有位诗人曾说:“微笑是一种心灵的感应,微笑能化解所有忧愁,微笑能使人信心百倍。”的确,微笑是一种态度,一种理解,一种宽容。在顺境中,微笑是对成功的嘉奖。在逆境中,微笑是对创伤的理疗。而当教师当久了,严肃惯了,整天板着一副学究式的、长者的冷面孔,似乎忘记了微笑了,或者在学生面前不会笑了。可是我们的学生却无时不在期盼着老师的笑脸。 A poet once said: “Smile is a telepathy, a smile can resolve all sadness, smile can make people confident. ” Indeed, smile is an attitude, an understanding, a forgiving. In good times, smiling is a reward for success. In adversity, smiling is the treatment of trauma. When teachers are used for a long time, they are seriously used to it. They wear a learned, elder cold face all day long and seem to have forgotten to smile or smile in front of their students. However, our students are always looking forward to the teacher’s smile.
