(1 point each ) Experiencing Culture Shock A When Eliza James arrived at the University of Xian, she was excited to live in a new country, to improve her Chinese, and to experience a culture so different from her own. But soon her excitement turned to frustration as she encountered one roadblock after another. “I felt like I couldn＇t accomplish anything. My dorm room had no heat, I couldn＇t get into the classes I wanted, and every time I asked someone for help they gave me the runaround. I felt like no one was listening to me.“ Eliza met with administrators, sent letters of complaint, and even contacted the consulate in Beijing, but she got nowhere. What Eliza didn＇t realize was that her American approach to solving problems was very different from the Chinese one in which patience and negotiation skills are key. She soon learned how to solve problems within the cultural norms of Chinese society instead of forcing her own values onto those around her. “I finally feel like I fit in and that I know what I＇m doing. In fact, it＇s really fun being in a place that＇s so incredibly different from what I am accustomed to.“ B Yoshi Yamamoto is a junior at a small college outside of Boston. Although he is an honors student now, Yoshi didn＇t always have such an easy time studying in America. “Teaching methods are very different here than they are in Japan. It took me a long time to get used to learning in seminars and discussing ideas with my classmates. At first it seemed like I wasn＇t actually learning anything.“ Yoshi＇s reaction was to totally withdraw: he didn＇t participate in class discussion; he spent lots of time alone in his room, and he even skipped class on occasion. “I thought I could teach myself. Now I recognize the value of the U.S. academic system, and I am able to adapt it to my own learning style.“ C Both Eliza and Yoshi experienced what is called culture shock: psychological disorientation due to living in a new culture. For many international students, studying abroad can offer exposure to new cultures and an opportunity to study new fields and languages. However, it also offers the greater challenge of trying to function in a foreign culture. Studying and reading about a certain culture is poor preparation for the reality of living in it. According to psychological studies, the four stages of culture shock are 1. euphoria, 2. hostility, 3. gradual adjustment, and 4. adaptation. Culture shock can be manifested in many ways: homesickness, boredom, stereotyping of or hostility towards the host culture, overeating or overdrinking, withdrawal, and inability to work effectively. D Different people experience different levels of culture shock and react in different ways. For example, Eliza got angry while Yoshi withdrew from society. The most important thing to remember is that culture shock is normal; it is not something to be ashamed of. Luckily, there are some things international students can do to make their adjustment to a new country go more smoothly. For instance, they can stay in touch with family and friends from home, join international student organizations, meet people from their own countries, and get involved in campus activities. Most importantly, they can adjust to life abroad by keeping a sense of humor and trying to remain positive.

(1 point each) Seasonal Affective Disorder: More than Just the Blues A Joshua dreads the winter months, not only because of the cold New England weather--the sleet, snow, wind, and rain--but because as the seasons change from summer to fall to winter, the days get shorter. As the days get shorter, he starts feeling depressed and irritable and spends more and more time at home, eating and sleeping. A graduate student in philosophy, Joshua finds that he gets little work done during the winter months and has trouble paying attention in class and concentrating on his research. “I soon realized that what I thought was just the ＇winter blues＇ was something more extreme than that.“ Josh visited a doctor who diagnosed him with SAD. B Seasonal Affective Disorder, or SAD, is a kind of depression that occurs seasonally. It is associated with the long hours of darkness and lack of sunlight during the winter months (people with SAD usually feel worse from December through February). Scientists don＇t completely understand the exact causes of SAD, but they believe it is related to a biochemical imbalance in the hypothalamus. The hypothalamus is the basic part of the brain that controls the body＇s breathing, heartbeat, metabolism, and hormone release. The effects of SAD include moodiness, irritability, low energy, increased appetite for carbohydrates (foods such as potatoes, rice, and bread), difficulty concentrating, and the tendency to oversleep. C Although doctors described SAD for the first time in 1984, humans have probably dealt with the disorder for thousands of years. It is not a coincidence that many cultures have important celebrations during the short days of the winter months. Christmas, Hanukkah, and Winter Solstice celebrations all occur in December. These celebrations involve lighting candles in order to bring light, warmth, and happiness to an otherwise depressing time of year. D So what can SAD sufferers do to feel better? Naturally, they need more light. For people who have mild cases of SAD, exercising in the morning sun could be enough to help them. Phototherapy, or light therapy, is usually prescribed for people who have more serious cases of the disorder. In light therapy, patients sit in front of a light box, a strong artificial light, for up to four hours a day. Phototherapy is effective in over 80% of SAD cases, and patients usually see results within three to four days. Although the symptoms of SAD are similar to those of clinical depression, traditional antidepressants have not proven useful in treating SAD. While psychological counseling cannot treat the symptoms of SAD, it is recommended to help SAD sufferers learn to accept and deal with their illness. 题目2 6.

