If shyness is making you uncomfortable, it may be time for a few lessons in self-confidence. You can build your confidence by following some suggestions from doctors and psychologists.Make a decision not to hold back in conversations. What you have to say is just as important as what other people say. And don’t turn down party invitations just because of your shyness.Prepare for yourself for being with others in groups. Make a list of the good qualities you have. Then make a list of ideas, experiences, and skills you would like to share with other people . I think about what you would like to say in advance. Then say it.If you start feeling self-conscious in a group, take a deep breath and focus your attention on other people, Remember, you are not alone. Other people are concernedabout the impression they are making, too.No one ever gets over being shy completely, but most people do learn to live with their shyness. Even entertainers admit that they often feel shy. They work at fighting their shy feelings so that they can face the cameras and the public. Just making the effort to control shyness can have many rewards. But perhaps the best reason to fight shyness is to give other people a chance to know about you.56. Where would this article probably appear?A. In a popular magazineB. On the top-line position of a newspaperC. In a science textbookD .In an encyclopedia(百科全书)57. The main purpose of the article is to _____.A. explain how shyness developed.B .recommend ways of dealing with shynessC. persuade readers that shyness is natural.D. prove that shyness can be overcome58. Who probably gives the suggestion for fighting shyness?A. The author of the articleB. Shy men and womenC. Doctors and psychologistsD. Popular entertainersBA new plan for getting children to and from school is being started by a local government in Eastern England. This could end many parents’ worries fearful for their children’s safety on the roads.Until now the local government have only been prepared to provide bus services for children living more than three miles from their school, or sometimes less if special reasons existed. Now it has been decided that if a group of parents ask for help in organizing transport they will be prepared to go ahead, as long as the arrangement will not lose money and children taking part will attend their nearest school.The new plan is to be fired out this term for children living at Milton who attendImpington School. The children live just within the three-mile limit and the local government said in the past that they would not undertake to provide free transport to the school . But now they have agreed to offer a sum of money for a bus service from Milton to Impington and back, a plan which has the support of the school’s headmaster. Between 50 and 60 parents have said they would like their children to take part . Final calculations have still to be carried out, but a government official has said the cost to parents should be less than ￡20 a term. They have been able to arrange the service at a low cost because there is already an agreement with the bus company for a bus to take children who live further away to Impington . The same bus would now just make one more journey to pick up the Milton children. The official said they would get in touch with other groups of parents who in ha d asked if transport could be provided for their children , to see if they would like to take part in the new plan.59. What is the aim of the plan?A.To prevent the students’ road accidentsB. To relieve the traffic pressureC. To save time for the parents and studentsD. To help the parents save money60. Which of the following is possible if the plan is carried out?A. The bus company will make much more moneyB. The children can choose whatever school they likeC. The parents can get rid of their worriesD. The students in Impington School can have free bus rides61. This passage is most probably _____A. a personal letter.B. an advertisementC. a headmaster’s report.D. a newspaper articleCEvery artist knows in his heart that he is saying something to the public. Not only does he want to say it well, but he wants it to be something that has not been said before. He hopes that the public will listen and understand ----he wants toteach them, and he wants them to learn from him.What visional artists like painters want to teach is easy to make out but difficult to explain, because painters translate their experience into shapes and colors, not words. They seem to feel that a certain choice of shapes and colors, out of the countless billions possible, is very interesting for them and worth showing to us. Without their work we should never have notice these particular shapes and colors ,or have felt the delight which they brought to the artists.Most artists take their shapes and colors from the world of nature and from human bodies in movement and at rest; their choices show that these aspects(方面)of the world are worth looking at, that they contain beautiful sights. Modern artists might say that they only choose subjects that provide an interesting pattern, that there is nothing more in it. Yet even they do not choose totally without thinking about the character of their subjects.If one painter chooses to paint a decaying(溃烂的) leg and another a lake in