Sam and Computer Games

　　“Sam? Are you in bed yet?”called Mrs. Blake. There was no answer. Mrs. Blake put down her book and went to her 13-year-old son's room. Sam was sitting in front of a bright computer screen on which a colorful dragon (龙) jumped and shouted.

　　“Oh, Sam! You're still playing on that computer. You must stop now; it's half past 11. If you don't go to bed soon, you'll be very tired tomorrow,”said Mrs. Blake.

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

　　“You're 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 about it? Show me what it can do!”

　　Sam 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, Dragonsplayer, 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 because I have a virus (病毒) detector (指示器) which can go over any disk and check it for viruses. Let me show you!”Sam began tapping keys on the keyboard. The screen changed in answer to his orders.

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