21世纪大学英语读写基础教程单元七内容讲解1

　　"Why do I have to learn math? I"ll never use this again in my whole life." This kind of complaining can often be heard among students. Is it true that nobody needs math? Well, the author is going to tell you the story...

　　Math, Who Needs It?

　　Carlie Vanwilligen

　　"That"ll be $6.52," the cashier said. I handed her a $10 bill. She looked at it, then looked at me. As I waited, she started writing on a pad of paper. After what seemed like several minutes, she handed me the change. "$4.52 is your change," she smiled.

　　I stared at the change, then at her. "That"s not right," I said. She looked at me, confused. "I gave you a $10, the change would be $3.48." I handed the money back to her.

　　"I"m sorry," she replied. "Our com*r is down, and I have to do this by hand. I"m not very good at math." She counted out my change, and I left.

　　As I think back on this exchange, I feel sad, sad because it wasn"t the first time it had happened, sad because I know it won"t be the last. I taught high school math for years, and every year, the conversation was the same: "Why do I have to learn this? This isn"t important. I"ll never use this again in my whole life."

　　Unfortunately, students don"t see the eventual impact of studying a subject. And when that subject is math, they see the value even less. I no longer teach full-time, but I look back on those conversations and think about how my reactions changed each year. The first year I taught, the question caught me off guard. "Because" was my standard answer. The second year, my response was similar, "If you want to graduate, you learn this stuff." It took me until my third year of teaching to realize that, if I genuinely wanted students to learn, they needed motivation. So, instead of my standard "because" and "if you want to pass" answers, I asked them what they"d like to do when they graduate—or when they "grow up". For each career path, I had "math" that they needed to know in order to be successful. For the construction workers, architects, and engineers, there was the geometry involved in getting a building to stand solidly. For the prospective teacher, it was the statistics involved in seeing if your tests were fair to the students. For the prospective "I want to be a stay-at-home mom", there was the calculating involved in maintaining a household. For the financial wizard wanna-be, there was the understanding of economics that comes with being a successful investor or accountant. For the stubborn, who insisted they didn"t want to be anything, and didn"t need math, a simple role-play involving them being "ripped-off" when they couldn"t make change drove my point home.

　　Who needs math? We all do! We use it every day. Not only that, but the problem solving we learned during the days of "if one train leaves Springfield at 6:00pm travelling east at 75mph", can now help us with a myriad of "*" crises. Do I have enough gas to get to work and back without filling the tank? Which bills do I pay and when in order to have enough money in the bank? How much grass seed do I need to cover that 10"×10" bare patch in the front yard?

　　For those still teaching, it is using these examples, and developing activities for students that bring the reality of math into their worlds. For parents, the same holds true. When your child complains that he or she "doesn"t get" math, give your child an example. Take your child to the grocery store. Give your child $10. Tell your child to provide a dinner for the family, complete with the four basic food groups and dessert, for that $10. Show your child the importance of thinking mathematically. It will do your child some good—who knows, you might learn something too!

21世纪大学英语读写基础教程Unit8内容介绍1

　　When a seven-year-old boy declared that he had fallen in love with a seven-year-old girl, the *s laughed, and the young ones did not understand why. In their eyes, their love was serious and important indeed.

　　Young and in Love

　　Jeanne Marie Laskas

　　Ryan has never had a girlfriend. Not because he is against the idea, but because it has never actually occurred to him. He is 7.

　　When Ryan"s father tells him about Katie, a girl who will also be at the weekend getaway, Ryan starts bouncing around as if hit with an electric charge. Maybe it"s just that there will be a kid the same age there. He gets so sick of being the only kid around when he and his dad do stuff.

　　Or maybe it"s that Katie is reported to like a lot of the same things Ryan likes. Maybe it"s the words his father says, the words that Ryan will not be able to get out of his ears: "They say she has 311 Pokemon cards."

　　Ryan has never met anyone with 311 Pokemon cards. He himself has 204. He gathers all of his and puts them in a box, so that he can show them to the girl named Katie.

　　The place is filled with grown-ups when he arrives, old friends drinking beer. Ryan wanders around, saying, "Where"s Katie?" until someone points to the family room. He charges in there, hoping it"s true.

　　He sees her there curled up on a couch with her mother, watching "Rug-rats." She has long brown hair and big green eyes. "I"m Ryan!" he announces.

　　She looks at him. She says something Ryan has never heard before. She says: "I have pneumonia."

