These gray cards are of all possible shades of gray land includ

8、e white and black. on each card a watch-glass is placed .The watch-glass on the blue card has some syrup (果汁 ) in it; all the others are empty. After a short time bees find the syrup, and they come for it again and again. Then, after some hours, we take away the watch-glass of syrup which was on the

9、 bluecard and put an empty one in its place. Now what do the bees do? They still go straight to the blue card, although there is no syrup there. They do not go to any of the gray cards, in spite of the fact that one of the gray cards is of exactly the same brightness as the blue card. Thus the bees

10、do not mistake any shade of gray. for blue. In his way we have proved that they do really see blue as a color. We can find out in just the same way what other colors bees can see. It turns out that bees can see various colors, but these insects differ from us as regards their color-sense in two very

11、 interesting ways. Suppose we train bees to come to a red card, and, having done so, we put the red card on the table in the garden among the set of different gray cards. This time we find that the bees mistake red for dark gray or black. They cannot distinguish between them. This means that red is

12、not a color at all for bees; for them it is just dark gray or black. That is one strange fact; here is another. A rainbow is red on one edge, violet on the other. Outside the violet of the rainbow there is another color which we cannot see at all. This color beyond the violet, invisible to us, is ca

13、lled the ultra-violet. Although it is invisible, we know that the ultra -violet is there because it affects a photographic plate. Now, although we are unable to see ultra -violet light, bees can do so; for them ultra -violet is a colon Thus bees see a color which we cannot even imagine. This has bee

14、n found out by training bees to come for syrup to various parts of a spectrum, or artificial rainbow, thrown by a prism on a table in a dark room. In such an experiment the insects can be taught to fly to the ultra-violet, which for us is just darkness. 16 Experiment with bees described in the first

15、 and second paragraphs tell us that bees regard blue as a colon （ A） True （ B） False （ C） Not mentioned 17 The third paragraph tells us that bees also regard red as a color. （ A） True （ B） False （ C） Not mentioned 18 The experiment described in the second paragraph aimed to find out that bees are no

16、t able to see gray as a color. （ A） True （ B） False （ C） Not mentioned 19 An artificial rainbow was created for the experiment to see whether bees can recognize the ultra-violet as a colon （ A） Tree （ B） False （ C） Not mentioned 20 The fourth paragraph tells us that bees may be harmed by ultra-viole

17、t light. （ A） Tree （ B） False （ C） Not mentioned 21 We can conclude from the passage that bees recognize colors in the same way as human beings. （ A） True （ B） False P （ C） Not mentioned 22 Bees are more sensitive to colors than human beings. （ A） True （ B） False （ C） Not mentioned 三、 概括大意与完成句子 (第 2

The energy that comes from a source of light is not limited to the kind of energy you can see. Heat is giv

19、en off by a flame or an electric light. On a cloudy day it is possible to get a sunburn even though you feel cool. Visible light and the kind of energy that produce warmth and sunburn are examples of electromagnetic energy. The sun is 93 million miles from the earth. Yet we can use energy from the s

20、un because electromagnetic energy travels through space. Many other kinds of energy are also types of electromagnetic energy. Radio, television, and radar signals travel from transmitters to receivers as low-energy electromagnetic waves. Infrared (红外线的 ) radiation is an electromagnetic wave. When it

21、 is absorbed by matter, heat is produced. Waves of infrared and visible light have more energy than waves of radio, television, or radar. Ultraviolet rays (紫外线 ) and X-rays are electromagnetic waves with even greater amounts of energy. Infrared radiation is used in cooking food and heating buildings

22、. Sunlight and electric lights are part of our requirements for normal living. Ultraviolet radiation is useful in killing certain disease organisms. X-rays and gamma rays have so mush energy that they travel right through solid objects. They can be used to detect and treat cancer. X-rays are used in

