He sent camera crew out one evening to film the sunset for him.The next morning he said to the men, "Have you provided me with that sunset? ""No, Sir," the men answered.The director was angry. "Why not? " he asked."Well, Sir, " one of the men answered, "we are on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.""But I want a sunset!" the director shouted. "Go to the airport, take the next flight to the west coast, and get one. "But then a young secretary had an idea. "Why don't you photograph a sunrise, " she suggested, "and then play it backwards? Then it'll look like a sunset.""That's a very good idea! " the director said. Then he turned to the camera crew and said, "Tomorrow morning I want you to get me a beautiful sunrise over the sea. "The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay(海湾). Then at nine o'clock they took it to the director. "Here it is, Sir, " they said, and give it to him. He was very pleased.They all went into the studio(摄影棚). "All right, " the director explained, "now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the 'sunset' behind them. "The "sunset" began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.The birds in the file were flying backwards, and the waves on the sea were going away from the beach.86.One evening, the director sent his camera crew out____.A. to watch a beautiful sunsetB. to find an actor and an actressC. to film a scene on the seaD. to meet the audience87.Why did the director want to send his crew to the west coast?A.

Yet I did not know the American society until I was injured in a car accident because after the accident I had to see a doctor-and go to court(法庭).After the accident, my roommate called a doctor for me. I was very grateful and determined to repay him one day. But the next day, he asked me to pay him $200 for what he had done. I was astonished. He had good reason to charge me, he said. And if I wanted to collect money from the person who was responsible for my injury, I'd have to have a good lawyer. Now that he had helped me to find a good doctor, it was only fair that I should pay him.But every time I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time. The final examination report consisted of ten lines, and it cost me $215.My lawyer was all smiles the first time we met. But after that he avoided seeing me at all. he knew very well the other party was responsible for the accident, yet he hardly did anything. He simply waited to collect his money. He was so irresponsible that I decided to dismiss(解雇)him. And he made me pay him $770.Now I had to act as my own lawyer. Due to my inexperience, I told the insurance the date I was leaving America. Knowing that, they played for time, … and I left without getting a cent.My experiences taught me two things about America: firstly, in a country like America money is everything. It is more important than friendship honour or professional morality(职业道德). Secondly, foreigners are still being unfairly treated. So when we talk about America, we should see both its good and bad sides.91.The author's roommate offered to help him because_____.A. he felt sorry for the authorB. he thought it was a chance to make some moneyC. he knew the doctor was a very good oneD. he wanted the author to have a good lawyer92.

Going to court is something every common in AmericaB. One must be very careful while driving a carC. There are more bad sides in America than good sidesD. Money is more important than other things in the US(C)Laptop(便携式)computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptop connect people to their work place. In the United States today, laptops also connect students to their classrooms.Westlake College in Virginia will start a laptop computer program that allows students to do school work anywhere they want. Within five years, each of the 1,500 students at the college will receive a laptop. The laptops are a part of a $10million computer program at Westlake, a 110-year old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to "speak" with their tethers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State Officials also are testing laptop programs at other universities, too.At Westlake College, more than 60 percent of the staff use the computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, "Here we are in the middle of Virginia and we're giving students a window on the world. They can see everything and do everything. "96 The main purpose of the laptop program is to give each student a laptop to____.A. use for their schoolworkB. access the InternetC. work at homeD. connect them to libraries97 Why is the word "speak" in the second paragraph in quotation mark?A.

