1、Better Control of TB Seen if a Faster Cure is FoundThe World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis. Current treatments take at least six months. Patients have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure fortuberculosis would be more effective. Now a study estimates just how effective it might be. A professorof international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others. The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. and it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve. The World Health Organization ______the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment. Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance forTB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.【单选题】
A.developed
B.invented
C.delayed
D.refused
正确答案:A
答案解析:空白处的上一句实际上也起到了提示作用,可以推测,本句应该是“制订DOTS计划”,而4个选项中只有A有“制订”的意思,计划也不可能是“发明”,从上下文分析,更不可能是“推迟”或“拒绝”。
2、Looking to the FutureWhen a magazine forhigh-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would "radiate light" and "change colorwith the push of a buttons." Food would be replaced by pills. School would be taught "by electrical impulse while we sleep." Cars would have radar. Does this sound like the year 2000? Actually, the article was written in 1958 and the question was, "what will life be like in 1978?". The future is much too important to simply guess about, the way the high school students did. So experts are regularly asked to predict accurately. By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: Cities of the future would not be crowded but would have space forfarms and fields. People would travel to world in "airbuses" all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard off\'. Does that sound familiar? If the exert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982". If the professionals sometimes sound like high-school students, it\'s probably because future study is still a new field. Here is an example forfuture study. Economic forecasting, orpredicting what the economy will do, has been around fora long time. But there have been some big mistakes in this field, too. ______ In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers. One forecaster knew that predictions about the future would always be subject to significant errors. In 1957, H. J. Rand of the Rand Corporation was asked about the year 2000, "Only one thing is certain," he answered. " Children born today will have reached the age of 43."【单选题】
A.In early 1929, most forecasters saw an excellent future forthe stock market.
B.Children born today will have reached the age of 43.
C.Actually, the article was written in 1958 and the question was, "what will life be like in 1978?"
D.So experts are regularly asked to predict accurately.
E.Scientists are 80 percent accurate in predicting the future.
F.The radar equipment of cars would make traffic accidents "almost unheard off\'.
正确答案:A
答案解析:本题前面是主题句:But there have been some big mistakes in this field,too。主题句后面的句子应该是扩展句,点出big mistakes的内容或举例说明big mistakes。选项A就是big nustakes的一个例子。本题后面的句子说许多股票大跌,投资者破产,证明了预测的错误。所以选项A是正确的。
3、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all. these and can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" and "feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road and conditions ahead of it. They watch the traffic to the car\'s left and right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of ______ moving cars near it and analyzes their positions. Basing on this information, it chooses the right line forthe intelligent cars, and gives instructions to the "hands" and "feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver at least needs one second to react. Besides, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time and in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【单选题】
A.another
B.other
C.each other
D.one another
正确答案:B
答案解析:选项B和C都是“彼此、相互”,互为近义词,所以相互排除掉;空白后出现的是复数名词(cars),因此答案是B(another修饰可数名词的单数)。
4、Keeping Cut Flowers1 While everybody enjoys fresh cut flowers around his house, few people know how to keep them foras long as possible. This may be done by keeping in mind a few simple fact. 2 An important thing to remember about cut flowers is that they are sensitive to temperature. Forexample, studies have shown that cut carnations (康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care. 3 Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds orinsects, such as bees, forpollination (粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration, generates the energy the flower needs to give the flower its shape and color. The making of seeds also depends on this energy. While all giving things respire, flowers have a high level of respiration. A result of all this respiration is heat, and forflowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies. 4 How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced and the cut flower will age more slowly. 5 Another vital factorin keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to "drink" water that is dirty orotherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach (at 4% solution) be added to each liter of water. The water and solution should also be replaced each day. Another important way to prolong the life of cut flowers is____. 【单选题】
A.by keeping its original shape and color
B.in the life ofthe cut flower
C.to produce carbon dioxide
D.foras long as possible
E.by controlling temperature
F.to replace the water and solution every day
正确答案:F
答案解析:只要找到全文的最后一句就能正确回答该题。选项F符合题意,故选F。
