单选题 The cellphone, a device we have lived with for more than a decade, offers a good example of a popular technology's unforeseen side effects. More than one billion are {{U}}(1) {{/U}} use around the world, and when asked, their {{U}}(2) {{/U}} say they love their phones for the safety and convenience {{U}}(3) {{/U}} provide.

单选题I hear many parents complaining that their teenage children are rebelling. I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own two feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own, most of them are clutching at one another's hands for courage. They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up just by listening to the same record. Their reason for thinking or acting in this way is that the crowd is doing it. It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Industry has firmly carved out a teenage market. These days every teenager can learn from the advertisements what a teenager should have and be. And many of today's parents have come to award high marks for the popularity of their children. All this adds up to a greater barrier for the teenager who wants to find his or her own path. But the barrier is worth climbing over. The path is worth following. Find yourself. Be yourself. Popularity will come--with the people who respect you for whom you are. That's the only kind of popularity that really counts.

单选题Those close to him are ______ that he hopes to stay on till the end of his term.

单选题In spite of "endless talk of difference," American society is an amazing machine for homogenizing people. There is "the democratizing uniformity of dress and discourse, and the casualness and absence of deference" characteristic of popular culture. People are absorbed into "a culture of consumption" launched by the 19th-century department stores that offered " vast arrays of goods in an elegant atmosphere. Instead of intimate shops catering to a knowledgeable elite," these were stores" anyone could enter, regardless of class or background. This turned shopping into a public and democratic act. " The mass media, advertising and sports are other forces for homogenization. Immigrants are quickly fitting into this common culture, which may not be altogether elevating but is hardly poisonous. Writing for the National Immigration Forum, Gregory Rodriguez reports that today's immigration is neither at unprecedented levels nor resistant to assimilation. In 1998 immigrants were 9.8 percent of population; in 1990,13.6 percent. In the 10 years prior to 1990,3.1 immigrants arrived for every 1,000 residents; in the 10 years prior to 1890,9.2 for every 1,000. Now, consider three indices of assimilation--language, home ownership and intermarriage. The 1990 Census revealed that "a majority of immigrants from each of the fifteen most common countries of origin spoke English 'well' or 'very well' after ten years of residence. "The children of immigrants tend to be bilingual and proficient in English. " By the third generation, the original language is lost in the majority of immigrant families. " Hence the description of America as a "graveyard" for languages. By 1996 foreign-born immigrants who had arrived before 1970 had a home ownership rate of 75.6 percent, higher than the 69.8 percent rate among native-born Americans. Foreign-born Asians and Hispanics "have higher rates of intermarriage than do U.S.-born whites and blacks. "By the third generation, one third of Hispanic women are married to non-Hispanics, and 41 percent of Asian-American women are married to non-Asians. Rodriguez notes that children in remote villages around the world are fans of superstars like Arnold Schwarzenegger and Garth Brooks, yet "some Americans fear that immigrants living within the United States remain somehow immune to the nation's assimilative power." Are there divisive issues and pockets of seething anger in America? Indeed. It is big enough to have a bit of everything. But particularly when viewed against America's turbulent past, today's social indices hardly suggest a dark and deteriorating social environment.

单选题For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the U.S. had acquired when it purchased Louisiana, and the Appolo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war. Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone before. Today Mars looms (隐约出现) as humanity's next great terra incognita (未探明之地). And with doubtful prospects for a short-term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet's reddish surface. Could it be that science, which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: are there experiments that only humans could do on Mars? Could those experiments provide insights profound enough to justify the expense of sending people across interplanetary space? With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite (陨石) from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science, the prevalence of life in the universe.

单选题{{B}}Passage Four{{/B}} Elephants who paint aren't new. Paintings by Ruby, an Asian elephant who lived at the Phoenix Zoo in Arizona, sold for up to $ 5,000 in the late 1980s, said Dick George, a consultant with the zoo. "Ruby was about seven months old when she first came to the zoo," said George. "She lived with a goat and some chickens, but she didn't have an elephant companion for a number of years. She spent a lot of time drawing in the dirt with a stick to make her days more stimulating. Her keeper bought her some art sup- plies." George said, "Ruby was excited about painting right from the beginning." The elephants at the art academies in the Southeast Asia are taught to hold a paintbrush with the tip of their trunks. Initially, the keeper guides the elephant's trunk over the canvas(画布) and offers rewards for good performance. "It only takes a few hours to a day to teach them," said Mia Fineman, an art historian whose book When Elephants Paint is an illustrated history of the Asian Elephant Art and Consrvation Project.

单选题Each semester, Andrew Tom receives a term bill outlining his expenses: tuition, dorm fee, student center fee, recreation fee, resident activity fee, health insurance. If only the rest of his expenses were as easy to quantify. "It's like you start out the semester with plenty of money and then $ 20 for dinner out here and $100 at the department store there, it's gone," said Tom, a Northeastern University third-year student. "And there are so many things you need like toothpaste or laundry detergent (洗涤剂) that you don't think about until you get here and need it." From the books lining their shelves to the fashionable clothes filling their closets, college students say the expenses of a college education go well beyond tuition and a dining hall meal plan. Many say they arrive on campus only to be overwhelmed by unexpected costs from sports fees to the actual price of a slice of pizza. Balancing a job with schoolwork, especially at colleges known for their heavy workloads like Harvard and MIT, can be tough. So can the pressure students often feel to financially keep pace with their friends. "When you get dragged along shopping, you're going to spend money; if you get dragged to a party and everyone wants to take a cab but you're cheap and want to take a bus. Chances are you"ll end up sharing the fee for the cab," said Tom. "I guess you could say no, but no one wants to be the only one eating in the snack bar while your friends are ont to dinner. " Max Cohen, a biology major at MIT, said he is accustomed to watching fellow students spend $ 40 a night to have dinner delivered or $ 50 during a night out at a bar. During the school's recent spring break, friends on trips for the week posted away messages that read like a world map—Paris, Rome, Tokyo. "Meanwhile I stay home and work," said Cohen. "I didn't realize when I came here how much money I would spend or how hard I would have to work to get by." It is a lesson some younger students learn quickly. Others, surrounded by credit card offers, go into debt, or worse, are forced to leave school. "A lot of people don't think twice about how much they spend," said a first-year student at MIT, "and you feel the pressure sometimes to go along with them./
