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... Question: Before you hike on the Appalachian Trail, you are advised to _ . Options: A: keep everything that you find there B: bring some food for the wildlife there C: prepare for bad weather and emergencies D: avoid crowded periods and book a hotel in advance

Read the article and select the best answer. Article: News that Microsoft was making a $44.6 billion bid to buy Yahoo was greeted with heated discussion by many Internet users on Friday. Here are some responses: Mark Galeassi of Kansas City, Missouri This is the best move for both parties. Yahoo has the ideas and Microsoft has the money to finally market these ideas correctly. Microsoft and Yahoo are a perfect fit and the deal will be good for consumers. Scott G of New Jersey I was a Yahoo user for years along with Hotmail from Microsoft. Then Google came along: Google Earth, Google Toolbar and Gmail. Google is so innovative with everything they do. Yahoo and Microsoft... same old story... I don't think the merger will do anything for either company except improve the Yahoo shareholders' bank accounts. Michael Glosser of Estero, Florida Right now, Yahoo offers a lot of features and tools at no cost for all different levels of Internet users. Microsoft seeks nothing but profit. Undoubtedly, they'll do nothing other than find ways to start removing Yahoo's formerly non-priced features. Microsoft's greed will ruin the great thing that Yahoo currently is. Toni Suarez of Hacienda Heights, California Perhaps it would bring better high technology innovations to e-mail and help in researching and developing a better Internet! Antonio Simmons of Parkville, Maryland Microsoft purchasing Yahoo would be nothing more than an attempt from Microsoft to further impose upon the users their poor-quality software and obtain more wealth for the company. In my opinion, they will never be able to compete with Google because Yahoo and Microsoft's current search engines are too inferior to compete. Even if combined, they still lack. Question: Michael Grosser is afraid that _ . Options: A: the merger will cost Yahoo's free features B: the merger will lead to Microsoft's defeating Yahoo C: the increased competition will force Google out of the game D: Internet users will have to buy Microsoft's expensive software

Ques: Read the article and select the best answer. Article: Scientists warn today that the Atlantic bluefin tuna faces disappearance unless certain action is taken. They used electronic ways to track the movement of the powerful fish from the Gulf of Mexico to the Mediterranean, and report today in the journal Nature that meals of sushi and sandwiches with tuna worldwide are more dangerous than anyone has imagined. The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A good one can fetch as much as PS 52,000 in the Tokyo fish markets. "In my lifetime, we've brought this big fish to the doorstep of death in the western Atlantic Ocean," said Barbara Block of Stanford University in California. "The electronic way of tracks provides the best scientific information we've ever had to manage these tuna and we must, as an international community, start to act actively to make sure of the future of this fish. " Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore in search of deep ocean fish. Tuna--in the Mediterranean and Japan--have been under increasing pressure for years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since 1969.There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger, eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000 in the east, no one knew whether the limits worked. So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water temperatures. "There are two ways to save the Atlantic bluefin tuna--protect them in their production grounds and in their feeding grounds," Prof. Block said. "This will need immediate action in both the central Atlantic, to reduce the loss of the big... Question: The purpose of the passage is to _ . Options: A: tell people a new way has been found to save the bluefin tuna B: call for action to save the bluefin tuna C: warn people not to eat tuna sandwiches anymore D: help scientists to find a new way to save the bluefin tuna

Read the article and select the best answer. Article: Women teachers are holding back boy students by blaming them for typically male behavior, according to a new study. Women teachers are always saying that boys are "silly" in class. They refuse to "sit nicely like girls" and are more likely to be addicted to "schoolboy tricks".Women teachers may also keep low expectations of boys' academic achievement and encourage girls to work harder by letting them think they are cleverer than boys. The study suggests that under-performance among boys in most national exams could be linked to lower expectations of their women teachers. The researchers did their research mainly on women teachers, since nearly 90 percent of primary school teachers are female. According to the research, women teachers said they often found boys' play in the classroom or in the playground, such as playing with toy guns. The researcher also found that boys were often punished and urged to follow a more feminine style of play instead of being taught how to play responsibly with their favorite toys by their women teachers. Bonny Hartley, the study's lead author, said, "By seven or eight years old, children of both boys and girls believe that boys are less focused, less able, and less successful than girls -- and think that adults admit this idea. There are signs that these expectations have the potential to become self-fulfilling in influencing children's achievement. Boys are really held back by their women teachers." Question: What is the women teachers' attitude towards the boys? Options: A: They encourage boys to work harder at their lessons. B: They keep the same expectations of boys and girls. C: They are always thinking that boys are silly in class. D: They think boys are cleverer than girls in their studies.
