Cloze1In the 21st century, clouds and stormy weather no longer automatically bring operations to a halt or force a change in targets（目标）. Technologies such as the Global Positioning System now allow cruise missiles（巡航导弹) and other smart weapons to home in on（瞄准并飞速接近）their targets. But the weather still is a factor that must be reckoned with，especially with precision—guided weapons that must be highly accurate （高度精确)to be effective。

Fortunately，the ability to obtain weather forecasts will get better. In the next few years, remote weather sensors（传感器）will grow rapidly on unmanned (无人的)vehicles. This will create a network of observing platforms that will give commanders an instant overview of weather in the battle zone（战场）。

In some areas you’ll have direct delivery of weather information straight from the computes to black boxes in aircraft and other vehicles。

四级15选10填空练习Passage 1Questions 47 to 56 are based on the following passage.Perhaps like most Americans you have some extra pounds to 47 . You may even have tried a fad diet or two, but found yourself right back where you started. The key to weight loss is regular 48 activity. And surprisingly, you don’t have to give up eating or make the gym your second home to see long-term, 49 effects.You body needs a certain amount of energy to maintain basic 50 such as breathing, blood circulation and digestion. The energy required to keep your organs functioning is referred to as the resting or basal metabolic rate.Any time you are active, 51 energy is required. It is obtained from glycogen and fat stored in the blood, liver, and muscles. The key to losing weight is to draw on the fat rather than on the carbohydrate reserves.Which of the two energy sources you use depends on the intensity and 52 of your activity. The higher the intensity, the more your body will pull from the stored carbohydrates. The lower the intensity, the more your body will 53 on fat as its fuel.Aerobic exercise is most 54 for weight loss. When you perform aerobic activities you 55 contract large muscle groups such as your legs and arms. Walking, running, rollerblading, swimming, dancing, and jumping jacks are all forms of aerobic activity.Surprisingly, if your aerobic activity is low to moderately intense and of long duration, you will burn more fat than if you had 56 in a short burst of high-intensity exercise. In short, a brisk 30-minute walk will burn fat while a 100-yard sprint will burn glycogen.[A] positive [B] additional [C] duration [D] effective[E] shed [F] physical [G] food [H] functions[I] participated [J] rely [K] cut [L] repeatedly[M] uses [N] little [O] obviousPassage 2Questions 47 to 56 are based on the following passage.The comparatively treeless plains of North Africa have suffered a progressive drying up, both 47 and man-made, but the region was 48 so rich in fertile soil that the district we now know as the Libyan Desert was, in the old days, part of the granary (粮仓) of the Roman Empire, and the centre of the Sahara 49 a busy trading population for a long period. That was when there were 50 in plenty and the fields were the traditional “fields of the woods” —clearings in the forest—and therefore always tree 51 .It is the trees that lift the water and send 52 into the air so that it may fall as dew or rain further on. Trees reduce the speed of the wind, and provide shelter and shade; the roots 53 minerals in the soil and these are carried to the leaves which, when they have fulfilled their function, return to the earth, giving the soil the combination of minerals that plants require.But through the ages Africa has been 54 . Successive invaders have felled the forest to provide grazing lands for their flocks and herds. With the removal of the essential tree cover, the water 55 was broken, the earth became feverish and sick, and in course of time was unable to support those who had broken the 56 of life by removing the earth’s green mantle—the trees.A) moisture B) cycle C) water D) rhythmE) contain F) trap G) once H) surroundedI) fed J) exploited K) social L) naturalM) forest N) usually O) treesPassage 3Questions 47 to 56 are based on the following passage.Rock and roll is a genre of popular music that evolved in the United States in the late 1940s and early 1950s. Its 47 lie mainly in blues, rhythm and blues, country, folk, gospel, and jazz. The style subsequently spread to the rest of the world and developed further, leading ultimately to 48 rock music.The term “rock and roll” now covers at least two different meanings, both in common usage. The American Heritage Dictionary and the Merriam-Webster Dictionary both 49 rock and roll as synonymous with rock music.50 , defines the term as referring specifically to the music of the 1950s.Classic rock and roll is 51 played with one or two electric guitars, a string bass or an electric bass guitar, and a drum kit. In the 52 rock and roll styles of the late 1940s, either the piano or saxophone was often the lead instrument, but these were generally 53 or supplemented by the guitar in the middle to late 1950s.The massive popularity and eventual worldwide view of rock and roll gave it a 54 social impact. Far beyond simply a musical style, rock and roll, as seen in movies and in the new medium of