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.

    Bird lovers know that a good place to go bird-watching is Guandu Nature Park. As many as 220 kinds of birds come to this park every year. Since the park offers birds lots of food to eat and places to build their nests, it has become a paradise（天堂）for birds.

    Guandu Nature Park is also a great outdoor classroom. The park's Nature Center provides guided tours to the public. During the tour, visitors can learn about the environment. So, if you want to have a fun and educational weekend, come to Guandu Nature Park. Get away from city life and head into nature.

    Read the passage carefully and complete the table with only one word for each blank.

    Back in the twentieth century, robots seemed to have a big future, at least in the movies. Like the robots servants in the Star War movies. It looked as if one day robots would do all the boring or dangerous jobs while the humans sat around doing something more interesting. But people were also frightened that robots might become the bosses, not the servants.

    Has it happened? You're still unlikely to see a robot walking around your town but that doesn't mean they don't exist. Robots are used in car making, and in areas which are dangerous for humans, in bomb producing and deep-sea discovering, for example. We employ robots instead of doing the job ourselves. According to the report, there are 750,000 working robots in the world today.

    These working robots definitely look like machines but many scientists are now trying to make robots look more similar to humans. So what will robots be able to do by the year 2030? There are already plans to use robots in hospitals and old people's homes. Robot nurses will remind patients to take their medicine or tell a doctor if the patient needs attention. But many people are worried about the idea of robots looking after the old, the sick and the very young, separating them from important human contact. It may also create unemployment. It is really possible that robots will be used for many jobs in areas.

    But can we be sure that the next generation robots will always follow human orders? Or even destroy them? Or will we be able to create robots with emotions? Only the future will tell.

    In English, people use many expressions(表达) with the word "dog". People in the west love their dogs and treat them well. Dogs without owners to care for them lead a very different kind of life: The expression' to lead a dog's life" means living an unhappy life.

    Some people say we live in a dog-eat-dog world. That means many people are competing the same things, like good jobs. They say if a person wants to be successful he has to work like a dog. This means they have to work very hard. Such hard work can make people dog-tired. And, this situation would be even worse if they became ill as a dog.

    Sometimes we should let a sleeping dog lie, which means we'd better not trouble a person who may cause problems. And if someone says you are a lucky dog, he is just saying you're very lucky.

    Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people Often have to learn new skills(技能) . Yet, some people say that it's always impossible to teach an old dog new skills. They believe that older people do not like to learn new things and will not change the way they do things.

    There are also some other dog expressions. The dog days of summer are the hottest of the year. A rain in summer may cool the weather. But we do not want to have a very heavy rain. In other words, we do not want it to rain cats and dogs.

    What's your favourite animal? Monkeys, zebras or……Now, let me tell you something about pandas. They come from China. Their heads and stomachs(腹部)are white, and their legs are black. Their black eyes are like a pair of black glass balls. Pandas like living in bamboo woods(树林), because the place is cool①并且它们通常吃竹子.

    Pandas are lovely, but they are in danger(危险). ②People cut down(砍倒)lots of bamboos to build houses. Please save the lovely pandas. Let's try our best to help them.
