But if you’re one of those people who can’t stop snapping photos at an important event, beware-you could end up fo rgetting it all in a flash.Experts have warned that the addiction to recording every moment of our lives could be having an adverse effect on our m emories.Maryanne Garry, a New Zealand psychology professor, has been studying how the frequent taking of photos might change childhood memories. “I think the problem is that people are forgetting to experience the moment,” she says. Parents at the park taking one photo after another of their children, for example, are actually paying less attention to what is happening around the m. The picture only captures a small party of the total experience. And because parents remember less about these important ev ents, they become less effective in their role as the key people who help children learn how to talk about their experiences. As a result, children‟s own childhood memories are reduced.The idea that we are experiencing less as we record more got psychologist Linda Henkel thinking. She wanted to explore h ow photographs shape our memories.Henkel, who researches human memory at Fairfield University in Connecticut, did an experiment by sending groups of students to the university’s art museum. The students observed some objects and photographed others. Then, back at the laboratory, th ey were given a memory test. Henkel found what she called a “photo-taking effect”. The students remembered fewer of the obje cts that they had taken photos of, and they remembered fewer details about those objects. She says her students’ memories were worse because they were relying on the camera to remember the details for them.“As soon as you hit …click‟ on that camera, it’s as if you’ve outsourced your memory,” she says.26. The underlined word “it” in Paragraph 1 refers to __________.A. an important eventB. a child‟s birthdayC. A valuable photographD. A family holiday27. According to Garry, what will be the result of parents frequently taking photos of their children?A. Parents will be very skillful at taking photos.B. Children will enjoy many more beautiful pictures.C. Parents will appreciate these important moments less.D. Children will become more important in their parents’ eyes.28. According to Paragraph 3, why are children‟s memories reduced?A. Flash lights are causing children to forget more things.B. Parents are not interested in listening to children’s experiences.C. Children are more interested in taking photos than experiencing.D. Parents are less effective in helping children discuss their experiences.29. How did Henkel develop her theory about the “photo-taking effect”?A. By carrying out an experimentB. By giving a questionnaireC. By interviewing a group of studentsD. By researching the findings of the others30. What‟s the purpose of this passage?A. To introduce a new discovery in taking photos.B. To discuss the effect of photo-taking on memory.C. To explain how to use cameras in an effective way.D. To describe the ways of remembering valuable experiences.BThe human body is an amazing machine. It’s tough, and we usually recover from illness or injury on our own, without the help of a doctor. But what happens when we need medical treatment? In the past, some people went to a hospital to see a medic al doctor. Others preferred traditional treatments, such as herbal medicine or acupuncture (针灸).These two types of medicine-one modern and Western and the other ancient and Eastern-used to have nothing to do with e ach other.In recent years, however, people have begun combining both modern medical science and more traditional treatments. This new kind of medicine is often called integrative medicine because it integrates, or combines, different types of medical approac hes. Some of the principles of integrative medicine include preventing illness by helping people stay healthy, integrating differe nt types of treatments according to patient needs, and considering the health of the whole person rather than concentrating on a particular illness or injury.One health organization in America has opened its Integrative Medicine and Wellness Center. At the center, members are offered different services. Those suffering backache can try massage to relax their muscles and encourage the flow of healing ene rgy in their body. Those with allergies are helped to develop their body‟s natural resistance. And those who aren‟t ill, but want to improve their strength and focus their mind, take tai chi or yogo classes.Integrative medicine patients appreciate having an alternative to surgery or to drugs and their harmful side effects. They a lso enjoy activities and treatments that make them feel better even if they are not sick. And economically, preventing illness is much less expensive than a hospital stay.According to Dr. Andrew Weil, founder of the Program in Integrative Medicine at the University of Arizona, integrative m edicine combines the best parts of Western medicine with traditional therapies. And because both doctors and patients are worki ng to prevent illness, they become partners with the same goal instead of strangers who see each other only when the patient is sick.31. Which of the following is the best title of this passage?A. Western medicineB. Acupuncture and herbal medicineC. Changes in medical educationD. Combining modern and traditional medicine32. By using the underlined statement “preventing illness by helping people stay healthy” in Paragraph 2, the writer wants to _.A. provide advice on how to stay healthyB. describe a principle of integrative medicineC. recommend modern medicine over traditional medicineD. explain why some people doubt the effectiveness of new treatments33. Which of the following is an example of integrative medicine?A. Having a heart operation.B. Taking a pain killer for a headache.C. Using herbal treatments after an operation.D. Having herbal medicine and acupuncture.34. Which is NOT mentioned as an advantage of integrative medicine?A. Patients take actions to avoid getting ill.B. It costs less than medical care in hospitals.C. Patients have more choices in terms of treatment.D. Doctors are able to carry out more medical research.35. According to Dr. Weil, with integrative medicine, __________.A. the doctor gives the orders and the patient follows passivelyB. doctor and patient see each other occasionally if there is a problemC. doctor and patient work together so that the patient does not become illD. doctor and patient perform the same role in providing medical treatmentCThe old man fished alone in a small rowboat and he had gone eighty-four days now without taking a fish. In the first forty days a boy had been with him. But after forty days without a fish the boy’s patents had told him that the old man was now bad l uck, and ordered the boy to join another boat, which caught three good fish the first week. It made the boy sad to see the old ma n come in each day with his boat empty and he always went down to help him carry in the fishing lines or take down the old, pa tched sail.