1、Passage 5Today anyone will accept money in exchange for goods and services. People use money to
buy food, furniture, books, bicycles and hundreds of others they need or want. When they work,
they usually get paid in money.
Most of the money today is made of metal paper. But people used to use all kinds of things as
money. One of the first kinds of money was shells. Shells were not the only things used as money.
In China, cloth and knives were used. In the Philippine Islands, rice was used as money. In parts of
Africa, cattle were one of the earliest money. Other animals were used as money too.
The first metal coins were made in China. They were round and had a square hole in the
center. People strung them together and carried them from place to place. Different countries have
used different metals and designs for their money. The first coins in England were made of tin.
Sweden and Russia used copper to make their money. Later, other countries began to make coins
of gold and silver.
But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper
money looked more like a note from one person to another than paper money used today.
Money has had an interesting history from the days of shell money until today.

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?
