He had an extremely luxurious room【C5】______himself. The room was air-conditioned—【C6】______a trace of the excessive heat he had feared. He【C7】______food and a smiling waitress immediately【C8】______with a delicious banquet. He felt【C9】______drinking and a large choice of wines was in front of him【C10】______.

on to supporting the bird they must act as its engine, rowing it through the air. Even so the wing outline or a bird conforms to the same aerodynamic principles as those eventually discovered by people when designing airplanes, and if you know how different kinds of aircraft perform, you can predict the flight capabilities of similarly shaped birds. Short, stubby wings enable a tanager and other forest-living to swerve and dodge at speed through the undergrowth, just as they helped the fighter planes of the Second World War to make tight turns and acrobatic maneuvers in a dog-fight. More modern fighters achieve greater speeds by sweeping back their wings while in flight, just as peregrines do when they go into a 130kph dive, swooping to a kill. Championship gliders have long, thin wings so that, having gained height in a thermal up-current they can soar gently down for hours and an albatross, the largest of flying birds, with a similar wing shape and a span of 3 meters, can patrol the ocean for hours in the same way without a single wing beat. Vultures and hawks circle at very slow speeds supported by a thermal and they have the broad rectangular wings that very slow-flying aircraft have. People have not been able to adapt wings to provide hovering flight. That has only been achieved with the whirling, horizontal blades of a helicopter or the downward-pointing engines of a vertical landing jet. Hummingbirds have paralleled even this. They tilt their bodies so that they are almost upright and then beat their wings as fast as 80 times a second producing a similar downdraft of air. So the hummingbird can hover and even fly backwards.

Which of the following is NOT true according to the passage?

A．Bird wings have to support the bird.

B．Bird wings must act as the bird"s engine.

C．Airplane"s wings must act as the airplane"s engine.

D．Similar wing shapes in aircraft and birds produce similar flight capabilities.

n that it concerns animals in their normal activities and therefore,if we wish,we can assess the possible dangers and advantages in our own behavioral roots. Ethnology also is interesting methodologically because it combines in new ways very scrupulous field observations with experimentation in laboratories. The field workers have had some handicaps in winning respect for themselves. For a long time they were considered as little better than amateur animal-watchers—certainly not scientists,since their facts were not gained by experimental procedures:they could not conform. to the hard-and-fast rule that a problem set up and solved by one scientist must be tested by other scientists, under identical conditions and reaching identical results. Of course many situations in the lives of animals simply cannot be rehearsed and controlled in this way. The fall flocking of wild free birds cant be,or the roving animals over long distances, or even the details of spontaneous family relationships. Since these never can be reproduced in a laboratory, they are then not worth knowing about? The ethnologists who choose field work have got themselves out of this impasse by greatly refining, the techniques of observing. At the start of a project all the animals to be studied are live-trapped,marked individually,and released. Motion pictures,often in color, provide permanent records of their subsequent activities. Recording of the animals voices by electrical sound equipment is considered essential,and the most meticulous notes are kept of all that occurs. With this material other biologists,far from the scene,later can verify the reports. Moreover, two field observers often go out together,checking each others observations right there in the field. Ethnology, the word, is derived from the Greek ethos, meaning the characteristic traits or features which distinguish a group-any particular group of people or,in biology,a group of animals such as a species. Ethnologists have the intention of studying "the whole sequence of acts which constitute an animals behavior."ln abridged dictionaries ethnology is sometimes defined simply as "the objective study of animal behavior,"and ethnologists do emphasize their wish to eliminate myths.

In the first sentence, the word"laymen"means____.

A．people who stand aside

B．people who are not trained as biologists

C．people who are amateur biologists

D．people who love animals

ell. The exchanges themselves do no trading,they merely provide a place where prospective buyers and sellers can meet and conduct their business. Wall Street,although the best known,is not home of exchanges in the United States. There are the cotton exchanges in New Orleans and Chicago; the Mercantile Exchange which deals in many farm products in Chicago; and grain exchanges in many of the large cities of the Midwest. Some exchanges,like Chicago Board of Trade, provide market services for several kinds of products. These trading posts where products may be brought or sold are called commodity exchanges. The security exchanges,on the other hand,are meeting places where stocks and bonds are traded. Like the commodity exchanges,they help serve the economic life of the country. But when their operations get out of hand,they may become very dangerous. In 1929,the security exchange,or stock market,contributed to a crash-a sudden sharp decline in the value of securities. Many people lost fortunes; many corporations were bankrupted; many workers lost their jobs. The crash of 1929 has been attributed to many causes,among them wild and unwise speculation by many people and dishonest practices on the part of some business and of some members of the exchanges. Today,however,investing through security exchanges and trading on commodity exchanges has been made safer by regulations set up by the exchanges themselves and by regulations of the United States government. In 1922,the government instituted the Commodity Exchange Commission which operates through the Department of agriculture; and in 1934,the Securities Exchange Commission,to protect investors and the public against dishonest practices on the exchanges.

Security and commodity exchanges are meeting places for buyers and sellers of_____.

