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。

A.beats

B.maintains

C.matches

D.tries

正确答案:A

4、Meet Your MemoryMemory is something that cannot be seen, touched ｏｒweighed. It is thought to be abstract. It is a ｓｅｔof skills rather than an object. Neither is there a single standard fｏｒjudging a good ｏｒpoｏｒmemory. There are a number of different ways in which a person may have a "good" memory.Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the blain until it is needed; ａｎｄ　(3) retrieval (提取) refers to getting the material back out when it is needed.Memory consists of at least two different processes: short-term memory ａｎｄ　long-term memory. Short-term memory has a limited capacity ａｎｄ　a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), ｏｒgrouping separate bits of information into larger chunks. Long-term memory has an almost unlimited capacity.One measure of memory is recall, which requires you to produce information by searching the memory fｏｒit. In aided recall, you are given cues (提示) to help you produce the information. In free-recall learning, you recall the material in any order; in serial learning, you recall it in the ｏｒｃｅｒit was presented; ａｎｄ　in paired-associate learning, you learn pairs of words so that when the first word is given, you can recall the second word. A second measure of memory is recognition in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time ａｎｄ　how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall. Paragraph 1 ______.【单选题】

A.Why do we forget things?

B.How do we measure memory?

C.What are the stages memory consists of?

D.What is the difference between short-term memory ａｎｄ　long-term memory?

E.What is memory?

F.Who may have a poｏｒmemory?

正确答案:E

答案解析:第一段主题句为第一句Memory is something that cannot be seen, touched ｏｒweighed. 记忆力看不见、摸不着、也不可衡量。该段分别从这三个方面对记忆力进行了简单定义。E选项What is memory?（什么是记忆力？）与其意思一致，故E为正确答案。

5、The Value of AdvertisementMoney spent on advertising is worth spending. It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market ａｎｄ　making it possible to provide fｏｒexport at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demａｎｄ　it causes an increased need fｏｒlabor, ａｎｄ　is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, ａｎｄ　travel by bus ｏｒsubway would cost more. ａｎｄ　perhaps most important of all, advertising provides a promise of reasonable value in the products ａｎｄ　services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people fｏｒa little while through misleading advertising. He will not do so fｏｒlong, fｏｒthe public has the good sense not to buy the poｏｒgoods more than once. If you see a product frequently advertised, it is the proof I know that the product does what is promised fｏｒit, ａｎｄ　that it has good value. Advertising does more fｏｒthe good of the public than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its messages were nothing but information, that would be difficult to get more people to buy, fｏｒeven the choice of the colｏｒof a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.From the first paragraph we can see the writer believes that____.【单选题】

A.advertisements are worth reading

B.money spent on advertising is worthless

C.it is worthwhile spending money on a lot of things

D.to spend money on advertising is worthwhile

正确答案:D

答案解析:第1句是主题句，花在广告上的钱是值得花的。接下的句子对是这一句的进一步阐述。因此答案是D。
