Is there intelligent(有智力的)life on other planets? For years, scientists said "no." or "we don't know." But today this is changing. Seth Shostak and Alexandra Barnett are astronomers(天文学家). They believe intelligent life exists(存在)somewhere in the universe. They also think we will soon contact these beings(人;生物).
Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. "This is long enough for other planets to have intelligent life," say Shostak and Barnett. The second reason is size—the universe is huge. "Tools like the Hubble Telescope(哈勃望远镜)have shown that there are at least 100 billion galaxies, " says Shostak. "And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth."
In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes(高倍望远镜)allow scientists to discover smaller planets——the size of Mars or Earth—in other solar systems. These planets might have intelligent life.
Have beings from space already visited Earth? "Probably not," says Shostak. "It's a long way away. However, intelligent beings may contact us in other way, such as radio signals(信号). In fact, they may be trying to communicate with us now, but we don't have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other."
The Chinese dragon is one of the most important parts in Chinese culture. Chinese dragons look like a combination (结合体) of many animals such as snakes, fish and deer in Chinese culture. They have two horns (角) and a long body. They also have fantastic powers—they can fly in the sky, swim in the sea and can even make rain.
The Chinese dragon is a symbol of strength and good luck. The emperors of ancient China loved dragons. Their clothes were covered with pictures of dragons.
We are proud to call ourselves the "descendants (传人) of the dragon". In Chinese, excellent people are often called "dragons". A number of Chinese sayings talk about dragons. For example, "Hope one's child will become a dragon" means hoping he or she will be successful.
It is said that people born in the Year of the Dragon are creative, active, brave and it's easier for them to get angry. There are also some traditional festivals about dragons in China, such as the Dragon Head-raising Day and the Dragon Boat Festival. The festivals are celebrated differently by us. These two festival s come every year, but the Year of the Dragon comes every twelve years.
People who are interested in Chinese culture may study dragons and it will be helpful for them to have a better understanding of Chinese culture. As the "descendants of the dragon", it is our duty to work together to pass our traditional culture on to more and more people.
