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.

几天后，开面包铺的克瑞波先生来我家，怒气冲天地喊道：“那个海德是个骗子，瞧他给我的支票，全是假货。银行的人告诉我，他早把款兑光了。”在一旁的杰妮大婶得意地点着头，那神态分明是说：“看，我不是提醒过你们了吗？你们不听嘛。”“我敢打赌，他也欠了你们家许多钱，是不是？”克瑞波不无希望地探问道。 
妈妈转过身向着我们，目光长久地停留在尼尔斯身上，然后走到炉子边，把支票投入炉火。 
“不！”他向克瑞波先生回答道，“不，他什么也不欠。” （选自《世界微型小说名家名作百年经典》有改动）
