3. Passage 20 Clifford 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. 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

2. Passage 7 Greek 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. Which of the following statements is true?
A. Neither the Greek soldiers nor their enemy could understand the message.
B. African soldiers shouted from tower to tower to pass message.
C. Telephone was invented by a French engineer.
D. Only by using telephone could people send speech sounds quickly.

10、Translation 10 If you are feeling that life just cannot be any worse for you, it can be challenging to think positive thoughts. When we are stressed, depressed, upset, or otherwise in a negative state of mind because we perceive that “bad things” keep happening to us, it is important to shift those negative thoughts to something positive. If you start with one small, positive thing and repeat it during the course of your day, you will begin to move into a more positive situation: positive thoughts, feelings, opportunities and people will start showing up in your life. With practice, you will find that over time, you will change your outlook and choose to be happy, regardless of the events around you.
