Some answers to these questions and more are as follows:B) Rat: The Chinese see rats as dirty, but they also think laoshu are smart. Most people in the West, however, see little good in the creature. Mice, on the other hand, are more likeable. To be “quiet as a mouse” means to be pleasantly qui et. No one in their right mind wants to be called “a rat”, which suggests that they are crafty, dishonest and selfish.C) Ox: Westerners respect the ox for its strength and hard-working spirit. However, bulls are generally viewed negatively because of their aggressive nature. Cows are considered the “cutest” of the three. In fact, in the US, people often decorate their homes with pictures of cows. The animal is associated with the comfort and quiet of a country home.D) Tiger: Simply put, if you see a tiger, you'd better run. In the West, a tiger may be a beautiful woman or a handsome man. Calling someone a tiger means you understand that they can be dangerous. “Tiger” is also used to describe spoiled little children. They look cute, but they are often up to some bad behavior.E) Rabbit: Many Chinese think the rabbit is cute and docile (温顺的). However, few Americans can say the word “rabbit” without thinking of the clever cartoon character Bugs Bunny. Also, rabbits are known in the West as being extremely reproductive. They can produce three or four litters (一胎生下的小动物) a year, with up to six rabbits in each.F) Dragon: The dragon has come to be a political symbolassociated with China. Many people see China as a great dragon: ancient and beautiful, but also mysterious. The famous song Puff, the Magic Dragon, written by Leonard Lipton and Peter Yarrow, tells the story of one such creature.G) Snake: The snake is often seen as a dangerous or wicked creature, though serpent (蟒蛇) is more often used in contexts discussing evil. The Western image of an evil serpent calls up the Bible's depiction of Satan as a serpent. In the Bible the serpent tempts the first woman Eve into disobeying God.H) Horse: They are known for their beauty and strength. In the US, they may be kept as pets by people who can afford to raise them.I) Sheep: Sheep are viewed docile and weak. They also carry the image of a “follower”. In a church, a priest is a “shepherd (牧羊人)”. The people in the church are his “flock”. The word “sheep” has also been used t o describe people who buy into the latest commercial fashion. The word “goat” is not often used and they have no special meaning.J) Monkey: Throughout the world, monkeys are known to be clever though a little impatient. You might also call someone who li kes to joke around a “monkey”. Nothing is wrong with that. However, in the US, the word has also been used as a racist term that refers to African-Americans.K) Rooster (公鸡): To the Chinese, a rooster is strong and proud. The chicken, on the other hand, is viewed as weak, or even stupid. These views also apply in the West. For instance, you might call someone who is afraid to dive into a pool a “chicken”. The word “hen”, on the other hand, carries a motherly image of protection and comfort.L) Dog: D ogs a re called “man's best friends” in the West.That's why many Westerners refuse to eat them. In the US, an old TV show called Lassie reflects people's high respect for dogs. In every episode, Lassie, a white and brown collie (粗毛牧羊犬), saves the day. However, as loved as dogs are, the word is sometimes used cruelly to refer to an ugly woman.M) Boar: The word “boar” usually refers to a wild pig. These animals are often difficult to capture and extremely ugly. The word “pig” most often refers to the farm-raised animal. They have the reputation of being lazy and dirty. In English, the word can also refer to someone who eats a lot. Also, playboys are sometimes called “pigs” by women who see them as selfish and shallow.46. A tiger can be referred to different things, such as a good-looking person or a spoiled little child.47. In the West, bulls are viewed negatively while cows are considered to be cute.48. In the Westerners' eyes, a mouse is lovely.credit cards.”Dunn says a lot of these young people are never going to getout from under their credit card debt. “Many people are borrowing on credit cards so heavily that payoff rates at these levels are not sufficient to recover their credit card debt by the end of their life, which could have loss implications for the credit card issuing banks.”61.