television, 55 lifestyles, fashion, attitudes, and language. It went on to spawn various sub-genres, often without the initially 56 backbeat, that are now more commonly called simply “rock music” or “rock”.A) define B) characteristic C) unique D) rootsE) usually F) Basically G) earliest H) influencedI) followed J) modern K) explanation L) ConverselyM) replaced N) prepare O) seldomPassage 4Questions 47 to 56 are based on the following passage.There’s no question that the Earth is getting hotter. The real questions are: How much of the warming is our fault, and are we 47 to slow the devastation by controlling our insatiable 48 for fossil fuels?Global warming can seem too 49 to worry about, or too uncertain—something projected by the same computer 50 that often can’t get next week’s weather right. On a raw winter day you might think tha t a few degrees of warming wouldn’t be such a bad thing anyway. And no doubt about it: Warnings about 51change can sound like an environmentalist scare tactic, meant to force us out of our cars and restrict our lifestyles.Comforting thoughts, perhaps. Unfortunately, however, the Earth has some discomforting news. From Alaska to the snowy peaks of the Andes the world is heating up right now, and fast. Globally, the 52 is up 1°F over the past century, but some of the coldest, most remote spots have warmed much more. The results aren’t pretty. Ice is 53, rivers are running dry, and coasts are 54, threatening communities.The 55 are happening largely out of sight. But they shouldn’t be out of mind, because they are omens of what’s in store for the 56 of the planet.[A]remote [B]techniques [C]consisting [D]rest[E]willing [F]climate [G]skill [H]appetite[I]melting [J]vanishing [K]eroding [L]temperature[M]curiosity [N]changes [O]skillfulPassage 5Questions 47 to 56 are based on the following passage.Shopping habits in the United States have changed greatly in the last quarter of the 20th century. Early in the 1900s most American towns and cities had a Main Street. Main Street was always the 47 of a town. This street was lined on the both sides with many 48 businesses. Here, shoppers walked into stores to look at all sorts of merchandise: clothing, furniture, hardware, groceries. In addition, some shops offered 49 . There shops included drugstores, restaurants, shoe repair stores, and barber or hairdressing shops. But in the 1950s, a change began to 50 place. Too many automobiles had crowded into Main Street while too few parking places were 51 to shoppers. Because the streets were crowded, merchants began to look with interest at the open spaces outside the city limits. Open space is what their car driving customers 52 . And open space is what they got when the first shopping centre was built. Shopping centers, or rather malls, 53 as a collection of small new stores away from crowded city centers. Attracted by hundreds of free parking space, customers were drawn away from 54 areas to outlying malls. And the growing 55 of shopping centers led in turn to the building of bigger and better stocked stores. By the late 1970s, many shopping malls had almost developed into small cities themselves. In addition to providing the 56 of the stop shopping, malls were transformed into landscaped parks, with benches, fountains, and outdoor entertainment.[A]designed [B]take [C]heart [D]needed[E]though [F]convenience [G]services [H]fame[I]various [J]popularity [K]cosmetics [L]started[M]downtown [N]available [O]cheapnessPassage 6Questions 47 to 56 are based on the following passage.Have you ever been afraid to talk back when you were treated ____47 ___? Have you ever bought something just because the salesman talked you into it? Are you afraid to ask someone for a date.Many people are afraid to assert(表现)themselves. Dr. Alberti thinks it's because their self-respect is low. "Our whole ____48 ___ is designed to make people distrust themselves," says Alberti. "There's always '____49 ___' around-a parent, a teacher, a boss-who 'knows better'. These superiors often gain when they chip(削弱) away at your self-image."But Alberti and other scientists are doing something to help people ____50 ___ themselves. They ____51 ___ "assertiveness training" courses-At for short. In the AT courses people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be more ____52 ___ without hurting other people.In one way. learning to speak out is to ____53 ___ fear. A group taking a course will help the timid person to lose his fear. But AT uses an even stronger ____54 ___-the need to share. The timid person speaks out in the group because he wants to tell how he feels.Whether or not you speak up for yourself depends on your self-image. If someone you face is more "important" than you, you may feel less of a person. You start to ____55 ___ your own good sense.You go by the other person's ____56___ . But, why should you? AT says you can get to feel good about yourself. And once you do, you can learn to speak out.[A] doubt [B] active [C] system [D] offer[E] unfairly [F] unfortunately [G] motive [H] image[I] peace [J] demand [K] ask [L] superior[M] overcome [N] confidence [O] roarPassage 7Questions 47 to 56 are based on the following passage.Perhaps like most Americans you have some extra pounds to 47 .

