If Stephen Hawking lives until the year 2017, he will have lived more than 50 years longer than his doctors expected. When he was a college student, doctors discovered that he had a rare disease. This disease causes a gradual disintegration (分解) of the nerve cells in the brain cells that regulate voluntary muscle activity. Death almost always occurs within two or three years. Today Stephen Hawking cannot walk or speak. He cannot move his arms or his head. He cannot taste or smell anything. And yet this man is Professor of Mathematics at Cambridge University, a position held by the famous scientist Isaac Newton in 1669. Hawking is often described as the greatest scientist since Albert Einstein, but to the world outside science, he is also known as the man who made scientific theory understandable. His book, A Brief History of Time, has sold over eight million copies. He says that since he does not have to think about his body or do any of the things other men have to worry about, such as washing the car or working in the yard, he can dedicate all of his time to thinking. This puts him in the perfect position to find the answer to the question that he has dedicated his life to. His question is: Is there a complete theory of the universe and everything in it? Despite his tremendous physical disabilities, he has already made some very important discoveries about the origin of the universe, how the universe holds together, and how it will probably end. He has also been able to explain the secrets of "black holes" in space. Now he is looking for a set of rules that everything in our universe must obey. He calls it the Theory of Everything: He thinks that someone will have found the answer within the next 20 years. If Stephen Hawking is able to find his Theory of Everything, he will have given the world the opportunity to understand things that will change the whole nature of science and probably also the way we live.

1 Since heat naturally moves from hotter regions to cooler ones, the heat from the earth's center flows outwards towards the surface. In this way, it transfers to the next layer of rock. If the temperature is high enough, some of this rock melts and forms magma (岩浆). The magma ascends in its turn towards the earth's surface. It often remains well below the earth's surface, creating vast areas of hot rock. In such regions, there are deep cracks, which allow rainwater to descend underground. Some of the heated rainwater travels back up to the earth's surface where it will appear as a hot spring. However, if this ascending hot water reaches a layer of impermeable (不可渗透的) rock, it remains trapped, forming a geothermal reservoir. If geothermal reservoirs are close enough to the surface, they can be reached by drilling wells. Hot water and steam shoot up the wells naturally, and can be used to produce electricity in geothermal power plants. 2 A few geothermal power plants depend on dry-steam reservoirs which produce steam but little or no water. In these cases, the steam is piped up directly to provide the power to spin a turbine generator. The first geothermal power plant, constructed at Lardarello in Italy, was of this type, and is still producing electricity today. 3 Most currently operating geothermal power plants are either "flash" steam plants or binary (双重的) plants. Flash plants produce mainly hot water ranging in temperature from 300° to 700° Fahrenheit. This water is passed through one or two separators where, released from the pressure of the underground reservoir, it "flashes" or boils into steam. Again, the force of this steam provides the energy to spin the turbine and produce electricity. The geothermal water and steam are then reinjected directly back down into the earth to maintain the volume and pressure of the reservoir. Gradually they will be reheated and can then be used again. 4 A reservoir with temperatures below 300° Fahrenheit is not hot enough to flash steam but it can still be used to generate electricity in a binary fluid. The steam from this is used to power the turbines. As in the flash steam plant, the geothermal water is recycled back into the reservoir.
1. Paragraph 1 ______ A. Dry steam plants B. Binary plants C. Origin of geothermal energy D. Generation of electricity E. Flash steam plants F. Recyclable water and steam
5. A geothermal reservoir is formed when hot water is trapped under ______. A. the energy to turn a turbine B. impermeable rock C. one or two separators D. turbine operator E. little or no water F. hot springs
B
[解析] 本句意思：当热水被困于______之下时会形成地热储层。根据第一段倒数第三句“if this ascending hot water reaches a layer of impermeable rock, it remains trapped, forming a geothermal reservoir”可知，热水被困于不可渗透的岩石层下时会形成地热储层，故本题选B。
6. A dry-steam reservoir produces steam with ______.
E
[解析] 本句意思：干蒸汽储层产出蒸汽______。根据第二段第一句“A few geothermal power plants depend on dry-steam reservoirs which produce steam but little or no water.”可知，一些地热干蒸汽发电站产出蒸汽时有少量或没有水，故本题选E。
7. Flash plants produce hot water through ______.
C
[解析] 本句意思：地热闪发蒸汽发电站通过______产出热水。由第三段第三句“This water is passed through one or two separators where, released from the pressure of the underground reservoir.”可知，水是通过一或两个分离器才形成的蒸汽，故本题选C。
