    China has its first Nobel Prize in Science. And the winner, 84-year-old Chinese scientist Tu Youyou, also became the first Chinese woman to win the Nobel Prize. She won the 2015 Nobel Prize in Physiology or Medicine with William C. Campbell, an Irish-born researcher, and Satoshi Omura of Japan. The three winners will share the prize of 8 million Swedish crowns ($920,000).

    Half of the Prize was given to William C. Campbell and Satoshi Omura for their new treatment against illness caused by roundworm parasites (寄生虫). Tu Youyou won the other half of the Prize for developing a medicine, Artemisinin(青蒿素), which can help people fight malaria(疟疾). More than 240 million people in Africa have benefited from the treatment, according to the WHO (World Health Organization), and more than 1.5 million lives have been saved since 2000, thanks to the medicine.

    Tu Youyou started her research in 1969 when she was chosen as the director of a government project to find anti-malaria medicines. She and her workmates studied ancient Chinese medicine books and many different traditional treatments. They did nearly 200 experiments before they finally succeeded in getting the material Qinghaosu, later known as Artemisinin, in the 1970s. This medicine became the standard treatment for malaria in the WHO's list of important medicines.

    Premier Li Keqiang congratulated Tu for winning the Prize. He said, "Tu's winning the prize shows China's progress in scientific and technological field, and marks a great contribution of Traditional Chinese Medicine (TCM) to human health."

    Although it's a late honor for Tu and the world's recognition of Traditional Chinese Medicine, Tu's winning the first Nobel Prize in Physiology or Medicine makes Chinese scientists encouraged and confident to achieve more success in the future.

Deisha walked up and down as she waited backstage. This would be her most important piano performance yet. At ten years old, she was the youngest performer in the recital (音乐演奏会). She had practiced playing her song more than 30 times that week. When she closed her eyes at night, the music played over and over again in her head.

    Now that the day had arrived, Deisha was not sure she was ready. She smoothed her hair and picked a piece of lint (绒毛) from the new dress that her mother had bought for her. She noticed that her hands were shaking. How could she play the notes of the song if her hands were shaking? She tried to concentrate on steadying (稳住) them, but they only shook more.

   Deisha's piano teacher, Ms Neal, walked up to speak to her. “I have something for you,” she said, putting a smooth black stone into Deisha's hand. “It's a special stone. There's no other one like it in the world. You've practiced so much, you don't need anything else.”

   The stage lights reflected off the rock. “Thank you,” Deisha said.

   When Deisha's name was called, she rubbed the stone, stepped onto the stage, and played better than ever. After her performance, she noticed that Ms Neal had a whole bag of black stones. “Why did you say this one was so special?” she asked.

   Her teacher responded, “Because, like your talent, it belongs only to you.”

    Mr. Knott [not] is a teacher. He teaches in a big school in London. Because he lives a long way from the school, he is usually quite tired（疲惫的） when he get home. At nine o'clock one evening when he is in bed, the telephone rings（铃响）, so he answers the phone, " Hello! Who's that?"

    "Watt [what]." a man says.

    "What's your name, please?" says Mr. Knott.

    "Watt's my name," the man answers.

    "Yes, I asked you that what is your name." Mr. Knott asks.

    "I told you. Watt's my name." says the man. "Are you Jack Smith?"

    "No, I'm Knott," says Mr. Knott.

    "But what's your name?" the man says.

    Mr. Knott and Mr. Watt put their telephone down and think, "What a foolish（愚蠢的）man!"

    There once lived a rich businessman who had a lazy son. The businessman wanted his son to realize the value of labor.

    One day, he told his son, "Today, I want you to earn something. If you fail, you won't have your meal tonight."

    The boy didn't want to find a job, so he asked his mother for help. She gave him a gold coin. In the evening, when the father asked his son what he had earned, the son showed him the gold coin. The father then asked him to throw it into the well (水井). The son did as he was told.

    The father guessed that the gold was from the boy's mother. The next day, he sent his wife to her parents' home and asked his son to earn something. Since no one helped him, the son had to go to the market to look for a job. A shopkeeper told him that he would pay him a coin if he carried heavy tools for him. The son accepted. As he returned home and gave the coin to his father, he was asked to throw it into the well. The boy cried, "Dad! My body is aching. I'm tired. How are you asking me to throw my hard-carned coin into a well?"

    The businessman smiled. He told his son that one feels pain only when the fruits of labor are wasted. The son realized the value of hard work. He promised not to be lazy any more.

    Mr. Brown was going away for a week. Before he left, he said to his son, "if anyone asks for me, you can tell him that your father has been out for doing something, and will be back in a week, then be sure to ask him to sit down for a cup of tea."

    "OK, Dad," said his son. But he was afraid his son couldn't remember this, he wrote these words down on a piece of paper and gave it to him. His son put it into his small pocket, took it out and looked at it every now and then.

    Four days passed, but no one came to see his father. The boy thought that there was no man to come and that the piece of paper was of no more use for him, so he burnt it that evening.

    The next afternoon, someone knocked at the door. The boy opened it. A man was standing at the door and said, "Where is your father?" The boy put his hand into his pocket at once and looked for the piece of paper. He could not find it. He suddenly remembered he had burnt it, so he shouted, "No more."

    The man was very surprised. He asked, "No more? I met your father last week. When did it happen?"

    "Burnt yesterday evening."
