He is considered one of the best actors in Hong Kong. Yes, he is Chow Yun-fat.The example of his long hard struggle for success has been used in a chapter in a Hong Kong middle school textbook. Using his experience, students can learn to make the most of their time and to grab every opportunity to succeed.On hearing about this, Chow said happily, “I really hope that my experiences can make young people understand that one should not be afraid of difficulties and setbacks (挫折), for they are the only way to success.”Indeed, Chow has travelled a long and difficult path to reach his success. In 1955, he was born into a poor family in Hong Kong. When he was 17, he had to leave school. He worked in a number of jobs — as a postman, camera salesman and taxi driver. These experiences paved (铺路) the way for him to play all kinds of roles later in life.Chow broke into the film industry in the late 1970s. He was one of the hardest working actors and starred in a number of popular TV dramas and films including “Shanghai Bund”(《上海滩》) and “A Better Tomorrow”. Since 1985, he has won many awards including Taiwan’s Golden Horse Awards and Hong Kong Film Awards.In 1995, he went to Hollywood. Although he was already over 40, he had to learn English. He even put chopsticks in his mouth to practise pronouncing certain sounds. His film, “Crouching Tiger, Hidden Dragon”, began to gain him more fame and recognition around the world. In 1998, the mayor of Chicago set aside January 12 as “Chow Yun-fat Day”.51. Chow Yun-fat has been written into middle school textbooks mainlybecause .A. he plays best in Hong KongB. he keeps on struggling for successC. his experiences are very specialD. he is well thought of52. Chow felt when he learned that he had been written into middle schooltextbooks.A. surprisedB. shyC. sadD. happy53. What can we infer from the passage?A. Chow Yun-fat is proud of his success.B. Chow Yun-fat loves to make a living by selling cameras rather than byperforming.C. Chow Yun-fat has won more awards than other actors.D. Chow Yun-fat is popular both at home and abroad.54. The underlined sentence (in Paragraph 6) suggests .A. chopsticks are of great help to practise English pronunciationB. Chow Yun-fat is willing to struggle with difficultiesC. Chow Yun-fat has suffered a lot before he went to HollywoodD. it is hard for a person who is over 40 years old to learn English55. The author wrote this passage to .A. introduce Chow’s filmsB. praise Chow for his excellent performanceC. call on people to learn from ChowD. show how popular Chow isBA new generation addiction (嗜好) is quickly spreading all over the world. Weboholism, a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive (难以控制的) habit. They cannot stop, and it affects their lives.Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. This obsessive behavior has affected teenagers and college students. They are likely to log on computers and spend long hours at different websites.They become hooked on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades and success at schools. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.Because of the change in their behavior, they begin to isolate (使隔离) themselves from the society and live with their virtual (虚拟的) friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real-life friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect the whole world.56. The main idea of the passage is about .A. the cause of weboholismB. the advantage of weboholismC. the popularity of weboholismD. the influence of weboholism57. The underlined word “obsessive” in Paragraph 2 probably means “”.A. attractiveB. addictiveC. strangeD. potential58. We can infer from the passage that .A. weboholism has the greatest effect on teenagersB. students can hardly balance real and virtual lifeC. people are addicted to games on the InternetD. virtual life is more vivid and attractive anyway59. Which of the following is NOT true of weboholism?A. It is good to the development of the web.B. The chat room language may change social culture.C. The problem will be getting more and more serious later.D. People addicted to the web often become inactive in real life.60. Th e author’s attitude towards weboholism is that of being .A. optimisticB. positiveC. negativeD. acceptableCFor those who make journeys across the world, the speed of travel today has turned the countries into a series of villages. Distances between them appear no greater to a modern traveler than those which once faced men as they walked from village to village. Jet plane fly people from one end of the earth to the other, allowing them a freedom of movement undreamt of a hundred years ago.Yet some people wonder if the revolution in travel has gone too far. A price has been paid, they say, for the conquest (征服) of time and distance. Travel is something to be enjoyed, not endured. The boat offers leisure and time enough to enjoy the ever-changing sights and sounds of a journey. A journey by train also has a special