单选题For three decades we"ve heard endlessly about the virtues of aerobic (increasing oxygen consumption) exercise. Medical authorities have praised running and jumping as the key to good health, and millions of Americans have taken to the treadmill (踏车) to reap the rewards. But the story is changing. Everyone from the American Heart Association to the surgeon general"s office has recently embraced strength training as a complement to aerobics. And as weight lifting has gone mainstream, so has the once obscure practice known as "Super Slow" training. Enthusiasts claim that by pumping iron at a snail"s pace—making each "rep" (repeat) last 14 seconds instead of the usual seven—you can safely place extraordinary demands on your muscles, and call forth an extraordinary response. Slow lifting may not be the only exercise you need, as some advocates believe, but the benefits are often dramatic. Almost anyone can handle this routine. The only requirements are complete focus and a tolerance for deep muscular burn. For each exercise—leg press, bench press, shoulder press and so on—you set the machine to provide only moderate resistance. But as you draw out each rep, depriving yourself of impetus, the weight soon feels unbearable. Defying the impulse to stop, you keep going until you can"t complete a rep. Then you sustain your vain effort for 10 more seconds while the weight sinks gradually toward its cradle. Intense? Uncomfortable? Totally. But once you embrace muscle failure as the goal of the workout, it can become almost pleasure. The goal is not to burn calories while you"re exercising but to make your body burn them all the time. Running a few miles may make you sweat, but it expends only 100 calories per mile, and it doesn"t stimulate much bone or muscle development. Strength training doesn"t burn many calories, either. But when you push a muscle to failure, you set off a pour of physiological changes. As the muscle recovers over several days, it will thicken and the new muscle tissue will demand sustenance. By the time you add three pounds of muscle, your body requires an extra 9,000 calories a month just to break even. Hold your diet steady and, very quickly, you are vaporizing body fat. One might have benefited from any strength-training program. But advocates insist that the slow technique is safer and more effective than traditional methods.

单选题From the third paragraph, we can conclude that______.

单选题Of late, there have been several posts suggesting that America has no culture or that what culture it has is somehow inferior to that of other societies. Of course, it cannot be both. To suggest that America has, in some sense, an inferior culture is to grant that it has a culture. America most definitely has culture and the culture of America is easily the most dominant of the world. Whether it is McDonald"s in the heart of what was once the center of the Evil Empire, or Arnold Schwarzenagger storming across German theatres, or Disneyland sending the French snobs into hysteria, American culture dominates Europe as never before. And it is not just Europe. Enter any shopping center in Asia and the odds are that the music blasting over the sound system is American pop music. Madonna look-alikes speak Mandarin Chinese. Often, American culture is derided by the so-called "intellectuals". (And by that, I do not mean the traditional definition of those who use their intellect to make a living as, in a increasingly service economy, there are few people today who would not fit into that category but, rather, people who fancy themselves as in some way gifted to impose their views upon the rest of us, to save us from ourselves.) What is it about American culture that annoys the "intellectuals" so much? It is precisely that which differentiates it from other cultures, particularly the cultures of Europe ("intellectuals" tending to be europhiles). Whereas European culture (and, indeed, most pre-industrial cultures) sprang from their traditions of aristocracy and the subservience of society to the ruling class, American culture serves the middle-class, the vulgar, if you will. Whereas European culture is concerned with what is exclusive and aloof, American culture is concerned with what is common and accessible. You don"t need classes in school in rock music appreciation or the finer aspects of eating pizza. Some have suggested that America is doomed because it has no culture. But the contrary is more likely the case. In spite of the best efforts of the multi-cultural fascists, America has yet to fulfill its manifest destiny primarily because its culture is not only dominating and assimilating immigrants from every corner of the world, it is, indeed reaching out to every corner of the world and creating a world community, a community centered on the individual, every individual not just those gifted with expensive tastes.
