After Zhuge Liang came to Shuijing Villa, Ma Hong's life was not very easy. A few days ago, Zhuge Liang found the Spring Palace map under Ma Hong's pillow, which made Ma Hong lose face, but fortunately, Zhuge Liang is not a big mouth and will not publicize Ma Hong's glorious deeds everywhere. But Ma Hong is now guarding against Zhuge Liang like a thief, it turns out that Ma Hong never locks the door when he goes out during the day, and he never closes the door at night. Now Ma Hong pulls the latch every night before going to bed, and puts two three-reed locks on the door when he goes out during the day. [In the Han Dynasty, copper reed structure locks, commonly known as three-reed locks or reed locks, used the elastic force of two or three plate-like copper sheets to achieve the effect of sealing and opening. 】

By the small pond, Ma Hong wears a straw hat made of water weed, sits on his handmade chair, and sits under the willow tree with a long bamboo pole in his right hand. Suddenly, a loud singing voice came to my ears: "The leaves are pale, and the white dew is frost." The so-called Iraqi people are on the water side. Tracing back to it, the road is obstructive and long. Tracing from it, it is like being in the middle of the water. ”

Ma Hong rubbed his head helplessly and looked at Zhuge Liang who walked towards him, in Ma Hong's words, Zhuge Liang is dressed quite fashionably today, carrying a bamboo basket in his left hand, holding a bamboo pole in his right hand, a long straw rope wrapped around his waist, and wearing straw sandals on his feet and looking at Ma Hong with a smile. Ma Hong rubbed his head and shouted in his heart: This is definitely not the Zhuge Prime Minister in my heart, how can this be the Prime Minister who has done his best and died, this is clearly a comic.

"Did the fish take the bait?" Zhuge Liang walked up to Ma Hong and asked.

"Nope." Ma Hong replied very simply.

Zhuge Liang shook his head and said, "Fortunately, I am prepared, otherwise there would be no fish for dinner." ”

After Zhuge Liang finished speaking, he bent down and put down the bamboo basket, untied the long straw rope from his waist, tied one end to the bamboo basket, and tied the other end to his bamboo pole, and then found two small stones and put them into the bamboo orchid, and then threw the leftover oil cake from the noon into the bamboo basket, and then put the bamboo basket into the pond, and finally patted his ass and sat next to Ma Hong.

"With such a big land, why are you sitting next to me, junior brother?" Ma Hong asked.

"I catch small fish, watch you catch big fish."

"You sit next to me, I can't catch any fish."

"That proves that you are not skilled, and I can teach you how to fish by the way."

"Senior brother, forget it, I can study it slowly."

"Well, that's fine, we can discuss something while we're free."

"Don't interfere with my fishing."

"Ma Hong, look, I'm two years older than you, it's a little inappropriate for you to always call me junior brother, right! Why don't we two change it, in the future, you call me senior brother, and I call you junior brother, okay? ”

Ma Hong smiled at Zhuge Liang, Zhuge Liang also smiled back, and then Ma Hong pouted: "No way, there is a sequence of hearing the Tao, I apprenticed earlier than you, I am your senior brother, and even Yang Yi, who is younger than you, is also your senior brother." ”

Zhuge Liang smiled and said, "Yang Yi has called me senior brother now." ”

"When?"

"Two hours ago."

"Why?"

"I promised him that with me in the future, his sheep would never be lost. If he doesn't agree, I'll steal a sheep from him every day. ”

"So spineless, how are you going to threaten me?"

"Ma Hong, you are joking, how could I threaten you, at most I will take out the picture of the Spring Palace you drew and share it with the villagers, if it reaches the teacher's ears, the teacher will probably not be able to help but look at it, good things to share with everyone and not beautiful."

Zhuge Liang's sentence is not beautiful, which reminds Ma Hong of Wang Situ (Wang Lang, the specific reason is known) in the Romance of the Three Kingdoms, although he was threatened by Zhuge Liang, Ma Hong still said casually: "Even if I agree, the teacher will not agree, after all, there is a first-come, first-served." ”

"I've already said it to the teacher, and he said that we can make our own decisions about these things."

Zhuge Liang blinked, the sun darting on his long eyelashes, and he looked at Ma Hong.