Reading Comprehension (5 points) Read the passages, then answer the questions that follow. (1 point each ) Fast food can be good food Many people are too busy to prepare and eat three nutritious meals a day.so they turn to the convenience of fast-food restaurants. Many of the items at fast-food restaurants, snack bars, and food stands are fattening and not very nutritious.But fast food doesn’t have to be unhealthy.you can eat at fast-food restaurants and still eat well. Pay Attention to Calories and Fat Content By paying attention to the number of calories and fat that a food item has ,you can make smarter choices.Calories are “units for measuring how much energy a food will produce”.condsider two fast-food meals. A quarter-pound hamburger with cheese, jumbo-size fries,and a 16-ounce soda have a total of 1,535 calories and 76 grams of fat .a broiled (cooked under direct heat or over a flame )chicken sandwich ,a side salad with low-fat dressing,and a glass of water at the same fast-food restaurant have only 422 calories and 7 grams of fat .but maybe you really want a hamburger and fries .well,you can have a small hamburger,a small serving of fries,and a glass of water.At a total of 490 calories and 20 grams of fat,that’s still a much smarter choice than the large burger ,fries,and 20 grams of fat ,that’s still a much smarter choice than the large burger,fries,and sada. There’s More That You Can Do There are a few additional things you can do to make sure you eat well in fast food restaurantS.First of all,say “no” when the cashier asks you if you want to “supersize” you meal (order an extra large portion of each item).Second, ask for no mayonnaise or sauce,or ask for it on the side (in a separate dish).Third,substitute(use something instead of something else)healthy foods for fatty ones. For example,instead of ordering deep-fried tempura,order fresh vegetables.Instead of ordering a beef burrito with lots of cheese and sour cream,order a vegetable burrito with beans and rice.and don’t eat the chips!Another thing you can do is order a side salad or a vegetable soup and eat it first.That way,you will eat some vegetables,and you won’t be able to eat as much of your burger and fries.Fnally,eat slowly and stop eating when you’re full. It sounds simple,but many people keep eating even after they become full. 题目1 1.What is the main idea of this article ?________ 选择一项：C.

For example, Western foods are 6 damaging health in the industrialized island country of Japan. Instead of small meals of seafood, rice, and vegetables, the typical Japanese diet now includes large amounts of meat, dairy products, and desserts like tiramisu, a rich Italian dish full of chocolate, cheese, and sugar. According to Japanese health researchers, such 7 changes in eating habits are related to a great increase in health problems such as heart disease, strokes, cancer, and diabetes. On the other hand, the changing 8 global diet is having the opposite effect on the people in the CzechRepublic. The government of this European nation no longer supports meat and dairy products financially, so the cost of these foods is going up. In contrast, fresh fruits and vegetables are becoming more widely 9 available from private markets and stands. Cooks are even serving salads to schoolchildren, and families are eating healthier home-cooked meals. For these reasons, fewer Czech men are having heart attacks, the women are 10 losing a lot of weight, and most people are living healthier lives. Chapter 4 Exercise（分值7分 I.

