Thang-ga is a special kind of painting. It started from the Tang Dynasty. Thang-ga paintings have attracted the public's attention in recent years. At the same time, the Chinese government has also tried hard to protect the culture.

    Thang-ga paintings were developed in the 7th century in the Tibetan area. The paintings are colourful and the paints used in Thang-ga paintings are different from those in other paintings. Because of the special environment of the Tibetan Plateau (高原) and the excellent painting skills, the colours of Thang-ga paintings look special. The paints in Thang-ga paintings in the past were made from minerals, including gold, silver, as well as some plants. Since they were made by hand, the beautiful colours could last for hundreds of years.

    However, with the development of machines, people now use cheaper and more easily-made chemicals to make paints. The traditional paints in Thang-ga paintings needed too much work and there were many secret methods. Later people stopped making the paints and forgot about them. So the skills were almost lost.

    Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves. Some birds love eating locusts (蝗虫), but birds cannot easily catch them, why? It is because locusts change their colours with the change of the colours of crops. When crops are green, locusts look green. But as the harvest (收获) time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for living and appear only at night.

    If you study animals' life, you'll find the main use of colour is to protect themselves. Bears, lions and other animals move quietly through the forests and they cannot be easily seen by hunters. This is because they have the colours much like the trees.

    Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体) when it faces danger. While the liquid spreads, its enemies cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

A Bite of China

Are you an eating-lover? Do you want to eat every delicious food in the world? Then do you watch the popular program A Bite of China? It's a TV program on Chinese delicious food which has been produced by CCTV. Is there any holiday that isn't celebrated with special festival food? Here are several traditional Chinese foods:

Noodles are a symbol of long life in Chinese culture. They are as much a part of Chinese birthday celebration as a birthday cake with its candles lit in many western countries. Since noodles mean long life, it is considered very unlucky to cut it off.

Although westerners sometimes may be very sorry to see fish lying on the plate, in China a whole fish is a symbol of richness. In fact, at a party it is a tradition to serve the whole fish last, pointed towards the most valued guest. Fish also has a special meaning because the Chinese word for fish, yu, sounds like the word for richness or plenty, and it is believed that eating fish will help your wishes come true in the year to come.

A very popular dish during the Dragon Boat Festival is Zongzi. This tasty dish is made of rice dumplings with meat, peanuts or other delicious food in bamboo leaves. The tradition of Zongzi is meant to remind us of a great man, Qu Yuan in Chinese history.

    Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk (垃圾) has become a problem in outer space too.

    According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.

    Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle.

    To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

    To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

    Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

    "The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.

    "The time to act is now. The longer we leave the problem, the bigger it will become," he says.

    Today, roller skating (滑旱冰) is easy and fun. But many years ago, it wasn't easy at all. Before 1743, people never tried skating on wheels. That changed because of a man named John Joseph Merlin. Merlin's work was making instruments. In his free time he liked to play the violin. Merlin was a man with many ideas and many dreams. People called him a dreamer.

    One day Merlin received an invitation to go to an important party. He was very pleased and a little excited. As the day of the party came near, Merlin began to think. He wanted to find a way to make a wonderful entrance at the party. Merlin had an idea. He thought that he would attract a lot of attention if he could skate into the room.

    Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skate shoes. Merlin was very proud of them. He dreamed of arriving at the party and skating into the room while playing the violin. He was sure that everyone would be very surprised.

    On the night of the party Merlin rolled into the room, playing his violin. Everyone was really surprised to see him. There was just one problem. Merlin had no way to stop his roller skating. He rolled on, playing the violin. Then, with all eyes on him, Merlin hit into a huge mirror on the wall. The mirror broke into many pieces with a very loud noise. But nobody forgot Merlin's wonderful entrance after that.
