1、Passage 20Clifford Stoll ran a computer system in Berkelely, California. As a system administrator, he
kept a close eye on the records. One day, Stoll found something strange in the payment record.
There was a 75 cents mistake. One of the thousands of users had used the system for 75 worth of
time and not paid for it.
It might sound like very little money to worry about. But that 75 cents was the first clue Stoll
had to a much bigger problem — that a hacker（黑客）had broken into Stoll‘s computer system.
Who was it? Stoll spent the next year trying to find out. During that time the hacker used the
system in Berkelely as a starting point to break into military computer systems all over the United
States.
Stoll had to keep track of the hacker‘s activities on the computer without the hacker‘s
knowing someone was watching him. Stoll even made up huge files of false information so the hacker would have lots to read. When the hacker spent long time reading, the telephone company
was able to trace the lines. After a year, the hacker was traced back to his computer — in
Germany. He was later caught by the German police.4. What did Stoll decide to do when he found the problem?

A. 　To report to the police.

worldwide today. Bikes can take you almost anywhere, and there is no oil cost!
Get on a bicycle and ride around your neighborhood. You may discover something new all

Folding bikes work well for people who ride the train. Just fold the bike and take it with you.
You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take
a common bike with you when you fly. But be sure to look for information by getting on airline
websites. Not all airlines are bicycle-friendly to travelers.
