"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 bright computer screen on which a colourful dragon 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 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 special about it? Show me what it can do!"
"I think this is a great computer, Mum!" he said happily. "The hardware (硬件) is good. There’s so much memory and it has some wonderful software programs. This game, ’Dragon Player’, is my favourite, but I sometimes borrow games from Daniel and other friends. I don’t have to worry about any infected（感染） disks because I have a virus（病毒） detector (探测器) which can go over any disk and check it for viruses. Let me show you!" Tom began tapping. The screen changed in answer to his orders.
"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."

Two good friends, Sam and Jason, met with a car accident on their way home one snowy night. The next morning, Sam woke up blind. His legs were broken. The doctor, Mr Lee, was standing by his bed, looking at him worriedly. When he saw Sam awake, he asked, “How are you feeling, Sam?” Sam smiled and said, “Not bad, Doctor. Thank you very much for doing the special operation(手术).” Mr Lee was moved by Sam. When he was leaving, Sam said, “Please don’t tell Jason about it.” “Well…Well…OK,” Mr Lee replied.

Months later when Jason’s wounds healed(愈合), Sam was still very sick. He couldn’t see or walk. He could do nothing but stay in his wheelchair all day long. At first, Jason stayed with him for a few days. But days later, Jason thought it boring to spend time with a disabled man like Sam. So he went to see Sam less and less. He made new friends. From then on, he didn’t go to visit Sam any more. Sam didn’t have any family or friends except Jason. He felt very sad.

Things went from bad to worse. Sam died a year later. When Jason came, Mr Lee gave him a letter from Sam. In the letter Sam said, “Dear Jason, I am disabled. But I want you to be a healthy man. So I gave my eyes to you so that you can enjoy life as a healthy man. Now you have new friends. I’m glad to see that you are as healthy and happy as usual. I’m glad you live a happy life. You are always my best friend... Sam”. When he finished reading the letter, Mr Lee said, “I have promised that I will keep this a secret until Sam is gone. Now you know it.”
