    Fraser Island is in Queensland, Australia, about 200 kilometers north of Brisbane. It is about 120 kilometers long and 240 kilometers wide. It is a very important island because it is completely made of sand. In fact, it is the largest sand island in the world. There is no airport on the island, but there is a long beach along the east coast. Planes arrive and leave from here.

    The sand makes unusual shapes. There are hills made of sand called sandblows. Nothing grows on them. They move one or two meters a year from the northwest towards the southeast of the island, getting bigger and bigger. At other places on the island, such as Rainbow Gorge, The Cathedrals and Red Canyon, the sandy rocks have different colors. Sometimes the rocks are so brown that they turn the sea brown, like coffee.

    Surprisingly, the sandy island has a lot of different plants and animals. There are dark forests—eucalyptus woods, beautiful flowers and over a hundred lakes. There are many kinds of birds, like owls and curlews. There are many animals there, too, such as crocodiles, flying foxes and wild dogs called dingoes.

    About 500,000 people visit the island every year to see the island's beauty and nature. People enjoy camping and hiking（徒步）there. Unluckily, the visitors create problems. They damage plants and frighten animals. Their sun cream（防晒霜）makes the water dirty. So it is necessary to manage the visitors. For example, people may not use motor boats or go fishing in the lakes, and they need official papers to drive there.

Where does the wind come from? What makes the wind move(移动) all the time? Scientists tell us that it is the sun. That makes air move, and makes it blow(吹). When the sun shines on the earth, it makes the earth hot. Then the earth makes the air hot. When the air becomes hotter, it also becomes lighter(更轻). The light air goes up. Cool air comes into take the place of（代替） the hot air. The hot light air goes up higher and higher until it becomes cool. Then it comes down again, and then the earth makes it hot again, and it has to go up. When the air move, it has wind.

    Steel, concrete(混凝土) and glass are the usual materials in any skyscraper. But more high buildings are now using wood.

    In the last four years, Australia, Norway, England and Canada have all built wooden skyscrapers. The latest one is in Sweden, a new, 19-storey wooden hotel called "Sida vid Sida" (Side by Side).

    Why are wooden skyscrapers being chosen ahead of concrete ones? Let's find out.

    Is it strong enough?

    Wood has been used in many Chinese buildings for thousands of years, but is it strong enough for skyscrapers?

    "There's a lot of new materials made out of wood that are able to build big buildings," material expert Dr Michael Ramage told CNN when he was interviewed.

Architects (建筑师)have done thousands of experiment to make sure it is. They place layers of wood across one another coated with special glue to create very strong material.

Wood also lasts a long time and doesn't break down if it is well looked after. The examples include the rooftops of Beijing's Forbidden City and some 700-year-old houses in England.

Ramage also said on the internet that bamboo could be cut in special ways to make it even stronger than normal wood.

    Won't it catch fire?

    Wooden buildings sound dangerous when it comes to fire. But experts say they may be safer than concrete ones if there is a fire.

    "Wood doesn't burn in the way the public imagines," Ramage said. Very small pieces of wood catch fire easily, but very big pieces of wood are quite hard to set on fire, he said.

    Animals United is a 3D German cartoon which is directed by Reinhard Klooss and Holger Tappe. It is a story about animals that get together to find water. Along their journey, lots of funny things happen, and of course, they have a lot of adventures.

    The animals in the grasslands in Africa are waiting for the coming flood. However, this year's flood seems to come later than in other years. The animals become upset and worried. At the same time, some animals from other places come to the grasslands to look for peace. However, the situation seems worse because the water is becoming less and less. So they decide to look for the river.

    Finally, they find the reason why they don't have any water to drink. A dam(坝) has been set up so that humans can have a better life. After a long fight with humans, they let the world know that animals are in danger.

    This film is about environmental matters. The humans are the bad and the animals are the good. This film is to give humans a warning that they must not destroy the homes of animals or damage nature in order to improve their own life. Humans should know that animals also have their own world.

    Pisces is the twelfth star sign. There is a legend about its name.

    Long, long ago, there was a war between gods and a bad monster (怪物). It lasted ten years. One day, the gods were surprised to find that the monster was coming towards them. The goat god Pan shouted a warning and tried to change himself into a fish. One god, Aphrodite, took her little boy Eros and tried to hide among the bushes near Euphrates River. She was the god of love and her son was the god of war. It is said that two fish swam to carry Aphrodite and her child to safety. Some people also believe that Aphrodite and Eros changed into fish themselves and swam away to safety. Later the fish represent Aphrodite and her son Eros.

    As they appeared in the sky, the two fish were tied together by a rope (绳子). Some said that Aphrodite tied the little boy to her body so that he would not get lost as they swam away to safety. That's the story about Pisces.

    In Western countries, some people believe people will share similar characteristics if they have the same star sign. So if you're born between February 19th and March 20th, your star sign is Pisces. It means that you are generous, easy-going and creative.

An invention in front of your eyes

    What is the most important invention of all time? Is it the written word that helps us to record information? Is it the telephone that lets us talk to people from all over the world? Is it the car that lets us travel at great speeds to meet others? Umberto Eco, an Italian writer, thinks it is something quite different. He says the most important invention might be bright in front of your eyes. He is talking about a simple pair glasses.

    Modern eye glasses were invented around 1000years ago. They were more than just a convenient way to read. Before glasses, writers, scientists or teachers who could not see properly had to memorize everything. After about ten years of poor eyesight, they could not remember well enough and could not work. Glasses meant that people could work in their old age.

    People who wanted to remember some information could write it down and read it. Eye glasses are one of the world's greatest inventions and were probably worn by the people who designed the first telephones and cars.
