對於公共英語二級的準備有人漫不經心，但是也有人認認真真。下面是小編為大家整理的公共英語二級閱讀理解擴充套件文章，希望對大家有用。
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.
價格決定資源的使用方式。價格也是有限的產品與服務在買方中的配給手段。美國的價格系統是複雜的網狀系統，包括經濟生活中一切產品買賣的價格，也包括名目繁多的各種服務，諸如勞動力、專職人員、交通運輸、公共事業等服務的價格。所有這些價格的內在聯絡構成了價格系統。任何一種個別產品或服務的價格都與這個龐大而複雜的系統密切相關，而且或多或少地受到系統中其它成份的制約。如果隨機挑選一群人，問問他們如何定義"價格"，許多人會回答價格就是根據賣方提供的產品或服務，買方向其付出的錢數。換句話說，價格就是市場交易中大家認同的產品或服務的'貨幣量。該定義就其本身來說自有其道理。但要獲得對價格在任何一樁交易中的完整認識，就必須考慮到大量"非貨幣"因素的影響。買賣雙方不但要清楚交易中的錢數，而且要非常熟悉交易物的質量和數量，交易的時間、地點，採用哪種形式付款，有怎樣的緩付和優惠，對交易物的質量保證、交貨條款、退賠權利等等。也就是說，為了能估算索價，買賣雙方必須通曉構成交易物價格的通盤細節。
公共英語二級閱讀理解擴充套件文章二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 g 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.
被稱作鋼鐵大王的安德魯·卡內基在美國建立了鋼鐵工業。在這個過程中，他變成了美國最富有的人之一。 他的成功，部分來自於他銷售產品的能力，部分來自於經濟蕭條時期的擴充策略。在蕭條時期，他的多數對手都在縮減投資。
卡內基認為個人應該通過努力工作來獲得進展，但他也強烈地感到有錢人應該運用他們的財富來為社會謀 取福利。他反對施捨救濟，更願意提供教育機會，使別人自立。卡內基經常說："富有著死去的人死得可恥。"他對社會的較重要的貢獻都以他的名字命名。這些貢獻包括匹茲堡卡內基學校。這個學校有一個圖書館，一個美術館和一個國家歷史博物館;他還創立了一所技術學校，這所學校現在是卡內基梅隆大學的一部分;其他的慈善捐贈有為促進國家間瞭解的"卡內基國際和平基金"，為科學研究提供經費的華盛頓卡內基學院以及給各種藝術活動提供活動中心的卡內基音樂廳。
安德魯·卡內基的慷慨大度幾乎影響到每個美國人的生活。由於他超過五百萬美元的捐款，2500 個圖書館得以建立起來，遍佈在美國各地的小村鎮，形成了我們今天還在享用的公共圖書館系統的核心。
