A composer writes a work, but no one can hear it until it is performed. Professional singers and players hav
2、e great responsibilities, for the composer is utterly dependent on them. A student of music needs as long and as arduous a training to become a performer as a medical student needs to become a doctor. Most training is concerned with technique, for musicians have to have the muscular proficiency of a
3、n athlete or a ballet dancer. Singers practice breathing every day, as their vocal chords would be inadequate without controlled muscular support. String players practice moving the fingers of the left hand up and down, while drawing the bow to and fro with the right arm-two entirely different movem
4、ents.Singers and instruments have to be able to get every note perfectly in tune. Pianists are spared this particular anxiety, for the notes are already there, waiting for them, and it is the piano tuners responsibility to tune the instrument for them. But they have their own difficulties; the hamme
5、rs that hit the string have to be coaxed not to sound like percussion, and each overlapping tone has to sound clear.This problem of getting clear texture is one that confronts student conductors: they have to learn to know every note of the music and how it should sound, and they have to aim at cont
6、rolling these sounds with fanatical but selfless authority.Technique is of no use unless it is combined with musical knowledge and understanding. Great artists are those who are so thoroughly at home in the language of music that they can enjoy performing works written in any century.成龙成凤网 http:/ 国内

Nevertheless, it has been said that today children interrupt their education to go to school. The distinction betwe
8、en schooling and education implied by this remark is important.Education is much more open-ended and all-inclusive than schooling. Education knows no bounds. It can take place anywhere, whether in the shower or in the job, whether in a kitchen or on a tractor. It includes both the formal learning th
9、at takes place in schools and the whole universe of informal learning. The agents of education can range from a revered grandparent to the people debating politics on the radio, from a child to a distinguished scientist. Whereas schooling has a certain predictability, education quite often produces
10、surprises. A chance conversation with a stranger may lead a person to discover how little is known of other religions. People are engaged in education from infancy on. Education, then, is a very broad, inclusive term. It is a lifelong process, a process that starts long before the start of school, a
11、nd one that should be an integral part of ones entire life.Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next. Throughout a country, children arrive at school at approximately the same time, take assigned seats, are taugh
12、t by an adult, use similar textbooks, do homework, take exams, and so on. The slices of reality that are to be learned, whether they are the alphabet or an understanding of the working of government, have usually been limited by the boundaries of the subject being taught. For example, high school st
13、udents know that there not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. There are definite conditions surrounding the formalized process of schooling.成龙成凤网 http:/ 国内首家专门教授快速、轻松、高效 记忆英语单词的专业网站QQ：28551

They are also the means by which products and services that are in limited supply are rationed among buyers. The price system of the United States is a complex network composed of the pri
15、ces of all the products bought and sold in the economy as well as those of a myriad of services, including labor, professional, transportation, and public-utility services. The interrelationships of all these prices make up the “system” of prices. The price of any particular product or service is li
16、nked to a broad, complicated system of prices in which everything seems to depend more or less upon everything else.If one were to ask a group of randomly selected individuals to define “price”, many would reply that price is an amount of money paid by the buyer to the seller of a product or service
17、 or, in other words that price is the money values of a product or service as agreed upon in a market transaction. This definition is, of course, valid as far as it goes. For a complete understanding of a price in any particular transaction, much more than the amount of money involved must be known.
18、 Both the buyer and the seller should be familiar with not only the money amount, but with the amount and quality of the product or service to be exchanged, the time and place at which the exchange will take place and payment will be made, the form of money to be used, the credit terms and discounts

Scientists are discovering more and more that the living world may hold many interesting secrets of electricity that could benefit humanity.All living cell send out tiny pulses of electricity. As the heart beats, it sends out
23、pulses of record; they form an electrocardiogram, which a doctor can study to determine how well the heart is working. The brain, too, sends out brain waves of electricity, which can be recorded in an electroencephalogram. The electric currents generated by most living cells are extremely small - of
24、ten so small that sensitive instruments are needed to record them. But in some animals, certain muscle cells have become so specialized as electrical generators that they do not work as muscle cells at all.

