Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the star in their long-di

10、stance flights.One such bird-a warbler（ 鸣禽 ）-had spent its lifetime in a cage and never flown under the natural sky. Yet it showed an inborn ability touse the stars for guidance. The bird' s cage wasplaced under an artificial star-filled sky at migration time. The bird tried to fly in the same d

11、irection as that taken by his outdoor cousins. Any change in the position of the make-believe stars caused a change in the direction of his flight.Scientists think that warbler, when flying in daylight, use the sun for guidance. But the stars are apparently their principal means of navigation. What

The first great invention was that is still very important today - the wheel. This made it easier to carry heavythings and to travel long distance

26、s.For hundreds of years after that there were few inventions that had as much effect as the wheel. Then in the early 1800' s the world started to chang e. wThaserlittle unknown land left in theworld. People didn' t have to explore much anymore. They began to work instead to make lifebetter.I

27、n the second half of the 19 th century many great inventions were made. Among them were the camera, the electric light and the radio. These all became a big part of our life today.The first part of the 20th century saw more great inventions. The helicopter in 1909, sound movies in 1926, the computer

28、 in 1928, and jet planes in 1930. This was also a time when a new material was first made. Nylon came out in 1935.

The whole body is covered with skin. The surface of th

34、e skin is dead (like the hair and nails), but it is made from a living layer just under the surface. The outside dead layers wear off all the time, with new ones replacing them, and the body forms a totally new skin every three weeks.The skin protects the body from the outside world and it passes in

35、 information from the outside. It helps to keep water in the body and to keep the body at the same temperature. Bacteria (germs) cannot get in through the skin unless it is damaged.If the weather is cold, the blood vessels on the skin squeeze ( 挤压 ) down, or contract, so that as little blood as poss

36、ible comes near the surface. This means that less warmth is lost to the outside. This makes the skin look pale, or even“ blue ” . At the same time, the hairs on the skin are pulleupright by tiny muscles.When it is hot, the blood vessels expand, or get wider again, to allow plenty of blood to run nea

37、r the surface of the skin. This helps the body to loose heat, and the skin may look red. At the same time, The sweat glands produce more sweat, which cools the skin down.If the skin has ever been numb, you will realize how important the feeling from the skin is. Nerves in the skin are sensitive to h

38、eat and cold, sharpness, hardness and softness, wetness and dryness and pain. If one is not able to feel these things, which can act as warning, he is likely to be burned, cut or hurt in other ways.The color of the skin depends on special color cells.

Many of the world ' s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increa

44、se in human population continues at the present rate, there may be much greater harm. Some scientists speak of the increase in numbers of people as“ population pollution ”.About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930, the populatio

45、n was two billion. It was three and a half billion by 1980. It doubled by the year 2000. If the population continues to grow at the same rate, there would be 25 billion people in the world a hundred years from now!Man has been using the earth' s resources more and more rapidly over the years. So

46、me of themare almost gone. Now many people believe that man' s greatest problemis how to control the growth of his own population. The materials in the world will not support the human population, in time to come, if the present rate of increase continues. Already there is overcrowding in the ci

47、ties and hunger in some countries. Can man' s rate of increase continue? Many people believethat human survival in the future depends on the answer to this question.1. The world ' s pollution problems would be less serious ifA. fewer people moved from countryside to the cities.B. More people

50、; s resources.B. The control over the waste of the natural materials.C. How to slow down the increase of population.D. How to stop the birth of new babies.87. While flying in space, astronauts have no weight. It is a condition of weightlessness. How does this affect their heart and blood vessels? Wh

51、at happens to their hearts and blood vessels when they go into space?On earth gravity （引力 ） makes blood flow down towards the feet, so the heart must work to pump blood up. In space blood flows up towards the heart. The effect is similar to what happens when you lie with your feet up and your head d

52、own. The flowing blood is felt by receptors in the walls of arteries （动脉 ） in the upper part of the body and in the heart. These receptors send signals to the brain, but the brain reads them incorrectly. To the brain, the signals means the amount of blood in the body has increased, so the brain tell

53、s other parts of the body to react to the increase in the blood. For example, the body produces more urine （ 尿液 ）, resulting in loss of body fluid and salt. At the same time the astronaut has less desire to drink and so does not replace the lost fluid.As a spacecraft begins to fall back to earth atm

54、osphere, the crew begins to feel gravity. Blood again flows towards the feet and collects there. The heart beats faster in an effort to pumpenough blood to the brain. Some crew members may not get enough blood to the brain and the heart beats too fast. They become sick and even lose consciousness as

55、 their spacecraft reenters the earth atmosphere. To prevent this, special clothing is invited for astronauts to prevent blood collecting in their legs. They put it on just before the craft reenters the earth' s atmosalso drink about a liter （ 升 ） of water and eat some salt to replace the fluid t

56、hey have lost while in space.Weightlessness affects the heart and blood vessels in another way. The heart does not work as hard in a weightless environment as it does in an environment of gravity. When the heart works less hard, the heart muscles become weaker. It is replaced by fibrous tissue and f

57、at.1. If one lies with his feet up and his head down on earth, hisA. heart will pump the blood up to the head.B. blood will flow down towards the feet.C. heart will have to work harder. D. blood will flow up towards the heart.2. What can we infer from the second paragraph of the passage?A. The brain

58、 reads the signals incorrectly because it tends to go wrong in outer spaceB. In space an astronaut should drink some water even when he does not feel thirsty.C. In space the amount of water in the body of an astronaut increase.D. The receptors in the walls of arteries often send wrong signals to the

59、 brain.3. When the spacecraft reenters the earth' s atmosphere some astronauts become sick or even loconsciousness becauseA. their brains cannot get enough blood B. their hearts are not strong enoughC. their blood collects in their feetD. they begin to feel the gravity again4. When the spacecraft enter the earth 'atsmosp
