41.No one knows for sure when advertising first started. it is possible that it grows out of the discovery that some people did certain kinds of work better than others did them . That led the conception of specialization, which means that people would specialize.or focus on doing one special job. Let’s take a man we’ll call Mr. Fielder, for example, he did everything connected with farming. He planted seeds, tended the fields and harvest and sold his crops. At the same time, he did many other jobs on the farm. However, he didn’t make the bricks for his house, cut his rrees into boards, make the plows, or ant of the other hundreds of things a farm needs. Instead, he got them from people who specialized in doing each of those of things. Suppose there was another man we shall call Mr. Plowright. Using what he knew about farming and working with iron, Mr. Plowright, invented a plow that made farming easier. Mr. Plowright did not really like farming himself and wanted to specialize in really good plows. Perhaps, he thought, other farmers will trade what they grow for one of my plows. How did Mr. Plowright let people know what he was doing? Why, he advertised, of course. First, he opened a shop and then he put up a sign outside the shop to attract customers. That sign may have no more than a plow carved into a piece of wood and a simple arrow pointed to the shop door. It was probably all the information people needed to find Mr. Plowright and his really good plows. Many historians believe that the first outdoor signs were used about five thousand years ago. Even before most people could read, they understood such signs. Shopkeepers would carve into stone, clay or wood symbols for the products they had for sale. A medium in advertising talk is the way you communicate your message. You might sat the first medium used in advertising was signs with symbols. The second medium was audio, or sound although that term isn’t used exactly the way we used today. Originally just human voice and maybe some simple instruments, such as a bell, were used to get people’s attention. A crier, in a historical sense, isn’t someone who seeped easily. It is someone, probably a man with a voice loud enough to be heard over the other noises of a city. In ancient Egypt, shopkeepers may hire such a person to spread the news about their products. Often these earliest forms of advertising involved a newly arrived ship loaded with goods. Perhaps the crier describes the goods, explained where they came from and praised their quality. His job was, in other words, not too different from a TV or radio commercial in today’s world. what probably led the start of advertising?

46. Below is a selection from a popular science book. If blood is red ,why are verns(静脉)blue? Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison. Which works harder, your heart or your brain? That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But ,in the long run, your brain probably tips it, because even when you ‘re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it . Why do teeth fall out, and why don’t they grow back in grown-ups? Baby (or “milk ”) teeth do not last long ; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they’re gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off. Do old people shrink as they age? Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine(嵴柱) becomes shorter and more curved due to disuse and the effects of gravity(重力) . Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards --their legs. arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved. Why does spinning make you dizzy(眩晕的)？ Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But, when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not! Where do feelings and emotions come from? Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area --from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on the planet If exercise wears you out, how can it be good for you? Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy; it’s more that a lack of exercise leaves your body weak and easily affected by disease. When is the colour of blood in a vein near the surface of the skin? (A) Blue. (B) Light yellow. (C) Red (D) Dark reddish purple.

47.Why do some old people look a little shrunken as they age? (A) Because their spine is in active use. (B) Because they are more easily affected by gravity. (C) Because they keep growing backwards. (D) Because their spine becomes more bent.

48. Which of the following statements about our brain is true? (A) In the long run, our brain probably works harder than our heart. (B) When our brain senses the spinning, we will feel dizzy. (C) The brains of the other mammals are as complex as those of humans. (D) Our feelings and emotions come from the most developed area in our brain.

49. What is the main purpose of the selection? (A) To give advice on how to stay healthy. (B) To provide information about our body. (C) To challenge new findings in medical research. (D) To report the latest discoveries in medical science.

50.The baby monkey is much more developed at brith than the human baby. Almost from the moment it is born,the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large,warm, and soft object in its environment , particularly if that object also gives it milk. After a week or so , however, the baby monkey begins to avoid newcomers and focuses its attentions on “mother”-----the real mother or the mother-substitute(母亲代替物). During the first two weeks of its life warmth is perhaps the most important psychological(心理的)thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice fo two types of mother-substitutes ----one covered with cloth and one make of bare wire. IF the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after brith the baby monkeys picked the warm wire mother-substitutes as their favorites. Thereafter they switched and spent most of their time on the more comfortable cloth mother. Why is cloth preferable to bare wire? Sometime that the Harlows called contact(接触)comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers’ skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire does n’t “rub”as well as does soft cloth. Prolonged(长时间)”contact comfort” with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk. According to the Harlows, the basic quality of a baby’s love for its mother os trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no matter how interesting they might be. It screams in terror and curls up into a furry little ball. If its cloth mother is now introduced into the playroom, the baby rushes to it and holds onto it for dear life. After a few minutes of contact comfort, it obviously begins to feel more secure. It then climbs down from the mother-substitute and begins to explore the toys, but often rushes back for a deep embrace (拥抱) as if to make sure that its mother is still there and that all is well. Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding onto its”mother”. Psychologically, what does the baby monkey desire most during the first two weeks of its life? (A)Warmth (B)Milk (C)contact (D)trust
