         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 (善于接受的) to such messages.
         Scientists are using powerful radio telescope 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 that 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 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 (可理解的) 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 in only about five billion years old, our galaxy is about 20
    billions years old. In that time, some scientists think it is likely that civilizations are much more advanced
    than ours. Perhaps these civilizations (文明) 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.
    1. According to the passage, how many planets in our galaxy might be inhabitable?
    A. 5 billion
    B. 10 billion
    C. 15 billion
    D. 200 billion
    2. The first paragraph in this passage is mainly about ______.
    A. how scientists are looking for signs of life on other planets
    B. why scientists are looking for signs of life on other planets
    C. where scientists are looking for signs of life on other planets
    D. when scientists are looking for signs of life on other planets
    3. The underlined word "monitor" in the passage means "______".
    A. find
    B. follow
    C. check
    D. form
    4. Which of the statements is TRUE based on the information in the passage?
    A. The earth is one of the oldest planets in our galaxy.
    B. Most scientists believe that there is intelligent life on other planet.
    C. Scientists are trying different ways to find signs of life on other planet.
    D. Scientists don't believe that there might be life on other planets.
