragraph that ________.
A. only a football field worth of land remains for the tribe
B. the southern tip of the wetlands is now in water
C. the tribe is losing its land at a fast speed
D. the tribe has lived here for 300 years
3.What do we know about the remaining land of Isle de Jean Charles?
A. It still remains rich and beautiful.
B. It has become unsuitable for cross to grow.
C. Most of it has become wetlands.
D. All of them has been covered by water.
4.The sea walls will fail to protect the tribe because officials think ________.
A. sea walls will be dangerous for the people living there
B. sea walls will affect the living of the creatures in the sea
C. building sea walls would cost the people living there too much money
D. it's not worthwhile building sea walls to protect the few families

  A special lab at the university of Chicago is busy only at night. It is a dream lab where researchers are at work studying dreamers. Their findings have shown that everyone dreams from three to seven times a night. While the subjects-usually students-are asleep, special machines record their brain waves and eye movements as well as the body movements that tell the end of a dream. Surprisingly, all subjects sleep soundly. Once the dream has started, the dreamer's eyes become more active. As soon as the machine shows that the dream is over, the sleeper is wakened up . He sits up, records his dream, and goes back to sleep-perhaps to dream some more. Researchers have found that if the dreamer is wakened immediately after his dream, he can usually recall the entire dream. If he is allowed to sleep even five more minutes, his memory of the dream will have gone.

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.

Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.

The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities, others lose heart at the first sign of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between “flight or fight” and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Since we can't remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.

44.     People are finding less and less time for relaxing themselves because ________.

       A. they regard working as their greatest enjoyment
       B. they believe that work is superior to relaxation
       C. they are traveling fast all the time
       D. they are becoming busier with their work than ever before

45.     According to the author, the most important character for a good manager is his    

________.

       A. strong will to hold out stress                        

       B. knowing the art of relaxation

       C. high sense of responsibility                           

       D. having control over performance

46.     Which of the following statements is TRUE, according to the passage?

       A. We can find quite a few ways to avoid stress.

       B. Stress is always harmful to people's health

       C. It’s easy to change the habit of keeping oneself busy with work.

       D. Different people can bear different amount of stress.

47.     In the last sentence of the passage, “do so” refers to ________.

       A. “expose ourselves to stress”

       B. “find ways to deal with stress”

       C. “remove stress from our lives”

       D. “establish links between diseases and stress”
