Just how comfortable is your sofa? Would you be prepared to let a stranger crash out there for the night? And, on the basis of a bit of email correspondence and seeing a photo of the sofa belonging to 'A. N. Unknown', would you travel halfway across the world to do the same? It might sound crazy, but this is exactly what millions of people have done whilst participating in an activity known as couch surfing.
Couch surfing is traveling on a budget, using a broad network of contacts in order to get overnight accommodation for free, or at as little cost as possible. Participants join dedicated(專業(yè)的) websites, providing as much information about themselves as possible in order to make others feel comfortable hosting them, or using them as a host.
Various safety features are generally available in such online networks, like verification of names and addresses, personal references, and 'vouching for' a particular member as a reliable host or guest.
As well as the financial advantages of couch surfing, participants also claim that the practice gives them a more unique, authentic travel experience, allowing them to experience culture and cuisine through the locals, rather than from the confines of sanitized tourist accommodation. We open our minds and lives and welcome the knowledge that becomes available through cultural exchange.” Said Casey Fenton, founder of Couch Surfing. Com. “CouchSurfing wants to change not only the way we travel, but how we relate to the world.”

Probably you have seen photos of the Grand Canyon（峽谷）, the great valley in the desert country of Arizona. But you must go there yourself to feel its true size and beauty. The Grand Canyon is one of the greatest natural wonders of the world
The Colorado River formed the Grand Canyon over millions of years. Slowly, the river cut down through hard rock. At the same time, the land was rising. Today the canyon is 1.5 kilometers and 445 kilometers long. The oldest rocks at the bottom of the canyon are more than 1 billion years old. The width varies from about 200 meters to 29 kilometers across. The rim or top of the canyon is about 2,300 meters above sea level on the South Rim, and about 3,000 meters on the other side. As a result, there are different kinds of plants and animals on opposite sides of the canyon. The South Rim is dry desert country. The North Rim has tall forests.
The canyon looks different at different times of day, and in different seasons and weather. At sunrise and sunset the red, gold, brown and orange colors of the rocks are especially clear and bright. In winter, the canyon is partly covered with snow.
The view from the South Rim of the Grand Canyon is the best. Most visitors come here and stay in campgrounds or hotels. Every point along the canyon’s edge offers a different view.
The North rim of the Canyon is quieter. It takes all day to drive there from the South Rim because there is only one bridge across the Colorado River. On the way, you go through Navado Indian lands, and a colorful pink desert called “The Painted Desert”.
