    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).

I've loved my mother's desk since I was just tall enough to see above the top of it as mother sat doing letters. Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing must be the most wonderful thing in the world. Years later, during her final illness, mother kept different things for my sister and brother. “But the desk,” she would say again, “it's for Elizabeth.” I never saw her be angry, and never saw her cry. I knew she loved me—she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter. They never happened. And a gulf opened between us. I was “too emotional(易动感情的)”. But she lived “on the surface(表面)”. As years passed I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive(原谅) me. I posted the letter and waited for her answer. None came. My hope turned to disappointment(失望), then little interest and, finally, peace— it seemed that nothing happened. I couldn't be sure that the letter had even got to mother. I only knew that I had written it, and I could stop trying to make her into someone she was not. Now the present of her desk told, as she'd never been able to, that she was pleased that writing was my chosen work. I cleaned the desk carefully and found some papers inside —a photo of my father and a one-page letter, folded(折叠) and refolded many times. Give me an answer, my letter asks, in any way you choose. Mother, you always chose the act that speaks louder than words.

    We spent a day in the country and picked a lot of flowers. Our car was full of flowers inside! On the way home we had to stop at traffic lights, and there my wife saw the bookshelf. It stood outside a furniture（家具） shop. "Buy it," she said at once. "We'll carry it home on the roof-rack（车顶架）. I've always wanted one like that." What could I do? Ten minutes later I was twenty dollars poorer, and the bookshelf was tied on to the roof rack. It was tall and narrow, quite heavy too.  As it was getting darker, I drove slowly. Other drivers seemed more polite than usual that evening. The police even stopped traffic to let us through. Carrying furniture was a good idea. After a time my wife said, "There's a long line of cars behind. Why don't they overtake（超车）?" Just at that time a police car did overtake. The two officers（警官） inside looked at us seriously when they went past. But then, with a kind smile they asked us to follow their car through the busy traffic. The police car stopped at our village church（教堂）. One of the officers came to me. "Right, sir," he said. "Do you need any more help now?" I didn't quite understand. "Thanks, officer," I said. "You've been very kind. I live just down the road." He was looking at our things: first at the flowers, then at the bookshelf. "Well, well," he said and laughed. "It's a bookshelf you've got there! We thought it was--er, something else." My wife began to laugh. Suddenly I understood why the police drove here. I smiled at the officer. "Yes, it's a bookshelf, but thanks again." I drove home as fast as I could.

    Billy's favorite color is orange. But he can't see what orange looks like. Billy is blind.

    A month after he was born, his mother noticed that his eyes weren't quite as big as a normal baby's. “Billy would never be able to see.” the doctor told his mother. After that Billy's mother began talking to him, describing things she saw outside the window. She described everything to him.

    Billy does not only depend on his mother's descriptions to learn about the world around him. He sees with his cars and his hands, too. He has perfect hearing. When people make phone calls, he can tell the numbers they dial(拨).

    Billy loves computer science. He began teaching himself computer programming when he was just seven years old. His dream school would be Stanford University. He gets top grades in his classes, making that a real possibility.

    “You can't let excuses get in the way of your dreams, and if you do that you can't move forward and reach your goals, “said Billy.

    Something caught my eyes when I was walking down the street. Two silver coins were shining in a melting snow bank, so I dug through the snow looking for more. Of course, I just ended up with really cold hands. I slipped the two coins into my pocket and went home, colder but richer. I began to think about how to spend the money.

    Two days later, Mary and her little sister were searching the snow banks. "Finders are keepers" was my first thought. I didn't want to hand them out even though Susy was already crying." I dropped them right here," she said between tears. Her hands were cold and red for digging in the snow. "Maybe they slid down the street with the melting snow. Let's dig over here. "Mary's voice sounded confident.

    "They'll never know" was my second thought, and I walked past them. "Phil, have you seen two silver coins?" asked Mary. Susy looked up from digging. Her eyes were hopeful.

    "Tell a lie" was my third thought. As a matter of fact, I hesitated," I dug two coins out of that snow bank just a few days ago. I wondered who might have lost them." Susy hugged me with a big smile, "Oh, thank you, thank you."

    Mr. Jones had a nice Brown coat. He loved it very much, but his wife didn't like it. Because it was old. She often said." Give it to a poor man." But Mr. Jones always answered," No, I like this coat. "

    Then a cigarette（香烟） fell on it and made a hole in it. So Mrs Jones said, "Please don't wear it again." Mr. Jones took it to a small tailor（裁缝） "Please make another coat like this one." The tailor made the coat very carefully. Then he lit （点燃）a cigarette, and made a hole in it in the same place.