(1 point each) These days, it’s getting easier and easier to find your way around. Some people have GPS devices in their cars to make sure they don’t get lost. GPS stands for Global Positioning System. These devices use satellites in space to “see” where you are and give you directions to where you want to go. And if you don’t have a GPS device, you can simply go online to get step-by-step directions. Websites like MapQuest.com and mappoint.msn.com can produce a map and directions in just a few seconds. But how do they do it? MapQuest® uses data (information) from a few different sources to produce directions and maps. Before MapQuest® went online, it sold regular paper maps in places like gas stations. The website uses the data from those paper maps, information from digital mapping companies, and government databases. At the moment, MapQuest® uses more than 30 computers to read all this data and provides users with millions of maps every day. In order to find the best route (way or path) from one place to another, MapQuest® first has to look at all possible routes. Then MapQuest® looks at each part of each possible route. It considers the types of roads on the different routes. Are they dirt roads, paved roads, freeways, or city streets? It looks at how many turns there are in each route and what kinds of turns they are. Are they right turns or left turns? It also considers the speed limit on each road and how many intersections there are. An intersection is “a place where two or more roads cross each other”. MapQuest® can also tell you how long your trip will take you. It does this by doing some math. MapQuest® bases its estimated driving times on the length and speed limit of each part of the route and the amount of time it probably takes to get through each intersection. For example, it allows more time for a left turn at an intersection than it does for a right turn. Someday, maybe we will have cars that can just drive us wherever we want to go, but for now, mapping websites make it a little harder to get lost. 题目2 6.What is the main idea of this article? 选择一项：C. How mapping websites work. 题目3 7.According to the article, MapQuest®______ 选择一项：D. starting by selling paper maps. 题目4 8.When you search for directions, the first thing MapQuest® does is_______ 选择一项：D. look at all possible paths. 题目5 9.When it’s deciding on the best route, MapQuest® probably chooses ________ 选择一项：C. freeways instead of dirt roads. 题目6 10.

However, few families now fall into this 6 category In fact, if more women decide to have children on their own, the single-parent household may become more 7 typical than the traditional family in many countries. Also, unmarried couples may decided to have more children—or they might take in foster children or adopt. And because people are staying single and 8 living longer (often as widows), there may be more one-person households in the future. On the other hand, some people 9 believe similar events happen again and again in history. If this is true, people may go back to the traditional 10 extended or nuclear family of the past. Others think the only certainty in history is changing: in other words, the structure of the future family could begin to change faster and faster—and in more and more ways.

These happy senior citizens, some of them over the age of 90, claim that the natural fruit juice cures—or at least decreases—the pain of their arthritis, a 6 disease of the joints of the aging body. It’s a folk remedy, not a proven medical therapy. Nevertheless, science is beginning to 7 figure out why sour cherry juice might work to improve the health of patients with arthritis. The secret is in the 8 substance that gives the cherries their dark red color. It belongs to a 9 classification of natural nutrients that color blueberries, strawberries, plums, and other fruits—and vegetables too. Moreover, these coloring substances may help to 10 prevent serious health disorders like heart disease and cancer. In other words, vitamins and fiber are not the only reasons to eat fruits and vegetables. “To take advantage of natural whole foods,” advise nutritionists. Chapter 8 Exercise（分值7分）I.

