Chapter 195 Return to the Strawberry World

Sure enough, Zhang Shuping never disappoints people when it comes to making troubles, and he announced new rules the next day.

"The next exam will be conducted in groups. Each group cannot be less than five people. The average score of each group is calculated. The five teams with the lowest average score will be eliminated."

After this rule was announced, the children present began to panic, especially those who did not do well in the last exam.

Zhang Liang took the lead in forming his own team. Except for Lu Zhihao, the other three were his followers.

Qin Hao and Pei Zhi also quickly became popular, and many children wanted to join their team.

Lin Zhaoxi stood in front of the two of them: "Sorry, we still have to discuss it."

As Lin Zhaoxi pulled Qin Hao outside, Pei Zhi quickly followed him.

When Lin Chaoxi saw Pei Zhi following him, he hesitated for a moment. Qin Hao said to Lin Chaoxi, "With Pei Zhi here, our success rate is higher."

"Okay then." Lin Zhaoxi said and waved to Pei Zhi, and the boy ran over and sat down.

"Pei Zhi, can we trust you?" Lin Chaoxi asked seriously.

Pei Zhi nodded solemnly.

Lin Zhaoxi took a deep breath: "Actually, we do not belong to this world. We traveled from a parallel world. Now we have to go back. This photo is the only clue. According to our analysis, maybe as long as we complete this With photos, you can return to your original world.”

Pei Zhi looked at the photo, but his expression didn't change at all. Lin Chaoxi asked cautiously, "You don't believe it?"

"No, I believe it. As long as you say it, I believe it." Pei Zhi said solemnly: "Don't worry, I will definitely help you return to your original world."

Qin Hao couldn't help but raise his forehead. Pei Zhi from the cheese world knew how to flirt with girls at such a young age.

"There are a total of twenty-five students including us in this photo, which means that there will be 25 students left in the end. Our current number is 45. In the end, 20 students will be eliminated. Xiang Zhangliang and his group will be There is no need for us to worry at all, what we have to do is to form three teams, then bring the ones with the worst results over here, and then help them stay." Qin Hao analyzed.

Lin Chaoxi and Pei Zhidu nodded and approved the plan.

Pei Zhi added: "It is best for us to invite one person with average performance in each group, so that one dragging three will not lower the average score too much and avoid being eliminated."

In the classroom, many children looked at Qin Hao and the other two people anxiously. In their expectation, Qin Hao, the three people who usually have the best relationship and good grades, would definitely form a team. There were only two places left in their group. , if you can join their group, you will definitely be able to advance stably.

When Qin Hao and the others returned to the classroom, several children with quite good grades expressed their desire to join their team.

Qin Hao said to the girl in front of him: "We have not formed a team. Are you sure you want to join my team? The ones I want to form are Yu Tianjiao, Yao Xiaotian, and Shao Mingchen."

The girl was stunned instantly, and the three people whose names Qin Hao read were also stunned on the spot.

Yu Tianjiao asked cautiously: "Qin Hao, did you just say you wanted to form a team with us?"

Qin Hao smiled at her: "Why, you don't want to?"

Yu Tianjiao waved her hands repeatedly: "No, how could it be? I just don't understand. It's obvious that the three of you are more likely to win first place as a team, why would you team up with us?"

Qin Hao spread his hands: "It's nothing, I just don't like this kind of rule that treats people as examination machines. If it doesn't make sense to you, then we will form a team."

The girl thought for a while and finally gritted her teeth and joined Qin Hao's team.

Zhang Liang mocked disdainfully: "Hmph, you self-righteous guy trying to go against the rules is simply stupid. Soon all three of you groups will be eliminated."

Qin Hao glanced at him: "Do you know what is the difference between geniuses and ordinary people? Geniuses will never live by the rules set by others. People like you only seek advantages and avoid disadvantages in everything, and act according to other people's rules. , You will never reach the height of genius in your lifetime.”

"You!" Zhang Liang's face turned red from the rebuke. He now felt that Qin Hao was even more annoying than Pei Zhi. This guy's mouth was too poisonous!

Soon the team formation between Pei Zhi and Lin Zhaoxi was completed, and the third team handed over the list to assistant coach Xie Ran.