8. In a binary plant, the heat of the geothermal water can be converted into ______.
A
[解析] 本句意思：在双循环发电站，地热水源的热量可以被转化成______。由此可定位到最后一段。在二元流体发电时，“The steam from this is used to power the turbines”，即产生的蒸汽可驱动涡轮机。对应选项A中的the energy to turn a turbine(驱动涡轮机的能量)，故本题选A。
第4部分：阅读理解 下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。
第一篇
Smart Windows
Windows not only let light in to cut down on electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with an advanced technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between easily. "It took us a long time to figure out what a window really is," says Claes Granqvist. He's a professor of solid-state physics at Uppsala University in Sweden. "It's contact with the outside world. You have to have visual contact with the surrounding world to feel well." So, windows and natural light are important for improving the way people feel when they're stuck indoors. Yet, windows are the weak link in a building when it comes to energy and temperature control. In winter, cold air leaks in. When it's hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing (使人清新的), actually sucks up enormous amounts of electricity in buildings around the world. Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing (用玻璃覆盖), and layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic (发色的) technologies which involve changes of color. Electrochromic (电致色的) windows use electricity to change color. For example, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide (氧化钨) works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage (电压) is decreased, the window darkens until it's completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark. One important feature that makes a smart window so smart is that it has a sort of "memory". All it takes is a small change of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer be needed. "In the future," Granqvist says, "our buildings may look different."
1. Which of the following values of windows is NOT mentioned?
A.They let light in to brighten the house.
B.They let light in to heat the house.
C.They let us have visual contact with the surrounding world.
D.They let us think about the outside world.
A B C D
D
[解析] 事实细节题。与窗户作用有关的内容位于文章的第一、二段。根据第一段“Windows not only let light in to cut down on electricity use for lighting, but the light coming through the window also provides heat.”可知，窗户可以让光线进入室内并提供热量，故A、B正确。第二段中Claes所说的话“It's contact with the outside world. You have to have visual contact with the surrounding world to feel well”说明了窗户的另一个作用就是让人们能看到外界的事物，故C叙述正确。文章唯独没有提到D。
2. The expression "when it comes to" in Paragraph 3 is used to ______.
A.signal the arrival of a guest
B.indicate the recovery of consciousness
C.show our understanding of something
D.introduce a new aspect of a topic
A B C D
D
[解析] 词义猜测题。文章第三段主要说的是窗户的弱点，即冬天冷空气会透过窗户进来，夏天阳光照进来又会太热。这样一来人们就会开空调调节室温，但是这很费电。“when it comes to”本意是“当提到……时”，用于引入一个新话题或新角度。上文主要在说窗户的功能，但是一谈到能量与温度调节，窗户就是建筑中的薄弱环节，故D正确。
3. According to Paragraph 4, smart windows are the windows that ______.
A.are coated
B.are glazed
C.have several layers
D.can change color
A B C D
D
[解析] 事实细节题。文章第四段的主要内容是科学家对通过窗户来达到节能的效果进行了长时间的研究。根据“Smart windows go a step further. They use chromogenic technologies which involve changes of color.”可知，智能窗户在镀层窗户、覆盖窗户等的基础上更进一步，运用了发色技术，其中就包含了变色这一功能，故选择D。前三项都是之前科学家们对普通窗户进行的改造，并不属于智能窗户的范畴。
4. Which paragraph gives an account of the way electrochromic windows change color?
[解析] 事实细节题。根据文章第六段第一句话“One important feature that makes a smart window so smart is that it has a sort of 'memory'.”可知，智能窗户的独特之处、智能之处在于其具有记忆功能，通过改变或保持某种状态来减少空调的使用频率，也许未来也就不再需要空调了。故选D。
第二篇
Sports Star Yao Ming
If Yao Ming is not the biggest sports star in the world, he is almost certainly the tallest. At 2.26m, he is the tallest player in the National Basketball Association (NBA) and holds the record as the most towering Olympian ever to compete in the Gaines. But what really stands out about the giant center is his celebrity (名气). Few, if any, Chinese athletes are as well-known as Yao around the world. People across the globe are fascinated with Yao, not only for his basketball prowess (杰出的才能) but also for being a symbol of international commerce. When Yao joined the Houston Rockets as the No. 1 pick in the 2002 NBA draft (选拔), he was the first international player ever to be selected first. His assets on the court are clear enough—no NBA player of his size has ever possessed his mobility, so he is a handful (难对付的人) for opponents on either end of the court. But what makes Yao invaluable to the Rockets organization is his role as a global citizen and as a bridge to millions of potential basketball fans in China. When it was announced in February that Yao would miss the rest of the NBA season and possibly the Olympics with a stress fracture (骨折) in his left foot, a collective shudder (震动) spread across China. After considerable debate and discussion, Yao opted to get his foot surgically treated in an operation that placed several tiny screws across the bone, to offer his overburdened foot more support. The surgery was a success, and though the estimated four-month recovery period will leave him little time to prepare with Team China, Yao has vowed to be ready for the Beijing Olympics. Yao wrapped up a 10-day trip to China, where he underwent a series of traditional Chinese medicine (TCM) treatments, hoping to accelerate his recovery process. Western experts are generally skeptical of TCM's benefits, although new research from the University of Rochester suggests that a certain compound derived from shellfish may indeed stimulate bone repair. "There is no reason to dismiss TCM," Yao told a press conference in Beijing. "It's been used in our country for thousands of years. I don't think that it's short on science. "