A window on the world in the last paragraph means that students can____.A. attend lectures on information technologyB. travel around the worldC. get information from around the worldD. have free laptops100. What can we infer(推断)passage?A. The program is successfulB. The program is not workableC. The program is too expensiveD. We don't know the result yet(D)Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for yeas. Now researchers say there are three different types of loneliness.The first kind of loneliness is temporary(暂时的). This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situational loneliness, is a natural result of a particular situation-for example, family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.The third kind of loneliness is the most severe. Unlike the second type, chronic(长期的)usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.Psychologists agree that one important factor in loneliness is a person's social contacts, e.g. friends, family members, co-workers, etc. we dependon various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their popularity.Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease. While temporary and situational loneliness can be normal, healthy part of life, chronic loneliness can be a sad, and sometimes dangerous condition.101.How would you treat temporary loneliness according to the passage?A. Talk to friendsB. Just ignore itC. Go to see a doctorD. Ask your teachers for guidance102."It" in the last sentence of the second paragraph refers to _____.A. temporary lonelinessB. situational lonelinessC. a new placeD sleeplessness103.The topic of the 4th paragraph is that____.A. one problem of loneliness is a person's social contactsB. we depend on various person for different reasonsC. lonely people don't have many social problemsD. lonely people don't have many friends104. Why do psychologists want to help chronically lonely people?A. Chronic loneliness can cause family problemsB. Chronic loneliness can cause serious illnessC. Chronic loneliness can not be overcomeD. A, B and C are all correct105 What is the best title for the passage?A. Three Kinds of LonelinessB. Loneliness and DiseasesC. Loneliness and Social ContactsD. Chronic LonelinessI.

However, nearly all require some __(50)__ in one’s career in order to attend school full time. Part-time education, that is, attending school at night or for one weekend a month, tends to drag the__(51)__out over time and puts the completion of a degree program out of reach of many people. __(52)__, such programs require a fixed time commitment which can also impact __(53)__ on one’s career and family time.Of the many __(54)__ to teaching and learning, however, perhaps the most flexible and accommodating is that called distance learning. Distance learning is an educational method, which allows the studentsthe __(55)__ to study at his or her own pace to achieve the __(56)__ goals, which are so necessary in today’s world. The time required to study may be set aside at the student’s convenience with due __(57)__ to all life’s other requirements. Besides, the student may __(58)__ in distance learning courses from virtually any place in the world, while continuing to pursue their chosen career. Tutorial assistance may be __(59)__through regular airmail, telephone, fax machine, teleconferencing and over the Internet.Good distance learning programs are characterized by the inclusion of a subject __(60)__ tool with every subject. This precludes(排除) the requirement for a student to travel away from home to take a test. Another characteristic of a good distance-learning program is the __(61)__ of the distance-learning course with the same subject materials as those students taking the course on the home campus. The resultant diploma or degree should also be the same whether distance learning or on-campus study is employed.In the final analysis, a good distance learning program has a place not only for the __(62)__ students but also the corporation or business that wants to work in partnership with their employees for the educational benefit, professional development, and business growth of the organization. __(63)__ distance learning programs for their employees gives the business the advantage of retaining (保留) career-minded people while __(64)__to their personal and professional growth through education.50.A. experience B. break C. interest D. change51.A. process B. progress C. property D. possibility52.A.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)A Teacher’s LessonWhen Mrs. Thompson stood in front of her 5th grade class on the very first day of school, she told the children a lie. Like most teachers, she looked at her students and said that she loved them all the same.But that was impossible, because there in the front row was a little boy named Teddy Stoddard. Mrs. Thompson had watched Teddy the year before and noticed that he didn't play well with the other children, that his clothes were messy and that he constantly needed a bath. And Teddy could be unpleasant. It got to the point where Mrs. Thompson would actually take delight in marking his papers with a broad red pen, making bold X's and then putting a big "F" at the top of his papers.One day Mrs. Thompson was reviewing each child's past records and she put Teddy's off until last. However, when she reviewed his file, she was in for a surprise.Teddy's first grade teacher wrote, "Teddy is a bright