以下是我亲眼所见的两件小事。第一件,老师让学生去提水(原意是自来水)。出人意料的是,学生把热水灌入塑料桶,结果是塑料桶又软又热,无法提起。另一件事是一个学生为老师办公室送水。暖瓶在桌子上,他便把热水桶举到人头高,艰难又危险地把水灌入暖水瓶。老师告诉他把暖瓶拿下来 Here are the two small things that I have seen with my own eyes. The first time, the teacher asked the students to pick up the water (intended to be tap water). Surprisingly, students poured hot water into the plastic bucket.

He lifted the hot water tank to the top of the head and poured the water into the thermos bottle in a difficult and dangerous way. The teacher told him to take the thermos off
