单选题More than 30,000 drivers and front seat passengers are killed or seriously injured each year. At a speed of only 30 miles per hour it is the same as falling from a third-floor window. Wear a seat belt saves lives; it reduces your chance of death or serious injury by more than half. Therefore drivers or front passengers over 14 in most vehicles must wear a seat belt. If you do not, you could be fined up to $50. It will not be up to the drivers to make sure you wear your belt. But it will be the driver"s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind. However, you do not have to wear a seat belt if you are reversing(倒开) your vehicle; or you are making a local delivery or collection using a special vehicle; or if you have valid (有效的) medical certificate which excuses you from wearing it. Make sure these circumstances apply to you before you decide not to wear your seat belt. Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court that you have been excused from wearing it.

单选题Over the last decade, Dr. Benjamin Van Voorhees has been trying to find the best way to teach coping strategies to adolescents who are at risk of suffering from severe depression. The idea is to help them keep depression at bay so that it doesn"t become a devastating part of their lives. The goal is to identify kids at risk and then use a combination of traditional counseling and Internet-based learning to keep off mental disorders and their accompanying medicines. Van Voorhees said he wants to change the way doctors, especially pediatricians, deal with mental illness by moving the focus, which is now so heavily trained on treatment, to prevention. He said, "We"re trying to develop a type of behavioral vaccine that functions the same way vaccines work in fighting infections. We hope this approach will be simple, culturally acceptable, universally deployable—and inexpensive." He said that initial depressive episodes tend to strike between the ages of 13 and 17. Once an adolescent develops into severe depression, episodes can recur across his or her lifetime. Van Voorhees said young people establish patterns of coping in adolescence and young adulthood. "There"s a period of plasticity in the brain during which it"s developing the capacity for learning new coping skills," he said. "You want to make youths elastic against mental disorders, and you try to give them ways to cope so that they don"t fall into substance abuse." His research has been testing the effectiveness of Internet use and other techniques to hone such skills. Project CATCH-IT is a multimillion-dollar study. CATCH-IT includes an initial motivational interview with a physician to get the young person to understand the importance of the program. It also has a self-contained learning component on the Internet that focuses on changing behavior and improving cognitive thinking and social skills. The website, which has evolved over time, teaches plasticity skills in part by allowing patients to read stories about other teens to learn how they overcame adversity and became more successful in school, their relationships or on the job. Van Voorhees said the goal is to reach as many young people as possible. They want to develop a model that will be embedded in primary care with pediatricians screening kids who are at risk for mental disorders and trying to prevent them ahead of time. Over the years CATCH-IT has shown some evidence of being effective. But in February a new study, called PATH, was begun to determine whether CATCH-IT does a better job of preventing depression than routine mental health care and health education that teens can find online. "With CATCH-IT alone, we saw depression dropping over the years, but we didn"t have anything to compare it to," said Monika Marko-Holguin, PATH"s project manager.

单选题LAST month, America's National Law Journal told its readers that "employment lawyers are warning lovestruck co-workers to take precautions in the office before locking lips outside". The advice came too late for Harry Stonecipher. The boss of Boeing was forced to resign last weekend—for reasons that will strike many outsiders as absurd—after his board were told of an affair that the 68-year-old married man had been conducting with a female employee "who did not report directly to him". Inevitably, as the week rolled on, details of the affair rolled out. The other party was reported to be Debra Peabody, who is unmarried and has worked for Boeing for 25 years. The couple were said to have first got together at Boeing's annual retreat at Palm Desert, California in January. After that much of the affair must have been conducted from a distance: Mr. Stonecipher's office is at Boeing's headquarters in Chicago; Ms Peabody runs the firm's government-relations office in Washington, DC. They exchanged e-mails, it seems, as office lovers tend to do these days, and therein probably lay Mr Stonecipher's downfall. Lewis Platt, Boeing's chairman, said that Mr Stonecipher broke a company rule that says: "Employees will not engage in conduct or activity that may raise questions as to the company's honesty, impartiality, reputation or otherwise cause embarrassment to the company." Having an affair with a fellow employee is not, of itself, against company rules; causing embarrassment to Boeing is. It seems that the board judged that the contents of the lovers' e-mails would have been bad for Boeing had they been made public. Gone are the days when a board considered such matters none of its business, as Citibank's did in 1991 when its boss, John Reed, became the talk of Wall Street for having an affair with a stewardess on Citi's corporate jet. At Boeing, a whistleblower is said to have forwarded the messages to Mr Platt. In general, e-mails are encrypted and not accessible to anyone who does not know the sender's password. But many firms install software designed to search electronic communications for key words such as, "sex" and "CEO". A study last year of 840 American firms by the American Management Association found that 60% of them check external e-mails (incoming and outgoing), while 27% scrutinize internal messages between employees. Sweet nothings whispered by the water cooler may travel less far these days than electronic billets doux. Boeing is particularly sensitive to embarrassment at the moment. Mr. Stonecipher was recalled from retirement only 15 months ago, after the company's previous boss, Phil Condit, and its chief financial officer, Michael Sears, had left in the wake of a scandal involving an illegal job offer to a Pentagon official. Mr Stonecipher, a crusty former number two at Boeing, was brought back specifically to raise the company's ethical standards and to help it be seen in its main (and affectedly puritanical) market, in Washington, DC, as squeaky clean. Verbally explicit extra-marital affairs are inconsistent with such a strategy, it seems, though they are not yet enough to bring down future kings of England. In corporate life, such affairs are hardly unusual. One survey found that one-quarter of all long-term relationships start at work; another found that over 40% of executives say they have been involved in an affair with a colleague, and that in half of these cases one or other party was married at the time. Many a boss has married his assistant and lived happily ever after. Boeing apparently used to accept this: Mr. Condit's fourth wife was a colleague before they married.

