Often a nickname is a shortened form of a person's name, and it can also be a descriptive name for a place or a thing. Many American cities have nicknames. These can help build up an identity, spread pride among citizens and build their unity. Nicknames can also be funny.

    Los Angeles, California is the second largest city in population, after New York City. Los Angeles has several nicknames. One is simply the city's initials, L.A. It is also called the City of Angels because Los Angeles means "the angels" in Spanish.

    Los Angeles often has warm, sunny weather. So another nickname is City of Flowers and Sunshine. New York is called The Big Apple. So Los Angeles is sometimes called The Big Orange because of the fruit that grows in that city's warm climate.

    The American movie and television industries are based in Los Angeles. So it is not surprising that it is called The Entertainment Capital of the World. Many films are made in the area of Los Angeles called Hollywood. Millions of people visit the area. No trip to Los Angeles is perfect without seeing the word "Hollywood" spelled out in huge letters on a hillside.

    Many movie stars live in Los Angeles. The city is sometimes called Tinseltown. This nickname comes from the shiny, bright and often unreal nature of Hollywood and the movie industry.

    Another nickname for Los Angeles is La-La Land, using the first letters of Los and Angeles. This means a place that is fun and not serious, and maybe even out of touch with reality.

    A good place for watching unusual-looking people is Venice, an area on the west side of Los Angeles. A system of waterways designed after the Italian city of Venice has been built there. Many people love Los Angeles for its warm sunny weather, beautiful mountains and beaches, and movie stars. That includes Randy Newman, who sings about his hometown.

    On the whole, Los Angeles is growing attractive just for its rich nicknames.

    Jolly Joe always arrived at my neighborhood at exactly half past noon. The clang (叮当声) of the bell on his red and black truck was then the sweetest sound in the world. Brightly colored stickers advertising his amazing kinds of treats could be found on all sides of his truck. The whole neighborhood would magically come to life.

    Holding a nickel (五分镍币), I'd run to the back of the vehicle, where children were already gathering. Jolly Joe would jump out of his truck, the sun shining on his hair. He was an older man, short and round, with a pleasant face and a welcoming smile.

    I don't know how, but he knew us all by name, as well as which treats we preferred. My favorite was the Buried Treasure. By eating all the ice cream, you'd discover the treasure inside: a lion, a dog or even a funny clown — printed onto a plastic stick.

    When it was finally my turn, he'd put his arm deep inside one of the boxes, and pause (停顿) for a moment, a puzzled look crossing his face. Then, suddenly, he'd pull it out: the Buried Treasure! I couldn't wait to enjoy the cool, sweet ice cream.

    As quickly as he arrived, it was time for Jolly Joe to go, leaving behind laughing, excited children with sticky hands and faces. Soon the sound of his clanging bell would slowly disappear in the distance.

    I always hated to see Jolly Joe go, because I knew the rest of the day would be as hot and boring as before. But I took some comfort in knowing that the next day he'd come round the corner at half past noon and once again spread his magic.

    It all started in 2013, when Shea Stollenwerk, then eight years old, asked for a new hand for Christmas. Shea was born with a partial right hand, which restricts her ability to do things that other kids take for granted.

    “My mom went online”, says Shea, who lives in Muknowango, Wisconsin. Shea's mother, Ranee, soon learned about a community of artists, designers, and scientists who are making big breakthrough with artificial hands.

    Frankie Flood, a professor at the University of Wisconsin in Milwaukee, was among the designers who saw Ranee's online request. Flood obtained help from fellow professor Adeam Blair and their students, who were learning how to make designs using a 3-D printer. “We made a mold(模子) of Shea's hand out of plaster(石膏), and then we 3-D scanned her hand,” Flood says.

    While being fitted in Flood's laboratory, Shea got to choose the color of her new hand. She went with bright pink. She now has a pink hand, a purple hand, and a purple and pink one, and can do things that she couldn't do before, like peeling potatoes, picking up objects, and catching a ball.

    Flood and his team have since built hands for six other local children. Indirectly, they have helped dozens more by posting their designs online so that people around the world can print them out. Flood is also working on artificial legs for military soldiers who were injured on the battlefield. “Without a covering, the artificial leg is kind of ugly and plain,” Flood says. “Soldiers want something that will restore the shape of their legs and make them look cooler when they're playing sports.”

    As for Shea, the aspiring musician can now play her violin with the help from an adaptive device that Flood's team created. “Nothing is ever going to hold her back,” Shea's father, Steve, told a local reporter.

    How could we possibly think that keeping animals in cages in unnatural environments -mostly for entertainment purposes - is fair and respectful? Zoo officials say they are concerned about animals. However, most zoos remain “collections” of interesting “things” rather than protective habitats.

    Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes. Zoos claim to educate people and save endangered species, but visitors leave zoos without having learned anything meaningful about the animals' natural behavior, intelligence, or beauty. Zoos keep animals in small spaces or cages, and most signs only mention the species' name, diet, and natural range.

    The animals' normal behavior is seldom noticed because zoos don't usually take care of the animals' natural needs. The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise. This results in unusually and self-destructive behavior called zoochosis. A worldwide study of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.

    Furthermore, most animals in zoos are not endangered. Captive breeding(圈养繁殖) of endangered big cats, Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot about their captive breeding programs because they do not want people to worry about a species dying out. In fact, baby animals also attract a lot of paying customers. Haven't we seen enough competitions to name baby animals?

    Actually, we will save endangered species only if we save their habitats and put an end to the reasons people kill them. Instead of supporting zoos, we should support groups that work to protect animals' natural habitats.

    Much older than the Great Wall, Stonehenge is one of the world's most fascinating (迷人的), but least understood historical sites (遗址). Every year, thousands of tourists come to admire Stonehenge's beauty and to wonder about how and why it was built.

    Stonehenge was produced by a culture that left no written records. Though there are many guesses, it is still a mystery why stone-age man moved such heavy stones over 380 kilometers from where they were made.

    At that time, people had only basic wooden tools. To move the stones they probably used tree trunks (树干) to roll them along.

    Some historians believe that Stonehenge was a temple, the site of ancient sacrifice(祭祀). Others believe it was perhaps a giant sundial (日冕) to tell the time. Stonehenge could have been a burial ground(墓地) from its earliest beginnings, because human bone dating from as early as 3000 BC was found there. Whatever its ancient use was, the stones have always been a source of fascination for British people. One record from 1135 said the great stones were carried to England by giant magical creatures!

    In modern times Stonehenge has become a huge hit with tourists. When Stonehenge was first opened to the public it was possible to walk among and even climb on the stones, but the stones were circled with ropes in 1977 as a result of serious erosion(侵蚀). Visitors are no longer allowed to touch the stones, but are able to walk around from a short distance away. What's more, visitors can make special bookings to get into the stones throughout the year.