A．stocks

B．securities

C．products

D．all of the above

"Its the perfect blend of technology, learning and exercise," says an educational psychologist. Wild Planet has【C5】______unveiled a younger version of Hyper Dash, for kids 3 to 5, 【C6】______Animal Scramble, which is due【C7】______stores in September. In【C8】______,the firm will soon release Hyper Jump. "Play and technology are【C9】______," says Claire Green of the nonprofit ParentsChoice Foundation.

在于实现，而是在于追求的过程。我们要时刻牢记，我们与生俱来的权力不是享受幸福而是追求幸福。幸福在于追求的本身，在于追求我们终生为之而努力并从中获得启迪的有意义的事情，也就是说在于追求的过程。对于一个民族的评价不是在于看它拥有什么或是想要拥有什么，而是看他想要并在追求什么。

g it like it is," or "letting it all hang out" My impression is that this overzealous devotion to speaking ones mind has more often led to hurt feelings and ruined relationships than to great joy and fulfillment. I think we generally agree that never expressing real feelings and repressing all less-than-lovely thoughts about each other【C2】______leads to constructive communication. Its a great relief to allow ourselves the luxury of acknowledging our human frailties and pursuing more honest relationships with others. But we need to strike a【C3】______between telling it all and telling nothing. Recently I received a letter from a mother who had been persuaded by her troubled twenty-five-year-old son to attend a weekend marathon with him. Under pressure from the group,her defenses collapsed and she heard herself telling her son for the first time that he had been an accident-that she hadnt been planning to have a child. He in【C4】______told her that he couldnt recall a single day in his childhood that he d been happy. "At that time," this woman wrote,"it seemed helpful. We cried and we made【C5】______; I thought telling the truth had been good for us. But the trouble is.it wasnt the whole truth. By the time Tommy was born I did want him,and at【C6】______he was happy. Ever since that day,weve both been haunted by some terrible feelings we shared. " I must admit that Ive come to the conclusion that some things are better left unsaid. Honesty is a fine policy as【C7】______as we know what the truth really is-but most of the time we dont Its a fine goal to encourage children to express their real feelings. And many marriages have been saved by an open confrontation of deep and painful misunderstandings. But we need a new sense of balance. Disclosure is not a panacea for every problem【C8】______even an end in itself. Its useful and freeing under some circumstances and terribly hurtful and damaging under others. Its a good idea,I think,to【C9】______your tongue for ten or fifteen minutes before saying whats【C10】______your mind. Try to decide whether its going to open up new and better avenues of communication or leave wounds that may never heal.

lescence. Perhaps there had also been a middle-aged crisis. But for the rest of adult life he had taken himself for【C1】______.with his capabilities and failings. Now,when he looks in the mirror,he asks himself, "Is this really me? "—or he avoids the mirror out of distress at【C2】______it reveals, those bags and wrinkles. In his new makeup he is【C3】______upon to play a new role in a play that must be improvised. Andre Gibe .that longlived man of letters,wrote in his journal, "My heart has remained so young that I have the continual feeling of playing a part,the part of the 70-year-old that I certainly am;and the infirmities and weaknesses that remind me of my acre act like a prompter,reminding me of my lines when I tend to stray. Then,like the good actor I want to【C4】______,go back into my role,and I pride【C5】______on playing it well." In his new role the old person will find that he is tempted by new vices,that he receives new compensations(not so widely known)and that he may possibly achieve new virtues. Chief among these is the heroic or merely obstinate refusal to surrender in the【C6】______of time. One admires the ships that go down with all flags【C7】______and the captain on the bridge. Among the vices of age are avarice,untidiness,and vanity,which last takes the form. of a craving to be loved or simply admired. Avarice is the worst of those three. Why do so many old persons,men and women【C8】______.insist on hoarding money when they have no prospect of using it and even when they have no heirs? They eat the cheapest food,buy no clothes,and live in a single room when they could afford better lodging. It may be that they regard money as a form. of power:there is a comfort in watching it accumulate while other powers are dwindling【C9】______. How often we read of an old person found dead in a hovel,on a mattress partly stuffed【C10】______bankbooks and stock certificates? The bankbook syndrome,we call it in our family,which has never succumbed.

lty: some planners believe in【C2】______transport system;others believe in making it possible for citizens to move【C3】______in private cars. There are several ways of【C4】______a public transport system. Sometimes it is built under the ground,sometimes it is on the【C5】______,and sometimes it is even above ground level, 【C6】______in parts of New York and more crime and Tokyo for example. In most cases, of course,it is a【C7】______of some or all of these elements. The【C8】______of the city centers has also been a problem in the last 30 years. The hearts of many cities have become poorer and poorer,【C9】______more and more crime and violence,【C10】______the people who can afford to have moved out to the【C11】______. This is the opposite of the situation 100 years a-go,【C12】______wealthypeoplelivedinthecenter, and the poor lived【C13】______the outskirts of the city. Ecological problems also【C14】______, as factories and cars pollute the air.tree are cut down to make【C15】______for urban clearways,and crowded conditions cause garbage to【C16】______in the streets. In order to solve these problems, some planners believe we should limit the size of our cities,perhaps by restricting population,or perhaps by offering【C17】______jobs in the provinces. Others believe that cities cannot be limited in size and that the problems must be solved in a【C18】______of ways—by creating green areas,building【C19】______houses for everybody,stopping factory pollution.【C20】______motor transport, and so on.
