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 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.”

A team of US psychologists(心理学家) have found that talking to another person for ten minutes a day helps with memory.
“Socializing(交际) is just as effective as more traditional kinds of mental exercise in boosting memory and intellectual(智力的) performance,” Oscar Ybarra, a psychologist at the University of Michigan Institute for Social Research, said in a statement.
In one investigation, they analyzed data on 3610 people, aged 24 to 96.
They found that the higher their level of social interaction(交流), the better their cognitive(认知的) functioning. Social interaction includes getting together or having phone chats with relatives, friends and neighbors.
In another experiment, the researchers conducted laboratory tests on 76 college students, aged 18 to 21, to evaluate(评估) how social interactions and intellectual exercises affected the results of memory and mental performance tests.
The students were divided into three groups: the social interaction group had a discussion of a social issue for 10 minutes before taking the tests; the intellectual activities group completed three tasks (including a reading comprehension exercise and a crossword puzzle) before the tests; and a control group(对照组) watched a 10-minute clip(电影片段) of the Seinfeld television show.
“We found that short-term social interaction lasting for just 10 minutes improved participants’ (参与者) intellectual performance as much as engaging in (从事) so-called ‘intellectual’ activities for the same amount of time,” Ybarra said.
The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin.
1.What does the underlined word “boosting” in the second paragraph probably mean?
A. Improving. B. Reducing.
C. Preventing. D. Training.
2.Which is not included in social interaction?
A. Having a talk with a neighbor.
B. Attending a birthday party.
C. Watching TV at home alone.
D. Calling your classmates.
3.What’s the purpose of the experiment on 76 college students?
A. To judge the effect of social interaction on memory and intelligence.
B. To find out what is real social interaction.
C. To learn how much time is needed for social interaction.
D. To show the function of people's cognition.
4.What’s the main idea of the passage?
A. Intellectual exercises make your memory better.
B. Different people have different ways of communication.
C. Communicating with others keeps you healthy.
D. Social interaction makes you smart.

I once had a hard time making a living in France. Three years ago, I moved to a new neighborhood and felt an intense(强烈的) need to meet people so I went to the cinema. Outside the cinema was a woman with long gray hair who had a strong smell and was asking for money. I reached for my wallet to give her a Euro and then something made me stop and enter into conversation with her. I said, “Look, all the women going to the cinema here on a Tuesday night are seeing a film that can change your life. I’d rather buy you a ticket than give you money.”
She hesitated（犹豫） for a moment and then came in with me. She hid behind me because, she said, the people running the theater didn’t like her. I got her a ticket and she sat next to me. There were about 80 women there; I noticed some of them were turning around and looking at me with expressions of surprise and curiosity(好奇心).
I encouraged the woman I had bought the ticket for to come the following night to an event where there would be many representatives(代表) of various social services. I thought they could be of some help to her. She did come and I was able to direct her to an agency that helped women in her situation. At the same time, a woman came toward me and said, “Are you the person who bought a ticket for the woman outside the theater asking for handouts?” When I said yes she said, “I want you to come to the community center where I work. I want the other employees there to meet you.”
This was the beginning of a deep friendship and colleague relationship. I now have a great job and have more work than I’ve ever had in my 20 years in France. And the woman I took to the cinema that night? I learned that she was not homeless and that she was a secretary.

A. She wanted to see a film without a ticket.
B. Her body gave out a pleasant smell.