5、Radiocarbon DatingNowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), orcarbon - 14 dating. One key to understanding how and why something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon -12, has six protons (质子) and six neutrons (中子) in its nucleus (原子核). Carbon - 14, orC - 14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of the extra neutrons and energy from the nucleus.In Libby\'s radiocarbon dating technique, the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detectorand counter. The decay rate is used to determine the proportion of C -14 atoms in the sample being dated.Carbon - 14 is produced in the Earth\'s atmosphere when nitrogen(氮) - 14, orN - 14, interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C -14 formation is thought to occur at a constant rate. Now the ratio of C -14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful fordating items back to at least 50,000 years.All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C -14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, and the C -14 already present begins to decay. Over time the amount of C - 14 in the material decreases and the ratio of C - 14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C -14 atoms in a sample, the older that sample is.The half - life of C - 14 is about 25 ,000 years.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:C
答案解析:本题有较大难度,答案依据不明显,需要通读全文作出判断。通读全文后可以发现文章并未提及碳的半衰期是25,000年,所以本题是未提及的,答案是C。

A.police
B.traffic
C.trucks
D.buses
正确答案:B
答案解析:空白所在的句子说“它们观察智能车左右两侧的…”,B(车流)放入空白处最恰当。
7、Rockets in the SkyIf someone asked you. "What coloris the sky?" I expect that you would answer, "Blue." I am afraid that you would be wrong. The sky has no color. When we see blue, we are looking at blue sunlight. The sunlight is shining on little bits of dust in the air. We know that there is air all around the world. We could not breathe without air. Airplanes could not fly without air. They need air to lift their wings. Airplanes cannot fly very high because as they go higher the air gets thinner. If we go far enough away from the earth, we find there is no air. What is the sky? The sky is space. In this space there is nothing except the sun, the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space. They have looked at them through telescopes and in this way they have found out a great deal. The moon is about 384,000 kilometers away from the earth. An airplane cannot fly to the moon but there is a thing that can fly even when there is no air. This is rocket. I am sure that you are asking. "How does a rocket fly?" If you want to know, get a balloon and then blow it up until it is quite big. Do not tie up the neck of the balloon. Let go! The balloon will fly off through the air very quickly. The air inside the balloon tries to get out. It rushes out through neck of the ball off and this pushes the balloon through the air. It does not need wings like an air plane. This is how a rocket works. It is not made of rubber like a balloon, of course. It is made of metal. The metal must not be heavy but it must be very strong. There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket, the rocket is pushed up into the air. Rockets can fly far out into space. Rockets with men inside them have already reached the moon. Several rockets, without men inside them, have been sent to other worlds much farther away. One day rockets may be able to go anywhere in the space. What coloris the sky?【单选题】
A.It is blue.
B.It is white.
C.It is grey.
D.It has no color.
正确答案:D
答案解析:根据文章第1段第3句( The sky has no color)。

A.In early 1929, most forecasters saw an excellent future forthe stock market.
B.Children born today will have reached the age of 43.
C.Actually, the article was written in 1958 and the question was, "what will life be like in 1978?"
D.So experts are regularly asked to predict accurately.
E.Scientists are 80 percent accurate in predicting the future.
F.The radar equipment of cars would make traffic accidents "almost unheard off\'.
正确答案:B
答案解析:最后一段是总结段,指出预测的不准确性。结束前用调侃的语气写道,要预测2000年将发生的事情,有一件事是不会预测错的:今天出生的婴儿到2000年是43岁(2000-1957=43)。
9、Will We Take Vacation in Spaces?When Mike Kelly first setout to build his own private space-ferry service, he figured his bread-and-butter business would be lofting (发射) satellites into high-Earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly, who runs Kelly Space & Technology out of San Bemardino, California. "I realized that real market is in space tourism."According to preliminary market surveys, there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington, Virginia, has taken more than 130 deposits fora two-hour, $98, 000 space tour tentatively and somewhat dubiously (可疑地) setto actorby 2005. Gene Meyers of the space Island Group says: "Space is the next exotic(风光奇特的) vacation spot. "This may all sound great, but there are a few hurdles (困难). Putting a simple satellite into orbit with no oxygen, life support orreturn trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. and that doesn\'t include the oust of insuring rich and possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entiregroupof entrepreneurs trying to corner (垄断) the space-tourism market have between them "just enough money to blow up one rocket."The U. S. space agency has plenty of money but zero interest in mailing space less expensive forthe little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that is inexpensive, safe and reliable. Kelly Space\'s prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in Redwood City, California, has a booster with rotors to make a helicopter-style return to Earth; Kistler Aero-space in Kirkland, Washington, is piecing together its versions from old Soviet engines, shuttle-style thermal protection tiles and an elaborate parachute system. The first passenger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can\'t be too prepared, fora trip to that galaxy far, far away. Forthose who are intent on joining the 100-mile high club, Hilton and Budget are plotting to build space hotels. Before the Russian spaceship Mir came down, some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space, and if you are thinking of staying in it, you may want to check the Michelin ratings before booking yourself a suite. Mike Kelly planned to turn his business of making bread and butter into a business that is engaged in space tourism. 【单选题】
A.Right
B.Wrong
C.Notmentioned
正确答案:B
答案解析:理解第1段第1句的关键是bread-and-butter,作为形容词,它的意思是“基本的、日常的”,而不是“面包与黄油”。由此可见,Mike Kelly的初衷并不是投身于太空旅行,所以题干的说法是错误的。
10、The index is the government\'s chief gauge of future economic activity.【单选题】
A.measure
B.opinion
C.evaluation
D.decision
正确答案:A
答案解析:题干大意:该指数是主要衡量未来政府的经济活动的。画线词gauge:衡量标准,这里可以和measure替换。evaluation:评价,估计。opinion:想法,观点。故答案选A。
