Raising chickens seems a difficult task for teenagers. Gracie Goodpasture, from Virginia, US, not only raises them, but also tries to breed (喂养) the “perfect chicken”. And she even won an award for her love of science.

      Gracie started breeding chickens in her third grade at Steward School. At first, she worked on some farms for her school project. But later, the 14-year-old started to have some ideas of her own.

    “Some have thicker eggshells (蛋壳), and they're hearty (健壮的) throughout the winter,” said Grade.

      Since then, the young science lover started to try to find the healthiest free-range (散养) chickens. And she ended up breeding a type that now bears her name.

      The National Science Teachers Association (NSTA) gave the 2015 Angela Award to Gracie Goodpasture. Her interests don't end with chickens and eggs. She is also into building robots and testing preservatives (防腐剂) in fast foods. In her words, she wants to go to Virginia Tech for poultry (家禽) sciences in the future.

    Good morning, boys and girl. Today I'll talk about going online.

    We know that there are too many net bars around us. The Internet can make our lives interesting and enjoyable. Many of us like going online very much because we can learn how to use the computer. We can learn English and read some newspapers and magazines to know more information around us. It can make us clever in playing computer games. Also we can send e-mails to our friends quickly. It can help us contact(联络，联系) people from all over the world.

    But some students spend too much time in playing computer games and some stay in the net bars all day and all night. Some girls even get to have boyfriends or some boys get to have girlfriends online. They write too many letters to each other. It takes them too much time to chat online so they do worse in their lessons and they don't study well any more.

    I think we mustn't get online when it is time for us to study. We can do it in summer or winter holidays. I think we should get online with our teachers or parents.

    At the same time, if we have lots of free time, we can do some activities after class. We usually have activities from 4：50 to 5：50 in the afternoon . You can play basket ball or football. We also have some interest groups in school, such as drawing, singing and dancing. We can go to the English corner on Monday afternoon. We hope we can spend more time on our subjects or on such activities that we can learn a lot from and less time on the Internet.

    Basketball players are usually very tall. Because they need to put the ball into the basket. Other sports players may be shorter than them.

    Short people often have better balance (平衡) than tall people, so they don't fall over very often. In some sports the players must have good balance, for example, table tennis, they don't need to have long legs to run fast! Some of the fast runners in the world are not very tall. Some people are tall and some are short. The tallest man in the world is 2.41 meters tall. Today young people in many countries grow taller than their parents. This is because they eat better than their parents. Good food can help children grow.
