7、 2部分：阅读判断(总题数：1，分数：7.00)Mad Scientist Stereotype OutdatedDo people still imagine a physicist as a bearded man in glasses or has the image of the mad scientist changed? The Institute of Physics set out to find out whether the stereotype of a physics “boffin“ (科学家) still exists by conducting a survey

8、on shoppers in London. The people were asked to identify the physicist from a photograph of a line-up of possible suspects. 98 percent of those asked got it wrong. The majority of people picked a white male of around 60, wearing glasses and with a white beard. While this stereotype may have been the

9、 image of all average physicist fifty years ago, the reality is now very different since 1960 the number of young women entering physics has doubled and the average age of a physicist is now 31. The stereotype of the absent-minded scientist has lasted a long time because the media and Hollywood help

10、 promote the image of men in white lab coats with glasses sitting by blackboards full of equations (等式) or working with fizzing (嘶嘶响) test tubes. These stereotypes are really damaging to society. Very good school children are put off studying science because they don“t see people like themselves on

11、television or in magazines doing science. They simply don“t relate to the media“s image of the mad scientist. This is one reason why fewer young people are choosing to do science at university. If we want to encourage more young people to study science subjects, we need to change this image of the s

12、cientist and make science careers more attractive. But we must also develop children“s interest in science. In an attempt to change this negative image, an increasing number of science festivals are being organized. Thousands of people from secondary schools are also encouraged to take part in the i

13、nternational wide science competitions of which the most popular are the national Science Olympiads. Winning national teams then get the opportunity to take part in the International Science Olympiads which are held in a different country every year. These events are all interesting for the young pe

14、ople who take part but they only involve a small proportion of students who are already interested in science. It seems that there is a long way to go before science becomes attractive as subjects like computer studies or fashion and design.（分数：7.00）(1).Most people have similar ideas of what a physi

To describe a baby“s growth, the old saying “one thing leads to another“ should really read, “one thing leads to an explosion

18、.“ The perfection of vision and the ability to hold his head up allow appreciation of visual space. The evolution of increasingly efficient reaching also lets the baby appreciate and participate in his three-dimensional world. 2. You may notice that your baby can grab toys with either hand. This is

19、partly because the baby has learned to grasp an object even if it touches his hand lightly or his eyes are averted. By the end of the fourth month, he can probably alternate hands to grab the toys or transfer a toy from one hand to the other. He may even wave it briskly, then transfer it and repeat

20、the waving, shuttling it back and forth between hands. In imitating the behavior of one hand with the other, the baby may be becoming aware that he can do the same thing with each arm and that each hand is distinct from the other. This awareness is important to his receiving information about space.

21、 The baby also begins to see himself act when he repeatedly reaches for and grasps things. He starts to distinguish himself from the outer world. 3. If you would like another sign of this growth process, try one of Gesell“s measures of mental growth, the behavior of a baby before a mirror. According

22、 to Gesell, a baby will smile at his image at around twenty weeks of age. Hold your baby up to a mirror and watch him examine the faces there. He will probably attend most to his own image and perhaps smile at it. As his image returns the smile, he may become active and vocalize. He may also look ba

23、ck and forth between your image and you as if the duplication puzzles him. A baby who knows his mother“s face cannot understand two of them. Calling softly to your baby, as he looks at your confusing double, complicates matters even further. His turning back to the real you shows that a baby four mo

24、nths old is likely to have the ability of preference in discrimination. 4. An early attachment to one objecta toy or a stuffed animalis another index of discrimination, as well as self-development, for the baby“s interests are going beyond himself. Most babies do not prefer one toy this early, but s

25、ome will. After exploring each toy, your baby may start reaching and playing with one special one. In the months to come, the toy or anything else the baby identifies with himself by wearing or carrying may become a “lovely“. A “lovely“ will be slept with, chewed, hugged, loved, and “talked to“. The

26、se “lovelies“ give the baby a way of coping with the necessary separations from the mother. A friendly and familiar toy bear may just make him easier on himself. Rather than feeling threatened, a mother should be flattered by her baby“s extension of affection elsewhere. A baby with the heart to find

Having a quick “pick-me-up“ cup of coffee late in the day will play havoc with your sleep. As well as being a stimulant, caffeine

31、interrupts the flow of melatonin, the brain hormone that sends people into a sleep. Melatonin levels normally start to rise about two hours before bedtime. Levels then peak between 2 am and 4 am, before falling again. “It“s the neurohormone that controls our sleep and tells our body when to sleep an