1. The word "towering" in Paragraph 1 means ______.
A.large
B.fat
C.tall
D.great
A B C D
C
[解析] 词义猜测题。由第一段“If Yao Ming is not the biggest sports star in the world, he is almost certainly the tallest.”(如果姚明不是世界上最闪耀的球星，那他也一定是最高的那个。)可知，姚明的身高很突出，是奥运会参赛运动员的一项纪录，而且第一段一直在强调他的身高。另外，根据“tower(塔)”一词也可猜测联想到towring“(像塔一样)高耸的”，故选C。
2. Opponents find it very difficult to control Yao Ming because of his ______.
A.mobility
B.assault
C.defense
D.celebrity
A B C D
A
[解析] 事实细节题。定位到文章第三段第二句，根据“His assets on the court are clear enough—no NBA player of his size has ever possessed his mobility, so he is a handful for opponents on either end of the court.”可知，姚明在场上的优势很明显，没有哪个和他身高一样的NBA球星有这样的移动性，所以才会让对手觉得很难对付。
3. Yao Ming had to undergo a series of TCM treatments because ______.
A.his right foot had been hurting
B.he wanted to make a more rapid recovery
C.the surgical operation had been a failure
D.he couldn't afford all the medical expenses
A B C D
B
[解析] 事实细节题。姚明受伤的有关内容在文章第四、五段。根据第五段第一句中的“he underwent a series of traditional Chinese medicine (TCM) treatments, hoping to accelerate his recovery process”可知，姚明接受一系列传统中医治疗是为了加快脚伤的恢复进程，故选B。
4. Which statement about Yao Ming is NOT true?
A.He missed the Athens Olympics.
B.He is an NBA player.
C.He fractured his left foot.
D.He is an international figure.
A B C D
A
[解析] 推理判断题。根据第一段中的“he is the tallest player in the National Basketball Association (NBA)”可知，姚明是NBA球员，故B正确。根据第三段最后一句话中的“what makes Yao invaluable to the Rockets organization is his role as a global citizen”可知，姚明对于火箭队的价值就在于他是全球范围内的名人，故D正确。根据第四段中的“Yao would miss the rest of the NBA season and possibly the Olympics with a stress fracture in his left foot”可知，他左脚骨折，故C也正确。此外，他有可能错过的是剩下的NBA赛季以及北京奥运会，但并没有提到他错过了雅典奥运会，故本题选A。
5. In general, the Western experts' attitude towards TCM is ______.
A.indifferent
B.positive
C.negative
D.doubtful
A B C D
D
[解析] 事实细节题。由第五段第二句中的“Western experts are generally skeptical of TCM's benefits”可知，西方专家大都对传统中医持怀疑态度，skeptical和选项D中的doubtful是同义词，故选D。
第三篇
Can You Hear This?
When something creates a sound wave in a room or an auditorium, listeners hear the sound wave directly from the source. They also hear the reflections as the sound bounces off the walls, floor, and ceiling. These are called the reflected wave or reverberant (反射的) sound, which can be heard even after the sound is no longer coming from the source. The reverberation time of an auditorium is determined by the volume or interior size of the auditorium. It is also determined by how well or how poorly the walls, ceiling, floor, and contents of the room (including the people) absorb sound. There is no ideal reverberation time, because each use of an auditorium calls for different reverberation. Speech needs to be understood clearly; therefore rooms used for talking must have a short reverberation time. The full-sound performance of music such as Wagner operas or Mahler symphonies should have a long reverberation time. The light, rapid musical passages of Bach or Mozart need a reverberation time somewhere between. Acoustic problems often are caused by poor auditorium design. Smooth, curved reflecting surfaces create large reflections. Parallel (平行的) walls reflect sound back and forth, creating a rapid, repetitive pulsing effect. Large pillars (柱) and corners can cause acoustic shadows as the sound waves try to pass around the object. Some of these problems can be solved by using absorbers and reflectors to change the reverberation time of a room. For example, hanging large reflectors, called clouds, over the performers will allow some sound frequencies to reflect and others to pass to achieve a pleasing mixture of sound.
