单选题Passage1Soon after starting his job as superintendent of the Memphis,Tenn.,public schools,Kriner Cash ordered an assessment of his new district's 104,000 students. The findings were depressing:nearly a third had been held back at least one academic year. The high school graduation rate had fallen to 67%.One in five dropped out. But what most concerned him was that the number of students considered highly mobile,meaning they had moved at least once during the school year,had ballooned to 34,000,partly because of the home-foreclosure crisis. At least 1,500 students were homeless-probably more.I had a whole array of students who were angry,depressed,not getting the rest they needed,Cash says. It led him to consider an unusual proposition: What if the best way to help kids in impoverished urban neighborhoods is to get them out?Cash is now calling for Memphis to create a residential school for 300 to 400 kids whose parents are in financial distress,with a live-in faculty rivaling those of elite New England prep schools. If Cash's dream becomes a reality,it will probably look a lot like SEED,a charter school in Southeast Washington,which stands for Schools for Educational Evolution and Development. Its 320 students-seventh-to 12th-graders-should live on campus five days a week. They are expected to adhere to a strict dress code and keep their room tidy. There are computers in the dorm's common areas, and each student in grades 10 and above is given a desktop computer. At 11:30 every night it's lights out.In his plan for Memphis, Cash wants even more time. Perhaps the most provocative aspect of his proposal is to focus on students in grades 3 through 5 for homelessness is growing sharply among kids at that critical age, when much of their educational foundation is set, Cash says. His aim: to prevent illiteracy and clear other learning roadblocks early, so the problem won't migrate into middle and high school. Students will remain on campus year-round. The school would cost up to S50,000 a day to operate-three times the cost of a traditional day school with more than twice as many students.It sounds very exciting, but the devil is in the details. says Ellen Bassuk, president of the National Center on Family Homelessness in Newton, Mass.Why does Cash want to concentrate on students from the third to the fifth grade?AMore children at that critical age become homeless.BChildren at that age have more problems.CThat age is very important for learning.DIt is the best time to build educational foundation.

单选题Passage2The way people work has changed. The increasing use of technology presents new and continual challenges to small and large businesses,employees and managers,teachers and students.Everyone,it seems,is being affected by the technological revolution. Store clerks,for example,now use increasingly complex computerized cash registers,while university professors must learn to adapt their teaching skills in order to lead distance learning course.In today's world,training and learning do not stop when we finish school;they must now continue throughout our working lives. The Hong Kong government conducted a survey on the employment concerns,and training needs of its workforce. For many managers and other professionals the biggest challenge,as well as change,in the workplace,was the increased use of computers and computerized machinery or equipment. The need for experienced employees who could use this kind of equipment rose drastically. Many of those in the workplace at this time experienced changes in job requirements and had to attend job-related training or re-training courses.The changing work environment is also affecting education and how we learn. In Finland, a report on strategies for education and training in the information age discussed the changing roles of both teacher and student. With the increased use of technology and the growth of distance learning, the teacher has become more of a tutor who guides a student, rather than a lecturer. In turn, the student has to take more responsibility for his or her learning in the absence of direct teacher contact. The report also stressed that high school and university students should learn computer skills in order to cope with the demands of the future workplace.The Finnish report also highlighted the need for teacher training, and re-training, and suggested that the salaries and job descriptions of teachers be reviewed because of future demands expected in their jobs. Previously university professors may have held lectures between the weekday hours of 9:00A.M. and 5:00 P.M. in large halls filled with students. Now, they may spend part of their day lecturing larger groups of students on campus, and then conduct afternoon or evening classes online, with students in five different countries.As technologies grow and develop, ongoing training will continue to be necessary. To be successful in the workplace, people will not stop learning when they leave school-lifelong learning will become a way of life.From the first paragraph of the passage we know that_______.Aeveryone has to learn how to use complex computersBtechnological revolution has brought changes to people's workCthe use of new technology has got small business into large onesDeven university professors have to learn the new technology in distance courses

单选题Passage 2The subject of ballads, books and films, Robin Hood has proven to be one of popular culture's most enduring folk heroes. Over the course of 700 years, the outlaw from Nottinghamshire who robs the rich to give to the poor has emerged as one of the most enduring folk heroes in popular culture--and one of the most versatile. But how has the legend of Sherwood Forest's merry outlaws evolved over time? Did a real Robin Hood inspire these classic tales?Beginning in the 15th century and perhaps even earlier, Christian revelers in certain parts of England celebrated May Day with plays and games involving a Robin Hood figure with near-religious significance. In the 19th century, writer-illustrators like Howard Pyle adapted the traditional tales for children, popularizing them in the United States and around the world. More recently, bringing Robin to the silver screen has become a rite of passage for directors ranging from Michael Curtiz and Ridley Scott to Terry Gilliam and Mel Brooks.Throughout Robin's existence, writers, performers and filmmakers have probed their imaginations for new incarnations that resonate with their respective audiences. In 14th-century England, where agrarian discontent had begun to chip away at the feudal system, he appears as ananti-establishment rebel who murders government agents and wealthy landowners. Later variations from times of less social upheaval dispense with the gore and cast Robin as a dispossessed aristocrat with a heart of gold and a love interest, Maid Marian.Academics, meanwhile, have combed the historical record for evidence of a real Robin Hood. English legal records suggest that, as early as the 13th century, Robehod, Rabunhod and other variations had become common epithets for criminals. But what had inspired these nicknames: a fictional tale, an infamous bandit or an amalgam of both? The first literary references to Robin Hood appear in a series of 14th-and 15th-century ballads about a violent yeoman who lived in Sherwood Forest with his men and frequently clashed with the Sheriff of Nottingham. Rather than a peasant, knight or fallen noble, as in later versions, the protagonist of these medieval stories is a commoner. Little John and Will Scarlet are part of this Robin's merry crew-meaning, at the time, an outlaw's gang-but Maid Marian, Friar Tuck and Alan-a-Dale would not enter the legend until later, possibly as part of the May Day rituals.While most contemporary scholars have failed to turn up solid clues, medieval chroniclers took for granted that a historical Robin Hood lived and breathed during the 12th or 13th century. The details of their accounts vary widely, however, placing him in conflicting regions and eras. Not until John Major's History of Greater Britain (1521), for example, is he depicted as a follower of King Richard, one of his defining characteristics in modern times.We may never know for sure whether Robin Hood ever existed outside the verses of ballads and pages of books. And even if we did, fans, young and old, would still surely flock to England's Nottinghamshire region for a tour of the legend's alleged former hangouts, from centuries-old pubs to the Major Oak in Sherwood Forest. What we do know is that the notion of a brave rebel who lives on the outskirts of society, fighting injustice and oppression with his band of companions, has universal appeal-whether he's played by Erroll Flynn, Russell Crowe or even, as on a 1979 episode of The Muppet Show, Kermit the Frog.Which of the following is closest in meaning to the underlined phrase a rite of passage in Paragraph 2?AA milestone event.BA top agenda.CA religious ceremony.DA privileged right.
