1、2005年福建醫(yī)大考博英語(yǔ)真題Part I. Reading Comprehension (40%)Directions: Read the following five passages. Answer the questions below each passage by choosing A, B, C or D. Mark your answer on ANSWER SHEET. Passage OneMost American women know regular Pap smears cut the risk of cervical cancer, but that doesnt

2、mean they go in to get the test. Half the women who develop the disease havent had a Pap test for three years. But a new test may one day offer a userfriendlier alternative. Two studies in last weeks Journal of the American Medical Association report that a DNA test detects cervical cancer just as w

3、ell as Pap smears do. Better yet, women can collect samples for the test themselves. The Pap smear has caused a fivefold drop in cervical cancer since 1960s. But since a doctor must take the smear during a pelvic exam, women who dont have access to gynecologists arent screened. So a self-collected t

4、est could be good news for patients, like the 1,365 South Africans in one of the JAMA studies. They collected their own vaginal samples on swabs. Samples were sent to the United States, where a DNA test caught 66 percent of the womens cervical cancers; 68 percent were detected by Pap smears. And whe

5、n doctors collected the samples, that study, and a second one of Costa Rican women, found that DNA tests actually caught more cancers than Pap smears.Does this mean women can bid farewell to the Pap test? Probably not. Doctors think cervical cancer is caused by the transmitted human papilloma virus.

6、 The DNA test detects genetic material from 13 forms of it, which are found in 96 percents who have cervical cancer. But most young women who have papilloma virus dont actually develop cancer. So the test can cause false alarms. DNA tests could prove useful for older women, though. Most women fight

7、off the virus before they turn 40. If they dont, theyre more likely to get cervical cancer. But theyre also less likely to get Pap smears because many stop visiting gynecologists after childbearing age, and the test gets more uncomfortable. So a quick, self-collected test could cut cervical cancer r

8、ates: “If we could make screening as easy as a urine test at the doctors office, we would get more coverage,” says Thomas Wright, lead author of the South African study and associate professor of Pathology at Columbia. Though true home testing awaits FDA approval and could be years away, general pra

9、ctitioners could administer the test, too.Detection is one thing; treating cervical cancer is another. Doctors recently announced that a combination of radiation and chemotherapy can cut the risk of death 30 to 50 percent. And researchers hope to someday prevent papilloma infections: “Ultimately, va

10、ccines will be the best way we prevent cervical cancer worldwide,” Wright predicts. But for now, the DNA test could help mainly in countries that can afford the $6 billion the United States spends on Pap screening every year. But theres one important caveat: a new test will be useful only if patient

11、s can get medical treatment afterward.1. The Pap smear _.A) has caused a fivefold drop in cervical cancer since the 1960sB) caught 66 percent of the womens cervical cancersC) Caught more cancers than the DNA TestD) Is very convenient for women to do self-examination2. Why the DNA test cannot replace

12、 Pap smear?A) Doctors think cervical cancer is caused by the sexually transmitted human papilloma virus.B) The DNA test detects genetic material from 12 forms of papillooma virus, which are found in 96 percent of patients who have cervical cancer.C) Most young women who have papilloma virus dont act

13、ually develop cancer.D) The DNA test can cause false alarms.3. Which of the following statement is not correct?A) Home DNA test has not yet been approved by DNA.B) DNA tests could prove useful for older women. Most women fight off the virus before they turn 40.C) Doctors recently announced that a co

14、mbination of radiation and chemotherapy can cure cervical cancer.D) The DNA test could help mainly in countries that cant afford the $6 billion the United States spends on Pap screening every year.Passage TwoAlthough language is used to transmit information, the informative functions of language are

15、 fused with older and deeper functions so that only a small portion of our everyday speech can be described as purely informative. The ability to use language for strictly informative purposes was probably developed relatively late in the course of linguistic evolution. Long before that time, our an

16、cestral species probably made the sorts of cries animals do to express feelings of hunger, fear, loneliness, and the like. Gradually these noises seem to have become more differentiated, transforming the cries into language as we know it today.Although we have developed language in which accurate re

17、ports may be given, we still use language as vocal equivalents of gestures such as crying in pain. When words are used as the vocal equivalent of expressive gestures, language is functioning in pre-symbolic ways. These pre-symbolic uses of language coexist with our symbolic system, so that the talki

18、ng we do in everyday life is a thorough blending of symbolic and pre-symbolic language.What we call social conversation is mainly pre-symbolic in character. When we are at a large social gathering, for example, we all have to talk. It is typical of these conversations that, except among very good fr

19、iends, few of the remarks made have any informative value. We talk together about nothing at all and thereby establish a relationship.There is a principle at work in the selection of the subject matter we deem appropriate for social conversation. Since the purpose of this kind of talk is the establi

20、shment of communion, we are careful to select subjects about which agreement is immediately possible. With each new agreement, no matter how commonplace, the fear and suspicion of the stranger wear away, and the possibility of friendship emerges. When further conversation reveals that we have friend

