“Tom? Are you in bed yet?” called Mrs. White. There was no answer. Mrs. White put down her book and went to her 14-year-old son’s room. Tom was sitting in front of a right computer screen (屏幕) on which a colorful dragon (龙) jumped and shouted.

　　“Oh, Tom! You’re still playing on that computer. You must stop now, it’s half past eleven. If you don’t go to bed soon, you’ll be very tired tomorrow.” said Mrs. White.

　　“But I’ve nearly beaten the dragon.” said Tom. Mrs. White could see the excitement (激动) on her son’s face. She sat down beside him.

　　“You are always playing on that computer. You spend more time with this machine than with your family.” she said with a smile. “What’s so special (特别的) about it? Show me what it can do!”

　　Tom was very excited. “I think this is a great computer, Mum!” he said happily. “The hardware (硬件) is good. There’s so much memory (内存) and it has some wonderful software programmes. This game, Dragons player, is my favourite, but I sometimes borrow games from Danny and other friends. I don’t have to worry about any infected (被感染的) disks (磁盘) because I have a virus (病毒) detector (监测器) which can go over any disk and check it for viruses. Let me show you!” Tom began tapping (敲打) keys on the keyboard (键盘). The screen changed in answer to his orders (命令).

　　“Oh, Tom.” laughed Mrs. White. “I’m sure it’s a wonderful computer, but I’m afraid I don’t know what you’re talking about.”