And the glasses also 49 the user to "label" items so that information can be used later on. The wearer could walk around an office or a factory identifying certain 50 by pointing at them. Objects indicated are then given a 51 label on a screen inside the glasses that the user then fills in.It could be used in 52 plants by mechanics looking to identify machine parts or by electricians wiring a 53 device.A spokesman for the project said: "A car mechanic for 54 could find at a glance where a part on a certain car model is so that it can be identified and repaired. For the motorist the system could 55 accident black spots or dangers on the road."In other cases the glasses could be worn by people going on a guided tour, 56 points of interest or by people looking at panoramas where all the sites could be identified.[A] allow [B] instance [C] blank [D] industrial[E] frustrating [F] items [G] indicating [H] highlight[I] user [J] complicated [K] white [L] annoying[M] successful [N] articles [O] simplePassage 9Questions 47 to 56 are based on the following passageA sunflower is a sunflower.

When you have finished with your mobile phone you will be able to 49 it in the garden or a plant pot and wait for it to flower.50 , a biodegradable (生物可降解的)mobile phone was introduced by scientists. It is hoped that the new type of phone will encourage 51 to recycle.Scientists have come up with a new material over the last five years. It looks like any other 52 and can be hard or soft. and able to change shape. Overtime it can also break down into the soil without giving out any toxic 53 . British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it 54 nitrates(硝酸盐). These feed the seed and help the flower grow.Engineers have designed a small 55 window to hold the seed. They have made sure it only grows when the phone is thrown away."We've only put sunflower seeds into the covers so far. But we are working with plant 56 to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.[A] Recently [B] consumers [C] chemicals [D] environment[E] combine [F] transparent [G] buy [H] companion[I] experts [J] forms [K] bury [L] paper[M] paper [N] plastic [O] UsuallyPassage 10Questions 47 to 56 are based on the following passage.Blue is the world's favorite color.

But the U.S. has more than 100 million existing homes, and it would be __47__ wasteful to tear them all down and __48__ them with greener versions. An enormous amount of energy and resources went into the construction of those houses. And it would take an average of 65 years for the __49__ carbon emissions from a new energy-efficient home to make up for the resources lost by destroying an old one. So in the broadest __50__, the greenest home is the one that has already been built. But at the same time, nearly half of U. S. carbon emissions come from heating, cooling and __51__ our homes, offices and other buildings. "You can't deal with climate change without dealing with existing buildings," says Richard Moe, the president of the National Trust.With some __52__, the oldest homes tend to be the least energy-efficient. Houses built before 1939 use about 50% more energy per square foot than those built after 2000, mainly due to the tiny cracks and gaps that __53__ over time and let inmore outside air.Fortunately, there are a __54__ number of relatively simple changes that can green older homes, from __55__ ones like Lincoln's Cottage to your own postwar home. And efficiency upgrades (升级) can save more than just the earth; they can help __56__ property owners from rising power costs.注意：此部分试题请在答题卡2上作答。

A traveler visiting the hut in the middle of the dark time and perhaps in bad weather, his feet, hands and face bitten by the frost, will have his difficulties doubled if the wood he left has been used up by others and he had nothing with which to19 a fire.Ten or more years ago there were enough hunters to look after most of the huts, but now many buildings have become useless because there is no one to repair them and because of 20A. worseB. peculiarC. laidD. lightE. generallyF. orderG. particularH. conventionsI. carelessness J．difference K. built L. fashionsM. searching N. ordinarily O. resultUnit SevenPassage 2Most of us trade money for entertainment.

