If you want to stay young, sit down and have agood think. This is the research finding of a team of Japanese doctors who say that most of our brains are not getting enough exercise and as a result, we are aging unnecessarily soon.

    Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the

process of aging could be slowed down.With a team of colleagues at Tokyo National University,

he set about measuring brain volumes of a thousand people of different ages and jobs.

Computer technology enabled the researchers to get right measurements of the volume of the front and side sections of the brain, which relate to intellect and emotion, and determine the human character. Contraction (收缩) of the front and side parts as cells died was observed in some subjects in their thirties, but it was still not clear in some sixty and seventy-year-olds.Matsuzawa concluded from his tests that there is a simple remedy (补救) to the contraction normally associated with age using the head.

    The findings show in general terms that contraction of the brain begins sooner in people in the country than in towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking (萎缩) brains as farm workers, bus drivers and shop assistants.

    Matsuzawa'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 keep good blood circulation is through using the brain," he says, "Think hard and engage in conversation. Don't rely on pocket calculators."w

The team of doctors wanted to find out ______.

A. why certain people age sooner than others   B. how to make people live much longer

C. the size of certain people's brains          D. the people with more intelligence

On what are their research findings based?

A. A survey of farmers in northern Japan.

B. Tests performed on a thousand old people.

C. The study of brain volumes of different people.

D. The latest development of computer technology.

Matsuzawa thinks that _______.

A. our brains grow as we grow older

B. the front section of the brain does not shrink

C. sixty-year-old people have better brains than thirty-year-olds

D. the contraction of brains is connected with brain exercise

According to the passage, which people seem to age slower than others?

A. Farmers.     B. Lawyers.     C. Government workers.     D. Shop assistants.w

What kind of pets do people have in your country? Dogs? Cats? How about a duck, hippo(河马) or lion? Here are two cases of animal owners with unusual pets.
Barrie Hayman has a pet duck called Star. Barrie adopted(领养) him after his brothers and sisters stayed away from him at birth. Barrie, a duck breeder, realized the little duck needed special attention. So he began taking Star with him everywhere he went. “I would put him in my pocket while I did my shopping,” said Barrie. Now, at five months, Star is too big for Barrie’s pocket, but the two are still inseparable. They watch sports, together and even share a drink together. Barrie said, “He is a fantastic duck. I’ve never known any like him.” Star even has his own Facebook page, with more than 2,000 Face book friends.
Then there is the case of Tonie and Shirley Joubert in South Africa. They live with their hippo, Jessica. Tonie saved Jessica from floodwaters when she was only a day old. Jessica lives outside their riverside house, but she knows how to open the kitchen door, and often goes there for a snack. Tonie recently said, “I don’t know whether Jessica sees me as a hippo or whether she sees herself as a human.” Shirley is more certain, “Jessica sees herself as our child and I see Jessica as my daughter. I can’t imagine my life without Jessica.” Jessica is free to leave, and often visits wild hippos that live nearby. But she always returns home at night. Jessica’s website notes that she has three hippo boyfriends, but one in particular,Fred, is her favorite. They often go grazing(吃青草) together and Fred has recently moved onto the Joubert’s house as well.
【小题1】What’s the main idea of the passage?

B
Ed Viesturs grew up in Rockford, Illinois, where the tallest thing on the horizon was the water tower. But on Thursday, Viesturs became the only American to climb to the top of the world’s 14 highest mountains.
His last hike was up Mount Annapurna, in Asia’s snow-capped Himalayas. At 26, 545 feet, its peak is the 10th highest in the world. It is the mountain that inspired him to start climbing.
“It tends to be the trickiest, the most dangerous, ” said Viesturs, “There’s no simple way to climb it. There are threatening avalanches (雪崩) and ice falls that protect the mountain.”
In high school, Viesturs read French climber Maurice Herzog’s tale of climbing the icy Annapurna. Herzog’s story was of a lot of difficulty and near-death experiences. Viesturs was hooked right away.
Viesturs got his start on Washington’s Mount Rainier in 1977, guiding hikes in the summer. Fifteen years ago, he set out to walk up to the world’s highest peaks. Finally, he’s done.
The pioneering climber talks about mountains as if they were living creatures that should be treated with respect. “You have to use all of your senses, all of your abilities to see if the mountain will let you climb it,” said Viesturs. “If we have the patience and the respect, and if we’re here at the right time, under the right circumstances (情况), they allow us to go up, and allow us to come down. ”
What’s next for a man who can’t stop climbing? “I’m going to hug my wife and kids and kind of kick back and enjoy the summer. ” says Viesturs. But for a man who’s climbed the world’s 14 tallest mountains, he will probably soon set off on yet another adventure.
59. What record has Ed Viesturs set?
A. He has succeeded in climbing to the top of the world’s 14th highest mountain.
B. He has become the first American to climb to the top of the world’s 14 highest mountains.
C. He has become the first to climb to the height of 26, 545 feet.
D. He has become the first man to climb to the top of 14 highest mountains in the world.
60. The underlined word “hooked” in Paragraph 4 can be replaced by “__________”.
A. frightened               B. discouraged                 C. interested              D. upset
61. The author used Viestures’ words in Paragraph 6 to support a view that __________.
A. mountain climbing is a dangerous sport
B. mountains should be regarded as living creatures
C. mountain climbing needs more strength than skills
D. those who like mountain climbing won’t stop climbing
62. What’s the next probable plan of Viestures?
A. Stopping climbing and staying with his family.
B. Climbing to the top of the world’s 14 tallest mountains again.
C. Meeting other challenges.
D. Writing down the experiences about his adventure.                   

Thomas Alva Edison was an American inventor, scientist and businessman who invented many things that greatly influenced life around the world, such as the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Edison has been recognized as the creator of the first industrial research laboratory. It is he who came up with the concept of providing electricity for home. His first power station was on Manhattan Island, New York.

Edison was born in Milan, Ohio, and grew up in Port Huron, Michigan. He was the seventh and last child of his family. When he was young, Edison stayed at home and was taught by his mother. Edison recalled later, “My mother was the making of me. She was so true, so sure of me; and I felt I had someone to live for, someone I must not disappoint.” During his childhood, he suffered from scarlet fever which affected his hearing.

Young Edison sold candy and newspapers on trains running from Port Huron to Detroit, and he sold vegetables to supplement his income. These jobs, though insignificant, inspired him greatly. He realized that he had a talent for business. These talents eventually made him founder of 14 companies, including General Electric, which is still in existence and is the largest publicly traded company in the world.

Edison started as a telegraph operator and this was the field in which he came up with the first invention. The invention which first gained him fame was the phonograph in 1877. The invention seemed magical, as nothing similar had ever been thought of before. Funded by the successful sale of the telegraph at a price of $10,000, Edison built his own research laboratory in Menlo Park, New Jersey.

The laboratory expanded rapidly over the decade. In 1892, it was confirmed that Edison was the official inventor of the carbon microphones, which was used in all telephones. Although he attempted to make use of X-rays to take radiographs, he quit the project and admitted his fear of X-rays in public.

Thomas Edison died of diabetes at his home in New Jersey, on October 18, 1931 and in honor of his contributions, Life magazine (USA), in a special double issue in 1997, placed Edison first in the list of the “100 Most Important People in the Last 1000 Years”, noting that the light bulb he promoted “lit up the world”.