2. Wagner operas and Mahler symphonies with full-sound effect have ______.
A.a short reverberation time
B.an intermediate reverberation time
C.no reverberation time
D.a long reverberation time
A B C D
D
[解析] 事实细节题。根据文章第二段中的“The full-sound performance of music such as Wagner operas or Mahler symphonies should have a long reverberation time.”可知，瓦格纳的歌剧和马勒的交响曲听起来立体圆润是因为混响时间长，即a long reverberation time，故本题选D。
3. This passage suggests that a good auditorium should ______.
A.get rid of all reflections
B.not have absorbers
C.achieve a pleasing mixture of sound
D.have smooth surfaces
A B C D
D
[解析] 推理判断题。文章围绕混响对礼堂建筑构造的影响展开说明，最后又说到建筑内部不合理所引起的一些声学问题也可以通过改变构造来解决，从而达到良好的传声效果。根据第二段中的“each use of an auditorium calls for different reverberation”可知，礼堂需要不同的混响时间；根据第三段中的“Smooth, curved reflecting surfaces create large reflections.”可知，建筑内部应该是光滑的、有弧度的表面，这样混响的传声效果才会好。综上所述，本题选D。
4. Large pillars and comers may ______.
A.make sound rich and full
B.be cures for sound problems
C.be sources of sound problems
D.function as effectively as clouds
A B C D
C
[解析] 事实细节题。定位到文章最后一段中的“Large pillars and corners can cause acoustic shadows as the sound waves try to pass around the object...using absorbers and reflectors to change the reverberation time of a room.”由此可知，声波穿过障碍物时，建筑内的柱子和角落可能会造成声影。接着又给出了解决办法，即在室内悬挂一些反射器。由此可知，柱子和角落是引起声学问题的来源，故本题选C。
5. The word "acoustic" in the last paragraph has something to do with ______.
For centuries, people have wondered about the strange things that they dream about. Some psychologists say that this nighttime activity of the mind has no special meaning. Others, however, think that dreams are an important part of our lives. In fact, many experts believe that dreams can tell us about a person's mind and emotions. Before modem times, many people thought that dreams contained messages from God. 1 The Austrian psychologist, Sigmund Freud, was probably the first person to study dreams scientifically. He believed that dreams allow people to express the feelings, thoughts, and fears that they are afraid to express in real life. The Swiss psychiatrist (精神病学家) Carl Jung was once a student of Freud's. Jung, however, had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer. 2 For example, people who dream about falling may learn that they have too high an opinion of themselves. On the other hand, people who dream about being heroes may learn that they think too little of themselves. Modern-day psychologists continue to develop theories about dreams. For example, psychologist William Domhoff from the University of California, Santa Cruz, believes that dreams are tightly linked to a person's daily life, thoughts, and behavior. 3 Domhoff believes that there is a connection between dreams and age. His research shows that children do not dream as much as adults. According to Domhoff, dreaming is a mental skill that needs time to develop. He has also found a link between dreams and gender. His studies show that the dreams of men and women are different. 4 This is not true of women's dreams. Domhoff found this gender difference in the dreams of people from 11 cultures around the world, including both modern and traditional ones. Can dreams help us understand ourselves? Psychologists continue to try to answer this question in different ways. 5 The dream may have meaning, but it does not mean that some terrible event will actually take place. It's important to remember that the world of dreams is not the real world. A. For example, the people in men's dreams are often other men, and the dreams often involve fighting. B. Men and women dream about different things. C. A criminal, for example, might dream about crime. D. However, one thing they agree on this: If you dream that something terrible is going to occur, you shouldn't panic. E. It was only in the twentieth century that people started to study dreams in a scientific way. F. He thought people could learn more about themselves by thinking about their dreams.
1.
E
[解析] 文章主要讲的是科学家们对梦是什么的解释，以及梦与心理、与生活之间的联系。第二段中的“Before modern times, many people thought that dreams contained messages from God.”意思是，在近代以前，人们认为梦传达了上帝的旨意；第三段开头则举出弗洛伊德与荣格等近现代心理学家对梦的研究和理解。可见该空格所在句表达的应该是转折的意思，表明了现代与过去之间的不同情况，故本题选E。
2.