child with a ready laugh...he is a joy to be around."His second grade teacher wrote, "Teddy is an excellent student, well liked by his classmates, but he is troubled because his mother has a serious illness and life at home must be a struggle."His third grade teacher wrote, "His mother's death has been hard on him. He tries to do his best but his father doesn't show much interest and his home life will soon affect him if some steps aren't taken."Teddy's fourth grade teacher wrote, "Teddy is withdrawn and doesn't show much interest in school."By now, Mrs. Thompson realized the problem and she was ashamed of herself. She felt even worse when her students brought her Christmas presents, wrapped in beautiful ribbons and bright paper, except for Teddy's. His present was clumsily wrapped in the heavy, brown paper that he got from a grocery bag.Mrs. Thompson took pains to open it in the middle of the other presents. Some of the children started to laugh when she found a rhinestone(人造钻石) necklace with some of the stones missing. But she stopped the children's laughter when she said aloud how pretty the necklace was and put it on.Teddy Stoddard stayed after school that day just long enough to say, "Mrs. Thompson, today you looked just like my Mom used to." After the children left she cried. From that very day, Mrs. Thompson paid particular attention to Teddy. As she worked with him, his mind seemed to come alive. The more she encouraged him, the faster he responded. By the end of the year, Teddy had become one of the smartest children in the class and, despite her lie that she would love all the children the same, Teddy became one her "teacher's pets."65. When Mrs. Thompson started teaching her 5th grade class, she thought Teddy was _______.A. bright and smartB. dirty and unpleasantC. quiet and shyD. sensitive and pitiful66. What did Mrs. Thompson learn from Teddy's past records from other teachers?A. Teddy had difficulty in learning.B. Teddy was not interested in school.C. Teddy changed for a reason.D. Teddy was born in a poor family.67. The underlined word “clumsily” is closest in meaning to_______.A. gracefullyB. carefullyC. especiallyD. awkwardly68. Which of the following can best explain the lesson Mrs. Thompson learned from Teddy?A.Warmth is the vital element for the growing plant and for the soul of the child.B. A life without love is like a sunless garden when the flowers are dead.C.It is the art of the teacher to awaken joy in difficult situation.D.The best teachers are those who don’t stop teaching when the bell rings.(B)69.The first email is basically an email of __________.A. apologyB. sympathyC. appreciationD. complaint70. What is the “spray” used for according to the passage?A. To repair the damaged boots.B. To protect the soles from heat.C. To prevent the crew from danger.D. To protect the boots from concrete.71. According to the president of The Shoe People, John Trimbald ________.A. can exchange the damaged boots with new ones at any timeB. must return the damaged boots to any of the retail storesC. will get new pairs of boots and a free year's supply of sprayD. can return the damaged boots and spray for a full refund now(C)People are looking for ways to reduce their carbon footprint. Purchasing property that is environmentally responsible is a good investment for those who are concerned about their own health and the well-being of the earth. Based on this trend, entire districts, known as eco-communities, are being designed with a green focus in mind. Dockside Green in Victoria, British Columbia is one of them.If everything goes according to plan, Dockside Green will be a self sufficient community along the harbour front of British Columbia's capital city. The community will be home to 2500 people and will consist of residential, office, and retail space. Builders of Dockside Green have the environment in mind with every choice they make. They ensure proper ventilation(通风), and guarantee residents 100% fresh indoor air. Building materials, such as paints and wood, are natural and non-poisonous. Eco-conscious builders use bamboo wherever possible because it grows fast and does not require pesticides(杀虫剂) to grow.Energy efficiency is one of the top concerns in eco-communities, such as Dockside Green. Not only do energy efficient appliances and light fixtures(照明设备) reduce the environmental impact of heating and hot water, they also save residents and business owners money. Dockside Green claims that home owners will use 55% less energy than average residents in Canada. Residents will have individual water metres as studies show that people use around 20% less energy when they are billed for exactly what they use. In addition, water is treated at Dockside Green and reused on site for flushing(冲洗) toilets.Planners of eco-communities such as Dockside Green must take the future into account. Dockside Green plans on reusing 90% of its construction waste. They also plan to continue using local suppliers for all of their transport and maintenance needs. This is a great way to reduce emissions(排放). Dockside residents will be encouraged to make use of a mini transportation system and buy into the community's car share program. Finally, plans are in the works for a high-tech heating system that will use renewable energy instead of fossil fuels (化石燃料).Dockside residents will benefit from excellent local services with high quality healthcare, shopping and education