That was because a professor 36 me to do so. She said, “Now it is the time for you to travel around the world, 37 your knowledge through actual experiences and have fun!” I 38 her.Since I started to work for a 39 company, however, I have done most of my traveling through the Internet. By using the Internet, I have seen the 40 of many cities on my computer screen. And I have really made business 41 , too. With the help of the Internet, I have also got 42 about food in different countries.Therefore, I was beginning to feel that actual trips were 43 necessary when I happened to read a famous chef's (厨师) comment on the Internet. He said, “It is very difficult to have real Italian food in a foreign country, because we enjoy food and the 44 around us at the same time. So why don't you fly over to Italy and enjoy real Italian 45 ?” Those words reminded me of my 46 advice. As information technology 47 , you might be able to do without making some realtrips. But this also means that you will miss the various 48 you can get from traveling.Today there are people who 49 direct communication with others and spend much of their time on the Internet. It is not surprising to see a group of people 50 not with each other but into their micro phones. It seems as if such people are 51 by an invisible wall. They seem to be losing out on a good chance to 52 and talk with other people. I do not think that they are taking good advantage of information technology. We should use information technology as a tool to make our daily 53 more fruitful. However, we should never let it 54 our time for face to -face communication. Let's make use of information technology more 55 and have great fun in experiencing the actual world.36. A. promised B. allowed C. hurried D. encouraged37.

Now more and more women are taking the front seat. More than twenty million people in the United States ride motorcycles.Since 1998 the number of female bikers has risen sharply. Lady Sport Riders began in 1999 in Washington. The women formed the organization to share their love of motorcycle riding. But later it wanted to be more than just an organization for women to gather and ride motorcycles, so it started to organize events that help national health organizations and women’s shelters. It also permits women to share a strong sisterhood, and gives financial awards to poor students. Like other motorcycle clubs, the members of Lady Sport Riders also help their community.Different from male riders, female riders ride for more than fun. This sport gives women a sense of freedom and control. Female riders have helped change motorcycle culture. More than five years ago manufacturers began making equipment especially for women. Some bikes now have smaller, softer seats and controls that are easier to reach. Modern clothes for riding now look goodand still provide protection. In the past, women rode motorcycles that traveled at a moderate speed. Now theirs are as powerful as the ones men ride. Safety is very important when riding because the risk of injury is high. So the women wear protective clothing and equipment at all times, especially for the head.Lady Sport Riders believes women have earned their place in the sport of motorcycle riding. When speaking of male motorcyclists, the members of the club say, “They Made the Game. We Came to Play!”56. What can we learn from the first paragraph?A. Motorcycle riding used to be considered a male sport.B. The number of female motorcyclists is now larger than that of male riders.C. Female motorcyclists are more skilled at riding than male riders.D. More and more women have an adventurous spirit.57. In the beginning, Lady Sport Riders was organized to .A. allow women to take up motorcyclingB. offer help to national health organizationsC. share their great interest in the sport of motorcyclingD. supply financial help to poor students58. What do men motorcyclists mainly expect to get from motorcycling?A. Strength and power.B. A sense of freedom.C. Money and fame.D. Pleasure from this sport.59. Compared with the past, the present equipment makes riding more ______ for women.A. difficultB. pleasantC. riskyD. expensive60. What is the purpose of the passage?A. To talk about the development of motorcycle riding.B. To talk about the characteristics of the sport of motorcycling.C. To introduce a female motorcycle club to readers.D. To talk about the role women have played in the sport of motorcycling.BDear Anne,I like your column very much. I met a girl four years ago at a gym. She was the one who originally approached me and we became good friends. Then one day, she made me really angry, so angry that I just left and we never saw each other again.Looking back, I really regret ending things that way. It was a cowardly act on my part, but I had a terrible temper at that time and let the smallest thing get to me. Recently, I’ve started thinking about her again and I looked up her e-mail address. I thought about writing to say “Hi” and apologize for what I did but I’m not sure. She could still be angry with m e, or maybe she has forgotten me. I feel very lonely and I want to see her again. What should I do?TomDear Tom,She may still be angry with you, and she may have forgotten the friendship between you, but that doesn’t mean she doesn’t deserve an apology. Tom, how many of us have wished for the day that someone who treated us badly saw the light and finally owned up? But we rarely get that kind of expected result. So sure, e-mail her and say “Hi”.Tell her you have been thinking about her and just want to apologize for getting angry and being a coward by walking out on her. But you should remember if she thinks you’re apologizing just because you are