The Chinese word "Shanzhai" means a small mountain village, but now it becomes an accepted name for fakes (假货), after "Shanzhai Cell-phones" produced by small workshops in southern China became popular in the mainland market over the past two years. Besides (除……之外，还有)"Shanzhai" electronic products, there are "Shanzhai" movies, "Shanzhai" stars and even a "Shanzhai" Spring Festival Gala, a copy of the 25-year-old traditional show presented by CCTV on Chinese Lunar New Year's Eve.

    "Shanzhai" has become a culture of its own, meaning anything that imitates something famous. In Chongqing, "Shanzhai" version "Bird's Nest（鸟巢）" and "Water Cube（水立方）" woven by farmers with bamboo attract(吸引) wide attention from tourists. Both are copies of the famous Olympic buildings in Beijing.

    A literature critic said that taking the "Shanzhai" Gala as an example, when the traditional CCTV program becomes less and less attractive to the audience, the "Shanzhai" version appears timely to attract people. "Although it is often connected with poor techniques and operation, 'Shanzhai' culture meets the psychological needs of common people and could be a comfort to their minds," he said.

    To the mainstream（主流） culture, the rise of "Shanzhai" culture is a challenge and a motivation（推动）. People believe different kinds of cultures developing together is a perfect way and it is for the public to choose.

    Held in Valencia, La Tomatina is a tomato-throwing activity that causes the number of people to increase to more than 40,000 in a town of just 9,000 persons.

    The festival takes place on the town's main square. At 11 o'clock, the third Wednesday in August every year, a large pole(杆) with a ham tied to the end of it is raised into the air, and there is a mad climb as people struggle against each other to pull it down. Once this is achieved, a rocket goes skywards and more than 100 tons of ripe tomatoes are tipped from trucks to the waiting crowd. For precisely one hour, until a second rocket is fired, everyone joins in a cheerful tomato battle.

    La Tomatina began in 1945, but it is not known why. Locals have many theories, including the popular tale of angry townsfolk attacking city councilmen(议员) during a town celebration. However, it could also have started because of anything from an anti-France protest or simply a fun food fight between friends. Whichever way it started, the townsfolk of Valencia enjoyed it so much that it was repeated year after year, finally becoming an officially recognized celebration in 1952. Despite being cancelled briefly during the 1970s for having no religious significance, it has returned every year since then.

    Most people come for the day, arriving on the morning train from Valencia and heading back in the afternoon. But if you want the full La Tomatina experience, stay for the week-long celebration which involves music, dancing, parades and fireworks. The night before the fight, a cooking competition is held where women traditionally dress in white, and men without shirts altogether.

    Protection for the fight is recommended—wear old clothes and shoes and a pair of glasses to protect your eyes. What you don't bring to La Tomatina is also important. The crazy tomato-throwers attack each other with all their strength: cameras are seen as positive invitations to throw at the owner.

    Dubai(迪拜)is one of the economically richest places in the world. With its numerous malls, hotels, and beautiful beaches, Dubai has always been a popular holiday destination. This city was visited by around 5 million tourists each year. The government wanted to increase this number to 15 million. However, Dubai has only 45 miles of coastline, which is nowhere enough for so many people. To solve this problem, an island that looked like a palm tree was built in 2006, and named the Palm Jumeirah.

    The plan for the island was extraordinary. It was to host several hotels, shopping malls, restaurants, and homes. Although the initial plan was to build the island from concrete(水泥), a decision was taken to create it from sand and gravel(砾石), so as to give it a natural look.

    To make sure that this project was a success, the best engineers from across the world were employed. Engineers from Holland formed the majority in this group. To begin with, the engineers calculated the strength of storms at sea, and also the expected amount of rise in water levels due to global warming. And then they found that, the proposed location for the island was neither very wide nor deep.

    One of the difficulties the engineers came across was to put sand on the sea bed to create the breakwater(防浪堤).Finding the right sand for the project was also a daunting task, as the sand from Dubai's deserts was too fine. Instead, sand from the sea was used, as it was coarser(粗糙). Once the breakwater was built, construction of the island began.

    The Palm Island are really impressive in terms of engineering. However, these projects are so large that they may have changed the ecology of the region. Also, an immense amount of money and resources go into maintaining the islands, which is a major concern at the moment. Only time will tell if building the Palm Islands was actually a good decision.

    If you live in Shanghai, Beijing or many other cities, you may see many orange bicycles on the streets these days.

    These bikes are owned by a company called Mobike. You can order a bike through an app on your phone. When you find a bike, you just scan a QR code （扫描二维码） on the bike so you can use it. You don't need to return the bike to a station- you can park it anywhere.

    China was known as "the kingdom of bicycles" about 30 years ago. But more people choose to drive cars and catch the subway these days. Bike rental（租凭的） services like Mobike are bringing bikes back.

    "Back then, I got the feeling that Chinese people were trying to be modern and push away the past. So they did not want to be linked with bicycles," said Ines Brunn, a German woman who runs a bike store in Beijing. "I do believe changes in people's tastes will shape new thinking about bikes."

    Online rental services are making biking more convenient, but it's still not easy to ride bikes in Chinese cities. Cars often take up bicycle lanes （道路）. Bikers have to ride next to cars in car lanes, which can be very dangerous.

    Beijing plans to build over 3,200km of new bike lanes. Drivers who drive in bike lanes will be punished. Traffic signs will be put up to better protect bikers.

    Before you make friends, you have to decide who you want to be your friends.

    Most people like to have friends who like to do the same kind of things they do.

    The quickest way to make a friend is to smile. When you smile, people think you are friendly and easy to talk to. It may not be easy at first to smile, but remember most people will stay away from a scaled or angry looking.

    One easy way to start a conversation with someone is to say something nice about him. Think about how great you feel when someone says something nice to you. Doesn't it make you want to keep talking to that person?

    Ask your new friends questions about themselves. Who's their favourite singer, where do they live, what do they do after school are all good questions to start a conversation. Make sure you have something to add to the conversation, too. Then someone asks you a question, do have an answer for it. There is nothing that will stop a conversation quicker than a shrug for an answer.

    Kids who show an interest in other kids and who are kind and friendly make good friends. Remember, everyone wants to be around people who like to do similar things and people who are nice to them.