23、 industry to find hidden cracks in metal, and in medicine to reveal broken bones. Usually we use electricity to generate electromagnetic energy. The source of most of our energy is the sun. Heat from the sun causes water to evaporate. When the water falls to the earth as rain, some of it is trapped

24、behind dams and then used to operate electric generators. Other generators are powered by coal, but the energy stored in coal came from the sun, too. Until recently, the source of the tremendous amount of energy given off by the sun was a puzzle. If the sun depended on chemical reactions, it would h

25、ave used up all its energy long ago. Experiments with electromagnetic radiation led to the theory that mass can be converted into energy. About forty years after the theory was proposed, nuclear energy was harnessed (利用 ) by man. Chemical energy comes from electron (电子 ) rearrangement. Nuclear energ

26、y comes from a Change in the nucleus of an atom. Compared with chemical reactions, nuclear reactions release millions of times more energy per pound of fuel. We now believe that the suns energy comes from the nuclear reactions in which hydrogen is changed into helium (氦 ). Nuclear energy is beginnin

27、g to compete with coal as an economical source of power to generate electricity. It is also being used to operate engines in large ships. Scientists continue to seek new and better methods of obtaining and using energy. 23 A. Nuclear reactions as the lasting source of the suns energy. B. The most im

28、portant source of energy. C. Types of electromagnetic energy. D. The machines used for energy generation. E. Seeking new sources of energy. F. The use of ultraviolet radiation in medicine. 23 Paragraph 3 _. 24 Paragraph 4 _. 25 Paragraph 5 _. 26 Paragraph 6 _. 27 A. when it is absorbed by matter B.

29、when it is cloudy C. because they can pass through solid objects D. when the sunrays are fierce E. when a change in the nucleus of an atom takes place F. when electron rearrangement takes place 27 One can get a sunburn even _. 28 Infrared radiation can produce heat _. 29 X-rays and gamma rays can be

30、 used to detect and treat cancer _. 30 Chemical energy is generated _. 四、 阅读理解 (第 31-45题，每题 3分，共 45分 ) 下面有 3篇短文后有 5道题。请根据短文内容，为每题选 1个最佳选项。 31 U.S. Blacks Hard-hit by Cancer Death rates for cancer are falling for all Americans, but black Americans are still more likely to die of cancer than whites, t

31、he American Cancer Society said Monday. In a special report on cancer and blacks, the organization said blacks are usually diagnosed with cancer later than whites, and they are more likely to die of the disease. This could be because of unequal (不平等的 ) access to medical care, because blacks are more

32、 likely to have other diseases as well, and perhaps because of differences in the biology (生物学 ) of the cancer itself, the report added. “In general, black Americans have less hope of surviving five years after diagnosis than whites for all cancer sites and all .stages of diagnosis,“ the report said

33、. “In describing cancer statistics for black Americans, this report recognizes that many of the differences associated with race may be caused by unfair social and economic differences and unequal access to medical care.“ The cancer society said blacks should be encouraged to get check-ups (体格检查 ) e

34、arlier, when cancer is more treatable, and it said more research is needed to see if biological differences play a role. “The new statistics emphasize the continuing importance of wiping out these unfair social differences through public policy and education efforts,“ the organization said in a stat

35、ement. But it also noted a drop in cancer death rates. “Cancer death rates in both sexes for all sites combined have dropped greatly among black Americans since 1992, as have incidence rates (发生率 ),“ said the report. 31 Black Americans are more likely to die of cancer than （ A） people in other count

Since the 1940s, the nations vast industrial base has been fed with a constant stream of new ideas and experti

49、se from science. And though German prosperity (繁荣 ) has faltered (衰退 ) over the past decade because of the huge cost of unifying east and west as well as the global economic decline, it still has an enviable (令人羡慕的 ) record for turning ideas into profit. Much of the reason for that success is the Fraunhofer Society, a network of research institutes that exists solely to solve industrial problems and create sought-after technologies. But today the Fraunhofer institutes ha
