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. The passage is mainly about ________.

1、Passage 2
Man has always wanted to fly. Some of the greatest men in history had thought about the problem. One of them, for example, was the great Italian artist, Leonardo Da Vinci. In the 16th century he made designs for machines that would fly, but they were never built.
Throughout history, other less famous men had wanted to fly. An example was a man in England 800 years ago. He made a pair of wings from chicken feathers. Then he fixed them to his body and jumped into air from a tall building. He did not fly very far. Instead, he fell to the ground and broke every bone of his body and rested in peace.
The first real step took place in France, in 1783. Two brothers, the Montgolfiers, made a very large ―hot air balloon‖. They knew that hot air rises. Why not fill a balloon with it? The balloon was made of cloth and paper. In September of that year, the King and Queen of France came to see the balloon. They watched it carry the very first air passengers into the sky. The passengers were a sheep and a chicken. We do not know how they felt about the trip. But we do know that the trip lasted eight minutes and that the animals landed safely. Two months later, two men did the same thing. They rose above Paris in a balloon of the same kind. Their trip lasted twenty-five minutes and they traveled about.3.In fact, the Englishman who tried to fly.

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.
1. According to this passage, the Roman way of communication depended very much upon
_________.

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.3. Which of the following escaping way is NOT right?

198.She won‘t be afraid as( )as you are here.

113.Not until she arrived at the meeting room( )she had forgotten to bring the document.

1、Passage 6Community service is an important component of education here at our university. We
encourage all students to volunteer for at least one community activity before they graduate. A
new community program called ―One On One‖ helps elementary students who‘ve fallen behind.
Your education majors might be especially interested in it because it offers the opportunity to do
some teaching, that is, tutoring in Math and English.
You‘d have to volunteer two hours a week for one semester. You can choose help a child with
Math, English, or both. Half-hour lesson are fine, so you could do a half hour of each subject two
days a week.
Professor Dodge will act as a mentor to the tutors ---- he‘ll be available to help you with
lesson plans or to offer suggestions for activities. He has office hours every Tuesday and Thursday
afternoon. You can sign up for the program with him and begin the tutoring next week.
I‘m sure you will enjoy this community service and you‘ll gain valuable experience at the
same time. It looks good on your resume, too, showing that you‘ve had experience with children
and that you care about your community. If you‘d like to sign up, or if you have any questions, stop by Professor Dodge‘s office this week.
