3、Stress Lessen CourseDoreen Sykora is now a juniｏｒat McGill University. She had a difficult time when she first began college. She said, "I was always well prepared fｏｒmy examinations. But I would go in to class to take the exam, ａｎｄ　I would fall apart. I could not answer the questions correctly-even though I knew the answers! I would just blank out because of nervousness ａｎｄ　fear". Histoshi Sakamoto, an anthropology student at Temple University in Tokyo reports similar experiences. These two young students were experiencing something called test anxiety. Because when a student worries ａｎｄ　is stressed about a test, his ｏｒher mind does not work as well as it usually does. The student cannot write ｏｒthink clearly because of the severe tension ａｎｄ　nervousness. Now there are special university courses to help students. In these courses, advisors ａｎｄ　psychologists try to help students by teaching them to manage test anxiety. Such a course helps students learn to live with stress ａｎｄ　not fail because of it. First students take a practice test to measure their worry level. If the tests show that their stress level is high, the students can take a short course to manage the fear. These courses teach students how to relax their bodies. They get training to become calm in very tense situations. By controlling their nervousness, they can let their minds work more easily. Learned information then comes out without difficulty on a test. Doreen Sykora saw immediate results after taking such a course. She now has enthusiasm about the relaxation methods. "Mostly, what I do is imagine myself in a very calm place. Then I imagine myself picking up a pencil. I move slowly ａｎｄ　carefully. I breathe easily ａｎｄ　let all the tension out. With each breath, more worry leaves me. It really works too. My grades have improved greatly! I\'m really doing well at McGill now. This relaxation method works not only on examinations, but it has improved the rest of my life as well". FｏｒHistoshi in Tokyo, the results were much the same. He is enjoying school a lot more ａｎｄ　learning more. What is the similarity between Doreen Sykora ａｎｄ　Hitoshi Sakamoto?【单选题】

A.Students from the same university.

B.Failing in all the examinations.

C.Experiences of test anxiety.

D.Having the same poｏｒstudying habits.

正确答案:C

答案解析:第1段详细讲了Doreen Sykora畏惧考试的状态，在最后一句提到了Histoshi Sakamoto也有同样的经历。因此选C。

4、Radiocarbon DatingNowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), ｏｒcarbon - 14 dating. One key to understanding how ａｎｄ　why something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon -12, has six protons (质子) ａｎｄ　six neutrons (中子) in its nucleus (原子核). Carbon - 14, ｏｒC - 14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of the extra neutrons ａｎｄ　energy from the nucleus.In Libby\'s radiocarbon dating technique, the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detectｏｒａｎｄ　counter. The decay rate is used to determine the proportion of C -14 atoms in the sample being dated.Carbon - 14 is produced in the Earth\'s atmosphere when nitrogen(氮) - 14, ｏｒN - 14, interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C -14 formation is thought to occur at a constant rate. Now the ratio of C -14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful fｏｒdating items back to at least 50,000 years.All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C -14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, ａｎｄ　the C -14 already present begins to decay. Over time the amount of C - 14 in the material decreases ａｎｄ　the ratio of C - 14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C -14 atoms in a sample, the older that sample is.An atom of ordinary carbon has. six protons ａｎｄ　eight neutrons.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题难度不大，答案依据比较明显，主要答案依据在文章第二段第二句：An atom of ordinary carbon，called carbon - 12，has six protons ａｎｄ　six neutrons谈到普通碳原子有6个质子和6个中子，显然，题干和答案依据不符，答案是B。

5、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 _____ 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 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.operated

B.occurred

C.opened

D.offered

正确答案:B

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。文章此处是说“……发生在1983年的南极洲”，显然，答案是B。

6、Don\'t Rely on Plankton to Save the PlanetEncouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. Its opponents fear that will damage the marine ecosystem, ａｎｄ　now a computer model shows that the trick would also be remarkably inefficient.Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. ______Jorge Sarmiento from Princeton ａｎｄ　his colleagues developed a complex computer model to analyze how factors such as ocean chemistry ａｎｄ　water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron fｏｒa month. They found that 100 years later only between 2 ａｎｄ　13 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results."These are newer ａｎｄ　better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."Butthe take-home message is the same. Ocean fertilization is not the answer to global warming."【单选题】

A.Its opponents argue, however, that it will stop global warming.

B.Its opponents fear that will damage the marine ecosystem, ａｎｄ　now a computer model shows that the trick would also be remarkably inefficient.

C.As plankton die ａｎｄ　settle on the ocean floor, their carbon is supposedly locked up in the seabed.

D.They found that 100 years later only between 2 ａｎｄ　12 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.

E."These are newer ａｎｄ　better models,"

F.Ocean fertilization is not the answer to global warming.

正确答案:C

答案解析:空白前句句意：微小生物体在水中吸收溶解的二氧化碳，而水中被吸收的二氧化碳又会被空气中的二氧化碳所替代。

7、Arctic MeltEarth\'s North ａｎｄ　South Poles are famous fｏｒbeing cold ａｎｄ　icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter ａｎｄ　shrinks(缩小) during the summer. But fｏｒmany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent ｄｒｅｐin end of summer ice cover. Between 1981 ａｎｄ　2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. ａｎｄ　it\'s a very large 23 percent below the previous record low, which was ｓｅｔjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons fｏｒthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice ａｎｄ　open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water ａｎｄ　the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average ａｎｄ　1.5c warmer than the previous record.With both air ａｎｄ　water getting warmer, the ice is melting from both above ａｎｄ　below. In some parts of the Beaufort Sea, north of Alaska ａｎｄ　western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.What may be some of the reasons fｏｒthe ice melt in the Arctic? ______【单选题】

A.Unusually strong winds ａｎｄ　clearer skies.

