    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to.

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable.

    Good luck!

    Eddie, Aged 20

    When I started high school I was really nervous too, especially since I had been homeschooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    I am not going to lie. The first day is kind of frightening. But you'll get used to it. Don't be afraid of anyone; upperclassmen will pick on you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.

    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    Military scientists develop not only new weapons but new military technologies that could help make wars out of date.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.

    Attention from strangers is nothing new to me. Questions about my height is the center of almost every public interaction. My friends say my height is just a physical quality and not a personality aspect. However, when I reflect on my life, I realize that my height has shaped my character in many ways and has helped to make me who I am.

    I learned how to be kind. When I was younger, some parents in my neighborhood regarded me kind of dangerous because I was so much larger than other children of my age. I had to be extra welcoming and gentle simply to play with other children. Of course, now my coaches wish I weren't quite so kind on the basketball court.

    I learned the quality of not being too proud about myself. At 7 feet tall, everyone expects me to be an amazing basketball player. They come expecting to see Dirk Nowitzki, and instead they might see a performance more like Will Ferrell (successfully starred a professional basketball player). I have learned to be modest and to work even harder than my fellows to meet their (and my) expectations.

    I developed a sense of lightheartedness. When people playfully make fun of my height, I laugh at myself too. On my first day of high school, a girl dropped her books in a busy hallway. I got down to her level and gathered some of her notebooks. As we both stood up, her eyes widened as I kept rising over her. Astonished, she dropped her books again. Embarrassed, we both laughed and picked up the books a second time.

    All of these lessons have defined me. Looking back, I realize that through years of such experiences, I have become a confident, expressive person. Being a 7-footer is both a blessing and a curse (诅咒), but in the end, accepting who you are is the first step to happiness.

    Have you ever been into a cave? If not, please follow us and explore some of the most beautiful caves from around the world!

    Marble Caves

    Located in the center of Lake General Carrera, the Marble Caves in Chico, Chile, are only accessible by boat. The surrounding crystal clear waters allow visitors to see the rock formations beneath them while the rock ceilings above change color(depending on the writer levels and the season). The best time to visit: during sunrise and sunset, when the sun's rays light up the cave walls, making it an experience to remember.

    Reed Flute Cave

    Reed F1ute Cave known as "the Palace of Natural Arts" is located in the northwest of Guilin in southern China. The limestone cave offers a grand fairyland of stalactites(钟乳石), stone pillars, stone curtains, birds, plants and animals in fantastic shapes and colors.

    Fingal's Cave

    This incredible sea cave is located on the uninhabited island of Staffa in Scotland. The cave's size, shape, and naturally­arched(拱形的) roof combine with the waves to create strange sounds that enhance its cathedral­like atmosphere.

    The Blue Grotto

    The Blue Grotto is the symbol of Capri. It is a sea cave found on the coast of the island and is a well-known spot to all who visit the area. This cave is unique for its brilliant blue light which comes from two sources: the entrance to the cave and a bigger hole beneath the entrance. When viewed from inside the cave, the entrance appears as a brilliant white light just above the waterline, while the underwater hole, which is the larger source of light, provides a blue light.

    What makes a building ugly? Everyone's got their own opinion, so it's hard to say. Now, let's take a look at some of the world's worst buildings.

    The Torre Velasca

    The Torre Velasca in Milan is in the centre of Milan(Italy). The tower, which went up in the 1950s, is about 100 metres tall. Its design is actually a modern representation(代表) of a traditional Lombard castle, where the lower parts were narrower than the upper parts.

    The Mirador Building

    The Mirador Building in Madrid(Spain)was created by Dutch studio MVRDV and the Spanish architect(建筑师)Blanca Lleó.The building, which is a block of flats, opened in 2005. There is a large rectangular(矩形的)hole in the upper part of it, which is used by the neighbourhood as a meeting area and playground.

    The Prague TV Tower

    The Prague TV Tower is in Prague(the capital of the Czech Republic). It stands 216 metres high and looks a bit like a tall, thin space ship. Prague is famous for its architectural beauty, so when the tower was put up in 1985 by architect Vaclav Aulicky and engineer Jiri Kozak, many felt it didn't fit in.

    The Longaberger Basket Company

    The Longaberger Basket Company building is in Newark, Ohio(USA). The office block was opened in 1997 and looks like a very large basket. It's got seven floors and two handles(把手)at the top. The handles weigh about 150 tons. It may not be the ugliest building in the world but it's certainly one of the most unusual.

Flying High

    Barrington Irving landed his record-breaking light at age 23 and founded an educational nonprofit organization. His message for kids: "The only thing that separates you from scientists is determination, hard work and a strong liking for what you want to achieve." The secret, he believes, is having a dream in the first place.

    The moment of inspiration for Irving came at the age of 15 in his parents' bookstore. One customer, a professional pilot, asked Irving if he'd thought about becoming a pilot. "I told him I didn't think I was smart enough; but the next day he took me to the cockpit (驾驶舱) of the commercial airplane he flew and just like that I was hooked."

    To follow his dream, Irving Turned down a football scholarship to the University of Florida. He washed airplanes to earn money for a flight school and increased his flying skills by practicing at home on a $40 flight simulator (模拟) video game. Then another dream took hold: flying alone around the world. He faced more than 50 rejections for sponsorship before convincing some companies to donate aircraft components. He took off with no weather radar, no de-icing system, and just $30 in his pocket.

    After 97 days, 26 stops and dozens of thunderstorms, he touched down to a cheering crowd in Miami. "It was seeing so many young people watching and listening that pushed me into giving back with my knowledge an experience." Irving has been doing it ever since. He set up his non-profit organization, Experience Aviation (航空), aiming to increase the numbers of youth in aviation career. By bring challenging project-based learning, hands-on and other educational opportunities to school districts and local communities nationwide, the organization has excited the hearts and minds of youth. "We want to create chances for students to accomplish something amazing," he notes. Perhaps Irving's most powerful educational tool is the example his own life provides.
