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(天文學家). They believe intelligent life exists (存在) somewhere in the universe. They also think we sill 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(哈勃望遠鏡) 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(高倍望遠鏡) 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(信號). 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.”

3. Why was it hard to look for signs of intelligent life in the universe in the past?

       A. There were not any smaller planets.

       B. There were not any powerful telescopes. 

       C. The astronomers were not interested in them.

       D. The Milky Way didn’t exist at that time,

4. Why haven’t beings from space visited us yet according to Shostak?

       A. They’re afraid of us.             B. It’s a long way away.

       C. They don’t want to see us.       D. They don’t know how to use radio signals.

5. What does the underlined phrase “l(fā)ife forms” in the last paragraph mean?
