People use them on trains, airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.Westlake College in Virginia will start a laptop computer program that allow students to do schoolwork at anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million 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 teachers, their classmates, and their families. However, the more important of the laptop program is that students will be able to use computers without going to a computer lab. 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, laptops used in higher education, such as colleges and universities, are workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the 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 teachers to use computers in their lessons. As one Westlake teacher said, “ Here we are in the middle of Virginia and we have given students a window on the world. They can see everything and do everything.21. 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 libraries22. Why is the word “speak” in the se cond paragraph in quotation marks?A. They don’t really talkB. They use the computer languageC. Laptops have speakersD. None of the above reasons is correct.23. Which of the following is true about Westlake College?A. all teachers use computersB. 1500 students have laptopsC. it is an old college in AmericaD. Students there can do everything24. A window on the world in the last paragraph means that students can ----------.A.attend the lectures on information technologyB.travel around the worldC.get information from around the worldD.have free laptops25 What can we infer from the passage?A. The program is successfulB. The program is not workableC. The program is too expensiveD. We don’t know the result yetBMost people feel lonely sometimes, but it usually only lasts between a fewminutes 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 years. Now researchers say there are three different types of loneliness.The first kind of loneliness is temporary. 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 or a particular situation---- for example, a 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) loneliness usually last 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 lone people think there is little or nothing they can do to improve their condition.Psychologists agree that one important fact in loneliness is a person’s social contacts, e.g, friends, family members, co-workers,, etc. We depend on 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 lone people may have many social contacts, they sometimes feel they should have more. They question their own 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 a normal, healthy part of life, chronic loneliness can be a very sad, and sometimes dangerous condition.26 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 guidance27 “ It ” in the last sentence of the second paragraph refers to ----------.A. temporary lonelinessB. situational lonelinessC. a new placeD. sleeplessness28 The topic of the 4th paragraph is that _______________.A.one problem of loneliness is a person’s social contactsB.we depend on various people for different reasonsC.lonely people don’t have many social problemsD.lonely people don’t have many friends29 Why do psychologists want to help chronically lonely people?A. Chronic loneliness can cause family problemsB. Chronic loneliness can cause serious illnessC. Chronic loneliness cannot be overcomeD. A, B, and C are all correct30 What is the best title of the passage?A. Three kinds of LonelinessB. Loneliness and DiseasesC. Loneliness and Social ContactsD. Chronic LonelinessCI came to study in the United States a year ago. Yet, I did not know the real American society until I was injured in a car accident because after the car accident I had to see a doctor---- and go to court.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. And only a good doctor can help me get a good lawyer. Now that he had helped me find a good doctor, it was only fair that I should pay him.But every time I want to see 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. Y et 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 seeingme 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 him. And he made pay him $770.Now I had to act as my own lawyer. Due to my inexperience, I told the insurance(保险) company the date I was leaving America. Knowing that, they played for time, ….. and I left without getting a cent.My experience taught me two things about America: firstly, in a country like America money is everything. It is more important than friendship, honor or professional morality(职业道德). Secondly foreigners are still being treated unfairly. So when we talk about America, we should see both its good and bad sides.31 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 lawyer32. A good doctor is essential for the author to ______.A. to be properly treatedB. talk with the person responsible for the accidentC. recover before he leave AmericaD. eventually get the responsible party to pay for his injury33.The word “charge” in this passage means ______.A. be responsibleB. accuseC. ask as a priceD. claim34 Both the doctor and the lawyer in the passage are very ______.A. friendlyB. greedyC. professionalD. busy35 What conclusion can you draw from the story?A . Going to court is something very common in AmericaB . One must very careful while driving a carC . There are more bad sides in America than good sidesD .Money is more important than other things in AmericaDThe Taj Mahal (泰姬陵) is a love story, a sad and beautiful one. If it didn’t exist, we would easily imagine that the story of its construction was simply a fairy tale. Three hundred years ago, there lived an Indian emperor called Shah Jahan. His wife was a beautiful and bright woman whom he loved greatly. Her title was Mumtazl Mahan: its shortened form Taj Mahan, means “pride of the palace”. In the year 1630 this beloved wife of the emperor died. He was so brokenhearted that he thought of giving up his throne. He decided out of his love for his wife, to build her the most beautiful tomb that had ever been seen.He called in the best artists and architects from India, Turkey, Persia and Arabia and finally, the design was complete. It took more than twenty thousand men working over a period of 18 years to build the Taj Mahan, one of the most beautiful buildings in the world.The building itself stands on a marble platform 29 meters square and 6-7 meters high. Towers rise from each of the four corners. The Taj itself soars another 61 meters into the air. It is an eight-sided building made of white marble.The emperor planned to build an identical tomb of black marble for himself on the other side of the river connected by a silver bridge. However his son put him into a prison in the palace before he could finish, and for the rest of his life, he could only gaze across river at the tomb of his beloved wife.36.

Which of the following statements is NOT true about the Taj Mahal?A. It was completed quickly owing to the efforts of the best artists and workers.B. A lot of people took part in the building workC. It is a magnificent building.D. It is a tomb for the emperor’s beloved wife.38.

