But how can we find out whether animals can see color whe

15、n they cant tell 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, and

16、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 al

17、l experiments that have been done prove that the dog cant tell one color from another. Many times when we think the dog is responding to a color, he is really responding to some other clue or signsmell, size, shape. Dog lovers should not be too disappointed by this because the dogs sense of smell is

18、 so great that it probably compensates for the inability to see in color. The reason for color-blindness in some animals is connected with the fact that most of them hunt by night and dont depend on color, and also that they themselves are usually dull in color, so it isnt important in their lives.

Have you e

23、ver dreamed something that came 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. Heres an example: A woman was ironing clothes.

24、Suddenly she screamed “My father is dead! I saw him sitting in the chair!” Just then, a telegram came. The womans 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 whats behind these str

25、ange mental messages. Heres another exampleone of hundreds of dreams that have come true: A man dreamed he was walking along a road when a horse and carriage came by. The driver said, “Theres room for one more.” The man felt the driver was Death, so he ran away. The next day, the man was getting on

26、a crowded bus. The bus driver said, “Theres room for one more.” Then the man saw that the drivers face was the same face he had seen in the dream. He wouldnt get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed! Some people say stories like these are lies or “c

27、oincidences”. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind. 题目 36 of 501.0 得分The best title for this passage is _.

31、ust treatment by society. Clearly it is unfair, they say, for women to be paid less 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 famil

32、y and to make the important family decisions, and therefore it is right for men to 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 encourage

33、d by equal pay to take full-time jobs, they will be unable to do the things they are 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

34、 escape from the limited place which society expects them to fill, and to have freedom 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

35、 statement about human rights made in the American Declaration of Independence in 1776:”all men are created equal.” They point 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 _

40、 are equalB.the position of women has improved a little in modern timesC.men and women had equal power in early American societyD.governments always consider mens tight more important than womens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

41、 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 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

42、one experiment, flowers were kept in constant darkness. We might expect that the flowers, without any information about the 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

43、sense of time does not depend on information from the outside would; it is, so to speak, inside them, a kind of “inner clock”. 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 wor

44、king of their bodies and influences their activities. Human beings, then, are also influenced by this mysterious power. Whether 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,