charm about it. Lakes and forests and wild, open plains sweeping past your carriage window create a grand view in which time and distance mean nothing. On board a plane, however, there is just the blank blue of the sky filling the narrow window of the airplane. The soft lighting, in-flight films and gentle music make up the only world you know, and the hours progress slowly.Then there is the time spent being “processed” at a modern airport. People are conveyed like robots along walkways; baggage is weighed, tickets produced, examined and produced yet again before the passenger move again to another waiting area. Journeys by rail and sea take longer, yes, but the hours devoted to being “processed” at departure and arrival in airports are luckily absent. No wonder, then, that the modern high-speed trains are winning back passengers from the airlines.Man, however, is now a world traveler and cannot turn his back on the airplane. The working lives of too many people depend upon it; whole new industries have been built around its design and operation. The holiday maker, too, with limited time to spend, patiently endures the busy airports and limited space of the flight to gain those extra hours and even days, relaxing in the sun. Speed controls people’s lives; time saved, in work or play, is the important thing — or so we are told. Perhaps those first horsemen, riding free across the wild, open plains, were enjoying a better world than the one we know today. They could travel at will, and the clock was not their master.61. What does the writer try to express in Paragraph1?A. Travel by plane has speeded up the growth of villages.B. The speed of modern travel has made distances relatively short.C. The freedom of movement has helped people realize their dreams.D. Man has been fond of travelling rather than staying in one place.62. How does the writer support the underlined statement in Paragraph 2?A. By giving instructionsB. By following the order of timeC. By analyzing cause and effectD. By giving examples63. According to Paragraph 3, passengers are turning back to modern high-speedtrains because .A. they pay less for the ticketsB. they feel safer during the travelC. they can enjoy higher speed of travelD. they don’t have to waste time being “processed”64. What does the last sentence of the passage mean?A. They could enjoy free and relaxing travel.B. They needed the clock to tell the time.C. They preferred travelling on horseback.D. They could travel with their master.65. What is the main idea of the passage?A. Air travel benefits people and industries.B. Train Travel has some advantages over air travel.C. Great changes have taken place in modern travel.D. The high speed of air travel is gained at a cost.DTens of thousands of theatre tickets will be given away to young people next year as part of a government campaign to inspire a lifelong love for theatre.The plan to offer free seats to people whose ages are between 18 to 26 — funded with £2.5 million of taxpayers’ money — was announced yesterday by Andy Burnham, the Culture Secretary. It received a cautious welcome from some in the arts world, who expressed concern that the tickets may not reach the most underprivileged(贫穷的).The plan comes as West End theatres are enjoying record audiences, thanks largely to musicals teaming up with television talent shows. Attendances reached 13.6 million in 2007, up 10 percent on 2006, itself a record year. Total sales were up 18 percent on 2006 to almost £470 million.One theatre source criticized the Government’s priorities (优先考虑的事) in funding free tickets when pensioners (领养老金的人) were struggling to buy food and fuel, saying: “I don’t know why the Government’s wasting money on this. The Yong Vic, as The Times reported today, offers excellent performances at cheap prices.”There was praise for the Government’s plan from Dominic Cooke of the Royal Court Theatre, who said: “I support any move to get young people into theatre, and especially one that aims to do it all over England, not just in London.”Ninety-five publicly funded theatres could apply for funding under the two-year plan. In return, they will offer free tickets on at least one day each week to 18 to 26-year-olds, first-come, first-served. It is likely to be on Mondays, traditionally a quiet night for the theatre.Mr. Burnham said: “A young person attending the theatre can find it an exciting experience, and be inspired to expl ore a new world. But sometimes people miss out on it because they fear it’s ‘not for them’. It’s time to change this perception.”Jeremy Hunt, the Shadow Culture Secretary, said: “The real issue is not getting enthusiastic children into the theatre, but improving arts education so that more young people want to go in the first place. For too many children theatres are a no-go area”66. Critics of the plan argued that .A. the theatres would be overcrowdedB. it would be a waste of moneyC. pensioners wouldn’t get free ticketsD. the government wouldn’t be able to afford