单选题{{B}}Text 4{{/B}} You cannot buy Prada shoes on Prada. com. In fact, there are no working links on the Web site. This is not a technical disorder. Since the late' 9Os, the site has been a single page, with only the name of the Italian fashion house and two photographs. No store locations or help numbers. Nothing. "I love Prada," ponders Nina Dietzel, president of Web-design company 300FeetOut. "But what's up with their 'site' ?" Prada claims a new Web site is "under development." But having a mysteriously useless home page, it admits, has an allure. It screams exclusivity: you can see, but you can't click. It's a uniquely Prada solution to this riddle: how to make your luxury brand work on the Internet without diminishing its value. In a sense, the Internet is antithetical to the "high touch" luxury experience. There is no indulgence by sales staff, and customers have come to see the Net as a path to cheap prices, not top-dollar goods. There's no velvet rope: anyone can place an order, or set up shop. That's why Prada strives to maintain the link between its name and the extravagant experience of shopping at stores like its $ 40 million New York flagship, designed by Rem Koolhaas. Unlike Prada, most luxury companies can't afford to ignore the Web: in the United States, ecommerce accounted for $ 2.5 billion in luxury sales. That figure is expected to grow to $ 7 billion by 2010, says Forrester Research. It's still a small fraction of the total market compared to other retail sectors, but five years ago analysts said there was "no way" luxury would sell online. They were betting customers wouldn't pay that much on the Web, and top brands wouldn't go slumming in this bargain basement. One of the first high-end luxury retailers, Ashford. com, had many well-publicized struggles, with its stock dropping to near rock bottom in 2001. Companies like Neiman Marcus that have strong catalog sales have made the transition to the Web more easily; online sales are the company's fastest-growing source of revenue. Swiss watchmakers Breitling and Patek Philippe have taken another tack with Web sites that offer only information, not sales. Breitling director of marketing Ben Balmer says a luxury brand needs to offer "a buying experience" that only a well-run store can provide. However, he notes that since 2002, it has presented 30 percent fewer catalogs in the United States, and seen sales rise more than 35 percent, thanks to exposure on the Internet. Prada may not need a working Web site after all.

单选题A proven method for effective textbook reading is the SQ3R method developed by Francis Robinson. The first step is to survey (the S step) the chapter by reading the title, introduction, section headings, summary and by studying any graphs, tables, illustrations or charts. The purpose of this step is to get an overview of the chapter so that you will know before you read what it will be about. In the second step (the Q step), for each section you ask yourself questions such as "What do I already know about this topic?" and "What do I want to know?" In this step you also take the section heading and turn it into a question. This step gives you a purpose for reading the section. The third step (the first of the 3 R's) is to read to find the answer to your questions. Then at the end of each section, before going on to the next section, you recite (the second of the 3 R's) the answers to the questions that you formed in the question step. When you recite you should say the information you want to learn out loud in your own words. The fifth step is done after you have completed steps 2, 3 and 4 for each section. You review (the last of the 3 R's) the entire chapter. The review is done much as the survey was in the first step. As you review, hold a mental conversation with yourself as you recite the information you selected as important to learn. The mental conversation could take the form of asking and answering the questions fromed from the headings or reading the summary, which lists the main ideas in the chapter, and trying to fill in the details for each main idea.