　　Ryan has never met anyone with pneumonia before. There is no denying it any longer. This girl is special.

　　He says, "Do you want to see my Pokemon cards?" She stands up, takes him away to compare collections. She does not brag about the fact that she has more cards than he does, which you have to admit is a class act.

　　A half-hour goes by. Ryan and Katie return to the family room, where many of the grown-ups have gathered. "He asked me to be his girlfriend!" Katie announces.

　　"I have a crush on her!" Ryan says.

　　"I had two boyfriends before," Katie says. "But they were annoying. Not like Ryan. He is the best boyfriend I have ever had."

　　Katie and Ryan can"t understand why the grown-ups are laughing; they don"t understand that sweethearts don"t just come out and say these things. Love isn"t like this. Love is something that happens in code. Love is a complicated game of pretending not to love, not to care, so that the other one will have no choice but to love and care. At least this is how it works when you"re... mature.

　　They spend the day comparing Pokemon cards. It feels as if they could do this forever. Katie gives Ryan a Psyduck card, and not just because she has six of them. She gives it to him because Psyduck is her very favorite Pokemon character.

　　When it is time to go, Ryan asks if someone can please show him a map, so he can see how far away Katie lives. His father tells him it"s a few hundred miles. Ryan feels like throwing up. Katie says, "How about e-mail?" Katie has all the good ideas. Katie"s mom and Ryan"a dad agree to set up accounts for the kids.

　　On the drive home, Ryan holds his Psyduck card. He flips it over. He places it next to his cheek. As soon as he walks in the door, he turns on his dad"s com*r. For his screen name he chooses Psyduck plus a few of Katie"s favorite numbers, and KRKRKR for a password, as many K"s next to as many R"s as he can fit. In his message he says, "Dear Katie, Hi it"s me. What"s up? I was just wondering (what was up.) I miss you. Love, Ryan."

　　He awaits her response. He waits an hour. By the second hour, he is sitting at the com*r in tears. "What happened?" he wails to his dad. He wonders if she forgot about him, if any of it was really true. The answer could mean everything. This is love at ground zero. This is a trial run for a heart that will one day occupy a man.

　　"You"ve got mail," the com*r says. And there she is. "Dear Ryan," she writes. "I just got home. I miss you. I am so glad I am your girlfriend. Love, Katie."

　　Ryan is so happy he can hardly type the words back. "I got your message!" he writes. "It was a great message. It"s the only message I have ever got, so it is and always will be my favorite."

21世纪大学英语读写基础教程The Future课文解读1

　　What will our future be like? What might happen in the year 2144? How far can your imagination take you into the future? Let"s see what a newspaper in New Zealand tells us.

　　The Future

　　Will the future be one of robots and spaceships, or meditation and organic food? Today and next Wednesday The Post steps into the future, and asks the experts what they think the world of tomorrow will be like.

　　Imagine you are holding the December 11, 2144 edition of The Evening Post. It won"t be made of paper, but a thin screen that can be folded up and put in your pocket or bag. You"ll use the same screen tomorrow, when the day"s news will be beamed to its tiny modem via satellite.

　　The modem will chatter away all day, updating stories from around the world as they happen, complete with moving pictures and sound. A retina scanner will follow your eye, scrolling each page as you get near the bottom. The paper"s com*r will record which stories interest you most and design a custom menu every time you switch it on.

　　Let"s see what"s happening today. Again, the big local story is the disappearing apartment blocks at Happy Valley. Built over an old landfill, this expensive new development is slowly sinking into the ground. Engineers suspect plastic milk bottles dumped with their caps screwed on in the late-20th century are bursting under the weight of the buildings. "People back then," says Wellington"s Mayor in a live interview, "were pretty stupid."

　　Overseas a power failure at a cryo-prison in Alabama during the holiday weekend saw 50,000 inmates thawed prematurely, and in Bangladesh monsoon floods have wiped out hundreds of villages. Some things don"t change.

　　In reality, we can"t predict what the pages of this newspaper will contain 144 years from now because we can"t predict the future. But in two weeks we will arrive in the new millennium, a date long held up as the future, but which will soon represent a new beginning.

　　Thirty years ago it was expected that by 2000 commuters would fly to work on highways in the sky, that robots with pinnies would do the vacuuming, that humans would have colonised our near planets and the moon.

　　Our cars are still stuck firmly on the ground, although even the most basic family runabout has a powerful electronic brain which tells it how much fuel to use and figures out in milliseconds how to save the occupants in a crash.

