Spending just a few hours a week online may make people feel more sociallyisolated(孤立的),
lonely anddownhearted(沮丧的), according to a two-year study of nearly 100 families with the
Internet.
"We were surprised to find that social technology has such bad effects on social communications,"
the lead author, Dr. Robert Kraut of Carnegie Mellon University in Pittsburgh, Pennsylvania, said in a
statement to the news. The findings suggest that "Rather than encourage students to use the Internet
alone for research, teachers might give pupils online group homework to complete with classmates.
Local groups might build websites that allow neighbors to discusslocal affairs(地方事务)."
"Before the technology develops and can be really morebeneficial, people shouldcontrol(控制)
their wishes to use much of the Internet," Dr. Kraut and other experts advise. In order to control their
children and encourage family activities, parents might think of putting the computer in the living room
rather than in a child's room, they suggest.
Dr. Kraut also suggests that when surfing on the net, especially when chatting with strangers on the
net, children should not use their real names, and that they should not tell the addresses, telephone
numbers to the strangers.
