Today it is common to see people who walk about with colored wires hanging from their ears wherever they go. They move about in their personal bubbles, sometimes unaware of what’s happening around them. 1.           . Outside life is shut out. So are you one of “them”?

For me, walking around in my own personal bubble is perfect. 2.       What’s even better, wearing earphones seems to give a signal to people which says: “I’m not available for chatting at the moment!”

Suppose you’re at work and about to make an incredible breakthrough, but a colleague suddenly turns up. At this precise moment, the slightest disturbance would break your concentration.   3.                Once again, those wires hanging from your ears would be sure to give that “Go away!” signal.

4.          It’s probably part of the growing up stage when they just want to ignore their whole family. While their mothers give them lectures about why they should do their homework, they can just turn up the volume(声音) on their MP3 player, smile, and say “Yes, Mum.” Problem solved.

Pretty soon, not only will we have pretty colored wires hanging from our ears—but also our brains will be directly plugged into some new high-tech instrument. We’ll be in a virtual(虚拟) world, communicating with everyone else, or choosing not to, as we like. In this world, we will all be permanently plugged in. 5.        And they are changing our social habits along the way.

In the end, there is a thin line between using technology as a tool for making life better and being a slave to it! It’s so strange—suddenly, I don’t feel like wearing my earphones any more!

A.  Listening to music through earphones is the perfect way to ignore such interruptions.

F. Our instruments are changing quickly.

G. In the home situation, teenagers love these wires.
