Reborn Tech Scholar

Chapter 18 Back to School
January 1, evening, sunset

Qin Yuanqing stood at the school gate and looked at the red banner at the school gate. The banner was celebrating his CMO championship gold medal. Even though more than half a month had passed, the red banner had not been taken down.

This time, I took a direct flight from Beijing to Ludao Airport. After getting off the plane at Ludao Airport, Qin Yuanqing did not choose to go back to No. [-] Middle School in the county, because it was already the New Year's Day holiday.

So Qin Yuanqing went directly from Ludao to go home by boat.

Enjoying this rare New Year's Day holiday at home, my parents were very happy to know that he won the CMO gold medal, and then told Qin Yuanqing that reporters had been coming to interview them during this time, and the town leaders came to offer condolences, including a bonus of [-] yuan. .

With this 10 bonus, plus the 15 yuan Qin Yuanqing remitted to his father before, there will be [-] yuan, and the family's finances will be a lot easier.

Dad said that he wanted to build an extra floor to avoid the summer heat.Qin Yuanqing was originally engaged in engineering design. Although it is not a house construction design, many things are similar.

The old house has been built for more than ten years. The concept of rural architecture in the 90s was relatively backward. The foundation only used a stone as a ring beam, and then the walls were built directly, without columns.The old house is next to the road. The foundation has sunk for more than ten years, resulting in uneven settlement. Cracks have appeared in the walls. It can also be seen that the floor will leak in rainy days.

Therefore, the old house cannot continue to be built, otherwise it will become a dangerous house, and the money spent will be wasted.

In the original trajectory, whether to build another layer on the basis of the old house or rebuild it, Qin Yuanqing chose to rebuild after considering it all.

At this time, labor costs and material costs are relatively cheap, and a three-story rough house can be built at around 20 yuan. If we wait until 2015, the prices of cement, steel bars, and sand have all increased, and labor costs have also increased. The same building The area and the same style cost 38.

After persuading his parents, Qin Yuanqing went to the Internet cafe, downloaded the cad, and redesigned the house he originally designed based on his memory. However, he also learned a lesson. The single width of the stairs was kept to 1.5m, which is not suitable for too narrow stairs in the countryside. The 1.25m width of the original design is obviously narrow, and he was also complained a lot by his father.

The master bedroom has also been optimized, the bathroom has become smaller, and it is also divided into dry and wet areas, leaving room for cabinets, and the overall layout is much more reasonable than before.

Then I found a master Tushui in my father, Qin Yuanqing explained it carefully, including architecture, structure, water supply and drainage, electrical and so on, and Qin Yuanqing left with confidence.

This time, when he returned to school, Qin Yuanqing received a grander welcome than last time. The principal specially held a celebration party on the playground. Qin Yuanqing didn't speak last time, but this time he couldn't run away. Qin Yuanqing chose '90 not to break down. Generation' as a speech.

"Students and teachers, I was born in the 90s. Most of the classmates present here are born in the 90s and 90s. In society, there is a synonym for the 'Beat Generation'!"

"Beat generation, such a big hat, buckled on us, we can't breathe..."

"In fact, we are by no means of the 'beat generation', we belong to the generation of individuality, and the era belonging to our post-90s is beckoning to us. History will eventually prove that our Chinese generation is stronger than the previous generation, and the blue is better than the blue. !"

"Some people may be angry, we don't respect our elders, we are arrogant and arrogant! But what I want to say is that the revolutionary predecessors went one after another to establish a new China. They did not just provide a complete and peaceful country for future generations, they did not I just hope that my children and grandchildren will get better and better!"

"A generation is stronger than a generation, and the youth is better than the blue! This is our greatest tribute to the revolutionary ancestors!"

. . . . . .

At the end of Qin Yuanqing's speech, there was thunderous applause, and every classmate felt very excited, almost felt that Qin Yuanqing had spoken for them.

After the celebration, after a brief speech by a senior county official, on behalf of the county government, he rewarded Qin Yuanqing with 20 yuan, and encouraged Qin Yuanqing to make persistent efforts to take the Huaxia Olympic Team to IMO and win glory for the country!
Qin Yuanqing and senior county officials took a group photo with a sign representing 20 yuan!
Qin Yuanqing did not expect that the county would reward him with 20 yuan for winning the CMO championship. This is a big deal.

However, Qin Yuanqing soon discovered that, not only that, the Provincial Department of Education, the Provincial Mathematical Society, and the Municipal Education Bureau then rewarded him with a total bonus of 50 yuan.

This is Huaxia, as long as the reading results are good enough, there is nothing to worry about.Even Qin Yuanqing still remembers that there was a college entrance examination professional who took the college entrance examination every year and was admitted to Shuimu University and Yanda University.

