单选题Tom Brennan was working in a Philadelphia office building when he noticed a black bag. The bag contained a book. This chance discovery ended a 12-day search by the Library Company of Philadelphia for a historical treasure, a 120-page diary kept 190 years ago by Deborah Logan, "a woman who knew everybody in her day," James Green, the librarian told the magazine American Libraries. Most of the diary is a record of big events in Philadelphia. It also includes a description of British soldiers burning Washington, D. C. in the war of 1812. She describes President James Madison on horseback as "perfectly shaking with fear" during the troubled days. George Washington, she writes, mistook her for the wife of a Freneh man, and praised her excellent English. The adventure of the lost book began September 4 when Cory Luxmoore arrived from England to deliver the diary of his ancestor (祖先) to the Library Company, which he and his wife considered to be the best home for the diary. Green told American Libraries he had the diary in his possession "about five minutes" when Luxmoore took it back because he had promised to show it to one other person. On returning to his hotel after showing the precious book to Green, Luxmoore was shocked to realize that he had left it in the taxi. Without any delay, Green began calling every taxi company in the city, with no luck. "I've felt sick since then," Luxmoore told reporters. According to Green, no one has yet learned how the diary came to the office building. Tom Brennan received a reward (奖励) of ＄1,000, Philadelphia gained another treasure for its history, and Luxmoore told reporters, "It's wonderful news. I'm on high./

单选题She once said," When people ask me whether writing has been a hard or easy road I always answer with the famous saying: The end is nothing; the road is all. That is what I mean when I say writing has been a pleasure. I have never faced the type-writer with the thought that one more task had to be done." Like most writers, Willa Cather did not write books for the money that they brought her. but rather for the pleasure that came in their writing. Her works were, like her, simple and full of the vigor of her days in Nebraska, where she grew from childhood to young womanhood and where she developed a deep love for the treeless land of the great plains with its wild flowers, wheat fields and rivers. "It's a rather strange thing about the flat country," she wrote later. "It takes hold of you, or it leaves you perfectly cold. 'A great many people find it very dull: they like a church tower, an old factory, a waterfall, the country all made to look like a German Christmas card... But when I come to the open plains, something happens. I'm home. I breathe differently./

单选题According to statistics, in 2007 more than 6,000 children were expulsed (开除) from US schools for bringing guns and bombs to school. The US Department of Education gave a report to the expulsions as saying handguns accounted for 58 percent of the 6,093 expulsions in 2003-2004, against 7 percent for rifles(步枪) or shotguns and 35 percent for other types of firearms. "The report is a clear sign that our nation"s public schools are cracking down (严惩) on students who bring guns to school," Education Secretary Richard Riley said in a statement. "We need to be strong-minded about keeping guns out of our schools and do everything to keep our children safe." In March 2004, an 11 years old boy and 13 years old boy using handguns and rifles shot dead four children and a teacher at a school in Jonesboro, Arkansas. In October, two were killed and seven were wounded in a shooting at a Mississippi school. Two months later, a 14 years old boy killed three high school students and wounded five in Dasucah, Kentucky. Most of the expulsions, 56 percent, were from high schools, which have students from about age 13.34 percent were from junior high schools and 9 percent were from elementary schools, the report said.

单选题A characteristic of American culture that has become almost a tradition is to respect the self-made man—the man who has risen to the top through his own efforts, usually beginning by working with his hands. While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort. This attitude toward manual (体力的)labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriousl(豪华地)furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery. On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional man may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.