it67. According to the supporters, the plan should .A. benefit the television industryB. focus on producing better playsC. help increase the sales of ticketsD. include all the young people in England68. Which of the following is TRUE about the plan?A. Ninety-five theatres have received funding.B. Everyone will get at least one free ticket.C. It may not benefit all the young people.D. Free tickets are offered once every day.69. We can infer from the passage that in England .A. many plays are not for young peopleB. many young people don’t like theatreC. people know little about the planD. children used to receive good arts education70. According to the passage, the plan to offer free tickets to young people seems______.A. controversialB. inspiringC. excitingD. unreasonable第二节:阅读填空Getting your children to study can be a little like getting them to eat their vegetables.71 . Make a study time and have it at the same time every day. This will help your kids to learn to schedule their day and will give them a sense of control over how they spend their time.Allow them to study in blocks of time, such as for half an hour with a five-minute break in the middle.72 . Ideal study times are after dinner or right after school before dinner.Never allow your children to study in front of the television, as that will encourage passive activity.73 .You’ll also need to help your kids find the right place to study. After you’ve set up a good study time for little learners, set up a good place where they can get those creative juices flowing.74 . Make sure there is a table or a desk and a comfortable chair.75 .This includes helping them out with their homework sometimes and being there for them with the answers to any questions. The input you give your children during study periods will help form a bond and help make studying enjoyable.A. Pick a place where your children can study properly.B. Hold them to the schedule they create for themselves.C. Finally, spend time with your kids when they’re studying.D. Keep the atmosphere light and offer lots of encouragement, too.E. Instead, use TV as a treat or a reward when the homework is completed.F. Try to stop this bad habit by offering some sort of reward.G. One of the best ways to form good study habits for your kids is to design aschedule that they keep to.II卷(共55分)一.单词拼写: 用人教版U3、U4、U5以及New Headway U2中所学的新单词填空。

A price has been paid, they say, for the conquest (征服) of time and distance. Travel is something to be enjoyed, not endured. The boat offers leisure and time enough to enjoy the ever-changing sights and sounds of a journey. A journey by train also has a special charm about it. Lakes and forests and wild, open plains sweeping past your carriage window create a grand view in which time and distance mean nothing. On board a plane, however, there is just the blank blue of the sky filling the narrow window of the airplane. The soft lighting, in-flight films and gentle music make up the only world you know, and the hours progress slowly.Then there is the time spent being “processed” at a modern airport. People are conveyed like robots along walkways; baggage is weighed, tickets produced, examined and produced yet again before the passenger move again to another waiting area. Journeys by rail and sea take longer, yes, but the hours devoted to being “processed” at departure and arrival in airports are luckily absent. No wonder, then, that the modern high-speed trains are winning back passengers from the airlines.Man, however, is now a world traveler and cannot turn his back on the airplane. The working lives of too many people depend upon it; whole new industries have been built around its design and operation. The holiday maker, too, with limited time to spend, patiently endures the busy airports and limited space of the flight to gain those extra hours and even days, relaxing in the sun. Speed controls people’s lives; time saved, in work or play, is the important thing —or so we are told. Perhaps those first horsemen, riding free across the wild, open plains, wereenjoying a better world than the one we know today. They could travel at will, and the clock was not their master.61. What does the writer try to express in Paragraph1?A. Travel by plane has speeded up the growth of villages.B. The speed of modern travel has made distances relatively short.C. The freedom of movement has helped people realize their dreams.D. Man has been fond of travelling rather than staying in one place.62. How does the writer support the underlined statement in Paragraph 2?A. By giving instructionsB. By following the order of timeC. By analyzing cause and effectD. By giving examples63. According to Paragraph 3, passengers are turning back to modern high-speedtrains because .A. they pay less for the ticketsB. they feel safer during the travelC. they can enjoy higher speed of travelD. they don’t have to waste time being “processed”64. What does the last sentence of the passage mean?A. They could enjoy free and relaxing