Which of the following is true according to the passage?

参考解析：

推理判断题。根据文章第一段第一句“My elder brother Steve gave me important lessons in values that helped me grow into an adult after my father died when I was six years old”可知，我哥哥史蒂夫给了我很有价值的经验帮助我成长为一个成年人，因此，作者写这篇文章时已是成年人，所以A选项是错误的；根据文章第四段倒数第二句“Even if it hurts you first, you should think a long time and then decide whether you will kill it or not”可知，即使它先伤害了你，你也应该考虑很长时间再决定是否杀了它，因此，即使一个小生物伤害了你，你也不应该立刻杀了它，所以B选项是错误的、D选项是正确的；根据文章第三段第四句“He also reminded me of how sad I was when I lost the small wooden dog my father made”可知，他也提醒我当我丢了爸爸用几块小木头给我制成的小狗时，我是多么的伤心，因此，我丢的小狗是爸爸用木头做的，所以C选项是错误的。故选D。
