Passage Two
In 2000, with little but a bar and a church left to make it a destination, tiny St. James, Nebraska, was taken off state highway maps. Then the church closed, and the small farm village in the state’s northeast corner looked set to just disappear. Thanks to five devoted women, it didn’t.
In May 2001, after meeting with staff from the Center for Rural Affairs, the friends—Louis Guy, Vicky Koch, Jeanette Pinkelman, Mary Rose Pinkelman and Violet Pinkelman—opened a weekend market for vendors(小商贩) to sell handcrafts and local food.
“We felt like, what can we do to bring the community together?” says Mary Rose Pinkelman, “We decided to make a place to sell local goods.” They set up shop in the church school, which, though closed for nearly 40 years, had been well maintained. The first weekend, 16 vendors look over an old classroom. The result was an instant hit. Today, the market draws up to 70 vendors----who sell such items as homemade jellies, baked goods, hand-woven rugs, and farm-grown produce----and what Pinkelman calls an unexpected number of visitors. In the process, the market has made St. James a destination again, putting it back on the state road map.
40. According to Para. 1, what fate was St. James Nebraska suffering?
A The replacement of the church school
B The disappearance from highway maps
C The closedown of the bar
D The set-up of a market
Psychologists deal with the mind and behavior. of people. Your mind consists of all your feelings, thoughts and ideas. It is the result of one part of the brain called the cerebrum. Your behavior. is the way you act or conduct yourself. Examples of behavior. include shouting, crying, laughing and sleeping.
Several people have been instrumental in the field of psychology. Whihelm Wundt set up the first psychological laboratory in Leipzig, Germany, in 1879. Ivan Pavlov, a Russian, is noted for his experiments with dogs in which he studies their reflexes(反射)and reactions. Around 1900, Sigmund Freud, stated his theory that people try to repress (control, hide) memories or thoughts that they believe were not good.
Psychologists should not be confused with psychiatrists who deal with mental illness. They are medical doctors who treat people.
This passage is mainly about ______.
A.studying the mind
B.memories and people
C.famous psychologists
D.the study of mental illness
Professor Faulkner wanted to find out why healthy farmers in northern Japan appeared to be losing their ability to think and to reason at a relatively early age, and how the process of ageing could be slowed down.
He set about measuring brain volumes of a thousand people of different ages and occupations.
Computer technology enabled him to obtain precise measurements of the volume of the front andside sections of the brain, which relate to intelligence and emotion, and determine the human character.
Contraction of front and side parts--as cells die off--was observed in some subjects in their thirties, but it was still not evident in some sixty-and seventy-year-olds.
Faulkner concluded from his tests that there is a simple way to slow the contraction--using the head.
The findings show that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Faulkner, are lawyers, followed by university professors and doctors. White-collar workers doing routine work are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant.
Faulkner's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to maintain good blood circulation is through using the brain," he says. "Think hard and engage in conversstion, Don't rely on pocket calculators."
Professor Faulkner wanted to find out ______.
A.how people's brains shrink
B.the way of making people live longer
C.the size of certain people's brains
D.why certain people aged sooner than others
