(2008年惠州三模)Nowadays,millions　 1　 lonely singles are now going online instead.　 2　 World Wide Web is quickly becoming the world^,s most popular matchmaker(媒人).

Singles are flocking(涌向)to the Internet　 3　 because their busy lifestyles leave them little time to look for a significant other.Using dating sites(约会网址)is quick and convenient.Many singles say the regular dating scene　 4　 (just lead)them from one bad experience to　 5　 and are ready to try something else.Dating sites also make　 6　 easy to avoid someone　 7　 you are not interested in.In the real world,?　 8　 ,ignoring someone you don^,t like can be difficult.

Despite all the advantages,online dating also presents its own set of problems.People aren^,t always those who they declare to be in their online　 9　 (describe).Safety is another concern.You are just　 10　 (like)to find a criminal online as you are Mr.or Miss Right.　

At one point along an open highway,I came to a crossroads with a traffic light.I was alone on the road by now,but　 1　 I drove up to the light,it turned red,and I braked to a halt.I looked left,right,and behind me.Nothing.　 2　 a car,no suggestion of headlights,but there I sat,　 3　 (wait)the light to change,the only human being for at least a mile in any direction.

I started wondering　 4　 I refused to run the light.I was not afraid of　 5　 (catch)by the police,because there was obviously no cop anywhere around and　 6　 certainly would have been no danger in going　 7　 it.

Much later that night,the　 8　 question of why I^,d stopped for that light came back to me.I think I stopped because it^,s part of a contract(合同)we all have with each other.It?s not only the law,but it^,s an agreement we have,and we trust each other to honor　 9　 :We don?t go through red lights.Like most of us,I^,m more ready to be stopped from doing something bad by the social agreement that disapproves of it　 10　 by any law against it.
