1.A 2.B 3.C 【解析】 【原文】 M: My father had always said it was because I was lazy. My brother said it was because my head was too heavy. My mother blamed my bad performance in school on my ancestors. As for me, I believed I was unlucky. In the eighth grade, for example, I was good at math. That’s why I liked video games — technical ones that you have to think about. Well, I stayed up late one night to finish a game that had taken me weeks to beat. In my enthusiasm, I had forgotten that there was a big math test the next day. Well, I won the game but failed the test. In the ninth grade, I started to become popular. Having so many friends meant less time for studying. But after I almost failed the 10th grade completely, I finally decided I needed to change something. I wanted the chance to go to college. That summer, I asked my parents to hire a private tutor. My parents were surprised because they had gotten used to disappointment. Of course, my brother just made fun of me as usual. He made me more determined to change. During the 11th grade, I exchanged my interest in video games for the enthusiasm for computer programming. The more I learned, the more I wanted to know. Because of the dramatic change I went through, I was even accepted into MIT. I changed my luck for good.
