my scientific age

Chapter 4 I Believe In You
The set questions are much simpler, which is to test the understanding and basic definition of sets, plus some questions of ordinary difficulty.

After Yu Hua finished watching Yile, it was not difficult, even felt simple.

Continuing to look down, the type of geometry consists of three-dimensional and two-dimensional. Start with planes, and the difficulty gradually increases. When you reach the level of three-dimensional geometry, the difficulty of the questions is approximately equal to the third-year-high-one interval in later generations.

Still not difficult.

As for the simplest trigonometry type of topics in high school mathematics, this is one of Yu Hua's few good projects. A rough reading is basically the same as the content of modern Huaxia high school mathematics, such as power reduction formula, double angle conversion, induction formula, sine theorem, Cosine formula, etc.

After flipping through the math textbook, Yu Hua was surprised to find that the difficulty of this thing is really not high. In the future, he will understand the level of math scumbags. Even a slightly complicated topic can be understood with a little thought.

Darling, is this the power of modern educational questioning tactics?

Even the math scumbag himself can crush the high school students of this era at the math level.

To be honest, compared to the various math problems that torture the nerves and brain in later generations, the mathematics level of today's high school in the Republic of China has temporarily stayed at the ordinary level, and the difficulty is only one-third of the later generations, which is really not difficult.

Although reducing the difficulty of mathematics subjects is meaningless for doing science, it at least improves the chances of getting admitted to National Tsing Hua University.

I have to say, it was a little surprise.

After simply flipping through the textbook, after browsing the general content and table of contents, Yu Hua, who fully understood the situation, did not have any arrogance in his heart. He went back to the beginning again, turned to the collection of Mathematics Chapter 1, and started to chew from the most basic.

A thousand miles begins with a single step.

Now, lay the foundation.

Holding the mathematics textbook published in 1934, as a math scumbag, Yu Hua had a headache for mathematics, which was mainly based on abstract logic.

The brain responds quickly, and the memory effect is excellent. When encountering doubts and incomprehensions, the content of the later high school math teachers can emerge in the mind, combined with formulas, find clues, and solve them.

Gradually, Yu Hua entered a state of ecstasy, highly concentrated, nothing around him disappeared, there was no sound in his ears, only him and the book remained.

The collection of Chapter 1 is quickly read, the functions of Chapter 2 are easy to understand, and the algebra of Chapter 3 is simple...

Immersed in it, Yu Hua, who continued to solve problems, became more and more interesting, and the more he read, the more he could understand the mystery. For the first time, he felt that solving mathematical problems can make people happy, not painful.

As time passed, the sky gradually began to snow.

"Dong - dong, dong, dong!" I don't know how long it took, at this moment, in Jinguo Hutong, a loud and distant metal knocking sound came out, one slow and three fast.

The sound comes from the gong, indicating that the hour has come.

After the four gongs were beaten, in the wind and snow, the beating man slowly walked away.

"I actually read the book for so long."

Hearing the sound of the gong, Yu Hua, who was in a state of ecstasy, suddenly came to his senses, his mind felt exhausted, and he looked at the notebook on the table, which was densely covered with the handwriting of the subject calculation content, and then looked at the content of the textbook. Raising the watch, there is some surprise and surprise.

At twelve thirty, inadvertently, more than four hours have passed.

Strange, what's going on here?
My little elementary school scum actually watched mathematics for so long at one time. The point is, I still read it with relish.

In the past 18 years, Yu Hua has never studied mathematics for more than an hour, at most five or ten minutes. In high school, he became dizzy after two, three and ten minutes. Books, big eyes and small eyes, no one knows anyone.

Now I actually gnawed it for more than four hours at a time, and gnawed it with relish, which made Yu Hua feel extremely surprised. Could it be that the soul of a schoolmaster hidden in my body for 18 years is about to wake up?

Look down.

Looking at the book, Yu Hua frowned slightly, and suddenly felt that the knowledge was obscure, abstract and boring, and the knowledge that was not very difficult became difficult at this moment, and the whole person tried to find the state just now.

1 minutes.

2 minutes.

5 minutes.

10 minutes.

"Hey……"

Facing the math book like a book from heaven, Yu Hua, who had been unable to enter the state for a long time, sighed and gave up.

Sure enough, a scumbag is a scumbag, the soul of a scholar with a hammer.

"Maybe it's been watching for too long, or it may be because of his predecessor. He prefers to read mathematics, and he should have some talent in this regard. I got some light."

Yu Hua sighed, rubbed his swollen temples with his hands, and thought about the reason for a moment, only to feel his head dizzy and his body still a little cold, knowing that this was a warning from his body: "Huh, I will see here for the time being today, tomorrow continue."

No longer demanding, learning pays attention to efficiency, and requires a combination of work and rest.

I have been studying since I traveled over, and it is time to rest.

Close the book gently and put it away.

After turning off the expensive lights, Yu Hua, who was exhausted, took a plastic basin, toothbrush and toothpaste, poured some hot water, and after washing, he lay comfortably on the bed.

