1、Seeing Red Means Danger AheadThe colｏｒred often means danger ａｎｄ　by paying attention, accidents can be prevented. In the future, the colｏｒred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports ｏｒother kinds of materials could one day contain a colｏｒswitching material. It will turn red before a structure collapses ｏｒfalls apart. The secret behind the colｏｒswitching material is a particular type of molecule. A molecule is aｇｒｏｕｐof atoms held together by chemical bonds. Molecules come at all shapes ａｎｄ　sizes, ａｎｄ　make up everything. You can see, touch ｏｒfeel. How a molecule behaves depends on ______ kinds of atoms it contains, ａｎｄ　how they\'re held together. When a polymer (聚合物) containing a colｏｒswitching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" ｏｒweak, one of the mechanophore bonds breaks ａｎｄ　the material turns red. "It\'s a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos ａｎｄ　her team tested the colｏｒswitching polymers in their lab. The test results proved encouraging. There is a way to get rid of the colｏｒlight when a bright light is shone on the mechanophore. The broken bond is fixed ａｎｄ　the red colｏｒdisappears. This "self-healing" may be a problem fｏｒengineers. They need to use the colｏｒchanger in big construction projects that will be outside in sunlight. ａｎｄ　sunlight will make the mechanophore\'s warming system useless. Sottos ａｎｄ　her fellow scientists still have a lot of work to do before the colｏｒswitching molecules can be used outside the lab. 【单选题】

A.why

B.how

C.what

D.where

正确答案:C

答案解析:本句的意思是分子的行为取决于组合成分子的原子种类和它们的组合方式。所以kind前应加what。

2、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building ａｎｄ　that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home fｏｒblind people in Sommerｓｅｔａｎｄ　a resource centre fｏｒthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the ______ is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the doｏｒwithout a sound alarm, but only 15 seconds with one. Withington studies how the brain processes sounds at the university. She says that the source of a wide bａｎｄ　of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising ｏｒfalling frequencies to indicate whether people should go up ｏｒdown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【单选题】

A.noise

B.sound

C.music

D.bell

正确答案:B

答案解析:句子前半句是说a wide range of frequencies，所以发出的应是sound，因此答案选B。

3、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 whether you are in direct sunlight ｏｒshade. Obviously, -120℃ is colder than our body can _____ 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.safely

B.sadly

C.repeatedly

D.freely

正确答案:A

答案解析:本题有一定难度，考查词义辨析，但干扰项干扰不大。可以先看选项得到信息提示。根据上下文逻辑，文章此处是说“零下120度比我们身体所能忍受的安全温度冷得多”，答案是A。

4、Seeing Red Means Danger AheadThe colｏｒred often means danger ａｎｄ　by paying attention, accidents can be prevented. In the future, the colｏｒred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports ｏｒother kinds of materials could one day contain a colｏｒswitching material. It will turn red before a structure collapses ｏｒfalls apart. The secret behind the colｏｒswitching material is a particular type of molecule. A molecule is aｇｒｏｕｐof atoms held together by chemical bonds. Molecules come at all shapes ａｎｄ　sizes, ａｎｄ　make up everything. You can see, touch ｏｒfeel. How a molecule behaves depends on what kinds of atoms it contains, ａｎｄ　how they\'re held together. When a polymer (聚合物) containing a colｏｒswitching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" ｏｒweak, one of the mechanophore bonds ______ ａｎｄ　the material turns red. "It\'s a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos ａｎｄ　her team tested the colｏｒswitching polymers in their lab. The test results proved encouraging.

A.closes

B.breaks

C.increases

D.bums

正确答案:B

答案解析:前文为bond，意为联系，后文说到变红，说明不是在常态之下，那么联系是常态，联系断开才与红相对应，所以选break。

5、At first, all the people laughed at his ridiculous suggestion. 【单选题】

A.amusing

正确答案:D

答案解析:ridiculous：荒谬的、可笑的，和foolish（愚蠢的）意思比较接近；amusmg：逗人发笑的；shocking：令人震惊的；frightening：令人害怕的。

6、What are my chances of promotion if I stay here?【单选题】

A.retirement

B.advertisement

C.advancement

D.replacement

正确答案:C

答案解析:如果我还待在这干，我有升职的机会吗？promotion指“提升，晋级”，和advancement的引申意义“晋升”是同义词，A项指“退休”，B项指“广告”，D项指“代替”，三项的干扰性不强。本题考查的是advancement的引申意义，有一定难度。

9、Medicine Award Kicks off Nobel Prize AnnouncementsTwo scientists who have won praise fｏｒresearch into the growth of cancer cells could be candidates fｏｒthe Nobel Prize in medicine when the 2008 winners are presented on Monday, kicking off six days of Nobel announcements. Australian-born U. S. citizen Elizabeth Blackburn ａｎｄ　American Carol Greider have already won a series of medical honors fｏｒtheir enzyme research ａｎｄ　experts say they could be among the front-runners fｏｒa Nobel. Only seven women have won the medicine prize since the first Nobel Prizes were handed out in 1901. The last female winner was U. S. researcher Linda Buck in 2004, who shared the prize with Richard Axel. Among the pair\'s possible rivals are Frenchman Pierre Chambon ａｎｄ　Americans Ronald Evans ａｎｄ　Elwood Jensen, who opened up the field of studying proteins called nuclear hormone receptors. As usual, the award committee is giving no hints about who is in the running before presenting its decision in a news conference at Stockholm\'s Karolinska Institute. Alfred Nobel, the Swede who invented dynamite, established the prizes in his will in the categories of medicine, physics, chemistry, literature ａｎｄ　peace. The economics prize is technically not a Nobel but a 1968 creation of Sweden\'s central bank. Nobel left few instructions on how to select-winners, but medicine winners are typically awarded fｏｒa specific breakthrough rather than a body of research. Hans Jornvall, secretary of the medicine prize committee, said the 10 million kronｏｒ(US$1. 3 million) prize encourages groundbreaking research but he did not think winning it was the primary goal fｏｒscientists. "Individual researchers probably don\'t look at themselves as potential Nobel Prize winners when they\'re at work," Jornvall told The Associated Press. "They get their kicks from their research ａｎｄ　their interest in how life functions. "In 2006, Blackburn, of the University of California, "San Francisco, ａｎｄ　Greider, of Johns Hopkins University in Baltimore, shared the Lasker prize fｏｒbasic medical research with Jack Szostak of Harvard Medical School. Their work ｓｅｔthe stage fｏｒresearch suggesting that cancer cells use telomerase to sustain their uncontrolled growthThe research by Blackburn ａｎｄ　Greider helps suggest the role of____. 【单选题】

A.money in medical research.

B.proteins in cancer treatment.

C.hormones in the functioning of life.

D.telomerase in the growth of cancer cells.

正确答案:D

答案解析:短文的最后一句话表明，研究显示癌细胞利用端粒酶来支持其无限增殖，而这几位科学家的工作为这种研究打下了基础。

10、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 believed that his students that were working with him on the project would get the Lemelson-MIT Prize sooner ｏｒlater.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:需要注意题干中出现的修饰词sooner ｏｒlater（迟早）。利用题干中提到的新信息一他的学生，作为答案线索。在下文的内容中也没有看到有关“Holonyak对其学生的期望”的话语，因此选C。
