Prices determine how resources are to be used. 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 prices 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 linked 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 or, in other words, that price is the money value 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. 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 that apply to the transaction, guarantees on the product or service, delivery terms, return privileges, and other factors. In other words, both buyer and seller should be fully aware of all the factors that comprise the total "package" being exchanged for the asked-for amount of money in order that they may evaluate a given price.
价格决定资源的使用方式。价格也是有限的产品与服务在买方中的配给手段。美国的价格系统是复杂的网状系统，包括经济生活中一切产品买卖的价格，也包括名目繁多的各种服务，诸如劳动力、专职人员、交通运输、公共事业等服务的价格。所有这些价格的内在联系构成了价格系统。任何一种个别产品或服务的价格都与这个庞大而复杂的系统密切相关，而且或多或少地受到系统中其它成份的制约。
如果随机挑选一群人，问问他们如何定义"价格"，许多人会回答价格就是根据卖方提供的产品或服务，买方向其付出的钱数。换句话说，价格就是市场交易中大家认同的产品或服务的货币量。该定义就其本身来说自有其道理。但要获得对价格在任何一桩交易中的完整认识，就必须考虑到大量"非货币"因素的影响。买卖双方不但要清楚交易中的钱数，而且要非常熟悉交易物的质量和数量，交易的时间、地点，采用哪种形式付款，有怎样的'缓付和优惠，对交易物的质量保证、交货条款、退赔权利等等。也就是说，为了能估算索价，买卖双方必须通晓构成交易物价格的通盘细节。

Andrew 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 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 benefit of society. He opposed charity, preferring instead to provide educational opportunities that would allow others to help themselves. "He who dies rich, dies disgraced, " he often said.Among his more noteworthy contributions 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 Carnegie Endowment for International Peace to promote understanding between nations, the Carnegie 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 Carnegie's generosity. His contributions of more than five million dollars established 2,500 libraries in small communities throughout the country and formed the nucleus of the public library system that we all enjoy today.
被称作钢铁大王的安德鲁·卡内基在美国建立了钢铁工业。在这个过程中，他变成了美国最富有的人之一。 他的成功，部分来自于他销售产品的能力，部分来自于经济萧条时期的扩充策略。在萧条时期，他的多数对手都在缩减投资。
卡内基认为个人应该通过努力工作来获得进展，但他也强烈地感到有钱人应该运用他们的财富来为社会谋 取福利。他反对施舍救济，更愿意提供教育机会，使别人自立。卡内基经常说："富有着死去的人死得可耻。"他对社会的较重要的贡献都以他的名字命名。这些贡献包括匹兹堡卡内基学校。这个学校有一个图书馆，一个美术馆和一个国家历史博物馆;他还创立了一所技术学校，这所学校现在是卡内基梅隆大学的一部分;其他的慈善捐赠有为促进国家间了解的"卡内基国际和平基金"，为科学研究提供经费的华盛顿卡内基学院以及给各种艺术活动提供活动中心的卡内基音乐厅。
安德鲁·卡内基的慷慨大度几乎影响到每个美国人的生活。由于他超过五百万美元的捐款，2500 个图书馆得以建立起来，遍布在美国各地的小村镇，形成了我们今天还在享用的公共图书馆系统的核心。

Jogging has become the most popular individual sport in America. Many theories, even some mystical ones, have been advanced to explain the popularity of jogging. The plain truth is that jogging is a cheap, quick and efficient way to maintain physical fitness.
The most useful sort of exercise is exercise that develops the heart, lungs, and circulatory systems. If these systems are fit, the body is ready for almost any sport and for almost any sudden demand made by work or emergencies. One can train more specifically, as by developing strength for weight lifting or the ability to run straight ahead for short distances with great power s in football, but running trains your heart and lungs to deliver oxygen more efficiently to all parts of your body. It is worth noting that this sort of exercise is the only kind that can reduce heart disease, the number one cause of death in America.
Only one sort of equipment is needed a good pair of shoes. Physicians advise beginning joggers not to run in a tennis or gym shoe. Many design advances have been made in only the last several years that make an excellent running shoe in dispensable if a runner wishes to develop as quickly as possible, with as little chance of injury as possible. A good running shoe will have a soft pad for absorbing shock, as well as a slightly built-up heel and a full heelcup that will give the knee and ankle more stability. A wise investment in good shoes will prevent bilisters and the foot, ankle and knee injures and will also enable the wearer to run on paved or soft surfaces.