There is 11 a type of music called "the blue", a low, mournful, sad sound to 12 these universal human feelings.Depression is another name for this mood. Feeling depressed is a normal and natural 13 to experiences of loss, failure, and undeserved bad luck. Indeed, it has been pointed out that without depression, we would 14 much of the world's great tragic literature, music, and art.In some cases, however, depression becomes something more than just 15 feelings of blues or letdown. A large number of people suffer from what psychiatrists call "depressive illness. " Depressive illness is more 16 and lasts longer than common listless feelings. Sometimes a serious 17 of depression can begin with the loss of a loved one or a change of job. Many times, in very18 cases, there doesn't seem to be any circumstance serious enough to have caused the depression.Some psychiatrists suggest that the key feature in depression is change. The person becomes different from the way before the onset of his depression. He may even become the opposite of his usual self. There are many examples: the businessman who becomes a wanderer, the mother who wants to 19 her children and herself. Instead of seeking satisfaction and pleasure, the depressed person 20 it.A growing world population and the discoveries of science may 11 this pattern of distribution in the future. As men slowly learn to master diseases, control floods, prevent famines, and stop wars, fewer people die every year; and in 12 the population of the world is 13 increasing. In 1925 there were about 2,000 million people in the world; by the end of the century there may well be over 4,000 million.When numbers rise the 14 mouths must be fed. New lands must be I bought under cultivation, or land already farmed made to 15 larger crops. In some areas the accessible land is largely so intensively 16 that it will be difficult to make it provide more food. In some areas the population is so dense that the land is parceled out in units too 17 to allow for much improvement in farming methods. Were a larger part of this farming population drawn off into industrial occupations, the land might be farmed much more productively by modern methods.There is now a race for science, technology, and industry to keep the 18 of food rising faster than the number of people to be fed. New strains of crops are being developed which will thrive in 19 climates; irrigation and dry-farming methods bring poor lands under the plough, dams hold back the waters of great rivers to 20 water for the fields in all seasons and to provide electric power for new industries; industrial chemistryprovides fertilizers to suit particular soils; aero planes spray crops to destroy insects and many plant diseases.A. ensureB. violentlyC. alterD. harmfulE. cultivatedF. uniqueG. transplantedH. yieldI. consequenceJ. outputK. extraL. steadilyM. tinyN. unfavorableO. produceUnit TenPassage 2In the United States, it is not 11 to telephone someone very early in the morning. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11: 00 p. m. . If someone receives a call during sleeping hours, he 12 it's a matter of life and death. The time chosen for the call 13 its importance.In 14 life, time plays a very important part. In the U. S. A. , guests tend to feel they are not highly regarded if the 15 to a dinner party is extended only three or four days before the party date. But it is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in 16 because plans which are made for a date more than a week away tend to be forgotten. The meaning of time differs in different parts of the world. Thus, misunderstandings 17 between people from cultures that treat time differently.Promptness is valued 18 in American life, for example. If people are not prompt, they may be regarded as impolite or not fully responsible. In the U. S. no one would think of keeping a business 19 waiting for an hour, it would be too impolite.

But the environment must also have a 11 effect, wince if competition is important to the parents it is likely to become a major 12 in the lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools 13 the " win at all costs" moral standard and measure their success by sporting achievements. The current 14 for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being 15 keen to win can have dangerous consequences: remember that Pheidippides, the first marathon runner, dropped dead seconds after saying; "cheers, we conquer!"By far the worst form of competition in schools is the extreme 16 on examinations. It is a rare school that allows pupils to 17 on those things they do well. The merits of competition by examination are somewhat 18 , but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither 19 nor desirable that all A youngsters change into B's.

