Do you believe that there might be life on other planets? Would you like to be the first “Earthling” to get in touch with an alien? Well, you can start your search from home. All you need is a  computer and the Internet, and you can join the project of the US-based  National Aeronautics and Space Administration(NASA).

   NASA started the Search for Extra-Terrestrial Intelligence (SETI) project eight years ago. Its goal is to examine the radio signals (信號) from nearby stars. Researchers believe that a large number of stars in the universe could have planets orbiting (circling) around them. And they want to know if these planets have conditions suitable for life forms.

   How does the project work? There is a huge radio telescope with a large bowl-shaped dish at Arecibo, Puerto Rico. It catches radio signals which are then fed in to SETI computers. The researchers have to study thousands of radio signals daily. They are looking for signals whose patterns (模式）would show the existence（存在）of hydrogen or water molecules that are necessary for life on Earth. They could be at it for years before showing a single positive result!

   Of course, even the researchers know that they cannot do a fast job on their own. So they want as many helpers as possible. Even you ! To join search, just download SETI’s free software (SETI @home). What happens next is fun. While you are away from your computer, the SETI program in your computer downloads the information on radio signals received by the radio telescope. It studies the information and send the result back to the research center.

   There are other benefits too of having the SETI project software in your computer. When you leave your computer unattended, instead of seeing the usual screen saver, you can feast your eyes on an amazing 3-D chart on the screen. This shows that your computer is busy studying SETI data and searching for signs of alien life!

   More than 1824500 people around the world are currently in the program and more are joining in every day. It’s slim chance, but wouldn’t it be fantastic if your computer were to be the first to discover an alien signal!

People of Burlington are being disturbed by the sound of bells. Four students from Burlington College of Higher Education are in the bell tower of the church and have made up their minds to    15   the bells nonstop for two weeks as a protest（抗議） against heavy trucks which run    16   through the narrow High Street.“They not only make it    17   to sleep at night, but they are doing damage（損害） to our houses and shops of historical   18  ,”
said John Norris, one of the protesters.
“ 19  we must have these noisy trucks on the roads,” said Jean Lacey, a biology student, “why don’t they build a new road that goes round the town? Burlington isn’t much more than a  20    village. Its streets were never meant for heavy traffic”.
　　Harry Fields also studying    21    said they wanted to make as much noise as possible to force the government officials to realize what everybody was having to stand. “Most of them don’t live here anyway,” he said, “they come in for meetings and the Town Hall is soundproof（隔音的）, so they probably don’t    22   . It’s high time they realized the problem.” The fourth student, Liza Vernum, said she thought the public were mostly on their side, and even if they weren’t they soon would be.
　　I asked if they were    23    that the police might come to stop them.
　　“Not really,” she said, “actually we are suitable bellringers. I mean we are assistant bellringers for the church. There is no    24    against practising.”
I left the church with the sound of the bells ringing in my ears.