Upon reaching an appropriate age (usually between 18 and 21 years), children are encouraged, but not forced, to “leave the nest” and begin an independent life. After children leave home they often find social relationship and financial support outside the family. Parents do not arrange marriages for their children, nor do children usually ask permission of their parents to get married, Romantic love is most often the basis for marriage in the United States; young adults meet their future spouses through other friends, at jobs, and in organizations and religious institutions, Although children choose their own spouses, they still hope their parents will approve of their choices.
In many families, parents feel that children should make major life decisions by themselves. A parent may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do precisely the opposite of what their parents wish in order to assert their independence. A son may deliberately decide not to go into his father’s business because of a fear that he will lose his autonomy in his father’s workplace. This independence from parents is not an indication that parents and children do not love each other. Strong love between parents and children is universal and this is no exception in the American family Coexisting with such love in the American family are cultural values of self – reliance and independence.
子女一旦到适当年龄(通常是18至21岁)，要鼓励而不是强迫他们“离开窝的，财政的巢”，开始独立生活。小孩离开家后，往往在外能够与人交往，并自谋出路。父母不为子女安排婚姻，子女结婚也通常无需获得父母同意。在美国，浪漫的爱情往往是婚姻的基础，通过朋友在学校、单位、组织以及宗教团体认识自己的，爱情的未来的伴侣。尽管子女自己择偶，他们仍然希望父母能认同他们的选择。
许多家庭的父母认为，应由子女自己来做他们生活中的重大决定。家长可能会设法影响子女去从事某一职业，但子女也有选择其它职业的自由。有时为了证实自己的独立性，子女从事的工作正好与父母希望的相反。儿子可能执意不去父亲的企业工作，因为担心在那里就不能独立自主。这种不依靠父母的独立性并不意味着父母与子女之间缺乏爱心。父母和子女之间普遍都有挚爱，美国家庭也毫不例外。只不过在美国家庭之中，还融合了自主、独立的文化价值观念。

A painter hangs his or her finished pictures on a wall, and everyone can see it. A composer writes a work, but no one can hear it until it is performed. Professional singers and players have 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 an 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 movements.
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 tuner’s responsibility to tune the instrument for them. But they have their own difficulties; the hammers 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 controlling these sound 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.

Every weekday morning I take the 8:30 bus to go to my job. I know by sight several people who also fide that bus. Some of the girls work as maids. They get off at each stop in ones, twos or threes.
But at one corner something wonderful happens. Before the bus stops, a little dog races out of the nearest house. He doesn't look at two of the maids who get off. But for the third he has a joyful "Hello!". From head to tail his little body wags his happiness. Everyone on the bus watches until the maid and the dog go into the house.
One day not long ago the maid wasn't on the bus. I wondered if the dog would be waiting for her. Sure enough, he was!
He stood at the back door of the bus for a minute. I could see his joyful welcome turning into fearful worry. Where was she?
The driver closed the back door. The dog raced to the front door. It, too, shut in his face.
Everyone on the bus felt sad. Poor little pup! He looked so unhappy, standing there!
The driver couldn't stand it. He opened the door and looked down at the dog. "She didn't come today," he said, in a loud, kind voice.
A man in a front seat leaned forward. "Maybe she will come tomorrow," he called.
The dog wagged his tail as if to say "thank you." He watched the bus as we pulled away. Then he turned to trot home ── alone.
The next day everyone on the bus was happy to see the maid back again. Yes, the dog was waiting for her.
The welcome he gave her was even warmer and more delighted than usual. We all smiled at one another. How bright and good the morning suddenly seemed to us!

