单选题Washington Irving was America"s first man of letters to be known internationally. His works were received enthusiastically both in England and in the United States. He was, in fact, one of the most successful writers of his time in the country, and at the same time winning the admiration of fellow writers like Scott in Britain and Poe and Hawthorne in the United States. The respect in which he was held partly owing to the man himself, with his warm friendliness, his good sense, his urbanity, his gay spirits, his artistic integrity, his love of both the Old World and the New. Thackeray described Irving as "a gentleman, who, though himself born in no very high sphere, was most finished, polished, witty ; socially the equal of the most refined Europeans." In England he was granted an honorary degree from Oxford—an unusual honor for a citizen of a young, uncultured nation—and he received the medal of the Royal Society of Literature. America made him ambassador to Spain. Irving"s background provides little to explain his literary achievements. A gifted but delicate child, he had little schooling. He studied law, but without zeal, and never did practice seriously. He was immune to his strict Presbyterian home environment, frequenting both social gatherings and the theater.

单选题A recent study, published in last week"s Journal of the American Medical Association, offers a picture of how risky it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a fatal accident as a teenager driving alone. By contrast, the risk of death for drivers between 30 and 59 decreases with each additional passenger. The author also found that the death rates for teenage drivers increased dramatically after 10 p. m., and especially after midnight, with passengers in the car, the driver was even more likely to die in a late-night accident. Robert Foss, a scientist at the University of North Carolina Highway Safely Research Center, says the higher death rates for teenage drivers have less to do with "really stupid behavior" than with just a lack of driving experience. "The basic issue", he says, "is that adults who are responsible for issuing licenses fail to recognize how complex and skilled a task driving is." Both he and the author of the study believe that the way to mitigate (是缓解) the problem is to have states institute so-called graduated licensing systems, in which getting a license is a multistage process. A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult, followed by a period of driving with night of passenger restrictions, before graduating to full driving privileges. Graduated licensing systems have reduced teenage driver crashes, according to recent studies. About half of the states now have some sort of graduated licensing system in place, but only 10 of those slates have restrictions on passengers. California is the strictest, with a novice (新手) driver prohibited from carrying any passenger under 20 (without the presence of an adult over 25 ) for the first six months.
