     Two thirds of the single people looking for love in Britain turned to the Internet last year, according to

figures made in public yesterday. Special sites offer introductions to people such as smokers, Roman

Catholics, tall people, beautiful people, frequent flyers and vegetarians. Technology has brought about a

great change in the dating (约会) games.

     A survey by Parsnip, a Britain branch of Europe's largest dating service with more than 1.5 million

members, says that 65 percent of the 5.4 million Britons looking for a relationship used online dating

services last year.

     A spokeswoman for Relate, the relationship advisor, confirmed that a figure of two thirds feel it all

right. "Doing it online allows people quite a lot of privacy, (隐私) because they can do a bit of quiet

research and look around from the comfort of their own home. You don't have to meet a matchmaker

(媒人) or go to an actual dating agency office, which takes a lot of courage." She said.

     There are more than 100 independent online dating agencies in Britain. Parsnip says that 50 percent

of single people believe they will meet a suitable partner through the Internet, from 35 percent six months

ago.

     Mary Balfour, the founder, says that the Internet has changed the dating industry completely. "It's like

a return to old-fashioned love letters," she said." You don't base your first judgment on how someone

looks or what his or her figure is like. You e-mail or talk before you actually see each other. Everybody

you know who is single these days has at least had a good look at a dating site, introduction agency or

personal ads. They have to, because all the old matchmaking institutions have gone. People work harder,

settle down later and live more isolated lives. They are much more likely to end the day with DVD and a

glass of beer than by going to a meeting place.