21、s or political views orartistic values or hobbies in common, a friend is made, and genuine communication and cooperation can begin.4. The author uses the term “pre-symbolic language” to mean _.A) language used between friendsB) language that lacks an elaborate grammatical structureC) nonverbal expre

22、ssions used in communicatingD) language that does not convey specific information5. The primary value of pre-symbolic language for humans is that it _.A) Is common to all languages rather than unique to any one languageB) Permits and aids the smooth functioning of interpersonal relationshipsC) Helps

23、 us understand and express our emotionsD) Allows for a desirable amount of social mobility6. The most crucial difference between pre-symbolic and symbolic language lies in the _.A) origin and developmental path of each mode in linguistic evolutionB) degree to which each mode may be accompanied by ex

24、pressive gesturesC) purposes served by each modeD) clarity each mode makes possiblePassage ThreeIn the ultrasound clinic, Suzie Woods stared at the screen in front of her. The sonographer pressed the foetal probe over her abdomen, already stretched into a taught little mound by months of pregnancy.

25、“There are two embryos on the screen,” he told her. “No, no, there should only be one,” Suzie insisted, her eyes now fixed intently on his. “Look, Ill show you,” he said. “There are two hearts beating on the screen.” “That moment,” recalls Suzie, “would have to have been the most electric of my life

26、. I was absolutely ecstatic that these two gorgeous little people were all mine. “Suzie and the twinsSimon and Sabrina, now seven monthsare part of an international population explosion, a twin boom in Western developed societies.Reluctant to interrupt satisfying careers, women are having babies lat

27、er in life and increasingly using fertility treatments. These two factors mean Australian mothers are having more twins than ever before. In 1998, 3,592 sets of twins were born in Australia, a 25 percent increase on the figure of 2,871 just 10 years earlier. This is despite static figures for the to

28、tal number of births in 1988 and 1998. And the trend to multiple births shows no sign of abating. King George V hospital in the inner Sydney suburb of Camperdown, for instance, has just beaten its own record: 68 twins were born in the past six monthsan increase of 40 percent on the previous six mont

29、hs, says the director of obstetrics, Dr. Andrew Child. Overseas, the number of twins born in the United States has doubled since 1980 and a similar, though more moderate, trend is evident in Britain, where twins as a proportion of all births are up a third since 1982.A twin industry has been spawned

30、, especially in the U.S., where you can now have your baby delivered by a specialist twin obstetrician and looked after by specialist nannies. There are 10 US magazine title aimed at the parents of twins and at least three dozen books, along with twin strollers ans a whole range of other specialized

31、 goods. In Australia, there is a new acceptance of the problems confronting the parents of twins, and mothers of twins leaving hospital have access to an ever-widening circle of support and services. The NSW Multiple Birth Association has mushroomed from one support group of three mothers to 34 club

32、s across the State in just 10 years.Most are bristling with activity, regularly sending newsletters and social calendars to parents, holding information evenings and support groups, and offering hotlines, a library service and even advice on what brand of twin stroller mothers should buy. More impor

33、tantly, these groups are as generous with camaraderie as practical advice. “Often it was quicker to ring the Multiple Birth Association than look up the baby manual,” says Suzie, who soon discovered that the euphoria at having twins was followed by a whole caravan of complications after they arrived

34、.7. Why the Australian mothers are having more chances to have twins than ever before?A) Career women do not want to have babies early because they enjoy satisfying professions or they have to work for a living.B) Australian women are born to have genetic capabilities to bear twins.C) Australian wom

35、en are strong and fertile comparatively.D) Australian women prefer to use fertilizer in pregnancy.8. The author mentioned Suzie Woods at the beginning of the article to _.A) make his article sound catchyB) express how ecstatic Suzie was when she knew she had two embryosC) portray the following topic

36、 of the articleD) condemn the twin boost in the western countries9. What is the fact of Australias twin boom, according to the passage?A) In 1998, 3,592 sets of twins were born in Australia, a 25 percent increase on the figure of 2,871 just 10 years earlier.B) The trend to multiple births shows no s

37、ign of declining.C) 68 twins were born in the past six-months in King George V Hospital in the inner Sydney suburb of Camperdown, which is an increase of 40 percent on the previous six months.D) All of the above.10. Which of the following statement is NOT true about U.S. according to the passage?A)

38、There are many magazines and books aimed at the parents of twins in U.S.B) There is a new acceptance of the problems confronting the parents of twins, and mothers of twins leaving hospital have access to an ever-widening circle of support and services.C) Parents can have their babies delivered by a

39、specialist twin obstetrician and looked after by specialist nannies.D) The number of twins born in the United States has doubled since 1980.Passage FourUntil recently doctors were taught that the human body lives in homeostasis, changing little during the day. The science of chronobiologythe study o

