Exercise 1Section AQuestions 1 and 2 will be based on the following news item.How do you choose a college? Some of you might choose a school based on the courses that it offers. Some might choose one that’s close to home, or really far away. [1] But how about for a money-back guarantee? Lansing Community College in Michigan is offering that deal to some students. If you take certain classes, and if you don’t get a job within one year after you finish, you can get your money back! There is some fine print to this. You can’t miss any classes, you have to do all your assignments and you have to prove that you’ve been looking for a job. It’s an interesting idea, [2] especially in a state whose unemployment rate is nearly 12 percent.1. What may be the advantage for Lansing Community College?2. What is the unemployment rate in Michigan?Questions 3 and 4 will be based on the following news item.Well, we’re taking you to Australia next today, where [3] the state of Queensland in northeast Australia is struggling through the effects of a powerful hurricane. If Queensland sounds familiar, this same region was hit with serve flooding recently. This time, the disaster is Cyclone Yasi. Yasi could be one of the worst hurricanes Australia has ever seen. We want you to look at this video. You can see what looks like a sign that got blown down, flying through the street, being ripped apart. [4] People in Queensland were warned about Yasi a few days ago, so they had some time to get ready. But one official said it could be a tough couple days.3. What are the Australians suffering from?4. What can we learn about Yasi from the news?Questions 5 to 7 will be based on the following news item.India is home to more than 1.2 people and second only to China’s population. Because of that huge population and the fact that it’s a federal republic like the U.S. India is often called the world’s largest democracy. India’s population is also young. [5] Its median age is 27 years old. In the U.S. that age is closer to 37.It’s no wonder why so many Indians who are close to the voting age of 18 are realizing they have political power. This is something that country’s politicians are noticing, too. Many young people are first time voters. [6] Given that Indian’s youth makes up half of its billion plus population, how India’s young vote will determine the country’s future.They are obviously really frustrated with current political situation in their country. The only government these youngster have really known is the current Congress party Led One, which is in power for the last ten years. [7] During that time, prices have risen sharply. The price of petrol is doubled. Some young people are going to vote for a different party, one that will fight inflation and will take firm action to control inflation in the difficult global economy.5. What is the median age in India?6. What can we learn about the young people in India?7. What is the largest current economy problem in India?Section BConversation OneQuestions 8 to 11 are based on the conversation you have just heard.W: [8] Good morning, and welcome to this week’s Business World, the program for and about business people. Tonight we have Mr. Steven Kayne, who has just taken over an established bicycle shop. Tell us, Mr. Kayne, what made you want to run your own store?M: Well, I always loved racing bikes and fixing them. [9] When I was working full-time as a salesman for a big company, I seldom had time to enjoy my hobby. I knew then that as soon as I had enough money to get my own business going, I’ll do it. I had my heart set on it and I didn’t let anything stand in my way. [10] when I went down to the bank and got a business loan, I knew I’d love being my own boss. Now my time is my own. I open the store when I want and leave when I want.W: You mean you don’t keep regular hours?M: Well, the sign on my store says the hours are ten to six, but if business is slower than usual, I can just lock up and take off early.W: Have you hired any employees to work with you yet?M: Yeah, [11] a couple of friends of mine who love biking as much as I do. They help me out a few days a week. It’s great because we play cards or just sit around and talk when there are no customers.W: Thank you, Mr. Kayne. We wish you success in your new business.8. What is the woman doing?9. What did Mr. Kayne do before he took over the bicycle shop?10. Why did the man take over a bicycle shop?11. What do we learn about the people working in the shop?Conversation TwoQuestions 12 to 15 are based on the conversation you have just heard.W: Well, [12] the main activities in the region were historically steel and paper processing, I think.M: Yes, but I’m not quite sure about the status of those industries now. could you tell us something about that?W: Yes, of course. [13] In fact, they are less significant, but steel-related manufacturing still accounts for 44% of industrial activity. So it’s still very important. In fact, 80% of Spain’s machine tools are from the Basque Country. As for paper processing, there’s still a little. Butit’s no longer what it once was in the region. So, is that clear?M: Yes, thanks.W: Now, to get back to what I was saying, there’s a lot of unemployment as well as geographical problems in the region.M: Sorry, Victoria. What do you mean by geographical problems?W: Well, what I mean is the area is very hilly, mountainous in parts. [14] So there used to be transport problems. Now though there are new train links and better roads, but it may be that some smaller towns inland remain not very well connected, is that OK? Does that make sense?When we talk about specific location suggestions for the factory, we’ll see this in more detail, so we’ll come back to this question, OK?M: OK, right.W: [15] So I was about to say something about the workforce in the region and the level of training and education. In general, it’s very good and improving.12. What was one of the main industrial activities in the region?13. What does the woman say about steel-related manufacturing in the region?14. What problems hinder the region’s development?15. What will the speakers discuss later?Section CPassage OneQuestions 16 to 18 are based on the passage you have just heard.