lonely, she might dismiss your sincerity. Therefore, don’t mention that. If she wants to see you again, she’ll make sure that happens.Even if she doesn’t want to be your friend, I can assure you, she’ll appreciate the gesture. And it might make you think twice next time you get angry.Anne61. In the letter, Anne is probably ___________.A. Tom’s friendB. Tom’s teacherC. a woman reporterD. a columnist62. What is troubling Tom?A. He can’t get in touch with his former friend.B. He regrets letting his former friend leave him.C. He doesn’t know whet her to apologize to his former friend.D. He is uncertain whether his former friend can forgive him.63. The underlined phrase “owned up” in the third paragraph probably means “”.A. returned one’s wealthB. admitted one’s mista keC. recovered one’s courageD. controlled one’s feeling64. Anne wants to tell Tom that ________.A. an apology is better late than neverB. he should think twice before he gets angryC. it’s no use crying over spilt milkD. he should answer for his wrong doingsC65.As a volunteer in the child center, __________.A. you should follow the schedule of the center strictlyB. you must keep the child you look after indoorsC. you will earn some money for what you have doneD. you yourself can decide how long to stay there66.What may NOT be needed if you apply to Wilder Research program?A. A college degree and library experience.B. Having knowledge of the Internet.C. Being willing to help others.D. Being able to handle emergencies. 67.From the third advertisement, we can learn that __________.A. only individuals can apply for the jobB. applicants should pay close attention to detailC. applicants are required to do some physical workD. applicants will deliver flyers homes in the neighborhood.DMost Americans belie ve that someone isn’t grown-up until the age of 26 and they should complete their education, have a full-time job, have a family to support and be financially independent. They also believe that becoming a real grown-up is a process which begins at about t he age of 20 and takes about five years, according to the report from the University of Chicago’s National Opinion Research Center.The findings are based on a representative sample of 1,398 people over the age of 18 who were surveyed in person. The survey found that people expect the transitions to grown-up status to be completed at the following ages: age 20.9 self-supporting; age 21.1 no longer living with parents; age 21.2 having a full-time job; age 22.3 education completed; age 24.5 being able to support a family financially; age 25.7 getting married; and age 26.2 having a child.“There is a large degree of agreement across social groups on the relative importance of the seven transitions,” said Tom Smith, director of the survey. The only obvious pa ttern of differences ison views about supporting a family, having children and getting married. Older adults consider these more important than younger adults do. This probably shows in large part a change in values across generations away from traditional family values. The most valued step toward reaching adulthood, the survey found, is completing education, followed by full-time employment, supporting a family, financial independence, living independently, and marriage.68. According to the first paragraph, someone is a grown-up when he _______.A. has found a full-time jobB. has finished his study in universityC. can make money and support himself after completing his educationD. can support a family and be financially independent after graduation69. From the passage, we learn that _________.A. being grown-up is just a matter of ageB. being grown-up is a process which takes some timeC. all people think completing education means being grown-upD. the survey found everyone had a different view about being grown-up70. The best title for the passage should be “________”A. It takes a long time to grown up.B. Are we grown-up yet?C. Getting married means being grown-up.D. Completing education means being grown-up.第四部分写作(共三节满分35分)第一节:短文改错(共10 分,每小题1 分,满分10 分)假如英语课上老师要求同学们交换修改作文,请你修改你同桌写的以下作文。

By intelligence we mean a way of living and behaving, especially in a new or anxious situation. If we want to test intelligence, we need to find out how a person acts instead of how much he knows what to do.For example, when in a new situation, an intelligent person thinks about the situation, not about himself or what might happen to him. He tries to find out all he can, and then he acts immediately and tries to do something about it. He probably isn’t sure how it will all work out, but at least he tries. And, if he can’t make things work out right, he doesn’t feel ashamed that he fails; he just tries to learn from his mistakes. An intelligent person, even if he is very young, has a special outlook(人生观) on life , special feeling about life, and knows how he fits into it.If you lo ok at children, you’ll see great difference between what we call “bright” children and “not bright” children. They are actually two different kinds of people, not just the same kind with different amounts of intelligence. For example, the bright child really wants to find out more about life--- he tries to get in touch with everything around him. But the unintelligent child keeps more to himself and his own dream-world; he seems to have a wall between him and life in general.31.According to this passage, intelligence is the ability _________.A. to behave immediatelyB. to deal with lifeC. to do well in schoolD. to know what to do32. In a new situation, an intelligent person _________.A. knows more about what might happen to himB. is sure of the result he will getC. concentrates on the situationD. cares more about himself33.