　　We still do the vacuuming ourselves, although our ovens tell us when food is ready. We can download whole libraries through our home com*rs and view snaps of friends on the other side of the world seconds after they are taken.

　　We have yet to live anywhere other than Earth, although missions into space have allowed us to develop new medicines, information chips and superconductors to make life better down here.

　　Who would have believed we"d be altering the genetic make-up of animals so they can grow replacement organs for us? Who"d have believed the drink machine in the foyer dials for supplies when it senses it"s getting low?

　　At the dawn of the new millennium the future seems to be coming at us at a frightening pace, with the world seeming to change almost weekly.

　　What then, will it be like in 100 years? 500? 1000? Will it be a technological future with space hotels, rocket cars, genetically engineered people and automated homes? Or will it be an organic future with a new emphasis on spirituality and nature?

　　Will humankind still be blighted by war? Will we be able to cure cancer? Will we still get married? What sort of world will our children inherit?

　　Over the past few months The Post has been asking experts in their fields to take an educated, but fanciful, guess. None claims to be able to tell the future, but by tracking current trends they can give us an idea of what to expect in the world of tomorrow.

　　You won"t be around to read the December 11, 2144 edition of The Evening Post, but this is the next best thing.

　　Welcome to the future.

　　"Why do I have to learn math? I"ll never use this again in my whole life." This kind of complaining can often be heard among students. Is it true that nobody needs math? Well, the author is going to tell you the story...

　　Math, Who Needs It?

　　Carlie Vanwilligen

　　"That"ll be $6.52," the cashier said. I handed her a $10 bill. She looked at it, then looked at me. As I waited, she started writing on a pad of paper. After what seemed like several minutes, she handed me the change. "$4.52 is your change," she smiled.

　　I stared at the change, then at her. "That"s not right," I said. She looked at me, confused. "I gave you a $10, the change would be $3.48." I handed the money back to her.

　　"I"m sorry," she replied. "Our computer is down, and I have to do this by hand. I"m not very good at math." She counted out my change, and I left.

　　As I think back on this exchange, I feel sad, sad because it wasn"t the first time it had happened, sad because I know it won"t be the last. I taught high school math for years, and every year, the conversation was the same: "Why do I have to learn this? This isn"t important. I"ll never use this again in my whole life."

　　Unfortunately, students don"t see the eventual impact of studying a subject. And when that subject is math, they see the value even less. I no longer teach full-time, but I look back on those conversations and think about how my reactions changed each year. The first year I taught, the question caught me off guard. "Because" was my standard answer. The second year, my response was similar, "If you want to graduate, you learn this stuff." It took me until my third year of teaching to realize that, if I genuinely wanted students to learn, they needed motivation. So, instead of my standard "because" and "if you want to pass" answers, I asked them what they"d like to do when they graduate—or when they "grow up". For each career path, I had "math" that they needed to know in order to be successful. For the construction workers, architects, and engineers, there was the geometry involved in getting a building to stand solidly.

For the prospective "I want to be a stay-at-home mom", there was the calculating involved in maintaining a household. For the financial wizard wanna-be, there was the understanding of economics that comes with being a successful investor or accountant. For the stubborn, who insisted they didn"t want to be anything, and didn"t need math, a simple role-play involving them being "ripped-off" when they couldn"t make change drove my point home.

　　Who needs math? We all do! We use it every day. Not only that, but the problem solving we learned during the days of "if one train leaves Springfield at 6:00pm travelling east at 75mph", can now help us with a myriad of "adult" crises. Do I have enough gas to get to work and back without filling the tank? Which bills do I pay and when in order to have enough money in the bank? How much grass seed do I need to cover that 10"×10" bare patch in the front yard?

　　For those still teaching, it is using these examples, and developing activities for students that bring the reality of math into their worlds. For parents, the same holds true. When your child complains that he or she "doesn"t get" math, give your child an example. Take your child to the grocery store. Give your child $10. Tell your child to provide a dinner for the family, complete with the four basic food groups and dessert, for that $10. Show your child the importance of thinking mathematically. It will do your child some good—who knows, you might learn something too!

21世纪大学英语读写教程第四册Unit1课文讲解2

　　Michael Ryan

　　As a young boy, Albert Einstein did so poorly in school that teachers thought he was slow. The young Napoleon Bonaparte was just one of hundreds of artillery lieutenants in the French Army. And the teenage George Washington, with little formal education, was being trained not as a soldier but as a land surveyor.

