小时候,我的学习成绩差,感到很自卑。一天,父亲指着房前一棵结满果实的树问我:“这棵树有用吗?”“当然有用,因为它能给我们提供果实。”我说。“所以,对于一棵树来说,所谓有用,就是因为它对别人有用。”父亲说。接着,父亲又指着一棵不能结果的树问我同样的问题。“当然就没用了,因为它不能给我们提供果实。”我说。“这棵树虽然不能给我们提供果实,但它长大后,可以做家具、做房屋的栋梁,即使做不成家具和栋梁,它还可以做柴 When I was young, my poor academic performance, I feel very inferior. One day, my father pointed at a tree full of fruit in front of the house and asked me: ”Is this tree useful?“ ”Of course it works, because it gives us fruit.“ I said. ”So, for a tree, the so-called useful, because it is useful to others. “ Father said. Then, my father pointed to a tree that failed to ask me the same question. ”Of course it’s useless because it does not give us fruit." I said.
