20、tMost people have no idea of the hard work and worry that go into the collecting of those fascinating birds and animals that they pay to see in the zoo. One of the questions that is always asked of me is (26) I became an animal collector in the first (27) .The answer is that I have always been inter

21、ested in animals and zoos. According to my parents, the first word I was able to say with any (28) was not the conventional “mamma” or “daddy”, (29) the word “zoo”, which I would (30) over and over again with a shrill (31) until someone, in group to (32) me up, would take me to the zoo. When I(33) a

22、 little older, we lived in Greece and I had a great (34) of pets, ranging from owls to seahorses, and I spent all my spare time (35) the countryside in search of fresh specimens to (36) to my collection of pets. (37) on I went for a year to the City Zoo, as a student (38) , to get experience of the

23、large animals, such as lions, bears, bison and ostriches, (39) were not easy to keep at home. When I left, I (40) had enough money of my own to be able to (41) my first trip and I have been going (42) ever since then. Though a collectors job is not an easy one and is full of (43) , it is certainly a

24、 job which will appeal (44) all those who love animals and (45) .（分数：20.00）A.howB.whereC.whenD.whetherA.regionB.fieldC.placeD.caseA.clarityB.emotionC.sentimentD.affectionA.exceptB.butC.except forD.but forA.reciteB.recognizeC.readD.repeatA.volumeB.noiseC.voiceD.pitchA.closeB.shutC.stopD.comfortA.grew

27、 social scientists. After all, there is no natural reason why 2,500 people should accidentally shoot them- selves each year or why 7,000 should drown or 55,000 die in their cars. No one establishes a quota for each type of death. It just happens that they follow a consistent pattern year after year.

28、A few years ago a Canadian psychologist named Gerald Wilde became interested in this phenomenon. He noticed that mortality rates for violent and accidental deaths throughout the Western world have remained oddly static throughout the whole of the century, despite all the technological advances and i

29、ncreases in safety standards that have happened in that time. Wilde developed an intriguing theory called “risk homeostasis”. According to this theory, people instinctively live with a certain level of risk. When something is made safer, people will get around the measure in some way to reassert the

30、 original level of danger. If, for instance, they are required to wear seat belts, they will feel safer and thus will drive a little faster and a little more recklessly, thereby statistically canceling out the benefits that the seat belt confers. Other studies have shown that where an intersection i

31、s made safer, the accident rate invariably falls there but rises to a compensating level elsewhere along the same stretch of road. It appears, then, that we have an innate need for danger.In all events, it is becoming clearer and clearer to scientists that the factors influencing our lifespan are fa

32、r more subtle and complex than had been previously thought. It now appears that if you wish to live a long life, it isnt simply a matter of adhering to certain pre cautionseating the right foods, not smoking, driving with care. You must also have the right attitude. Scientists at the Duke University

33、 Medical Center made a 15-year study of 500 persons personalities and found, somewhat to their surprise, that people with a suspicious or mistrustful nature die prematurely far more often than people with a sunny disposition. Looking on the bright side, it seems, can add years to your life span.（分数：

34、10.00）(1).What social scientists have long felt puzzled about is why_.（分数：2.00）A.the mortality rate can not be predictedB.the death toll remained stable year after yearC.a quota for each type of death has not come into beingD.people lost their lives every year for this or that reason(2).In his resea

35、rch, Gerald Wilde finds that technological advances and increases in safety standards_（分数：2.00）A.have helped solve the problem of so high death rateB.have oddly accounted for mortality rates in the past centuryC.have reduced mortality rates for violent and accidental deathsD.have achieved no effect

36、in bringing down the number of deaths(3).According to the theory of “risk homeostasis “, some traffic accidents result from_（分数：2.00）A.our innate desire for riskB.our fast and reckless drivingC.our ignorance of seat belt benefitsD.our instinctive interest in speeding(4).By saying “. statistically ca

37、nceling out the benefits that the seat belt confers“ ( Para. 2), the author means_（分数：2.00）A.wearing seat belts does not have any benefits from the statistic point of viewB.deaths from wearing seat belts are the same as those from not wearing themC.deaths from other reasons counterbalance the benefi

38、ts of wearing seat beltsD.wearing seat belts does not necessarily reduce deaths from traffic accidents(5).Which of the following may contribute to a longer life span?（分数：2.00）A.Showing adequate trust instead of suspicion of others.B.Eating the food low in fat and driving with great care.C.Cultivatin

39、g an optimistic personality and never losing heart.D.Looking on the bright side and developing a balanced level of risk.八、Text 2(总题数：1，分数：10.00)We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an indi

40、vidual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided by the genetic markers to link people together into family trees. Pedigrees (家谱) based on such genetic markers can mean a breakthrou

41、gh for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records. There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom

42、many records were never kept in the first place.The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small

43、blood sample. Once the database has enough samples to represent the world genetic make-up, it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or he

44、r family origins through this database.In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships between individuals. “For example, if two men sharing the same last name believe that they are related, but no written record proves th

45、is relationship, we can verify this possibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome(染色体),” explains Ugo APerego, a member of the BYU Molecular Genealogy research team.（分数：10.00）(1).People in a large area may p

46、ossess the same DNA thread because_.（分数：2.00）A.DNA is characteristic of a regionB.they are beyond doubt of common ancestryC.DNA strand has the ability to identify individualsD.their unique identification can be provided via DNA(2).The possible research of family trees is based on the fact that_.（分数：

47、2.00）A.genetics has achieved a breakthroughB.genetic information contained in DNA can be revealed nowC.each individual carries a unique record of who he is and how he is related to othersD.we can use DNA to prove how distant an individual is to a family, a group or a population(3).The Molecular Gene

48、alogy Research Group is building a database for the purpose of_（分数：2.00）A.offering assistance in working out genealogy-related problemsB.solving many issues without relying on traditional written recordsC.providing a pedigree chart of at least four generations in the worldD.confirming the assumption

49、 that all individuals are of the same origin(4).If two men suspected for some reason they have a common ancestor, _.（分数：2.00）A.we can decide according to their family treeB.we can find the truth from their genetic markersC.we can compare the differences in their Y chromosomeD.we can look for written records to prove their relationship(5).Which of the following CANNOT be inferred from the passage?（分数：2.00）A.We are a walking, living, breathing record of our ancestors.B.Many American slaves did not know who their ancestors were
