    One day in 1965，when I worked at View Ridge School in Seattle，a fourth­grade teacher approached me.She had a student who finished his work before all the others and needed a challenge.“Could he help in the library？” she asked.I said, “Send him along.”
    Soon a slight，sandy­haired boy in jeans and a T­shirt appeared.“Do you have a job for me？” he asked.
    I told him about the Dewey Decimal System(杜威十进分类法) for shelving books.He picked up the idea immediately.Then I showed him a stack(摞) of cards for long­overdue books that I was beginning to think had actually been returned but were misshelved with the wrong cards in them.He said，“Is it kind of a detective job？” I answered yes，and he became working.
    He had found three books with wrong cards by the time his teacher opened the door and announced，“Time for break！”He argued for finishing the finding job；she made the case for fresh air.She won.
    The next morning，he arrived early.“I want to finish these books，”he said.At the end of the day，when he asked to be a librarian on a regular basis，it was easy to say yes.He worked untiringly.
    After a few weeks I found a note on my desk，inviting me to dinner at the boy’s home.At the end of a pleasant evening，his mother announced that the family would be moving to a neighbouring school district.Her son’s first concern，she said，was leaving the View Ridge library.“Who will find the lost books？” he asked.
    When the time came，I said an unwilling good­bye.I missed him，but not for long.A few days later he came back and joyfully announced，“The librarian over there doesn’t let boys work in the library.My mother got me transferred back to View Ridge.My dad will drop me off on his way to work.And if he can’t，I’ll walk！”
    I should have had an idea such focused determination would take that young man wherever he wanted to go.What I could not have guessed，however，was that he would become a genius of the Information Age：Bill Gates，tycoon(企业巨头) of Microsoft and America’s richest man.
    小题1:What was the author when the story happened?
    A．A teacher.B．A librarian.
    C．A detective.D．A student.
    小题2:Why was the boy sent to the library by the fourth­grade teacher?
    A．He failed to finish his work on time.
    B．He challenged the teacher in the class.
    C．He disturbed all the other students in the class.
    D．He needed something to do to challenge himself.
    小题3:What was the boy told to do on his first day in the library?
    A．To rearrange the books according to the new system.
    B．To put those overdue books back to the shelves.
    C．To find out the books with wrong cards in them.
    D．To put the cards back in the long­overdue books.
    小题4:The boy got transferred back to View Ridge because ________.
    A．he didn’t get along well with the librarian in the new school
    B．he was not allowed to work in the new school’s library
    C．he missed his old schoolmates and teachers

    The sun had gone behind a cloud. I was very tired and wanted nothing in the world so much as to be at home. At last I got to the gate of Hide Park. But this was worse than ever; there were buses there—high and terribly red cars, taxis and still more buses in an endless line. Everywhere there were people hurrying past or waiting to get into the buses, while I stood lost in the middle of them.
    I was ready to cry. In despair, I crossed the street on to an “island”, where I found a policeman. I took my last bit of courage in both hands and said, “Please, sir, where is Addison Road?” He began to explain, but when he saw that I couldn’t understand he became helpless, too. “Are you French at school?” A few minutes later, he smiled and raised his hand.

    In 1943, during the Second World War the body of an English man, William Martin, was discovered off the Spanish coast. The papers he had been carrying were returned to England, where they were carefully examined. They had clearly been changed and that was exactly what the British had hoped would happen, for Martin was a trick designed to fool the Germans.
    　 Martin did not exist. The body was that of a sailor who looked as though he had died when his boat sank, but in fact he had been ill and died. Leaving the boat to go down, his parents allowed the dead body to be put into the sea near Spain. It was hoped that the Germans would find it and read the fake(假的)papers he carried.
    　　The papers said that the British would attack the island of Sardinia, when in fact they planned to attack the island of Sicily. The trick was successful. When the British landed on Sicily, most of the heavy German guns had been moved to defend(保卫) Sardinia.
    小题1:______ put the papers on the dead man.
    A．The BritishB．German spiesC．Spanish soldiersD．William Martin
    小题2:When the Germans found William Martin they probably thought he _________.
    A．was a British spy with important information about the war
    B．was killed by the British soldiers
    C．died of an illness
    D．had the fake papers of the British Army
    小题3:When the British found out the papers were changed they concluded _________.
    A．Martin did existB．Martin was a German spy
    C．the Germans had read the papersD．they should attack Sardinia
    小题4:Which of the order is right according to this passage? __________.
    a. The Germans found the dead at sea.
    b. The British decided to use the dead body to fool the Germans.
    c. The British planned to attack Sicily.
    d. The papers on Martin were brought to London to be examined.
