案例分析题A Pay Rise or Not"Unless I get a rise, I’ll have a talk with the boss, Henry Manley," George Strong said to himself. George liked his job and he liked the town he lived in, but his wife kept telling him that his pay was not enough to meet the needs of the family. That was why he was thinking of taking a job in Birmingham, a nearby city about 50 miles away. He had been offered a job in a factory there, and the pay was far better.George lived in Wyeford, a medium-sized town. He really liked the place and didn’t like the idea of moving somewhere else, but if he took the job in Birmingham, he would have to move his family there.Henry manley was the manager of a small company manufacturing electric motors. The company was in deep trouble because, among other reasons, the Japanese were selling such things at very low prices. As a result, Manley had to cut his own prices and profits as well. Otherwise he would not get any orders at all. Even then, orders were still not coming in fast enough, so that there was no money for raises(加工资)for his workers. Somehow, he had to struggle along and keep his best workers as well. He sighed. Just then the phone rang.His secretary told him that George Strong wanted to see him as soon as possible. Manley sighed again. He could guess what it was about. George Strong was a very young engineer. The company had no future unless it could attract and keep men like him. Manley rubbed his forehead（前额）; his problems seemed endless. Henry Manley’s company was making enough profits to raise the workers’wages.（）

说明：计算中使用1G≈109；1M≈106；1K≈103。网络时延带宽积可以由带宽和往返时延相乘得到。考虑两个网络：一个是无线网络，带宽为54Mbps，RTT为0.3μs；另一个是远距离的光纤网络，带宽为10Gbps，RTT为40ms。①分别计算两个网络的时延带宽积；②说明该乘积值对于分析网络性能的意义；③若传输一个1MB的文件，试比较两个网络的有效利用率。
案例分析题Up in SmokeI began to smoke when I was in high school. In fact, I remember the evening I was at a girlfriend’s house, and we were watching a movie-a terribly romantic movie. He (the hero of the movie) was in love, she (his lady) was beautiful, and they were both smoking. My friend had only two cigarettes from a pack in her mother’s purse, and she gave one to me. It was my first time.My parents didn’t care much. They both smoked, and my older brother did too. My mother told me that smokers don’t grow tall, but I was already5’6"(taller than most of the boys in my class), so I was happy to hear that "fact". In school, the teachers talked against smoking, but the cigarette advertisements were so exciting. The men in the ads were so good-looking and so successful, and the women were-well, they were beautiful and sophisticated(老于世故的).I read a book called how to stop smoking. The writer said that smoking wastes time, and that cigarettes cost a lot of money. "So what" I thought, the book didn’t say that smoking can take away years of your life. But ten years later, everyone began to hear about the negative effects of cigarette smoke: lung disease, cancer, and heart problems. After that, there was a health warning on every pack of cigarettes. I didn’t pay much attention to the reports and warnings. I felt healthy, and I thought I was taking good care of myself.Then two events changed my mind. First, I started to cough. I thought it was just a cold, but it didn’t get better. Second, my brother got lung cancer. He got sicker and sicker. My brother and I used to smoke cigarettes together over twenty years age, and we smoked our last cigarettes together the day before he died. I sat with him in his hospital room, and I decided to quit. "NO more cigarettes, ever," I said to myself.However, it was very hard to stop, Nicotine(尼古丁)is a drug; as a result, cigarettes cause a powerful addiction. I tried several times to quit on my own-without success. I made excuses. I told myself: Smoking helps me keep my figure-i.e. I don’t gain weight when I smoke. Smoking not only relaxes me but it also helps me think clearly. I’m a free, liberated woman. I can smoke when I want to.Finally, I ran out of excuses-I might say my excuses went up in smoke. I joined the "Stop Smoking" program at the local hospital, which also ended up in failure. The writer decided to quit smoking partly because（）

案例分析题what Makes a Soccer Player GreatSoccer is played by millions of people all over the world, but there have only been few players who were truly great. How did these players get that way-was it through training and practice, or are great players’ born, not made" First, these players came from places that have had famous stars in the past---players that a young boy can look up to and try to imitate（效仿）.In the history of soccer, only six countries have ever won the World Cup-three from South America and three from Western Europe. There has never been a great national team-or a really great player-from North America or from Asia. Second, these players have all had years of practice in the game. Alfredo Di Stefano was the son of a soccer player, as was Pele. Most players begin playing the game at game at the age of three or four.Finally, many great players come from the same kind of neighbourhood(聚居区)-a poor, crowded area where a boy’s dream is not to be a doctor, lawyer, or businessman, but to become a rich, famous athlete or entertainer. For example, Liverpool which produced the Beatles(甲壳虫乐队)，had one of the best English soccer teams in recent years. Pele practiced in the street with a "ball" made of rags(破布). And George Best learned the tricks that made him famous by bouncing the ball off a wall in the slums(贫民窟)of Belfast.All great players have a lot in common, but that doesn’t explain why they are great. Hundreds of boys played in those Brazilian streets, but only one became Pele. The greatest players are born with some unique quality that sets them apart from all the others. The word "tricks" at the end of Paragraph 2 is closest in meaning to（）