Animals or children? —A scientist's choice1 I am the enemy! I am one of those cursed, cruel physician scientists involved in animal research. These rumors sting, for I have never thought of myself as an evil person. I became a children's doctor because of my love for children and my supreme desire to keep them healthy. During medical school and residency, I saw many children die of cancer and bloodshed from injury —circumstances against which medicine has made great progress but still has a long way to go. More importantly, I also saw children healthy thanks to advances in medical science such as infant breathing support, powerful new medicines and surgical techniques and the entire field of organ transplantation. My desire to tip the scales in favor of healthy, happy children drew me to medical research.2 My accusers have twisted the truth into a fable and cast me as the devil. They claim that I have no moral compass, that I torture innocent animals for the sole purpose of career advancement, and that my experiments have no relevance tomedicine. Meanwhile, an uncaring public barely watches, convinced that the issue has no significance, and publicity-conscious senators and politicians increasingly give way to the lobbying of animal rights activists.3 We, in medical research, have also been unbelievably uncaring. We have allowed the most extreme animal rights protesters to creep in and frame the issue as one of "animal fraud" and hatred. We have persisted in our belief that a knowledgeable public would consent to the importance of animal research for public health. Perhaps we have been mistaken in not responding to the emotional tone of theargument. Perhaps we should have responded to those sad slogans and posters of animals by waving equally sad posters of children dying of cancer or external wounds. 4 In the animal rights forum, much is made of the volume of pain these animals experience in the name of medical science. Activists deny that we are trying to help and say it is evidence of our evil and cruel nature.A more reasonable argument, however, can be advanced in our defense. Life is often cruel to animals and human beings. Teenagers are flung from trucks and suffer severe head injuries. Young children barely able to walk find themselves at the bottom of swimming pools while a parent is occupied with something else. From everyday germs to gang violence, no life is free of pain. Physicians hoping to relieve the eternal suffering of these tragedies have only three choices: 1) create an animal model of the problem to understand the process and test new therapies; 2) experiment on human beings (some experiments will succeed, most will fail); or 3) leave medical knowledge static, hoping that accidental discoveries will lead us forward.5 Some animal rights activists would suggest an optional fourth choice, claiming that computer models can create animal experiments, thus omitting actualexperiments. Computers can imitate the effects of well-understood principles on complex systems, as in the application of the laws of physics to airplane and automobile design. However, when the principles themselves are in question, as is the case with the complex biological systems of human life under study, computer modeling alone is of little value.6 One of the terrifying effects of arresting the use of animals in medical research is that the impact will not be felt for years or even decades. Drugs to cure infection will remain undiscovered, surgical and diagnostic techniques will remain undeveloped, and fundamental biological processes that might have been understood will remain mysteries. There is the danger that quick decisions by well-meaning politicians will create resolution to diplomatically satisfy the small minority ofloud protesters while the consequences and damaging impact of those decisions will not be apparent until long after.7 Fortunately, most of us enjoy good health, and the agony of watching one's child die has becomea rare experience. Yet our good fortune should not make us unappreciative. Protection from serious sickness and drugs to combat heart disease, high blood pressure and stroke are all based on animal research. Most complex surgical procedures such as heart or hip surgery and organ transplantation surgeries were initially developed in animals. Techniques to replace defective genes, the cause of so much disease, as well as the development of synthetic organs are presently undergoing animal studies. These studies, and any subsequent advances, will effectively end if animal research is severely restricted.8 In America today, death has become an event isolated from our daily existence. As a doctor who has watched many children die and seen their parents' infinite grief, I am particularly angered by any minute expression of caring for the sufferingof creatures and so little for sick and dying human beings. People are too protected from the reality of human life and death and what it means.9 Make no mistake, however. I would never advocate needless cruel treatment of animals. The animal rights movement has made a contribution in making us more aware of animals' needs and the need to search harder for suitable alternatives. But if the more radical members of this movement are successful in threatening further research, their efforts will bring about a tragedy that will cost many lives. Hence the real question is whether an uncaring majority can be aroused to protect its future against a loud, but misdirected, minority.。

Workers at the zoo care for hurt or sick animals.At first this unusual place was not a zoo. It was called the Forked River Animal Care Center. The workers there took care of lost or unwanted cats and dogs.The change began in 1977 when a raccoon (浣熊) needed help. The workers cared for the animal. Finally it was better, but it could not care for itself. So people had to allow the raccoon to live at the center.After that,people began taking all kinds of hurt or homeless animals there. So manyanimals were living at the center that it became more like a zoo. It was time for a new name.Popcorn Park Zoo got its funny name because many of the animals there like to eat popcorn (爆米花). Also workers at the zoo sell the popcorn to help make money to carefor the animals. People buy the popcorn to feed the animals as well.You can see more than 200 kinds of animals in Popcorn Park Zoo now. All the animals at the zoo get lots of care and love.根据短文内容完成信息卡Information CardAt first, Popcorn Park Zoo was named 41Workers at the zoo look after 42The animal which is allowed to live at the zoo in431977 wasThe zoo got its name because 44This passage probably comes from 4541.42.43.44.45.六、用方框中所给单词的适当形式补全短文(有两词多余)(每小题1分,共10分)Wild animals are important to us.

They kill wild animals for50 and even for fun. Some of the 51 animals have already died out. That means we can't see52 any more. Today wild animals are becoming fewer and 53. If this goes on, there will be no animals left on the earth.54, many people have begun to know the importance of protecting wild animals. And many countries have made some laws(法律) to protect them and stop people 55 killing them. Protecting wild animals is everyone's duty.
