1、Inventｏｒof LEDWhen Nick Holonyak ｓｅｔout to create a new kind of visible lighting using semiconductｏｒalloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, ｏｒLEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights ａｎｄ　other everyday technology. On April 23,2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the lOth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors. "Anytime you get an award big ｏｒlittle. It\'s always a surprise. " Holonyrak said. Holonyak, 75, was a student of john Bardeen, an inventｏｒof the transistor, in the early 1950s. After graduate school, Holonyak worked at Ben Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches. Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, ａｎｄ　are more environmentally friendly ａｎｄ　effective. Holonyak, now a professｏｒof electrical ａｎｄ　computer engineering ａｎｄ　physics at the University of Illinois, said he suspected that LEDs would become as commonplace as they are today, but didn\'t realize how many uses they would have. "You don\'t know in the beginning. You think you\'re doing something important. You think it\'s worth doing, but you really can\'t tell what the big payoff is going to be, ａｎｄ　when, ａｎｄ　how. You just don\'t know, "he said. The Lemelson. MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award fｏｒher work on a new generation of "molecular sieves", that can separate molecules by size. Holonyak said that you should not do anything you are not interested in.【单选题】

2、How to Be a Successful BusinesspersonHave you ever wondered why some people are successful in business ａｎｄ　others are not? Here\'s a story about one successful businessperson. He started out washing dishes ａｎｄ　today he owns 168 restaurants.Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, ａｎｄ　when he was 16 years old, he learned to fly a small plane.At the age of 23 ａｎｄ　with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working fｏｒa company that rented cars.While Mr. Kazi was working at the car rental(租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. Fｏｒtwo months, he worked as a cook\'s assistant. His job was to clean the kitchen ａｎｄ　help the cook. "I didn\'t like it," Mr. Kazi says, "but I always did the best I could."One day, Mr. Kazi\'s two co - workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant.A few months later, the owners needed a manager fｏｒa new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager ａｎｄ　soon the restaurant was making a profit.A few years later, Mr. Kazi heard about a restaurant that was losing money. The restaurant was dirty inside ａｎｄ　the food was terrible. Mr. Kazi borrowed money from a bank ａｎｄ　bought the restaurant. Fｏｒthe first six months, Mr. Kazi worked in the restaurant from 8 a. m. to 10 p. m. , seven days a week. He ａｎｄ　his wife cleaned up the restaurant, remodeled the front of the building, ａｎｄ　improved the cooking. They also tried hard to please the customers. If someone had to wait more than ten minutes fｏｒtheir food, Mrs. Kazi gave them a free soda. Before long the restaurant was making a profit.A year later, Mr. Kazi sold his restaurant fｏｒa profit. With the money he earned, he bought three more restaurants that were losing money. Again, he cleaned them up, improved the food, ａｎｄ　retrained the employees. Before long these restaurants were making a profit, too.Today Mr. Kazi owns 168 restaurants, but he isn\'t planning to stop there. He\'s looking fｏｒmore poorly managed restaurants to buy. "I love it when I go to buy a restaurant ａｎｄ　find it\'s a mess," Mr. Kazi says. "The only way it can go is up. "Mr. Kazi decided to work with KFC to ______.【单选题】

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 other moving cars near it ａｎｄ　analyzes their positions. Basing on this information, it chooses the right ______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】

8、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”。

9、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon _____ you are in direct sunlight ｏｒshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.whether

B.where

C.what

D.when

正确答案:A

答案解析:本题难度不大，考查whether or的用法，答案干扰项干扰不大。可以先看选项得到信息提示。很明显，此处是whether or结构，是说“温度（的多少）取决于你是否在阳光下或阴影里”，答案是A。

10、Cloning: Future Perfect?1 A clone is an exact copy of a plant ｏｒanimal produced from any one cell. Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997, research into cloning has grown rapidly. In May 1998, scientists in Massachusetts managed to create two identical calves using cloning technology. A mouse has also been cloned successfully. But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement: "We will have managed to clone a human being within the next two years," he told the world. 2 Seed\'s announcement provoked a lot of media attention, most of it negative. In Europe, nineteen nations have already signed an agreement banning human cloning ａｎｄ　in the US the President announced: "We will be introducing a law to ban human cloning ａｎｄ　many states in the US will have passed anti-cloning laws by the end of the year". 3 Many researchers are not so negative about cloning. They are worried that laws banning human cloning will threaten important research. In March, The New Englａｎｄ　Journal of Medicine called any plan to ban research on cloning humans seriously mistaken. Many researchers also believe that in spite of attempts to ban it, human cloning will have become routine by 2010 because it is impossible to stop the progress of science. 4 Is there reason to fear that cloning will lead to a nightmare world? The public has been bombarded (轰炸) with newspaper articles, television shows ａｎｄ　films, as well as cartoons. Such information is often misleading, ａｎｄ　makes people wonder what on earth the scientists will be doing next. 5 Within the next five to ten years scientists will probably have found a way of cloning humans. It could be that pretty soon we will be able to choose the person that we want our child to look like. But how would it feel to be a clone among hundreds, the anti-cloners ask Pretty cool, answer the pro-cloners (赞成克隆的人). Paragraph 2____【单选题】

A.Strong Reactions

B.Anxiety about the Future of Cloning

C.The Right to Choose

D.WhatisCloning?

E.Arguments in Favｏｒof Cloning

F.A Common Sight

正确答案:A

答案解析:文章第2段主要讲Seed的言论引起媒体激烈的反应，故选A。
