Article: The coast of the State of Maine is one of the most irregular in the world. A straight line running from the southernmost coastal city to the northernmost coastal city would measure about 225 miles. If you followed the coastline between these points, you would travel more than ten times as far. This irregularity is the result of what is called a drowned coastline. The term comes from the glacial activity of the Ice Age. At that time, the whole area that is now Maine was part of a mountain range that towered above the sea. As the glacier descended, however, it applied enormous force on those mountains, and they sank into the sea. As the mountains sank, ocean water charged over the lowest parts of the remaining land. And the highest parts of the former mountain range, nearest the shore, remained as islands. Marine fossils found here are 225 feet above sea level indicating the level of the shoreline prior to the glacier. The 2,500-mile-long rocky and jagged coastline of Maine keeps watch over nearly 2,000 islands. Many of these islands are tiny and uninhabited, but many are home to blooming communities. Mt. Desert Island is one of the largest, most beautiful of the Maine coast islands left behind by the glacier. Measuring 16 miles by 12 miles, Mt. Desert was very nearly formed as two distinct islands. It is split almost in half by Somes Sound, a very deep and very narrow stretch of water seven miles long. For years, Mt. Desert Island, particularly its major settlement, Bar Harbor, has afforded summer homes for the wealthy. Recently, though, Bar Harbor has become a new arts community as well. But the best part of the island is the unspoiled forest land known as Acadia National Park. Since the island sits on the border between two different geographical zones, the park supports the plants and animals of both zones. It also lies in a major bird migration lane and is a resting spot for many birds. The establishment of Acadia National park in 1916 means that this natural monument will be preserved and that it will be available to all people, not just the wealthy. Visitors to Acadia may receive nature instruction from the park naturalists as well as enjoy camping, hiking, cycling, and boating. Or they may choose to spend time at the museum learning about the Stone Age inhabitants of the island.

When we.arrived at the sate we could see the courtyard, vast and full of boys and girls.I hesitated and clung to his hand, but he gently pushed me from him."Be a man, "he said."today you truly begin your life.You will find me waiting for you when it's time to leave."

Rivalries could bring about pain and hatred or give rise to fighting.And while the lady would sometimes smile, she would often yell and scold.Even more frequently she would resort to physical punishment.

Article: Nowadays more and more young athletes are taking part in the risky activities called "extreme sports" or "X-sports". In the past young athletes would play baseball. Today, they want risk and excitement -- the closer to the edge, the better. They snowboard over cliff and hike deep mountains. Extreme sports started as an alternative to more expensive sports such as golf. A city kid who couldn't afford expensive sports equipment could get a skateboard and have fun. But now it has become a whole new area of sports, with specialized equipment and high levels of skill. There is even an Olympics for extreme sports, called the winter x-game, which includes snow mountain hiking and ice climbing. What makes extreme sports so popular? Maybe it's because people love the risk. City people want to be outdoors on the weekends and do something challenging. The new equipment is so much better that people can take more risks without getting hurt. Sure there's a risk. Once you go mountain hiking or snowboarding, it's impossible to go back to have riding or skiing. It's just too boring. Now even the older crowd is starting to join in. Every weekend, groups of friends in their early 30s get together. On weekdays they work as computer programmers in the same office. On weekends they hike mountains together. Extreme sports are certainly not for everyone. Most people still prefer to play basketball or watch sports on TV. But it has been a fact that extreme sports are gaining popularity.