at the heart of the community, along with excellent recreation facilities and plentiful green open spaces. The Eco-Community will favour the use of locally-sourced goods and services; they will be desirable places to live, promoting a tangible(看得见的) sense of civic pride, responsibility and, as the name suggests, community.72. Which of the following is TRUE about Dockside Green according to the passage?A. It is an environmental charity aiming at reducing carbon footprint.B. It is a self sufficient community with a population of 2500 people.C. It is being built along the harbor front that is threatened by pollution.D. It emphasizes the importance of green energy and energy efficiency.73. Bamboo is a favorable choice for builders because it _________.A. provides good air circulationB. keeps pets outside the houseC. grows quickly and easilyD. does not produce any waste74. Which is NOT one of the issues Dockside Green hope to address in the future?A. Convincing local factories not to pollute the air.B. Creating an alternative to fossil fuels heating.C. Having people pay for individual household usage.D. Promoting the car share program to the residents.75. Which of the following is the best title for the passage?A. Ways to Reduce Carbon FootprintB. Green Energy: New Trends in CanadaC. Eco-Communities: Dockside GreenD. Wise Investment in Eco-CommunitiesSection CDirections:Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.a school newspaper can be a great learning experience and is a respectable thing to put on a resume(简历) in the future as it shows your interviewer your leadership skills and that could very well help land you the dream job for your future. Being part of the school newspaper will give you a good ideaalso it will give you a chance to learn what goes on in the school.the party, and that is authority. A teacher is there primarily to help make sure that everyone gets their articles in on time. With a teacher, staff simply feel an obligation to get their articles in. This really makes your job a lot easier. A teacher not only sees to it that articles are handed inUse your common sense for what's suitable for a middle school newspaper. Don't print anything hinting on weapons, violence, drugs, or basically anything that's illegal or not fit for middle school.Because most school newspapers have 12 articles, brainstorm 12. Some ideas are: games, colouring contest, short story, advice, random facts, sports, poetry or fashion. Once you have these articles planned out, open a word document and come up with cool titles and layout for your newspaper. You can copy a few things from the internet, but if it has a copyright, make sure to say where you got them from.Recommend to your staff that once they hand in their first article, get a head start on their next article because life consists of all things, e.g. sickness, vacation, family affairs etc. Also tell them to let you know if they can't get one article in so you can cover for them. Print off the schedule and give it to all your staff members.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.When the Internet powerhouse Yahoo wanted to teach ethics(道德标准) to its employees, it faced a challenge familiar to multinationalcompanies.Yahoo employs nearly 14,000 people at 25 sites worldwide. They wouldfeel bored at sitting down in front of a dated video in which actors with1980s haircuts tell them what to do. So it hired a company called The Network to design a game. In the game, the truck where Yahoo was founded traveled the world, turning into a boat and a helicopter along the way as it visited some of Yahoo’s forei gn offices. Participants play in game show-like scenarios(场景) that quiz them about conflicts of interest and doing business fairly. And employees note: Yahoo is tracking how well they do.Such activities draw more enthusiastic participation and teach more effectively than traditional methods. They are described as alternative-reality games (ARGs), involving both interactive and real-world elements. Besides teaching employees, ARGs have also been used in many areas for a number of different purposes.From a marketing perspective, a number of very successful ARGs have been written as a way to build product awareness. A very popular ARG called I Love Bees was produced to market the 2004 video game Halo 2. At its height, I Love Bees received between two to three million unique visitors over the course of three months.ARGs are more than just a fun way to learn. They have also been used to solve real world problems. An ARG called World Without Oil was created to obtain collective input from players about dealing with the world’s dependency on oil.World without Oil simulates(模拟) the first 32 days of a global oil crisis and anybody could play by creating a personal story that recorded the imagined reality of their life in the crisis. World Without Oil’s success on a small budget has opened the door for similar games to engage mainstream Internet users with climate change, education reform, governmental policy and other timely, vital issues.(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)81. What challenge did yahoo face in teaching ethics to its employees?82. In the game designed for yahoo, participants had to answer questions about ________.83. What are the three major functions of ARG mentioned in the passage?84. The success of World Without Oil suggests that ARGs can ________.第II卷(共45分)I .
