“同学们,老师首先请你们想象一下:有这么一棵树,挺立于大地,她要不断地长粗长高,成长为参天大树,在高高的天空撑起浓阴如云的华盖,她应该怎么做?”我一走上讲台,微笑地对学生们如是说。同学们感到有点意外,并没有马上回答我的问题。但彼此间一番低语后,就很快安静下来了,几十双明亮的眼睛,惊奇地看着我。在课堂上,我依然微笑地对学生们说:“那她的万千根须则必须要深深地扎进肥沃的土壤,那她的万千枝条则必须经过和风的爱抚。这一棵树,在温暖的和风爱抚下萌发出成千上万粒针尖般的芽苞,在灿烂的阳光照射下舒张出成千上万片绿叶。哦, ”My classmates, the teacher first asks you to imagine: There is such a tree standing upright on the earth. She wants to grow in length and height, grow into a towering tree, and lift up the overcast sky in the high sky. What should she do?“I walked onto the podium and smiled at the students. The students felt a bit surprised and did not immediately answer my question. But after whispering to each other, they quickly calmed down. Dozens of bright eyes looked at me in surprise. In class, I still said to the students with a smile: ”The herd must be deeply rooted in the fertile soil. Then her thousands of branches must be caressed by the wind. The tree sprouts thousands of needle-like buds under the warm wind and caress, and relaxes thousands of green leaves under the bright sunshine.
