The next day was Saturday, and in the afternoon, Kejing asked her female classmates to go out to play, and Li Keding was bored at home alone, so he stepped out and wandered around, but unconsciously walked along the road to school. After turning two alleys, I saw several large carts driven out of a courtyard in succession, loaded with furniture for use. I thought to myself who this was, but there were a lot of things. When I got closer, I turned my head to look at the door number of the gatehouse, and was surprised to find that this was not the girl in red's house? Dark Dao: I don't go to school today, why did I take this path? I wanted to go back, but my feet lingered in the same place. Take a few laps back and forth and simply wander around here. Because he had nothing to do, thinking of the physics question Ke Jing asked him yesterday, he was purely looking for something for himself, and he was pacing while meditating at the gate of the house.

The so-called thousands of miles of fate to meet, just when Li Keding was thinking, a foreign car stopped in front of him, interrupting his thoughts. Li Keding raised his eyes and looked at it, he couldn't help but be surprised, it really didn't take any effort to come here, it was the girl in red who was sitting in the car, but she was wearing yellow clothes today. This time he was face to face with the girl, and he was very close, Li Keding saw the girl's appearance very clearly, and immediately shocked her beauty, and said in her heart: Could it be that I have dazzled my eyes, how can there be such a woman in the world?

The girl got out of the car, her posture was graceful, and she was about to enter the door, Li Keding really wanted to meet her, and she couldn't bear to miss the opportunity, so she was ruthless, cheekily stepped forward and said, "This young lady, slow down!" The girl looked back at him, wondering who was talking to him. asked Li Keding: "Is there anything wrong?" Li Keding suddenly had a flash of inspiration and had an idea: "Oh, I heard that Miss is studying in Tiren Middle School, and there is just a physics problem, I have been thinking about it for a few days, and I haven't figured it out. The girl smiled slightly and said, "Don't you dare to teach, you say, what's the problem?" ”

Her smile is sweet and beautiful, like spring flowers blooming, like a cool breeze in summer; The sound is like a warbler crying, like the sound of a piano around the beam, Li Keding's soul is snatched for it in an instant, and his heart is crisp, but fortunately, he has been thinking about the physics problem just now, so he said the problem clearly in three words.

After hearing this, the girl bowed her head slightly, looked at Li Keding with a smile and said, "This question is a bit interesting, but it is not difficult." ”

"Oh, please Miss for advice, I appreciate it." Li Keding hugged his fists.

"Don't dare to be. I'll try to answer it, and you'll see if it's appropriate. The girl's lips were lightly opened, and although her voice was low, it was extremely clear, so that people could hear it, as if in the ear, straight into the brain, and what she heard said: "The big wheel and the small wheel can be regarded as two concentric circles, and they roll each time, and the circumference is different, so the distance traveled by the roll must be different." However, the distance they move is the same, because the small wheel not only rolls with the big wheel, but the small wheel is still being carried by the big wheel. ”

Li Keding still didn't understand very much, thinking that this girl looked like she was only thirteen or fourteen years old, and she should not be in middle school for a short time, so she might not answer accurately, and she was suspicious. But the girl saw it, and only heard her say, "Do you doubt that what I said is wrong?" Let me tell you, more than 2,000 years ago, there was a philosopher in ancient Greece called Aristotle, and this question was raised by him, and it was proved by Galileo. The answer I just gave was also given by these sages, so you can believe it this time. ”

The girl's words are round and jade, Li Keding is like hearing the sound of Lun, like listening to witty words, is intoxicated, suddenly heard someone singing, when looking sideways, an old man who looks like a beggar, with a dirty face, holding a broken wine jug in his hand, drunk and confused, swaying is singing songs from the side.

Don't look at the old man's appearance, his singing voice is melodious, and he sings: 'At first glance, I saw the national color and heavenly fragrance, at first glance I saw the crazy young man, and at first glance, I saw the jade beauty on the water side. Only I know how to be careful, only I don't cry, I don't laugh, I don't exaggerate, what I say is that love and hatred are determined, and what I say is that the world is hot and cold. Ask the prince and the general, who cares about the emperor regardless of the fame; Ask Shinong Industry and Commerce, jump out of the life and death who cares about him Hades. In this world, I have no merit, no name, no life and death, I don't envy the gods and envy the mandarin ducks, I love the red makeup, and I am more comfortable than the sky. ’

Li Keding and the girl listened carefully to the old man's singing, and they both felt as if they were singing about the two of them, and the girl was only amused in her heart. Li Keding was about to go up to ask the old man, when he saw someone coming out of the gate, and said to the girl, "Miss, you are back, and the adults are waiting for you to pass." Hearing this, Li Keding hurriedly stood up and looked at the girl intently. The girl walked slowly into the door, looked back at Li Keding, her eyes were as happy as shyness, and she smiled again before turning around.

really looked back and smiled, Li Keding was stunned, just stood in place, and forgot the old man who had just sung to the clouds, for a while, only to see that the door was closed, and there was no trace of the girl, so he had to walk home.
