根据材料请回答 36~40

Look After Your Voice

Often speakers at a meeting experience dry mouths and ask for a glass of water.You can solve the problem by activating the saliva(唾液)in your mouth.First gently bite the edges of your tongue with your teeth.Or, press your entire tongue to the bottom of your mouth and hold it there until the saliva flows.Or you can imagine that you are slicing a big juicy lemon and sucking the juice.

Before you begin your talk, be kind to your voice.Avoid milk or creamy drinks which coat your throat.Keep your throat wet by drinking a little sweetened warm tea or diluted (冲淡的) fruit juice.

If you sense that you are losing your voice, stop talking completely.Save your voice for your speech.You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice.If you need to see a doctor, perhaps you can get some advice from a professional singer.In the meantime, do not even talk in a low voice.

What about drinking alcohol to wet your throat? I advice you not to touch alcohol be-fore speaking.The problem with alcohol is that one drink gives you a little confidence.

The second drink gives you even more confidence.Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work to-get her properly.Save the alcohol until after you finish speaking.

Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a lifetime.Of course you can.Goethe, who lived before indoor skating rinks(滑冰场)or swimming pools, said, "We learn to skate in the summer and swim in the win-ter".Take this message to heart and give yourself time to develop your new habits.If you are willing to change, you will soon be able to say that you will never forget these tech-niques because they became a part of your body.

第 36 题 All the following are mentioned in the passage about how to solve the problem of dry mouths EXCEPT__________.

A.to bite the edges of your tongue

B.to ask for a glass of water

C.to imagine you are having a sour fruit

D.to take cool milk

听力原文: People in Poland take their pleasure seriously. They like to have an aim even wh
en spending the time which is entirely their own. During the summer, people start work very early in the morning so that they can finish early and enjoy a leisurely afternoon. It is difficult to imagine Polish people going aimlessly for a walk in the country, though they might go to pick wild fruit, to visit a place of historical importance or to walk 20km as a training exercise. They are often admired for their immense enjoyment of the arts. All parks are beautifully eared and are for the use and enjoyment of the people. Quite ordinary people will talk with obvious delight about concerts. There is nearly always a crowd at the door of the theatre, asking for returned tickets. People in Poland now have far more leisure time and more money than ever before. It is therefore possible to spend the weekends in many new ways. Many people now have over 20 days holiday a year. This provides an opportunity for holidays in the country or at the seaside.

To spend their leisure time, Polish people ______.

A.often go for walks

B.usually have a specific purpose in mind

C.prefer the seaside

D.seldom make plans in advance

Research on animal intelligence always makes me wonder just how smart humans are. 1 the fr

Intelligence, it 5 out, is a high-priced option. It takes more upkeep, burns more fuel and is slow 6 the starting line because it depends on learning — a gradual 7 — instead of instinct. Plenty of other species are able to learn, and one of the things they’ve apparently learned is when to 8 .

Is there an adaptive value to 9 intelligence? That’s the question behind this new research. I like it. Instead of casting a wistful glance 10 at all the species we’ve left in the dust I.Q.-wise, it implicitly asks what the real 11 of our own intelligence might be. This is 12 the mind of every animal I’ve ever met.

Research on animal intelligence also makes me wonder what experiments animals would 13 on humans if they had the chance. Every cat with an owner, 14 , is running a small-scale study in operant conditioning. we believe that 15 animals ran the labs, they would test us to 16 the limits of our patience, our faithfulness, our memory for terrain. They would try to decide what intelligence in humans is really 17 , not merely how much of it there is. 18 , they would hope to study a 19 question: Are humans actually aware of the world they live in? 20 the results are inconclusive.

Is it possible that the ideas we have today about ownership and property rights have been
so universal in the human mind that it is truly as if they had sprung from the mind of God? By no means. The idea of owning and property emerged in the mists of unrecorded history. The ancient Jews, for one, had a very different outlook on property and ownership, viewing it as something much more temporary and tentative than we do.

The ideas we have in America about the private ownership of productive property as a natural and universal right of mankind, perhaps of divine origin, are by no means universal and must be viewed as an invention of man rather than an order of God. Of course, we are completely trained to accept the idea of ownership of the earth and its products, raw and transformed. It seems not at all strange; in fact, it is quite difficult to imagine a society without such arrangements. If someone, some individual, didn't own that plot of land, that house, that factory, that machine, that tower of wheat, how would we function? What would the rules be? Whom would we buy from and how would we sell?

