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

bellow or howl with laughter. But when something strikes our "funny bone", our
diaphragm flutters up and down, and we laugh.
66. ______ Stories are among the most popular forms of humor. As a rule, a story is considered inferior if it embarrassed someone, if it makes something sacred appear common, if it makes a person’s weakness the cause for laughter, if it has to have vulgarity to be funny, or if everyone cannot join in the enjoyment of the joke. People enjoy very much the various situations of humor. If a man meets a lady on the street, tips his hat to her, and a pigeon flies out from beneath it, most of the people who see it would roar with laughter. This is called the humor of the unexpected happening. 我来回答: 提交
