2007年3月中旬,惊闻一个消息,初中的语文林老师被确诊为肺癌,一个很难接受的事实,从来没有想过这种事情会发生在身边的人身上。林老师五十多岁,头发短短的,身体微胖,总是笑眯眯的。她怎么会得肺癌呢?医生说:作为一名教师除了劳累外,最主要原因是长期“吃”粉笔灰,造成毒素在体内沉积。我的心情更加沉重了,不断地回想以前与老师相处的点点滴滴。在此我呼吁所有学校改变师生的教学与学习环境!我把老师得病的消息告诉了初中同学, In mid-March 2007, I was shocked to hear that a junior high school teacher named Lin was diagnosed with lung cancer. It was a difficult fact to accept. I never thought that this kind of thing would happen to people around me. Ms. Lin was in her fifties. Her hair was short and her body was fat. She was always smiling. How can she get lung cancer? The doctor said: As a teacher, in addition to fatigue, the main reason is the long-term “eat” chalk dust, causing toxins deposited in the body. My mood was even heavier, and I constantly recalled how I used to get along with my teacher. I hereby urge all schools to change the teaching and learning environment for teachers and students! I told my junior high school students the news that my teacher was ill.