After Zhang Shuping got the list, he couldn't help but feel a little annoyed. Although he was resentful about Qin Hao humiliating him in public, he had to admit that both Qin Hao and Pei Zhi were geniuses. In his opinion, geniuses should be grouped with geniuses. , so that his teaching work can be easier.

But Qin Hao and the others not only did not form a team, but each brought the students with the worst grades.

Jie Ran said with some worry: "Teacher Zhang, do we need to change our exam rules? How about we not only eliminate the last team? Qin Hao, Pei Zhi, and Lin Zhaoxi are definitely the smartest in our class." Three kids.”

Zhang Shuping shook his head with a cold face: "Smart people shouldn't use stupid methods. This is their own choice. Even if they are eliminated, they can't blame others."

After the grouping was completed, Zhang Shuping took everyone to the library: "This bookshelf is your future study scope. I have asked Assistant Professor Xie to help you make an outline. Next, you have to find out who you are from this outline. The knowledge points that need to be learned will also be the focus of our exams in the future.”

The children were all dumbfounded. In the past, they would learn whatever the teacher taught them, but now Zhang Shuping doesn't even give them books and lets them learn by themselves. This is a bit too difficult for them.

Even Zhang Liang was a little confused, but Qin Hao had already taken the lead in receiving the outline and walked into the bookshelf to start selecting books, followed closely by Pei Zhi.

After Pei Zhi distributed the books to the group members, Zhang Shuping asked: "Classmate Pei Zhi, tell me the basis for your selection of these books."

Pei Zhi was about to say it, but Qin Hao stopped him: "Since Teacher Zhang wants to test everyone's self-study ability, you shouldn't spoil it."

Zhang Shuping failed to pretend and glared at Qin Hao. Qin Hao was too lazy to pay attention to him and summoned his team members to the desk. Lin Chaoxi also took the team members to sit over. Pei Zhichong bowed slightly to Zhang Shuping and also led the team The staff moved the tables together.

"This syllabus has actually divided the scope, from counting, filling in pictures and splitting numbers in the first grade, to understanding simple sequence and natural number sequence interesting questions in the second and third grade, to finding patterns in number tables in the fourth and fifth grade. Books are all about numbers, and these are all in it.”

After saying that, Qin Hao paused and asked, "Do you know the origin of Mathematical Olympiad?"

Yu Tianjiao raised her hand and said: "I know that the Hungarian mathematics community organized a mathematics competition in 1894 to commemorate the mathematician Ertwás Roland."

Qin Hao nodded and asked, "Then do you know the biggest difference between the Mathematical Olympiad and the mathematics we usually learn?"

Everyone shook their heads in confusion.

"The Mathematical Olympiad is more difficult, while mathematics is relatively easy."

Qin Hao smiled: "You can say that. In my opinion, mathematics is like a highway, and Mathematical Olympiad is one of the highways. No matter what the maximum speed of each highway is, it will eventually converge to mathematics." On the main road."

"When we study Mathematical Olympiad, on the one hand, we need to master its knowledge points, and on the other hand, we need to learn to break out of conventional thinking in mathematics to solve problems."

"For example, a commonly used problem-solving idea in school is to set up unknowns and use one-variable or two-variable equations to solve problems. However, Olympiad math problems rarely use unknowns, but use simpler logic and mathematics to solve them. question, what we have to do now is to change our thinking, liberate our thinking, put down those equations, use Olympiad thinking to look at those problems, follow the problem-solving ideas, and find their laws."

After listening to Qin Hao's words, some children looked confused, some were thoughtful, and some suddenly realized.

Zhang Shuping walked out of the library quickly, and assistant teacher Xie Ran cast an appreciative look at Qin Hao.

Zhang Liang curled his lips disdainfully after listening: "I thought I had any great ideas, but that's all."

Hearing this, Yu Tianjiao glared at Zhang Liang: "Don't make sarcastic remarks there. You can only study well by yourself. Can you help others improve?"

"That's right, with Qin Hao and Pei Zhi here, you will never get the first place in the exam. What's there to be proud of?"

Zhang Liang was furious: "You guys!"

Qin Hao didn't have time to waste time with Zhang Liang, the middle school boy, and started talking about specific examples directly.