Once you are in habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body. Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often 12 to be. A certain amount of stress is 13 to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor 14 and ill health.The amount of stress a person can 15 depends very much on the individual. Some people are not afraid of stress, and such characters are 16 prime material for managerial responsibilities. Others lose heart at the first signs of 17 difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so 18 , but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued 19 to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot 20 stress from our lives(it would be unwise to do so even if we could) , we need to find ways to deal with it.A. cancelB. paceC. extremeD. automaticallyE. removeF. vitalG. performanceH. supposedI. rate J. exposure K. achievement L. unusualM obviously N withstand O harshUnit ThirteenPassage 2What is your favorite color? Do you like yellow, orange, red? If you do, you must be an optimist, a leader, an active person who 11 life, people and excitement. Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You 12 to be a pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference, as well as the effect that colors have on human beings. They tell us, among other 13 , that we do not choose our favorite color as we grow up—we are born with our preference. If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.Colors do 14 our moods—there is no doubt about it. A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is 15 .A black bridge over the Thames River, near London, used to be the 16 of more suicides than any other bridge in the area—until it was repainted green. The number of suicide attempts immediately fell 17 ; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.Light and 18 colors make people not only happier but more active.

In 1985, Regent Beryl Milburn produced a report blasting the University of Texas System administration for not 12 women. The University was rated among the lowest for the system. In a 1587 update, Milburn 13 and praised the progress that was made and called for even more 14One of the positive results from her study was a system-wide program to inform women of available administrative jobs.

"Women need to spend their energies and time doing scholarly activities that are important here at the University. " Spirduso said. "If they do that they will be 19 in this system.

They must act on the belief that all students can learn. They must recognize 13 differences in their students and adjust their practice 14 . They must know that their mission extends beyond developing the cognitive capacity of their students. They must be 15 with their students' self-concept, with their motivation, and with the development of character.Teachers must know the subjects they teach and how to teach them. They must 16 specialized knowledge of how to convey a subject to students. Teachers are responsible for managing and monitoring student learning. They must call on 17 methods to meet their goals, knowing and being able to 18 a variety of instructional skills. Teachers must think systematically about their practice and learn from experience, seeking the 19 of others and drawing on education research and scholarship to improve their practice.As members of learning communities, teachers contribute to school effectiveness by collaborating with other professionals.

But if you need up-to-the-minute data or have specialized needs, you may find a computerized database more useful, less expensive, and less time 11 .A database, a file of information on one subject or family of subjects, can be stored and 12 in a computer's memory. The speed of the computer then 13 you to recall any item in this file almost 14The three main types of databases are statistical, bibliographic, and full text. Statistical databases store 15 amounts of numerical data, such as wage and price indexes, census information, foreign 16 rates and bond prices. Bibliographic databases store references to and summaries of articles in periodicals and newspapers. Full-text databases offer the complex texts of such 17 as newspaper, magazine, and journal articles.Thousands of databases exist today, and their numbers are growing. Many companies have their in-house database, which is 18 to employees through computer terminals or microcomputers.

Disability is not just something that happens to other people: as we get older, many of us will become less 13 , hard of hearing or have failing eyesight. Disablement can take many forms and occur at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many 14 disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have a period of disability in the form of a mental illness. All are affected by people's attitude towards them.Disabled people face many 15 barriers. Next time you go shopping or to work or to visit friends, imagine how you would 16 if you could not get up steps, or on to buses and trains. How would you cope if you could not see where you were going or could not hear the traffic? But there are other barriers; 17 can be even harder to break down and ignorance 18 represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through, so it is important to 19 attention to these barriers and show that it is the individual person and their ability, not their disability, which 20A. inevitablyB. evaluationsC. estimatesD. manageE. aloneF. countsG. prejudiceH. physicalI. mobile J. indifferently K. withdraw L. progressiveM. regular N. accounts O. drawUnit EighteenPassage 2Social customs and ways of behaving change. Things which were considered impolite many years ago are now11 . Just a few years ago, it was 12 impolite behavior for a man to smoke on the street. No man who thought of himself as being a gentleman would make a 13 of himself by smoking when a lady was in a room. Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it 14 ? What about table manners? Should you use both hands when you are eating? Should you leave one in your lap, or on the table?The Americans and the British not only speak the same language but also 15 a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a woman or offer their seat to a woman, and so will most Americans. 16 is important both in England and in America. That is, if a dinner invitation is for 7 o'clock, the dinner guest either arrives 17 to that time or calls up to explain his 18The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable— 19 if they are your guests.