Reading Comprehension (5 points) Complete the following sentences by choosing the best from the answers A, B, C, or D. (1 point each) A Everyone makes mistakes, or so the saying goes. But have you ever heard about mistakes in Hollywood? When most people think of Hollywood, they think of blockbusters (very successful movies), high-paid actors, glitz, and glamour. But according to one Website, many Hollywood movies are full of mistakes. Some are technical errors. For instance, in a scene of the science-fiction adventure film The Matrix, when the main character steps out of his car, the viewer can clearly see the camera crew in the car window. In another scene, the same character is typing on his computer, yet the computer screen is blank. Other movie mistakes are historical. For example, the epic Gladiator, an Oscar winner, is known for having lots of historical errors. Throughout the movie, the gladiator Maximus refers to his home in Spain, and the other characters call him “the Spaniard.“ However, in 180 A.D., when the movie takes place, Spain as a country or even as a concept didn＇t exist yet. At another point in the movie, Maximus says that his homeland of Spain has “the best horses.“ But horses weren＇t brought to the Iberian Peninsula until the invasion of the Moors (North Africans) in 711 A.D, more than 500 years after the movie takes place. The historical drama Titanic, another Oscar winner, also has its share of historical blunders. The Titanic sunk in the year 1912. So why is one of the characters wearing a digital watch? In fact, movie watchers have found over 100 mistakes in The Matrix, Gladiator, and Titanic. Can you think of any errors in your favorite films? B How susceptible are you to advertising? Has a TV commercial or magazine ad ever made you buy the product that was advertised? If so, perhaps you have been subjected to subliminal advertising. Subliminal advertising is a kind of advertising that appeals to the subconscious. The word “subliminal“ comes from the Latin “sub“ meaning “lower,“ “beneath,“ or “under,“ and “limen“ meaning “threshold,“ (the level at which something begins to happen). Thus, subliminal advertising stimulates your brain at a level below conscious perception. You cannot see, hear, or perceive subliminal ads, but they may affect you just the same. ‎ ‎ There are two main types of subliminal ads. The first involves flashing messages quickly during a commercial or film. The messages appear and disappear so rapidly that the mind cannot process them consciously, but it might receive them passively, at a subconscious level. James Vicary, a market researcher, first introduced this kind of subliminal advertising in 1957 when he flashed the words “Eat Popcorn“ and “Drink Coca-Cola“ every five seconds during a movie. The messages couldn＇t be seen, yet Vicary claimed that the moviegoers＇ brains could perceive them: Coke sales went up by 18% and popcorn sales by over 50%. More recently, the same type of subliminal advertising was used in a negative ad for a political campaign. In the ad, the word “rats“ flashed up briefly during the part of the ad describing one party＇s healthcare plan. The purpose was to associate that opposing party with the negative word “rats.“ The second kind of subliminal advertising involves hiding or incorporating images into visual advertisements. A well-known example is on a package of a famous brand of cigarettes. Some say that if you look closely you can see the image of a man who is sexually aroused. In fact, a lot of subliminal advertising involves sex, coming from the idea that “sex sells.“ One media researcher claims that everything from crackers to alcohol to soda has used subliminal sexual imagery to appeal to buyers. Although studies show that consumers believe strongly in the power of subliminal ads, no one can prove the effects of subliminal advertising. Psychologists and others who study subliminal stimuli have not been able to show that subliminal advertising actually works. Many advertising researchers believe that traditional ads, in which a powerful image is used to sell a product, are ‎ more effective than subliminal advertising. All the same, it still remains a controversial topic, one that is on the mind of buyers and sellers alike. 题目6 6. What is the best title for the Paragraph A? 选择一项：B.

