Many executives have assumed that this tool is beyond their grasp, available only to the charismatic (有魅力的) and the eloquent. Over the past several decades, though, experimental psychologists have learned which methods reliably lead people to concede, comply, or change. Their research shows that persuasion is governed by several principles that can be taught and applied.The first principle is that people are more likely to follow someone who is similar to them than someone who is not. Wise managers, then, ask peers to help make their cases. Second, people are more willing to cooperate with those who are not only like them but who like them, as well. So its worth the time to uncover real similarities and offer genuine praise.Third, experiments confirm the intuitive truth that people tend to treat you the way you treat them. Its sound policy to do a favor before seeking one. Fourth, individuals are more likely to keep promises they make voluntarily and clearly. The message for managers here is to get commitments in writing. Fifth, studies show that people really do defer to (服从) experts. So before they attempt to exert influence, executives should take pains to establish their own expertise and not assume that its self-evident. Finally, people want more of a commodity when its scarce; it follows, then, that exclusive information is more persuasive than widely available data.Experiments have confirmed the assumption of many executives.ARightBWrongCNot mentioned3、Courageous people think quickly and act withouthesitation.AcomplaintBconsiderationCdelayDanxiety4、They didntrealizehow serious the problem was.AknowBforgetCdoubtDremember5、I want to provide my boys with adecenteducation.AprivateBgeneralCgoodDSpecial6、根据材料，回答问题。Eat More, Weigh Less, Live LongerClever genetic detective work may have found out the reason why a near starvation dietprolongs the life of many animalsRonald Kahn at Harvard Medical School in Boston, US, and his colleagues have been ableto extend the lifespan (寿命) of mice by 18 per cent by blocking the rodents (啮齿动物) increase of fat in specific cells This suggests that thinness - and not necessarily diet -promotes long life in calorie (卡路里) restricted animalsIts very cool work says aging researcher Cynthia Kenyon of the University of California, San Francisco These mice eat all they want, lose weight and live longer Its like heaven.Calorie restrition dramatically extends the lifespan of organisms as different as worms and rodents Whether this works in humans is still unknown, partly because few people are willing to submit to such a strict dietBut many researchers hope they will be able to trigger the same effect with a drug once they understand how less food leads to a longer life One theory is that eating less reduces the increase of harmful things that can damage cells But Kahns team wondered whether the animals simply benefit by becoming thinTo find out, they used biology tricks to disrupt the insulin (胰岛素) receptor (受体) gene in lab mice - but only in their fat cells Since insulin is needed to help fat cells store fat, these animals were protected against becoming fat, explains KahnThis slight genetic change in a single tissue had dramatic effects By three months of age, Kahn, thoses modified mice had up to 70 per cent less body fat than normal control mice, despite the fact that they ate 55 per cent more food per gram of body weight In addition, their lifespan increased The average control mouse lived 753 days, while the thin rodents averaged a lifespan of 887 days After three years, all the control mice had died, but one-quarter of the modified rodents were still alive That they get these effects by just manipulating the fat cells is controversial, says Leonard Guarente of the Massachusetts Institute of Technology, who studies calorie restriction and aging But Guarente says Kahn has yet to prove that the same effect is responsible for increased lifespan in calorie-restricted animals It might be the same effect or there might be two routes to long life, he points out, and that would be very interesting Ronald Kahn and his colleagues can make mice live longer by_Aoffering them less foodBgiving them a balanced dietCdisrupting the specific genes in their fat cellsDpreventing them growing larger7、 The economy continued toexhibittendency of decline in September.AplayBsendCshowDtell8、Television advertisements do more thanmerelyreflect dominant ideologies.AexactlyBfaithfullyCrepeatedly