"For example, this question: The school bought 4 tables and 6 chairs for a total of 640 yuan. The price of 2 tables and 5 chairs is the same. What is the unit price of the table and the chair?"

"Let's put aside the equation, what should the problem-solving idea be? Based on the condition that "the price of 2 tables and 5 chairs is equal", it can be deduced that 4 tables are equivalent to the price of 10 chairs. Buying 4 tables Sharing 640 yuan with 6 chairs is equivalent to buying 16 chairs and sharing 640 yuan.”

“So, the problem-solving process should be:

Solution: 5×(4÷2)+6=16 (hands)

640÷16=40 (yuan)

40×5÷2=10O (yuan)

Answer: The unit prices of tables and chairs are 100 yuan and 40 yuan respectively. "

Qin Hao paused: "This is the problem-solving thinking of Mathematical Olympiad. Putting aside those advanced tools, it is as if the method of setting equations has not yet been born. We have to summarize the rules of this problem ourselves, and then solve the problem."

Amidst the applause, Lin Zhaoxi looked at Qin Hao talking eloquently, and suddenly felt that this guy looked like Lao Lin.

A week later, the first test after grouping was conducted. Zhang Liang's group got the first average score, while Qin Hao and Pei Zhi's group ranked third and fourth, and Lin Zhaoxi's group ranked fifth. Three more groups of members were eliminated. , that is to say, there are only 30 team members left.

Judging from the follow-up, there should be only five elimination places, but the more this happens, the more dangerous it is. Once a child is eliminated, the photo cannot be restored, and Qin Hao and Lin Zhaoxi will not be able to return to Strawberry World.

"What do you think?" Lin Chaoxi couldn't sleep at night, so she pulled Qin Hao out again to discuss countermeasures, but Pei Zhi shamelessly followed him.

Qin Hao said with relief: "Zhang Liang's team is basically stable. We don't need to worry. As for the average score of the members of the second group, it is also higher than us. What is more troublesome is the group ranked sixth this time. There are three people in this group." One is a photo member, and it would be best for us to add them to our group, but their results are not very good, and I am afraid it will lower our average score. If one of our teams is eliminated, all our efforts will be wasted."

"Then we will try to persuade them to join our group tomorrow." Lin Chaoxi said, and Pei Zhi also began to agree.

Qin Hao shook his head and said: "I think the key is not how to persuade them to join, but how to persuade the existing team members to accept them."

Lin Zhaoxi was silent. She knew that when people's own interests are involved, they often only consider themselves. This is nature.

Sure enough, when Qin Hao announced the decision the next day, most of the team members disagreed.

Lin Zhaoxi stood up at this time: "I know that doing this will take a lot of risks, but if you think about it carefully, what was the purpose of our team formation in the first place? Isn't it just to let more people stay? Now we can If there is a chance to keep three more people, why can’t we give it a try?”

The sun shone on Lin Chaoxi through the window, making her whole figure shine. Qin Hao thought, maybe this is Lin Chaoxi's unique charm.

She has never been a genius, but she is just an ordinary person. When she says such words, she is more convincing and easier to move people.

In the end, all three team members agreed to the proposal to add three more team members, and Lin Zhaoxi went to talk to these three team members. They were naturally willing to join Qin Hao's team, but they felt that doing so was like betraying their previous teammates.

In this regard, although Lin Zhaoxi also felt that it was a bit cruel, there was no better way. Adding one more member was already the limit, and the other two members did not appear in the photo. They should have been eliminated. If there was a rash change, Their fate may be that others will be eliminated.

Lin Zhaoxi couldn't take this risk. She wanted to return to the Strawberry World, where Lao Lin still needed her to take care of her.

In the end, the three of them made the decision to join Qin Hao's group. The other two people who were in the same group were accepted into the second group because their grades were not bad. Instead, the other two in the group were kicked out. .

The two people who were kicked out had no team members and could only be eliminated sadly. This also doubled the psychological pressure of the children in the training camp, fearing that they would be kicked out and could not find a team, and then be eliminated.

Lin Zhaoxi felt very guilty. If it hadn't been for her, those two team members might not have been eliminated.