moonlight, each of them is directing our attention to a certain aspect of the world . Each painter is telling us something , showing us something , emphasizing something----- all of which means that, consciously or unconsciously, he is trying to teach us.62. It is hard to explain what a painter is saying because _______.A. most painters do not express themselves wellB. a painter uses unusual words and phrasesC. a painter use shapes and colors instead of wordsD. many painters do not say anything63. Modern artists might say their choice of subjects ______.A. carries a message to the publicB. only provides interesting patternsC. has no pattern or formD. teaches the public important truths64. The writer says that modern art contains______A. nothing but meaningless patterns B .uninteresting aspects of the worldC. subjects chosen partly for their meaningD. completely meaningless subjectsDHow could we possibly think that keeping animals in cages in unnatural environments－mostly for entertainment purposes－is fair and respectful?Zoo officials say they are concerned about animals. However, most zoos remain “collections” of interesting “things” rather than protective habitats(栖息地). Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes.Zoos claim(声称) to educate people and save endangered species(物种), but visitors leave zoos without having learned anything meaningful about the animals’ natural behavior, intelligence, or beauty. Zoos keep animals in small spaces or cages, and most signs only mention the species’ name, diet, and natural range(分布区). The animals’ normal behavior is seldom noticed because zoos don’t usually take care of the animals’ natural needs.The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise. This results in unusually and self-destructive behavior called zoochosis. A worldwide study of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.Furthermore, most animals in zoos are not endangered. Captive breeding(圈养繁殖) of endangered big cats. Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot about their captive breeding programs because they do not want people to worry about a species dying out. In fact, baby animals also attract a lot of paying customers. Haven’t we seen enough competitions to name baby animals?Actually, we will save endangered species only if we save their habitats and put an end to the reasons people kill them. Instead of supporting zoos, we should support groups that work to protect animals’ natural habitats.65．How would the author describe the animals’ life in zoos?A．Dangerous. B．Unhappy. C．Natural. D．Easy.66．In the state of zoochosis, animals _________.A．remain in cages B．behave strangelyC．attack other animals D．enjoy moving around67．What does the author try to argue in the passage?A．Zoos are not worth the public support. B．Zoos fail in their attempt to save animals.C．Zoos should treat animals as human. D.Zoos use animals as a means of making money.EWhen his wife died ,the baby was two. They had six other children, three boys and three girls ,ranging in age from 4 to 16. A few days after he became a widower , the man’s parents and his past wife’s parents came to visit the family. “We’ve been talking” they said ,” about how to take care of all these children and work to make a lining So, we’ve arranged for each child to be placed with a different uncle or aunt .We’re making sure that here in the neighborhood, so you can see them anytime”“ you have no idea how much I appreciate your thoughtfulness.”The man said .”But I want you to know ,”he smiled and continued , “if the children affect my work or if we should need any help ,we’ll let you know.”Over the next few weeks ,the man worked with his children, assigning them small work and giving them responsibilities.

Your partner is someone you have to care for, think about regularly, support and comfort.If you are not fulfilling（履行） these duties, your partner will feel you ignore him or her and hurt. Relationships can feel tense when you are neither confident in yourself nor feel personal self-worth. That pressure you experience on your chest never changes. You feel confused and overwhelmed（受打击）. So, what can you do when you feel yourself slipping into this pattern of emotional outbursts（爆发）, self-doubtand dependency? Take time to consider your own life goals and ambitions（抱负）. Your relationship will improve when you show confidence and be positive. When you feel valuable, it draws people in closer. When you feel down, depressed and low about yourself, it automatically drives people away.So, how can we better understand this relationship? Think of it like this: First,you are happy on your own. You feel comfortable in your own skin and confident aboutyour ambitions and goals.Now, your partner enters into the picture. There is certainlyan adjustment period, where you learn how to expose your inner thoughts and dependon someone other than yourself.If you start from there, you will have a healthy foundation on which to builda mutually-supportive relationship.Ideally, your partner, whom you love and careabout, will ride alongside you on your path to success. In turn, you will supportyour partner to fulfill his or her own life ambitions.You feel confused and overwhelmed when the pressure you第六部分：书面表达（25分）众所周知，这些年我国经济发展迅速，可是环境污染也越来越严重，发展经济与环境保护之间的关系问题一直为社会各界所关注。
