1、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 3 ______【单选题】

2、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】

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 _____ 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】

A.put

B.keep

C.remove

D.study

正确答案:B

答案解析:本题难度不大，依据上下文逻辑，文章此处要用“保存”的意思，答案是B。

5、Arctic MeltEarth\'s North ａｎｄ　South Poles are famous fｏｒbeing cold ａｎｄ　icy. Last year, however, the amount of ice in the Arctic Ocean fell to a record low. Normally, ice builds in Arctic waters around the North Pole each winter ａｎｄ　shrinks 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 skimpiest levels yet. 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 scientists concerned. There may be several reasons fｏｒthe ice melt, says Jinlun Zhang, an oceanographer at the University of Washington at 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 3.5℃ warmer than average ａｎｄ　1.5℃ warmer than the previous record high. 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 measured just 50 centimeters by season\'s end. The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cover from above, says Donald K. Perovich, a geophysicist at the U. S. Army Cold Regions Research ａｎｄ　Engineering Laboratory in Hanover, N. H. Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover. What can be a possible title fｏｒthe passage?【单选题】

A.What are scientists looking fｏｒin the Arctic Ocean?

B.What are scientists doing in the Arctic Ocean?

C.Why are scientists worrying about the Arctic Ocean?

D.Why are scientists interested in the Arctic Ocean?

正确答案:C

答案解析:本文讲述了科学家们担心气温上升、冰川融化，最后一句话体现了主旨，所以选C。

6、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】

8、Sharing SilenceDeaf teenagers Orlando Chavez ａｎｄ　German Resendiz have been friends since kindergarten (幼儿园). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak ａｎｄ　hear.Orlando lost his hearing at the age of one. German was born deaf, ａｎｄ　his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kinder garten."We were in a special class with about 25 other deaf kids," German remembered. "Before then, I didn\'t know I was deaf ａｎｄ　I was different.""Being young ａｎｄ　deaf in regular classes was very hard," signs Orlando. "The other kids didn\'t understａｎｄ　us ａｎｄ　we didn\'t understａｎｄ　them. But we\'ve all grown up together, ａｎｄ　today, I\'m popular because I\'m deaf. Kids try to communicate with me."Some things are very difficult fｏｒthe two boys. "We can\'t talk on the phone, so if we need help, we can\'t call an emergency service," German signs. "ａｎｄ　we can\'t ｏｒｃｅｒfood in a drive - thru."Despite of their difficulties, the two boys have found work putting food in bags at a local supermarket.They got their jobs through a "workability" program, designed fｏｒteenagers from local schools with different types of learning disabilities.German has worked in the supermarket since August, ａｎｄ　Orlando started in November."The other people who work here nave been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we\'ve learned a lot ａｎｄ　we\'re getting better."The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute fｏｒthe Deaf in New York.According to the passage, the difficulty fｏｒOrlando ａｎｄ　German is that ______.【单选题】

9、Cell Phone Lets Your Secret OutYour cell phone holds secrets about you. Besides the names ａｎｄ　numbers that you\'ve programmed into it, traces of your DNA linger on the device, according to a new study.DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you- because you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, ｏｒhair left behind at the scene of a crime. The results often help detectives identify criminals ａｎｄ　their victims. Your cell phone can reveal more about you than you might think.Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone ａｎｄ　later dropped the device. This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved. So she ａｎｄ　colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs to collect invisible traces of the users from two parts of the phone: the outside, where the user holds it, ａｎｄ　the speaker, which is placed at the user\'s ear.The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back fｏｒanother week. Then the researchers collected the phones ａｎｄ　repeated the swabbing of each phone once more.The scientists discovered DNA that belonged to the phone\'s speaker on each of the phones. Better samples were collected from the outside of each phone, those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won\'t remove all traces of evidence from a criminal\'s device. So cell phones can now be added to the ______ of clues that can clinch a crime scene investigation.【单选题】

A.explanation

B.discovery

C.book

D.list

正确答案:D

答案解析:根据上下文的理解，应该选择list，其他三个选项与句子的意思不符。

10、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which _____ in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight ｏｒshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.operated

B.occurred

C.opened

D.offered

正确答案:B

答案解析:本题有一定难度，考查词义辨析，但干扰项干扰不大。可以先看选项得到信息提示。文章此处是说“……发生在1983年的南极洲”，显然，答案是B。