Ma Hong tried not to look at Zhuge Liang's eyes, and was bewitched by his eyes, but he just smiled, patted Zhuge Liang's shoulder and said seriously: "Senior Brother Zhuge , you can not call me Senior Brother, but don't worry, I will definitely call you Senior Brother." ”

Zhuge Liang saw that Ma Hong didn't agree no matter what, so he used the agitation method to say: "Ma Hong, last time I wanted to compare with you, because there was no comparison because of the time problem, today we might as well have a competition, if I win, you will be my junior brother in the future, if you win, you will be my senior brother in the future." ”

Ma Hong secretly said in his heart: Why is Zhuge Liang so difficult, do you have to compare with me? Are you forcing me to hang up? Do you have to let me defeat you with the crystallization of 5,000 years of wisdom from top to bottom of China? Although I don't want to cover you with Tang poems and Song lyrics, it looks a little stinky and shameless, but well, you forced me.

Ma Hong was about to open his mouth to fight, and suddenly thought of a question, why did he write "Peach Blossom Fu" last year, because poetry has not yet prevailed in this era, and poetry is difficult to get into the elegant hall, Fu is the mainstream, and Fu In addition to the "Peach Blossom Fu" that he wrote himself, he will also recite two sentences of "Luo Shen Fu", and he also knows "Goddess Fu". It's just that "The Goddess Fu" has come out, and Cao Zhi should still be a little kid now, but Ma Hong can only say two sentences, and he can't take them out.

Zhuge Liang saw that Ma Hong had been silent, so he picked up a small stone on the ground and said with a smile while playing with it in his hand: "What? Do you want to reject me one more time? If you admit defeat, I'll call you junior brother in the future. ”

Ma Hong secretly said in his heart: If I retreat without a fight, Zhuge Liang will inevitably look down on me, I have to frustrate his sharpness, but I am also a traverser, and I have thousands of years of knowledge more than him.

"Okay, I'll fight." Ma Hong said.

"Not bad, good, backbone, what do you want to compare?" Zhuge Liang said with a smile.

"How is it better than arithmetic?" Ma Hong said.

"Oh! Brother, aren't you better at articles than you? The surprise in Zhuge Liang's eyes flashed, and then his eyes glowed with a strange color, obviously Ma Hong wanted to compare arithmetic with him, which aroused his interest.

Ma Hong put down the fishing rod, took a branch and nodded it on the ground, and said, "I'll give you an arithmetic problem, if you can calculate it in half an hour, I will admit defeat." ”

Zhuge Liang smiled and said, "A word is a certainty." ”

Than arithmetic? The smile on the corner of Zhuge Liang's mouth made him look more confident, since he was twelve years old, there were no arithmetic problems that Zhuge Liang couldn't solve.

Ma Hong saw that Zhuge Liang was so confident, and said with a smile in his heart: Zhuge Liang, even if you are extremely smart, but you don't have the knowledge of my era, I don't believe that you can solve the college entrance examination questions of my era. Forget it, I don't embarrass you, just give you a very simple acceleration problem in physics!

Zhuge Liang stretched out his hand and straightened his hair, then sat upright in a proper manner, stretched out his hand and said, "Please ask the question." ”

Ma Hong smiled slightly, picked up a branch and drew a straight line on the ground, and then marked A and B at both ends of the straight line, and then found a point on the straight line and marked C. Then he said: "Now suppose Zhuge Liang and Pang Tong each lead an army, Zhuge Liang is in City A, Pang Tong is in City B, and there is a City C between City A and B. The general of Bingcheng's unified army is Yang Yi, and Yang Yi is Zhuge Liang's subordinate. The two cities A and C are 90 miles apart, and the two cities are 160 miles apart. Now Pang Tong led the army from City A to march at a speed of 30 miles per hour towards City C, and Zhuge Liang led the army from City B to support. In order to save Yang Yi, Zhuge Liang adopted the method of rapid marching to speed up the march to Ccheng. Its initial marching speed is 20 miles per hour, and its acceleration thereafter is 8 miles per hour. May I ask? 1. How long did it take Zhuge Liang to lead the army to Bingcheng? 2. When Zhuge Liang led the army to Bingcheng, what was the marching speed of the soldiers? ”

Zhuge Liang smiled slightly: "It doesn't sound difficult. ”

Ma Hong smiled slightly and did not speak, but secretly said in his heart: This is a one-dimensional quadratic root equation, you don't know the root finding formula, how can you calculate it, I see how you make it up. ”

Zhuge Liang thought seriously for a while and asked Ma Hong: "Does this acceleration mean that the speed of the march changes from moment to moment?" ”

Ma Hong nodded and said, "Exactly, at the beginning, the soldiers' marching speed was 20 li per hour, and at the end of the first hour, their marching speed reached 28 li per hour, but in the first hour, their speed was increasing. ”

Zhuge Liang said: "Did you give Pang Tong's marching speed to confuse me?" Simply useless. ”

Ma Hong smiled silently.