What’s the main idea of the passage?A. What’s real meaning of intelligence?B. What’s the “bright” children’s behavior?C. What’s a special outlook on life?D. How to live and behave in a new situation?35. In the next part of the passage, the author might continue to talk about __________.A. how to determine what intelligence isB. how education should be changedC. how to judge whether a person is intelligentD. how an unintelligent person should be taught(C)In Mountain View, Calif, nondescript white SUVs winding through the streets might appear ordinary, but a closer look inside shows that humans are not doing the driving -- the car is.A product of Google’s highly secretive research and development unit, Google X lab, Google’s self-driving cars are now being tested on city streets. The cars themselves have to figure out how to share the road with pedestrians, cyclists and other vehicles. On Tuesday, a few journalists -- including CNET's Sumi Das -- were able to take a test-ride.“It’s driving itself. But after about five minutes, everyone is like, ‘Is that all it does?’ It’s just incredibly common once you get used to it," Chip Urmson, the director of Google'sself-driving car project, said.The company has been developing autonomous vehicles since 2009, and aims to make them available by 2017."Previously they had been really restricted to freeway conditions and now they're working in an actual city, which is a much more complex driving situation," Seth Rosenblatt, a senior writer at CNET, explained.Using the latest sensing technology, the vehicle is able to detect every car, person and object in the immediate area. In many ways, the cars handle the streets better than humans by avoiding other cars' blind-spots and shifting slightly in the lane to make room for cyclists, Das reports. However, the software in these vehicles is far from being ready to ship.Still, Google is racing to develop autonomous driving technology, facing competition from established car manufacturers, such as Audi, GM, Ford and Volvo.36. Which of the following is NOT true about the driverless cars?A. The cars were developed by Google in 2009 secretly.B. The cars are equipped with the latest sensor and software.C. The car can avoid obstacles automatically.D. Some journalists took part in the car test.37. What can be inferred according to the passage?A .Google is the only company that produces driverless cars.B. Google is not as famous as Audi, GM and Ford.C. Other car manufacturers are also developing driverless cars.D. The autonomous cars of Google are the best.38. What does the word “ship” in pa ragraph 6 mean?A. sail on seaB. put into marketC. take awayD. board the ship39. What is the purpose of the passage?A. To introduce Google’s new car.B. To tell us the test-ride of Google’s self-driving cars.C. To tell us the comments of journalists.D. To announce Google is producing self-driving cars.40. The passage is taken from _________.A. a science newspaperB. a travel journalC. an entertainment magazineD. a science summaryD)Phil White has just returned from an 18,000 mile, around the world bicycle trip. White had two reasons for making this epic journey. First of all, he wanted to use the trip to raise money for charity, which he did. He raised £70,000 for the British charity, Ox fam. White’s second reason for making the trip was to break the world record and become the faster person to cycle around the world. He is still waiting to find out if he has broken the record or not.White set off from Trafalgar Square, in London, on 19th June 2004 and was back 289 days later. He spent more than 1,300 hours in the saddle (车座) and destroyed four sets of types and three bikes chains. He had the adventure of his life crossing Europe, the Middle East, India, Asia, Australia, New Zealand and the Americas. Amazingly, he did all of this with absolutely no support team. No jeep carrying food, water or medicine. No doctor. Nothing! Just a bike and a very, very long road.The journey was lonely and desperate at times. He also had to fight his way across deserts, through jungles and over mountain. He cycled through heavy rains and temperatures of up to 45 degrees, all to help people in need. There were other dangers along the road. In Iran, he was chased by armed robbers and was lucky to escapee with his life and the little money he had. The worst thing that happened to him was having to cycle into a headwind on a road that crosses the south of Australia. For 1,000 kilometers he battled against the wind that was constantly pushing him.This part of the trip was slow, hard work and depressing, but he made it in the end.Now Mr. White is back and intends to write a book about his adventures.41.
