        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.

    Why do we like drinking water from plastic bottles? Some people think it is healthy and clean. Others drink bottled water because it's easy--you can carry it around with you. In hot countries, like Greece, we often buy bottles of cold water in the summer.

    However, making tots of plastic is not a good idea for many reasons. First of all, we need a lot of oil for plastic products. We usually use oil as a source(资源) of energy. If we reduced the number of bottles we made, we wouldn't need so much oil. Plastic bottles also pollute the environment. If we recycled all our plastic bottles, we wouldn't need so much space for rubbish dumps. But in Greece, we don't recycle much of the plastic we use. In 2006, Greeks recycled only about 10% of plastic waste. The rest became rubbish on land and in rivers and seas.

    So next time you want to throw away a plastic bottle in the litter bin, stop and think. If you recycled it, you would help the environment. But what can you do when there isn't a recycling bin near you? Well, there are lots of useful ways that you can use your bottles again. For example, an empty bottle makes a great piggy bank for your pocket money, and if you cut a bottle in half, you will have a plant pot. Go green! You can make a difference.

    There are lots of objects that we see in the sky. During the day we see the sun. After the sunset in the evening, we see mostly the stars. Not all the lights in the sky that we see are really stars.

    Of course, we see the moon. Some of the other lights in the sky are planets. Planets revolve (转动) around the sun like earth does.

    Once in a while someone will see what they call a shooting star.

    Shooting star looks like a star that is moving quickly across the sky. Some people believe that seeing a shooting star will bring them good luck. It's hard to find shooting star because they disappear fast.

    The correct name for a shooting star is meteor. Besides very large objects like stars, planets and moons, space has lots of little objects. These can be rocks in space left over from old planets.

    These objects can even be as small as dust. These objects are called meteorites(陨石).

    When a meteorite gets close to the earth, it gets pulled towards the earth by gravity. Earth is surrounded by atmosphere. Atmosphere is made up of air and clouds. A meteorite blows up in the earth's atmosphere. This makes the short bright moving light in the night sky. A meteorite thus turns into a meteor.
