1、Inventor of LED- LED的发明者【近义词】 When Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes or1 LEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his

2、 students have continued his work, developing lighting used in traffic lights and other everyday technology.【反义词】On April 23, 2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the 10th year that the Lemelson-MIT Program at the Massachusetts Institute of

3、Technology（MIT）has given the award to prominent inventors.【词源解析】Anytime you get an award, big or little2, its always a surprise, Holonyak said.Holonyak, 75, was a student of John Bardeen, an inventor of the transistor, in the early 1950s. After graduate school3, Holonyak worked at Bell Labs. He late

4、r went to General Electric4, where he invented a switch now widely used in house dimmer switches5.【相关短语】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, be wanted to generate visible lig

5、ht. The LEDs he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and cost effective.【派生词】Holonyak, now a professor of electrical and computer engineering and physics at the University of Illinois, said he suspected that LEDs would become

6、as commonplace as they are today. But didnt realize how many uses they would have.【近义词】You dont know in the beginning. You think youre doing something important, you think its worth doing, but you really cant tell what the big payoff is going to be, and when, and how. You just dont know, he said.【词源

7、解析】The Lemelson-MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson- MIT Lifetime Achievement Award for her work on a new generation of molecular sieves that can separate molecules by size.【近义词】1Holonyaks colleagues thought he would fail in his research on LEDs at the time whe

That would be good news for governments, farmers and others seeking to plan for the droughts and heavy rainfall that El Nino can produce in various parts of the world.【反义词】Using a computer, the researchers

14、matched sea-surface temperatures to later El Nino occurrences between 1980 and 2000 and were then able to anticipate El Nino events dating back to 1857, using prior sea-surface temperatures. The results were reported in the latest issue of the journal Nature.【派生词】The researchers say their method is

15、not perfect, but Bryan CWeare, a meteorologist at the University of California, Davis, who was not involved in the work, said it “suggests2 El Nino is indeed predictable.”【相关短语】“This will probably convince others to search around more for even better methods,” said Weare. He added that the new metho

16、d “makes it possible to predict El Nino at long lead times3.” Other models also use sea-surface temperatures, but they have not looked as far back because they need other data, which is only available for recent decades, Weare said.【词源解析】The ability to predict the wanning and cooling of the Pacific

17、is of immense importance4. The 1997 El Nino, for example, caused an estimated $20 billion in damage worldwide, offset by beneficial effects in other areas, said David Anderson, of the European Centre for Medium-Range Weather Forecasts in Reading, England. The 1877 El Nino, meanwhile, coincided with

18、a failure of the Indian monsoon and a famine that killed perhaps 40 million in India and China, prompting the development of seasonal forecasting, Anderson said.When El Nino hit in 1991 and 1997, 200 million people were affected by flooding in China alone, according to a 2002 United Nations report.【

19、反义词】While predicting smaller El Nino events remains tricky, the ability to predict larger ones should be increased to at least a year if the new method is confirmed.【词源解析】 El Nino tends to develop between April and June and reaches its peak between December and February. The warming tends to last be

20、tween 9 and 12 months and occurs every two to seven years.【相关短语】The new forecasting method does not predict any major El Nino events in the next two years, although a weak warming toward the end of this year is possible.【派生词】1The method used by the Columbia University researchers can predict El Nino

21、 a few months in advance.ARight BWrong CNot mentioned2The Columbia University researchers studied the relationship between the past El Nino occurrences and sea-surface temperatures.ARight BWrong CNot mentioned3The Columbia University researchers are the first to use sea-surface temperatures to match

22、 the past El Nino occurrences.ARight BWrong CNot mentioned4Weares contribution in predicting El Nino was highly praised by other meteorologists.ARight BWrong CNot mentioned5According to a Chinese report, the flooding in China caused by El Nino in 1991 and 1997 affected 200 million Chinese people.ARi

23、ght BWrong CNot mentioned6It takes about eight months for El Nino to reach its peak.ARight B Wrong CNot mentioned7A special institute has been set up in America to study El Nino.ARight BWrong CNot mentioned【词源解析】当某些预报方法不能提前几个月成功预测1997年厄尔尼诺现象的时候，哥伦比亚大学的研究人员说他们的方法可以提前两年预测厄尔尼诺现象。这对全世界各地的政府、农民和其他寻求为厄尔尼诺

24、带来的干旱和大雨做准备的人来说是一条好消息。研究人员使用计算机把1980年和2000年之间的海面温度和后来的厄尔尼诺的发生联系起来，进而能够用之前的海面温度预测远至1857年的厄尔尼诺现象。研究结果刊登在最新的自然杂志上。【反义词】研究人员说他们的方法并不完美，但加利福尼亚大学戴维斯分校的气象学家Bryan C. Weare说这种方法显示出厄尔尼诺是可以预测的，尽管他自己并没有参加研究工作。Weare说：“这会促使其他人去寻找更好的办法。”他还补充说，新的方法“使在提前很长的一段时间里预测厄尔尼诺现象成为可能”。其他方法也使用海面温度，但他们没能回顾得那么久远是因为缺少其他资料，而这些资料在近