travel.B. They needed the clock to tell the time.C. They preferred travelling on horseback.D. They could travel with their master.65. What is the main idea of the passage?A. Air travel benefits people and industries.B. Train Travel has some advantages over air travel.C. Great changes have taken place in modern travel.D. The high speed of air travel is gained at a cost.DTens of thousands of theatre tickets will be given away to young people next year as part of a government campaign to inspire a lifelong love for theatre.The plan to offer free seats to people whose ages are between 18 to 26 — funded with £2.5 million of taxpayers’ money — was announced yesterday by Andy Burnham, the Culture Secretary. It received a cautious welcome from some in the arts world, who expressed concern that the tickets may not reach the most underprivileged(贫穷的).The plan comes as West End theatres are enjoying record audiences, thanks largely to musicals teaming up with television talent shows. Attendances reached 13.6 million in 2007, up 10 percent on 2006, itself a record year. Total sales were up 18 percent on 2006 to almost £470 million.One theatre source criticized the Government’s priorities (优先考虑的事) in funding free tickets when pensioners (领养老金的人) were struggling to buy food and fuel, saying: “I don’t know why the Government’s wasting money on this. The Yong Vic, as The Times reported today, offers excellent performances at cheap prices.”There was praise for the Government’s plan from Dominic Cooke of the Royal Court Theatre, who said: “I support any move to get young people into theatre, and especially one that aims to do it all over England, not just in London.”Ninety-five publicly funded theatres could apply for funding under the two-year plan. In return,they will offer free tickets on at least one day each week to 18 to 26-year-olds, first-come, first-served. It is likely to be on Mondays, traditionally a quiet night for the theatre.Mr. Burnham said: “A young person attending the theatre can find it an exciting experience, and be inspired to explore a new world. But sometimes people miss out on it because they fear it’s ‘not for them’. It’s time to change this perception.”Jeremy Hunt, the Shadow Culture Secretary, said: “The real issue is not getting enthusiastic children into the theatre, but improving arts education so that more young people want to go in the first place. For too many children theatres are a no-go area”66. Critics of the plan argued that .A. the theatres would be overcrowdedB. it would be a waste of moneyC. pensioners wouldn’t get free ticketsD. the government wouldn’t be able to afford it67. According to the supporters, the plan should .A. benefit the television industryB. focus on producing better playsC. help increase the sales of ticketsD. include all the young people in England68. Which of the following is TRUE about the plan?A. Ninety-five theatres have received funding.B. Everyone will get at least one free ticket.C. It may not benefit all the young people.D. Free tickets are offered once every day.69. We can infer from the passage that in England .A. many plays are not for young peopleB. many young people don’t like theatreC. people know little about the planD. children used to receive good arts education70. According to the passage, the plan to offer free tickets to young people seems______.A. controversialB. inspiringC. excitingD. unreasonable第二节:阅读填空Getting your children to study can be a little like getting them to eat their vegetables.71 . Make a study time and have it at the same time every day. This will help your kids to learn to schedule their day and will give them a sense of control over how they spend their time.Allow them to study in blocks of time, such as for half an hour with a five-minute break in the middle. 72 . Ideal study times are after dinner or right after school before dinner.Never allow your children to study in front of the television, as that will encourage passive activity. 73 .You’ll also need to help your kids find the right place to study. After you’ve set up a good study time for little learners, set up a good place where they can get those creative juices flowing.74 . Make sure there is a table or a desk and a comfortable chair.75 .This includes helping them out with their homework sometimes and being there for them with the answers to any questions. The input you give your children during study periods will help form a bond and help make studying enjoyable.A. Pick a place where your children can study properly.B. Hold them to the schedule they create for themselves.C. Finally, spend time with your kids when they’re studying.D. Keep the atmosphere light and offer lots of encouragement, too.E. Instead, use TV as a treat or a reward when the homework is completed.F. Try to stop this bad habit by offering some sort of reward.G. One of the best ways to form good study habits for your kids is to designaschedule that they keep to.II卷 (共 55分)一.单词拼写: 用人教版U3、U4、U5以及New Headway U2中所学的新单词填空。
