答案：
(答案→)B
解析：本文讲述了一位小孩和同学打架了而去找爷爷诉苦，他爷爷开导他的故事。
【小题1】根据下文中The grandfather said,可知，上文中一定会提到他的爷爷，选项中只有B，所以本题选B。
【小题2】根据It doesn’t hurt（伤害） your enemy (敌人) but only hurt yourself. 可知，本句应该是解释后面这句的。所以本题选C。
【小题3】根据前一句是说好老虎，而后面一句是不好的老虎，本句应该是说坏老虎的。故应该选A。
【小题4】通过后面一句They both try to control (控制)me可知，和两只老虎相处是很难的。所以本题选E。
【小题5】根据I always feed the good and kind tiger可知，本句应该选D。
