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 was the inventorof the transistorin the early 1950s.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:B
答案解析:答案相关句:Holonyak, 75,was a student of John Bardeen,an inventorofthe transistor,in the early 1950s(该句所反映的内容是:John Bardeen是20世纪50年代初期晶体管的发明者),问题句的内容与原文的内容不一致,因此选B。
2、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, orthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged ordestroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harborif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.Paragraph 2 ______【单选题】
A.Where do hurricanes usually happen?
B.What damages can a hurricane cause?
C.What should you do during a hurricane?
D.What is a hurricane?
E.What are different names of hurricanes?
F.How do you know a hurricane is coming?
正确答案:E
答案解析:本题有一定难度,需要吃透文章句意,段落主旨句比较明显,在文章第二段的第一句:Hurricanes are given a different label,depending on where they occur.回来看选项,E项简单概括了第一段的主要意思,是答案。
3、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 ______. 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 developed 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.cured
B.to cure
C.being cured
D.having been cured
正确答案:A
答案解析:本句考查的是语法。根据所给的动词,我们可以猜到本句想说的是“Joshua Salomon说,疗程较短的治疗计划可能意味着不仅仅是更多病人被治好”。这里从语法分析,应该是缺一个定语,修饰patients,cure是一个及物动词,病人应是被治疗者:选项B(to cure)不能表示被动;C和D虽然有表示被动的意思,但是C是“正在被治疗”,D是“已经被治疗”,两者隐含的时态在这里均不合适,只有A是恰当的。
4、She stood there, trembling with fear.【单选题】
A.jumping
B.crying
C.swaying
D.shaking
正确答案:D
答案解析:题干大意:她站在那儿,吓得直发抖。trembling with fear:吓得直发抖。在四个选项中,只有shaking有发抖的意思。jumping:跳。swaying:左右摇摆。故答案选D。
5、Eventually, she got a job and moved to London.【单选题】
A.Certainly
B.Luckily
C.Naturally
D.Finally
正确答案:D
答案解析:最终,她找到工作搬到伦敦去了。本题难度不大,是送分题,干扰项干扰不强,eventually和finally都指“最后,最终”,不难找到答案D。
