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?

The first written records of the ancient Olympic Games date to 776BC. The ancient Olympics were held every four years between August 6 and September 19 during a religious festival honoring Zeus( 宙 斯 ). The first modern Olympics were held in Athens, Greece, in 1896. The Olympic symbol consists of five interlaced rings of equal dimensions, representing the union of the five continents and the meeting of athletes from throughout the world at the Olympic Games. The Olympics truly took off as an international sporting event after 1924, when the 8th Olympic Games were held in Paris.

1、Passage 19Throughout her working life, a ship — like a motorcar — must be serviced regularly if she
is to remain efficient. After a period at sea she must be overall checked and any necessary repairs
must be made. There are also instances when a ship must be converted from being one kind of
carrier to another. Most of today‘s oil, for example, is carried by huge super-tankers. The smaller
tankers, many of which are still in good condition, can be converted into bulk carriers（散货船）
for the transport of sugar, coal or ore.
Conversion or repair work is carried out in a dry dock, a huge hole cut into the ground and
lined with concrete. At one end are large gates separating the dock from the river or sea. When
these gates are opened, water pours into the dock and fills it. A ship can then enter the dock, where
it is carefully fastened in an upright position.When the ship is positioned inside the dock, the gates are closed and the water is pumped out.
The vessel slowly settles on to wooden blocks. Wooden supporters are put in position between the
ship and the sides of the dock to prevent her from rolling over. Great care is taken to make sure
that the ship rests evenly on the keel（龙骨）blocks to prevent damage being done.
As soon as the ship is firmly positioned, repair or conversion work can begin on her body or
superstructure.

1、Passage 12More and more people like bicycling and it is no surprise. It is fun, healthy and good for the
environment. Maybe that‘s why there are 1.4 billion bicycles and only 400 million cars on roads
worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

Folding bikes work well for people who ride the train. Just fold the bike and take it with you.
You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take
a common bike with you when you fly. But be sure to look for information by getting on airline
websites. Not all airlines are bicycle-friendly to travelers.