F
[解析] 空格前的内容“Jung believed that the purpose of a dream was to communicate a message to the dreamer.”的意思是，瑞士精神病学家荣格认为梦的目的是传达给做梦人某种信息；空格之后举例说，梦到摔倒的人可能是对自身评价过高，梦到成为英雄则对自身评价过低，不自信。可见通过梦，人们可以更了解自己，选项F承接上下文，选项中的he也对应了Jung。
3.
C
[解析] 空格所在的段落介绍了加州大学的多姆霍夫关于梦的见解。他认为梦与一个人的日常生活、思想、行为紧密相关。选项C举的例子就是对他的看法“dreams are tightly linked to a person's daily life, thoughts, and behavior”的一种解释，故本题选C。
4.
A
[解析] 空格前的内容说到梦和性别也有关，男性和女性的梦也不同；空格后的内容“This is not true of women's dreams.”意思是，女性的梦却不是这样，由此推测空格句说的应该是与男性有关的梦。选项A和B都涉及性别，但是选项B重复了空格前的句子内容“His studies show that the dreams of men and women are different.”，而选项A举的例子符合文章逻辑，故本题选A。
5.
D
[解析] 空格所在段介绍了梦的含义以及它跟现实的联系。空格后的句子“The dream may have meaning, but it does not mean that some terrible event will actually take place.”意思是，梦可能有一定含义，但不代表梦到糟糕的事它就一定会发生，梦里的世界并非现实世界。选项D的内容为就算梦到不好的事也不要慌。这也是提醒人们不要混淆现实与梦境，符合上下文逻辑，故选D。

Warmer Climate Will Bake Tropical Bugs
Global warming could cook tropical insects, with unpredictable knock-on effects, say researchers who warn that rising temperatures also 1 tropical frogs and lizards (蜥蜴). Temperatures are 2 to increase much faster in temperate (温和的)and polar (极地 的) regions than in the tropics. But no one had looked at how warming would affect insects and other cold-blooded animals 3 had evolved in tropical regions with little temperature variation. Curtis Deutsch at the University of California at Los Angeles and colleagues analysed data 4 insect survival and reproduction for 38 species in different ecosystems (生态系统), and then estimated how these values would 5 with predictions of climate change for the 21st century. The team found that the reproductive 6 of tropical insects tends to peak very close to the temperatures where they normally live, but 7 sharply at higher temperatures. This means that cranking up (提高) the heat only a small amount can exert a heavy toll, leaving insects unable to reproduce 8 enough to keep up their numbers. Temperate insects reproduce well over a broader range, and do not live as 9 to their thermal (热的) limit, so they can reproduce successfully when their climate warms more than in the tropics. "Tropical insects do very well in a narrow band of temperatures, but move them above that 10 and they die," says team member Josh Tewksbury of the University of Washington in Seattle. The heart of the 11 is temperature tolerance. Temperate-zone insects have evolved to survive the much broader temperature range of seasonal climates than have their tropical relatives. The 12 appears worse for animals that live in hot stable climate of the lower levels of tropical forests. Lizards in clear areas can find shade to cool down, but those living in the forest are already in the 13 , and there's not much they can do to get cooler, Deutsch says. Too few tropical insects have been studied so far to 14 if any particular group will be particularly hard-hit, says Tewksbury. Insects play important 15 in forest ecology (生态学). The team are now starting to evaluate how temperature affects ecological interactions of insects with other species, including crops such as African corn.
[解析] 空格所在句的意思是：Curtis Deutsch和他的同事分析了在不同的生态系统中38种昆虫的存活率与繁殖率的数据。“关于某物的数据”的词组搭配是data on sth.，故本题选A。
5.
A.meet
B.spread
C.decrease
D.change
A B C D
D
[解析] 空格所在段意思是：Curtis Deutsch和他的同事分析了在不同的生态系统中38种昆虫的存活率与繁殖率的数据，并且预测随着21世纪的气候变化这些数值将会如何______。根据第二段的“But no one had looked at how warming would affect insects and other cold-blooded animals”可知，气候变化对这些生物的影响暂时还是未知的，所以也不知道数值会如何“变化”，不知道是升高或是降低，所以选择一个中性词change，故本题选D。meet遇到，达到；spread传播，扩散；decrease降低，减少。
[解析] 空格所在句的意思是：居住在开阔空地的蜥蜴可以找树荫来乘凉，但是居住在森林的生物已经有树荫了，所以没办法找地方乘凉。根据前半句“Lizards in clear areas can find shade to cool down”可知，居住在森林的生物已经有树荫(shade)了，故本题选C。eave洞穴；sunshine阳光；open空地，户外。
