But how can we find out whether animals can see color when they can’t 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 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 all experiments that have been done prove that the dog can’t 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 sign—smell, size, shape. Dog lovers should not be too disappointed by this because the dog’s sense of smell is 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 don’t depend on color, and also that they themselves are usually dull in color, so it isn’t important in their lives. 題目 31 of 50 1.0 得分It’s difficult for humans to imagine that ________. A.man cannot see all colorsB.other animals have bad eyesightC.some animals are color-blindD.bees are color-blind答案關鍵: C題目 32 of 50 1.0 得分Scientists have found that bees can see colors by ________.

A.learned to always go to a blue cardB.were only attracted to syrupC.went to both red and blue cardsD.could not see the difference between red and blue答案關鍵: A題目 34 of 50 1.0 得分According to the passage, which of these statements is true? A.Dogs can sometimes respond to colors.B.Dog lovers are sometimes disappointed by their pets.C.A dog’s ability to smell is very good.D.It is inconvenient for dogs to be color-blind.答案關鍵: A題目 35 of 50 1.0 得分One reason that some animals are color-blind is that ________. A.their eyesight is very poorB.they sleep during the dayC.they don’t depend on lightD.they don’t rely on color答案關鍵: D大項 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 true later? Maybe you have ESP(超感官知覺). 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 screamed “My father is dead! I saw him 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 another example—one 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, “There’s room for one more.” The man felt the driver was Death, so he ran away. The next day, the man was getting on a crowded bus. The bus driver said, “There’s room for one more.” Then the man saw that the driver’s face was the same face he had seen in the dream. He wouldn’t 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 “coincidences”. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind. 題目 36 of 50 1.0 得分The best title for this passage is ________. A.The Human MindB.A Big LieC.A Horrible DreamD.A Sixth Sense答案關鍵: D題目 37 of 50 1.0 得分ESP lets people know ________.

A.understand the human mindB.predict deathC.understand the five sensesD.avoid accidents答案關鍵: A題目 39 of 50 1.0 得分The example of the man shows an ability to ________. A.avoid traffic accidentsB.judge the good and evil of a personC.know about events that are happening some distance awayD.sense a danger that will actually happen later on答案關鍵: D題目 40 of 50 1.0 得分In this passage, “coincidences” probably means ________. A.things which do not happenB.things which happen by accident without necessary connectionC.things which are only dreamsD.things dreamed of only by sick people答案關鍵: B大項 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 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 family 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 encouraged 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 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 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.” 題目 41 of 50 1.0 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 rates of pay should not differ from men’sD.men should be kinder to women at work.答案關鍵: C題目 42 of 50 1.0 得分Some people are against married women working at all because they say that __________. A.women are only suited to working at homeB.men cannot take care of childrenC.women will not take good care of their homes and childrenD.all men will lose their traditional role in society答案關鍵: C題目 43 of 50 1.0 得分People who disagree with “equal pay for equal work” believe that __________. A.men have to do more in the home than womenB.men have to work much harder than womenC.men can earn money more easily than womenD.men’s responsibilities are different from women’s答案關鍵: D題目 44 of 50 1.0 得分The women who disagree say that __________. A.women need opportunities to get out of the house more oftenB.women want more freedom in deciding the kind of life they leadC.women are no longer interested in taking care of their homesD.If women are given equal pay, their opportunities will be greater答案關鍵: B題目 45 of 50 1.0 得分The women use the statement “all men are created equal” to show that __________. A.a basic principle of American society is that men and women 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 men’s tight more important than women’s答案關鍵: A大項 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 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 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 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 working 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, in ordinary life, a lot of people who have to work at night. It could be very useful, then, to know more about the “inner clock”. 題目 46 of 50 1.0 得分Why do flowers open and close at different times? A.It depends on the time of day.B.They open and close automatically.C.It depends on the amount of light they have.D.Nobody has really a clear understanding why.答案關鍵: D題目 47 of 50 1.0 得分According to the passage, the “inner clock” __________. A.was an unimportant discoveryB.is only found in animalsC.is now clearly understoodD.has an effect on human life答案關鍵: D題目 48 of 50 1.0 得分Further study of the “inner clock” will be useful because __________. A.for many people today, living conditions are unnaturalB.we do not yet understand plants and animals well enoughC.the number of astronauts and airplanes pilots is rapidly increasingD.we should try to live more naturally than we do now答案關鍵: A題目 49 of 50 1.0 得分According to the passage, a recent experiment showed that __________. A.different flowers open and close at different times of dayB.for their opening and closing, flowers do not need information from the outside wouldC.flowers are influenced by weak light even when they are in a dark roomD.flowers can be used for telling the time答案關鍵: B題目 50 of 50 1.0 得分Which of the following statements about man’s “inner clock” is NOT true? A.It affects our ability to think clearly.B.It influences our eating and sleeping habits.C.It depends on information from the outside world.D.It is an important discovery.答案關鍵: C
