        When we feel the ground moves suddenly, it means that an earthquake may come. Many of the earthquakes first come under the sea and then happen anywhere on the earth. Especially they often happen near the mountains and seas such as Wenchuan, Japan and Indonesia.

        When an earthquake happens, it's very easy to cause a tsunami (海啸). Houses fall down, many people are injured and even died.

        Now scientists are trying their best to study earthquakes. They make maps to show the “earthquake belts (地震带)”. So the houses there must be quite strong.

        We believe that scientists will be able to tell us when and where an earthquake will happen in the near future. Also, they can tell us what to do and how to do. People can even use earthquakes to do something for us humans.

    Anyone who has had a long-term illness knows that recovering at home can be boring. This can be especially true for children. They may feel cut off from their friends and classmates. Now, these children may have a high-tech friend to help feel less lonely. That friend is a robot.

    The robot is called Avatarl (AV1). It takes their place at school. Through the robot, the children can hear their teachers and friends. They can also take part in classes from wherever they are recovering. And the children's school friends must help. They carry the robot between classes and place the robot in the classroom.

    A Norwegian(挪威的) company called “No Isolation” created the robot. There are another two co-founders, Karen Dolva and Marious Aabel. Dolva explains how the robot works. She says from home the child uses an iPad or a phone to start it, control the robot's movements with touch and talk through it. The child can take part in classroom activities. The robot is equipped with speakers, microphones and cameras that make communication easy. So it's the eyes, the ears and the voice of the child at school. Inside AV1 there is a small computer connected to a 4G network.

    AV1 is designed to be tough. It won't allow water to pass through it and can take a fall from a desk without damage. AV1 is large and looks like a human for a reason. Dolva says it can't be just a tiny camera because the other kids can't pick it up and take it with them. This is important because the robot is supposed to be a friend to the children. Hopefully AV1 will help some children feel less lonely while they were absent from class.

    People don't like trash. Trash is smelly, dirty, ugly, broken and useless. That's why we throw it out. But everyone knows that trash influences our environment. It can pollute our land, water and air. So it's important to recycle our trash as much as possible.

    Some Americans were very interested in recycling and they were curious about what really happened to their trash. So, what did they do? They became detectives and decided to "Follow that trash!"

    They took some items out of their recycling bin and put electronic tags (标签) on them. The tags sent signals to a computer so people could follow their trash on its journey. They found that some trash only travelled a few kilometers but much of it went into landfills.

    Waste management companies in America think this detective work will be helpful to them. Dealing with waste is very expensive and this u trash tracking" will help them to become more useful. It will save their time and money.

    However, the trash detectives say it's also important to reduce the amount of trash we produce. After all, if we produce less waste, we won't have to worry about where it goes.

    Did you know that each day one person in the USA throws away 4.4 pounds of rubbish? Almost every month, we throw away our own rubbish in packaging alone. Packaging (including boxes, bags, etc.) comes to our homes with the things we have bought. Several weeks ago, the TV news said that in a city in Italy tons of rubbish were piled up in the streets, and the smell was rather terrible. What can we do to help? We should get to know the following Rs.

    Reduce To reduce means to make less rubbish. That is one of the first things we all should do for the environment. Reduce your rubbish by doing things like packing your lunch in reusable containers(可再利用的容器), taking smaller portions(份) at dinner so you don't waste food when you have had enough, writing on both sides of paper, and using less water when taking a shower.

    Reuse to reuse is to use things again. Think about the bags you get from the shop. They can be reused to carry your lunch, to hold your rubbish, or to collect used cans. You can even take them back to the school next time to carry your things instead of getting a new bag!

    Recycle(回收利用) Recycling is an important part of keeping our planet clean and green. It can also save energy. Be sure that you don't throw things in the rubbish bins that can be recycled to make something else Paper, plastic, cans and bottles can all be recycled. But food, electrical waste and mobile phones cant. When you are not sure whether something can be recycled, go to your parents and teachers for advice.

Follow the three Rs, and every one of us can do something to save the Earth. It is also the best way to save ourselves.

    When you carry your heavy schoolbag on the way to school or home, do you know the fact that the heavy schoolbag influences your interest in learning knowledge? Don't worry. You may be able to say goodbye to your heavy schoolbag in the near future.

    Instead of burying(埋葬) your face in an ocean of textbooks, newspapers, magazines and novels, you will soon find that an E-book reader can take the place of them all.

    An E-book reader is a new kind of mini machine designed to hold thousands of text files and display them on the screen as real text printed(印刷) on a paper page.

    In the same way in which the iPod(a kind of MP3) has changed the way people enjoy music, E-book readers could change the way that books are read. Some scientists have predicted that E-books will be used widely in our daily life, especially in schools.

    The size of an E-book reader is the same as that of real books. Its screen is different from that of a computer. It is as thin as a piece of paper. The words on an E-book reader's screen look exactly the same as those on real pages. However, you can do more with an E-book reader than you can with a real book. The reader can change the size of the words and connect to the Internet to download new books.
