7、 at one or two aspects of the way a mother behaves towards her baby. The usual fondling, cuddling and cleaning require little comment, but the position in which she holds the baby against her body when resting is rather revealing. Careful studi es have shown the fact that 80 percent of mothers hold

8、their infants in their left arms, ho lding them against the left side of their bodies. If asked to explain the significance of thi s preference most people reply that it is obviously the result of the predominance of right -handedness in the population. By holding the babies in their left arms, the

9、mothers keep their dominant arm free for manipulations. But a detailed analysis shows that this is not t he casE True, there is a slight difference between right-handed and left-handed females。 b ut not enough to provide adequate explanation. It emerges that 83 percent of right-handed mothers hold t

10、he baby on the left side, but so do 78 percent of left-handed mothers. In other words, only 22 percent of the left-handed mothers have their dominant hands free fo r actions. Clearly there must be some other, less obvious explanation. The only other clue comes from the fact that the heart is on the

11、side of the mother s body. Could it be that the sound of her heartbeat is the vital factor? And in what way? Thinking along these lines it was argued that perhaps during its existence inside the bod y of the mother the unborn baby get used to the sound of the heart beat. If this is so, th en the re-

12、discovery of this familiar sound after birth might have a claiming effect on the infant, especially as it has just been born into a strange and frighteningly new worlD if t his is so then the mother would, somehow, soon arrive at the discovery that her baby is more at peace if held on the left again

13、st her heart than on the right. 16 We can learn a lot by observing the position in which a mother holds her baby a gainst her body. A Right B Wrong C Not mentioned 17 Most left-handed women feel comfortable by holding their babies in their left arm and keep the right arm free. A Right B Wrong C Not

14、mentioned 18 The number of right-handed mothers who hold the baby on the left side exceeds t hat of left-handed ones by 22%. A Right B Wrong C Not mentioned 19 The fact that most left-handed mothers hold the baby on their left side renders th e first explanation unsustainable. A Right B Wrong C Not

15、mentioned 20 The fact that the heart is on the left side of the mothers body provides the most convincing explanation of all. A Right B Wrong C Not mentioned 21 A baby held in the right arm of its mother can be easily frightened. A Right B Wrong C Not mentioned 22 The writers explanation of the phen

17、 and fortified by many years of experience and knowledge, they may have a mu ch better idea of how to spend their time enjoyably than they did in their youth. And not all enjoyment is restricted to the mental or philosophical. Healthy physical activity remai ns quite possible for most of us well int

18、o our later years. Old people sometimes display surprising freedom and forthrightness in the expression of their thoughts and feelings, and an ability to transmit affection. It is as though some o f the rituals which constrict us in earlier life fall away. But a higher percentage of people suffer fr

19、om emotional distress in old age than at a ny other time in adult life, and the gap between need and care is often filled by dubious measures, such as heavy-handed prescription of medicinE For many years it was assumed that old people were not appropriate candidates for psychotherapy. But a few clin

20、icians h ave risen to the challenge and discovered that individual and group psychotherapy is just as effective with the old as with the young. It is easy to understand why an earthquake causes terror. Yet in old age there may b e terror of a very private nature, a sense of disintegration sometimes

21、stemming from inner conflicts, sometimes from a premonition of death or the fear of becoming dependent. Dependency is a grim choice: insecurity and deprivation must be weighed against loss of autonomy and integrity. But if there is nothing shameful about the dependency of a b aby or a young child, t

22、here should be nothing shameful about the dependencies natural wi th old age and diminishing physical resources. The complexity and impersonality of the bureaucratic establishments, which have the means to provide help, are often threatening to old peoplE The younger generation today, on the other h

23、and, will have had many decades to interact with the system by the time they reach old age. Many of us, including healthcare providers, assume that we know what old people an d dying people want, but our assumptions are often a reflections of our won thoughts and feelings based on personal interpret

24、ations of scanty bits of observation. Such assumptions are really an excuse to avoid close contact with the terminally ill. Assuming we know what they want, we observe ourselves from being with them, and sharing their thoughts about the end of life. We sometimes assume, wrongly, that old people are

