      The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gap(间隙)with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person's needs.

        Many Native Americans value silence and feel it is a basic part of communicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is speaking and suddenly stops, what maybe implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.

        Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person in authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.

Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient's silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.

    In one of the old buildings near our school,one could see an old man sitting by a large window on the first floor,His name was James.During the three years at school,I had hardly ever found him missing from his usual position.

He was a high-ranking government official and lived happily with his wife .Once there was a bus accident,in which a number of passengers were seriously injured and taken to the hospital for treatment.James was responsible for the rescue operation.It was a big hospital,but James was shocked to notice how ill-equipped it was.There was no enough life-saving drugs and life-supporting equipment.The injured and their companions had to struggle there .James attempted to help .However,though he emptied his pockets,many of them died that day.

That was a turning point in his life.He made a decision to devote his life to helping others,particularly the poor and needy patients and their companions.He began to spend much of his income on these people.Since this required much time and energy,he found it difficult to fulfill his official duties and therefore chose to retire,which,in turn,reduced his income considerably.

His wife was deeply worried.Most of the time,James was out and paid least attention to home affairs.Meanwhile,as he was spending a lot helping others,she had struggle even to meet the household expenses.Though she was not against his helping the poor,she urged him not to ignore his own home and life,but it had no effect on him.She decided to leave him ,never to return.Though he continued his work, this was a great blow and did serious harm to his health and enthusiasm and he was soon forced to stay indoors.That was when he took his position by the window,spending his time looking outside.

    A few weeks after my graduation,I returned to school,only to find the building gone.I heard that they were torn down.Everyone left except James.He refused to go and the next morning,he was found at his usual place by the window,dead.

    The average（平均的）American child spends three to five hours a day watching TV. In 1961, the average child began to watch television at age three; however, today it is nine months. Yet, most parents think that television has bad influence on their children. For example, in the early 1970s, my parents believed that my bad eyesight was the result of sitting too close to the screen, and they therefore made my stay at least six feet from it. Today, most people have no such worry, but many new ridiculous (荒谬的) sayings have appeared:

      *TV makes kids stupid. Many children watch more educational programs when they are pre-schoolers. When they grow up, they can read more books and have much better ideas to solve difficult problems than other children.

     *TV makes kids violent. The real story is not so simple. Hundreds of studies show that watching violence on TV makes children more aggressive (好斗的). But a study of over 5,000 children also finds that some positive programs make children kinder. The problem is that kids are increasingly watching shows with violence instead of those suitable for their age.

      *Sitting around watching TV makes kids overweight. An experiment finds that when children watch less television, they do lose extra weight; however, reducing their television time does not make them more active. The real problem lies in snacking (吃零食). A widespread habit for kids, and junk-food advertisements.

      *TV helps kids get to sleep. The opposite is true. The more television children watch, the more likely they are to have irregular sleep and nap (小睡) patterns. Allowing kids to watch television is part of the problem, not the solution.

    Are you interested in some of the most popular brands such as Beats headphones, True Religion jeans, and UGG shoes? They are also expensive. But some experts say they are not much better than cheaper brands.

    For example, Jim Wilcox works for Consumer Reports. He tested all kinds of headphones. He says that $80 Koss Pro headphones provide basically the same quality and comfort as Beats. So why do people pay twice or even 10 times as much for the hottest brands?

    Experts say it's because fashionable, expensive brands send a message. Brands say “I belong” or “I can afford it.”

    Some people think that expensive brand names are worth the price. They say that some designer clothes are really top quality and that they last longer than cheaper brands. Some teenagers choose to wear popular brands because these brands make them feel good about themselves.

    Alexandra Allam, 17, likes to buy brand-name products. “I'd rather spend the extra money to get something I know I'll be satisfied with,” she says. Her friend Emmy Swan agrees, saying “As long as you can afford it, it seems reasonable to buy what you want.” But not all teenagers agree. “Spending hundreds of dollars for designer sunglasses is stupid and unreasonable,” says Daniel Steinbrecher, 16. “It's fake (假的) happiness.”

    People who are against wearing expensive brand names say that many designer brands aren't any better. “It's wasteful to buy things just because they are popular,” says Edmund Williams, 15. “You'll feel better if you buy things because you like them. If you have extra money to spend, it would be better to give it to people in need.”

    One morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.

    Though he was tired, Howe slept badly. He turned and turned. Then he had a dream. He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine. When he tried to do so, Howe ran into the same problem as before. The thread kept getting caught around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised. But suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that he had just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the simple idea that finally made Howe design and build the first really practised sewing machine.

    Elias Howes was not the only one in finding the answer to his problem in this way.

    Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.

    To know the value of dreams, you have to understand what happens when you are asleep. Even then, a part of your mind is still working. This unconscious(无意识的), but still active part understands your experiences and goes to work on the problems you have had during the day. It stores all sorts of information that you may have forgotten or never have really noticed. It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake. However, the unconscious part acts in a special way. It uses strange images which the conscious part may not understand at first. This is why dreams are sometimes called “secret messages to ourselves”.