Despite 11 alarms, the country escaped any postwar depression and lived in a 12 of boom. An economic survey of the year 1955, a typical year of the 1950's, may be typical as 13 the rapid economic growth of the decade. The national output was 14 at 10 percent above that of 1954(1955 output was estimated at 392 billion dollars). The production of manufactures was about 40 percent more than it had 15 in the years immediately following World War I . The country's business spent about 30 billion dollars for new factories and machinery. National income 16 for spending was almost a third greater than it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day, or about twenty-five million dollars every hour, all round the 17 . Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them. Only agriculture 18 that it was not sharing in the boom. To some observers this was a sad reflection of the mid-1920's. As farmers' share of their products 19 , marketing costs rose. But there were, among the observers of the national economy, a few who were not as confident as the majority. Those few seemed to fear that the boom could not last long and wouldwill certainly be developed more than in the past.There are many reasons why we should 18 the production of sugar. Most important is that it is one of the most highly concentrated of energy foods.Thus sugar cane and beet produce an average of 7,000,000 calories per acre. In this way they have the advantage over potatoes which give only 4, 000, 000, while the 19 for wheat and beans is 2 ,000,000 each.

Today, computers are easy to come by and many people know how computer technology 11 . More importantly, the growing use of computer networks can multiply the violation of security, making large numbers of people more vulnerable than would be the case if they were using 12 , stand-alone computers.What's more, computer experts agree that—despite recent widespread publicity-computer viruses are 13 one of the many computer security problems facing the nation.The U. S. Defense Advanced Research Project Agency has requested that the Research Council's Science and Technology Board 14 the security problems posed by computer technology, see what 15 may already exist, review research efforts 16 at avoiding security problems in the future, and evaluate existing policies 17 to computer security. The study committee will examine the 18 of security for a broad spectrum of users, including the business, national security, and academic communities, as well as the 19 public.David.

The11 in these rings relates to the physical conditions which the tree experiences. Thus, trees grown in a 12 area and time each develop a pattern or configuration of their rings.This 13 was of little significance until Andrew E. Douglas began to study tree rings in Arizona in 1900. Using a technique called cross dating, he was able to employ tree rings to the study of archaeological sites and date the ruins with 14 . Some were as old as 6700 B. C. ! This study of tree rings is called dendrochronology.In time the cross dating was 15 by a carbon 14 process. This approach measured the amount of carbon 14 radiating from a piece of wood and 16 to determine the age of that wood. Further use of the carbon 14 technique has shown that the radiation process is more complex and less 17 than had been at first thought.The most 18 aspect of tree ring research is now called dendroclimatology. This 19 of the reconstruction of climates and climatic cycles and events from the evidence found in the tree rings.

Materials used for one purpose cannot at the same time be used for other purposes; if the quantity of an input is limited, the increased use of it in one manufacturing process must cause it to become less available for other uses.The cost of a product in 14 of money may not measure its true cost to society. The true cost of, say, the construction of a supersonic jet is the value of the schools and refrigerators that will never be built as a result. Every act of production uses up some of society's available resources; it means the foregoing of an opportunity to produce something else. In deciding how to use resources most effectively to 15 the wants of the community, this opportunity cost must 16 be taken into account.In a market 17 the price of a commodity and the quantity supplied depend on the cost of making it, and that cost, ultimately, is the cost of not making other goods. The market mechanism enforces this 18 . The cost of, say, a pair of shoes is the price of the leather, the labor, the fuel, and other elements used up in producing them.

Or is the bee just a machine, unable to do its mathematics and dance its language in any other way? To use Donald Griffin's term, does a bee have "awareness", or to use a 12 I like better, can a bee think and imagine?There is an experiment for this, or at least an 13 , made long ago by Karl Von Frisch and more recently 14 by James Gould at Princeton. Biologists who wish to study such things as bee navigation, language, and behavior in general have to 15 their bees to fly from the hive to one or another special place. To do this, they begin by placing a source of sugar very close to the hive so that the bees (considered by their trainers to be very dumb beasts) can learn what the game is about. Then, at regular intervals, the dish or whatever is moved 16 farther and farther from the hive, increasing about 25 percent at each move. Eventually, the 17 is being moved 100 feet or more at a jump, very far from the hive. Sooner or later, while this process is going on, the biologists 18 the dish of sugar will find the bees are out there waiting for them, 19where the 20 position had been planned.
