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.

1、Passage 7Greek soldiers sent messages by turning their shields toward the sun. The flashes reflected
light could be seen several miles away. The enemy did not know what the flashes meant, but other
Greek soldiers could understand the message.
Roman soldiers in some places built long rows of signal towers. When they had a message to
send, the soldiers shouted it from tower to tower. If there were enough towers and soldiers with
loud voices, important news could be sent quickly over distance.
In Africa, people learn to send messages by beating on a series of large drums. Each drum
was kept within hearing distance of the next one. The drum beats were sent out in a special way
that all the drummers understood. Though the messages were simple, they could be sent at great
speed for hundreds of miles.
In the eighteenth century, a French engineer found a new way to send short messages. In this
way, a person held a flag in each hand and the arms were moved to various positions representing
different letters of the alphabet. It was like spelling out words with flags and arms.
Over a long period of time, people sent messages by all these different ways. However, not
until the telephone was invented in America in the nineteenth century could people send speeches
sounds over a great distance in just a few seconds.
