题型：阅读理解

A funny thing happened on the way to the communications revolutions: we stopped talking to one another.

I was walking in the park with a friend recently，and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and…I became invisible, absent from the conversation.

The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communications technology is a tragedy to the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another, With voice mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine.

As almost every contact we can imagine between human beings gets automated, the alienation index goes up. You can't even call a person to get the phone number of another person my more. Directory assistance is almost always fully automated.

I am not against modern technology. I own a cell phone, an ATM card a voice mail system, and an email account. Giving them up isn't wise…they're a great help to use. It's some of their possible consequences that make me feel uneasy.

More and more .I find myself hiding behind e-mail to do a job meant for conversation. Or being relieved that voice mail picked up because I didn't really have time to talk, The industry devoted to helping me keep in touch is making me lonelier…or at least facilitating my antisocial instincts．

So I've put myself on technology restriction: no instant messaging. with people who live near me，no cell phoning in the presence of friends, no letting the voice mail pick up when I'm at home.

甲乙两人是某大学学生，甲经常通过校园网出售一些二手东西。一日，两人通过MSN洽谈二手掌上电脑的买卖事宜。甲称：“我有掌上电脑一台，配置为……，九成新，附有数码照片可供参考，2800元要不要？”乙回话称：“东西不错，2400元的话可以接受。”甲回复：“可以，6月7日到我这儿来取。”乙回话：“同意。”于是两人结束了聊天。6月7日乙到甲处取电脑，发现甲的电脑运行速度比较慢，比约定的标准差很多，便拒绝接受，甲遂降低价格，拟2000元出手，乙同意。由于乙想通过自己做兼职挣钱来付款，于是甲乙又约定分5期付款，每期400元，于每月月底支付，乙当即支付了400元，并取走电脑。临走时乙问甲电脑使用前是否需要杀毒或者重装系统，甲说自己刚买不久，从未感染过病毒，于是乙放心地离开甲处。根据上述案情回答第91-93题：
