    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.

    Max is one of my good friends. I first met him two years ago when he knocked on my door (敲我的门)."Hello," he said warmly. "My name is Max, and I've just moved in next door, so I'm your new neighbor."

    Max is a handsome, well-dressed young man in his twenties. He is quite tall and thin with brown eyes and black hair. He likes wearing sports clothes. He works in a hospital and goes to work early every day.

    He has a great sense of humor (幽默感). I love to listen to his interesting stories. What's more, he is a very kind-hearted person, and is always ready to help people in need. He often does volunteer work (志愿者工作) in an old people' s home. Because of him, more and more young people in our neighborhood want to help there.

    He enjoys dangerous sports such as bungee jumping (蹦极跳). He is a great dancer, too. He goes to the dance club every Tuesday and Saturday.

    All in all, life is never boring when Max is around. Who wouldn't be happy to have him as a friend and neighbor?

    Mike teaches a very basic programming (编程) course to a group of students. They are all very interested in computers.

    One day, Mike told his students to write a short program on their computers. After writing it, they only needed to type "R", "U" and "N" and press "enter" to see the program run.

    Soon, a student sitting in the back of the classroom put up her hand. She said, "I did what you said, but it didn't work." Mike knew that students sometimes make mistakes when typing. So he suggested that the student retype (重新输入) "R", "U" and "N".

    A few seconds later, the student's hand went up again. "It still doesn't work," she said. This time. Mike went to her to see what the problem was. To his surprise, he found that instead of typing "RUN", the student had typed "ARE YOU IN"!