“Santiago,” the boy said to him as they dragged up the boat to the sand. “I could go with you again. I’ve made some mone y.” the old man had taught the boy to fish and the boy loved him. “No,” the old man said. “You’re with a lucky boat. Stay with t hem. You must obey your father.”“We can be lucky again too. Remember when we didn’t catch a fish for 10 days, then caught a big one each day for a month?” said the boy. “Can I offer you a beer on the balcony and then we’ll take the stuff home,” said t he boy. “Why not?” the old man said.“Santiago,” the boy said as they sat on the balcony, “If I cannot fish with you, I would like to serve in some way.”“You bo ught me a beer,” the old man said, lifting the bottle to his mouth. “Do you remember the first time I took you out to fish?” the ol d man asked. “I was five. I remember the tail of a huge fish slapping against the boat, the noise of you clubbing him and the sw eet blood smell. I remember everything from when we first went together,” the boy said. The old man looked at him with his su n-burned, loving eyes.“May I get some sardines for tomorrow? Let me get four fresh ones,” said the boy. “One,” the old man said. His hope an d his confidence had never gone. But now they were freshening like a sea breeze. “Two,” the boy said. “Thank you,” the old ma n said. He was too simple to wonder when he had attained modesty. But he knew he had attained it and he knew it was not disgr aceful and it carried no loss of true pride. “Tomorrow is going to be a good day with this wind,” he said. “I will row far out befo re it is light. There will going to be a good day with this wind,” he said. “I will row far out before it is light. There will be a bigfish?” asked the boy. “I think so. And I know many tricks.”36. When did the boy stop working with the old man?A. 40 days ago.B. 44 days ago.C. 80 days ago.D. 84 days ago37. Why was the boy forced to stop working for the old man?A. It was too dangerous to continue fishing.B. It was time for the boy to return to school.C. The old man was thought to be a poor teacher.D. The boy couldn’t earn enough money with the old man.38. In paragraph 2, the boy probably mentioned their past fishing experiences in order to __________.A. convince the old man that he should not retireB. explain why he had to stop working for the old manC. persuade the old man to let him return as his assistantD. warn the old man about the danger of fishing in the deep sea39. Which of the following did the boy NOT do for the old man?A. Buy him a beer.B. Repair the sail.C. Drag up the boat.D. Take in the fishing equipment.40. What can we lean about the old man from the last paragraph?A. He remained optimistic about catching fish.B. He was the most skillful fisherman in the village.C. He would stay out longer than any other fisherman.D. He would usually go out further than any other boat.DAt the start of the 20th century, a new city was beginning to grow on some flat land near the sea in southern California; its name was Los Angeles. At the same time, a new industry was just being born: the cinema.America’s movie industry began life in New York; but by 1910, movie-makers were moving to Los Angeles. In New York, e verything was too expensive: workers, land, taxes. Moreover, it was difficult to make movies in winter, because it was too cold. The Los Angeles region, on the other hand, was full of advantages. In California, they could make films all through the year; an d everything was cheaper. In particular, there was lots of land for sale, especially in the Los Angeles suburb called Hollywood. Movies quickly became very popular, and this popularity exploded after “talkies” first appeared in 1925. Nevertheless, movies were expensive to produce, and film companies needed money-lots of it. For this reason, Hollywood rapidly became controlled by a small number of big companies such as MGM, 20th Century Fox, Warner Bros. and Paramount. Since then, the big compa nies fortunes have ebbed and flowed, but most of them are still there. Some old names have disappeared, but some new ones ha ve appeared, companies like Walt Disney and Steven Spielberg’s company Amblin. Today the biggest studios belong to huge int ernational firms. For instance, News Corporation, which now owns Fox, also owns newspapers on three continents, and TV net works in America, Europe and Asia.It is only huge companies like Fox that can afford to make today’s very expensive films; and for Titanic-at the time the mo st expensive film ever mad-Fox had to get help from another big company, Paramount!Once Hollywood mad films just for America; today it makes them for the world. It’s the center of a global dream-machine. Perhaps we dreamed differently in the past. Today, thanks in part to Hollywood, people everywhere have similar dreams.We now live in the age of global culture. Hollywood did not invent this culture-but for better or for worse, it has become o ne of the most powerful elements in it. Like it or not, we all now live on planet Hollywood.41. What attracted the film industry to Los Angeles?A. Cheaper costs and pleasant weather.B. More talented actors and mild climate.C. More skilled workers and plentiful land.D. Large movie companies and lower wages.42. Why did a few companies come to control the American film industry?A. They were already experienced in film production.B. They were able to employ the most creative people.C. These companies were the first to make talkie films.D. Small companies could not afford the film production costs.43. The underlined “ebbed and flowed” in Paragraph 5 is closest in meaning to __________.A. improved rapidlyB. gone up and downC. remained very stableD. worsened gradually44. Which of the following is true about the Hollywood movie companies?A. They sometimes work together to produce movies.B. They produce expensive movies far less often than in the past.C. The same companies have controlled the industry for almost 100 years.D. There are many large companies competing against each other for success.45. What does the writer think about the international influence of Hollywood?A. It has encouraged people to dream like Americans.B. It has made foreigners love American people more.C. It has become a driving force in shaping global culture.D. It has damaged the local film industry in other countries. 第二节信息匹配（共5小题；每小题2分，满分10分）第二节读写任务（共1小题，满分25分）阅读下面的短文，然后按照要求写一篇150词左右的英语短文。
