What kind of difficulties will Newton encounter in making windmills? Tell me about it.

More than 200 years ago, there was a great scientist named Newton in England. Newton was born in a peasant family. When he was studying in primary school, he especially liked to do handicrafts. Grandma gives him pocket money, and he always saves it to buy saws, axes and chisels. He is busy doing handicrafts all day, and his academic performance is not very good.

One day, Newton came home from school and saw a windmill being installed next to the village. He stopped to look carefully and almost forgot to go home. Every day after school, he will go to see it for a while. After the windmill was installed, Newton helped grandma carry a bag of flour around the stone mill. Newton said, "Grandma, I want to be one when I go back."

Every day when he came home from school, Newton got into the room and was busy everywhere. A few days later, a small windmill was really made. With the fan, the windmill creaks. Grandma said, "Can your windmill grind noodles?" Newton naively said, "Yes!" Grandma smiled.

The next day at school, Newton put his little windmill on the table. The students all gathered around to watch. Newton turned the windmill proudly, and everyone praised him for doing well. Just then, classmate Carter said loudly, "Newton, why does the windmill turn?" Can you tell the truth? "

"Truth?" Newton never thought it reasonable to do manual work. Carter looked at Newton and said with a smile; "I can't be honest. What's so rare about doing this? How ridiculous! " The generated classmates also gave a burst of laughter. I don't know who pushed it, but the windmill fell to the ground and broke into pieces.

Newton blushed with shame. He picked up the broken windmill and felt terrible, but he did not shed a tear. From then on, Newton made a determined effort to ask why he met everything, and gradually developed the habit of studying hard.
