But how can we find out whether animals can see

14、color when they can us?Scientists have done many experiments to get the answer. The bee has been the subject of hundreds of these tests, because we have been curious to know whether the bee tells flowers apart by their colors. In one of those tests, a bit of syrup was put in front of a blue card, an

15、d no syrup in front of a red card. After a while, the bees would come to the blue card, no matter where it was placed, and even if it had no syrup in front of it. This proved they could tell colors apart.The animal that is probably closest of all to man as a friend, the dog, is color-blind! So far a

16、llexperiments that have been done prove that the dog can t tell one color from another. Many timeswhen we think the dog is responding to a color, he is really responding to some other clue or sign smell, size, shape. Dog lovers should not be too disappointed by this because the dogsense of smell is

17、so great that it probably compensates for the inability to see in color.1.0得分The reason for color-blindness in some animals is connected with the fact that most of them hunt by night and don t depend on color, and also that they themselves are usually dull in color, so it isn important in their live

21、are color-blind is thatA.their eyesight is very poorB.they sleep during the dayC.they don t depend on lightD.they don t rely on color答案关键：D大项 4 of 6 - Reading Comprehension (2)5.0 得分Have you ever suddenly felt that someone you knew was in trouble and he was? Have you ever dreamed something that came

22、 true later? Maybe you have ESP(超感官知觉).ESP stands for Extrasensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.Here s an example: A woman was ironing clothes. Suddenly she screamedMy father i

23、s dead! I sawhim sitting in the chair!” Just then, a telegram came. The woman s father had died of a heart attack.He had died sitting in a chair.There are thousands of stories like this one on record. Scientists are studying them to find out what s behind these strange mental messages. Here s anothe

24、rlejxamne of hundreds ofdreams that have come true:A man dreamed he was walking along a road when a horse and carriage came by. The driver said,“There s room for one more. The man felt the driver was Death, so he ran away. The next day, theman was getti ng on a crowded bus. The bus driver said,“Ther

29、ings which are only dreamsD.things dreamed of only by sick people答案关键：B大项 5 of 6 - Reading Comprehension (3)5.0 得分“Equal pay for equal work is a phrase used by the American women who complain about what they feel is unjust treatment by society. Clearly it is unfair, they say, for women to be paid le

30、ss than men for the same work.People who hold the opposite view (mainly men) have an answer to this. They say that men have more responsibilities than women: a married man is expected to earn money to support his family and to make the important family decisions, and therefore it is right for men to

31、 be paid more. There are some people who hold even stronger views than this and are against married women working at all. When wives go out to work, they say, the home and children are neglected. If women are encouraged by equal pay to take full-time jobs, they will be unable to do the things they a

32、re best at doing: making a comfortable home and bringing up children. They will have to give up their traditional position in society.This is exactly what they want to give up, the women who disagree say. They want to escape from the limited place which society expects them to fill, and to have free

33、dom to choose between a career or home life, or a mixture of the tow. Women have the right not only to equal pay but also to equal opportunities.These women have expressed their opinion forcefully by using the famous statement about humanrights made in the American Declaration of Independence in 177

34、6: all men are created equal. Theypoint out that the meaning of this sentence was“ all human beings are created equal. ”题目41 of 501.0得分The women use the phrase “equal pay for equal work to make an appeal that.A.men should be paid less than womenB.women s work should not be harder than men sC.women s

39、ocietyD.governments always consider men s tight more important than women答案关键：A大项 6 of 6 - Reading Comprehension (4)5.0 得分We have known for a long time that flowers of different plants open and close at different times of day. This is so familiar that there seems to be no need to ask the reason for

40、it. Yet no one really understands why flowers open and close like this at particular times. The process is not as simple as we might think, as recent experiments have shown. In one experiment, flowers were kept inconstant darkness. We might expect that the flowers, without any information about the

41、time of day, did not open as they normally do. In fact, they continued to open at their usual time. This suggests that they have some mysterious way of knowing the time. Their sense of time does not depend on information from the outside would; it is, so to speak, inside them, a kind of“inner clock

42、.This discovery may not seem to be very important. However, it was later found that not just plants but animals- including man- have this “inner clock which controls the working of their bodies and influences their activities. Human beings, then, are also influenced by this mysterious power.Whether

43、we wish it or not, it affects such things in our life as our need for sleep, our need for food, and our ability to concentrate.In the past, this did not matter very much because people lived in natural conditions. In the modern world, things are different: now there are spacemen, airplane pilots and, in ordinary