25、too confused or senile to be awa re of the nearness of death. In consequence, communication between a dying and others is subject to extraordinary omissions and distortions. Protecting the dying from knowledge of their condition often serves to protect us from the uncomfortable prospect of talking a

26、 bout dying and death. Evasions like this only lead to increasing isolation at a time when emotional honesty and understanding are most needed. 23 paragraph 1 24 paragraph 2 25 paragraph 3 26 paragraph 5 A Knowing better how to enjoy life B Freedom in expression C Psychotherapy effective with some o

He smokes cigarettes, s

29、pends long hours in an old laboratory at the US Nation al Institute of Health, and in his free time climbs up cliffs and points his skis down stee p slopes. He also happens to be openly, matter-of-factly gay. What is it that makes Hammer who he is? What, for that matter, accounts for the tal ents an

30、d traits that make up anyones personality? Hammer is not content merely to ask s uch questions。 he is trying to answer them as well. A pioneer in the field of molecular p sychology, Hammer is exploring the role genes play in governing the very core of our in dividuality. To a remarkable extent, his

31、work on what might be called the gay, thrill-seeki ng and quit-smoking genes reflects how own genetic predispositions. That work, which has appeared mostly in scientific journals, has been gathered into a n accessible and quite readable form in Hammers creative new book, Living with Our G enes. “you

32、 have about as much choice in some aspect of your personality.” Hamer and co -author Peter Copeland write in the introductory chapter, “as you do in the shape of your nose or the size of your feet.” Until recently, research into behavioral genetics was dominated by psychiatrists and ps ychologists,

33、who based their most compelling conclusions about the importance of genes o n studies of identical twins. For example, psychologist Michael Bailey of Northwestern Un iversity famously demonstrated that if one identical twin is gay, there is about a 50% like lihood that the other will be too. Seven y

34、ears ago, Hamer picked up where the twin studi es left off, homing in on specific strips of DNA that appear to influence everything from mood to sexual orientation. Hamer switched to behavioral genetics from basic research, after receiving his doctora te from Harvard, he spent more than a decade stu

35、dying the biochemistry of a protein that cells use to metabolize heavy metals like copper and zinc. As he was about to turn 40, however, Hamer suddenly realized he had learned as much about the protein as he cared to. “Frankly, I was bored, ”he remembers, “and ready for something new.” Homosexual be

36、havior, in particular, seemed ripe for exploration because few scientists had dared tackle such an emotionally and politically charged subject. “Im gay,” Hamer s ays with a shrug, “but that was not a major motivation. It was more of a question of int ellectual curiosityand the fact that no one else

37、was doing this sort of research” 31 The first paragraph describes Hamers A looks, hobbies and character. B viewpoint on homosexuality. C unique life-style. D scientific research work. 32 Hamer was a A psychiatrist. B physiologist. C chemist. D biologist. 33 What is Hamer doing now? A He is exploring

38、 the role of genes in deciding ones intelligence. B He is exploring the role of genes in deciding ones personality. C He is writing a book entitled “Live with Our Genes.” D He is trying to answer some questions on a test paper. 34 What happened to Hamers research interest? A He turned to basic resea

39、rch. B He sticked to basic research. C He turned to behavioral genetics. D He sticked to behavioral genetics. 35 According to Hamer, what was one of the main reasons for him to choose homos exual behavior as his research subject? A He is a gay and he wants to cure himself. B He was curious about it

40、as a scientist. C He was curious about it like everyone else. D It is a subject that can lead to political success. 第二篇 Silent and Deadly Transient ischemic attacks(TIAS), or mini-strokes, result from temporary interruptions of blood flow to the brain. Unlike full strokes, they present symptoms last

41、ing anywhere fr om a few seconds to 24 hours. Rarely do they cause permanent neurological damage, but they are often precursors of a major stroke.“Our message is quite clear,” says Dr. Robert Adams, professor of neurology at the Medical College of Georgia in August. “TIAS， while less severe than str

