Three-Dimensional （3D） movies have been becoming more and more popular in recent years．It seems 3D TV sets may be going into family households in the near future．While new digital 3D technology has made the experience more comfortable for many, for some with eye problems, long 3D viewing may result in an aching head, doctors say．

         "There are a lot of people walking around with very minor eye problems, which under normal situations, the brain deals with naturally," said Dr Michael Rosenberg, an ophthalmologist （眼科医师） in Chicago．He said in a 3D movie, these people face a completely new sensory experience．"That translates into greater mental effort, making it easier to get a headache," Rosenberg told Reuters．

         In normal vision, each eye sees things at a slightly different angle．"When that gets processed in the brain, that creates the perception （感觉） of depth," said Dr Deborah Friedman, an ophthalmologist in New York．The images people see in three dimensions in the movies are not calibrated （校准的） in the same way that their eyes and brain are．"If your eyes are a little off to begin with, then it's really throwing a whole degree of effort that your brain now needs

to exert （竭尽全力）," he said．                    

         Dr John Hagan, a Kansas City ophthalmologist, said some people who do not have normal depth perception cannot see in 3D at all．He said people with eye muscle problems, in which the eyes are not pointed at the same object, have trouble processing 3D images．

         Rock Heineman, a spokesman for RealD, a provider of 3D equipment to theaters, said headaches and nausea were the main reasons 3D technology never took off．

         Heineman said older 3D technology used two film projectors（放映机）, one that projected a left-eye image and one that projected a right-eye image．Three-D glasses would allow viewers to see a different image in each eye．

         "People often complained of headaches and it was really because the projectors weren’t lined up," Heineman said．

         Now his company has developed a new single digital projector, which switches between the left and the right-eye image 144 times a second, to help overcome some of the old problems．

         "By going to a single digital projector, those problems were solved," he said．Friedman said he thinks most people will do fine with 3D movies and with 3D TVs, but Rosenberg said people may quickly tire of the novelty （新鲜事物）．"I suspect there will be a lot of people who say it's sort of neat, but it's not really comfortable," he said．

When I was quite young, I discovered that somewhere inside the telephone lived an amazing

person - "Information Please" and there was nothing she did not know.　

One day while my mother was out, I hit my finger with a hammer. The pain was terrible, but

there was no one home to give me any sympathy. I walked around the house, finally arriving at the telephone! Quickly, I called “Information Please" and told her what happened.  She told me to open the icebox and hold a little piece of ice to my finger.

After that, I called "Information Please" for everything. When my pet bird died, I told

"Information Please" the sad story. She tried to comfort me, she said quietly, "Paul, always remember that there are other worlds to sing in." Somehow I felt better. Another day I was on the telephone, “How do you spell ‘grateful’? ". All this took place in a small town in the Pacific Northwest. When I was 9, we moved to Boston.

A few years later, on my way to college, my plane put down in Seattle. I had about half an

hour or so between planes. Without thinking, I dialed my hometown operator and said, "Information, please."    　　

Surprisingly, I heard the small, clear voice I knew so well, "Information." I hadn't planned on

this but I heard myself saying, "Could you please tell me how to spell ‘grateful’?"  

There was a long pause. Then came the soft-spoken answer, "I guess your finger must have

healed by now."   I laughed. "So it's really still you," I said, "I wonder if you have any idea how much you meant to me during that time."  I told her how often I had thought of her over the years and asked if I could call her again. "Please do," she said, "Just ask for Sally."　　

Three months later I was back in Seattle. A different voice answered me. I was told that Sally

passed away five weeks before.   　　

Before I could hang up she told me that Sally left a message for me—“Tell him I still say

there are other worlds to sing in. He'll know what I mean.”  I thanked her and hung up. I knew what Sally meant.

Never underestimate the impression you may make on others. Whose life have you touched

today?

One day in l965, when I worked at View Ridge School in Seattle, a fourth-grade teacher approached me. She had a student who finished his work before all the others and needed a challenge. "Could he help in the library?" She asked. I said, "Send him along."

　　Soon a slight, sandy-haired boy in jeans and a T-shift appeared. "Do you have a job for me?" he asked.

　　I told him about the Dewey Decimal System for shelving books. He picked up the idea immediately. Then I showed him a stack of cards for long-overdue books that I was beginning to think had actually been returned but were misshelved with the wrong cards in them. He said, "Is it kind of a detective job?" I answered yes, and he became working.

　　He had found three books with wrong cards by the time his teacher opened the door and announced, "Time for break!" He argued for finishing the finding job; She made the case for fresh air. She won.

