On October 12, 1987, some Chinese scientists were working at the computers to look for information they needed. Suddenly they saw a lot of very bright spots(点 )crossing the computers’ 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(恐惧), they found out that most of their stored information was got rid of( 除掉) by computer viruses! Obviously all these computers had been infected（感染 ） by computer viruses.
It is said that the computer viruses were made by a group of young man 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 function(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(传播) to a list of computers. Among the countries that suffering computer viruses are Britain, Australia, Switzerland and the U.S. But till now, how to get rid of the terrible remains a problem.

Edith Cavell
was born on December 4, 1865, in England. When she left school, she became a
teacher. Edith soon found that she had a 36 for nursing(护理), so she completed her

There, she took care of them and 44 them from the German
forces. Then she heard some 45 people were willing to help
the soldiers escape. Together they organized travels for the soldiers out of
Belgium to Holland, which was a safe country during the whole war.
In august
1915, the German government discovered 46 was happening at
Edith’s training school. Edith was 47 for helping about two
hundred British and French 48 escape. Early on October 12, 1915,
Edith Cavell was 49 . She died for her country, but she
believed that she had only been a nurse trying to do her 50 . History
will remember her for ever.