There was a time in my life when beauty meant something special to me. I guess that would have been when I was about six or seven years old, just several weeks or maybe a month before the orphanage turned me into an old man.
I would get up every morning at the orphanage, make my bed just like the little soldier that I had become and then I would get into one of the two straight lines and march to breakfast with the other twenty or thirty boys who also lived in my dormitory.
After breakfast one Saturday morning I returned to the dormitory and saw the house parent chasing the beautiful monarch butterflies who lived by the hundreds in the azalea bushes strewn around the orphanage.
I carefully watched as he caught these beautiful creatures, one after the other, and then took them from the net and then stuck straight pins through their head and wings, pinning them onto a heavy cardboard sheet.
How cruel it was to kill something of such beauty. I had walked many times out into the bushes, all by myself, just so the butterflies could land on my head, face and hands so I could look at them up close.
When the telephone rang the house parent laid the large cardboard paper down on the back cement step and went inside to answer the phone. I walked up to the cardboard and looked at the one butterfly who he had just pinned to the large paper. It was still moving about so I reached down and touched it on the wing causing one of the pins to fall out. It started flying around and around trying to get away but it was still pinned by the one wing with the other straight pin. Finally it's wing broke off and the butterfly fell to the ground and just quivered.
I picked up the torn wing and the butterfly and I spat on it's wing and tried to get it to stick back on so it could fly away and be free before the house parent came back. But it would not stay on him.
The next thing I knew the house parent came walking back out of the back door by the garbage room and started yelling at me. I told him that I did not do anything but he did not believe me. He picked up the cardboard paper and started hitting me on the top of the head. There were all kinds of butterfly pieces going everywhere. He threw the cardboard down on the ground and told me to pick it up and put it in the garbage can inside the back room of the dormitory and then he left.
I sat there in the dirt, by that big old tree, for the longest time trying to fit all the butterfly pieces back together so I could bury them whole, but it was too hard to do. So I prayed for them and then I put them in an old torn up shoe box and I buried them in the bottom of the fort that I had built in the ground, out by the large bamboos, near the blackberry bushes.
Every year when the butterflies would return to the orphanage and try to land on me I would try and shoo them away because they did not know that the orphanage was a bad place to live and a very bad place to die.

For many people in the U.S., sports are not just for fun. Theyre almost a religion. Thousands of sports fans buy expensive tickets to watch their favorite teams and athletes play in person.
Other fans watch the games at home, glued to their TV sets. Americas devotion to athletics has created a new class of wealthy people: professional athletes. Sports stars often receive million-dollar salaries. Some even make big money appearing in advertisements for soft drinks, shoes and even toiletries.
对许多的美国人而言，运动不只是为了好玩。它几乎成了一种宗教崇拜，数以千计的运动迷会为了能亲眼目睹他们喜爱的球队或运动员比赛而出高价购买门票。
其它的球迷则守在家里寸步不离地收看电视转播。美国人对于运动的投入形成了一个新的富有阶级：职业运动员。运动明星通常会收到上百万元的薪水。其中有些人甚至是因为替饮料、鞋，甚至个人化妆用品拍广告而赚了一大笔钱。

Not all Americans worship sports, but athletics are an important part of their culture. Throughout their school life, Americans learn to play many sports. All students take physical education classes in school.
Many people also enjoy non-competitive activities like hiking, biking, horseback riding, camping or hunting. To communicate with American sports nuts, it helps if you can talk sports.

许多人也喜欢从事一些非竞争性的活动像健行、骑单车、骑马、露营或打猎。要和美国运动迷沟通，最好是能畅谈运动。

Through the changes in the ways of making a living in a family over several generations, the cartoon aims at sounding a warning against mans wasteful use of natural resources and emphasizing the urgent need to preserve these resources.
Ever since man appeared on the earth, mans survival has been heavily relied on nature. Almost everything we use in our everyday life comes from nature, ranging from the food we eat, the water we drink, to the wood which is turned into furiture. With the development of technology and population growth, the amount and range of materials used has increased at an alarming rate. However, natural resources are not inexhaustible. Some reserves are already on the brink of exhaustion and there is no hope of replacing them. The widespread water shortage is an example in point. If man continued to squander natural resources with no thought for the future, the later generations would end up selling sand, as is the case in the cartoon, and the whole world would be in a mess.
Time is running out. It is up to us to take effective measures before the situation gets out of hand.
