常去理发店修面,对理发师刮胡子的一套程序习以为常,从来没有认真思考过。有一天,我问理发师为什么在给人刮胡子之前要涂上肥皂水,胡子刮完之后又要在脸上抹上一些润肤霜。理发师告诉我,涂肥皂水是为了刮起来不让顾客感到疼痛,抹润肤霜是为了使客人的皮肤得到滋润。我们时常把领导的批评戏称为“刮胡子”,由此又联想到教师对学生的批评教育。 I often go to the barber shop and practice a routine to shave the barber. I never thought about it. One day, I asked the barber why he had to apply soapy water before shaving his hair. After the beard was scraped, he had to apply some moisturizer on his face. The barber told me that the soapy water was used to shave away the pain of the customer. The moisturizer was used to moisturize the skin of the guests. We often refer to the leadership’s criticism as “shaves”, which in turn evoke the teacher’s criticism and education of students.