32、d when to wake,“ says Maurice Ohayon of the Stanford Sleep Epidemiology Research Center at Stanford University in California. But researchers in Israel have found that caffeinated coffee halves the body“s levels of this sleep hormone. Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv Un

33、iversity found that six volunteers slept less well after a cup of caffeinated coffee than after drinking the same amount of decal. On average, subjects slept 336 minutes per night after drinking caffeinated coffee, compared with 415 minutes after decal. They also took half an hour to drop off twice

34、as long as usualand jigged around in bed twice as much. In the second phase of the experiment, the researchers woke the volunteers every three hours and asked them to give a urine sample. Shilo measured concentrations of a breakdown product of melatonin. The results suggest that melatonin concentrat

35、ions in caffeine drinkers were half those in decaf drinkers. In a paper accepted for publication in Sleep Medicine, the researchers suggest that caffeine blocks production of the enzyme that drives melatonin production. Because it can take many hours to eliminate caffeine from the body, Ohayon recom

36、mends that coffee lovers switch to decaf after lunch.（分数：15.00）(1).The author mentions “pick-me-up“ to indicate that _.（分数：3.00）A.melatonin levels need to be raisedB.neurohormone can wake us upC.coffee is a stimulantD.decaf is a caffeinated coffee(2).Which of the following tells us how caffeine affe

37、cts sleep?（分数：3.00）A.Caffeine blocks production of the enzyme that stops melatonin production.B.Caffeine interrupts the flow of the hormone that prevents people from sleeping.C.Caffeine halves the body“s levels of sleep hormone.D.Caffeine stays in the body for many hours.(3).What does Paragraph 3 ma

40、assage probably agrees that _.（分数：3.00）A.coffee lovers sleep less than those who do not drink coffeeB.we should not drink coffee after supperC.people sleep more soundly at midnight than at 3 amD.if we feel sleepy at night, we should go to bed immediately六、第二篇(总题数：1，分数：15.00)Can Buildings Be Designed

41、 to Resist Terrorist AttackIn the aftermath of the terrorist attack on the World Trade Center, structural engineers are trying hard to solve a question that a month ago would have been completely unthinkable: Can building be designed to withstand catastrophic blasts inflicted by terrorists? Ten days

42、 after the terrorist attacks on the twin towers, structural engineers from the University at Buffalo and the Multidisciplinary Center for Earthquake Engineering Research (MCEER) headquartered at UB traveled to ground zero as part of a project funded by the National Science Foundation. Visiting the s

43、ite as part of an MCEER reconnaissance visit, they spent two days beginning the task of formulating ideas about how to design such structures and searching for clues on how to do so in buildings that were damaged, but still are standing. “Our objective in visiting ground zero was to go and look at t

44、he buildings surrounding the World Trade Center, those buildings that are still standing, but that sustained damage,“ said M. Bruneau, Ph.D. “Our immediate hope is that we can develop a better understanding as to why those buildings remain standing, while our long-term goal is to see whether earthqu

45、ake engineering technologies can be married to existing technologies to achieve enhanced performance of buildings in the event of terrorist attacks,“ he added. Photographs taken by the investigators demonstrate in startling detail the monumental damage inflicted on the World Trade Center towers and

46、buildings in the vicinity. One building a block away from the towers remains standing, but was badly damaged. “This building is many meters away from the World Trade Center and yet we see a column there that used to be part of that building“, explained A. Whittaker, Ph. D. “The column became a missi

47、le that shot across the road, through the window and through the floor.“ The visit to the area also revealed some surprises, according to the engineers. For example, the floor framing systems in one of the adjacent buildings were quite rugged, allowing floors that were pierced by tons of falling deb

48、ris to remain intact.“ Highly redundant ductile framing systems may provide a simple, but robust strategy for blast resistance,“ he added. Other strategies may include providing alternate paths for gravity loads in the event that a load-bearing column fails.“ We also need a better understanding of t

49、he mechanism of collapse, “said A. Whittaker. “We need to find out what causes a building to collapse and how you can predict it.“ A. Reinhorn, Ph.D. noted that “earthquake shaking has led to the collapse of many buildings in the past. It induces dynamic response and extremely high stresses and deformations in structural components. Solutions developed for earthquake-resistant design may be directly applicable to blast engineering and terrorist-resistant design. Part of our mission now at UB is to transfer these solutions and to develop new ones where none exist at present. “（分数：