25、几十年才能够获得。【派生词】预测太平洋的升温和降温有极其重要的意义。英国Reading的欧洲中级天气预报中心的David Anderson说：以1997年的厄尔尼诺为例，它导致了全球范围内约200亿美元的损失，抵消了在其他一些地区的良性影响；1877年的厄尔尼诺与印度遭受的季风和饥荒同时发生，导致了印度和中国约4 000万人丧生，结果刺激了季节性预报的发展。【近义词】根据2002年的联合国报道，1991年和1997年厄尔尼诺爆发的时候，仅中国就有2亿人受到洪水的侵害。然而小的厄尔尼诺预测还是难以捉摸的，如果新的方法被认可的话，对大型厄尔尼诺现象的预测至少应该被提前一年。厄尔尼诺总是在4月和6月

26、期间形成，在12月和翌年2月之间达到髙峰。气候总是在9月和12月之间变暧，并且每2 7年出现一次。尽管气温在年底的时候有可能微弱上升，新的预测方法预计未来两年不会出现大的厄尔尼诺现象。Engineering Ethics-工程道德【近义词】 Engineering ethics is attracting increasing interest in engineering universities throughout the nation. At Texas A&M University, evidence of this interest in professional ethics c

27、ulminated in the creation of a new course in engineering ethics, as well as a project funded by1 the National Science Foundation to develop material for introducing ethical issues into required undergraduate engineering courses. A small group of faculty and administrators actively supported the grow

28、ing effort at Texas ASM, yet this group must now expand to meet the needs of increasing numbers of students wishing to learn2 more about the value implications of their actions as professional engineers.【派生词】The increasing concern for the value dimension3 of engineering is, at least in part, a resul

29、t of the attention that the media has given to cases such as the Challenger disaster, the Kansas City Hyatt-Regency Hotel walkways collapse, and the Exxon oil spill. As a response to this concern, a new discipline, engineering ethics, is emerging. This discipline will doubtless4 take its place5 alon

30、gside such well-established fields as medical ethics, business ethics, and legal ethics.【相关短语】The problem presented by this development is that most engineering professors are not prepared to introduce literature in engineering ethics into their classrooms. They are most comfortable with quantitativ

31、e concepts6 and often do not believe they are qualified to lead class discussions on ethics. Many engineering faculty members do not think that they have the time in an already overcrowded syllabus to introduce discussions on professional ethics, or the time in their own schedules to prepare the nec

32、essary material. Hopefully, the resources presented herein will be of assistance.【反义词】1Engineering ethics is a compulsory subject in every institute of science and technology in the Uniled States.ARight BWrong CNot mentioned2The number of students wishing to take the course of engineering ethics is

33、declining at Texas A&SM University.ARight BWrong CNot mentioned3The National Science Foundation involves itself directly in writing up material about ethical issues.ARight BWrong CNot mentioned4It seems that medical ethics and business ethics are more mature than engineering ethics.ARight BWrong CNo

34、t mentioned5Several engineering professors have quit from teaching to protest against the creation of a new course in engineering ethics.ARight BWrong CNot mentioned6Many engineering professors may not have time to prepare material for class discussion on professional ethics.ARight BWrong CNot menti

35、oned7It is likely that following this introductory passage, the author will provide the necessary material related to the topic of engineering ethics.ARight BWrong CNot mentioned【词源解析】工程道德在全美的工程类院校里越来越受到关注。在得克萨斯州的大学，随着工程道德这门新课的开设以及由全美科学基金会提供基金、旨在为大学工程类必修课程提供道德问题方面的材料的项目的启动，人们对职业道德的关注达到了顶峰。一个由教师和管理人员

36、组成的小组对得克萨斯州A大学的不懈努力予以了积极的支持，但是由于越来越多的学生希望能够更加了解作为职业工程人员自己的行为的价值含义，为了满足这些需求，目前该小组必须发展壮大。【相关短语】人们之所以对工程价值尺度愈发关注，至少部分原因是由于媒体对挑战者号灾难、堪萨斯城Hyatt-Regency旅馆通道的坍塌以及Exxon石油泄漏等事件的关注所引起的。为了响应人们的关注，一个新的学科工程道德应运而生。同医学道德、商业道德和法律道德这些已经确立的学I科一样，该学科无疑也将确立起自己的地位。【近义词】开发这一新学科所面临的问题是，大部分工程教授不愿意将工程道德方面的资料引进课堂。他们满足于使用以数字表

37、达的概念，不相信自己有资格就工程道德问题在课堂上展开讨论。许多工程类教授认为课程安排紧张，没有时间在课堂上就职业道德问题进行讨论，或者觉得自己没有时间去准备必要的材料。希望这里提供的资料会有所帮助。二、Soot and Sow：a Hot Combination-煤灰与白雪：“火热的组合【相关短语】1New research from NASA scientists suggests emissions of black soot alter the way sunlight reflects off snow. According to a computer simulation, blac

38、k soot may be responsible for 25 percent of observed global warming over the past century.【反义词】2Soot in the higher latitudes of the Earth, where ice is more common, absorbs more of the suns energy and warmth than an icy, white background. Dark-colored black carbon, or soot, absorbs sunlight, while l

39、ighter colored ice reflects sunlight.【近义词】3Soot in areas with snow and ice may play an important role in climate change. Also, if snow and ice covered areas begin melting, the warming effect increases, as the soot becomes more concentrated on the snow surface. “This provides a positive feedback, as
