阅读下列短文,从每题所给的A、B、C和D项中,选出最佳选项。

A

“I sometimes get up at three or four in the morning and I surf the net.”

“I often check my e-mail forty times a day.”

“I often spend more than three hours during one time on the net.”

For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight.

Studies show that about 6 to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them.They spend more time in cyberspace than in the real world of friends and family.
