America is a country on the move. In unheardof numbers, people of all ages are exercising their way to better health. According to the latest figures, 4 percent of American adults exercise regularly-up 12 percent from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they would be more attractive and confident if they were more active. It is hard not to get the message. The virtues of physical fitness are shown on magazine covers, postage stamps, and television ads of everything from beauty soaps to travel books. Exercise as a part of daily life did not catch on until the late 195s when research by military doctors began to show the health benefits of doing regular physical exercises. Growing publicity (宣传) for races held in American cities helped fuel a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally rewarding-and sometimes safer-forms of exercise, such as walking and swimming, running remains the most popular form of exercise. As the popularity of exercise continues to mount, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle groups vigorously (强有力地) enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time. Doing such physical exercises three times or more a week will produce considerable improvements in physical health in about three months. 5.It can be learnt from the passage that the health benefits of exercise .

Yet, when one becomes rich, he wants people to know it.And even if he does not become very rich, he wants people to think that he is.That is what “keeping up with the Joneses” is about.It is the story of someone who tries to look as rich and as successful as his neighbors.
The expression was first used in 1913 by a young American by the name of Arthur Momand.He told this story about himself: he began earning $125 a week at the age of 23.That was a lot of money in those days.Young Momand was very proud of his riches.He got married and moved with his wife to a very wealthy neighborhood outside New York City.But just moving there was not enough.When he saw that rich people rode horses, Momand went horse riding every day.When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.
It was like a race, but one could never finish this race because one was always trying to keep up.Momand and his wife could not do that.
The race ended for them when they could no longer pay for their new way of life.They left their wealthy neighborhood and moved back to an apartment in New York City.
Momand looked around him and noticed that many people do things just to keep up with their neighbors.He saw the funny side of it and started to write a series of short stories.He called it “keeping up with the Joneses”, because “Jones” is a very common name in the United States.“Keeping up with the Joneses” came to mean keeping up with the people around you.Momand’s series appeared in different newspapers across the country for over 28 years.
Every city has an area where people want to live because others will think better of them if they do.And there are “Joneses” in every city of the world.But one must get tired of trying to keep up with the Joneses, because no matter what one does, Mr.Jones always seems to be ahead.
