Throughout the history of the arts, thenature of creativity has remained constant to artists．Nomatter what objects they select, artists are to bring forth new forces andforms that cause change—to find poetry where no one has ever seen orexperienced it before．

Landscape (风景) isanother unchanging element of art．It can be found from ancient timesthrough the17th-century Dutch painters to the 19th-century romanticists andimpressionists．Inthe 1970s Alfred Leslie, one of the new American realists, continued thispractice．Lesliesought out the same place where ThomasCole, a romanticist, had producedpaintings of the same scene a century and a half before．UnlikeCole who insists on a feeling of loneliness and the idea of finding peace innature, Leslie paints what he actually sees．In his paintings, there is no particularchange in emotion, and he includes ordinary things like the highway in thebackground．Healso takes advantage of the latest developments of color photography to helpboth the eye and the memory when he improves his painting back in his workroom．

Besides, all art begs the age-oldquestion: What is real? Each generation of artists has shown theirunderstanding of reality in one form or another．The impressionists saw reality in briefemotional effects, the realists in everyday subjects and in forest scenes, andthe Cro-Magnon cave people in their naturalistic drawings of the animals in theancient forests．Tosum up, understanding reality is a necessary struggle for artists of allperiods．

Over thousands of years the function ofthe arts has remained relatively constant．Past or present, Eastern or Western, thearts are a basic part of our immediate experience．Many and different are the faces ofart,and together they express the basic need and hope of human beings．

    Researchers in the psychology department at the University of California at Los Angeles (UCLA) have discovered a major difference in the way men and women respond to stress.This difference may explain why men are more likely to suffer from stress related disorders.

    Until now，psychological research has maintained that both men and women have the same “fightorflight” reaction to stress.In other words，individuals either react with aggressive behavior，such as verbal or physical conflict (“fight”)，or they react by withdrawing from the stressful situation (“flight”)．However，the UCLA research team found that men and women have quite different biological and behavioral responses to stress.While men often react to stress in the fightorflight response，women often have another kind of reaction which could be called “tend and befriend.” That is，they often react to stressful conditions by protecting and nurturing their young (“tend”)，and by looking for social contact and support from others—especially other females (“befriend”)．

    Scientists have long known that in the fightorflight reaction to stress，an important role is played by certain hormones(激素) released by the body.The UCLA research team suggests that the female tendorbefriend response is also based on a hormone.This hormone，called oxytocin，has been studied in the context of childbirth，but now it is being studied for its role in the response of both men and women to stress.The principal investigator，Dr.Shelley E．Taylor，explained that “animals and people with high levels of oxytocin are calmer，more relaxed，more social，and less anxious.” While men also secrete(分泌) oxytocin，its effects are reduced by male hormones.

    In terms of everyday behavior，the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed.They may phone relatives or friends，or ask directions if they are lost.

    The study also showed how fathers and mothers responded differently when they came home to their family after a stressful day at work.The typical father wanted to be left alone to enjoy some peace and quiet.For a typical mother，coping with a bad day at work meant focusing her attention on her children and their needs.

    The differences in responding to stress may explain the fact that women have lower frequency of stressrelated disorders such as high blood pressure or aggressive behavior.The tendandbefriend regulatory(调节的) system may protect women against stress，and this may explain why women on average live longer than men.

    As computers become more popular in China, Chinese people are more and more depending on computer keyboards to input Chinese characters(汉字). But if they use the computer too much, they may end up forgetting the exact strokes(笔画) of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more widely spread among university students. Almost all their homework and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being used more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.

    'When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it.'

    'I'm not in the mood to write when faced with a pen and paper.'

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, headmaster of a famous primary school in the capital said, 'Chinese characters enjoy both practical and aesthetic (审美的)value. But those characters typed with computer keyboards only keep their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's feelings. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them.'

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory（必修的）and in universities, some professors are asking students to turn in their homework and essays written by hand.

    Fairy tales perform many functions. They entertain, encourage imagination and teach problem—solving skills. They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI (artificial intelligence) can take to its cold, mechanical heart.

    The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called “Quixote” (堂吉诃德). It collects story plots from the Internet and then uses those stories to teach robots how to behave.

    The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the store keeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives(指令), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robot will learn the moral way to behave on that occasion.

    Quixote would work best on a robot that has a very limited function. It's a baby step in the direction of teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means.

    Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.

    Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to "speak" with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees—anywhere at all!

    Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers.

    In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too.

    At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, "Here we are in the middle of Virginia and we're giving students a window on the world. They can see everything and do everything."

Dear Students,

    I am delighted to be your guest.

    I would like to tell you about myself. I have been a news reporter for the past fifteen years. I chose this job so I could travel the world, but the job has taught me many unforgettable lessons. The work is sometimes difficult. I have seen famines, wars, earthquakes, poverty and death. But I have also seen courage, hope and happiness.

    In India, I visited a city where there were many homeless children. Some were as young as four years old. They lived in the streets and survived by begging or stealing. But then a wonderful lady called Rosa opened a home for them. Within one year, she was looking after two hundred children. She clothed them, fed them, and taught them. She gave them hope.

    Another time, I was in Turkey after a terrible earthquake, in one place. I found an old lady whose house was in ruins, her son was missing and rescuer workers said there was no chance that he was still alive. But the old lady did not give up hope. For four days, she moved heavy stones one at a time by herself. She did not stop until she found her son. He was alive.

    Here in China, I met a young boy with a serious condition. He had undergone twenty operations and spent nearly his whole life in hospital. I thought he would be sad, but when I met him, his smile was so warm and welcoming.

    In life, we need role models that we can admire and learn from. When my life is difficult, I try to remember the courage and goodness of these three people.
