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.All of the following are disadvantages of incandescent lights EXCEPT that ______.【单选题】

A.they are not bright enough

B.they burn out quickly

C.they are easily broken

D.they waste most of the energy produced

正确答案:A

答案解析:本题难度较大，需要通读全文，寻找答案依据。通读全文可以发现，只有they are not bright enough是文章未提到的，答案是A。

3、Storms Sink ShipsRescuers have found the bodies of over 130 people killed in two ferry disasters in Bangladesh. The accidents happened during a storm that hit the country on April 21. Hundreds more are missing ｏｒfeared dead. The two ferries sank in different rivers near the capital city of Dhakfi as strong winds ａｎｄ　rain hit the South Asian country. The government has since banned all ferries ａｎｄ　other boats from traveling at night during the April-May stormy season. One of the ferries, MV Mitali, was carrying far more people than it was supposed to. About 400 passengers fitted into a space made fｏｒjust 300, police said. The second ferry carried about 100 passengers. "The number of deaths is certain to rise." said an official in charge of the rescue work. "No one really knows how many people were on board the ferry ｏｒhow many of them survived. Ferries in Bangladesh don\'t always keep passenger lists, making it difficult to determine the exact number of people on board. Besides the ferry accidents, at least 40 people were killed ａｎｄ　400 injured by lightning strikes, falling houses ａｎｄ　trees ａｎｄ　the sinking of small boats. Storms are common this time of year in Bangladesh, as are boating accidents. Ferry disasters take away hundreds of lives every year in a nation of 130 million people. Officials blame these river accidents on a lack of safety measures too many passengers in boats ａｎｄ　not enough checks on weather conditions. Ferries are a common means of transport in Bangladesh. It is a country covered by about 230 rivers. Some 20,000 ferries use the nation\'s Waterways every year. ａｎｄ　many of them are dangerously overcrowded. Since 1977, more than 3,000 people have died in some 260 boating accidents.How many passengers was MV Mitali designed to carry?【单选题】

A.500

B.100

C.400

D.300

正确答案:D

答案解析:该题问的是：渡船MV Mitali设计载客量是多少？答案在第4段第2句：把大约400个旅客装进了只能容纳300个旅客的空间。

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 ______ 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 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.until

B.although

C.after

D.before

正确答案:D

答案解析:本句意为当建筑物要倒塌时，它会变成红色。那么按照逻辑推理，应该是倒塌前变红色才会起作用，所以before符合题意；although显然文不对题；until与after，逻辑不对。

5、Houses of the FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict. What will our home be like then?Future houses will have to be flexible. In thirty years\' time even more of us will be working from home. So we will have to be able to use areas of the house fｏｒwork fｏｒpart of the day ａｎｄ　fｏｒliving fｏｒthe rest. Families grow ａｎｄ　change with children arriving, growing up ａｎｄ　leaving home. The house of the future will have to grow ａｎｄ　change with the family. Nothing will be as fixed as it is now. The house will always be changing to meet changing needs.Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines ａｎｄ　discuss with them what to do. Like this, "We\'ll be having a party this weekend. What food shall we cook?" ａｎｄ　the machine will tell us what food we will have to buy ａｎｄ　how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check.The house of the future will be personal, each house will be different. You will be able to change the colｏｒof the wall easily.You won\'t have to paint them-you\'ll be able to tell the wall to change the color! ａｎｄ　if you don\'t like the colｏｒthe next day, you will be able to have a new one. _____!【单选题】

A.You will be able to change the colｏｒof the wall easily.

B.The only thing you won\'t be able to do is move the house somewhere else!

C.ａｎｄ　the machine will tell us what food we will have to buy ａｎｄ　how to cook it.

D.What will our home be like then?

E.The house of the future will have to grow ａｎｄ　change with the family.

F.The kids might take their bedrooms with them as they leave.

正确答案:B

答案解析:本题有一定难度，可用排除法和代入法。本题的上文谈到了你对房子颜色所能做的事情，本题是全段结尾，各种表述可能都有，所以可用排除法和代入法。A，C，D，E都被使用可排除，把B，F代入到文章里，可以确定B是正确答案。

6、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 _____ 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 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】

9、Easy ListeningStudents should be jealous. Not only do babies get to doze their days away, but they\'ve also mastered the fine art of learning in their sleep. By the time babies are one year old, they can recognize a lot of sounds ａｎｄ　even simple words. Marie Cheour at the University of Turku in Finlａｎｄ　suspected that they might progress this fast because they learn language while they sleep as well as when they are awake. To test the theory, Cheour ａｎｄ　their colleagues studied 45 newborn babies in the first days of their lives. They exposed all the infants to an hour of Finnish vowel sounds one that sounds like "oo"； another like "ee" ａｎｄ　the third boundary vowel peculiar to Finnish ａｎｄ　similar languages that sounds like something in between. EEG (脑电图) recording of the infants brains before ａｎｄ　after the session showed that the newborns could not distinguish the sounds. Fifteen of the babies then went back with their mothers, where the rest were split into two sleep-study groups. Oneｇｒｏｕｐwas exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to the other, easier-to-distinguish vowel sounds. When tested in the morning, ａｎｄ　again in the evening, the babies who\'d heard the tricky boundary vowels all night showed brainwave activity indicating that they could now recognize this sound. They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all. Cheour doesn\'t know how babies accomplish this nighttime learning, but she suspects that the special ability might indicate that unlike adults, babies don\'t "turn off" their cerebral cortex (大脑皮层) while they sleep: The skill probably fades in the course of the first years of life, she adds so forget the idea that you can pick up the tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders. Babies can learn language even in their sleep. 【单选题】

A.Right

B.Wrong

C.Notmentioned

正确答案:A

答案解析:选A的依据是第2段最后一句。
