陈老师是上海市某重点中学的数学老师。五年前由于严重的哮喘,他不得不离开心爱的教学岗位。五年后的今天,令陈老师兴奋不已的是,一种新型环保水性粉笔使他摆脱了“粉笔灰”的困扰,他再也不必担心教室里飞舞的白色粉末,他重新回到了学生们中间,登上阔别已久的讲台。 有陈老师这样经历的教师并非少数。曾几何时,人们把当教师等同于“吸粉笔灰”,提起教师人们想到的也是“满身白粉”的形象。因此,环保水性粉笔的投入使用,让广大师生告别了“吸粉笔灰”的历史,是切实改善教学环境的一个里程碑。
Chen is a key middle school math teacher in Shanghai. He had to leave his beloved teaching position five years ago due to severe asthma. Today, five years later, to make Chen excited, a new eco-friendly water-based chalk relieved him of “chalk dust”. He no longer had to worry about the white powder flying in the classroom. He returned to the middle of the students , Boarded the long-awaited podium. There are not many teachers who have this experience with Professor Chen. Once upon a time, people equated teachers as “dust-pollinators” and brought up the image of teachers who also thought of “white powder.” Therefore, putting into operation the environmentally-friendly water-based chalk enables the majority of teachers and students to bid farewell to the history of “dust-absorbing chalk” and is a milestone in effectively improving the teaching environment.
