AJohnny Smith was a good math student at a high school. He loved his computer. He came home early every day, then he worked with it till midnight. But Johnny was not a good English student, not good at all. He got an F in his English class. One day after school Johnny joined his computer to the computer in his high school office. The school office computer had the grades of all the students: the math grades, the science grades, the grades in arts and music, and the grades in English. He found his English grade. An F! Johnny changed his English grade from an F to A.Johnny' parents looked at his report card. They were very happy."An A in English!" said Johnny's Dad. "You're a very clever boy, Johnny."Johnny is a hacker. Hackers know how to take information from other computers and put new information in using a modem(调制解调器), they join their computers to other computers secretly. School headmasters and teachers are worried about hackers. So are the police, for some people even take money from bank computer account and put it into their own ones. And they never have to leave home to do it! They are called hackers.21.

They did not have many friends there at first, but they soon met a lot of interesting people, and after a few weeks, they often went to dinner o r to parties at other people’s houses.Then Mrs. Harris said to her husband, “We’ve been to a lot of other people’s houses, and now we must invite them to our house, right?”“Yes, certainly,” answered her husband, “A big party will be the easiest thing, won’t it? Then we can start to invite people to dinner in small numbers next month.”So Mrs. Harris said, “Yes, I’ll invite all our friends here to a big party on 5th December.”“How many people will you invite?” Mr. Harris asked, “Don’t invite too many.”Mr s. Harris was beginning to write the invitations when her husband saw that she was writing, “Party: 6:30 to 8:30 p.m.”“That isn’t very nice, is it?” he said. “You’re telling our guests that they must go at 8:30. Maybe it is impolite.” So Mrs. Harris just wrote “Party: 6:30 p.m.”A lot of guests came, and they all had a good time, so they did not go home at 8:30. In fact they were still there at mid-night when the door bell rang and a policeman arrived. He said, “You must stop making a noise, because someone has complained(抱怨).”Mr. Harris said he did not want to quarrel with the policeman, so everyone went home. They were sorry to have to go.When Mr. and Mrs. Harris were alone again, she said to him. “That was a surprise, wasn’t it? Who complained about the noise?”“I did,” Mr. Harris answered in a tired voice.25. What made Mr. and Mrs. Harris hold a party at their house?A. It was easy to hold a big party at home.B.

Mr. Harris didn’t want his friends to stay late at the partyD. The guests were very tired at the partyCIn the past, many disabled Chinese people led very restricted (受限制的) lives. They had little chance to find work or support themselves. But their situation has improved dramatically over recent decades.In the past five years, the government has been stepping up efforts to help employ disabled people. Huge investments have been made in training, and many disabled people have found jobs and become financially independent.When Wu Zihe was growing up, she was like a prisoner in her home. Having a job was something she could only dream about. But now she is famous fo r her art. Wu is working on a landscape. She said, “I can earn 30 or 40 yuan for paintings like this, if they are sold in groups. If I sell them separately, I can get about 100 yuan. It only takes me one day to finish one painting, so I can earn 1,000 to 2,000 yuan a month.”Wu Zihe practices knife-drawing, which originated in her hometown Dunhua. If one has the eyes, the brain and hands, it takes about a year to learn the basic techniques.Dunhua government’s official Zhang Chunhua said, “We think it suits disabled people very well. So thegovernment spent 10 million yuan to set up this knife-painting training center for them.”Training in the center is free. Even the materials are provided by the government. Since last year, the center has trained over 200 disabled persons like Wu Zihe. They usually earn 500 to 1,000 yuan per month. Sometimes they make as much as 5,000 yuan. That’s much higher than average salaries in the area.This year, the city has set up a center to sell these works. Art fans from more than ten countries and regions have bought paintings.29. How was life for the disabled people in the past?A. With the help of the government, they led a comfortable life.B. According to the law, they led very restricted lives.C. They had to stay at home and had little chance to find jobs.D. They had to learn to paint to earn a living.30. From the passage we can learn that ________.A. the disabled people’s living situation has improved greatly in recent yearsB. all the disabled have found jobs and become financially independent these yearsC. the disabled had to earn a living by workingD. more and more disabled people will learn to paint31. From the last paragraph we can conclude that ____.A. Dunhua has set up a center to sell knife-drawing worksB. people who like knife-drawing art have bought the disabled people’s paintingsC. only the disabled people’s paintings could be sold to foreignersD. perhaps some of Wu Zihe’s paintings could be brought abroad32. What would be the best title of the passage?A. A kind of folk art in China.B. Knife-drawing was first developed in Dunhua.C. A knife-painting training center in Dunhua.D. China helps the disabled find jobs.DPerhaps you have heard a lot about the Internet, but what is it, do you know? The Internet is a network. It uses the telephone to join millions of computers together around the world.Maybe that doesn’t sound very interesting. But when you’ve joined to the Internet, there are lots and lots ofthings you can do. You can do with all kinds of information on the World Wide Web (WWW). You can use QQ to