The  iPod  Generation

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. They walk around in their own spaces, with their personal “digital（数码的） noise reduction systems”   1. 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 a breakthrough, but a colleague suddenly turns up. At this exact moment, the slightest disturbance would interrupt your work.    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 “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(虚拟的) world, communicating with everyone else, or choosing not to, as we like.   5. And they are changing our social habits along the way.

A. Outside life is shut out.

B. Our high-tech tools are changing quickly.

C. I also have wires hanging from my ears.

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

E. I don't have to deal with the noise from the environment.

F. After all, I am listening to my favourite music and would rather not be disturbed.

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