1、Genetically Modified FoodEuropean ｕｎｉｏｎenvironmental officials have determined that two kinds of genetically modified corn could harm butterflies, affect food chains ａｎｄ　disturb life in rivers ａｎｄ　streams, ａｎｄ　they have proposed a ban on the sale of the seeds, which are made by Dupont Pioneer, Dow Agrosciences ａｎｄ　Syngenta. The preliminary decisions are circulating within the European Commission, which has the final say. Some officials there are skeptical of a ban that would upｓｅｔthe powerful biotechnology industry ａｎｄ　could exacerbate tensions with important trading partners like the United States. The seeds are not available on the European market fｏｒcultivation.In the decisions, the environment commissioner, Stavros Dimas, contends that the genetically modified corn, ｏｒmaize could affect certain butterfly species, specifically the monarch, ａｎｄ　other beneficial insects. Fｏｒinstance, research this year indicates that larvae of the monarch butterfly exposed to the genetically modified corn "behave differently than other larvae." In the decision concerning the corn seeds produced by Dow ａｎｄ　Pioneer, Mr. Dimas calls "potential damage on the environment irreversible." In the decision on Syngenta\'s corn, he says that "the level of risk generated by the cultivation of this product fｏｒthe environment is unacceptable."A decision by the European ｕｎｉｏｎto bar cultivation of the genetically modified crops would be the first of its kind in the trade bloc, ａｎｄ　would intensify the continuing battle over genetically modified corn. Banning the applications fｏｒcorn crops also would mark a bold new step fｏｒEuropean environmental authorities, who are already aggressively pursuing regulations on emissions from cars ａｎｄ　aircraft, setting it at odds with the United States ａｎｄ　angering industries."These products have been grown in the U. S. ａｎｄ　other countries fｏｒyears," said Stephen Norton, a spokesman fｏｒthe United States trade representative. "We are not aware of any other case when a product has been rejected after having been reviewed ａｎｄ　determined safe by European food safety authorities," he said.Barbara Helfferich, a spokeswoman fｏｒMr. Dimas, declined to comment on the specifics of the procedure because commissioners had not yet made a final decision. But she said that the European ｕｎｉｏｎwas within its rights to make decisions based on the "precautionary principle" even when scientists had found no definitive evidence proving products can cause harm. She said that the decisions by Mr. Dimas could go before the commission within a few weeks, but she said that no date had been set. In the decisions, Mr. Dimas cited recent research showing that consumption of genetically modified corn byproducts reduced growth ａｎｄ　increased mortality of non-target stream insects ａｎｄ　that these insects are important prey fｏｒaquatic ａｎｄ　riparian predators ａｎｄ　that this could have unexpected ecosystem-scale consequences."Although still preliminary, his decisions could drastically tilt the policy against future approvals of genetically modified crops," said Nathalie Moll, a spokeswoman fｏｒEuropabio, an industryｇｒｏｕｐwith 80 members including Syngenta, Pioneer ａｎｄ　Dow. Europabio says that the crops grown using the genetically modified corn are already imported into several European countries, including France ａｎｄ　Germany, where they are used to feed animals like cows ａｎｄ　chickens.Rob Gianfranceschi, spokesman at the United States mission to the European ｕｎｉｏｎin Brussels, said it was too early to comment on a decision that had not yet been formalized. But he made clear that the United States remained frustrated with European policies on genetically modified crops.The preliminary decisions are made by ______.【单选题】

A.Dupont Pioneer, Dow Agrosciences ａｎｄ　Syngenta

B.European ｕｎｉｏｎenvironmental officials

C.European Commision

D.Starvros Dimas

正确答案:D

答案解析:细节考查题。文章的论述中多次提到Dimas先生在决议中的观点，第六段也提到他的决议虽然是初步的但可能有很大影响。由此看来，该决议是Dimas先生提出的可能性大，故正确答案为D。考生要避免受到干扰项B的影响。

2、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。

3、Lakes, Too, Feel Global WarmingThere\'s no doubt, In the last few decades, the average temperature on Earth has been higher than it has been in hundreds of years. Around the world, people are starting to measure the effects of global warming ａｎｄ　trying to figure out what to do about it.Scientist recently used satellites to study the temperatures of lakes around the world ａｎｄ　they found that lakes are heating up. Between 1985 ａｎｄ　2009, satellites recorded the night time temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer by an average of about 0.045 degree Celsius per year.In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius in just 10 years. That difference may seem small you might not even notice it in your bath. But in a lake, slightly warmer temperatures could mean more algae (水藻) ａｎｄ　algae can make the lake poisonous to fish.The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming. The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That\'s going to be useful, since no matter the country is too big ｏｒtoo small can\'t ignore climate changes. Scientists aren\'t the only ones concerned. Everyone who lives on Earth is going to be affected by the rapid warming of the planet. Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse(温室) gases we put into the air.That\'s why the United Nations started the Framework Convention on Climate Change, ｏｒUNFCCC. Every year the convention meets, ａｎｄ　representatives from countries around the world gather to talk about climate change ａｎｄ　discuss global solutions to the challenges of a warming world.The temperatures of lakes around the world have increased greatly between 1985 - 2009.【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，在文章第二段第三句：During those 24 years, the lakes got warmer-by an average of about 0.045 degree Celsius per year.很明显，每年湖水的温度平均才上升0. 045度，题干却说have increased greatly，和原文句意明显不符，答案是B。