　　Despite their unspectacular beginnings, each would go on to carve a place for himself in history. What was it that enabled them to become great? Were they born with something special? Or did their greatness have more to do with timing, devotion and, perhaps, an uncompromising personality?

　　For decades, scientists have been asking such questions. And, in the past few years, they have found evidence to help explain why some people rise above, while others—similarly talented, perhaps—are left behind. Their findings could have implications for us all.

　　Who is great? Defining who is great depends on how one measures success. But there are some criteria. "Someone who has made a lasting contribution to human civilization is great," said Dean Keith Simonton, a professor of psychology at the University of California at Davis and author of the 1994 book Greatness: Who Makes History and Why. But he added a word of caution: "Sometimes great people don"t make it into the history books. A lot of women achieved great things or were influential but went unrecognized."

　　In writing his book, Simonton combined historical knowledge about great figures with recent findings in genetics, psychiatry and the social sciences. The great figures he focused on include men and women who have won Nobel Prizes, led great nations or won wars, composed symphonies that have endured for centuries, or revolutionized science, philosophy, politics or the arts. Though he doesn"t have a formula to define how or why certain people rise above (too many factors are involved), he has come up with a few common characteristics.

　　A "never surrender" attitude. If great achievers share anything, said Simonton, it is an unrelenting drive to succeed. "There"s a tendency to think that they are endowed with something super-normal," he explained. "But what comes out of the research is that there are great people who have no amazing intellectual processes. It"s a difference in degree. Greatness is built upon tremendous amounts of study, practice and devotion."

　　He cited Winston Churchill, Britain"s prime minister during World War II, as an example of a risk-taker who would never give up. Thrust into office when his country"s morale was at its lowest, Churchill rose brilliantly to lead the British people. In a speech following the Allied evacuation at Dunkirk in 1940, he inspired the nation when he said, "We shall not flag or fail. We shall go on to the end...We shall never surrender."

　　Can you be born great? In looking at Churchill"s role in history—as well as the roles of other political and military leaders—Simonton discovered a striking pattern: "Firstborns and only children tend to make good leaders in time of crisis: They"re used to taking charge. But middle-borns are better as peacetime leaders: They listen to different interest groups better and make the necessary compromises. Churchill, an only child, was typical. He was great in a crisis, but in peacetime he was not effective—not even popular."

　　Timing is another factor. "If you took George Washington and put him in the 20th century he would go nowhere as a politician," Simonton declared. "He was not an effective public speaker, and he didn"t like shaking hands with the public. On the other hand, I"m not sure Franklin Roosevelt would have done well in Washington"s time. He wouldn"t have had the radio to do his fireside chats."

　　Can you be too smart? One surprise among Simonton"s findings is that many political and military leaders have been bright but not overly so. Beyond a certain point, he explained, other factors, like the ability to communicate effectively, become more important than innate intelligence as measured by an IQ test. The most intelligent U.S. Presidents, for example—Thomas Jefferson, Woodrow Wilson and John F. Kennedy—had a hard time getting elected, Simonton said, while others with IQs closer to the average (such as Warren G. Harding) won by landslides. While political and economic factors also are involved, having a genius IQ is not necessary to be a great leader.

　　In the sciences, those with "genius level" IQs do have a better chance at achieving recognition, added Simonton. Yet evidence also indicates that overcoming traditional ways of thinking may be just as important.

　　He pointed to one recent study where college students were given a set of data and were asked to see if they could come up with a mathematical relation. Almost a third did. What they did not know was that they had just solved one of the most famous scientific equations in history: the Third Law of Planetary Motion, an equation that Johannes Kepler came up with in 1618.

　　Kepler"s genius, Simonton said, was not so much in solving a mathematical challenge. It was in thinking about the numbers in a unique way—ap*ing his mathematical knowledge to his observations of planetary motion. It was his boldness that set him apart.

　　Love your work. As a child, Einstein became fascinated with the way magnets are drawn to metal. "He couldn"t stop thinking about this stuff," Simonton pointed out. "He became obsessed with problems in physics by the time he was 16, and he never stopped working on them. It"s not surprising that he made major contributions by the time he was 26."

　　"For most of us, it"s not that we don"t have the ability," Simonton added, "it"s that we don"t devote the time. You have to put in the effort and put up with all the frustrations and obstacles."

　　Like other creative geniuses, Einstein was not motivated by a desire for fame, said Simonton. Instead, his obsession with his work was what set him apart.

　　Where such drive comes from remains a mystery. But it is found in nearly all creative geniuses—whether or not their genius is acknowledged by contemporaries.