B.Heavy clouds ａｎｄ　light winds.

C.Longer summers ａｎｄ　shorter winters.

D.Thin ice ａｎｄ　open water.

正确答案:A

答案解析:本题有一定的难度，但答案依据还是比较明显，不过跨越了两个段落，文章第五段谈到去年有强风刮过北极，第六段谈到科学家怀疑云层少了，所以答案是A。

8、Cell Phones1. Believe it ｏｒnot, cell phones have been around fｏｒover a quarter of a century. The first commercial cell phone system was developed by the Japanese in 1979, but cell phones have changed a lot since that time. The early cell phones were big ａｎｄ　heavy but they have developed into small ａｎｄ　light palm sized models. There are huge developments in their functions, too. We have had call forwarding, text messaging, answering services ａｎｄ　hands - free use fｏｒyears, but now there are new facilities, such as instant access to the Internet ａｎｄ　receiving ａｎｄ　sending photos.2. Cell phones have become very common in our lives. Recent statistics suggest one in three people on the planet now have cell phone, ａｎｄ　most of them say they couldn\'t live without one, Cell phones are used in every area of our lives ａｎｄ　have become a necessary tool, used fｏｒessential arrangements, social contact ａｎｄ　business. It easier to call fｏｒhelp on the highway. It possible to keep in touch with people "on the move" when people are traveling.3. Cell phones have made communication easier ａｎｄ　have reduced the need fｏｒfamily arguments f We can use cell phones to let our family know we\'ll be late ｏｒif there\'s a sudden change of plan ｏｒan emergency. Cell phones have eased the worries of millions of parents when their teenagers are out late. They can now contact their children at any time.4. This does not mean that cell phones are all good news. Cell phones have brought with them a number of new headaches fｏｒtheir owners. It costs a lot to replace stolen phones, It is becoming a frequent occurrence, ａｎｄ　have you ever seen such a huge phone bills? More serious, however, Cell phones bring the potential health problem. There are fears that radiation from the phones may cause brain tumｏｒ肿瘤). This may be a time bomb waiting to happen to younger people who have grown up with cell phones. They simply can\'t live without cell phones!Paragraph 3 ______【单选题】

A.Cell phones ａｎｄ　the family

B.Commercial cell phone systems

C.Cell phones in everyday life

D.Cell phones fｏｒteenagers

E.History of cell phones

F.Problems with cell phones

正确答案:C

答案解析:本题难度不大，主旨句比较明显，就是第二段的第一句：手机在我们日常生活中非常普遍。后面是对其的具体阐述，介绍了手机在日常生活里发挥的作用。C项Cell phones in everyday life是本段主旨句的同义解释，是答案。

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 growthWho is NOT a likely candidate fｏｒthis year\'s Nobel Prize in medicine?【单选题】

A.Elizabeth Blackburn.

B.Carol Greider.

C.Linda Buck.

D.Pierre Chambon.

正确答案:C

答案解析:从短文的头4段可以看出，只有2004年获得诺贝尔医学奖的Linda Buck不在今年的候选人范围内。

10、Waving With LightIn the Sierra Madre mountain range of west central Mexico, the native Huichol people live much the way their ancestors did without electricity. That\'s because it\'s too expensive to string power lines to the remote mountain areas where they live. To help support themselves, the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. ａｎｄ　without electricity at home ｏｒon the road, they can only work during daylight hours. When it gets dark, they must stop whatever they\'re doing. Now, a team of scientists, designers, ａｎｄ　architects are using new technologies to provide the Huichol with light after the sun sets. The scientists\' technique involves weaving tiny electronic crystals into fabrics that can be made into clothes, bags, ｏｒother items. By collecting the sun\'s energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics "Portable Lights." Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy. "Our invention," Kennedy says, "came from seeing how we could transform technology we saw every day in the United States ａｎｄ　move it into new markets fｏｒpeople who didn\'t have a lot of money."At the core of Portable Light technology are devices called high-brightness light-emitting diodes, ｏｒHB LEDs. These tiny lights appear in digital clocks, televisions, ａｎｄ　streetlights. LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give of flight we can see. Ninety percent of energy produced by incandescent lights, however, is heat ａｎｄ　invisible. With all that wasted energy, bulbs burn out quickly. They are also easily broken. LEDs, on the other hand, are like tiny pieces of rock made up of molecules that are arranged in a crystal structure. When an electric current passes through an LED, the crystal structure produces light. Unlike incandescent bulbs, they can produce light of various colors. Within an LED, the type of molecules ａｎｄ　their particular arrangement determines what colｏｒis produced. LEDs are different from light bulbs in that____. 【单选题】

A.LEDs are incandescent lights while light bulbs are not.

B.LEDs have a metal coil while light bulbs have not.

C.LEDs emit colored light while most light bulbs don\'t.

D.LEDs are made up of tiny pieces of rock while light bulbs are not.

正确答案:C

答案解析:短文第6段对light bulbs进行了描述。第2句中的those glass bulbs即指第1句中的light bulbs。因此，LEDs不是incandescent lights（白炽灯），也没有金属丝。所以A和B均是错误的。最后一段第一句“LEDs，on the other hand，are like tiny pieces of rock made up of molecules that are arranged in a crystal structure”中的“like tiny pieces of rock”不等于pieces。
