1、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。
2、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all. these and can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" and "feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road and conditions ahead of it. They watch the traffic to the car\'s left and right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the right line forthe intelligent cars, and gives instructions to the "hands" and "feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver ______ needs one second to react. Besides, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time and in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【单选题】
A.at least
B.at most
C.at last
D.at best
正确答案:A
答案解析:选项B和D是近义短语结构,因此相互排除掉。空白所在的句子说“然而,世界上最好的司机作出反应……需要1秒钟”,因此判断A(至少)是答案。第60题和第61题所在的句子把“虚拟司机”和“人类最好的司机”进行反应速度的对比(虚拟司机反应速度快),显然这是利用具体事实的分析以论证该段开头部分的观点句(He reacts quickly),由此进一步肯定第58题的答案是quickly。
3、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. What is the most important part of the Portable Light technology?【单选题】
A.HB LEDs.
B.Glass Bulbs.
C.Incandescent lights.
D.Heated metal coils.
正确答案:A
答案解析:第6段第1句提供了答案。Portable Lights技术的最主要部分是high-brightness light-emitting diodes,即高亮度发光二极管。
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.Radiocarbon is reliable in dating an object back to at least 50,000 years.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:A
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四段最后一句:Most scientists agree that this ratio is useful fordating items back to at least 50,000 years谈到科学家相信,这样的比率对于测定5万多年前的物体有用,题干是其近义解释,所以正确,答案是A。

6、Meet Your Memory1. Memory 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.2. 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 brain until it is needed; (3) retrieval (提取) refers to getting the material back out when it is needed:3. 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.4. 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.As a measure of memory, relearning is more sensitive than ______.【单选题】
A.short - term memory
B.relearning
C.needed
D.coded
E.recognition
F.slow forgetting rate
正确答案:E
答案解析:本题难度不大,答案依据比较明显,在文章第四段倒数第二句:Relearning is generally a more sensitive measure of memory than is recognition because…谈到作为测试记忆力的方法来说,再学习比识别更灵敏,回来看选项,E项recognition符合原文句意,是答案。
7、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。
8、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 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 _____ 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.by
B.away
C.along
D.with
正确答案:B
答案解析:本题难度较大,考查词义辨析,干扰项干扰较大。根据上下文逻辑,文章此处是说“当我们飞离太阳时温度会变得更低”,答案是B。
9、Dairy Price-fixing ScandalTesco is preparing a legal battle to clear its name of involvement in the dairy price-fixing scandal that has cost consumers £270 million. Failure to prove that it had no part in collusion with other supermarkets and dairy processors may land it with a fine of at least £80 million. The Office of Fair Trading (OFT) said yesterday that Asda, Sainsbury\'s and the former Safeway, plus the dairy companies Wiseman, Dairy Crest and Cheese Company, had admitted being in a cartel to fix prices formilk, butter and cheese. They were fined a total of just over £116 million as part of a leniency deal offered by the watchdog to companies that owned up quickly to anti-competitive behaviour.Officials at the OFT admitted privately that they did not think they would ever discover which company orindividual had initiated the pricing formula. But the watchdog recognises that at the time supermarkets were under pressure from politicians and farmers to raise the cost of milk to save dairy farming, though it is not certain that money found its way to farmers. The OFT claimed in September that it had found evidence that the retail chains had passed future milk prices to dairy companies, which then reached a fixed price among themselves.The average cost to each household is thought to be £11.25 over 2002 and 2003, Prices went up an extra 3p on a pint of milk, 15p on a quarter of a pound of butter and 15p on a half pound of cheese. There is no direct recompense forconsumers, however, and the money will go to the Treasury. The National Consumer Council gave warning that the admissions would dent consumer confidence in leading high street names and that people would become sceptical of their claims. Farmers forAction, thegroupof farmers that has led protests over low milk prices since 2000, is seeking legal advice on whether it can now bring a claim forcompensation.The OFT investigation is continuing, however, in relation to Tesco, Morrisons and the dairygroupLactalis McLelland, and any legal action is expected to be delayed until that is completed. Tesco was defiant and said that it was preparing a robust defence of its actions. Lucy Neville-Rolfe, its executive director, said: "As we have always said, we acted independently and we did not collude with anyone. Our position is different from our competitors and we are defending our own case vigorously. Our philosophy is to give a good deal to customers."Morrisons has supported the OFT in inquiries into the former safeway business that it took over, but in a statement said that it was still making "strong representations" in its defence. A spokeswoman forLactalis McLelland said that the company was "co-operating" with the OFT. Industry insiders suggested that the three companies were deliberately stalling the OFT investigation.Sainsbury\'s admitted yesterday that it had agreed to pay £26 million in fines, but denied that it had sought to profiteer. Justin King, the chief executive, said he was disappointed that the company had been penalised foractions meant to help farmers but recognised the benefit of a speedy settlement. Asda declined to say how much it would pay in fines and also said that its intention had been to help farmers under severe financial pressure.We may infer from Morrisons\' statement that ______.【单选题】
A.Morrisons was uncooperative with OFT
B.Morrisons was reluctant to support the inquiries into the former safeway business
C.Morrisons was trying to delay the OFT investigation
D.Morrisons was working hard to defend its interests
正确答案:D
答案解析:推理题。注意句中but表示的转折关系。行动上是一种合作态度,但还是要竭力维护自己的利益,故正确答案为D。
10、AIDSAs a science writer, I don\'t have to wear emotional armorvery often. Before I went to Zimbabwe fora visit, I had talked to other reporters who had spent time in Africa. All told me to get prepared forthe orphans, many of whom had caught the AIDS virus from their mothers and the strong desire to make everything all right forthem. Then again, nothing could have prepared me forthe visit to creche(育婴堂) forAIDS orphans in Harare, where one sick, smiling four-year-old boy tried to keep up with the other kids playing ring-around-the-rosy but was so weak he kept falling to the floor, ormeeting a 25-year-old unmarried girl who cared forher nephew Only when I got back about a week later The boy who called his aunt "Mama" was too weak even to take the piece of banana I offered. Meanwhile photojournalist Karin Retief was visiting a room at the hospice (济贫院) where she had been told a particularly sweet orphan boy stayed. At first she did not see anyone on the bed and was about to say he must be elsewhere, when suddenly she spotted his tiny arm in the air, his body lost in the folds of the bedclothes. Recently Karin wrote to me that she had been able to keep our assignment from taking too great an emotional suffering at the time. " ______, could I moum the people I met", she continued. "I sat in church and wanted to ask the priest to pray forthe people with AIDS in Zimbabwe and all over the world. Then all the people\'s faces, pain and suffering became so real, I could not get the words out. I broke down and cried and cried forthem". 【单选题】
A.where she had been told a particularly sweet orphan boy stayed
B.who had spent time in Africa
C.Only when I got back about a week later
D.even though her only income was from growing and selling a few vegetables at the local market
E.was so weak he kept falling to the floor
F.while we were visiting the orphans
正确答案:C
答案解析:句首需要大写,选项中只有C的开头是大写。另外后面的句子是倒装语序,就要考虑某些特殊的句式结构。因此选C。
