Guide to Hiking on the Appalachian Trail How do I "Leave No Trace on the Appalachian Trail?" At about 2,189 miles, the Appalachian Trail is the longest single unit of the National Park System. With the number of people visiting this place increasing each year, the chances are great that any of us may damage the natural environment along the Trail and affect the experience for others. So please do your part by following these hiking and camping practices, and encourage others to learn about and adopt these techniques. 1 Plan ahead and prepare. Evaluate the risks associated with your outing, identify campsites and destinations in advance, and use maps and guides. Prepare for extreme weather, dangers, and emergencies - especially the cold - to avoid impacts from searches, rescues, and campfires. Learn when areas are most crowded and try to avoid those times. 2 Dispose of waste properly. Pack out all trash and food waste, including that left behind by others. Don't bury trash or food, and don't try to burn packaging materials in campfires. Use the privy for human waste only. Do not add trash. If there is no privy, dispose of human waste by burying it in a hole, a hole at least 200 feet (80 steps) from campsites, water sources and shelters, and well away from trails. 3 Leave what you find. Leave plants, cultural artifacts and other natural objects where you found them for others to enjoy. Do not damage live trees or plants; green wood burns poorly. Collect only firewood that is dead, down, and no larger than your wrist. Leave dead standing trees and dead limbs on standing trees for the wildlife. 4 Minimize campfire impacts. Use stoves for cooking - if you need a fire, build one only where it's legal and in an existing fire ring. Keep fires small. Never leave your campfire unattended, and drown it when you leave. Do not try to burn trash, including plastic, glass, cans, tea bags, food, or anything with food on it. These items do not burn thoroughly. They create harmful fumes , and attract wildlife like...

Thank you for trusting me. I enjoy exchanging my ideas with yours The first thing I want to tell you is that if the boys are calling you names it is their fault, not yours. Boys, at your age, are different from girls. They are trying to prove that they are manly and then often do this by picking on someone who can't really fight back. This is, of course, wrong but it happens. In general, the boys know they are bigger and stronger than you are, so they can make fun of you and make you cry and then laugh about it. If you let them see that they are hurting you, they will only do it more. It isn't that they want to hurt you; they simply want to make themselves feel superior . It's stupid, but it is common. In English we say " sticks and stones may break my bones but names will never hurt me." Canadian children learn this from their mothers because the same thing that is happening to you in China also happens here. The best ways of getting the boys to stop calling your names is to simply ignore them, knowing that the names can't hurt you and that the boys are being stupid. If you can laugh at them they will get tired of trying to make you cry and they'll give up. It won't be easy, but, trust me, it will work. There is also something else working in your favor and that is that you are growing up and the boys are beginning to notice you as a young woman. I suspect some of them actually like you and are making fun of you just to get your attention. Again, it's stupid but it happens. In reality, you can control this situation by not letting them see you getting hurt. Laugh at them, tell them they're acting like children and they should grow up and then walk away with your head held high. One more thing, Nancy. It is very important that you stop hurting yourself. If someone else hurts you, it is bad enough but you should't make it worse by then hurting yourself. Even sticking a pen into your finger can cause an infection and give you a lot of trouble and besides, it hurts. The next time you are disturbed by a group of... Nancy hurt herself because she _ . A) couldn't prevent the boys taking interest in her B) felt it her own fault to be called names by boys C) found herself more stupid than the boys D) wanted the boys to see her hurt by herself

*Question*
Eddie McKay, a once-forgotten pilot, is a subject of great interest to a group of history students in Canada. It all started when Graham Broad, a professor at the University of Western Ontario, found McKay's name in a footnote in a book about university history. McKay was included in a list of university alumni who had served during the First World War, but his name was unfamiliar to Broad, a specialist in military history. Out of curiosity, Broad spent hours at the local archives in a fruitless search for information on McKay. Tired and discouraged, he finally gave up. On his way out, Broad's glance happened to fall on an exhibiting case showing some old newspapers. His eye was drawn to an old picture of a young man in a rugby uniform. As he read the words beside the picture, he experienced a thrilling realization. "After looking for him all day, there he was, staring up at me out of the exhibiting case," said Broad. Excited by the find, Broad asked his students to continue his search. They combed old newspapers and other materials for clues. Gradually, a picture came into view. Captain Alfred Edwin McKay joined the British Royal Flying Corps in 1916. He downed ten enemy planes, outlived his entire squadron as a WWI flyer, spent some time as a flying instructor in England, then returned to the front, where he was eventually shot down over Belgium and killed in December 1917. But there's more to his story. "For a brief time in 1916 he was probably the most famous pilot in the world," says Broad. "He was credited with downing Oswald Boelcke, the most famous German pilot at the time." Yet, in a letter home, McKay refused to take credit, saying that Boelcke had actually crashed into another German plane. McKay's war records were destroyed during a World War II air bombing on London -- an explanation for why he was all but forgotten. But now, thanks to the efforts of Broad and his students, a marker in McKay's memory was placed on the university grounds in November 2007. "I found my eyes filling with tears... What is the text mainly about? A) The research into war history. B) The finding of a forgotten hero. C) The pilots of the two world wars. D) The importance of military studies.
