【简答题】
David came from a poor family. When he finished his high school, however, he was given a wonderful present. “Some of my friends got new clothes and a rich boy even got a new car,” he remembered, “My dad reached into his trousers pocket and took something out. I held out my hand, and his present dropped into it — a nickel (五分镍币).” Dad said to me, “Buy a newspaper with that. Read every word of it. Then turn to the classified section (分类栏目) and get yourself a job. Get into the world. It’s all yours now.” I always thought that was a great joke my father had played on me until a few years later when I was in the army, sitting in a foxhole (战壕), and thinking about my family and my life. It was then that I realized that my friends had got only new cars, or only new clothes. My father had given me the whole world. What a great present! 1. When David left school, he received ______ as a present. A. a new car        B. new clothes         C. a newspaper     D. hardly anything 2. What did David become a few years later? A. A college student.  B. A rich person.      C. A soldier.     D. A newspaper reporter. 3. The title of the passage may be ______. A. How to be a Soldier  B. How to find a Job    C. A Great Joke D. A Great Present
