不论黑板＋粉笔，还是粉笔＋黑板，我知道，它们的结晶都是爱，爱，爱！
No matter blackboard + chalk, or chalk + blackboard, I know that their crystallization is love, love, love!

春天来了，满园的桃花、梨花、李花都散发着清香，是甜？是快乐？而改革的春风已吹遍了千家万户，人们不再吃大锅饭了，农民不再受穷了。
Spring is coming. Peach, pear and plum flowers are fragrant. Is it sweet? Is it happiness? And the spring breeze of reform has blown through thousands of families, people no longer eat the pot, farmers no longer suffer poverty.
老子是一所乡村小学的教师。
Laozi is a teacher in a rural primary school.
在课上，他总是把自己心中的"墨水"都吐给学生。他告诉学生：黑板是公用的，你们有什么想写想画就写吧、画吧。
In class, he always spits out the & quot; ink & quot; in his heart to the students. He told the students: the blackboard is public. If you want to write or draw, please write or draw.
同学们都知道，老师是把自己比喻成黑板，把他们比喻成粉笔。老师希望同学们有疑问就去问老师。
The students all know that the teacher compares himself to a blackboard and them to chalk. The teacher wants the students to ask the teacher if they have any questions.
在那时，教学总是以老师为主，学生总是乐意接受老师传授的知识。
At that time, teaching was always dominated by teachers, and students were always willing to accept the knowledge imparted by teachers.
没有黑板，哪有粉笔？
Where is chalk without a blackboard?

在一个新的世纪里，科学教育已不再落伍，而这教育把重压寄托给学生。
In a new century, science education is no longer out of date, and this education places a heavy burden on students.
儿子在一所乡村学校教书。
My son teaches in a rural school.
在课上，老师坐在椅子上，让同学们自由讨论，让同学们发挥想象的空间，老师则在一旁作引导。
In the class, the teacher sits on the chair, lets the students discuss freely, lets the students play the imaginary space, the teacher makes the guidance in the side.
教学上，儿子总是视学生为上帝，他则是"上帝"的仆人。
In teaching, the son always regards the students as God, and he is the servant of & quot; God & quot.
儿子告诉同学们：他自己起引导作用，你们有什么疑问要互相讨论，到实实在在想不出来的份上，再来找我。
My son told the students: he plays a leading role. If you have any questions, you need to discuss with each other. Come to me for the sake that you really can't think of.
他说粉笔是有限，是用钱买的，不到万不得已的时候，不能在黑板上乱塗乱画。
He said that chalk is limited and is bought with money, and cannot scribble on the blackboard until the last resort.
同学们也明白：老师是黑板，粉笔是他们自己。
Students also understand: the teacher is the blackboard, chalk is their own.
后记：
Postscript:
星光下，老子和儿子坐在一起。他们各自谈论自己的教学。他们最后的共同语言是：
Under the stars, Laozi and his son sat together. They each talk about their own teaching. Their last common language is:
不论黑板＋粉笔，还是粉笔＋黑板，我知道，它们的结晶都是爱，爱，爱！
No matter blackboard + chalk, or chalk + blackboard, I know that their crystallization is love, love, love!
黑板＋粉笔＝粉笔＋黑板＝爱
Blackboard + chalk = chalk + blackboard = love
。
