Throughout the history of the arts, the nature of creativity has remained constant to artists. No matter what objects they select, artists are to bring forth new forces and forms that cause change—to find poetry where no one has ever seen or experienced it before.

    Landscape is another unchanging element (元素) of art. It can be found from ancient times through the 17th­century Dutch painters to the 19th­century romanticists (浪漫主义艺术家 ) and impressionists. In the 1970s Alfred Leslie, one of the new American realists, continued this practice. Leslie sought out the same place where Thomas Cole, a romanticist, had produced paintings of the same scene a century and a half before. Unlike Cole who insists on a feeling of loneliness and the idea of finding peace in nature, Leslie paints what he actually sees. In his paintings, there is no particular change in emotions and he includes ordinary things like the highway in the background. He also takes advantage of the latest developments of color photography to help both the eyes and the memory when he improves his painting back in his workroom.

Besides, all art begs the age­old question: What is real? Each generation of artists has shown their understanding of reality in one form or another. The impressionists saw reality in brief emotional effects, the realists in everyday subjects and in forest scenes, and the Cro­Magnon cave people in their naturalistic drawings of the animals in the ancient forests. To sum up, understanding reality is a necessary struggle for artists of all periods.

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

    We've all been blamed (责备) wrongly sometimes in our lives. How do we deal with it? Not with anger, hurt and tears, but in a collected way…

    If you are wrongly blamed, let others know of the true state of things at once. Do it calmly and clearly — if you lose your temper, people will stop listening or become defensive.

    If you don't find a sympathetic ear, find a person who will hear you out — a teacher, a parent, a friend, or a brother or sister who believes in you.

    If you've been in trouble before, it may be easy for people to doubt you. So win your respect back in their eyes by behaving with honesty.

    If what you are blamed for is something unimportant, sometimes it's better to smile it off.

    If you've been blamed for something serious, it's important to put your side of the story forward quickly and truthfully.

    Just remember:

    Respect your friends' secret if you don't want to be wrongly blamed for making them known.

    Don't blame others without first getting proof of their wrong doing.

    Putting the blame on someone else for what you have done wrong is weakness. Admit your mistake quickly.

    If someone else is wrongly blamed, stand up for that person.

    Don't pass the responsibility to others.

    There are many reasons why I encourage people to travel, and I know that the experience will make one a better person.

    I remember when I was travelling I began to know the world better. The world is not just about me, my small town and home. Although you will meet different people from all over the world, you will realize that people are similar in their dreams, hopes and feelings. Enjoy exploring the different cultures, and you will also find that people are different in some of the things they do and how they live. Once you understand their ways, it need not be strange or scary. Often we read stories about other cultures in books. Only when we visit their areas do we find that those stories are something wrong.

    One thing you may find out is that there are problems all over the world. We can't just get money to send to these areas and hope that will work them out. The world should get involved（干预）and help wherever there are problems. People everywhere should be given a chance. It is so easy to ignore this if one does not travel and explore. One can look around and see that so many people have many challenges worse than ours. One can realize that sometimes our biggest problems are not that big after all.

    On your journey you will meet lots of new friends. Talking to strangers and finding about their lives is a great way to spend your time. you will certainly be more confident after having to cope with problems and make many decisions along the way.

    When you travel, you have to be on your own in some situations. You will surprise yourself by how well you can do that. All your special experiences could make an interesting book to read. It would be filled with all your adventures and special memories.

    Traveling around and seeing so much happening in the world around us is a wonderful experience. If we could all just travel a little more and share our experiences, we would all be better people and the world would be a better place.

    Genetic engineering, in its broadest definition, means to control a species so that a particular trait is increased in the population. A trait is how an organism (有机体) looks or acts or what it does. Having brown eyes is a trait. Flying in circles is a trait. Climbing trees is a trait.

    The earliest forms of genetic engineering occurred on farms. People selected seeds from plants that had more fruit production or tastier leaves than other plants of their types. Then they chose to save the seeds from the best of that group to sow the next year. So, year by year, the farmers produced better and better crops. This type of activity probably has been going on since mankind first settled in villages and began making a life for themselves in one location, about 12,000 years ago!

    The same sort of thing would have also happened with animals. For example, people chose to eat the animals that didn't have favorable traits and let the animals with the favorable traits reproduce. It was thousands of years before mankind figured out how plants and animals reproduce themselves. With this knowledge, people could pollinate (授粉) plants by hand or keep a pair of animals together in order to deliberately cause an increase in a favorable trait.

    It was only in the last 250 years that scientists began figuring out chromosomes (染色体) and genes and the role they play in the way one generation passes its traits on to the next. And it's only been in the last 30 years that scientists have been able to cut out specific genes from one organism and put them in another. It is this 30-year-old technology that is described by the narrow definition of genetic engineering. Mankind has long been able to have a deliberate impact on the world around him. He now possesses the tools to deliberately impact himself. Some people are afraid of what might be done with that power.

    A university in southwest China's Chongqing City set up a reading room as part of a campaign(活动)that stops students from taking their mobile phones with them in case the device distracts(使分心)them from focusing on their studies.

    Reportedly a student named Hu Xiaopeng taking part in the campaign studied 530 minutes without using his mobile phone. Unlike Hu, another one picked up his mobile phone in less than 20 minutes. "Having seen many students use their mobile phones in the library, a habit that shortens their study time and negatively affects their learning, we decided to open this reading room," said Zhang Shuran, the person responsible for the project at the university.

    Zhang added that students can keep their phones in appointed bags with numbers on them. The bags are placed on a desk near the door of the reading room. "Staff members at the reading room will check the phones when there's a call," said Zhang, adding that they will inform students when their parents or teachers call them, but will not tell students if an unknown person is calling or when there is a text message. Based on the time students hand in their phones when they come to the reading room and the time they get them back when they leave the room, Hu Xiaopeng from College of Animal Science and Technology of the university set a record of the longest time. Hu spent 530 minutes studying without using his phone. Though feeling somewhat surprised, Hu said, "It's bad to keep mobile phone with you when you are reading or studying."

    The campaign has attracted nearly 200 students since it was started a week ago. Some Internet users praised the campaign. One user named Liu Jingchang said, "It's good. I don't bring my phone when going to the library in case I get distracted."

    who doesn't love sitting beside a cosy（舒适的）fire on a cold winter's night ? Who doesn't love to watch flames (火苗) curling up a chimney ? Fire is one of man's greatest friends, but also one of his greatest enemies. Many big fires are caused by carelessness. A lighted cigarette thrown out of a car or train window or a broken bottle lying on dry grass can start a fire. Sometimes, though, a fire can start on its own. Wet hay (草) can begin burning by itself. This is how it happens: the hay starts to rot (腐烂) and begins to give off heat which is trapped inside it. Finally, it bursts into flames. That's why farmers cut and store (贮存) their hay when it's dry .

    Fires have destroyed whole cities. In the 17th century, a small fire which began in a baker's shop burnt down nearly every building in London. Moscow was set on fire during the war against Napoleon. This fire continued burning for seven days . And, of course, in 64 A. D. a fire burnt Rome. Even today, in spite of modern fire - fighting methods, fire causes millions of pounds' worthy of damage each year both in our cities and in the countryside. It has been wisely said that fire is a good servant but a bad master.