It is important to acknowledge a significant difference between achieving ownership simply by taking or claiming property and owning what we tend to call the "fruit of labor". If I, alone or together with my family, work on the land and raise crops, or if I make something useful out of natural material, it seems reasonable and fair to claim that the crops or the objects belong to me or my family, are my property, at least in the sense that I have first claim on them. Hardly anyone would dispute that. In fact, some of the early radical workingmen's movements made (an ownership) claim on those very grounds. As industrial organization became more complex, however, such issues became vastly more intricate. It must be clear that in modern society the social heritage of knowledge and technology and the social organization of manufacture and exchange account for far more of the productivity of industry and the value of what is produced than can be accounted for by the labor of any number of individuals. Hardly any person can now point and say, "That--that right there--is the fruit of my labor." We can say, as a society, as a nation--as a world, really--that what is produced is the fruit of our labor, the product of the whole society as a collectivity.

We have to recognize that the right of private individual ownership of property is man-made and constantly dependent on the extent to which those without property believe that the owner can make his claim stick.

According to the text, the concept of ownership probably

A.resulted from the unrecognized ancient history.

B.stemmed from the remote prehistoric times.

C.arose from the generous blessing of the Creator.

D.originated from the undetected distant periods.

根据材料请回答 16~22 题

The U.S.food supply is the most varied and abundant in the world.Americans spend a smaller share of their disposable income(可支配收入)on food than citizens of any other country and choose from an average of 50,000 different food products on a typical outing to the supermarket.In 1994, the fowl supply provided an estimated 3, 800 calories (卡路里) per person per day, enough to supply every American with more than one and a half times their average daily energy needs.Given this abundance, few of the Nations resources have traditionally been devoted to measuring or reducing food waste.

In recent years, growing concern about hunger, resource conservation, and the envi-ronmental and economic costs associated with food waste have raised public awareness of food loss.This in turn has accelerated public and private efforts to make better use of a-vailable food supplies by recovering safe and nutritious (有营养的)food that would other-wise be wasted.

Of course, not all food that is lost is suitable for consumption.Some losses - like the condemnation of diseased animals at the slaughtering house (屠宰场), or the discard of rotten fruit from the produce shelf at the supermarket are necessary to ensure the safety and health of the U.S.food supply.Such foods are not recoverable for human, use.

Likewise, plate fragments are appropriately discarded at eating establishments out of health considerations.In addition, not all food that is 10st is economically recoverable.Food recovery efforts are often limited by financial restraint.s that make it difficult-to match recovered food with potential recipients.

Nevertheless, large quantities of healthy, edible food are lost at every stage of the marketing system.Example of such losses include meats, bread, and other foods prepared by a restaurant or hotel but never served and the discard of defected or over-ripe produce, which may be difficult to sell out for some reasons, but are otherwise nutritious and safe.

第 16 题 The problem in America that the author is talking about in this passage is large a-mounts of food are lost in American.

A.Right

B.Wrong

C.Not mentioned

The picnics, speeches, and parades of today's Labor Day were all part of the first celebra
tion, held in New York City in 1882. Its promoter was an Irish-American labor leader named Peter J. MeGuire. A carpenter by trade, McGuire had worked since the age of eleven, and in 1882 was president of the United Brotherhood of Carpenters and Joiners(UBCJ). Approaching the City's Central Labor Union that summer, he proposed a holiday that would applaud the industrial spirit- "the great vital force of every nation, "On September 5 his suggestion bore fruit ,as an estimated 10, 000 workers, many of them ignoring their bosses' warnings, left work to march from Union Square up Fifth Avenue to the 42nd Street. The event gained national attention, and by 1893 thirty states had made Labor Day an annual holiday.

The quick adoption of the scheme may have indicated less about the state lawmakers' respect for working people than about a fear of risking their anger. In the 1880s the United States was a land sharply divided between the immensely wealthy and the very poor. Henry George was accurate in describing the era as one of" progress and poverty. "In a society, in which factory owners rode in private Pullmans while ten-year-olds slaved in the mines, strong anti-capitalist feeling ran high. Demands for fundamental change were common throughout the labor press. With socialists demanding an end to" wage slavery" and anarchists singing the praises of the virtues of dynamite, middle of-the-roarers like Samuel Gompers and McGuire seemed attractively mild by comparison. One can imagine practical capitalists seeing Labor Day as a bargain: a one-day party certainly cost them less than paying their workers decent wages.

Judging from the passage, McGuire was ______.

A.a moderate labor leader

B.an extreme-anarchist in the labor movement

C.a devoted socialist fighting against exploitation of man by man

D.a firm anti-capitalist demanding the elimination of wage slavery
