单选题Going Back to Its Birthplace No sporting event takes hold of the world's attention and imagination like the Olympic Games The football world Cup fascinates fans in Europe and South America; baseball's World Series is required viewing in North America; and the world table Tennis Championships attracts the most interest in Asia. But the Olympics belong to the whole world. Now, after travelling to 17 countries over 108 years, the summer Games are returning to Athens, the place where the first modern Olympics was held. Participation in the Games is looked on not only as an achievement, but also as an honour. The 16 days between August 13 and 29 will see a record that 202 countries compete up from Sydney's 199. Afghanistan is back, having been banned from Sydney because the Taliban government didn't let women do sports. There is also a place for newcomers East Timer and Kiribati. A total of 10,500 athletes will compete in 28 sports, watched by 53 million ticket paying viewers as well as a television audience of 4 billion. Athens is to use its rich history and culture to make the Olympics as special as possible. The Games will open with cycling events which start in front of the Parthenon and Acropolis monuments. The final event will be a historic men's marathon following the original route by Phidippides in 490 BC to bring news of victory over the Persians. The ancient stadium at Olympia first used for the Games nearly three centuries ago, will stage the shot put competitions. And the Panathenian Stadium, where the first modem Olympics was held, is to host the archery (射箭) events. If the well-known ancient sites deliver a great sense of history to the Games, the 39 new venues add a modem touch to the city of Athens. The main Olympic stadium, with a giant glass and steel roof, is the landmark (标志) building of the Olympics. "We believe that we will organize a 'magical' Games." said Athens 2004 President Gianna Angelopoulos-Daskalaki. "Our history with the Olympic Games goes back nearly 3,000 years, and Athens 2004 could be the best ever./

单选题 Internet-based Instruction By almost any measure, there is a boom in Internet-based instruction. In just a few years, 34 percent of American universities have begun offering some form of distance learning (DL), and among the larger schools, it's closer to 90 percent. If you doubt the popularity of the trend, you probably haven't heard of the University of Phoenix. It grants degrees entirely on the basis of online instruction. It enrolls 90,000 students, a statistic used to support its claim to be the largest private university in the country. While the kinds of instruction offered in these programs differ, DL usually signifies a course in which the instructors post syllabi (课程大纲), reading assignments, and schedules on Websites, and students send in their assignments by e-mail. Generally speaking, face-to-face communication with an instructor is minimized or eliminated altogether. The attraction for students might at first seem obvious. Primarily, there's the convenience promised by courses on the Net: you can do the work, as they say, in your pajamas (睡衣). But figures indicate that the reduced effort results in a reduced commitment to the course. While drop-out rates for all freshmen at American universities is around 20 percent, the rate for online students is 35 percent. Students themselves seem to understand the weaknesses inherent in the setup. In a survey conducted for Cornell, the DL division of Cornell University, less than a third of the respondents expected the quality of the online course to be as good as the classroom course. Clearly, from the schools' perspective, there's a lot of money to be saved. Although some of the more ambitious programs require new investments in servers and networks to support collaborative software, most DL courses can run on existing or minimally upgraded (升级) systems. The more students who enroll in a course but don't come to campus, the more the school saves on keeping the lights on in the classrooms, paying doorkeepers, and maintaining parking lots. And, while there's evidence that instructors must work harder to run a DL course for a variety of reasons, they won't be paid any more, and might well be paid less.

单选题Costa Rica is insisting that economic growth and environmentalism work together. It has created a holistic(整体的，全面的)strategy to think about growth, one that demands that everything gets counted. So if a chemical factory sells tons of fertilizer but pollutes a river - or a farm sells bananas but destroys a carbon - absorbing and species - preserving forest - this is not honest growth. You have to pay for using nature. It is called "payment for environmental services"—nobody gets to treat climate, water, fish and forests as free anymore. The process began in the 1990s when Costa Rica, which sits at the intersection of two continents and two oceans, came to fully appreciate its incredible gift of biodiversity - and that its economic future lay in protecting it. So it did something no country has ever done: It put energy, environment, mines and water all under one minister. Costa Rica started to protect the environmentA. when it came to realize the importance of biodiversity in the 1990s.B. after its environment had been severely destroyed in the 1990s.C. before it had created a holistic strategy to think about growth.D. when the economy started to grow fast at the expense of environment.

单选题{{B}}第三篇{{/B}} Ellen MacArthur started sailing when she was eight，going out on sailing trips with her aunt．She loved it so much that she saved her money for three years to buy her first small sailing boat．When she was 18，she sailed alone around Britain and won the“Young Sailor of the Year”award． But Ellen really became famous in 2001．Aged only 24，she was one of only two women who entered the Vendee Globe round the world solo race，which lasts t00 days．Despite many problems，she came second in the race out of 24 competitors and she was given a very warm welcome when she returned． Ambition and determination have always been a big part of Ellen's personality．When she was younger，she lived in a kind of hut(棚屋) for three years while she was trying to get sponsorship to compete in a transatlantic race．Then she took a one-way ticket to France，bought a tiny seven meter Class Miniyacht，slept under it while she was repairing it，and then she raced it 4，000 kilometers across the Atlanticin 1997，alone for 33 days． Ellen has had to learn many things，because sailing single-handed means that she has to be her own captain，electrician，sailmaker，engineer，doctor，journalist，cameraman and cook．She also has to be very fit，and because of the dangers of sleeping for long periods of time she's in the middle of the ocean，she has trained herself to sleep for about 20 minutes at a time． And she needs courage．Once，in the middle of the ocean，she had to climb the mast(桅杆) of a boat to repair the sails-at four o'clock in the morning，with 100kph winds blowing around her．It took her many hours to make the repairs；Ellen says：“I was exhausted when I came down．It's hard to describe how it feels to be up there．It's like trying to hold onto a big pole，which for me is just too big to get my arms around，with someone kicking you all the time and trying to shake you off”． But in her diary，Ellen also describes moments which make it all worthwhile(值得的)：“A beautiful sunrise started the day，with black clouds slowly lit by the bright yellow sun．I have a very strong feeling of pleasure，being out here on the ocean and having the chance to live this．I just feel lucky to be here”．
