Mr. Loewi was a geography professor. His teaching method marked a new epoch in education. His students welcomed him with enthusiasm. They often waited for him at the entrance of school. His best essay entitled him to win a national prize. Also he compiled a dictionary that had over 10,000 entries. He entitled the dictionary "Our environment" . Many people envied his good fortune. But he did believe in equality of opportunity. In fact, Mr. Loewi's most essential quality was kindness. He was in entire agreement with an opinion, that is, the equation of wealth with happiness could be dangerous.They were not equivalents. So he always was enthusiastic about helping others. Last summer, Mr.Loewi led his stu-dents to inspect a mountain at the equator. They prepared enough food. Though it is the computer era, the food is essential to life. Also they put some medicines against an influenza epidemic in an envelope. The entry to the mountain was behind lush trees. They erected their tents there. It was an erroneous choice. They ignored the erosion of the mountain by the volcanic ash! The mountain was different in essence with normal mountains. It was a volcano! The second morning, the volcanic erupted suddenly. To save one student, Mr. Lowei sacrificed his life. The students never could erase the episode from their memories.

　　洛伊先生是一名地理教授。他的教学方式标志了教育的新时代。他的学生怀着极大热情欢迎他。他们常常在学校的入口处等他。他的最佳文章使他有资格获得国家奖。他还编著了一本超过一万个条目的字典。他给字典题名为“我们的环境”。许多人忌妒他的好运气。但他只相信机会的平等。实际上，洛伊先生最基本的品质是善良。他完全同意一个观点，即把金钱同快乐相等起来是很危险的。它们不是等价物。于是他总是热心帮助别人。去年夏天，洛伊先生带他的学生去考察位于赤道的一座山峰。他们准备了足够的食物。虽然是计算机时代，食品还是生命里不可缺少的。他们还在一个信封里放了一些防止一种流行性感冒的药品。山的入口在浓密的树丛后面。他们在那里竖立起帐篷。这是一个错误的选择。他们忽视了山体被火山灰腐蚀的迹象!这座山在本质上同普通的山不同。它是座火山!第二天早上，火山突然爆发了。为救一名学生，洛伊先生牺牲了自己的性命。学生们永远也不会将这一片断从他们的记忆中擦掉。
