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.
B. 10 billion
C. 15 billion
D. 200 billion
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
B. follow
C. check
D. form
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.

When you are in a place where you are hunting for a new job or career, you will find that there are several things needing your atten tion. Jobs and careers are fewer than you might entirely be prepared for; especially when satisfying employment is something you need to seriously think about. How are you going to find the job that you want and how are you going to avoid traps in your way? When you want to make the most out of your job search, take a moment and think about the things that you must avoid at all costs. One of the most important rules is, never to compromise on your requirements such that it will negatively affect your life and peace of mind at a later stage. Keep in mind your basic expectations from a job. It might be something along the lines of increased monetary pay ment or you might find that it has something to do with benefits or time off. Whatever it is that you count as your basic requirements, make sure that you do not accept a job without it. Your requirements might be difficult to get, but you have all the rights to try and a chieve them. That being said, don't shy away from odd jobs that might actu ally take you to the place that you want to be in, eventually. Some- times, finding the right job is a matter of luck and chance after you have been searching and putting in a lot of efforts. And if something unexpected happens, remember that taking chances is something you might want to seriously consider. You are in a place where you are thinking about moving forward, so don't be surprised by what route it might take to get there. As long as you keep your goals in mind, you are going to be doing much better than other people are during their job search. If you are looking for the right career, another thing that you can do to make sure that you get the right kind of employment is to advertise yourself. When you do nothing to push yourself forward, you will be the one suffering for it. If required, motivate yourself and try to look at all that you possess by way of positive traits. Make sure that you can present your skills and abilities in the best light possi ble. If the jobs that you have set your sights on are challenging, set targets for yourself and work towards them in a systematic and fo cused manner. The more efforts you put into marketing yourself, the better will be your chances of obtaining the job of your choice. Remember that when you are working on a job search, you should not shortchange yourself. This is because you will only hurt yourself by aiming low. What to avoid during your job search | ||||||||
