At the age of nineteen, Xiliu married Gao Sheng, who had just lost his wife and had a son named Changfu. A year later Xiliu gave birth to a boy Changhu. Before long, Gao Sheng died of illness.

Seeing Changfu didn't often go to school, Xiliu sent him to work with the poor boys as punishment. Changfu could not stand and wanted to return to school. Xiliu refused, and Changfu, like a beggar (乞丐)， huddled(蜷缩) himself up with cold. Xiliu said to Changfu, "If you are ready to take a beating of 100 strokes, I'll take you back." Changfu decided that he would take the beating. Aware of Changfu's regrets for his mistakes, Xiliu did not beat him and asked him to continue his studies.

      Changhu was a slow-minded child, so Xiliu asked him to quit school and work in the fields.

      But Changhu was so lazy that he often ran away from work. Xiliu then asked him to do business, but he used up all his money in gambling(赌博)． At last, Xiliu sent him to Luoyang to sell goods, where he was put into prison for using fake (假的) silver. In prison he suffered a lot. Xiliu told Changfu, "I gave the fake silver to your brother on purpose, intending to make him suffer. Now you go and get him out." Back home, Changhu knelt before his mother and finally gave up bad and returned to good.

    Mark and his brother Jason both were looking at the shining new computer enviously, Jason was determined not to go against their father's wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.

    "Dad will be really mad if he finds out you've been playing with his new computer." Jason said. "He told us not to touch it."

    "He won't find out, "Mark said." I'll just have a quick look and shut it down."

    Mark had been scolded before for touching his father's equipment. But his curiosity was difficult to control and this new computer really puzzled him.

    It was a strange—looking machine--one his dad had brought home from the laboratory where he worked. "It's an experimental model, "his father had explained," so don't touch it under any circumstances." But his father's warning only made Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the centre of the screen: "SPACE TRANSPORTER."

   "Yes!" Mark cried excitedly, "It's a computer game. I knew it! Dad's only been pretending to work. He's really been playing games instead. ''A new message appeared on the screen：

    "ENTER NAMES

    VOYAGER 1…

    VOYAGER 2… "

    Mark's fingers flew across the keyboard as he typed in both of their names.

    "INPUT ACCEPTED START TRANSPORT PROGRAM. AUTO RETRIEVE INITIATED(自动回收程序已启动). "

    The screen turned even brighter and a noise suddenly rose in volume.

    "I think we'd better shut it off, Mark, "Jason yelled, reaching for the power switch. He was really frightened.

    But his hand never reached the switch. A single bean, of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒), until the)themselves seemed to be glowing. Then it died down Just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.

    "TRANSPORT SUCCESSFUL. DESTINATION：MARS. RETRIEVE DATE：2025."

    He was 11 years old and went fishing every chance he got at his family's small house on an island in the middle of a New Hampshire lake.

    On the day before the bass(鲈鱼)season opened, he and his father were fishing early in the evening, catching sunfish and bass with worms. Before long, when his pole doubled over, he knew something huge was on the other end. His father watched with admiration as the boy skillfully worked the fish alongside the bank and he very successfully lifted the tired fish from the water. It was the largest one he had ever seen, but it was a bass.

    The boy and his father looked at the handsome fish, the fish jumped up and down in the moonlight. The father looked at his watch. It was 10 P.M.—two hours before the season opened. He looked at the fish, then at the boy. "You will have to put it back, my son," he said. "I have never seen such a big fish before." cried the boy. "There will be other fish," said his father. "The boy looked around the lake. No other fishermen or boats were anywhere around in the moonlight. He looked again at his father. Even though no one had seen them, nor could anyone ever know what time he caught the fish, the boy could tell by his father's voice that the decision was not be changed. He slowly worked the hook out of the lip of the huge bass and lowered it into the black water.

    That was 34 years ago. And he has never again caught such a beautiful fish as the one he landed that night long ago. But he does see the fish again and again—every time he comes up against a question of ethics(伦理). For, as his father taught him, ethics are simple matters of right and wrong. It is only the practice of ethics that is difficult.

    We would if we were taught to put the fish back when we were young. For we would have learned the truth. The decision to do right lives fresh in our memory. It is a story we will proudly tell our friends and grandchildren.
