Is there intelligent 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. They believe intelligent life exists(存在)somewhere in the universe. They also think we will soon contact these beings.

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 Milk 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 ways,such as radio signs. 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. "

I am Jay from Sunshine Middle School. Recently, we did a survey about who we prefer to share worries with. We got different answers. According to the chart, about 71% of the students would like to share their worries with their classmates and friends . It is mainly because they believe that if people are at the same age, they are easy to communicate and understand each other better.

About 22% of the students said they would like to share worries with their teachers and parents. According to them, adults are rich in experience, and that they can deal with their problems easily. The rest prefer to keep worries to themselves. As for them, it’s a struggle to get along well with others, some of them said they didn’t want to trust anyone.

As far as I am concerned, I am willing to share worries with my best friends because they’re always kind and understanding. However, if I meet with some serious problems, I’ll be likely to ask my parents and teachers for help, who, I believe, have more experience to give me valuable advice.
