Foreigners in 202 countries and regions worldwide can buy the tickets through their own Olympic committees, ” said Liu.The number of the tickets is yet to be determined, for some stadiums are still under construction and their seating capacity remains unknown. The ticket prices will undergo scientific survey and calculation, according to Liu.“We have conducted a poll (民意检测) on our official website to collect public opinions and constructive suggestions, to make sure that common people can afford the tickets, ” he said.But one thing is certain that the prices of the tickets for the opening ceremony and some popular events will be relatively high, said Liu.

Shuttleworth, who is a South American Internet millionaire, will set off for a dream trip to the International Space Station.“The training has been excellent,”Shuttleworth said from the Star city training center just outside Moscow, Russia. Taking a Russian Soyuz rocket, Shuttleworth will become the world’s second “Space tourist”. Last April, wealthy Californian businessman Dennis Tito paid Russia US $20 million for an eight-day trip to ISS. Tito, 60, helped science by taking some medical tests. Shuttleworth hates being called a tourist. He said he will take responsibility for radio and life support systems in the capsule (太空舱). By the time he leaves for ISS, Shuttleworth will have had about eight months of full-time training.“The training includes weightlessness and centrifuge (离心分离机) training, as well as learninghow to use communications and control systems,”he said. Shuttleworth will carry out three experiments in space for Africa. And he hopes to educate young people about space. “The task is causing excitement among scientists and school kids. I am very satisfied that it is worthwhile. ”Shuttleworth said.He will be met by astronauts at the Space Station, among whom is American Daniel Bursch. Living in space for more than one month now, Bursch has already missed some of the simple pleasures of Earth. In space he can’t, for example, enjoy taking a breath of fresh air on a winter morning.“My family is probably the number one thing I miss like the kids coming into my room and waking me up, ”Bursch said last month in a space-to-ground interview. Bursch landed at the station last December along with two co-workers. They will be on duty there for five and a half months.“We have a mixture of Russian and US food. It’s excellent, ” Bursch said. “But it surely would be nice to have a pizza and a beer! ”79. What is implied but not stated in the passage?A.Shuttleworth hates being called a tourist.B.Shuttleworth will do three experiments in space for the USA.C.The first space tourist is from the USA.D.Bursch has been in the space for more than one month now.80.

When Shuttleworth arrives at the Space Station, ________.A.he can communicate with his family his family by radio conveniently.B.he can meet many American astronautsC.he will be supplied with pizza and beer constantlyD.he will have the experience of weightlessness82. The underlined word “They” in the sixth paragraph refers to ________.A.two co-workersB.Shuttleworth and two co-workersC.Bursch and two co-workersD.Bursch, Shuttleworth and two co-workersDIn many countries, authority is seldom, if ever, questioned, either because it is highly respected or because it is feared. Sometimes, too, because rank has been important in certain societies for a long time, people have been trained never to question those in authority.In other countries, including America, children are trained to question and search for answers. When a child asks a question, he will often be told to go to the library and find the answer for himself. By the time students reach the age of 14 or 15, they may be developing exciting new ideas in all fields of science and arts. To encourage such creativity, there are many national prizes offered to students every year for their scientific discoveries and artistic accomplishments (成就). This interest in questioning and searching may be considered by some people as bad for young people’s manners, that young people lack respect for authority. This impression may be createdwhen visitors notice young Americans asking questions and arguing with older people. However, this is because many Americans have different attitudes toward authority that may exist in other areas of the world. In a work or business situation, ideas are freely and openly discussed and argued. It is important to remember that it is the person’s ideas that are being questioned, not the individual himself. The two are quite separate. The purpose of the searching, questioning, and arguing is to find the facts in a particular situation, and therefore a solution, so that the work of the business can progress in the most effective manner.83. According to the passage, the interest in questioning and searching ______.A.is bad for young people’s mannersB.results in a lack of respect for authorityC.helps to develop creativity and efficiencyD.does harm to the interpersonal relationship at work84. According to the passage, Americans’interest in questioning and searching shows that they ______.A.are rude in social conversationsB.have a strong desire to know about everythingC.desire a high degree of equality and individualityD.want to learn more facts and discuss ideas85. What can we learn from the passage?A.Authority should be respected and strictly followed.B.American youths should be more respectful to the authority.C.It is improper to question the ideas of your superiors and those of older and more experiencedmen.D.It is worthwhile to let students question the authority and find their own answ ers to questions.86. It can be seen that the author is _______ the American attitude towards authority.A. appreciative ofB. proud ofC. critical ofD. indifferent to (冷漠的)EWhy are so many people afraid of failure? Quite simply because no one tells us how to fail so that failure becomes an experience that will lead to growth. We forget that failure in part of human condition and that, as the family therapist (治疗专家) V irginia Satir observes, “every person has the right to fail.”Most parents work hard at either preventing failure or protecting their children from the knowledge that they have failed. One way is to lower standard. A mother describes her child’s hastily made table as “Perfect!” even though it moves unsteadily on uneven legs. Another way is to shift blame. If John fails, his teacher is unfair or stupid.When one of my daughters was ten, she decided to raise money for charity by holding a carnival (嘉年华会). Proud of her, we hastily allowed her to put posters, all over town. We realized too late that she couldn’t possibly handle all the refreshments, shows, and games promised in the posters. The whole family pitched to prevent an embarrassing failure and the next year she advertised an even more ambitious carnival. Why not? We had kept her from discovering her imitations. The trouble with failure prevention devices is that they leave a child unequipped for life in the real world. The young need to learn that no one can be best at everything. No one can win all the time and that it’s possible to enjoy a game even when you don’t win. A child who’s not invited to a birthday party, who doesn’t make the honor roll of the baseball team, feels terrible, of course. But parents should not offer a quick consolation prize or say, “it doesn’t matter”,because it does. The youngster should be allowed to experience disappointment and then be helped to master it.Failure is never pleasurable. It hurts adults and children alike. But it can make a positive contribution to your life once you learn to use it. Step one is to ask “Why did I fail”? Resist the natural impulse to blame someone else. Ask yourself what you did wrong, how you can improve. If someone else can help, don’t be shy about inquiring.Success, which encourages repetition of old behavior, is not nearly as good a teacher as failure. Y ou can learn from a disastrous party how to give a good one, from an ill-chosen first house what to look for in a second. Even failure that seems definitive can prompt fresh thinking, a change of direction. After twelve years of studying ballet, a friend of mine came to a professional company for a job. She was turned down, “Would further training help”? she asked. The ballet master shook his head. “Y ou will never be an advancer”, he said. “Y ou haven’t the body for it”.In such cases, the way to use failure is to take stock courageously, asking, “What have I left? What else can I do? ”My friend put away her toeshoes and moved into dance thereby, a field where she’s both competent and useful. Failure frees one to take risks because there’s less to lose. Often there is renewal of energy —an awareness of new possibilities.87. The author implies that success _________.A.prepare us for life in the real worldB.provides us with much more freedom than failure doesC.is all that really mattersD.doesn’t encourage new thinking88. According to the passage ________.A.parents need to help their children discover their limitationB.parents need to help their children avoid failureC.parents should be aware of their children’s limitationsD.parents should tell their children about limitations89. Which sentence best expresses the central point of the selection?A.Success can come only after many failures.B.No one can succeed all the time.C.Everyone appreciates a good loser.e every failure as an opportunity for growth and improvement.90. Which of the following would be the best title for this selection?A.Teaching Y our Child to Success.B.Learning from FailureC.How to Be successful.D.Why We Are So Afraid of Failure.五、单词拼写(5’)91.
