单选题In the late 1960s, a television producer named Joan Gantz Cooney set out to start an epidemic. Her target was three-, four-, and five-year-olds. Her agent of infection was television, and the "virus" she wanted to spread was literacy. The show would last an hour and run five days a week, and the hope was that if that hour was contagious enough it could serve as an educational Tipping Point; giving children from disadvantaged homes a leg up once they began elementary school, spreading prolearning values from watchers to nonwatchers, infecting children and their parents, and lingering long enough to have an impact well after the children stopped watching the show. Cooney probably wouldn"t have used these concepts or described her goals in precisely this way. But what she wanted to do, in essence, was create a learning epidemic to counter the prevailing epidemics of poverty and illiteracy. She called her idea Sesame Street. By any measure, this was an audacious idea. Television is a great way to reach lots of people, very easily and cheaply. It entertains and dazzles. But it isn"t a particularly educational medium. Gerald Lesser, a Harvard University psychologist who joined with Cooney in founding Sesame Street, says that when he was first asked to join the project, back in the late 1960s, he was skeptical. "I had always been very much into fitting how you teach to what you know about the child, " he says. "You try to find the kid"s strengths, so you can play to them. You try to understand the kid"s weaknesses, so you can avoid them. Then you try and teach that individual kid"s profile ... Television has no potential, no power to do that. " Good teaching is interactive. It engages the child individually. It uses all the senses. It responds to the child. But a television is just a talking box. In experiments, children who are asked to read a passage and are then tested on it will invariably score higher than children asked to watch a video of the same subject matter. Educational experts describe television as "low involvement. " Television is like a strain of the common cold that can spread like lightning through a population, but only causes a few sniffles and is gone in a day. But Cooney and Lesser and a third partner—Lloyd Morrisett of the Markle Foundation in New York—set out to try anyway. They enlisted some of the top creative minds of the period. They borrowed techniques from television commercials to teach children about numbers. They used the live animation of Saturday morning cartoons to teach lessons about learning the alphabet. They brought in celebrities to sing and dance and star in comedy sketches that taught children about the virtues of cooperation or about their own emotions. Sesame Street aimed higher and tried harder than any other children"s show had, and the extraordinary thing was that it worked. Virtually every time the show"s educational value has been tested—and Sesame Street has been subject to more academic scrutiny than any television show in history—it has been proved to increase the reading and learning skills of its viewers. There are few educators and child psychologists who don"t believe that the show managed to spread its infectious message well beyond the homes of those who watched the show regularly. The creators of Sesame Street accomplished something extraordinary, and the story of how they did that is a marvelous illustration of a rule of the Tipping Point, the Stickiness Factor. They discovered that by making small but critical adjustments in how they presented ideas to preschoolers, they could overcome television"s weakness as a teaching tool and make what they had to say memorable. Sesame Street succeeded because it learned how to make television sticky.

单选题Every man is a philosopher. Every man has his own philosophy of life and his special view of the universe. Moreover, his philosophy is important, more important perhaps than he himself knows. It determines his treatment of friends and enemies, his conduct when alone and in society, his attitude towards his home, his work, and his country, his religious beliefs, his ethical standards, his social adjustment and his personal happiness. Nations, too, through the political or military party in power, have their philosophers of thought and action. Wars are waged and revolutions incited because of the clash of ideologies, the conflict of philippics. It has always been so. World War II is but the latest and most dramatic illustration of the combustible nature of differences in social and political philosophy. Philosophy, says Plato, begins with wonder. We wonder about the destructive fury of earthquakes , floods, storms, drought, pestilence, famine, and fire, the mysteries of birth and death , pleasure and pain, change and permanence, cruelly and kindness, instincts and ideals, mind and body, the size of the universe and man"s place in it. Our questions are endless. What is man? What is Nature? What is justice? What is duty? Alone among the animals man is concerned about his origin and end, about his purposes and goals, about the meaning of life and the nature of reality. He alone distinguishes between beauty and ugliness, good and evil, the better and the worse. He may be a member of the animal kingdom, but he is also a citizen of the world of ideas and values. Some of man"s questions have had answers. Where the answer is clear, we call it science or art and move on to higher ground and a new vista of the world. Many of our questions, however, will never have final answers. Men will always discuss the nature of justice and right, the significance of evil, the art of government, the relation of mind and matter, the search for truth, the quest for happiness, the idea of God, and the meaning of reality. The human race has reflected so long and so often on these problems that the same patterns of thought recur in almost every age. We should know what these thoughts are. We should know what answers have been suggested by those who have most influenced ancient and modern thought. We shall want to do our own thinking and find our own answers. It is, however, neither necessary nor advisable to travel alone. Others have helped dispel the darkness, and the light they have kindled may also illuminate our way.
