     It's Saturday morning and Tony's sitting at the kitchen table, staring(凝视)into space and playing with

a piece of bread. He's not even hungry. Is he ill? No,  but he does have a problem. He has nothing to do

and there's a simple reason: the Internet is down and Tony has nothing to do.

     When he woke up this morning,  Tony was  feeling great.  He jumped  out of bed full of plans for the

weekend ahead. It would be a weekend like any other-a great weekend. But  that was before he turned

on his computer and was unable to go online. No Internet changed everything.

     Just as Tony is wondering how he can possibly have a normal(平常的)weekend without the Internet,

his mum walks into the kitchen. "Is everything OK?" she  asks. "No, mum, everything is definitely(的确)

not OK," her sad son replies. "I can't go online  and  I  have homework to finish." His mum laughs, "The

word program is still working, so what's the problem?"

     What's the problem? Tony can't believe his  own  mother  is  unable  to  see how serious the problem

really is. To start with, he still needs to do research for his homework. He knows his mum will tell him to

go to the library but he hates the library.  It's  so  dark  and  uncomfortable. And forget homework-what

about the rest of his weekend! Every weekend,  he goes  online to email friends. Then he reads the news

to catch up on what's happening in the world. He plays a few online games and finishes the weekend off

with an online chess game  with  his  cousin  Helen. The  wonderful  weekend-online!  Now it's Saturday

morning and he's not going to have access to(进入)the Internet for two whole days. He needs help.
