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?。

7.不可思议的C语言程序。
C语言程序可编写得非常晦涩难懂,以下就是一些例子。
尝试运行下面的部分程序,了解它们是干什么用的。
如果你无法读懂源程序是怎么产生这样的结果的,请不要问老师,因为老师也读不懂这些程序。
有时间的话就自己慢慢琢磨吧。
等你琢磨明白后如果能给老师讲一讲的话,老师会非常高兴的。
(1)打印“hello, world”。
和我们的第一个题目干同样的事情,却可以用很复杂的方法实现。
比如程序 helloworld1984.c 和helloworld1986.c
(2)汉诺塔问题。
程序ejb_ioccc1993_Hanoi.c 需要你输入一个数字(几个盘子);另一个程序vanschnitz_ioccc1995_Hanoi.c 却是在编译时要指定盘子的数量。
比如5个盘子,用GNU编译器gcc编译的命令行是:(要区分大小写字母,大O和小o代表不同的意思)
gcc –ansi –O –Dn=5 vanschnitz_ioccc1995_Hanoi.c –o Hanoi2.x
产生的可执行文件是Hanoi2.x (当然你也可以使用其他名字,不指定可执行文件名字的话编译器用默认的名字a.out)
(3) Morse码加密解密。
编译运行dorssel_ioccc1998_morse.c
尝试解密下面的一行文字,回答文字所提出的问题,把答案再用Morse码加密后告诉老师。
.. .-.. --- ...- . -.-- --- ..-
(4)罗马数字表示法。
罗马数字有复杂的表示方法,比如把12345表示成mmmmmmmmmmmmcccxlv ,其中一个m代表一个一千(1000),一个c代表一个一百(100),字母l代表50,x代表10,v代表5,i代表一。
40 = 50 - 10 就要用 xl 表示。
字母x在l的左边代表比l(50)小x(10),即40。
编译运行wall_ioccc1987_roman.c并把你的学号的最后五位数组成的数值用罗马数字表示法来表示。
(5)自然对数的底e是一个无理数,有无穷多的小数位。
编译运行august_ioccc1986_e.c 计算e的数值到小数点后5000位以上,并把小数点后的第4990位至5000位记录下来。
(6)整数的阶乘。
编译运行savastio_ioccc1995_nfac.c并计算5!, 10!, 20!, 50!, 100!, 1000!, 5000!, 和 10000!。
当然,e的数值还可以用二进制、八进制、十六进制等表示。
编译运行程序jinrobison_ioccc1988_e.c并得出二进制、七进制、十六进制表示法中e的数值前20位。
(7)素数又称质数。
编译运行dalbec_ioccc1995_prim.c计算质数。
此程序还可以用不同的进制法计算质数。
(8)问计算机问题,看看它怎么回答。
先把一段英语文章保存在文件中(比如 文件),编译运行schnitzi_ioccc1993_askq.c,就文章内容提问计算机(某些示例问题在文件schnitzi_questions.txt中),看看它怎么回答。
运行时需要信息文件名作为命令行参数。
问题示例:What exactly does this program do?
(9)飞行的文字球体。
编译运行eldby_ioccc1995_flyball.c并观察运行结果。
(10)计算器。
hou_ioccc2011_calculator.c 模拟一个科学计算器,不仅可以四则运算,还可以使用函数。
编译运行进行体验。
robison_ioccc2013_mpmath.c可以进行多精度的整数四则运算。
当然,你需要使用一点小技巧就可以进行小数运算了。
比如你直接计算1/7会显示0,因为1比7小,除之后商的整数部分确实为0。
不过,你可以算100000000/7,再把小数点适当移动就得到1/7 = 0.14285714…是一个无限循环小数。
用类似的方法把13/79表示成循环小数的结果。
和你自己从商店购买的计算器计算结果比较,发现什么异同?。
