1、Weaving 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 is 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 off light 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.The central part of the Portable Lights technology is ______.【单选题】

A.glass bulbs

B.digital clocks

C.incandescent lights

D.HB LEDs

正确答案:D

答案解析:本题有一定难度，关键在吃透句意，答案依据比较明显，带着题干信息词回文章定位，答案依据主要在文章第五段第一句：At the core of Portable Light technology are devices called high - brightness light - emitting diodes ｏｒHB LEDs。其中core和题干里的central part是同义词，回来看选项，D项和原文句意相符，答案是D。

2、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. Some form of ideal society is____. 【单选题】

A.concerned with the problems that we will have to solve in the future

B.reading books of science fiction

C.political implication

D.a recurrent theme

E.read worldwide

F.translated into many languages

正确答案:D

答案解析:本题答案的依据是在第2段最后一句，句中的theme指该句的前半部分，而atheme that is still often found in modern stories这句话换一种说法就成了a recurrent theme（一个反复出现的主题），故选D。

3、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.The writer\'s attitude to Tesco can be said to be ______.【单选题】

A.biased

B.objective

C.sympathetic

D.optimistic

正确答案:B

答案解析:态度题。通过阅读整篇文章可以看出，作者虽然在文章中讲述了关于Tesco的事件，但言语和措辞比较客观，并未作出任何掺杂个人意见的评论，故正确答案为B。

4、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 found 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 _____ 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】

A.for

B.in

C.on

D.with

正确答案:D

答案解析:本题有一定难度，考查介词with的用法，干扰项有一定的干扰。with support，固定搭配，指“在……帮助下”，此处指“在国际社会帮助下”，原句比较好的理解语序是：Keep the virus in a well - guarded UN laboratory with international support…，答案要根据介词的基本含义和用法来判断，答案是D。

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.Which of the following is the most important advantage according to the passage?【单选题】

A.Reducing the cost of your daily newspaper.

B.Lowering the price of your television program.

C.Making it possible to provide fｏｒexport at good price.

D.Providing a promise of reasonable value in the products ａｎｄ　services you buy.

正确答案:D

答案解析:选项A、B、C、D都是提到的好处，但是从文章第2段第1句可知，最重要的是广告能提供产品和服务的价值承诺。因此选D。

6、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.Scientists have been keeping records of lake temperatures fｏｒover 30 years.【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，在文章第二段第二句：Between 1985 ａｎｄ　2009，satellites recorded the nighttime temperatures of the surfaces of 1671 akes.很明显，是24年，而不是30多年，题干和原文句意不符，答案是B。

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!We can use cell phones to communicate with others when we encounter ______.【单选题】

A.a necessity

B.an emergency

C.a number of new headaches

D.family arguments

E.big ａｎｄ　light palm - sized models

F.countless new facilities

正确答案:B

答案解析:本题难度不大，答案依据比较明显，答案依据是第三段第二句：We can use cell phones to let our family know we\'ll be late ｏｒif there\'s a sudden change of plan ｏｒan emergency.很明显答案是B。

9、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.Remembering involves getting the material back out when it is ______.【单选题】

A.short - term memory

B.relearning

C.needed

D.coded

E.recognition

F.slow forgetting rate

正确答案:C

答案解析:本题难度不大，答案依据比较明显，在文章第二段：…getting the material back out when it is needed回来看选项，C项needed符合原文句意，是答案。

10、DietPersons who are overweight should watch their diet carefully in ｏｒｃｅｒto lose pounds. The best way to do this is to start a weight control program. At first it is wise to talk with your doctor. He can advise you of the number of calories you should have in your meals each day. He can tell you about exercising while on your diet. A good rule is to lose slowly. A loss ofa pound ｏｒtwo is plenty. Plan meals around foods you know. This means that it is wise to include foods that you are used to ａｎｄ　that are part of your regular eating habits. When you have lost the weight you wish, simple items can be added to your diet so that you can maintain the weight you want. While you are dieting, try to build a pattern of eating that you can follow later to maintain your desired weight. When dieting, choose low-calorie foods. Avoid such items as fats, fried food, sweets, cakes, cream ａｎｄ　soft drinks. Try to take coffee ａｎｄ　tea without sugar ｏｒcream. Snacks can be part of your diet. Fｏｒexample, a piece of fruit ｏｒa simple dessert saved from mealtime can be eaten between meals. Keep busy! This way you will not be tempted to go off the diet. Make full use of opportunities to exercise. Try walking instead of riding whenever possible. Happy dieting !What is the main idea of the passage?【单选题】
