[Su Jiaoban Textbook 8]
It was a sunny noon, and an apricot tree near the courtyard wall was faintly pink. Grandpa Zhu Kezhen came back from the outside and saw the apricot flowers, so he went to the apricot trees and counted them. Four flowers bloom in different programs. At this time, the owner of the apricot tree is coming with his children.
"Grandpa, are you looking at flowers again?" The child raised his face and asked innocently.
"Yes, the apricot blossoms are in bloom." Grandpa Zhu bent down and habitually asked, "Do you know when the apricot blossoms will bloom?"
"What day? It opened today. " The child is a little strange.
"I asked when the first apricot blossom would bloom," Grandpa Zhu added. The child couldn't answer, but he didn't understand why he needed to know when the first apricot flower would bloom. Grandpa Zhu told him: "I am useful, you should pay attention next year."
Time flies, another year in a blink of an eye. Spring breeze has blown green the willow tips, green grass, wrinkled the river and swelled the buds of apricot trees.
On this day, Grandpa Zhu was reading a book in his study when he suddenly heard a child's voice outside the window: "Grandpa Zhu! Grandpa! "
Who's shouting in such a hurry? He hurried out of the study and saw the child in the front yard.
"What is it?"
"Grandpa Zhu, the apricot blossoms are in bloom!"
"When?"
"Just now."
"Is it the first flower?"
"yes."
Grandpa Zhu seemed to be a few decades younger and rushed to the front yard at once. Apricot trees in the sun produced the first blooming apricot flower. What beautiful apricot flowers! Grandpa Zhu returned to his study, opened his notebook and solemnly wrote down this day: Tomb-Sweeping Day.
Grandpa Zhu Kezhen once said more than once, "What I need is accurate time. Words like' probably' and' possible' cannot be used in scientific research, and estimation and inference cannot be used instead of observation. " It is through years of accurate observation that Grandpa Zhu has mastered the law of climate change.