chat with your friends, and they will make responses in a few seconds. You can send E-mails to your friends, and they can get them in a few seconds. You can also go shopping by the Internet without going out.There are many different kinds of computers now. They all can be joined to the Internet. Most of them are small machines sitting on people’s desks at home, but there are still many others in schools, offices or l arge companies. These computers are owned by people and companies, but no one really owns the Internet itself.There are lots of places for you to go into the Internet. For example, your school may have the Internet. You can use it during lessons or free time. Libraries often have computers joined to the Internet. You are welcome to use it at your spare time.Thanks to the Internet, the world is becoming smaller and smaller. It is possible for you to work at home with a computer in front, getting and sending the information you need. It is also possible for you to discuss some projects or assign the work on the Internet instead of at a meeting. In addition, you can buy or sell whatever you want by the Internet. But do you know 98% of the information on the Internet is in English? So what will English be like tomorrow?33. What’s the main idea of the second paragraph?A. Doing with information on the Internet.B. Using the Internet to communicate with friends.C. Things we can do by the Internet.D. Going shopping by the Internet.34. Which may be the most possible place for people to work in the future?A. In the office.B. At home.C. At school.D. In the company.35. What does the writer try to tell us with the last two sentences?A. English is important in using the Internet.B. The Internet is more and more popular.C. Most of the information is in English.D. Every computer must have the Internet.第二节 (共5小题; 每小题2分, 满分10 分)根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项。

I sat Erik in a high chair and 11 everyone quietly sitting or talking. Suddenly, Erik shouted 12 , “Hi.” He patted his fat baby hands on the chair.I looked around and saw a man whose pants were too 13 and his toes 14 out of the shabby shoes. His shirt was dirty and his 15 was rough and unwashed. We were too far from him to smell, but I was sure he smelled. He waved to Erik, “Hi there, baby. I see you.” Everyone in the 16 looked at us and thought the old man was obviously 17 . My husband and I exchanged 18 , “What do we do?” Erik continued to laugh and answer, “Hi.”We finally got through the 19 and headed for the door. As I drew closer to the man, I turned my back 20 to sidestep him and avoid any air he might be 21 . As I did, Erik leaned against my arm, reaching with bot h arms in a baby’s “pick-me-up” 22 . Before I could stop him, Erik had brokenaway from my arms to the man.Suddenly a very old 23 man and a very young baby got together.

About 88,000 international students have found solution. They are attending U.S. community colleges. Such colleges are sometimes called junior colleges. They offer two years of education above the secondary or high school level.Community college students can choose from subjects like medical assistance, computer science or law. At the end of their study program, they receive a document of completion, called a certificate. Some students work toward an associate degree in traditional academic subjects like science or history. After getting it, the students can move on to a four-year college or university. They may have only two years of study left before they receive a bac helor’s degree.Many educational experts agree that saving money is the major reason to consider a community college. The American Association of Community Colleges (AACC) says that a public two-year college costs 3,000 dollar a year on average. That is true if the student lives in the same state as the school. A student at a four-year public college may pay 8,500 dollars a year for classes and user fees. That does not include books and other materials.Some international students may need more preparation in English before entering a community college in the United States. For example, Istrif Montgomery came to the U.S. from Kosovo in 2006. First, he worked to improve his English at Montgomery College for a year. Then for the next two years, he attended classes in basic subjects in a community college.The international students at two-year colleges need to find a place to live. Most community colleges do not provide student housing on their grounds. But Mr Montgomery had a home near by. He was able to ride the bicycle, and he was able to walk if he wanted. In fact, most community college students live within five to ten miles off the college.31. What does the underlined word “it” in Paragraph 2 refer to?A. An associate degree.B. A bachelor’s degree.C. A document of completion.D. A traditional academic subject.32. What’s the biggest advantage of a community college?A. The classes are free of charge.B. The students can save much time.C. The students can save a lot of money.D. It is convenient for students to live in the college.33. Which of the following is TRUE according to the text?A. Mr Montgomery usually goes to school on foot.B. Most students in community colleges don’t l ive far away.C. 8,500 dollars covers all the cost of a four-year public college.D. International students often attend a community college directly.34. What’s the main purpose of the text?A. To encourage students to study abroad.B. To tell the international students how to save money.C. To tell us it’s a good choice to study in public colleges.D. To give some information about community colleges.BWhy do we always want to go faster when talking about travel? We want our cars, trains and planes to get us to places more quickly. This century, there’s been a rise in high-speed rail travel as people have seen the benefits of this form of transport.Spain recently joined the railway revolution with its AVE modern high-speed