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.5.When did two Frenchmen rise above Paris?

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.
2. The expression ―keep a close eye on‖ in paragraph 1 most probably means ________.
