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 Alex Barnett are astronomers (天文学家). They believe intelligent life lives somewhere in the universe. They also think we will soon contact(联系) it.
Why do Shostak and Barnett think intelligent life lives 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 Telescopes(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 the 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 find smaller planets — the size of Mars or the earth — in other solar systems. These planets might have intelligent life.
Has intelligent life from space already visited the earth? "Probably not," says Shostak. "It's a long way away. However, intelligent life may contact us in other ways, such as radio. 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."

At the age of 73, Chen Shaoqi n from Beijing has shown the world how life should be lived.
Although she only had a middle school education, Chen began studying English at the age of 40 and passed a college entrance exam, making herself from a factory worker to a white- collar clerk in an international trade company. Chen continued to study art after retirement(退休) and finally became an art guide at the age of 67. Over the past five years, she has guided visitors at an art center for three days a week, totaling 3,500 hours.
From an old lady who knew nothing about modern art to a volunteer guide, Chen's hard work and love for learning have encouraged many people. She said that she must continue to learn. As a guide, she is able to attend professional training courses and has the chances to learn from artists and curators (馆长), which gives her encouragement to continue.
Chen has guided many exhibitions over the years, including those of famous artists like Zeng Fanzhi, Xu Bing, Qiu Zhijie and Pab lo Picasso. She believes that every tour is a beautiful journey and a new chance to learn and be moved. Her effort of learning and her ability to mix many subjects have made her an excellent guide. After turning73 this year, she believes that the width of one's life can be expanded(扩展) through self- improvement and learning.
Chen Shaoqi n is a best example that anyone can find their passion(热爱) and then learn, grow and share with others.
