 北京四中初三内部训练试题阅读解析
 
 
 
On October 12, 1989, some Chinese scientists were working at the computers to look for information they needed. Suddenly they saw a lot of very bright spots crossing the computerss screens. At the same time the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses (病毒)! Obviously all these computers had been infected by computer viruses.
 
  It is said that the computer viruses were made by a group of young men fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence (才智). These kinds of computer viruses are named Jerusalem(耶路撒冷)Viruses. These viruses can stay in computers for a long time. When the time comes they will attack the computers by lowering the functions (功能), damaging their normal programs or even getting rid of all the information.
 
  We now come to know that Jerusalem Viruses often attack computers on Fridays and that they are spreading to a lot of computers. Among the countries that suffered computer viruses last year are Britain, Australia, Switzerland and the U.S. But fill now , how to get rid of the terrible viruses remains a problem.
 
  56.The group of young men created the viruse to________.
 
  A. damage the computers