The on most w
27、idely accepted today is based on the assumption that drama evolved from ritual. The argument for this view goes as follows. In the beginning, human beings viewed the natural forces of the world-even the seasonal changes-as unpredictable, and they sought through various means to control these unknown
28、 and feared powers. Those measures which appeared to bring the desired results were then retained and repeated until they hardened into fixed rituals. Eventually stories arose which explained or veiled the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later cal
29、led myths, persisted and provided material for art and drama.Those who believe that drama evolved out of ritual also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used, furthermore, a suitable site had to be provided for performance
30、s and when the entire community did not participate, a clear division was usually made between the “acting area“ and the “auditorium.“ In addition, there were performers, and, since considerable importance was attached to avoiding mistakes in the enactment of rites, religious leaders 成龙成凤网 http:/ 国内

Wearing masks and costumes, they often impersonated other people, animals, or supernatural beings, and mimed the desired effect-success in hunt or battle, the coming rain, the revival of the Sun-as an a
32、ctor might. Eventually such dramatic representations were separated from religious activities.Another theory traces the theaters origin from the human interest in storytelling. According to this vies tales (about the hunt, war, or other feats) are gradually elaborated, at first through the use of im
33、personation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely related theory traces theater to those dances that are primarily rhythmical and gymnastic or that are imitations of animal movements and sounds.TelevisionsTelevision-
34、the most pervasive and persuasive of modern technologies, marked by rapid change and growth-is moving into a new era, an era of extraordinary sophistication and versatility, which promises to reshape our lives and our world. It is an electronic revolution of sorts, made possible by the marriage of t
35、elevision and computer technologies.The word “television“, derived from its Greek (tele: distant) and Latin (visio: sight) roots, can literally be interpreted as sight from a distance. Very simply put, it works in this way: through a sophisticated system of electronics, television provides the capab
36、ility of converting an image (focused on a special photoconductive plate within a camera) into electronic impulses, which can be sent through a wire or cable. These impulses, when fed into a receiver (television set), can then be electronically reconstituted into that same image.成龙成凤网 http:/ 国内首家专门教

It is a means of expression, as well as a vehicle for communication, and as such becomes a powerful tool for reaching other human beings.The field of television can be divided i
38、nto two categories determined by its means of transmission. First, there is broadcast television, which reaches the masses through broad-based airwave transmission of television signals. Second, there is nonbroadcast television, which provides for the needs of individuals or specific interest groups
39、 through controlled transmission techniques.Traditionally, television has been a medium of the masses. We are most familiar with broadcast television because it has been with us for about thirty-seven years in a form similar to what exists today. During those years, it has been controlled, for the m
40、ost part, by the broadcast networks, ABC, NBC, and CBS, who have been the major purveyors of news, information, and entertainment. These giants of broadcasting have actually shaped not only television but our perception of it as well. We have come to look upon the picture tube as a source of enterta
41、inment, placing our role in this dynamic medium as the passive viewer.Andrew CarnegieAndrew Carnegie, known as the King of Steel, built the steel industry in the United States, and, in the process, became one of the wealthiest men in America. His success resulted in part from his ability to sell the
42、 product and in part from his policy of expanding during periods of economic decline, when most of his competitors were reducing their investments.Carnegie believed that individuals should progress through hard work, but he also felt strongly that the wealthy should use their fortunes for the benefi

He opposed charity, preferring instead to provide 成龙成凤网 http:/ 国内首家专门教授快速、轻松、高效 记忆英语单词的专业网站QQ：285517323 707526607单词记不住？记不快？记不牢？赶紧就去成龙成凤网 http:/ opportunities that would allow others to help themselves. “He who dies rich, dies disgraced,“ he often said.Among his more noteworthy contribu
44、tions to society are those that bear his name, including the Carnegie Institute of Pittsburgh, which has a library, a museum of fine arts, and a museum of national history. He also founded a school of technology that is now part of Carnegie-Mellon University. Other philanthropic gifts are the Carneg
45、ie Endowment for International Peace to promote understanding between nations, theCarnegie Institute of Washington to fund scientific research, and Carnegie Hall to provide a center for the arts.Few Americans have been left untouched by Andrew Carnegies generosity. His contributions of more than fiv
