Another researcher, Robert Kraut, said he's worried about the “opportunity costs” of so much online time for youths.He found that teens who used computers, even just a few hours a week, showed increased signs of loneliness and social isolation.“Chatting online may be better than watching television, but it's worse than hanging out with real friends，” he said.

　　Today's teens, however, don't see anything strange in the fact that the computer takes up a central place in their social lives.“School is busy and full of pressure.There's almost no time to just hang out，” said Parker Rice, 17.“Talking online is just to catch up time.”

　　Teens say they feel good about what they say online or taking the time to think about a reply.Some teens admit that asking someone for a date, or breaking up, can be easier in message form, though they don't want to do so.But they insist there's no harm.

　　31．The researchers argue that ________.

　　A．teens may develop a different sense of values

　　B．nothing is wrong with teens' chatting online

　　C．teens can manage their social connections

　　D．spending hours online does much good to teens

　　32．Teens think that talking online can help them ________.

　　A．use computers properly

　　B．improve their school work

　　C．develop an interest in social skills