The emperor _____________.A. died soon after Taj Mahan diedB. was killed by his sonC. was beloved by his peopleD. died after 1648ECelebrations spread across China when Shanghai, the Oriental Pearl, was given the right to host the 2010 World Expo(世博会) on December 3.Shanghai won the honor after beating rivals from Russia, Mexico, Poland and South Korea.“I’m very proud of being Chinese,” said Wang Kaibo, a Senior 2 student of the Middle School Affiliated(隶属) to Be ijing Medical University. “The winning of the expo is a victory, not only for Shanghai residents, but for the people of the whole Chinese nation.”Bidding(申办) for the expo shows that China is more confident of playing a more important role on the inter national stage. It’s competing for large events and the next one could be the World Cup, Wang said.The World Expo 2010 and the 2008 Beijing Olympics will become the twin shining stars of China’s development over the next 10 years, said experts.Th e World Expo is known as “Olympics of the economic, cultural, scientific and technological fields.” It is usually held every five years and lasts for six months.The Olympics, World Cup and World Expo are considered three top international events in the world. China is the first developing country to win the expo bid in theevent’s 151-year history. Not only will it attract more foreign investment to China, but experts say that the half-year-long exhibition will bring at least 70 million visitors to Shanghai.The World Expo is a great event for different countries to exchange social, economic, cultural and scientific achievements, and also help to encourage new technology and ideas. The expo was first held in London in 1851. It has a history of global influence. The Eiffel Tower, built during the Paris World Expo in 1889, became the symbol of the French capital. Many historic inventions, such as the telephone and airplane, all made their first appearance at a World Expo.40. What does the underlined w ord “rivals” probably mean in the second paragraph?A. competitorsB. enemiesC. playersD. supporters41.

10.A(“取名自白乐天的《池上》诗”错)
附:文言文参考译文
已故魏国忠献公韩琦在自己府第的池塘之上建造了一座厅堂,取名为“醉白”。
选取白居易《池上》一诗,作醉白堂歌。
意思好像是羡慕白居易并且认为自己有不及白居易的地方。
天下士人,听说后心生怀疑,认为忠献公已经无愧于商代的伊尹和西周的周公旦,却还羡慕白乐天,是为什么呢?我听了这些士人的议论感到好笑:忠献公哪里只是羡慕白乐天啊,人家忠献公正想做一个普通人却得不到。
老天生出这个人,将要让他担当天下重任,那么受冻的人找他求衣穿,挨饿的人找他要饭吃。
凡是不能满足的都想要得到满足。
如果有谁能够帮助他们,那他将穷于应付。
因此他将一辈子处在辛勤劳苦之中,遭遇各种利害冲突,这难道是人所愿意做的吗?
忠献公已经辅佐三个皇帝治理国家,晚年萌生告老还乡的强烈愿望,可是大家一起挽留他继续任职,他不能够放弃。
在这个时候,他对白乐天有羡慕的感情,是不值得奇怪的。
但是把白乐天平生行事和忠献公比较,人生收获的大小多少,那么后世的评论,相信一定会公允无欺。
忠献公的文才治理天下太平,武功平定叛乱,韬略使国家安定,却不居功自傲。
渴求贤才,看轻爵禄,而世人并不知道他的恩德。
征战果断勇敢,安定六军。
遥远边陲地域的人也仰慕他的风采,而国家安危系于一身。
这些都是忠献公做到的,而白乐天没有做到。
在自己身体强健时乞求告老还乡,退隐田园十五年,每天和朋友们饮酒赋诗,尽享山水田园乐趣。
家里有穿不完的布帛,吃不完的粮食,歌舞作乐享受不尽。
这些就是白乐天所拥有的,而忠献公享受不到的。
忠诚言论,美好计谋,为国家效劳,而且灿烂文采在后代显露;处境困穷,不改变操守,道德人品比古人还高,这些方面忠献公和白乐天都是相同的。
忠献公既不因为自己所拥有的而自夸,也不因为自己所缺少的而自卑。
只是推求与白乐天相同的情趣作为寄托。
当他在一醉之中寄托自己的情怀,看淡得失,忘记祸福,混淆贵贱,等同贤愚,等同世间万物,完全融入自然之中,并不仅仅是自比于白乐天而已。
古代的君子,他们对自己要求繁多,对个人身名要求低廉。
因此他们实际才能超过名声,因而世人对他们的美德盛赞不厌。
圣人如孔子,却把自己比为老、彭,等同于左丘明,自认为不如学生颜渊。
后世君子,他们的实际才能不能达到,可是都有奢求名声的愿望。
扬雄自比为孟轲,崔浩自比为张良,然而后世人始终不赞同他们。
由此看来,忠献公之贤能比他们要高出很多。
过去忠献公曾对他儿子忠彦说,想求我为醉白堂写一篇记没有实现。
死后,忠彦告诉我,我认为自己义不容辞,于是流着泪写了这篇记。
