单选题Diet and exercise are keys to healthy giving. But you know all this. So our aim is to give you the shortcuts, the little-known tricks and proven methods to help prevent boredom and hopelessness in your quest for good health. That"s what the Health and Fitness Tips Site is all about. 1 Make it a daily challenge to find ways to move your body. Climb stairs if given a choice between that and escalators or elevators. Walk your dog; chase your kids; toss bails with friends; mow the lawn. Anything that moves your limbs is not only a fitness tool, it"s a stress buster. Think "move" in small increments of time. It doesn"t have to be an hour in the gym or a 45-minute aerobic dance class or tai chi or kickboxing. But that"s great when you"re up to it. Meanwhile, move more. Thought for the day: Cha, Cha, Cha...Then do it! 2 Avoid the obvious fat-contained food such as fried foods, burgers and other fatty meats (i. e. pork, bacon, ham, ribs and sausage). Dairy products such as cheese, cottage cheese, milk and cream should be eaten in low fat versions. Nuts and sandwich meats, mayonnaise (蛋黄酱), margarine (人造黄油), butter and sauces should be eaten in limited amounts. Most are available in lower fat versions such as substitute butter, fat free cheeses and mayonnaise. Thought for the day: Lean, mean, fat-burning machine...Then be one! 3 The jury is definitely in on this verdict. Ever since 1960 when the Surgeon General announced that smoking was harmful to your health, Americans have been reducing their use of tobacco products that kill. Just recently, we"ve seen a surge in smoking in adolescents and teens. Could it be the Hollywood influence? It seems the stars in every movie of late smoke cigarettes. Beware. Warn your children of the false romance or "tough guy" stance of Hollywood smokers. Thought for the day: Give up just one cigarette then the next one. 4 Easier said than done, stress busters (压力消除器) come in many forms. Some techniques recommended by experts are to think positive thoughts. Spend 30 minutes a day doing something you like. Soak in a hot tub; walk on the beach or in a park; read a good book; visit a friend; play with your dog; listen to soothing music; watch a funny movie. Get a massage, a facial or a haircut. Meditate. Count to ten before losing your temper or getting angry. Avoid difficult people when possible. Thought for the day. When seeing red, think pink clouds then float on them. 5 If you can"t live in a smog-free environment, at least avoid smoke-filled rooms, high traffic areas, breathing in highway fumes and exercising near busy thoroughfares. Exercise outside when the smog-rating is low. Exercise indoors in air conditioning when air quality is good. Plant lots of shrubbery in your yard. It"s a good deterrent for pollution and dirt from the street. Thought for the day. Smoke gets in your eyes..., and your mouth, and your nose and your lungs as do pollutants. A. Eat Less B. Quit Smoking C. Cut Fat D. Move More E. Reduce Stress F. Control Your Temper G. Protect Yourself from Pollution

单选题 The rise of multinational corporations (跨国公司), global marketing, new communicationstechnologies, and shrinking cultural differences have led to an unparalleled increase in globalpublic relations or PR. Surprisingly, since modern PR was largely an American invention, the U.S. leadership inpublic relations is being threatened by PR efforts in other countries. Ten years ago, for example,the world's top five public relations agencies were American-owned. In 1991, only one was. TheBritish in particular are becoming more sophisticated and creative. A recent survey found that morethan half of all British companies include PR as part of their corporate (公司的) planningactivities, compared to about one-third of U.S companies. It may not be long before Londonreplaces New York as the capital of PR. Why is America lagging behind in the global PR race? First, Americans as a whole tend tobe fairly provincial and take more of an interest in local affairs. Knowledge of world geography, forexample, has never been strong in this country. Secondly, Americans lag behind their Europeanand Asian counterparts (相对对应的人) in knowing a second language. Less than 5 percent ofBurson-Marshall's U.S employees know two languages. Ogilvy and Mather has about the samepercentage. Conversely, some European firms have half or more of their employees fluent in asecond language. Finally, people involved in PR abroad tend to keep a closer eye on internationalaffairs. In the financial PR area, for instance, most Americans read the Wall Street Journal.Overseas, their counterparts read the Journal as well as the Financial Times of London and TheEconomist, publications not often read in this country. Perhaps the PR industry might take a lesson from Ted Turner of CNN (Cable NewsNetwork) . Turner recently announced that the word "foreign" would no longer be used on CNNnews broadcasts. According to Turner, global communications have made the nations of the worldso interdependent that there is no longer any such thing as foreign.

单选题This country, as Lincoln said, belongs to the people. So do the natural resources which make it rich. They supply the basis of our prosperity now and hereafter. In preserving them, which is a national duty, we must not forget that monopoly is based on the control of natural resources and natural advantages, and that it will help the people little to conserve our natural wealth unless the benefits which it can yield are given back to the people. Let us remember, also, that conservation does not stop with the natural resources. The principle of making the best use of all we have requires that we stop the waste of human life in industry and prevent the waste of human welfare which flows from the unfair use of concentrated power and wealth in the hands of men whose eagerness for profit blinds them to the cost of what they do. We have no higher duty than to promote the efficiency of the individual. There is no surer road to the efficiency of the nation.
