Q: Article: The Olympic Games are seen as the greatest test of an athlete's ability and are supposed to celebrate the spirit of fair play. But in fact, sportsmen have been using drugs to cheat their way to victory since the Games first began. In the early years, athletes ate mushrooms and plant seeds to improve their performance. Nowadays, this kind of cheating has a name doping . Just last month, Britain's top sprinter Dwain Chambers and several American athletes tested positive for the drug THG. Until a coach secretly gave a sample of THG to scientists, no one knew how ho test for it. "We're like cops chasing criminals--athletes are always adapting and looking for areas we haven't investigated," said Jacquew de Ceaurriz, a French anti-doping expert. Since the first drugs test was carried out at the 1968 Olympics in Mexico City, many cheats have been caught out. The most famous case in history is that of Canadian sprinter Ben Johnson. He broke the 100 meters world record in winning gold at the 1988 Seoul Olympics. But days later, he tested positive for drug use, lost his gold medal and was banned from the sport. Five years later, he returned to action--only to be found positive again and banned forever. China has also had problems with drug cheats. At the 1994 Asian Games, 11 Chinese athletes--seven of them swimmers--tested positive for banned drugs. Sports organizations promised that cheating on this scale would not happen again. Experts are also worried that doping can damage a person's health. It is believed to increase the risk of liver and kidney diseases, and women may experience reproductive problems. As long as they can stay ahead of the scientists, it is unlikely the cheats will stop. But experts say there is a limit to what can be achieved and that athletes will not be able to change their bodies using gene technology. "For the moment, genetic doping does not exist," said de Ceaurriz. "Even in 10 or 15 years it will not be done easily--the scientific community will not let it happen." Question: We can infer from the passage that _ . Yes or no, is the answer "problems with drug cheats are still serious though they are severely tested"?
A: No

Q: Article: "I sometimes get up at three or four in the morning and I surf the net." "I often check my e-mail forty times a day. " "I often spend more than three hours during one time on the net." "I spend more time in chat rooms than with my 'real-life' friends." Do you know any people like these? They are part of a new addiction called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug use. People lose control of the time they spend on the Internet. For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight. Studies show that about 6% to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them. They spend more time in cyberspace than in the real world of friends and family. Is "surfing the net" a hobby or an addiction for you? You may have a problem if you have these symptoms : 1You do not go to important family activities or you do not do school work because you like to spend hours on the Internet. 2You can't wait for your next online time. 3You go out with your friends less and less. 4You plan to spend a short time online, but then you spend several hours. Question: What is the writer trying to tell us at the end of the passage? Yes or no, is the answer "Don't be addicted to the Internet."?
A: No

Q: Article: Some Chinese new-rich like eating shark fin soup because they think it shows their class. However, for the Chinese NBA idol Yao Ming, doing so is unacceptable as the practice has led to the overfishing of sharks. When Yao and his wife Ye Li got married in 2007, they publicly announced that they would not allow shark fin soup to be served at their wedding banquet. Actually, Yao had been saying no to shark fins since 2006, when he was appointed as the Goodwill Ambassador for wild life protection. Now, the 226-cm big guy is resorting to his personal influence to encourage more to say no to eating the soup and to raise awareness of animal protection. "Sharks are friends of human beings. They are not our food," Yao said. Other celebrity athletes like Olympic champions Li Ning and Kong Linghui are following on the heels of Yao, throwing themselves into serving the public as Goodwill Ambassadors for wild animal rescue. Recent reports about Yao's retirement have saddened tens of thousands of basketball fans both at home and abroad. Yet Yao's influence goes far beyond the basketball courts. Yao has engaged himself in charity and public welfare services for quite a while. When the devastating 8.0-magnitude earthquake hit Wenchuan in southwest China in 2008, Yao donated 2 million yuan . "When I was a little boy, my parents and teachers told me to help others and to be a good man," Yao recalled. "But I could not donate then because I had not much pocket money. After I moved to Houston, I got involved in quite a number of community service activities and I felt a strong sense of achievement when I got people together," Yao said. Like Yao, newly crowned French Open champion Li Na has showed her willingness to donate. Li gave 480,000 yuan of her prize money from the open, plus 20,000 yuan from her own pocket, to a local nursing home in her hometown. Another Chinese sports icon, hurdler Liu Xiang, has also been actively involved in charity for years. Question: The reason why some Chinese new-rich like eating shark fin soup is that they think _ . Yes or no, is the answer "it can show their status"?
A: Yes

Q: Article: High-quality customer service is attached great importance to by many, but actually keeping customers happy is easier said than done. Shoppers seldom complain to the manager or owner of a retail store , but instead will alert their friends, s, co-workers and even strangers. Store managers are often the last to hear complaints, and often find out only when their regular customers frequently go to their competitors, according to a study jointly conducted by Verde Group and Wharton School. "Storytelling hurts retailers and affects customers," said Paula Courtney, President of the Verde Group. "The store loses the customer, but the shopper must also find a replacement." On average, every unhappy customer will complain to at least four others, and will no longer visit the specific store. For every dissatisfied customer, a store will lose up to three more due to negative review. The resulting "snowball effect" can be disastrous to retailers. According to the research, shoppers who bought clothing met with the most problems. Ranked second and third were grocery and electronics customers. The most common complaints include filled parking lots, cluttered shelves, overloaded racks, out-of-stock items, long check-out lines, and rude salespeople. During peak shopping hours, some retailers solved parking problems by getting moonlighting local police to work as parking attendants. Some hired flag wavers to direct customers to empty parking spaces. This guidance completely got rid of the need for customers to circle the parking lot endlessly, and avoided the situation in which several customers eyed the same parking space at the same time. Retailers can relieve the headaches by redesigning store layouts, pre-stocking sales items, hiring speedy and experienced cashiers, and having sales representatives on hand to answer questions. Most importantly, salespeople should be good at dealing with different people and especially should be...
