Two hours passed quickly, and at the end of the tea party, Professor Yu Feng said: "I am also the chairman of the fitness committee of Hongyi Academy, and I myself like sports. I want to know, who of the students in your class has a special talent in sports?"

"Me!"

"Me, me!"

The students responded positively.

"Come one by one, Zhang Kai, which project are you good at?" Professor Yu asked.

"I can play basketball. Zhang Kai, who is 1.72 meters, said with confidence.

"You're playing point guard, right?" Professor Yu accurately measured Zhang Kai's height and asked, "Did you apply to join the school team?"

Zhang Kai: "Professor Yu is referring to the Jiangcheng University basketball team?"

"Yes. ”

"Not really. I used to be the main player of the first (10th) class of Zhumadian No. 1 Middle School, and I played from my freshman to my senior year, and I was able to play a number of positions on the court, such as small forward, scoring guard, and point guard. ”

"Zhang Kai, you kid is so funny. Professor Yu smiled dumbly, and his impression of Zhang Kai deepened a little.

"What about you, Yuan Lei, what project are you good at?" Professor Yu asked another student.

Yuan Lei was a little ashamed and said, "Uh...... I can play soccer and was the best eighth man in my class when I was in high school...... We play seven-a-side football. ”

"For the big ball project, students who were selected for the school team when they were in middle school should raise their hands. Professor Yu didn't ask one by one, and directly brushed it in groups.

No one raised their hand.

"Small balls?"

No one raised their hand.

"Racing?"

No one raised their hand...... Wait, Xia Lu raised his hand.

"Xia Lu, what is your specialty?" Professor Yu asked.

Xia Lu said: "I can swim, but our high school does not have a school swimming team, but my high school swimming teacher said that I swim well. ”

"Oh, what kind of swimming style are you good at, and what is your best grade?" Professor Yu became a little interested.

Xia Lu replied truthfully: "I know all four swimming styles, and the fastest time is the 50-meter freestyle, swimming for 28 seconds." ”

"That's good!" Professor Yu slapped his thigh, he looked quite excited: "Xia Lu, if you can really swim to 28 seconds in your 50 free, then it is no problem to participate in the school-wide sports meeting." ”

Jiangcheng University will hold a school-wide sports meeting at the end of October, and Professor Yu encourages everyone who can sign up to sign up, and the main purpose is to strengthen the body, and the focus is on participation.

Xia Lu reported a 50-meter freestyle, which was the single event he was most confident in.

It was the mule that the horse came out for a walk, and Yu Feng was also a swimming fan, so he called Shangxia Lu to go swimming together.

Jiangcheng University has a swimming pool, which is open-air. This outdoor pool is only open from July to August, and the Jiangcheng University swimming team rents the off-campus swimming pool for a long time.

Yu Feng and Xia Lu came to a competition-level swimming pool, and the two changed into swim trunks, swim caps, and goggles, and swam after warming up.

Professor Yu, who is in his thirties, is in good shape, which shows that he usually exercises regularly.

Xia Lu's figure is better, after all, he is young, less than twenty years old.

"Xia Lu, you swim 50 yourself, I'll time you. Yu Feng borrowed a block watch from the coach of the swimming pool, he is quite familiar with the coach here, and he is a supreme member of this swimming pool.

"Good. Xia Lu stood on the jumping platform and raised his arms to signal that he was ready to go.

Thump!

Xia Lu jumped into the water, and after a 15-meter dive, he entered the middle of the swim.

Xia Lu's freestyle movements are relatively standard, with powerful arms and strong legs.

Yu Feng on the shore looked at it and saw something unusual.

Non-professional swimmers swim 50 meters of freestyle, either on the left side or on the right side, and some people are on both sides.

For example, Yu Feng, he is used to ventilating on the left side.

Xia Lu did not breathe the whole time, he swam 50 meters in a breath and went directly to the side.

"Xia Luqiang!" Yu Feng was so surprised that he forgot to pinch his watch.

In the Olympic swimming competition or the World Swimming Championships, Yu Feng often sees professional male swimmers swimming the 50-meter freestyle without breathing, which can swim faster, of course, more tired.

A female swimmer who is relatively good can also do the 50-meter freestyle to the side in one breath.

However, among amateurs, it is rare to see Xia Lu in such a situation of going to the edge in one breath.

"Whoop...... "Whoa" Xia Lu grabbed the edge of the pool and gasped for breath, swimming 50 meters in one breath is an extremely strenuous anaerobic exercise, Xia Lu is so tired that he can't do it.

Professor Yu ...... How many seconds did I swim?" Xia Lu asked.

Professor Yu smiled: "I'm sorry, I'm sorry, I just admired your extraordinary swimming skills in one breath, and I forgot to pinch my watch." Xia Lu, you go ashore, let's rest for a while. ”

"I ...... You ......" Xia Lu was speechless, with his current level of physical fitness, he could only do a 50-meter freestyle without ventilation once in a few hours.

"I never expected that our Hongyi Academy would have a swimmer like you Xia Lu. Yu Feng was impressed by Xia Lu, he stretched out his arm and pulled the exhausted Xia Lu ashore.

The two teachers and students replenished water and minerals in the rest area, and Yu Feng kept complimenting Xia Lu's superb swimming skills, looking more like a swimming coach than a math professor.

"Xia Lu, your cardiopulmonary function and anti-lactic acid ability are stronger than ordinary people. "Yu Feng is quite professional, after all, he is an academic university professor, and he studies all walks of life with an academic attitude.

"So-so. Xia Lu told the truth, his physical function level is just an ordinary two-star, and he has an underwater breath-holding skill, which may be an important guarantee for him to be able to reach the side in one breath for 50 meters.

"Come on, Xia Lu, I'm very optimistic that you will get a place in the all-school sports meeting. As far as I know, none of the members of our school's swimming team can make it to the side in one breath at 50. ”

"Professor Yu, I think the assignment you assigned two days ago should be considered from the perspective of linearity and nonlinearity...... Leibniz's monadism is a typical Baroque non-linear thought...... I have studied it carefully, and Leibniz's monadism seems to predict quantum entanglement in a bizarre way...... I don't know if it's right, I'm not good at learning, please give me more advice......" Xia Lu used the time he spent alone with Professor Yu to talk about his views on Newton's thought and Leibniz's thought.

"Yes, Xia Lu, it's a little surprising to me that you can think to this extent in a few days. Yu Feng's eyes lit up and said, "Keep up the good work and keep it up." Let's talk about swimming, so you're a sprinter?"

"Sort of, I really can't swim in a single event above 200 meters...... Professor Yu, when it comes to Newton's classical thought, I personally think ......"

"Don't Newton, it's time to learn, it's time to play. If you can get a good ranking in the swimming competition, I will give you a perfect score for your usual math score. After the school-wide sports day, I'll take a moment to talk to you about Newton, Leibniz, and any other math that interests you. ”