40、f how time affects lifeis sparking a medical revolution by revealing how much our bodies change through circadian (daily) rhythms.These natural biological rhythms are as vital as our heart beat. By learning their secrets, we are discovering new ways to prevent and cure illness. There isnt a function

41、 in your body that doesnt have its own rhythm.While you sleep, your blood pressure falls, our temperature drops more than a degree from its daily afternoon high, and some blood pools in your bodys extremities. Come morning, the body has to “jump start” itself from its sleeping to waking stages with

42、a surge of excitation chemicals calls catecholamines. Heart rate increases and blood vessels constrict, raising blood pressure and reducing blood flow to heart muscle; this might cause ischemia, or angina, as well as sudden death from myocardial infarction. If hardened plaques of cholesterol coat ar

43、teries, fragments may break loose, causing the clots that lead to heart attacks.When a leap from bed and a surge of catecholamines combine to “get your blood moving”, your blood is near its daily peak in thickness and tendency to clot. Packing kids off to school and rushing to get ready for work add

44、 emotional tension to the physical stress.This circadian cardiovascular risk comes not from your bedside clock but from your interior biological clock. Whatever hour you get up, your peak risk of myocardial infarction will come within two to three hours after awakening.The master timekeepers in our

45、bodies help synchronize us with such outside cycles as day and night. Like orchestra conductors, they coordinate hundreds of functions inside us. Our body dances through the day to complex inner rhythms of rising and falling tides of hormones, immune cells, electrolytes and amino acids.Most people e

46、njoy a peak in short-term memory and mental quickness in the late-morning hours until shortly afternoon. Then a measurable dip in energy and efficiency begins around 1 p.m. In some Mediterranean cultures, shops close during the afternoon for a period of siesta.In the afternoon, exercise endurance, r

47、eaction time and manual dexterity are at their highest. Some research indicates that from then until early evening, athletes put in their best performances. From 6:30 p.m. until 8:30 p.m. is the sharpest time of day for long-term memory, an optimal time to study.Our daily rhythms can bring a dark si

48、de to the evening, however. These hours include a second daily peak in heart attacks, although smaller than the mornings. Around 7 p.m., alcohol takes longer to be cleared by your liver, and hence can be more intoxicating and performance-impairing than at other times of dayexcept 11 p.m. which bring

49、s a second peak of high ethanol susceptibility.Students often cram during late-night and early-morning hours. Research, however, shows this is the time of the circadian cycle when long-term memory, comprehension and learning are at their worst.Sensitivity to pain has generally increased throughout t

50、he day; it reaches its peak late at night. But by early morning the body may have doubled its night time levels of beta endorphins, which help relieve pain. Researchers theorize that this is what increases the bodys pain tolerance during the hours after awakening.For most of us, sleep is a time of l

51、ife renewal. Within the first 90 minutes or so of sleep, we reach our daily peak of growth hormone, which may help regenerate our bodies.By understanding our body clocks, we can improve our health and continue to foster our survival. Without grasping, for instance, that our natural temperature rises

52、 one to two degrees from morning until evening, we could misjudge thermometer readings, A temperature of 99 degrees might signal perfect health at 5 p.m. but augur illness at 7 a.m.The effects of drugs are also subject to our rhythms. For instance, many doctors are learning to give powerful cancer d

53、rugs with the patients biological clocks in mind. A given chemotherapy drug may be highly toxic to the kidneys at one time of day, for example, and far less harmful at another.By turning the cycles of your biological clock in your favor, you may reduce your daily danger and increase your days of lif

54、e.11. No matter what hours you get up, sudden rise from bed _.A) brings energy to ones morning workB) should help form a good habitC) may cause heat attacksD) increases heart rate to normal action12. The passage advises that to improve our health, it is essential to _.A) avoid sitting up lateB) do t

55、he right thing at the right timeC) get up as soon as the bedside clock gives alarmD) understand our body clock13. In the authors opinion, physical stress should be avoided _.A) as soon as you awakeB) two to three hours after awakeningC) around 1 p.m.D) in the late evening14. If you want to take some

56、 pills to kill your pain, youd better take them _.A) after lunchB) before going to bedC) in the early morningD) late at night15. According to the passage, it is harmful to _.A) do morning exercise at about 6 oclockB) neglect the doctors advice about the time to take drugsC) go to sleep again after a

57、wakeningD) do memory work in the late-morning hoursPassage FiveAs a person now publicly identified with the movement to reform our drug laws through the use of some form of decriminalization, I consider it very important to say that I am not soft on either drug use or drug dealers. Im a soldier in t

58、he war against drugs. I spent years prosecuting and jailing drug dealers, and had one of the highest rates of imprisonment for drug convictions in the country. And if I were still States Attorney, I would be enforcing the law as vigorously as ever. My experience as a prosecutor did not in any way alter my passionate dislike for drug dealers, it simply convinced me that the present sys
