My brother set a good example for me.

　　题干大意：我哥哥给我树立了一个好榜样。定位到文中第五段的第二、三句，“I had learned an important lesson--a lesson no one could have taught me with words. If I work hard for what I want, and if I keep trying after I've been turned down, my dreams can also come true.”，我从我哥哥身上学到了重要的一课——一个没有人能通用语言教会我的课。如果我为我想要的努力争取，即使在被拒绝后仍继续努力争取，我的梦想也会实现。题目与原文意思相符，故选A。