train that has a top speed of 310 kilometres per hour. Its service from Madrid to Barcelona took 20% of passengers away from Spain’s national airline. In Japan, a magnetic train is being developed that will run at 500 kilometres per hour. Britain has one high-speed line from London to France—HS1, but now it is planning to construct a new line called HS2 which will connect London with the north of England. The UK government’s transport secretary, PatrickMcLoughlin, says it is essential to make sure that the great cities are actually connected and people get the right benefits.The idea of fast train travel may appeal but not if it’s going to be built in your backyard. It’s causing disagreement and people are arguing over the benefits and cost of having shorter journey time and less traffic on the roads. John Kelleher, who is a farmer and lives on the site of the new line says that the government is not taking into consideration the amount that HS2 will destroy on its construction and route through the countryside. Some people are worried the financial and environmental cost will be too high to save just half an hour on a journey.But other countries have shown that high-speed rail is good for the economy. It has helped poorer parts of the country, reduced the need to fly and has mad e train travel cool. For me, there’s nothing better than drinking a cold beer and watching the world go by from the comfort of a train seat. In fact, if it’s that good, what’s the rush? Maybe I will stick with the slow train.35. What can we learn from the second paragraph?A. Patrick McLoughlin is against the construction of HS2.B. The magnetic train in Japan now runs at a speed of 500 k/h.C. The high-speed train in Spain has affected the national airline.D. Britain has built two high-speed lines from London to France.36. What’s mainly talked about in the third paragraph?A. The construction of HS2.B. The popularity of the high-speed rail.C. The development of the high-speed rail.D. The disadvantages of the high-speed rail.37. Which of the following is TRUE according to the text?A. There is no need for people to fly when they travel.B. John Kelleher lives far away from the new line called HS2.C. People in poorer places benefit little from the high-speed rail.D. The author may prefer to choose the slow train while traveling.38. What’s the main topic of the text?A. The railway revolution.B. The means of transport.C. The high-speed rail travel.D. The construction of new lines.CTwo years ago, the modern massive open online course(大规模开放在线课程), or MOOC, came to prominence(出名) when a Stanford computer science professor named Sebastian Thrun made his artificial intelligence course freely available to anyone with an Internet connection — and 150,000 people signed up for it. In addition to traditional course materials such as videos, readings and problem sets, MOOCs provide users with interactive forums(交互式论坛) that help build a community for students, professors and teaching assistants. MOOCs are a recent development in distance education which began to appear in 2012.Now MOOCs are everywhere. Even in faraway developing countries, such as Mongolia, you can find high school students tuning in to courses from American universities, like MIT, Harvard and Berkeley. Coursera, the platform (平台) established by a couple, who are Stanford computer science professors, AndrewNg and Daphne Koller, has more than 400 courses in seven languages from 87 academic partners and some 4.7 million students. EdX, the nonprofit platform established by MIT and Harvard, has 68 courses from 28 academic partners and 1.25 million students. These are just two of the platforms out there.MOOCs began with offering courses in natural science, like math, physics, chemistry and so on. EdX was best known for its introductory computer science courses from Harvard and MIT —but classes now cover everything from finance and law to poetry and music. Through Coursera, you can take “The History of Rock” (University of Rochester) and “How Green Is That Product?”(Northwestern Univ ersity); popular courses on EdX include “Globalization’s Winners and Losers” (Georgetown University) and “Introduction to Philosophy” (MIT).A Mongolian high school student says he is taking a Berkeley class and an MIT course in engineering at the same time. And he plans to apply to Berkeley and MIT this fall. Whether MOOCs will help when it comes to college applications is likely to depend largely on which MOOC a student has completed. (It’s worth noting that many students don’t do the assignments, and onl y 8 percent to 10 percent of those who sign up actually make it to the last MOOC class.) But Stuart Schmill, the admissions officer at MIT, says that for the first time this year the school’s application form includes space for students to list the MOOCs that they’ve taken.39. How is the second paragraph mainly developed?A. By listing numbers.B. By explaining causes.C. By making comparisons.D. By following the time order.40. The author lists some courses in Paragraph 3 to show .A. MOOCs enjoy great popularityB. MOOCs focus on natural scienceC. MOOCs cover a wide range of subjectsD. MOOCs are established by famous universities41. What Stuart Schmill says in the last paragraph implies that .A. applying to college will become easierB. MOOCs will play a part in college applicationsC. MOOCs will replace traditional courses in the futureD. students must take some MOOCs before their applications42. What do we know about MOOCs?A. There are two platforms at present.B. No high school students take MOOCs.C. Not many people can finish the MOOCs that they have taken.D. Most of the MOOCs are taken by American students now.DA phobia (恐怖症) is a strong fear of something that, in reality, presents little or no danger. Most phobias develop in childhood, but they can also develop in adults. The word phobia comes from the Greek language. It means “to fear”.Some phobias are common. The fear