Johnny Smith was a good math student at a high school.
He loved his computer. He came home early every day, then he worked with it
till midnight. But Johnny was not a good English student, not good at all. He
got an F in his English class. One day after school Johnny joined his computer
to the computer in his high school office. The school office computer had the
grades of all the students: the math grades, the science grades, the grades in
arts and music, and the grades in English. He found his English grade. An F!
Johnny changed his English grade from an F to A. Johnny' parents looked at his
report card. They were very happy.
"An A in English!" said Johnny's Dad.
"You're a very clever boy, Johnny."
Johnny is a hacker（黑客）. Hackers
know how to take information from other computers and put new information in.
Using a modem（調(diào)制解調(diào)器）, they join their computers to other
computers secretly. School headmasters and teachers

own ones. And they never have to leave home to do it! They are called hackers.
