Every advance in communications technology is a tragedy to the closeness of human interaction.With e－mail 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 mum 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 any more.Directory assistance is almost always fully automated.I am not against modern technology.I own a cellphone, an ATM card, a voice mail system, and an e－mail 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.So I've put myself on technology restriction: no instant messaging with people who live near me，no cellphoning in the presence of friends, no letting the voice mail pick up when I'm at home.20．Which of the following would be the best title of the passage?A．The advance of communications technologyB．The consequences of modern technologyC．The story of communications revolutionD．The automation of modern communications21．The sentence “Now it makes people sitting next to you feel absent.”means that ________．A．the people sitting beside you have to go away to receive a phone call B．you can hardly get in touch with the people sitting beside youC．modern technology makes it hard for people to have a face－to－face talk D．people can now go to work without going to the office22．The writer feels that the use of modern communications is ________．A．encouraging B．disappointingC．satisfying D．embarrassing23．The passage implies that ________．A．modern technology is bridging the peopleB．modern technology is separating the peopleC．modern technology is developing too fastD．modern technology is interrupting our communications课时作业(十四)Ⅰ.1.D 2.C 3.A 4.B 5.A 6.C7．B 考查倍数表达法。