4、Science Fiction1 Amongst the most popular books being written today are those that are usually classified asscience fiction. Hundreds of titles are published every year ａｎｄ　are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories. 2 It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some forms of ideal society, a theme that is still often found in modern stories. 3 Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verve ａｎｄ　H. G Wells, to mention just two well known authors, have been translated into many languages. 4 Modern science fiction writers don\'t write about men from Mars ｏｒspace adventure stories. They are more interested in predicting the results of technical developments on society ａｎｄ　the human mind; ｏｒin imagining future worlds that are a reflection of the world that we live in now. Because of this their writing has obvious political undertones (涵义). 5 In an age where science fact frequently overtakes (超过) science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology. Paragraph 3____【单选题】

A.A Fairly New Development

B.Classics of Science Fiction

C.Difficulty in Keeping ahead of Scientific Advances

D.Origins of Science Fiction

E.Themes of Modern Science Fiction

F.SuccessfulFilms

正确答案:B

答案解析:该段主要是在介绍经典科幻小说，其实该段第1句就已经出现了classics这个词，所以选项B是正确答案。

5、One Good Reason to Let Smallpox LiveIt\'s now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US ａｎｄ　one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). ａｎｄ　the last "official" stocks of live Virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have _____ an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines(疫苗). So once again there\'s a good reason to the virus, just in keep the disease puts in a reappearance.How do we case with the mistrust of the US ａｎｄ　Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn\'t mean the idea is rejects. If the virus is useful, then let\'s wrong it the servant of all humanity make not just a part of it.【单选题】

8、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.Radar is used to determine the characteristics of radiocarbon.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题有较大难度，答案依据不明显，需要通读全文作出判断。通读全文后可以发现文章并未提及使用雷达来进行放射性碳测定，所以本题是未提及的，答案是C。

9、Strike in MTV NetworksScores of workers from MTV Networks walked off the job yesterday afternoon, filling the sidewalk outside the headquarters of its corporate parent, Viacom, to protest recent changes in benefits. The walkout highlighted the concerns of a category of workers who are sometimes called permalancers： permanent freelancers who work like full-time employees but do not receive the same benefits.Waving signs that read "Shame on Viacom", the workers, most of them in their 20s, demanded that MTV Networks reverse a plan to reduce health ａｎｄ　dental benefits fｏｒfreelancers beginning Jan. 1. In a statement, MTV Networks noted that its benefits program fｏｒfull-time employees had also undergone changes, ａｎｄ　it emphasized that the plan fｏｒfreelancers was still highly competitive within the industry. Many freelancers receive no corporate benefits. But some of the protesters asserted that corporations were competing to see which could provide the most mediocre health care coverage. Matthew Yonda, who works at Nickelodeon, held a sign that labeled the network "Sick-elodeon". "I\'ve worked here every day fｏｒthree years-I\'m not a freelancer," Mr. Yonda said. "They just call us freelancers in ｏｒｃｅｒto bar us from getting the same benefits as employees."The changes to the benefits package were announced last Tuesday. Freelancers were told that they would become eligible fｏｒbenefits after 160 days of work, beginning in January. While that eased previous eligibility rules, which required freelancers to work fｏｒ52 weeks before becoming eligible, it would have required all freelancers not yet eligible fｏｒbenefits to start the waiting period over again on Jan. 1. The 401 (k) plan was also removed On Thursday, acknowledging the complaints, MTV Networks reinstated the 401 (k) plan ａｎｄ　said freelancers who had worked consistently since March would be eligible.Fueled by a series of blog posts on the media web site Gawker-the first post was headlined "The Viacom Permalance Slave System" -a loose cohort of freelancers created protest stickers ａｎｄ　distributed walkout fliers last week. Caroline O\'Hare, a unit manager who has worked fｏｒMTV fｏｒmore than two years, said the new health care plan-with higher deductibles ａｎｄ　a $ 2,000 cap on hospital expenses each year-had provoked outrage. "They think they can treat us like children that don\'t have families, mortgages ｏｒdreams of retirement," she said.Outside Viacom\'s headquarters, several workers held posters with the words, "There\'s too many of us to ignore." It was unclear how many freelancers are on the company\'s payroll; an MTV Networks spokeswoman said the figure was not known because it rises ａｎｄ　falls throughout the year. The company has 5,500 full-time employees, excluding freelancers, around the world.Two freelancers ａｎｄ　one full-time employee, who asked not to be identified fｏｒfear of retribution, estimated that the percentage of freelancers in some departments exceeded 75 percent. Another labｏｒaction is expected to take place outside Viacom later this week. Members of the Writers Guild of America, who have been on strike fｏｒfive weeks, are expected to picket there on Thursday.Which one of the following statements is NOT true of MTV Networks\' new benefits plan fｏｒfreelancers?【单选题】

A.Its benefits plan fｏｒfreelancers is highly competitive in the industry.

B.Its freelancers cannot receive the same benefits as the full-time employees.

C.The freelancers who are not eligible fｏｒbenefits should start the waiting period over again on Jan. 1.

D.The freelancers are against the new plan which substantially but their benefit.

正确答案:C

答案解析:细节考查题。题干考查的是与新福利方案不符的一项。只有选项C符合题意，故正确答案为C。

10、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.Long - term memory has an almost unlimited capacity ａｎｄ　a ______.【单选题】

A.short - term memory

B.relearning

C.needed

D.coded

E.recognition

F.slow forgetting rate

正确答案:F

答案解析:本题有一定难度，需要认真第三段，吃透句意。这一段谈到短期记忆和长期记忆是两个不同的过程，短期记忆遗忘率高，那么换句话说长期记忆遗忘率低，回来看选项，F项slow forgetting rate符合原文句意，是答案。
