1、Meet Your MemoryMemory 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.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 blain until it is needed; and (3) retrieval (提取) refers to getting the material back out when it is needed.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.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.Paragraph 3 ______.【单选题】

2、Light Night, Dark StarsThousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, orartificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文学家) with the University Corporation forAtmospheric Research( UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they\'re lucky to see 150 stars.If you\'ve ever driven toward a big city at night and seen its glow from a great distance, you\'ve witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates (照亮) the night sky. This haze (朦胧) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult.Dust and particles of pollution factories and industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale."Hazy skies also make it far more difficult forastronomers to do their jobs.Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring (使变模糊) the faint (微弱的) light give off by distant stars. and if scientists can\'t locate these objects, they can\'t learn more about them.Light pollution doesn\'t only affect star visibility. It can harm wild life too. It\'s clear that artificial light can attract animals, making them go off course. There\'s increasing evidence, forexample, that migrating (迁徙) birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr. , a scientist at Clemson University in South Carolina, "When light occurs at night," he says, "it has a very disruptive (破坏性的) influence." Sometimes birds fly into lighted towers, high - rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year.On a clear night, people can see ______.【单选题】
A.150 stars
B.hundreds of stars
C.one thousand stars
D.more than 14,000 stars
正确答案:D
答案解析:本题难度不大,答案依据比较明显,在文章第一段第二句,这句话主要谈到,在晴朗的夜晚人们能看到14,000多颗星星,回来看选项,D项符合原文句意,是答案。

7、Black HolesMost scientists agree that black holes exist but are nearly impossible to locate. A black hole in the universe is not a solid object, like a planet, but it is shaped like a sphere (球体). Astronomers (天文学家) think that at the center of a black hole there is a single point in space with infinite (无限的) density (稠密).This single point is called a singularity (奇点). If the singularity theory is correct, it means that when a massive star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point. Anything that crosses the black hole is pulled in by its great gravity.Although black holes do exist, they are difficult to observe. These are the reasons,?No light oranything else comes out of black holes. As a result, they are invisible to a telescope.?In astronomical terms, black holes are truly. Forexample, a black hole formed by the collapse of a giant star would have an event horizon (视界) only 18 miles across.?The nearest black holes would be dozens of light years away from Earth. One light year is about 6 trillion (万亿) miles. Even the most powerful telescopes could not pick out an object so small at such a great distance.In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still answers to be found, however, so black holes remain one of the mysteries of the universe. (2007年)The sun is the heaviest star in the universe.【单选题】

9、Shopping at Second - hand Clothing StoresWhen 33 year old Pete Barth was in college, shopping at second hand clothing stores was just something he did- "like changing the tires on his car." He looked at his budget and decided he could save a lot of money by shopping forclothes at thrift shops."Even new clothes are fairly disposable (用后即丢掉的) and wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes."Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons forshopping forsecond - hand clothing. Some people, like him, shop to save money. Some shop fora crazy - looking shirt. and some shop as a mean conserving energy and helping the environment.Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said that, forher, shopping at thrift shops is a way to help the environment."When my daughter was little, we looked at it as recycling," Akins said. "Also, why pay 30 dollars fora new coat when you can get another one fora lot less?"Akins said that the SA has shops all over the US- "some as big as department stores. All of the clothes are donated (捐赠), and when they have a surplus (盈余), they\'ll have" stuff a bag" specials, where customers can fill a grocery sack with clothes foronly 5 or10 dollars.Julia Slocum, 22, points out, however, that the huge amount of second - hand clothing in the US is the result of American wastefulness."I\'d say that second - hand stores are the result of our wasteful, materialistic culture," said Slocum, who works fora pro - conservation organization, the center of a New American Dream. "Thrift shops prevent that waste from going to landfills (垃圾填埋场). They give clothing a second life, provide cheaper clothing forthose who can\'t afford to buy new ones and generate (创造) income forcharities. They also provide a way forthe wealthy and middle classes to shed (摆脱) the guilt fortheir level of consumption.What does Akins do? ______【单选题】
A.She is a soldier.
B.She is an accountant.
C.She is a saleswoman.
D.She is a road sweeper.
正确答案:B
答案解析:本题难度不大,答案依据不难找到。带着题干信息到文章定位,认真阅读文章第四段。第四段第一句话谈到,Akins是旧货店的一名会计,所以答案是B。
10、The SmogForover a month, Indonesia was in crisis. Forest fires raged out of control as the country suffered its worst drought for50 years. Smoke from the fires mixed with sunlight and hot dry air to form a cloud of smog. This pollution quickly spread and within days it was hanging over neighboring countries including Malaysia, Singapore and Thailand. When the smoke combined with pollution from factories and cars, it soon became poisonous. Dangerous amounts of CO became trapped under the smog and pollution levels rose. People wheezed (喘息) and coughed as they left the house and their eyes watered immediately. The smog made it impossible to see across streets and whole cities disappeared as grey soot(烟灰) covered everything. In some areas, water was hosed (用胶管浇) from high-rise city buildings to try and break up the smog. Finally, heavy rains, which came in November. Put out the fires and clear the air. But the environmental costs and health problems will remain. Many people from South-Eastern Asian cities already suffer from breathing huge amounts of car exhaust fumes and factory pollution Breathing problems could well increase and many non-sufferers may have difficulties forthe first time. Wildlife has suffered too. In lowland forests, elephants, deer, and tigers have been driven out of their homes by smog. But smog is not just an Asian problem. In fact. was world was first used in London in 1905 to describe the mixture of smoke and thick fog. Fog often hung over the capital. Sometimes the smog was so thick and poisonous that people were killed by breathing problems orin accidents. About 4, 000 Londoners died within five days as a result of thick smog in 1952. The forest animals haven\'t been affected by the smog. 【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:B
答案解析:题句的意思是“森林里的动物未曾受到烟雾的影响”。文中第4段最后一句提到一些动物由于烟雾逃出了森林。题句意思与原文有出入,故选B。
