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 9What are you going to do if you are in a burning house? How will you escape? Do you know
how to save yourself? Please read the following passage.
Escaping a fire is a serious matter. Knowing what to do during a fire can save your life. It is
important to know the ways you can use and show them to everyone in the family, such as
stairways and fire escapes, but not lifts.
From the lower floors of the buildings, escaping through windows is possible, learn the best
way of leaving by windows with the last chance of serious injury.
The second floor window is usually not very high from the ground. An average person,
hanging by the finger-tips will have a drop of about six feet to the ground. It is about the height of
an average man. Of course, it is safer to jump a short way than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or
smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get
fresh air rather than smoke that may leak into the room.
On a second or third floor, the best windows for escape are those that open onto a roof. From
the roof a person can drop to the ground more safely. Dropping onto cement might end in injury.
Bushes and grass can help to break a fall.

1、Passage 13The favorite food in the United States is hamburger. The favorite place to buy a hamburger is
a fast food restaurant. At a fast food restaurant, people order their food, wait a few minutes, and

their cars or in their homes. At some fast food restaurants, people can order their food, pay for it
and pick it up without leaving their cars.
