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．

    Hans Christian Andersen is a Danish writer famous for his fairy tales, many of which depict (描述) characters who gain happiness in life after suffering and conflict.

    Andersen's father was a poor shoemaker and his mother worked as a washerwoman. As a child he was highly emotional, suffering all kinds of fears and shame because of his unmanly interests. Encouraged by his parents, he composed his own fairy tales and arranged puppet (木偶) theater shows. At the age of 14, Andersen moved to Copenhagen to start a career as a singer—he had a beautiful voice. He succeeded in becoming associated with Royal Theater, but he had to leave it when his voice began to change. When casually referred to as a poet, he changed his plans and began to write plays, all of which were refused.

    In 1822, Jonas Collin, the director of the Royal Theater, gave Andersen a grant to enter the grammar school at Slagelse. In 1827, Andersen gained admission to Copenhagen University, where he completed his education. In 1828 he wrote a shot story on travel, a fantastic tale in the style of the German Romantic writer, E. T. A. Hofmann. He traveled widely in Europe and remained a passionate traveler all his life.

    As a novelist, Andersen made his breakthrough with The Improvisatore. The story described a poor boy's integration (融合) into society, an Ugly Duckling theme of self-discovery. The book gained international success and remains the most widely read of all his works.

    In his early collections, Andersen returned to the stories that he had heard as a child, but gradually he started to create his own tales. Most of Andersen's works were original. Only 12 of his 156 known fairy stories drew on folktales.

    The ugliness of the hero or heroine in his stories often conceals (隐藏) great beauty，which is revealed (揭示) after misfortune. Some of Andersen's tales reveal a positive belief in the victory of the good, among them, The Snow Queen and The Ugly Duckling, and some end unhappily, like the Little Match Girl. In The Little Mermaid the author expressed a longing for the ordinary life that he had never had. Andersen never married, and he died in his home in Rolighed in 1875.

    Sue Hendrickson is a self-taught fossil（化石）hunter. As a kid, Sue Hendrickson often walked with her head down. “People said, 'Look up. Smile!” she says. “Now, I realize I was born to look for things and just didn't know it.”

    Sue Hendrickson does more than look—she finds valuable things: Shipwrecks（沉船）with treasure, ancient sunken cities, and in 1990, she found Sue, the world's largest, most complete Tyrannosaurus rex（霸王龙）. Is Hendrickson lucky? Well, maybe. But she also knows how to look.

    “I limit the area where I'm going to look,” she says. No one knew the location of the sunken ship San Diego in the Philippines. For a year, Hendrickson and other researchers searched papers and sailors' diaries. “The descriptions of the ship's sailors led us to the wreck,” she says. The team also used a tool that can respond to metal. This tool found the San Diego. All the work paid off. The 400-year-old ship was complete, with valuable gold and silver coins.

    To find the dinosaur she calls “the biggest animal that ever walked on earth,” Hendrickson started with maps made to search for oil. What Hendrickson found was the largest and most complete T-rex found to date. The T-rex is 42 feet long with 200 bones! Because it is so complete, scientists were able to infer that Sue walked at about 6 miles per hour and did not run faster than 15 miles an hour. Before Sue was discovered, they thought T-rex was much faster. To learn more about T-rex Sue, go to the Field Museum in Chicago.

    There's plenty left to be found, Hendrickson says, including answers to mysterious such as how T-rex lived. “I tell kids that they need to grow up and work them out because all of us old persons haven't yet!”

    It's not easy being a teenager– nor is it easy being the parent of a teenager. You can make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is important to give your child the space he needs to grow while gently letting him know that you'll still be there for him when he needs you.

    Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use or careless driving, consider everything else open to discussion to help them grow up more independently. If your child is unwilling to discuss something, don't insist he tell you what's on his mind. The more you insist, the more likely that he'll clam up. Instead, let him attempt to solve things by himself. At the same time, remind him that you're always there for him should he seek advice or help. Show respect for your teenager's privacy (隐私). Never read his mail or listen in on personal conversations.

    Teach your teenager that the family phone is for the whole family, which can make them more mature. If your child talks on the family's telephone for too long, tell him he can talk for 15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation (节制). Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part-time job.

    Scientists Diego Kersting and Cristina Linares have found that some coral species are able to recover from harmful warming events through a unique survival strategy (策略)—known as "rejuvenescence" (新生)—among corals in the Mediterranean Sea. The findings represent some rare good news for corals around the world, which are facing numerous severe threats—most notably, climate change.

    "The main threats are climate change, overfishing, pollution and coastal urbanization," Kersting said. "But currently, climate change is probably the one causing the most coral cover declines. Warming stresses corals up to a point that may cause death. Some corals bleach (白化) before dying. Other corals do not bleach but die directly." He went on, "Our findings are significant because this survival strategy was only known from fossil corals that existed hundreds of millions of years ago. It is the first time that it has been found in a living coral. Thanks to our findings, we know now that some corals are able to recover, but unfortunately this is not enough in the current climate change context."

    For their research, Kersting and Linares monitored 243 colonies of the endangered reef-building coral Cladocoracaespitosa in Spain's Columbretes Islands Marine Reserve over 16 years, starting in 2002. The monitoring revealed that Cladocoracaespitosa in the Mediterranean uses rejuvenescence to cope with warming events. This process involves the polyps — or the individual coral animals in a colony—shrinking inward and abandoning their skeletons (骨骼) during warm periods, before rejuvenating at a later point. "What happens is that some polyps in a coral colony—sometimes just one— reduces completely its dimensions and partially retreats from its skeleton," Kersting said. "Once the stressful event is over, the shrunken or rejuvenated polyp recovers its size and builds up a new skeleton. Eventually, it begins to reproduce itself through budding and begins to cover the dead colony surfaces."

    He continued, "The results were very surprising because I started to observe colonies that were dead years ago, that were showing living parts many years after their death."

Bill Sumiel was having a tough Friday. It was October 2020, and the 71-year-old, who was dealing with kidney(肾)failure and had been on dialysis( 透 析 )for a few years, found himself away from home. 

He'd been diagnosed with diabetes(糖尿病) over 20 years before, which led to his kidney problems. He was on the transplant list, but no matches had yet appeared. So he continued with his treatments periodically. Without a ride lined up for Friday's do-over, Sumiel took Ubers to and from his appointment. 

Timothy Letts, 31, was driving to visit a friend when his phone received the request for Sumiel's ride home. When Sumiel got into his car, Letts could see that the older man was unenergetic but in good spirits. And as they set out to Sumiel's home, the pair got to chatting. During conversation, Sumiel revealed that he was searching for a kidney donor. Letts joked that he'd be a good donor candidate, given that he didn't drink or smoke. 

Sumiel agreed, though he didn't think much of it. Letts, however, couldn't stop thinking about it and it was always on his mind. So, Letts said:"I'd like to see if I could be a match to give you a kidney. "

"I was shocked, "Sumiel recalls. He was shaking so hard that he could barely write his name when they exchanged contact information. After the initial excitement, Sumiel started feeling less optimistic. He was touched by Letts's offer, but he wondered if it had just been an emotional moment. Would he hear from him? And what was the likelihood of a match?

But Letts was true to his word. He got in touch with Sumiel just a few hours later, and by the next week, Letts had contacted the kidney transplant program. After a series of testing, the results were in: Letts was an ideal donor, and he and Sumiel were a perfect match. 

In December 2021, 14 months after their chance encounter, Sumiel and Letts had their surgeries. It was a success. Today they live respectively and healthily and anticipate the day they can reunite.
