真正的美食,在饱了口福和肠胃之后,还应该让人的内心得到慰藉。就连制作美食的过程也是如此,现在人们用煤气、天然气,总觉得烧出来的菜没有柴火锅烧出来的香。一个原因就是煤气关了,热量就停了,不像柴火熄了,柴灰还热着,这点慢悠悠的热度,恰能把食物蕴藏的美味烘出来。好课,也应该是有余味的。长期的课堂洗礼,让我深信不疑!有余味的课,对学生来说, Real food, after full of blessing and stomach, but also should make people feel comfort. Even the process of making food is also true, and now people use gas, natural gas, always feel that there is no burning out of the wood fired pot of incense. One reason is the gas off, the heat stopped, unlike the firewood out, the ash is still hot, this time leisurely heat, just delicious food baked out. Good class, it should be aftertaste. Long-term classroom baptism, I am convinced that there are aftertaste classes for students,
