单选题The legal limit for driving after drinking alcohol is 80 milligrams of alcohol in 100 milliliters of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, whether you have just eaten and what sort of drinks you have had. Some people might reach their limit after only about three standard drinks. In fact, your driving ability can be affected by just one or two drinks. Even if you are below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol. It takes about an hour for the body to get rid of the alcohol in one standard drink. Or, if you have a heavy drinking in the evening you might find that your driving ability is still affected the next morning, or you could even find that you are still over the legal limit. In addition, if you have had a few drinks at lunchtime, another one or two drinks in the early evening may well put you over the legal limit. In a test with professional drivers, the more alcoholic drinks they had had the more certain they were that they could drive a test course through a set of moveable posts and the less able they were to do it! So the only way to be sure you are safe is not drink at all. Alcohol is a major cause of road traffic accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, and road accidents after drinking are the biggest cause of death among young men. More than half of the people stopped by the police to take a breathalyzer (呼吸分析器) test have a blood alcohol concentration of more than twice the legal limit. It is important to remember that driving after you have been drinking does not just affect you. If you are involved in an accident it affects a lot of other people as well, not least the person you might kill or injure.

单选题 An 84-year-old widow recently emerged from her small, tin-roofed house in Florida to collect the biggest undivided lottery jackpot in history. The blogosphere is full of advice for this lucky Powerball pensioner. But if she hopes her new-found lucre will yield lasting feeling of fulfillment, she could do worse than read Happy Money by Elizabeth Dunn and Michael Norton. These two academics use an array of behavioral research to show that the most rewarding ways to spend money can be counterintuitive. Fantasies of great wealth often involve visions of fancy cars and palatial homes on remote cliffs. Yet satisfaction with these material purchases wears off fairy quickly. What was once exciting and new becomes old-hat; remorse creeps in. It is far better to spend money on experiences, say Ms. Dunn and Mr Norton, like interesting trips, unique meals or even going to the cinema. These purchases often become more valuable with time—as stories or memories—particularly if they involve feeling more connected to others. This slim volume is packed with tips to help wage slaves as well as lottery winners get the most happiness bang for your buck. It seems most people would be better off if they could shorten their commuters to work, spend more time with friends and family and less of watching television. Buying gifts or giving to charity is often more pleasurable than purchasing things for oneself, and luxuries are most enjoyable when they are consumed sparingly. This is apparently the reason McDonald's restricts the availability of its popular McRib—a marketing trick that has turned the pork sandwich into an object of obsession. Readers of Happy Money are clearly a privileged lot, anxious about fulfillment, not hunger. Money may not quite buy happiness, but people in wealthier countries are generally happier than those in poor ones. Yet the link between feeling good and spending money on others can be seen among rich and poor people around the world, and scarcity enhances the pleasure of most things for most people. Not everyone will agree with the authors' policy ideas, which range from mandating more holiday time to reducing tax incentives for American homebuyers. But most people will come away from this book believing it was money well spent.

单选题Passage Three Burn rate is the speed at which a startup business consumes money. My rate would be $50,000 a month when my new media company started. So, I began looking around for individuals who would be my first investors. "Angel money" it was called. But when I reviewed my list of acquaintances, I found the number got small. With no other choices, I began meeting with the venture-capital companies. But I was warned they took a huge share of your company for the money they put in. And if you struggled, they could drop you cold. As I was searching for "angel money", I started to build a team who trusted me even though I didn't have money for paychecks yet. Bill Becker was an expert in computer programming and image processing at a Media Lab at M.I.T. With his arrival, my company suddenly had a major technology "guy" in-house. Katherine Henderson, a fihnmaker and a former real-estate dealer, joined us as our director of market research. Steve White came on as operating officer. We had some really good people, but we still didn't have enough money. One night, my neighbor, Louise Johnson, came for a visit. She and I were only nodding acquaintances, but her boys and ours were constant companions. She ran a very good business at the time. Louise was brilliant and missed nothing. She had been watching my progress closely. She knew I was dying for money and I had prospects but could offer no garantees of success. She told me that her attorney had talked to mine and the terms bad been agreed upon. She handed me an envelope with a check for $ 500,000. I almost fell down. I heard her voice as if from heaven. "I have confidence in your plan," she said. "You'll do well. You're going to work hard for it, but it's satisfying when you build your own company." Who would have thought l'd find an angel so close to home. There were no words sufficient for the moment. We just said good night. She left and I just stood there, completely humbled and completely committed.

单选题"History is so immediate here," said Marie Martin, incoming president of the St. Michaels Museum's board of directors. "Let's face it—St. Michaels is a museum. Everybody here is a volunteer." The museum comprises three buildings, each of which has its own history. The Teetotum is a small building that began life as a commercial structure about the time of the Civil War, and served at one time or another as a judge's office, a town jail, a saddle shop, a mortuary (太平间), a bank and a barber shop. It is filled with bits of St. Michaels' commercial history, ranging from carpentry tools to an intricately decorated shoeshine stand and including a body board for carrying a corpse (尸体). "At one time, there were five funeral homes in St. Michaels," Kate Fones, who is in charge of the Museum, pointed out. Teetotum is connected to the Sewell House, the first building of the museum, which was moved to the museum site in 1964. The building focuses on the home life during the 19th century, including period furniture and home artifacts of a local nature, ranging from an intricate apple peeler and heavy clothes irons that had to be heated over a fire to a chamber pot (夜壶). The Sewell House also has its own history, being half of a building that was cut in two to provide two homes. The Sewell family added a kitchen and a loft to the two-story half home. "The whole thrust of the museum is to protect and preserve the history, understand what was here," Martin said. The museum also tries to fell the 19th century history of African Americans in the town. The most recently added of the three buildings that make up the museum is the Chaney House, a two-story, two-room house that was owned by three free African Americans after it was built around 1850. The museum staff tries to appeal to year-round residents as well as summer people and other tourists. Having a steady supply of new exhibits, two per year, is a way to do that.
