When you look up into the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time.
Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.
The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.
This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better.

Up in the Sky
Take a trip up a hill on a windy day. What is flying high in the sky? It isn’t a bird or a plane. It is a kite!
Kids and adults like flying kites. Long ago, the first kites were made by Chinese people. Then, people around the world began flying kites.
One story tells a man’s hat got lifted off by wind. He had fun chasing(追赶) his hat, so he did it again! His hat became the first kite. Other stories tell that people liked watching leaves on windy days. They tied leaves to strings(线) and watched them fly.
Long ago, kites became important in keeping China protected. A man might be lifted up by a kite while he spied(监视) on an enemy. He could use the kite to fly high like a plane. He could also fight from the air!
Kites come in many shapes, sizes, and styles. They are usually made of cloth or paper. A kite might be shaped like a bird, a fish, or just a box. Kites are also painted with colors.
You can use a kite to catch fish. First you tie a fishing line to a kite. Then you put bait(鱼饵) on the line. You watch the kite with hopes as it flies over the water. When you pull the kite down, you might find a fish on your line! Some people think this is more fun than using a fishing pole(杆).
Many countries have special days to honor kites. People make, sell and fly many types of kites. There are several kite festivals in China. The Beijing International Kite Festival is usually held in April every year. People spend all days flying kites. You might see famous fighter kites. People fly these kites quite fast and try to cut other flyer’s lines.
There is much to learn about kites. From long ago in China until now, kites have had many uses. They have been used for spying, fighting, and fishing. But the best way to use a kite is to fly it high for fun!