As soon as his body touched the bed, he involuntarily let out a comfortable moan from all over his body, relaxing as much as possible, Yu Hua covered the quilt and quickly fell asleep.

……

This is a gray and dead world, surrounded by ruins, buildings collapsed, and not far away there is a spectacular gatehouse that is dilapidated as if it was bombarded by shells, with three big characters standing at the top - the Presidential Palace.

In the haze, Yu Hua felt that he had come to the bottom of the gate of the Presidential Palace.

This is?

Just when Yu Hua was confused, suddenly, a hand full of blood rested on Yu Hua's shoulder.

Yu Hua was startled and turned around abruptly. A Kuomintang soldier wearing a German helmet with blood on his face came into view. He was carrying a medium-sized rifle, his chest was full of bullet holes, his clothes were tattered, and he looked at Yu Hua with a pair of eyes. .

"I believe in you." After a second, there was a hint of color in the eyes of the Kuomintang soldiers, which was trust and hope, and said softly towards Yu Hua.

"What do you believe in me?" Yu Hua was a little confused.

The Kuomintang soldier with blood on his face smiled: "I believe in you."

"I believe in you." At this moment, another slender and fair hand was placed on Yu Hua's shoulder, and he turned his head. It was a girl in blue girls' clothes. There was a sharp blade, she showed a graceful and elegant smile, and said softly.

Immediately afterwards, a small hand grabbed Yu Hua's right hand and looked down to see a girl covered in blood standing there. She looked up at Yu Hua, her big eyes showing longing and hope: "I believe in you."

The voice is crisp and full of childishness.

"I believe you……"

Different arms touched Yu Hua's shoulders, and more and more people appeared covered in blood and wounds. There were Nationalist soldiers shot in the chest, Red Party soldiers wearing straw sandals, and young and beautiful adult women. There are unpretentious rural women and strong rural men.

The number of people is increasing, and looking around, it is already dense and endless.

Everyone had a smile on their faces, stared at Yu Hua, and said these words softly and firmly. The scene that was supposed to be weird and horrifying made Yu Hua want to cry.

I believe you.

I believe you.

I believe you.

This is a cry, a hope.

Yu Hua fell into silence. He stood there in a daze, looking at the bloody Kuomintang soldiers, at the graceful Republic of China girls, at the immature girls, and at the crowd gradually emerging behind him, he suddenly understood, understood The 'belief' they said was something, and the corners of their eyes were rosy and sparkling.

These are the people who died in the Anti-Japanese War.

"I will not betray your trust, absolutely not." Yu Hua, who already knew what he should do, tried to control his emotions, and said firmly and solemnly.

"I believe in you." As if hearing Yu Hua's answer, the young girl nodded lightly, and the smile on her face seemed to be more prosperous.

trust.

This is the trust of our compatriots, the trust of 3000 million people.

The words fell, with a smile, the figure of the young girl gradually disappeared, the bloody faces of the Kuomintang soldier and the little girl, and countless people around disappeared, leaving behind the ruined presidential palace gatehouse, everything returned to its original state.

After a while, the whole world gradually dissipated without a trace.

Outside, Yu Hua, who was sleeping on the bed, only felt that he had a very real dream. Tears flowed out of the corners of his eyes, slid over the skin, and flowed to the sheets. He felt hot all over, and he couldn't help kicking the quilt.

……

The next day.

New Year's Eve is over, the first day of the first lunar month.

A ray of sunshine broke through the clouds, driving away the gloom of many days.

Today is a rare good weather.

The new year has a new atmosphere, and the city of Peiping is filled with festivity. People take to the streets to say hello to each other, hoping that the new year will be a good year and a stable life.

Those who do business wear hats, walk around the streets with their burdens on their backs, and those who buy things and breakfast are shouting and selling, and the city is already lively.

In Chongwen's house, Yu Hua caught a cold.

"Ah... embarrassing!"

He sneezed fiercely, and a lot of saliva flew around. Yu Hua, who was sitting beside the bed, had a runny nose, wiped the turbid liquid with his hands, then lifted the kettle and poured half a bowl of ginger soup into the porcelain bowl on the bedside table. , took a sip to drive away the cold and generate heat.

I don't know if it was due to the wind blowing last night, the temperature was too low, or the bedding was kicked up. Yu Hua woke up this morning, feeling top-heavy and uncomfortable, with a red, swollen, runny nose, typical symptoms of a cold and fever.

Today's plan to nibble on mathematics is in vain.

Feeling dizzy, Yu Hua didn't have the slightest desire to read. He touched his forehead and felt a burning sensation. The temperature felt to be around 39 degrees.

This temperature is not far from burning the brain.

"I'm not in a hurry to study for the time being today. First, cure the cold to avoid aggravating the disease. Wait for some medicine at the pharmacy, and then look for the channel to exchange French currency for the ocean." A little bit, aware of his state, he had to temporarily abandon the study plan and give priority to the treatment of the disease.