(1 point each) Meeting the ‎ Perfect Mate What is the best way to meet the perfect husband or wife? I am continuing to interview students on campus trying to answer this question for my sociology class. So far, people have mentioned arranged matches, discos and bars, computer dating services, and personal ads. One guy even said he thought supermarkets were the best places to meet women. I guess you can talk a lot about a head of lettuce! I decided to go to the school cafeteria to interview some people there. “I think date cafés are the best way to meet people,“ said my friend Rahul. “Date cafés? What＇s that?“ I asked. “Well, a date café is both a café and a dating service. You go to the café, order a cup of coffee or whatever you want, and look through people＇s profiles. Then, if someone interests you, you can send him or her an email and arrange a date at the café. You can also fill out your own profile and have people email you. The form asks you about everything from looks, to interests, to religion. The date café is a relaxed way to make contacts.“ “Are there many of them ‎ around?“ I asked. “Hmm. Well, there＇s one near campus called Drip. In fact, I had a Drip date just last week,“ said Rahul. “Drip! But isn＇t that a word that＇s used to describe someone who is dull and boring? It doesn＇t sound too promising.“ “Yeah, well it＇s funny you say that, because my date was pretty uninteresting. She barely talked at all, and she kept looking down at her coffee mug.“ “Well, what about a mail order bride?“ said Rahul＇s roommate, Joni. “A what?“ I asked. “A mail order bride. You know, you search for your wife in a catalog and the next thing you know you＇re married. With the Internet it＇s easier than ever,“ she said. “Ugh, that sounds awful.“ I said. “Have you ever met anyone who has done that?“ “Yes, my uncle did it. His marriage ended a year later. The truth is, I＇m against it. Usually the women come from poor countries and don＇t know what they＇re getting into. My uncle＇s wife had a really hard time adjusting and went back to her country as soon as they split up.“ “I think mail order is out. Any other suggestions?“ “I find ‎ that meeting people through classes or extracurricular activities is a good idea,“ said Michelle. “For instance, I signed up for a Japanese cooking class, both because I like Japanese food, and because I thought I might meet someone nice with similar interests.“ “And did you?“ “Yeah, I made lots of friends: Sumi, Katrina, Mariah...no guys, though. The class was 90% women. In fact, now that you mention it, the same thing happened with the salsa class, the pottery class and my Tai Chi class. I met a lot of nice women, but I definitely did not find the man of my dreams.“ Last I interviewed a couple in the library. “Friends“ they said. “We met through friends. It＇s the best way to find the perfect mate.“ “Really,“ I said. “And why is that?“ “Well, your friends usually know what you like. And also, you know the person is someone you can trust, not like meeting someone in a bar or a supermarket. For instance, we met because Chris＇s lab partner thought we would really get along.“ “Yeah, Scott and I met, and I immediately liked ‎ him. I emailed him and it took him three months to email me back!“ “Well, I＇m a little shy, but it eventually worked. Here we are, a year later and still together.“ “Well that＇s the best story I＇ve heard yet, “ I said. But if I＇ve learned one thing in this study, it＇s that meeting someone special, no matter how you do it, is difficult.“ 题目2 6.If you interview someone, you __. 选择一项：A. ask him/her a lot of questions 题目3 7.

Choose “T” for True and “F” for False. (1 point each ) 题目1 Competition in Olympic sports is supposed to be fair. However, in judged sports, fairness is impossible. Therefore, judged sports should be ‎ banned from the Olympic games. A judged sport is any sport that requires judges to determine a winner. For example, gymnastics, figure skating, half pipe (snowboarding), and diving are all judged sports. 1.The writer believes judged sports should be eliminated from the Olympics. 选择一项：A. T 题目2 Why do I believe that judged sports should be eliminated from the Olympics? First of all, judges don’t see everything. For example, a mistake in figure skating can happen in a fraction of a second. If a judge blinks or looks away for a moment, he or she might miss the mistake and give the skater a higher score than the skater deserves. 2.One reason that judged sports should not be allowed in the Olympics is that judges can have different opinions. 选择一项：B. F 题目3 Second, two judges can disagree about which athlete gave the best performance. In sports in which the difference between gold and silver is usually a few hundredths of a point, this kind of subjectivity is unacceptable. Can anyone really say with certainty that a gymnast who receives a score of 9.825 is a ‎ better gymnast than one who scores 9.823? 3.One argument against banning judged sports from the Olympics is that people should stop arguing about it. 选择一项：B. F 题目4 A lot of people claim that judged sports are subjective and should not be allowed in the Olympics. They feel that only sports that are measured objectively for things like speed, such as swimming, track, and skiing, should be allowed because judges can’t be objective and fair. I disagree with these people. Why? I believe that no sport is 100% fair and objective. 4. The writer here believes all sports are objective. 选择一项：B. F 题目5 Some athletes may win because their equipment is better than their opponents’ equipment. For example, in the 2000 summer Olympics, some swimmers wore controversial high-tech suits. The maker of the suit claimed that the fabric could make a swimmer 3% faster. No one could prove that this was true, but they couldn’t prove that it wasn’t true either. 5. The equipment can be one reason that decides athletes’ sports scores. 选择一项：B. F 题目6 II.
