     Just how comfortable is your sofa? Would you be prepared to let a stranger crash

(躺下睡觉) out there for the night? Just on the basis of a short email correspondence

(通信) and seeing a photo of the sofa,would you travel halfway across the world to do

the same? It might sound crazy,but this is exactly what millions of people are doing-it's

known as couch(沙发) 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 join

dedicated(专业的) 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 available in such online networks,like verification (确认)

of names and addresses,personal references and vouching (担保) 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 get to know culture

and cuisine through the locals rather than through tour agents."Couch surfing is not just about

finding free accommodation.We open our minds and lives and welcome the knowledge that

becomes available through cultural exchange," said Casey Fenton,founder of

CouchSurfing.com, "CouchSurfing wants to change not only the way we travel,but how we

relate to the world."
