Based on the above problem-solving process, we can conclude that when the athlete spreads the parachute, the height from the ground is 99 meters, and the landing time is ...... Calculate it...... It's 8.6 seconds. Physics teacher Zheng Xicheng looked around the audience, "Raise your hand and let me see, how many people have done this question correctly?"

There was a sound of rustling in the class, and then there were many people looking around, everyone had calculated, but they still couldn't get it right, and now they all watched, who could do this problem.

Li Deli raised his hand first, and people were not surprised, Li Deli himself was the first in the class, and he would not be able to do this question to have a problem. Then raise your hand...... It's Zheng Qiuying, come on, one before the other, one or two in the class.

Zheng Qiuying also glanced at Li Deli when he raised his hand, and Li Deli replied with a smile with the corners of his mouth upturned, quite a kind of you sang and I appeared, I knew that it would be such a sympathy.

It's like a group of lions, there are male lions and lionessses in the lead, and other lions will follow, after the two raised their hands, people followed one after another to raise their hands, there were a few people in the top ten, and there were actually more than a dozen people who raised their hands, showing an expression of honor.

And Li Yachao, who ranked fourth in the class according to his admission scores, failed to do it right, Li Yachao's face was pale, and he couldn't raise his head a little when he saw Zheng Xicheng cast a reproachful look at him......

Many, many years later, when the teenagers here grow up and set foot in the social vanity fair, the threshold of happiness is getting higher and higher, from being able to have their own place in a prosperous and sharp big city, to being able to afford a transitional big house and school district house, being able to buy a luxury car to go out has more face than others, and even just hope that the family is healthy...... The definition of happiness is turned upside down, and the pressure from life is accumulating day by day, when I haven't laughed for a long time, I can't cry, and then I look back at the year, so that I can be complacent in order to do a right question, and I feel like conquering the whole world after taking a good test. Buried in the year waved goodbye, never to see each other again.

Yang Xia, who was in the front two rows, looked around the class, and finally landed on Cheng Ran.

Cheng Ran did not raise his hand.

He was just immersed in the exercises, occasionally looking up, knowing what the teacher was talking about, but he didn't seem to listen to his lecture at all.

......

At the end of the class, Yu Xiao, who was at the same table, finished writing what he was doing and handed it over, "You can help me take a look......

Cheng Ran took it, then picked up a press-core pen casually, clicked out the refill, and began to sketch on Yu Xiao's test paper, "Look...... This place should be like this...... Isn't it so that the geometry is clear at a glance?"

Since Yu Xiao understood what Cheng Ran was doing in class every day, he only had to stick out his tongue, but this kind of thing also inspired Yu Xiao's heart in disguise.

In the final analysis, the two grew up together since childhood, and they often loved to discuss some scientific issues in the past, and even at some point, Yu Xiao would have the upper hand.

But I didn't expect that just on the eve of graduating from middle school, everything I knew was turned upside down. Yu Xiao can be regarded as experiencing the feeling of the collapse of the worldview. Cheng Ran is like a dark horse that pops out of life and is unreasonable, the gap between poor students and good students like them in the past is a big gap, and the distance between him and "other people's children" is trampled on by him.

Yu Xiao occasionally had the idea that he might not be worse than him, and at this time he also began to catch up, and besides, he also didn't want to lag behind Cheng Ran much. Anyway, it is a desperate effort to do the problem and consolidate himself, maybe he will be able to break through the second pulse of Ren Du like Cheng Ran, and suddenly one day it is like being empowered by a 180-year-old old monk, reaching the level of Buddha destroying Buddha.

After finishing the physical education class, the basic activities were completed, and after running 1,500 meters for the boys, Yu Xiao was so tired that he was out of breath, but Cheng Ran, who was sitting on the flower platform, seemed to be nothing, but after running for a while, he sat next to the flower platform and quietly watched everyone run and exercise.

Yu Xiao secretly marveled at this kid's physical strength, he handed Cheng Ran a bottle of Coke, sat down next to him, the two of them snorted at the Coke, and let the coldness that had to be poured into their mouths spread to all their limbs, Yu Xiao spoke, "They don't know what you're doing, but I know...... What you actually learn every day is already very advanced, right...... Last week, it was also physical education class, I took advantage of you outside, I read the questions you put in the book, many of the questions the teacher has not taught yet, you are so advanced, is the teacher unable to keep up with your progress? Are you suddenly struck by lightning and become Superman?"

"You've just been struck by lightning...... Did your superman become after a lightning strike?" Cheng Ran glared at him.

Yu Xiao smiled.

After a while, Cheng Ran said, "Do you remember that in our unit, Uncle Liu Tian's son is now in his third year of high school, his mother is in Rongcheng, and he seems to have taken a transfer exam to Rongcheng No. 10 Middle School before, do you have any impression?"

Yu Xiao nodded, "You're talking about Liu Chengyu...... That one was always said by my dad to be the best student in our unit?"

Yu Xiao seemed to react to something, and then ...... There was an inscrutable shock on his face, "Are you ......?"

"I took a look at it, to transfer to a few good schools in Rongcheng, each school has corresponding regulations, among which the transfer exam is unavoidable, and these are all questions from their own school, and it is said that the question type is very tricky...... There is nothing to refer to for the time being, I think that Liu Chengyu has taken the exam of the tenth middle school before, it seems that he went to the second year of high school, and there will be a relevant reference range for the school's questions before the exam. I can't get these things anywhere else, and I can't go to Rongcheng to do this...... I'll go to Liu Chengyu and ask for it, how about it?"

After finishing speaking, Cheng Ran noticed that Yu Xiao was staring at him with a shocked face, and his mouth was not closed at all.

After a while, Yu Xiao said, "You know Liu Chengyu, he has always been hung in his father's mouth, although Brother Liu is older than us, it does not prevent the children in our units from being run over by him all the time......"

"But it was him, who wanted to transfer to Rongcheng No. 10 Middle School back then, but he failed in that exam...... You said that if you go to Rongcheng to enroll in Rongcheng No. 10 Middle School independently after the high school entrance examination, with your score of 706 points at that time, you may still have a little chance. The independent enrollment examination of Rongcheng No. 10 Middle School has always been called the small college entrance examination, and this year it was also on the news of Rongcheng Metropolis Daily, saying that more than 3,000 non-local students applied for the examination, and only 50 people could be admitted...... There are more than 3,000 of them, all of whom are qualified students in the province!"

"I don't say anything, you must know that high school has already started, and the next transfer exam will end in the first year of high school, and the progress of those top high schools in Rongcheng is incomparable to our first high school...... Moreover, the top high schools in Chengdu generally do not accept transfer students, and the transfer exam is to respond to the national policy and not block the road, but you must know that the transfer exam is a roadblock, and it is to make it difficult for students outside to retreat......"

"Are you going to ...... Hell difficulty!"

"Ah, I made a promise to give it a try. ”
