回答题：

Adaptation of Living Things

Certain animals and plants develop characteristics that help them cope with their environ-ment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter， in providing protection， and in producing and protecting the young. That results in the evolution of more and more organisms（生物体） that are better fitted to their environments.

Each living thing is adapted to its way of life in a general way， but each is adapted especially to its own distinct class. A plant， for example， depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals （无机物）. It depends upon its green leaves for using the sun"s energy to make food from inorganic chemicals. These are general .adaptations， common to most plants. In addition， there are special adaptations that only certain kinds of plants have.

Many animals have adaptations that help them escape from their enemies. Some are hidden by their body color or shape， and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the ability to remain completely still when an enemy is near.

Organisms have a great variety of ways of adapting. They may adapt in their structure， function， and genetics; in their development and production of the young; and in other respects. An organism may create its own environment， as do warm-blooded mammals （哺乳动物）， which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage， but sometimes an organism is so well adapted to a particular environment that if conditions change， it finds it difficult or impossible to readapt to the new conditions.

Some plants and animals develop superior characteristics so that they may 查看材料

A.help Others of their kind get food， shelter and other things needed

B.survive even in extremely severe conditions

C.become better adapted to the environments than others of their kind

D.result in the evolution and production of more intelligent organisms

阅读材料，回答题。

Washington Irving was America’s first man of letters to beknown internationally. His works were received enthusiastically both in Englandand in the United States. He was, in fact; one of the most successful writersof his time in the country, and at the same time winning the admiration offellow writers like Scott in Britain and Poe and Hawthorne in the UnitedStates. The respect in which he was held partly owing to the man himself, withhis warm friendliness, his good sense, his urbanity, his gay spirits, hisartistic integrity, his love of both the Old World and the New. Thackeray describedIrving as "a gentleman, who, though himself born in no very high sphere, wasmost finished, polished, witty; socially the equal of the most refinedEuropeans. " In England be was granted an honorary degree from Oxford anunusual honor for a citizen of a young, uncultured nation and he received themedal of the Royal Society of Literature. America made him ambassador to Spain.

Irving’s background provides little to explain his literaryachievements. A gifted but delicate child, he had little schooling. He studiedlaw, but without zeal, and never did practice seriously. He was immune to hisslrict Presbyterian home environment, frequenting both social gatherings and thetheater.

Intellectual Revolution

Culture is activity of thought, and receptiveness to beauty and humane feeling. Scraps of information have nothing to do with it. A merely well-informed man is the most useless51on God&39;s earth. What we should52at producing is men who possess both culture and expert knowledge in some special direction.Their expert knowledge will give them the ground to start53, and their culture will lead them as54as philosophy and as high as art. We have to remember that the valuable55development is self-development,and that it56takes place between the ages of sixteen and thirty. As to training, the most important part is given by mothers before the age of twelve.

In training a child to activity of thought, above all things we must beware of what I will call "inert ideas" -that is to say, ideas that are merely.57into the mind without being utilized, or tested, or thrown into fresh combinations. In the history of education, the most58phenomenon is that schools of learning, which at one epoch are alive with a craze for genius, in a59generation exhibit merely pedantry and routine. The reason is that they are overladen with inert ideas. Except at60intervals of intellectual motivation, education in the past has been radically 61with inert ideas. That is the reason why. 62clever women, who have seen much of the world, are in middle life so much the most cultured part of the community. They have been saved from this horrible63of inert ideas. Every intellectual revolution which has ever stirred humanity64 greatness has been a65protest against inert ideas.

Government Policies and Economy

While he was off on his l978 tour，Americans were becoming disgusted with their lot as all“emerging second—class nation”，Wilson says．They began to see that incentives had to be restored to the economy．For instance，the capital gains tax was cut，an extraordinary turn—about．If it had been predicted before he went away in May，he would have said it was simply inconceivable as inconceivable as the prospect of Resorts going up1，000 percent．

This momentous transformation in the U．S．should soon bring about a huge bull market． In the l940s and l950s，the last time price earning multiples were at these low levels，the investing public expected that there would be another great postwar depression．Instead，aRer the beginning of l953 it became apparent that there would not be one，and price-earnings multiples got so low this time that investors felt that the country was drifting into socialism．That drift，however，may be reversing direction．

Wilson believes that the bankruptcy of New York City means the discrediting of big government，that as a result there will be less government，and that things in general will go much better．From l980’s depressed levels the market could rise to twenty times doubled earnings or almost fivefold in five to seven years．Wilson believes that he’ll be worth hundreds of millions of dollars before it’s over．

From paragraph l，we can infer that Resorts is__________．查看材料

A.a company that involves many capital gains

B.a company that has little hope of rapid growth

C.a company that benefited from capital gains tax

D.a company that stimulates the economy

阅读材料，回答题：

Understanding Autism

1 Autism (孤独症) is a life-long developmental disability that prevents individuals from properly understanding what they see, hear, and otherwise sense. This results in severe problems of social relationships, communication, and behavior. Individuals with autism have to painstakingly (费力地) learn normal patterns of speech and communication, and appropriate ways to relate to people, objects, and events, in a similar manner to those who have had a stroke.

2 The cause of autism is still unknown. Some research suggests a physical problem affecting those parts of the brain that process language and information coming in from the senses. There may be some imbalance of certain chemicals in the brain. Genetic (遗传的 )factors may sometimes be involved. Autism may indeed result from a combination of several "causes"

3 Most people with mental retardation (智力迟钝)show relatively even skill development. Indi- viduals with autism, however, typically show uneven skill development, with deficits (欠缺)in cer- tain areasmmost frequently in their ability to communicate and relate to others--and distinct skills in other areas. It is important to distinguish, autism from mental retardation or other disorders,.&

since diagnostic (诊断的)confusion may lead to inappropriate and ineffective treatment tech- niques.

4 In general, individuals with autism perform. best at jobs which are structured and involve a de- gree of repetition. Some people who have autism are working as artists, piano tuners, painters, farm workers, office workers, computer operators, dishwashers, assembly line workers, or employees of sheltered workshops or other sheltered work settings.

The Adjustment in Understanding of Man"s Relation to the Physical Universe

Nowadays the scattering of galaxies and the astounding abundance of stars are forcing those who ponder such matters to a further adjustment of their concept of the place and function of man in the material universe.

In the history of the51human mind， with its increasing knowledge of the surrounding context， there must have been a time when the philosophers of the52tribes began to realize that the world was not simply centered on man himself. The geocentric concept， which accepted a universe centered on the earth， then became common53

The second adjustment in the understanding of man"s relation to the physical universe was not generally acceptable54the sixteenth century. Copernican revolution soundly55the heliocentric Concept， the theory of a universe56on the sun. Man is a stubborn adherent to official dogma; eventually， however， he accepted the sun as the center.

Then， forty years ago， came the need for a third adjustment. This57has deeply exploded man"s pride and58， for it has carried with it the knowledge of the appalling number of galaxies.

The galactocentric universe59puts the earth and its life near the edge of one great galaxy in a universe of millions of galaxies. Man becomes peripheral among the billions of stars of his own Milky Way; and， according to the revelations of paleontology and geochemistry， he is60and apparently transient in the61of cosmic time.

The downgrading of the earth and sun and the elevation of the galaxies is not the end of this62of scientific pilgrims through philosophic fields. The need for another63adjustment now64not wholly unexpected by scientists，65wholly the result of one or two scientific revelations.

Our new problem concerns the spread of life throughout the universe. As unsolicited spokesmen for all the earthly organisms of land， sea， and air， we ask the thrilling question: Are we alone？
