For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages.
Scientists are using powerful radio telescopes to listen to signals from about 1, 000 stars, all within 100 light years of earth. In addition, they will scan（扫视）the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal they stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy（银河星系）, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution（进化）of life. Based on the inhabitable（that can be lived in）planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent（有智力的）life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time, some scientists think it is likely that civilization（文明）much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.

I lived in Dallas, Texas nearly all my life with my mom, dad and older sister. We were1to respect others, value education, and get all that we could out of life. My parents always say, “2hard and the world is yours.” They are never without a3word of advice or a bit of encouragement when life gets tough.
My parents always4me to go to college. However, when I5at 16 years old that I’d rather get married to a man than go to college, they6stopped telling me they loved me and I could anything I wanted to.7, they persuaded me. I graduated from high school and currently 8the University of Oklahoma studying medicine. I want to make the 9a better place to live in.
Every time I call home to tell them about a10I received in Chemistry Lab or Microeconomics or whichever11it is that I’m working hardest for at the moment, they tell me how12of me they are. I know there are college kids out there that have no one to call home when they an “A” on a project and I feel incredibly13to have my parents.
Don’t get me wrong: We’ve had our share of14. I was the angry teenager and they were the awful15that wouldn’t let me stay out all night or let me get my tongue pierced(扎洞).But somehow, we 16to work through those issues. They never17loving in me or believing in me.
I 18everything I am to my parents. Without their19love and encouragement, I wouldn’t believe I can change the world. My parents taught me to always20for what I believe in. So I’m working toward something really great and can only hope I continue to make them proud.
