IV. 阅读理解（共15小题；每小题2分,满分30分）
Every year when the Italian artist Michelangelo’s (1475－1564，意大利文艺复兴时期著名雕刻家、画家、建筑师) birthday es around, puter users all over the world are filled with fear (害怕) and use their puters with care. Some may even choose not to turn on their puters on March 3. All this fear and care are just because a deadly puter virus is ready to cause damages on that day.
What’s a puter virus then? Why do people get so afraid of it?
A puter virus is, in fact, a little program that is put into other programs and that does something bad. It is called a virus because, like any real-life viruses such as AIDs virus, it reproduces itself. And when these programs are run, the virus is brought to life. It hides itself in your puter system waiting for the right moment to make damages. And at the same time it keeps producing itself by copying itself onto other programs.
The Michelangelo virus waits until the artist’s birthday es around, and then it will wake up to do very bad things like destroying you files (毁坏文档) . So next time when you turn on your puter, look out for puter viruses!