　　"Emily Dickinson was not recognized for her poetry until after her death," said Simonton. "But she was not writing for fame. The same can be said of James Joyce, who didn"t spend a lot of time worrying about how many people would read Finnegans Wake."

　　Today, researchers have evidence that an intrinsic passion for one"s work is a key to rising above. In a 1985 study at Brandeis University conducted by Teresa Amabile, now a professor of business administration at Harvard University, a group of professional writers—none famous—were asked to write a short poem. Each writer was then randomly placed in one of three groups: One group was asked to keep in mind the idea of writing for money; another was told to think about writing just for pleasure; and a third group was given no instruction at all.

　　The poems then were submitted anonymously to a panel of professional writers for evaluation. The poetry written by people who thought about writing for money ranked lowest. Those who thought about writing just for pleasure did the best. "Motivation that comes from enjoying the work makes a significant difference, "Amabile said.

　　Conversational Ballgames

　　Nancy Masterson Sakamoto

　　After I was married and had lived in Japan for a while, my Japanese gradually improved to the point where I could take part in simple conversations with my husband, his friends, and family. And I began to notice that often, when I joined in, the others would look startled, and the conversation would come to a halt. After this happened several times, it became clear to me that I was doing something wrong. But for a long time, I didn"t know what it was.

　　Finally, after listening carefully to many Japanese conversations, I discovered what my problem was. Even though I was speaking Japanese, I was handling the conversation in a Western way.

　　Japanese-style conversations develop quite differently from western-style conversations. And the difference isn"t only in the languages. I realized that just as I kept trying to hold western-style conversations even when I was speaking Japanese, so were my English students trying to hold Japanese-style conversations even when they were speaking English. We were unconsciously playing entirely different conversational ballgames.

　　A western-style conversation between two people is like a game of tennis. If I introduce a topic, a conversational ball, I expect you to hit it back. If you agree with me, I don"t expect you sim* to agree and do nothing more. I expect you to add something — a reason for agreeing, another example, or a remark to carry the idea further. But I don"t expect you always to agree. I am just as happy if you question me, or challenge me, or completely disagree with me. Whether you agree or disagree, your response will return the ball to me.

　　And then it is my turn again. I don"t serve a new ball from my original starting line. I hit your ball back again from where it has bounced. I carry your idea further, or answer your questions or objections, or challenge or question you. And so the ball goes back and forth.

　　If there are more than two people in the conversation, then it is like doubles in tennis, or like volleyball. There"s no waiting in line. Whoever is nearest and quickest hits the ball, and if you step back, someone else will hit it. No one stops the game to give you a turn. You"re responsible for taking your own turn and no one person has the ball for very long.

　　A Japanese-style conversation, however, is not at all like tennis or volleyball, it"s like bowling. You wait for your turn, and you always know your place in line. It depends on such things as whether you are older or younger, a close friend or a relative stranger to the previous speaker, in a senior or junior position, and so on.

　　The first thing is to wait for your turn, patiently and politely. When your moment comes, you step up to the starting line with your bowling ball, and carefully bowl it. Everyone else stands back, making sounds of polite encouragement. Everyone waits until your ball has reached the end of the lane, and watches to see if it knocks down all the pins, or only some of them, or none of them. Then there is a pause, while everyone registers your score.

　　Then, after everyone is sure that you are done, the next person in line steps up to the same starting line, with a different ball. He doesn"t return your ball. There is no back and forth at all. And there is always a suitable pause between turns. There is no rush, no impatience.

　　No wonder everyone looked startled when I took part in Japanese conversations. I paid no attention to whose turn it was, and kept snatching the ball halfway down the alley and throwing it back at the bowler. Of course the conversation fell apart, I was playing the wrong game.

　　This explains why it can be so difficult to get a western-style discussion going with Japanese students of English. Whenever I serve a volleyball, everyone just stands back and watches it fall. No one hits it back. Everyone waits until I call on someone to take a turn. And when that person speaks, he doesn"t hit my ball back. He serves a new ball. Again, everyone just watches it fall. So I call on someone else. This person does not refer to what the previous speaker has said. He also serves a new ball. Everyone begins again from the same starting line, and all the balls run parallel. There is never any back and forth.

　　Now that you know about the difference in the conversational ballgames, you may think that all your troubles are over. But if you have been trained all your life to play one game, it is no simple matter to switch to another, even if you know the rules. Tennis, after all, is different from bowling.
