Article: You may not know a lot of people when you start high school. Even if you know some new students, you still feel nervous that you don't know any upperclassmen and teachers. How are you going to make friends among this sea of unknown faces? Most high schools welcome new students before school actually starts. These are helpful not only because you learn your way around the buildings and get to meet some of your teachers, but also because you get to meet new students. That way, when you show up on your first day of school, you may already recognize a few familiar faces. When you talk to people, you'll probably find that a lot of them are feeling just like you. They're all new to the school and don't know what to expect. Talking about a common concern with your classmates can help you develop friendships. The work in high school is something freshmen are probably worried about. The work in high school builds on what you learned in middle school, giving you a more advanced knowledge of many subjects. So you may find you have more work to do or that it's a bit more challenging . If you ever find your work too difficult, teachers can give you extra help. High school also has more activities after class than middle school, such as clubs, music and theater groups and sports teams. This is a good time to explore your interests and try new things. Middle school taught you the basics of academics, time management, and social skills while providing you with a little extra support and guidance. High school gives you the chance to learn how to be more independent and responsible .

Article: $? While the 2008 Olympics were the first to be broadcast entirely in HD, the 2012 Olympics are the first to broadcast in HD as well as 3D. Sean Taylor, a spokesperson for Panasonic - provider of some of the technologies - said it effectively, "Each Games, from a technology perspective, tries to have a first. London will be the first HD and 3D Games." The games were first televised in Berlin in 1936 and played on big screens about the city. Then came the first games to enter households (strictly in London that is) in 1948, followed by the first internationally televised games during the 1960 Olympics in Rome. And ever since, that feeling of physically standing in the crowd and watching these mighty contestants has only gotten clearer, more defined. Now, they more literally than ever actually compete in your living room. SS A _ is presented as the London games celebrate both the Industrial Revolution (a.k.a. the birth of pollution) and a spirit of committed environmentalism; London will be the first to actively measure its own carbon footprint during these games, designing a stadium and accommodations that cut-back on negative emissions when at all possible. They are also shooting for a world record via the "Javelin," designed specifically to keep as many exhaust pipes at bay as humanly possible.

Article: The World's Largest Insect .This giant insect can be used as a toy. A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around. The child is African, and the toy is the African Goliath beetle, the largest insect in the world. The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel. African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless.
