单选题 重阳节 重阳节(the Double Ninth Festival)，在每年的农历九月初九，是中国的传统节日。早在战国时期(the Warring States Period)人们就开始过重阳节，到了唐代，重阳成为全国性的民间节日。攀登高山是重阳节一项重要的习俗，据说这样可以避免灾难，并且带来好运。“九九”和“久久”在汉语中同音，因此，人们把重阳节与祝福老人长寿联系在一起。1989年，中国把重阳节定为“老人节”(Senior's Day)，使之成为一个全国性的尊老、爱老、助老的节日。在节日这天会组织各种活动，以帮助老人们交流感情、强身健体。

单选题 The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise (有氧操). Millions of individuals became engaged in a variety of aerobic activities, and literally thousands of health spas developed around the country to capitalize (获利 ) on this emerging interest in fitness, particularly aerobic dancing for females. A number of fitness spas existed prior to this aerobic fitness movement, even a national chain with spas in most major cities. However, their focus was not on aerobics, but rather on weight-training programs designed to develop muscular mass, strength, and endurance in their primarily male enthusiasts. These fitness spas did not seem to benefit financially from the aerobic fitness movement to better health, since medical opinion suggested that weight-training programs offered few, if any, health benefits. In recent years, however, weight training has again become increasingly popular for males and for females. Many current programs focus not only on developing muscular strength and endurance but on aerobic fitness as well. Historically, most physical-fitness tests have usually included measures of muscular strength and endurance, not for health-related reasons, but primarily because such fitness components have been related to performance in athletics. However, in recent years, evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health benefits as well. The American College of Sports Medicine now recommends that weight training be part of a total fitness program for healthy Americans. Increased participation in such training is one of the specific physical activity and fitness objectives of Healthy People 2000, National Health Promotion and Disease Prevention Objectives.

单选题 The American economic system is organized around a basically private-enterprise, market-oriented economy in which consumers largely determine what shall be produced by spending their money in the marketplace for those goods and services that they want most. Private businessmen, striving to make profits, produce these goods and services in competition with other businessmen; and the profit motive, operating under competitive pressures, largely determines how these goods and services are produced. Thus, in the American economic system it is the demand of individual consumers, coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes, that together determine what shall be produced and how resources are used to produce it. An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers. In the American economy, this mechanism is provided by a price system, a process in which prices rise and fall in response to relative demands of consumers and supplies offered by seller-producers. If the product is in short supply relative to the demand, the price will be bid up and some consumers will be eliminated from the market. If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to increase the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product. Thus, price is the regulating mechanism in the American economic system. The important factor in a private-enterprise economy is that individuals are allowed to own productive resources (private property), and they are permitted to hire labor, gain control over natural resources, and produce goods and services for sale at a profit. In the American economy, the concept of private property embraces not only the ownership of productive resources but also certain rights, including the right to determine the price of a product or to make a free contract with another private individual.
