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.3. Stoll was concerned about a 75 cents mistake because ________.
A. every cent was important to the company
B. it might lead to a greater loss for the company
C. he was afraid the computer system might break down some day
D. he realized someone had broken into the computer system

1、Passage 4Do you know who Benjamin Banneker was and what he did? Benjamin Banneker was a
self-educated scientist at a time when most African Americans were slaves. Born a free black man
in the British Colony of Maryland in 1731, he received some formal education, but he mostly
borrowed books and taught himself science and mathematics. At 22, he borrowed a pocket watch,
and without any training, figured out how to carve a working wooden clock that chimed each hour. Because of this clock, he became well known and people would visit him just to see his creation.
Banneker ran his family farm from many years, but when he was in his late 50s, a neighbor‘s
son lent him a telescope. He became interested in astronomy, the study of the planets and stars,
and again taught himself a new science. He made calculations of tides, sunrises and sunsets, and
even predicted an eclipse. For several years he published an almanac of these calculations. Today,
he is best known for publishing six almanacs, called ―Benjamin Banneker‘s Almanac‖ between
1792 and 1797.
In the 1790s, Banneker also helped survey and lay out the land for Washington, D. C., which
became the nation‘s capital. For a look at Banneker‘s amazing life, visit the Benjamin Banneker
Historical Park & Museum in Ellicott City, Maryland.
1. What was the status of most African-Americans at Banneker‘s time?
A. Most African-Americans could have formal education.
B. Most African-Americans could be self-educated.
C. Most African-Americans had freedom.
D. Most African-Americans were slaves.

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!
Get on a bicycle and ride around your neighborhood. You may discover something new all
around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You
can bike to work and benefit from the enjoyable exercise without polluting the environment. You
don‘t even have to ride all the way.
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.
Health Benefits of Bicycling:
It helps to prevent heart diseases.
It helps to control your weight.
A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a
year.
It can improve your mood.

self-confident.
