阅读理解。

     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

"An 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 travelling 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, also called couch surfers, join

dedicated 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 (核实) of names and addresses,, personal references, and "vouching

(担保) for" a particular member; 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 (真正的) 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. "Couch Surfing wants to change not only the way we travel, but how we relate to

the work."
