1、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.Light pollution occurs when ______.【单选题】
A.artificial lights illuminate the night sky
B.the moon lights up the night sky
C.too many stars are visible in the night sky
D.streetlights are turned off

3、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.Paragraph 4 ______【单选题】
A.Why do we forget things?
B.How do we measure memory?
C.What are the stages memory consists of?

4、Why Would They Falsely Confess?Why on earth would an innocent person falsely confess to committing a crime? To most people, it just doesn\'t seem logical. But it is logical, say experts, if you understand what can happen in a police interrogation room.Under the right conditions, people\'s minds are susceptible to influence, and the pressure put on suspects during police grilling is enormous. "It\'s a little like somebody\'s working on them with a dental drill," says Franklin Zimring, a law professorat the University of California at Berkeley. "The pressure is important to understand, because otherwise it\'s impossible to understand why someone would say he did something he didn\'t do. The answer is: to put an end to an uncomfortable situation that will continue until he does confess."Developmental psychologist Allison Redlich recently conducted a laboratory study to determine how likely people are to confess to things they didn\'t do. In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems. The researchers then intentionally crashed the computers and accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.Redlich\'s findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed. ______ Of the 15-to 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12-to 13-year-olds."There\'s no question that young people are more at risk," says Saul Kassin, a psychology professorat Williams College, who has done similar studies with similar results, "But adults are highly vulnerable too."Both Kassin and Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation-not hours of aggressive questioning-and still, most participants falsely confessed.Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation. "In some ways," says Kassin, "false confession becomes a rational decision."【单选题】

5、Will We Take Vacation in Spaces?When Mike Kelly first setout to build his own private space-ferry service, he figured his bread-and-butter business would be lofting (发射) satellites into high-Earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly, who runs Kelly Space & Technology out of San Bemardino, California. "I realized that real market is in space tourism."According to preliminary market surveys, there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington, Virginia, has taken more than 130 deposits fora two-hour, $98, 000 space tour tentatively and somewhat dubiously (可疑地) setto actorby 2005. Gene Meyers of the space Island Group says: "Space is the next exotic(风光奇特的) vacation spot. "This may all sound great, but there are a few hurdles (困难). Putting a simple satellite into orbit with no oxygen, life support orreturn trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. and that doesn\'t include the oust of insuring rich and possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entiregroupof entrepreneurs trying to corner (垄断) the space-tourism market have between them "just enough money to blow up one rocket."The U. S. space agency has plenty of money but zero interest in mailing space less expensive forthe little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that is inexpensive, safe and reliable. Kelly Space\'s prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in Redwood City, California, has a booster with rotors to make a helicopter-style return to Earth; Kistler Aero-space in Kirkland, Washington, is piecing together its versions from old Soviet engines, shuttle-style thermal protection tiles and an elaborate parachute system. The first passenger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can\'t be too prepared, fora trip to that galaxy far, far away. Forthose who are intent on joining the 100-mile high club, Hilton and Budget are plotting to build space hotels. Before the Russian spaceship Mir came down, some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space, and if you are thinking of staying in it, you may want to check the Michelin ratings before booking yourself a suite. It sounds great that soon there will be space residence, although it is still a tentative plan. 【单选题】
