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.

    Well-known for historic architecture and chocolates, Lviv, Ukraine's official capital of culture, looks, smells, and tastes like the best of Europe. Indeed, its western flavor has earned it the title "Little Paris of Ukraine".

    For centuries Lviv, located 50 kilometers from the Poland-Ukraine border, was an important stopping point on the main trade routes between the east and west. During the Renaissance, the city could afford Italy's finest architects because every merchant passing through was forced to stay and sell their goods for at least two weeks. "It was a very smart move to collect money from them," said Yaroslav Hrytsak, a local historian, adding, "It kept the wealth in the city, and that wealth has been transformed into architectural richness."

    Many historic buildings remain but Lviv's prosperity didn't survive its bloody history. Over the centuries, the city fell under the rule of Poland, Austria, Austria-Hungary, Russia and the Nazi Germany. In addition, both Sweden and Turkey tried unsuccessfully to conquer the city. Then for almost half a century Lviv was ruled by the Soviet Union (苏联). With that, the city was condemned to relative obscurity(无闻). But recently things have started to change. Lviv experienced a sudden 40% increase in tourism in early2010, which was the highest rate in Europe. Just last month, its gates opened even wider, when Lviv became a host city for the Euro 2012 football championships.

    So how has this happened? With the Soviet collapse, some saw new opportunities for reviving Lviv's former wealth and fame.

    Limelight networks is a US-founded company. It's one of many digital tech firms to have opened offices in Lviv over the past few years. "It had good growth and experience in the US, however, the company needs more talent to do the new cool projects and products for our customers. This is why we're here in Ukraine." said CEO of Limelight networks.

    Lviv's unexpected abundance of I.T. talent is in fact a legacy(遗产) of the former Soviet Union. To help the military, many Soviet universities focused on turning out world-class engineers and Lviv's university is still producing them. Now, the city is home to 23 higher education institutions. It's clear that the city of Lviv does not intend to remain a hidden jewel for much longer.

    When it comes to thrilling places to travel to, the nation of Thailand has got to be at or near the top of the list. The beaches of Thailand are simply amazing. Here is a look at the four best beaches in all of Thailand.

    Maya Bay

    This small beach attracts some huge crowds, but it is still worth a visit thanks to what is widely regarded as some of the best scenery in the entire country. The Maya Bay Beach is located on a small island and is only accessible via boat or passenger ferry.

    Lamai Beach

    For the traveler looking for an unforgettable beach experience during their visit to Thailand, a trip out to Lamai Beach in Samui is a must. The sandy areas are long and wide with plenty of room for everyone. The water is inviting and easy to access.

    Patong Beach

    Patong Beach is not only one of the most beautiful and popular beach in Thailand, but it is the largest beach on the popular island of Phuket. The soft white sand is a great place to relax. Some of the many great activities that travelers can participate it. during a visit to Patong Beach include jet skiing, kayaking, surfing, diving, snorkeling(浮潜) , swimming, and more.

    Haad Rin

    Haad Rin is one of the most popular party spots in the country, for both locals（当地人） and travelers. All month long, during most parts of the year, there are some exceptional entertainment, eating, and socializing opportunities.

    After decades of cat-and-mouse between athletes and the word anti-doping agency (WADA), athletes found what they must have believed to be the ultimate (终极的) doping agent: their own blood. To enhance athletic performance with your own blood, you draw your blood and store it in a freezer. Your body compensates by creating more blood. Then, months later, just before a competition, you can re-inject (注射) the old blood for a boost. As the red-blood-cell count goes up, so does an athlete's ability to absorb oxygen. The more oxygen you get with each breath, the more energy your body is able to bum and the better you are able to perform.

    Although the enhancement is small compared to actual drugs, it can be the difference between a gold medal and a silver medal. Best of all, "extra blood" was never something WADA tested for.

    But WADA wasn't going to sit by and be fooled. What it came up with in response might be a solution to stop doping once and for all: an athlete biological passport (ABP). The idea is to record some biological features of an athlete through testing done at regular intervals. The biological passport's partial implementation (实施)—recording blood and steroid levels—began in January 2014.

    When all necessary biological features are finally combined, WADA will no longer need to worry about finding new methods to detect a drug. It will only have to detect (检测) resulting changes in the body. In the case of blood doping, if the athlete's normal red-blood-cell count is, say, 47%, but then is found to be 51% after a competition, cheating may have been involved.

    WADA is confident that the biological passport could even prevent genetic changes—the ultimate, ever-lasting enhancement—which are surely coming next. If an athlete inserts a performance enhancing gene, it will probably leave detectable changes in the body, that would differ from the athlete's feature in the biological passport.

    It's school time again! You're probably feeling excited and maybe a little sad that summer is over. Some kids feel nervous or a little scared (害怕的) on the first day of school because of all the new things: new teachers, new friends, and even a new school. Luckily, these "new" worries only stick around for a little while. Let's find out more about going to a new school.

    Most teachers kick off the new school year by introducing themselves and talking about all the stuff you'll be doing that year. Some teachers give students a chance to tell something about themselves to the rest of the class, too. When teachers do the talking on the first day, they often go over classroom rules and school rules so you'll know what's allowed and what's not. Please pay close attention.

    You might already know a lot of people in your classes on the first day, but it's a great day to make new friends, so try to say hello to kids you know and new ones that you don't. Make the first move and you'll be glad, and so will your new friends!

    Seeing friends you haven't seen in a while can make the first day a good one. You can make the day feel special by wearing clothes that you really like. Maybe you got a great T-shirt on one of your vacations, or a pair of sneakers (运动鞋). It also can make you feel good to be prepared and have all the things you need, such as pencils, folders, and whatever else you'll be needing. But make sure that you pack them the night before in case you don't have time in the morning.

    I'm learning to drive in Switzerland. I think it will be a good idea to learn now because I have plenty of free time and am earning a little money to pay for lessons. I never learnt when I lived in the UK, so luckily driving on the "wrong" side isn't a problem.

    However, there are a lot of rules to remember. When you see a road to your right and there are no white lines on the ground, the cars to your right have the right to go before your car and you have to stop for them. In practice, lots of people forget this and cars either wait for each other while both drivers try to remember what to do, or beep (鸣喇叭) at each other if both try to go at the same time!

    When you drive round a roundabout, you should check all your mirrors. To remember how to do this, I often count them aloud—one, two, three—then a second glance at your blind spot when you're in the roundabout. One friend came driving with me and after about an hour asked why on earth I was counting. He had passed his test so long ago, he couldn't remember ever having to check three mirrors!

    Driving still seems scary to me so I drive quite slowly. I also don't know the countryside roads very well and don't know what's coming up round the comer or over the next hill. I drive slowly so I feel safe, but my driving instructor tells me to speed up or cars will bump into me from behind or try to overtake somewhere dangerous. So driving slowly is just as dangerous as driving fast!

    I'm not a very practical person so learning to drive has been a challenge. I don't have a lot of confidence and find it quite demotivating to do something that doesn't come naturally to me. To make driving more fun and interesting, I learn in Swiss German, so my instructor gives me instructions in Swiss. This way I've tricked myself into enjoying driving and hopefully will pass the test!
