23、d as the sabertooth. Yet what compels modern adventurers to do such foolhardy things as jumping off dizzying cliffs or speculating in Internet stocks? Amateur analysts once psychobabbled about a death risk - an old Freudian clich that said risk takers were really driven by subconscious feelings of g

24、uilt. Nowadays scientists say the real roots of such behavior are as likely to be found in the convoluted chemistry of the genes as in the id or the superego.Long before genes were discovered, Darwin suspected that behavior was at least partly inherited. But only recently have scientists working in

25、the burgeoning field of behavioral genetics begun to link specific stretches of DNA with personality traits. Studying the DNA of subjects who were identified as curious and excitable - two of the common characteristics of those who look for novelty and thrills - Israeli scientists found that these p

26、eople had longer versions of a gene known as D4DR than did subjects who were typed as laid-hack and reflective. It quickly became known as the novelty-or thrill-seeking gene. Shortly thereafter, an American team found a second gene, on a different chromosome, that appears to regulate anxiety.Scienti

27、sts have yet to figure out how such genes might work, other than to control the flow of certain chemicals in the bratty. The thrill-seeking gene, for example, seems to facilitate absorption by nerve cells of dopamine, one of the brains chemical messengers and a key modulator of pleasure and emotion.

28、 Similarly, the anxiety gene appears to work by affecting levels of serotonin, a mood chemical linked with feelings of satisfaction. But can such genes actually determine behavior? More important, if we happen to possess them in our chromosomes, will we inevitably grow into high rollers or high dive

29、rs? Not at all, says molecular biologist Dean Hamer, a pioneer in the new field of molecular psychology. Unlike the genes that control physical traits - the color of our eyes, say, or the shape of our nose - such DNA merely Upredisposes/U us to certain behaviors. “Genes are not switches that say sky

30、 or outgoing or happy or sad, “he and co-author Peter Copeland write in their book Living with Our Genes. “Genes are simply chemicals that direct the combination of more chemicals.“ But some chemicals, like dopamine, can have far-flung effects. Because dopamine creates sensations of pleasure, he say

31、s, those who inherit the thrill seeking gene might want to stimulate dopamine production by pushing the danger button, whether with edgy sports for long days or e-trading.（分数：5.00）(1).The writers general attitude towards Freudian theory about risk-taking behavior is _.（分数：1.00）A.appreciativeB.object

35、 After their education was finished, they were supposed to get ready to go out into the real world. But many adults these days are coming back to “schools of continuing education“ and “centers of life-long learning“. They feel that ones education is never really ended, because one is never too old t

36、o learn.A fast-growing number of older students are helping schools that once ignored their needs. Filling empty seats in classrooms from Maine to Hawaii, students who are 25 and older are having a great effect on all fields of higher education. In all, there are 17 million of them. Programs include

37、 courses offered by high schools, local governments, federal agencies, and private groups. But it is at the college level where effects are the greatest. Educators say the registration of older students is caused by a growing feeling of Americans that education is a life-long effort. It has provided

38、 new variety as well as needed dollars to schools, traditionally intended for students in their teens and early twenties.According to Census Bureau estimates, Olin Cook, Direct0r of Higher Education for the state of Arkansas, says: “Adult education will keep the classes filled and the bills paid.“Te

39、achers say that there has been a definite effect on classrooms and course work. Older students are described as more serious and mature, frequently more demanding of instructors, and more willing to contribute personal experiences to discussions. “They realize that they are here to do X,Y,Z, and the

40、y want the professor to teach them that. They are very attentive and concerned.“ A Michigan educator, Elinor P. Waters says that the presence of older students on campus “will take us a step closer to the real world; there will be fewer irrelevant courses and more practical ones“.Why do adults want

41、to re-enter academic life? School administrators say high unemployment is one of the biggest reasons, forcing many Americans to develop new skills. In addition, a large number of women who left school to raise families or who want jobs that require a college diploma are going back to school. College

42、 graduates are returning for second degrees to start new careers. And there are thousands of retired persons who are seeking good use of their free time.Many students feel that they are better prepared for learning than they were when they were younger. For example, Jane Pirozzolo, who will soon rec

43、eive a degree in English from Boston University, graduated from junior college in 1967 and has worked as a secretary since then. Explaining her decision to return to school, she says: “I felt overqualified for the jobs I was doing, and they were becoming increasingly boring. Now I feel I can underst

44、and what the professor wants, and I can study and read better than I could ten years ago. I feel like Im one step ahead of the young students.“Most educators are convinced that the growth of adult learning is an important change in American education. Proof of the great interest in adult education i
