     [1] 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.But I became invisible,absent

from the conversation.

     [2] The telephone used to connect you to the absent.Now it makes people sitting next to you  feel

absent.Recently I was in a car with three friends.The driver told us to be quiet because he could not hear

the person on the other end of his cell phone.There we were,four friends going down the highway,unable

to talk to one another because of a tool designed to make  communication easier.

     [3] Why is it that the more connected we get,____________?Every advance in  communications

technology is a hurt to the closeness of human interaction (互动). 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.

     [4] More_and_more,I_find_myself hiding_behind_email 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.

     [5] 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 home.