Qin Yuanqing didn't transfer the money to his father, so much money is not safe, it is more appropriate for him to handle it in person.

Anyway, there are only 10 days left until the final exam, and I will go back when the final exam is over.

Qin Yuanqing accepted several interviews, mainly from counties, cities, and provinces. As for the interviews with national-level media, they were already conducted at the closing ceremony of the CMO.

Qin Yuanqing quickly reintegrated into the environment at school. He read books every day, gave lectures to his classmates, and talked and laughed with them. As for love letters, he received a bunch of them every day. Pretty girl classmates.

It's just that the so-called good-looking skins are the same, and the interesting soul is one in ten thousand!

Qin Yuanqing didn't plan to fall in love in high school either. When he went home after the final exam, he had to rush to the capital for the second training camp. He didn't want to fall in love, and he didn't have time to fall in love!
Therefore, the goddess has dreams, and King Xiang has no intentions!
All of a sudden, I don't know how many girls are crying in bed, and how many male students are outraged by this!

On this day, during the evening self-study, Qin Yuanqing wrote the topic on the blackboard:
"Classmates, I will share a question with you next!" Qin Yuanqing said to the classmates, "Now give everyone 20 minutes to do this question!"

This question written by Qin Yuanqing on the blackboard, (1) is the type of matrix and transformation, the linear transformation corresponding to the known matrix turns point A (x, y) into point A' (13, 5), try to find M The inverse matrix of , and the coordinates of point A. (2) is the coordinate system and parametric equation. Given the known straight line l and circle C, try to determine the number of their common points. (3) is an inequality, solve the inequality |2x-1|<|X|+1.

Qin Yuanqing looked at the classmates who were working hard on the questions, and his face was full of trouble. This was the last question for next year's college entrance examination when he was doing the question, so it was used as a benefit and as today's case question.As long as the students are attentive, they will get the 14 points in the college entrance examination next year.Yes, although it is a three-question question, you only need to choose 2 questions to answer.

Now everyone has completed the entire high school textbook knowledge, and the matrix has been learned.Qin Yuanqing still remembered that many students did not know this question and could not get points.

For example, in this (1) question, we must first find M through the matrix, and then find the value of M'.In order to obtain the final value by listing a new formula. (2) The question is to convert the equation of the circle to find the coordinates of the center of the circle and the radius. (3) The question is decomposed into different situations. One is x<0. After transforming the original equation, x>0 is obtained, and the result is that x does not exist.In the second case, when 0≤x≤1/2, the range value of x is obtained after the original equation is converted.The third case is x≥1/2, the range value is obtained, and then the three cases are combined to finally determine the solution set of the original inequality.

This question is not difficult, but if it is placed at the end of the real college entrance examination question, because everyone was so nervous about the question before, when it comes to this question, there will be a lot of knowledge points forgotten or there is not enough time, and it is easy to be tragic.

Qin Yuanqing only got half of the score for this question at the beginning.

Sure enough, the students who have not gone through several rounds of review have not yet reached the peak of their combat effectiveness. There are only two people in the class who have written the complete calculation process and answers, and most of them have not even completed the first question.

Qin Yuanqing asked Lin Yuling to come up to solve the problem, and then he explained one by one next to him, and wrote down the knowledge points in the book on the blackboard.

He didn't know how many classmates would remember this question, but the opportunity had been given, and if he didn't seize it, he couldn't blame others.

During this period of time, Qin Yuanqing took the real questions or test sites for next year's college entrance examination that he remembered, and modified them a little as case questions.

If he had a good foundation, he could even be admitted to Shuimu University or Yanda University if he was not careful.

"Very good, Lin Yuling's solution is very complete. This question basically covers the knowledge points of mathematics electives. I hope everyone can use this question as a case question to consolidate the knowledge points of the elective." Qin Yuanqing said.

He found that sometimes the environment is really important. Although he didn't take the monthly test last time, his grades in the monthly test have been greatly improved. Lin Yuling ranked 38th in the grade, and three other students entered the top [-]. Compared with Much progress has been made before.

In this final exam, there may be even greater results.At least Qin Yuanqing is sure to win the first place in the age, and the average score of the class will also be pulled up for him.

In 2009, on January 1, the sun was shining and the temperature was about 14 degrees.

The entire Gimpo No. [-] Middle School entered the final exam session. Senior [-] and [-] were separated from each other. There were only half of each class left for senior [-] students, each with a desk, and the rest were arranged in the multimedia hall and other spare classrooms.

Midterm and final exams are the most important exams in schools. Teachers have tried every means to prevent students from cheating.

It's just that for some smart classmates, no matter how well prepared you are, that's one foot high and one zhang high, and it doesn't matter to him.

And most of the students are well-behaved and honest, even if two people are at the same table, they don't dare to take a peek.