of spiders is arachnophobia. The fear of small spaces is called claustrophobia. And the fear of heights is acrophobia.But there are also uncommon phobias. Somniphobia is the fear of falling asleep. And papaphobia is a fear of the leader of the Roman Catholic Church, the Pope. The list of phobias goes on and on.Having a phobia is not a laughing matter. Phobias often create problems in a person’s life. One common phobia that can create problems and hold people back especially at school and at work is the fear of public speaking or glossophobia. “Glossa” is Greek for “tongue”. A student with gloss ophobia may be afraid to speak up in class. At work, a person with this phobia may not speak up in meetings.Whether it is a phobia or a real danger, our bodies react to fear. And we often use physical expressions to describe ourselves when we are afraid. I was so scared that “my blood ran cold” or “I broke out into a cold sweat”.If a book or movie is scary, we often call it “spine-tingling” or “hair-raising”. If something scares us, we can say it “made our hair stand on end” or that it had us “shaking in our shoes”. All these expressions describe what happens to a person’s body when they are afraid.The U.S. president Franklin Delano Roosevelt famously said in his inaugural speech (就职演说) that “the only thing we have to fear is fear itself”. That is a nice idea. But try telling that to a person who is “afraid of their own shadow”.43. Which of the following can most properly describe “phobia”?A. There are no waves without wind.B. Fear is often greater than the danger.C. Fear is everywhere around the world.D. There’s danger where you think it exists.44. The author thinks that having a phobia is something .A. not really scaryB. not so serious at allC. we must take seriouslyD. that is often laughed at45. When you see something horrible you’ll “shake in your shoes”; it is .A. a physical expressionB. a natural reactionC. a sign of a big dangerD. a mental expression46. Roosevelt’s words tend to indicate that .A. only your shadow is fearfulB. there are very few scary thingsC. there is no danger existing at allD. the fear maker is usually yourselfEWhat were you doing before you started reading this? Were you fully focused on another article? Or were you staring out of the window, feeling restless and bored?It is likely to have been the latter. Brief moments of boredom are universal, and are frequently what drive us to stop what we are doing and move to something that we hope will be more exciting.Although boredom is common, it is neither worthless nor favorable, according to Dr. John Eastwood, a psychologist from York University, Toronto. Eastwood is the author of The Unengaged Mind, a new book on the theory of boredom. Boredom, he points out in the book, has been linked with overeating, depression, anxiety and an increased risk of making mistakes. Mistakes at work might not be a matter of life and death formost of us, but if you are an air traffic controller, pilot or nuclear power plant operator, they most certainly can be.Former pilot Sami Franks talks about his experience when he worked for an international airliner. “When you fly a lengthy distance, there are two pilots, one of whom is monitoring all the screens while the other does the paperwork, talks to air traffic control and so on. You need to be alert (警觉) for landing and takeoff, and once you’re 500 ft above the ground, the plane is on autopilot (自动驾驶仪) and it can be very quiet and boring. Some pilots may take a nap (打盹) during this period. Unfortunately, many of them admit seeing the other pilot asleep too when they wake up after the short sleep,” says Franks.However, Dr. Esther, a senior lecturer in education at the University of East Anglia, has studied boredom and says it can be seen in a positive light. “We can’t prevent boredom —it’s an ineluctable human emotion. We have to accept it and find ways to control it. We all need downtime. There’s no need to be fully occupied with (忙于) work at all times,” she says.Children who complain that they have nothing to do on rainy holidays may try to find other things to focus on. Artist Grayson Perry has reportedly spoken of how long periods of boredom in childhood may have developed his creativity.“We all need spare time to think things over,” says Dr. Esther.47. What Sami Franks says suggests that .A. pilots should take turns to sleep when they are workingB. pilots must work together when flyingC. boredom can make pilots distract attentionD. flying a plane is actually not quite fun48. The underlined word “ineluctable” in Paragraph 5 is closest in meaning to “”.A. interestingB. powerfulC. unnecessaryD. unavoidable49. What might be Grayson Perry’s opinion on boredom?A. It often leads to failure.B. It also has a beneficial effect.C. It is more likely to happen to children.D. It makes children lose interest in learning.50. What is the best title for the text?A. Why am I so bored?B. Is boredom bad for you?C. Can I have your attention?D. How can I get rid of boredom?第三部分书面表达(共两节，满分50分)第一节完成句子（共10小题；每小题2分，满分20分）阅读下列各小题，根据汉语提示，用句末括号内的英语单词完成句子。

There are many interesting things to see and to do. You can go to different kinds of museums, plays and films. You can also go shopping to buy things from all over the world.But there are serious problems in big cities too. The cost of living is high, and there are too many people in some of the cities. Every year many people move to the cities because there are some chances to find jobs, to study at good schools, and to receive good medical care. But sometimes these people cannot find work or good places to live in. Also, too many people live in a small space, which makes it hard to keep the cities safe and clean.Some people enjoy living in big cities. Others do not. Before people move to big cities, they should think about the problems of living there.1. Which is the best title for this passage?A. Big Cities.B. New York, London, and Paris.C.

