For thousands of years， people have known that the best way to understand a concept is to explain it to others． "While we teach， we learn，" said Roman philosopher Seneca． Now scientists are bringing this ancient wisdom up-to-date． They're documenting why teaching is such a fruitful way to learn， and designing innovative ways for young people to engage in instruction． Researchers have found that students who sign up to tutor others work harder to understand the material，recall it more accurately and apply it more effectively． Student teachers score higher on tests than pupils who're learning only for their own sake． But how can children teach others while learning themselves？ One answer： They can tutor younger kids． Some studies have found that first-born children are more intelligent than their later-born siblings (兄弟姐妹)． This suggests their higher IQs result from the time they spend teaching their siblings． Now educators are experimenting with ways to apply this model to academic subjects． They engage college undergraduates to teach computer science to high school students， who then in turn instruct middle school students on the topic． But the most cutting-edge tool under development is the "teachable agent"-a computerized character who learns， tries， makes mistakes and asks questions just like a real-world pupil． Computer scientists have created an animated(动画的) figure called Betty's Brain， who has been "taught" about environmental science by hundreds of middle school students． Student teachers are motivated to help Betty master certain materials． While preparing to teach， they organize their knowledge and improve their own understanding． And as they explain the information to it， they identify problems in their own thinking． Feedback from the teachable agent further enhances the tutor's learning． The agents' questions force student teachers to think and explain the materials in different ways， and watching the agent solve problems allows them to see their knowledge put into action． Above all， it's the emotions one experiences in teaching that facilitate learning． Student teachers feel upset when their teachable agents fail， but happy when these virtual pupils succeed as they gain pride and satisfaction from someone else's accomplishment． (9)What are researchers rediscovering through their studies？___ A．Seneca's thinking is still applicable today． B．Better learners will become better teachers． C．Human intelligence tends to grow with age． D．Philosophical thinking improves instruction． What do we learn about Betty's Brain？___ A．It is a character in a popular animation． B．It is a teaching tool under development． C．It is a cutting-edge app in digital games． D．It is a tutor for computer science students． How does teaching others benefit student tutors？___ A．It makes them aware of what they are strong at． B．It motivates them to try novel ways of teaching． C．It helps them learn their academic subjects better． D．It enables them to better understand their teachers． What is the key factor that eases student tutors' learning？___ A．Their sense of responsibility． B．Their emotional involvement． C．The learning strategy acquired． D．The teaching experience gained．

A The Internet brings us many advantages. With the Internet, people can send and receive e­mails. On the Internet, people can skim over news. Using the Telnet, the user anywhere on the Internet can log into any other machine on which he has an account. It is possible to use the FTP program to copy files from one machine on the Internet to another. But the Internet also brings us troubles. Internet use seems to cause a fall in psychological(心理的) health, according to research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less often, the two­year study showed. And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net actually seemed to cause the bad feelings. Researchers are puzzled over the results, which were completely opposite to what they had expected. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others. The fact that Internet use reduces time used for family and friends may be the reason for the drop in health, researchers said. Faceless, bodiless ＂virtual＂ (虚拟的) communication may be less psychologically satisfying than actual conversations, and the relationships formed through it may not be so deep. Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives. ＂But it’s important to remember this is not about the technology; it’s about how it is used,＂said one of the researchers. ＂It really points to the need for considering social factors (因素) when you design new inventions.＂ 【小题1】The writer mainly wants to tell us that ___________.

A．Users anywhere on the Internet can log into any other machine. B．The two­year study showed that using the Net seemed to cause the bad feelings. C．People who are already feeling bad spend much more time on the Internet. D．Relationships formed through the Internet are usually deep.

Exercise is one of the few factors with a positive role in long-term maintenance of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical exertion. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to shed pounds said they were combining exercise with their diet.In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts: for example, one would have to briskly walk three miles just to work off the 275 calories in one delicious Danish pastry (小甜饼). Even exercise professionals concede half a point here. "Exercise by itself is a very tough way to lose weight, " says York Onnen, program director of the President's Council on Physical Fitness and Sports.Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.If you have been sedentary (极少活动的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.What is said about the average American in the passage? A.They tend to exaggerate the healthful effect of "light" beer.B.They usually ignore the effect of exercise on losing weight.C.They prefer "light" beer and low-calorie bread to other drinks and food.D.They know the factors that play a positive role in keeping down body weight.Some people dislike exercise because .A.they think it is physically exhaustingB.they find it hard to exercise while on a dietC.they don't think it possible to walk 3 miles every dayD.they find consulting caloric-expenditure charts troublesomeWhat was confirmed by the Boston University Medical Center's study? A.Controlling one's calorie intake is more important than doing exercise.B.Even occasional exercise can help reduce weight.C.Weight reduction is impossible without exercise.D.One could lose ten pounds in a year's time if there's no increase in food intake.What is the author's purpose in writing this article? A.To justify the study of the Boston University Medical Center.B.To stress the importance of maintaining proper weight.C.To support the statement made by York Onnen.D.To show the most effective way to lose weight.