42、okes in the short term, are quite dangerous and need a quick diagnosis and treatment as well as appropriate follow-up to prevent future injury.” Unfortunately, mini-strokes are greatly under diagnosed. A study conducted for the Na tional Stroke Association indicates that 2.5% of all adults aged 18 o

43、r older(about 4.9 milli on people in the U. S. )have experienced a confirmed TI A. An additional 1.2 million A mericans over the age of 45, the study showed, have most likely suffered a mini-stroke w ithout realizing it. These findings suggest that if the public knew how to spot the sympto ms of str

44、oke, especially mini-strokes, and sought prompt medical treatment, thousands of li ves could be saved and major disability could be avoided. The problem is that the symptoms of amini-stroke are often subtle and passing. Non etheless, there are signs you can look out for: *Numbness or weakness in the

45、 face, arm or leg, especially on one side of the body. *Trouble seeing in one or both eyes. *Confusion and difficulty speaking or understanding. *Difficulty walking, dizziness or loss of coordination. *Severe headache with no known cause. Along with these symptoms, researchers have identified some k

46、ey indicators that incre ase your chances of having a full-blown stroke after a TIA: if youre over 60, have exper ienced symptoms lasting longer than 10 minutes, feel weak and have a history of diabete s. As with many diseases, you can help yourself by changing your lifestyle. The first th ings you

47、should do are quit smoking, limit your intake of alcohol to no more than a drin k or two a day and increase your physical activity. Even those who suffer from high blo od pressure or diabetes can improve their oddsand minimize complications if they do ha ve a strokeby keeping their illness under con

48、trol. If you experience any of the symptoms, your first call should be to your doctor. It c ould be the call that saves your life. 36 Which of the following is NOT true of mini-strokes? A The cause of them remains unidentified. B They seldom cause permanent neurological damage. C They symptoms of th

49、em are often passing. D They are not unrelated to major strokes. 37 To prevent mini-strokes from turning into major strokes, it is important to A save thousands of lives. B avoid major disability. C seek prompt medical treatment. D prevent future injury. 38 The passage indicates that the symptoms of

50、 mini-strokes A are always easy to spot. B are frequently hard to recognize. C usually last a couple of days. D can by no means be avoided. 39 All of the following may be signs of mini-strokes EXCEPT for A trouble seeing in one eye. B numbness in the face. C loss of coordination. D severe headache c

51、aused by external injury. 40 It can be inferred from the passage that mini-strokes are A more dangerous than major strokes. B silent and deadly. C difficult to cure. D sure to lead to major strokes. 第三篇 Road Trip Vacations Its summer. In the United States, its the season of swimming pools, barbeques

52、, cam ping and road trips. Road trip vacations where the car journey is part of the fun are especially popular w ith college students, who like to explore the country on wheels. These budget trips are id eal for students who often have plenty of free time but little money. Ever since I went to colle

53、ge, Ive been traveling around a lot, exploring the country, sai d Austin Hawkins, a 19-year-old college student from New York. This summer, Hawkins and his friends have spent weekends traveling in New England. The best part about car trips, said Hawkins, is that you can be spontaneous. On a r oad tr

54、ip, if you get interested in things you see along the way you can stop and explore. Matt Roberts, a 20-year-old student from Ohio who drove to Montreal, Canada, agree s. With road trips you dont have to plan in advance, you can just get into a car and dri ve. Even with high gas prices, driving with

55、friends is cheaper than flying. Roberts paid a bout 40 dollars for gas, but a round trip plane ticket would have cost nearly 400 dollars. Driving trips first became popular in the 1920s. Newly paved roads and improved, ca rs made it possible to travel longer distances. Motels started appearing outsi

56、de cities. By the 1950s, car ownership became the norm. Construction of the US interstate high way system began in 1956 and motel and restaurant chains popped up1 everywhere makin g long distance trips easier. Today, the US has the highest car ownership rate in the world. Only 8 percent of A merican homes have no car, according to the most recent US census. Though many college students dont own a car, most have access to one. On many o f Hawkins trips, they used a borrowed van. Hawkins most memorable road trip t