Just when Lin Zhaoxi was feeling depressed, she suddenly heard Yu Tianjiao say that someone was looking for her at the public phone.

"It sounded like a man's voice."

Before he finished speaking, Lin Zhaoxi ran away and ran all the way to the public phone near the dormitory. As expected, it was Lao Lin who called.

When Lin Zhaoxi came back, he already had a smile on his face, and quietly said to Qin Hao: "Old Lin is here, and he is working as a security guard at the oasis base."

Qin Hao was not surprised either. Father and daughter were connected. Even if they had not been raised by their side since childhood, according to Lin Zhaosheng's character, it was impossible to let Lin Chaoxi stay alone outside.

After dinner in the afternoon, Lin Zhaoxi took Qin Hao and Pei Zhi to the guard room and met Lin Zhaosheng. This guy still had long hair and looked carefree.

"Master, it would be great if you could help us make up lessons, so that we don't have to worry about being eliminated." Lin Chaoxi said coquettishly while grabbing the fried peanuts in Lin Zhaosheng's lunch box.

Lin Zhaosheng rubbed her head: "Actually, you can call me like you did when we first met."

Lin Zhaoxi didn't react for a moment, and was stunned for half a minute before tentatively shouting with red eyes: "Dad."

"Oh." Lin Zhaosheng agreed simply, as if he had been waiting for this moment for a long time.

Lin Zhaoxi could no longer hold back and threw herself into Lin Zhaosheng's arms, crying loudly.

Pei Zhi looked at it confused. Isn't he a master and a disciple? Why are we father and daughter? When he saw that Qin Hao was not surprised at all, he felt more and more depressed, feeling that he had missed many secrets of Lin Zhaoxi.

After a while, Lin Zhaoxi vented her grievances these days, regained her composure, and asked curiously: "Dad, why are you willing to acknowledge me again?"

Lin Zhaosheng then told Lin Zhaoxi that he had secretly done a paternity test.

Seeing that Lin Chaoxi was about to cry again, Lin Zhaosheng quickly changed the topic: "Although I can't teach it myself, Qin Hao can help me explain it. His expressive ability is pretty good."

Qin Hao was also happy to save some energy, so Lin Zhaosheng started a small stove for the three of them that night. The next day, Qin Hao went to explain it to the members of the three teams, and the effect was quite good.

In the exam a week later, Qin Hao's team had been promoted to second place, the original second place team fell to fourth, Pei Zhi's team was third, and Lin Chaoxi's team fell to fifth.

However, this time Zhang Shuping did not eliminate any team members. It was not until the last week that he eliminated several students who had not made much progress. Lin Zhaoxi nervously took the photos and matched the names one by one.

When he found that the people who stayed were all facing each other, he jumped up excitedly and subconsciously hugged Qin Hao.

Qin Hao was stunned for a moment, and Lin Chaoxi also reacted at this time, quickly let go of Qin Hao, and took several steps back.

"Well, don't get me wrong, I'm just too excited," Lin Chaoxi explained stumblingly.

Qin Hao spread his hands indifferently: "It doesn't matter, I won't suffer anyway."

Lin Zhaoxi:

Pei Zhi couldn't help but feel sad when he saw this scene.

After announcing the elimination list, Zhang Shuping announced the final list of children representing the city in the National Mathematical Olympiad Competition.

"Pei Zhi, Qin Hao, Zhang Liang, Lin Chaoxi, Lu Zhihao."

In the end, Qin Hao and others won the gold medal in the children's category of the National Mathematical Olympiad on behalf of the city.

Lin Zhaoxi also took Lin Zhaosheng to participate in this commemorative group photo. However, to Lin Zhaoxi's disappointment, after taking several photos, nothing changed. They did not return to Strawberry World.

"Whatever tricks you are using are of no use at all." Lin Chaoxi rushed towards Qin Hao with red eyes, scratching and biting him.

Qin Hao gritted his teeth in pain: "The photo hasn't been developed yet, please let go!"

While they were talking, the two of them suddenly felt dizzy, and their consciousness woke up again, and they found that they had returned to the familiar lighthouse.

Lin Zhaoxi pointed to the only remaining formula on the wall and jumped up in surprise.

"We are back, Lao Qin, we are really back!"
