Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them. More than that, though, he has also interfered(干预) with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau (凯亚巴布高原) of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.
The Kaibab had a storybook forest of large-sized pine, Douglas fir, white fir, blue and Engelmann spruce. In 1882 a visitor noted, "We, who have wandered through its forests and parks, have come to regard it as the most enchanting(迷人的)region it has ever been our privilege to visit. "This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly.
Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000.
The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd,but a far greater loss resulted from starvation and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.
1. The destruction of the environment of the Kaibab resulted from ________ .
A. turning the forest into cultivated land
B. interfering with natural cycle of forest life
C. forest fires caused by man’s carelessness
D. cutting the trees for building materials
2. "Engelmann spruce"(Para. 2)is most likely the name of ________ .
A. a tree B. an animal
C. a mountain D. a game
3. The number of the deer in the Kaibab had increased enormously in
________ years’ time.
A.25 B.6 C.18 D.12
4.Years later, large numbers of deer in the Kaibab died mainly because of
_______.
A. the cold
B. the organized kill
C. the shortage of food
D. the poor management

The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.
Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.
A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a hose(软管) and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.
When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜函病). The bends can cause a diver to double up in pain. They can even kill him.
60. On the whole, this text is about _________.
A. special mixtures of gases in deep sea. B. the problems a diver faces in deep sea.
C. air pressure under the surface of sea water. D. a kind of illness that man suffers in the sea.
61. The text does not say so, but it makes you think that ____________.
A. deep-sea divers should be in good health.
B. divers explore the deep sea only for treasure.
C. there is a special mixture of gases under the sea.
D. diving under the water too quickly causes a kind of illness.
62. Why does a diver get the bends?
A. The air in his blood is used up. B. His diving suit weighs too much.
C. He comes to the surface too quickly. D. He tries to do exercise under the sea.
63. From the text we can learn that _____________.
