Many patients died after even the smallest operations. This was because bacteria entered the cuts in the patients“ bo

12、died and started infection . In some countries, up to 90 percent of patients died from infection after operations. In 1865, however, Joseph Lister, a British surgeon, found an answer to the problem. He used an “antiseptic“ during and after operations. This killed the dangerous bacteria and most of h

13、is patients lived. Since then, surgeons have used antiseptics in all operations. Surgery has developed in many important ways since the day of Joseph Lister. Today, when patients go to hospital for an operation, they can expect the best treatment, in clean and hygienic conditions.（分数：10.00）(1).Opera

17、year I purchased a game for my boys and I played it with them. The trouble was that everyone won the game. We all arrived at the end together. This seems great in theory, but where“s the incentive (刺激) to keep playing? We played the game twice, and it has been there gathering dust ever since. Withou

18、t a potential winner, a game or contest loses its excitement. If there“s nothing to compete for, the drive to do one“s best is replaced by a “What“s the point“ attitude. Competition is closely related to motivation (动力). It“s part of human nature to be competitive; after all, survival of the fittest

19、 is the basis of evolution . A competitive spirit is the key to our success as adults, so why shouldn“t we cultivate it in our children? I“m not suggesting we set our children against each other in heated competitions in all aspects of life. We should guard against coaches who lose the spirit of goo

20、d sportsmanship (运动员风格) in the heat of the game. But in the right situations, a healthy competition can teach our kids a lot about life. While games and contests illustrate the importance of drive and determination, they also teach our children how to lose. And with that comes other good lessons - a

21、bout learning from mistakes, searching for ways to improve and finding the will to try again.（分数：10.00）(1).We can learn from the first paragraph that the game bought by the author（分数：2.00）A.proved to be unchallengingB.gathered dust very easilyC.caused trouble for childrenD.was played with lots of fu

23、B.loveC.abilityD.spirit(4).According to the author, in a game or contest children should be encouraged _.（分数：2.00）A.to obey their coaches strictlyB.to compete in all aspects of lifeC.to develop a competitive spiritD.to compete for nothing but a prize(5).What is important for a loser in the game?（分数：

24、2.00）A.Competition.B.Self-determination.C.Survival.D.Self-improvement.五、Passage There(总题数：1，分数：10.00)Shortly after Charles Darwin published his theory of evolution, a lady was asked what she thought of the idea that humans and animals came down from a common ancestor (祖先). “Let us hope it is not tru

25、e,“ she said. “And, if it is true, let us hope it does not become public knowledge.“ This story is probably untrue, but it illustrates well the attitudes of the time. Today, we are more comfortable with our past. Many people accept Darwin“s view of how we came into being - that our bodies“ evolved t

26、hrough the process of natural selection acting on our genes. However, Darwin believed evolution was responsible for far more than just our physical characteristics. He saw it as the major influence in shaping our psychology. Indeed, he predicted that “in the distant future, psychology will be based

27、on a new foundation.“ This foundation was, of course, his theory of evolution. To those in favor of concepts like free will and personal responsibility, such an idea seems quite stupid. But a growing number of scientists are questioning the extent to which our behavior is controlled by our culture .

28、 Their research has revealed increasing evidence that the human mind is made up of natural mechanisms, which control everything from the way we perceive (感知) time and space, to how we learn survival techniques and choose mates.（分数：10.00）(1).The story about the lady suggests that, in Darwin“s time, t

29、he theory of evolution made many people feel _.（分数：2.00）A.embarrassedB.delightedC.comfortableD.miserable(2).Which of the following statements is TRUE according to Paragraph 2?（分数：2.00）A.People“s attitudes towards Darwin“s view remain unchanged.B.Darwin“s view of man“s origin has been widely accepted

30、.C.Natural selection has no effect on our genes.D.The story about the lady has proved to be true.(3).The phrase “was responsible for“ in Line 1, Paragraph 3 most probably means“_“.（分数：2.00）A.had the ability to influenceB.had the duty ofC.was to blame forD.was the cause of(4).According to Darwin“s vi

31、ew, our psychology _.（分数：2.00）A.will change greatly in the futureB.has nothing to do with evolutionC.is mainly shaped by evolutionD.is shaped by our physical characteristics(5).If Darwin“s view on our psychology is correct, what controls our behavior?（分数：2.00）A.The characteristics of our culture.B.T

32、he mechanisms of our mind.C.The way we perceive time and space.D.The way we live and choose mates.六、Passage Four(总题数：1，分数：10.00)Nonverbal (非语言的) communication has to do with gestures, movements and closeness of two people when they are talking. The scientists say that those gestures, movements and s

33、o on have meaning which words do not carry. For example, the body distance between two speakers can be important. North Americans often complain that South Americans are unfriendly because they tend to stand close to the North American when speaking, while the South American often considers the Nort

34、h American to be “cold“ or “distant“ because he keeps a greater distance between himself and the person he is speaking to. The “eye contact“ provides another example of what we are calling nonverbal communication. Scientists have observed that there is more eye contact between people who like each o

35、ther than there is between people who don“t like each other. The length of time that the person whom you are speaking to looks at your eyes indicates the amount of interest he has in the things you are talking about . On the other hand, too long a gaze can make people uncomfortable. The eyes apparen

36、tly play a great part in nonverbal communication. Genuine warmth or interest, shyness or confidence can often be seen in the eyes. We do not always consider a smile to be a sign of friendliness. Someone who is always smiling, and with little apparent reasons, often makes us uneasy.（分数：10.00）(1).Acco

37、rding to the passage, nonverbal communication _.（分数：2.00）A.is a method often used by people who cannot speakB.can tell something that words cannotC.can be used to talk with people who cannot bearD.is less used than words(2).The South American _.（分数：2.00）A.tends to keep a distance between himself and

38、 the person he is speaking toB.usually stands close to the person he is talking toC.is often unfriendly when spoken toD.is often cold and distant when speaking(3).Which of the following is NOT true?（分数：2.00）A.Less eye contact suggests distance in relation.B.the longer one looks at you, the more inte

39、rest he has in you.C.there is more eye contact between people who like each other.D.Shorter eye contact shows more interest in what one is talking about(4).Too long a gaze _.（分数：2.00）A.may upset people being looked atB.shows one“s great confidenceC.indicates one“s interest in the talkD.tells you how
