1、Some Unusual CelebrationsSome holidays are well - known all around the world. Among them are New Year\'s Eve celebrations. Also common are days in honｏｒof love ａｎｄ　friendship, like Valentine\'s Day. Each country has its own special holidays too, often to mark important events in its history. Schools, banks ａｎｄ　government offices all close on days like these. _____ A few of them are really very strange.Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool\'s Day, fｏｒexample. No one knows when ｏｒwhy it began. Today it is celebrated in many countries—France, Englａｎｄ　ａｎｄ　Australia, among others. On this day, people play practical jokes. Jokes are supposed to be funny, but these jokes do not make everyone laugh. The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you?Dyngus Day in Polａｎｄ　seems strange too. On this day, it is traditional fｏｒboys to pour water over the heads of girls. Here is the strangest part, they do it to girls they like.Other unusual celebrations take place in a single city ｏｒtown. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. Then begins the world-s biggest food fight. Fｏｒtwo hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains ａｎｄ　catch a wild goat. They bring him back to town, put a crown on his head, ａｎｄ　make him king fｏｒthree days.There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea fｏｒa new holiday ａｎｄ　tries to get others to accept it. Whose idea was Public Sleeping Day? That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 29. That is supposed to be Toothache Day.Do you like the idea of inventing a new holiday? If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.【单选题】

2、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。

4、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.By the end of summer 2007 the ice cover in the Arctic was ______【单选题】

A.38 million square kilometers

B.4.2 million square kilometers

C.1.13 million square kilometers

D.11.4 million square kilometers

正确答案:B

答案解析:本题难度不大，答案依据比较明显，文章第四段第二句谈到了，到2007年夏季结束时，冰层缩减至仅覆盖420万平方公里，所以答案是B。

5、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. The study shows that the infant\'s cerebral cortex is working while he is asleep. 【单选题】

A.Right

B.Wrong

C.Notmentioned

正确答案:A

答案解析:选A的依据是最后一段中的“... unlike adults, babies don\'t“turn off’their cerebral cortex while they sleep”。
