In the United States many have been told that anyone can become rich and successful if
he works hard and has some good luck.

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.

Losing your ability to think and remember is prett...

Losing your ability to think and remember is prettyscary. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips, you probably needn't worry. There are pretty clear differences between signs of dementia andage-related memory loss. After age 50, it's quite common to have trouble remembering the names of people, places andthings quickly, says Dr. Kirk Daffner of Brigham and Women's Hospital in Boston. The brain ages just like the rest of the body. Certain parts shrink, especially areas in the brainthat are important to learning, memory and planning. Changes in brain cells can affectcommunication between different regions of the brain. And blood flow can be reduced asblood vessels narrow. Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. Butif you forget the plot of the movie or don't remember even seeing it, that's far moreconcerning, Daffner says. When you forget entire experiences, he says, that's "a red flag that something more seriousmay be involved." Forgetting how to operate a familiar object like a microwave oven, orforgetting how to drive to the house of a friend you've visited many times before can also besigns of something going wrong. But even then, Daffner says, people shouldn't panic. There are many things that can causeconfusion and memory loss, including health problems like temporary stoppage of breathingduring sleep, high blood pressure, or depression, as well as medications (药物) likeantidepressants. You don't have to figure this out on your own. Daffner suggests going to your doctor to checkon medications, health problems and other issues that could be affecting memory. And the bestdefense against memory loss is to try to prevent it by building up your brain's cognitive (认知的) reserve, Daffner says. "Read books, go to movies, take on new hobbies or activities that force one to think in novelways," he says. In other words, keep your brain busy and working. And also get physicallyactive, because exercise is a known brain booster.Why does the author say that one needn't be concerned about memory slips? 1..Why does the author say that one needn't be concerned about memory slips?()

A、Not all of them are symptoms of dementia.

B、They occur only among certain groups of people.

C、Not all of them are related to one's age.

D、They are quite common among fifty-year-olds.

Many doctors are now trained in techniques to lessen tension and stress. Here health pro

fessionals reveal their favorite methods.

Comfort with food. When diet expert Judith Wurtman is stressed out, she does what a lot of people do this time of year: she reaches for food .But in her case, it’s a healthy rice cake or two. “My research suggests that carbohydrates (碳水化合物) raise levels of a brain chemical, which has a calming effect on the entire body,” says the MIT research scientist. “So signs of stress — such as anger, tension, and inability to focus — are eased.”

Run from your problems. Dr. Kenneth H. Cooper, who popularized aerobics (有氧运动) through his1968 book by that name, handles his own stress with a daily after-work run. He knows that physical activity reduces anxiety and depression. “Aerobic exercise is the best way to dissipate stress,”says Cooper.

Look to the light side. On his way to the hospital where his father was to have surgery Joel Goodman shared a hotel bus with anxious relatives of several patients. The driver began telling his stressed-out passengers a few jokes. “Then he did some magic tricks that had my mother and me laughing.” Goodman says. “In that five-minute ride he taught us that humor can lessen our stress.”

The surgery was successful, and Goodman was so moved by his experience that he researched laughter’s power. “A good laugh relaxes muscles, reduces blood pressure, restrains stress-related hormones and enhances the immune system (免疫系统),” he says.

Go green. Coffee, loaded with hidden sources of caffeine, stimulates (刺激) the nervous system and can make you feel stressed more easily. That’s why Arizona Doctor Andrew Weil, author of best seller Spontaneous Healing, does not take caffeine. “When I want gentle energy, I drink green tea. It contains a caffeine-like element”, Weil says. It also contains compounds that, some studies suggest, have anti-cancer effects.

16. The following are ways to free you from stress EXCEPT__________.

A. looking at things in a more relaxed way

B. getting a lot of sleep during the day

C. eating some food with carbohydrates

D. doing some aerobic exercise

17. Eating or drinking the following can be helpful in freeing you from stress EXCEPT________.

A. drink green tea B. eat some bread

C. eat some rice cake D. drink a lot of coffee

18. A good laugh is very helpful EXCEPT to__________.

A. reduce blood pressure B. restrain stress-related hormones

C. enhance the immune system D. take a holiday

19. What is the meaning of the word “dissipate” in the part “Rum from your problems”?

A. lessen. B. Depress. C. Disturb. D. Level.

20. Which of the following group of people can have a happier life, according to passage?

A. Those who are continuously eating something.

B. Those who are always engaged in working.

C. Those who use right methods to reduce tension.

D. Those who study medicine or psychology.

Sports and games make our bodies strong, prevent us from getting too fat, and keep us
healthy.But these are not their only use.They give us valuable practice in making eyes, brain and muscles work together.In tennis, our eyes see the ball coming, judge its speed and direction and pass this information on to the brain.The brain then has to decide what to do, and to send its orders to the muscles of the arms, legs, and so on, so that the ball is met and hit back where it ought to go.All this must happen with very great speed, and only those who have had a lot of practice at tennis can carry out this complicated chain of events successfully.For those who work with their brains most of the day.The practice of such skills is especially useful.

Sports and games are also very useful for character-training.In their lessons at school, boys and girls may learn about such virtues (品德) as unselfishness, courage, discipline (遵纪守法) and love of one's country; but what is learned in books cannot have the same deep effects on a child's character as what is learned by experience.The ordinary day-school cannot give much practical training in living, because most of the pupils'time is spent in classes, studying lessons.So it is what the pupils do in their spare time that really prepares them to take their place in society as citizens when they grow up.If each of them learns to work for his team and not for himself on the football field, he will later find it natural to work for the good of his country instead of only for his own benefit.

36.When we play tennis we have to ()

A.use, first, our eyes, then the brain and finally the muscles

B.make our eyes, brain and muscles work almost at the same time

C.use mainly the arms and legs to hit the ball

D.use mainly the muscles so that the ball is met and hit back

37.The “complicated chain of events”refers to ()

A.the passing of information and making of decisions

B.the meeting and hitting back of the ball

C.the coordinated (协调的) movements of eyes, brain and muscles

D.a lot of practice before playing tennis

38.By character-training, the author means that sports and games can help children ()

A.live a better life when they grow up

B.know better how to behave properly in their future life

C.understand better the virtues they learn in books

D.All of the above

39.According to the author, a child's character can be most deeply influenced by ().

A.what he does out of class

B.what he learns in books

C.his place in society

D.his lessons at school

40.What kind of virtue can playing football build in a player? ()

A.Selfishness.

B.Tearn spmt.

C.Love for himself.

D.Friendliness.