He found an inn(客栈) and wanted to stay there for the night. After he had gone to his room, the owner said to his wife, “Look at his bag, dear. I’m sure there are lots of valuable things in it. I want to steal it when he is asleep.”“No, no,”said the woman. “He must look for his bag tomorrow morning. Then he’ll take you before the judge.”They thought and at last the woman had an idea. “We have forgetful grass,”said the woman, “Why not put some into his food? If he has the food, he will forget to take his bag away.”“How clever you are!”said the owner, “Don’t forget it when you prepare supper for him.”The old man had the food with the forgetful grass and went to bed. The next morning, when the owner got up, he found the door was open and the old man had left with his bag. He woke his wife up and said angrily, “What a fool! Your forgetful grass isn’t useful at all.”“No, no,”said the woman. “I don’t think so. He must forget something.”“Oh, I’ve remembered!”The owner cried out suddenly, “He forgot…”4. The owner and his wife wanted to _______.A. get the man’s bagB. steal the man’s moneyC. make the man pay them moreD. hide the man’s bag5.

Not only the students in China have this problem, but children in the United States also have heavy school bags.Doctors are starting to worry that younger and younger students are having back and neck problems as a result of school bags being too heavy for them.“It’s hard for me to go upstairs with my bag because it’s so heavy,”said Rick Hammond, an 11-year-old student in the US.Rick is among students who have common school bags with two straps(带子) to carry them, but many other students choose rolling(有滚轮的) bags.But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight(重量).Scott Batch, a back doctor, said children under Grade 4 should stay with 10%. But it is also important that older children don’t stay with over 15%, because their bodies are still growing.“Children are losing their balance(平衡) and falling down with their school bags,”he said.Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.One of the best answers is, as some children said, to have no homework at all!8. From the passage we can know that _______.A. only children in China carry too heavy school bagsB. children in other countries don’t carry too heavy bagsC. both children in China and the US carry too heavy school bagsD. only children in the US carry too heavy school bags9. Children feel it hard for them to go upstairs because _______.A. they are too youngB. their school bags are too heavyC. they don’t know how to go upstairsD. their parents don’t always go upstairs with them together10. According to the doctor, Scott Batch, if a child in Grade 5 weighs(重) about30 kilos, the school bag he carries should not be over _______.A. 5 kilosB. 3 kilosC. 5.5 kilosD. 4.5 kilos11. Some students think the best answer to this problem is that _______.A. they should have a little homework to do after they get homeB. their teachers had better not ask them to do any homeworkC. they should only take home library books they will read that nightD. they should use thin workbooks instead of thick onesDHealthy Habits, Healthy BodyFeel tired lately? Has a doctor said he can’t find anything wrong with you? Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you.Then, consider this: you might be in a state of subhealth(亚健康).Subhealth, also called the third state or gray state, is explained as a borderline state between health and disease.According to the investigation(调查) by the National Health Organization,over 45 percent of subhealthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-weeks.Symptoms(征兆)include a lack of energy, depression(压抑), slow reactions, insomnia (失眠), agitation, and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.The key to preventing and recovering from subhealth, according to some medical experts, is to form good living habits, alternate (轮流的)work and rest, exercise regularly, and take part in open air activities.As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements —vitamins and trace elements that are important to the body.Nutrition(营养) experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract(消化系统). They also say that a balanced diet is very helpful in avoiding subhealth.12. It may be easy for middle-aged people to be in a state of subhealth because _______.A. they have used up their energyB. they have lost their living hopesC. they have more pressure in life and workD. they begin to get older13.
