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.

    The Crowne Plaza Hotel in Copenhagen is offering a free meal to any guest who is able to produce electricity for the hotel on an exercise bike linked to a generator (发电机). The idea is to get people fit and reduce their carbon footprint. Guests will have to produce at least 10 watt hours of electricity — roughly 15 minutes of cycling for someone of average fitness. Guests staying at Plaza Hotel will be given meal tickets worth $ 36 once they have produced 10 watt hours of electricity. The bicycles will have smart phones attached to the handlebars measuring how much power is being generated for the hotel.

    The plan, a world-first, will start on 19 April and run for a year. Only guests staying at the hotel will be able to take part. Frederikke Toemmergaard，hotel spokeswoman, said, “Many of our visitors are business people who enjoy going to the gym. There might be people who will cycle just to get a free meal, but generally I don't think people will take advantage of our programme.”

    Copenhagen has a long-standing cycling tradition and 36 % of locals cycle to work each day, one of the highest percentages in the world, according to the website visitcopenhagen. dk. US environmental website treehugger. com recently voted Copenhagen the world's best city for cyclists. “Because Copenhagen is strongly connected with cycling, we felt the bicycle would work well as a symbol of the hotel's green profile (形象).”

    If successful，the electric bicycle meal programme will be spread to all Crowne Plaza hotels in the UK, the hotel said in a statement.

    What are the biggest problems that society will have to deal with in the new age? There re diseases like AIDS and cancer. There's climate change, of course. And what about producing enough cheap food and energy for the world's growing population? Who's going to solve all these terrible problems? Yes, politicians and world leaders will have a big part to play. Yes businesses will need to create the economic wealth to pay for some of these things. But who's going to make a much greater difference to something like AIDS or climate change. It's going to be a scientist. It is the scientist who can turn some new bit of science into a new technology to solve these problems. If you like thinking about the world around you, why not become a scientist? It doesn't mean you have to wear a white coat and plastic glasses and spend all your time in a lab as most people often imagine! Scientists do all kinds of amazing things that are actually interesting!

    Military scientists develop not only new weapons but new military technologies that could help make wars out of date. Forensic(法医的) scientists work with the police to find quite small clues to catch criminals. Scientists work in schools and colleges as the teachers and professors who will train tomorrow's scientists. Don't think a scientist is far away! Maybe you like cooking? You could be a food technologist helping to keep fruit and vegetables fresher for longer. Perhaps sport is your thing? Do you know that most top athletes work with sports scientists in order or improve their performance? You could even be the science writer who gets to spend the life studying the latest advances and sharing them with the world.

    Looking for something to do for the rest of your life? My advice? Take a long and hard look at science. It is interesting and ever.

    A small insect is getting a lot of attention in the United States. The rusty patched bumblebee (大黄蜂) is the first of its species to be declared endangered in the lower 48 states—meaning every state except Alaska and Hawaii. The rusty patched bumblebee is named for a rust-colored line on its back.

    The U. S. Fish and Wildlife Service announced this month it was adding the bee to its endangered species list. The insects are "on the brink of extinction, " according to the service. It said the bees were once found in 28 states. But there now are only small populations remaining in 13 states. The government agency will make a plan to help the dying bees recover. The agency said that such a plan might help other insects,like butterflies.

    U.S. officials think land owners can take small steps to help the rusty patched bumblebee. They say land owners can be friendlier towards bees by using native plants in their gardens. The insects directly fertilize many kinds of fruit and vegetable crops. And they fertilize grain crops used to feed cattle and milk cows. It costs billions of dollars to duplicate the job the bees do for free. Land owners are also being urged to cut back on their use of pesticide products. The officials also suggest that gardeners leave their plants alone at the end of the summer instead of cutting them. That way, the bees will have a place to live over the winter.

    The Fish and Wildlife Service says the rusty patched bumblebee was added to the endangered species list partly because of habitat loss. Other reasons were disease, pesticides and climate change. Officials are worried that other bees will suffer, too. Another species of bees in Hawaii is also endangered.