　　The next morning, he arrived early. "I want to finish these books," he said. At the end of the day, when he asked to be a librarian on a regular basis, it was easy to say yes. He worked untiringly.

　　After a few weeks I found a note on my desk, inviting me to dinner at the boy's home. At the end of a pleasant evening, his mother announced that the family would be moving to neighbouring school district. Her son's first concern, she said, was leaving the View Ridge library. "Who will find the lost books?" he asked.

　　When the time came, I said a reluctant good-bye. I missed him, but not for long. A few days later he came back and joyfully announced: "The librarian over there doesn't let boys work in the library. My mother got me transferred back to View Ridge. My dad will drop me off on his way to work. And if he can’t, I'll walk!"

I should have had an inkling(感觉) such focused determination would take that young man wherever he wanted to go. What I could not have guessed, however, was that he would become a wizard of the Information Age: Bill Gates, tycoon of Microsoft and America's richest man.

Research shows that childhood friendships are important indicators of future success and social adjustment. Children's relationships with peers (同龄人) strongly influence their success in school, and children with fewer friends are more likely dropping out of school, becoming sad and other problems.

Making and Keeping Friends Is More Than Child's Play

When 6-year-old Rachel returned to school on a recent Monday morning, her eyes immediately scanned the playground for her friend Abbie. Though they were only separated by a weekend, the girls "ran right into each other's arms and hugged," recalls Rachel's mother Kathryn Willis of Gilbert. "It was like a scene from a movie."

Most parents instinctively (本能地) know that having friends is good for their child. Experts agree that friendship is not simply child's play, but a powerful predictor of social adjustment throughout life.

A Skill for Life

"Childhood friendships serve as a very important training ground for adulthood," says Dr. Robbie Adler-Tapia, psychologist with the Center for Children's Health & Life Development.

Researcher William Hartup states, "Peer relations contribute significantly to both social and cognitive (认知的) development." Hartup concludes that the single best childhood predictor of adult social adaptation is not school grades or classroom behavior, but rather, how well a child gets along with other children.

The work of Arizona State University proves that just as being able to make and keep friends is beneficial to kids, so is the lack of friends detrimental.

Good Friendships Don't Just Happen

Experts agree that it is basic for children to develop high-quality friendships. But, researchers warn, these friendships don't necessarily just happen. Often, a good friendship begins with involved （卷入，牵连）parents.

Valley psychologist Dr. Lynne Kenney Markan believes kids should be taught social skills in much the same way they are taught math and reading.

Bad Company

Many parents worry about the quality as well as the quantity of their child's friendships. "When she was in 1st grade, her supposed 'best friend' began calling her names and threatening to hurt her," says Mindy Miller. "My daughter wasn't allowed to talk to or even look at other girls in her class. It really crushed (压跨) her spirit. I told my daughter she didn't need a 'friend' like that."

"I'll bend over backwards to help my son get together with a friend I think is good for him," Adler-Tapia says. "I don't look at it as manipulation (操纵), just positive parental involvement. "

1.The example of Rachel and Abbie is used to show that ________.

A．childhood friendship is of great benefit to their growth

B．a positive friendship helps children solve emotional and physical problems

C．it is a proven（被证明的） fact that peer friendship is the most rewarding experience throughout life

D．Rachel missed her friend Abbie very much because of their separation of one weekend

2.The underlined word "detrimental" could be replaced by _______.

A．valuable          B．disappointing       C．accurate          D．harmful

3.We can learn from the passage that high-quality friendship most probably results from ______.

A．social skills and good study habits

B．school grades and classroom behaviors

C．academic success and social adaptation

D．positive parental involvement and social skills

4.From the last paragraph we can conclude that Dr. Robbie Adler-Tapia agrees that ______.

A．parents should regard making friends as something that just happens

B．it's wise for parents to support and encourage healthy peer relationships

C．parents only need to help their children to deal with difficult social situations

The First Americans

There was a time long ago when a land bridge connected Asia and North America．The first settlers in North America crossed this land bridge from what is now Siberia to Alaska．The people who made this initial crossing were probably following the animals they used for food．

Finally, the oceans rose and the land bridge between the continents disappeared．The settlers, who I shall call the "First Americans" , could not return to their homeland．  1  

For the next few thousand years, the First Americans moved south and east throughout North and South America．They made the journey all the way from Alaska to the southern tip of South America, a distance of more than 10,000 miles．    2   

In the far north, above the Arctic Circle, the First Americans became hunters of the ocean．  3 __  In the summer, they gathered berries and other plants．In the winter, they stayed in lodges much of the time preparing for the next summer．It was a hard life, but they learned to survive in these terrible conditions．
