The Success of McDonald's

　　In 1895, a man named Raymond Kroc entered a partnership(合营公司)with two brothers named McDonald．They opened a popular restaurant in California which sold food that was easy to prepare and serve quickly．Hamburgers, French fries, and cold drinks were the main food there．Kroc opened similar eating places under the same name“Mc Donald”, and they were an instant(立即的)success．He later took over the company, and today it is one of the most famous and successful“fastfood”in America and the world．

　　Why was his idea so successful?Probably the most important reason was that his timing was right．In the 1950s, most married women stayed home to keep house and take care of their children．In the 1960s, many women returned to the workplace, this meant that they had less time and energy(精力)to do housework and preparations for meals so they relied more on“TV dinners”and fast-food restaurants．Single parents also have little time to spend in the kitchen．People living alone also depend on this type of food, since cooking for one is often more trouble than it is worth．

　　Fast-food is not part of the diet(饮食)of all Americans．Another trend(倾向)of the 1960s, sometimes called the back-to-nature movement influenced(影响)many people to avoid(避开)food that was packaged or processed(袋装的或加工好的)．This preference(偏爱)for natural foods continues to this day．

Economics (经济学) is the study of how societies with limited resources decide what to produce, how to produce and for whom to produce. What, how, and for whom to produce are problems all over the world because human needs are practically unlimited, but all societies have only limited quantities of resources that can be used to produce goods or services.

A knowledge of basic economics is important for understanding both the problems and opportunities that will face the world economy in the 21st century. As a student of economics, one will have the chance to discover how commerce(商业), government policies, and day-to-day decisions made by consumers affect his living standards. The study of economics can help him understand the influence of such events as the move to free markets in Poland and Russia, or of ups and downs in interest rate and the foreign exchange rate. Economics is influenced by developments in the many different areas of business, politics, science, nature, religion and history. And whether or not one is aware of it, economics is an important part of his life.

From a practical point of view, one's study of economics will help improve his decision-making skills. He learns a logical way to compare different courses of action. As he studies the concept (概念) of opportunity cost, for instance, he will discover that every choice he makes has both a benefit and a cost. Suppose someone decides to get a part-time job so he can earn enough money to buy a car. He will have the benefit of owning the car, but he will pay a cost in terms of the leisure hours he gives up for working so as to pay for the car and keep it in good condition. After weighing his choice in cost-benefit terms, he may decide he does not need a car any more.

68. According to the passage, economics is studied to______.

A. get more resources for human beings

B. put human needs under some control

C. satisfy the unlimited human needs with the limited resources

D. produce better goods and services for all human beings

69. Economics can help one make better decisions because he learns______.

A. how to weigh the cost and the benefit B. all the practical economic theories

C. something useful about business D. a logical way of thinking

70. Why does the person have to give up leisure hours in the example of buying a car?

A. Because he has to spend some time in the car.

B. Because he has to work extra hours to get the money.

C. Because he is busy working for his boss.

D. Because keeping a car in good condition takes much time.

71. What is the central topic of the second paragraph?

A. Influences of economics. B. Importance of knowing economics.

C. Uses of economics. D. Scope (范围) of economic studies.
