    Microblogs are getting more and more popular with teenagers these days. Different people have different opinions on microblogs.

    Fraser Island is in Queensland, Australia, about 200 kilometers north of Brisbane. It is about 120 kilometers long and 24 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 sand blows. 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 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 may need official papers to drive there.

    You may know the song Happy Birthday very well. But do you know about its writer? It was written by an American girl. And she became very rich after that.

    When she was a child, she was poor. Once, she was invited to her friend's birthday party. She was pleased but sad because she didn't have enough money to buy a gift for her.

    "The party is coming soon, but now w I have little money." Tears ran down her face.

    Later that night she was in bed, thinking about the gift when the door opened and her grandma came in. "What happened?" her grandma asked. Hearing the girl's story, she said, "Don't worry. I think I can help you. How about singing a song together? Happy birthday to....." What a beautiful song! They sang and sang. Suddenly she woke up. It was a dream! She decided to write it down at once and sing it to her friends at the party.

    When she sang the song at the party the next day, her friends were very happy. "How wonderfully you sing! We haven't heard such a beautiful song before. Thank you for giving me the special gift," said her friend. And they learnt to sing it together. Later the girl became well-known in America.
