    Tu Youyou, an 84-year-old scientist, became the first female (女性) Chinese to win a Nobel Prize in science on Oct,5. She shared the 2015 Nobel Prize for medicine because of the new medicine for malaria(疟疾). Tu started the research in the 1970s that made her find artemisinin(青蒿素), a kind of medicine that has saved many people's lives. It comes from Chinese traditional medicine and now is a good way to treat malaria.

    When the news came that Tu was given the prize, there were cheers as well as questions. Some said that her achievement(成就) was the result of lots of Chinese scientists working together. So it is unfair to give the prize only to Tu.

    However, Tu was awarded for “three firsts”. She was the first to bring artemisinin to her team, the first to extract(提取) artemisinin that can stop malaria, and the first to finish the experiment.

    Giving prizes to scientists with great ideas is the best way to keep national innovation(创新).

    Mary is an American girl. She is now in Beijing with her parents. She doesn‘t know Chinese, but she is trying to study and speak it .She often tries to speak Chinese to her Chinese friends. Sometimes they don't understand (理解 )her, because she can't speak Chinese well.

    It's Saturday morning. Mary goes out. She is on her way to the park. She is going there to see a flower show But she doesn't know how to get there. She asks a Chinese boy. The boy can't understand her. Then she takes out a pen and some paper. She draws some flowers on it, gives the picture to the boy and says something about it. The boy smiles and then shows ( 指 ) Mary the way to the park.

    Winnie the Pooh is about 100 years old. It is my favourite, and I'm sure it's also yours. Do you know how it came to our life?

    Winnipeg is a place in Canada. Many years ago, Harry, a soldier, went to Europe from here. When he stopped at train station, he saw a man selling a little black bear. Harry bought it and named it Winnipeg. The name became Winnie in short later.

    Harry went to a lot of places. When he got to London, he left Winnie in the London Zoo. He thought they could look after Winnie.

    Near the zoo, there was a boy named Robin. He loved to visit the London Zoo with his dad. Winnie was his favourite animal. Robin's father was a writer. He wrote the bear in one of his poems for the first time. Later he wrote stories about Winnie and Robin. Slowly, the father wrote more characters(角色) like Piglet, Rabbit, Roo and Tigger and so on in his stories.

    Hello, everyone! I'm Mike. I live in Beijing with my parents. I'm in Class Two, Grade Seven at Beijing International School. I'm looking forward to the busy weekend. All the students in our class are going to Tian'anmen Square to watch the flag­raising ceremony(升旗仪式) on Saturday morning.

    We're going to gather(集合) at five o'clock at the school gate. It takes us about twenty minutes to get there by subway. After watching the ceremony, we are going to visit the Railway Museum. I hope the weather will be fine! In the afternoon we are going to have a basketball match in the gym. In the evening we're going to see a movie. I don't think we're going home early on Saturday evening.

    On Sunday morning I'm going to Beihai Park with my friends. We're going to take a walk in the park and collect litter there. It must be very interesting.

    The back door of the ambulance(救护车) was suddenly shut and the driver ran to the front, jumped into his seat, and started the engine. Inside were the1 parents, Mr. and Mrs. Green, the mother holding their baby daughter Ally. The little girl had 2 food stuck in her throat and could hardly breathe.

    The driver, Mr. White, 3 his siren (报警器) and flashing light, and started speeding towards the nearest hospital, fighting against4. The cars ahead of him pulled out of the way as he drove through the 5from the back of the 6 the parents were shouting at him to    7 , since Ally had almost stopped breathing. In front of him he saw some traffic lights, with the red "STOP" light shining. Mr. White knew that he had no time to 8 , so he drove straight past the traffic lights, looking to his left and right as he did so.

    Coming towards him from his right was a taxi. The driver had the windows 9, since the car was air-conditioned, and he was playing his radio. He did not10the ambulance. The lights were green, so he drove straight on into the path of the ambulance.

    Mr. White tried to stop his ambulance but it was too late. It hit the taxi. Everybody was shaken but no one was hurt. Mr. White looked to see how little Ally was. He was astonished to see relief instead of 11on the faces of the parents.

    "Look!" cried Mrs. Green. "She is 12again."

    "It must have been the crash." said her husband. "It 13 the food out of her throat." The baby's color was turning to14 , and she was crying in a loud but healthy 15.

    They were all joyful, and quite forgot about the accident, the taxi, and the lines of cars all around them.

    US teenagers Hannah Lucas, 15, and her brother Charie, 13, have created an app called not OK. People just need to pay $1.99(12.5 yuan) each month to use it.

    Imagine having a simple app(应用程序) that works like: When you need help, just open the app, touch the "notOK" button and a text message will be sent to five pre-selected(预先选定的)people, along with a location(位置)to show where you are. The message reads, Hey, I'm not OK. Please call me, text me, or come to find me."

    Hannah was inspired(启发) to create the app during a dark time in her life last year. She suffered from a disease that caused her to pass out at school. Other kids sometimes bullied (欺凌)her about this. She felt sad and wanted to find an app that would allow her to get help when she wasn't feeling OK.

    She asked her brother Charlie, whose nickname is "Tech Support", to find such an app. When they couldn't find they decided to create one themselves.

    They came up with some designs for the app first Charie took a programming class last summer and built a website for the app. Hannah also shared her idea in her summer business class. Some app developers showed interest and decided to help her.

    Hannah is happy that her app is helping others. "It makes everything I went through last year worth it," she said.
