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.Remembering involves getting the material back out when it is ______.【单选题】
A.short-term memory
B.relearning
C.needed
D.coded
E.recognition
F.slow forgetting rate
正确答案:C
答案解析:根据题干线索词getting the material back定位原文至第二段,该段只有一句话,但其后一部分提到retrieval (提取) refers to getting the material back out when it is needed. 这里retrieval与题干中的remembering意思相近,题干是对该部分的同义改写。由此推知,所需添加成分即为句中画线部分。C选项needed属于原文复现,故C为正确答案。
2、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack orstroke later in life and could prevent hundreds of thousands of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections and allergies and are less prone to obesity. British scientists have now shown that breastfeeding and slow growth in the first weeks and months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol and increasing their tendency to diabetes and obesity-the four main risk factors forstroke and heart attack." said ProfessorAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure and cholesterol later in life are greater than ______ adults can do to control the risk factors forcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack and strokes, each year, according to the World Health Organization. Lucas and his colleagues compared the health of 216 teenagers who as babies had either been breastfed orgiven different nutritional baby formulas\' They reported their findings in The Lancet medical journal. The teenagers who had been breastfed had a 14 percent lower ratio of bad to good cholesterol and lower concentrations of a protein that is a marker forcardiovascular disease risk. The researchers also found that regardless of the child\'s weight at birth, the faster the infants grew in the early weeks and months of life, the greater was their later risk of heart disease and stroke. The effect was the same forboth boys and girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【单选题】
A.which
B.that
C.something
D.anything
正确答案:D
答案解析:根据语法结构和句意判断D(任何事情)合适。
3、A Bad IdeaThink you can walk, drive, take phone calls, e - mail and listen to music at the same time 7 Well, New York\'s new law says you can\'t. _____. The law went into force last month, following research and a shocking number of accidents that involved people using electronic gadgets (小巧机械) when crossing the street.Who\'s to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."The young people are often considered the great multitaskers. However, an Oxford University research suggests this perception is open to question. Agroupof 18 to 21 years old and agroupof 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The youngergroupdid 10 percent better when not interrupted. But when both groups were interrupted by a phone call oran instant message, the oldergroupmatched the youngergroupin speed and accuracy.It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $ 650 billion a year. The estimate is based on surveys with office workers. The surveys conclude that 28 percent of the workers\' time was spent on interruptions and recovery time before they returned to their main tasks.【单选题】
A.Talking on a cell phone while driving brings you joy anyway.
B.The estimate is based on surveys with office workers.
C.The youngergroupdid 10 percent better when not interrupted.
D.However, an Oxford University research suggests this perception is open to question.
E.Scientists say that our multitasking (多任务处理) abilities are limited.
F.and you\'ll be fined $ 100 if you do so on a New York city street.
正确答案:F
答案解析:本题难度不是很大。可用排除法和代入法。本题的上文谈到纽约新的法律规定在走路开车时不能打电话,发邮件,听音乐,下文转到谈新法律发生效力时间,所以可以推断此处会继续跟着上文展开阐述,应该讲如果你做了会导致什么结果,回来看选项,把F代入文中,符合逻辑,答案是F。
4、Snow RangerThe two things, snow and mountains, which are needed fora ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain, often called "White Death. "It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937, 38 at Alta, Utah, in Wasatch National Forest. This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a majorski area. Thus, development of Alta and other majorski resorts in the west was dependent upon controlling the avalanche. The Forest Service setout to do it, and did with its corps of snow rangers. It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber. He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better. He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down. The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety forpeople on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, ortalks with the ski area\'s operatoras he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes. What is the primary duty of the snow ranger?【单选题】
A.To make sure ski area operators are following safety rules.
B.To predict and control avalanches in mountainous areas.
C.To check skis and repair them.
D.To forecast the weather.
正确答案:B
答案解析:A:确保滑雪场地的操作员遵守安全规则;B:预测和控制山区的雪崩;C:检查并修理雪橇;D:预测天气。依据常识和前一题判断B最合理。
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 (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.The word "builds" in paragraph 2 could be best replaced by ______【单选题】
A.establishes
B.expands
C.creates
D.constructs
正确答案:B
答案解析:本题难度不大,文章此处build的引申意义指“(冰层)加厚”,选项中expands是其近义解释,答案是B。
6、A lot of people could fall ill after drinking contaminated water.【单选题】
A.muddled
B.polluted
C.mixed
D.troubled
正确答案:B
答案解析:题干大意:很多人喝过受污染的水生病了。画线词contaminated是动词contaminate的过去分词,这里作形容词用,contaminated:受到污染的,故和polluted同义。muddled water和troubled water:混浊的水。mixed water:混合水。故答案选B。
7、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 color- changing material. It will turn red before a structure collapses orfalls apart.The secret behind the color- changing material is a particular type of molecule (分子). A molecule is agroupof atoms (原子) held together by chemical bonds. Molecules come in 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 color- changing molecule called a mechanophore (机械响应性聚合物) is about to break, it produces 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 color- changing polymers in their lab. The test results proved encouraging.There is a way to get rid of the red colorlight. When a bright light is shone on the mechanophore, the broken bond is fixed and the red colordisappears. Thus "self - healing" may be a problem forengineers. They need to use the color- changer in big construction projects that will be outside, under sunlight. and sunlight will make the mechanophore\'s warning system useless.Sottos and her fellow scientists still have _____ work to do before the color- changing molecules can be used outside the lab.【单选题】
A.a pair of
B.a type of
C.a lot of
D.a part of
正确答案:C
答案解析:本题难度不大,考查词义辨析。文章此处是说“Sottos和同事们还有很多工作要做”,答案是C。
8、The most pressing problem that any country faces is how to use its scarce natural resources. 【单选题】
A.puzzling
B.difficult
C.terrifying
D.urgent
正确答案:D
答案解析:puzzling:让人疑惑的、费解的、令人感到莫名其妙的;difficult:困难的、艰难的;terrifying:可怕的、极大的;urgent:急迫的、紧急的,和pressing意思相同。
9、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, orthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged ordestroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harborif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.A powerful hurricane may become the most destructive ______.【单选题】
A.different labels
B.window and glass doors
C.inland flooding
D.early warning
E.natural disaster
F.a constant speed
正确答案:E
答案解析:本题有一定难度,需要认真寻找答案依据,答案依据在文章第三段的倒数第二句:A powerful hurricane can kill more people and destroy more property than any other natural disaster。回来看选项,E项符合原文句意,是答案。
10、Don\'t Rely on Plankton to Save the PlanetEncouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron fora month. ______In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results."These are newer and better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."Butthe take-home message is the same. Ocean fertilization is not the answer to global warming."【单选题】
A.Its opponents argue, however, that it will stop global warming.
B.Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.
C.As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.
D.They found that 100 years later only between 2 and 13 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.
E."These are newer and better models,"
F.Ocean fertilization is not the answer to global warming.
正确答案:D
答案解析:代词they的指代(Jorge Sarmiento from Princeton and his colleagues)和句意上的承接。空白前句说Jorge Sarmiento和他的同事们研制出一个复杂的计算机模型来分析……因素的影响……,D接着说他们发现100年以后…(100年以后的结果只能通过模拟发现)。