[16] I first met Joe Gans shen we were both 9 years old, which is probably the only reason he is one of my best friends. If I had first met Joe as a freshman in high school, we wouldn’t even have had the chance to get to know each other. Joe is a day student, but I am a boarding student. We haven’t been in the same classes, sports or extracurricular activities. [17] Nonetheless, I spend nearly every weekend at his house, and we talk o the phone every night. This is not to say that we would not have been compatible if we had first met in our freshman year. Rather, we would not have been likely to spend enough time getting to know each other, due to the lack of immediately visible mutual interests.In fact, to be honest, I struggle even now to think of things we have in common, but maybe that’s what makes us enjoy each other’s company so much. When I look at my friendship with Joe, [18] I wonder how many people I’ve known whom I never disliked but simply didn’t take the time to get to know. Thanks to Joe, I have realized how little basis there is, for the social divisions that exist in every community. Since this realization, I have begun to make an even more determined effort to find friends in unexpected people and places.16. Why does the speaker say Joe Gans became one of his best friends?17. Where does the speaker spend most of his weekend?18. What has the speaker learned from his friendship with Joe?Passage TwoQuestions 19 to 21 are based on the passage you have just heard.It was a bad night for Louis. His research in the neighboring town had taken longer than he expected. It was late and he was very tired when he drove home. [19] He turned into his building’s parking lot, but all the spaces were full. He drove back out onto the street looking for a parking space. The first block was full. The next block was almost empty. Louis didn’t see a no-parking sign, but he suspected that if parking were allowed there, most of the spaces would be filled. Then he saw a small parking lot with two free spaces. He was so glad to see them that he didn’t even think to read the sign by the entrance. He drove in , parked, and hurried home to go to ed. [20] The next morning he went back to the lot to get his car. It was gone. He run home and telephoned the city police to say that his car had been stolen. It took the police only a minute to tell him what had happened. His car had been on a private lot. It had been taken away by the police. [21] Louis had to take a taxi to the city garage far from the center of town. He had to pay a fee of $40 to get his car back. In addition, he got a parking ticket —his first one ever in Greenville.19. Where did Louis intend to park his car when he came back from work one night?20. What did Louis think had happened to his car the next morning?21. Where did Louis finally get his car back?Passage ThreeQuestions 22 to 25 are based on the passage you have just heard.[22] Well, to pick up where we left off last time, I believe we agreed that creativity is a mysterious idea. It’s one of those things we all recognize when we see it. But we don’t really understand what it is. We seem to feel that some people are naturally creative, but we don’t know how they got that way. Is creativity a natural gift like good looks? Or is it something that can be acquired like knowledge? Perhaps if we analyze the creative process carefully, we might get some insight into what it is and how it might work in our lives. [23] The creative process has always been accepted as the source of all important work in the arts. But we should not think the creativity plays a role only in the arts. [24] Every major scientific discovery began with someone imagining the world to look differently from the way others saw it. And this is what the creativity is all about: imagining the world in a new way. And despite what you may believe about the limits of your own creative imaginations, we all have the potential to imagine the world in an absolutely new way.In fact, you were born with it. It is your birth right as a human being. [25] And what’s more, you use it every day, almost every moment of your life. Your creative imagination is what you use to make sense of your experiences. It’s your creative mind that gets meaning from the chaos of your experiences and brings order to your world.22. What did the speaker most probably discuss last time?23. What is a widely accepted idea about the creative process?24. What leads to major scientific discoveries according to the speaker?25. What does the speaker imply about the creative process?。

Case Study 1-1: Multiple Health Problems
Secondary to Injury
D.S., a 28-year-old woman, was treated for injuries sustained in a train derailment accident. During the course of her treatment, she was seen by several specialists. For pain in her knee and hip joints, she was referred to an orthopedist（整形外科医师）. For migraine headaches（周期性偏头痛）and blurry vision（视力模糊）, she consulted a neurologist（神经科医师）. For pain on urination （尿）nd occasional bloody urine, she saw a urologist. Later, for a persistent dry cough and problems resulting from a fractured nose, she was referred to an otorhinolaryngologist（耳鼻喉医师）. During her initial course of treatment, she had a CT scan of her abdomen（腹部）and brain and an MRI of her hip and knee. Both imaging studies required her to lie motionless on her back for 45 minutes. Several months after the accident, D.S. was still experiencing some discomfort, and she decided to investigate alternative therapies. She made an appointment with a naturist practitioner who specialized in homeopathy（顺势疗法）and herbal medicine. Before her appointment, she browsed in the Nutra-Medica Shop, which carried nutritional supplements, vitamin and mineral products, homeopathic remedies（顺势治疗药）, and herbal formulas. She planned to ask the therapist about some of the products that she saw there, which include remedies with the trade names Pneumogen, Arthogesia-Plus, Renovite, Nephrostat, and
Hematone.
