    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.

    “Tara, come here.” her mother calls from the living room. Tara goes to her mother and sees the school report card in her hands.

    Tara now has a new rule for friendship and it is that a friend that lends a helping hand is a true friend.

The event took place one snowy January morning Thomas Smith was walking his dog, Jack, in the park." As I was walking, I just saw Jack running onto the ice towards the ducks in the middle, and then he fell into the water and couldn't climb out, "said Smith. He realized he had no choice but to try and save his dog." someone else told me the lake was only one - meter deep, but it was at least twice that. I had to break my way through the 6- cm ice. Finally, I got Jack by the neck, and pulled him out. I don't think I have ever felt so cold by the time we got back to dry land. And when we got there, everyone was asking if Jack was okay—— no one was particularly worried, about me!"

    A neighbor, Julie Brown, saw it all happen."The dog went onto an icy lake. All of a sudden, it started to go under. There were crowds of people around, and they were all shouting and screaming. Before I knew it, the owner Smith was in the water forcing his way through the ice. I can't begin to imagine how cold it was. Everyone was very nervous, but he was as cool as a cucumber — he just crawled back out, put the dog on its lead, and went home."

    Many regard him as a hero, but Mr. Smith is quite laid- back about it."Most dog owners are the same as me.They would do what I did without a second thought. But in the future, I'm going to make sure he's on lead near any ice ponds,

    Pets are members of our family. Would you do the same for them?

    Thomas Alva Edison is one of the greatest inventors of all times. One of his most famous achievements is the electric light. He tried thousands of times to make a long lasting light bulb (灯泡). Although the light bulb is not his invention, he is the only one to have made such a successful light bulb. Many people remember him for the invention of the electric light. He held a lot of patents (专利权) worldwide. Many of them were approved (批准) in USA.

    We can find his inventions in many fields. In fact, many of the advanced inventions were based on his ideas. He invented a phonograph (留声机), a film picture camera, a ticket recorder and so on.

    Edison was not a good student at school. But he loved to do new experiments. When he was still a child, he built his first lab to perform his experiments.

    An amazing story of Edison's childhood is that he almost made his servant die. Edison used to think that birds ate insects and these insects might make them fly. So, he collected these insects and blended them to make juice. He then let his servant drink the juice. After drinking the juice, the girl lost her sense. But luckily, she was saved.

    Some children are flying kites near the river. They are very high and Peter can see them in the classroom. His mother's friend Mrs White came to see his mother this morning and brought a kite to him. She gave it to him after lunch. It looks like a bird. He wanted to fly it but his mother didn't let him do so.

    "It's time to go to school," said his mother, "or you will be late. You can fly it after school."

    The boy was sad, but he said goodbye to Mrs White and went to school. Now he's in the classroom but he's looking out of the window. He doesn't listen to Miss Black. She writes something on the blackboard and then turns to the class and finds this.

    "Name nine things with milk in them, Peter," she says.

    The boy doesn't hear her and still sits there. A boy behind him taps his back and he knows it. He stands up and Miss Black asks him the question again. He thinks for a while and then says, \ madam. Tea, coffee, cake and... er.. six cows."
