This is a step-by-step process, and this is the core reason why the question sea tactic can quickly improve your performance in a short period of time.
A large number of math problems of the same type are given, and the difficulty is gradually increased to enable problem solvers to master relevant knowledge points and improve the speed of problem solving.
Of course, the advantages and disadvantages of the question-sea tactic are very obvious. The advantage is that it improves performance, but the disadvantage is that it consumes a lot of valuable time.
However, can the time of a poor student be called valuable?
Yu Hua believed that the most important thing Tan Qing lacked was time. There were still a few months left, and the tactic of using question waves was more useful than any learning strategy.
Today is the weekend, it is noon, and it is the school holiday. Some students leave school and go home to visit relatives, while the remaining students either stay in the dormitory to rest or go to the library to study.
Tan Qing carefully studied the problem-solving ideas given by Yu Hua, and gradually understood the essence of the wrong question on the draft paper like a cocoon. Fifty minutes later, at one o'clock in the afternoon, today's third class was completed.
Yu Hua put down his pen and placed the draft book with more than 20 pages of math problems in front of Tan Qing. His words were serious: "Hanzhi, your task today is to finish these problems. You are not allowed to sleep until you finish."
Yu Hua spent fifty minutes and wrote about forty questions of basic elementary function types. Some of these questions were compiled by Yu Hua at random, and some were function questions in his memory, from later generations of Jiangxi Volume, Jiangsu Volume, and Sichuan Province.
There is a correlation between the questions and the questions, and the difficulty increases slowly.
As long as you finish these forty questions, you can basically master the comprehensive knowledge points about basic elementary functions, thereby improving Tan Qing's arithmetic foundation.
"Okay, I will definitely finish it." Tan Qing looked at the brand new draft book on the table, swallowed his throat involuntarily, took a deep breath, his eyes were firm and serious.
"That's good, let's do it first. Today's homework tutoring will be here for the time being. I'll leave first." Seeing this, Yu Hua smiled slightly and after giving instructions, he took out the schoolbag containing various items from the drawer and said goodbye to Tan Qing.
Get up and leave.
According to the original plan, today he was going to find a bookstore or printing house to print a collection of wrong math problems.
After three days of preparation, Yu Hua, who is extremely efficient, took advantage of his spare time to sort out various types of mathematical problems, from the first draft to the official version.
Today is the day when Yu Hua’s collection of wrong math questions was born.
Yu Hua left, carrying his schoolbag with expectation and longing in his heart. He was about to leave his first belongings in this era and take the first step towards the future.
The collection of wrong math questions is very small, but the life of the Republic of China is very large.
After leaving the classroom, Yu Hua went straight to the gate of No. 4 Middle School.
…
The classroom was quiet and cold, with only Tan Qing left.
"You are not allowed to sleep until you finish..." The footsteps in the corridor outside disappeared. Tan Qing looked at the table, looking at the brand new draft book full of math problems. He felt a little numb in his scalp, thinking about Yu Hua's story in his mind.
Instructions, take a deep breath.
Tan Qing was very aware of the amount of questions that Yu Hua assigned. Although he thought the number was small, he never thought that he would watch Yu Hua use half of a brand new draft book.
God, that's half of it!
Who knows how Yu Hua did it.
The mood was quite heavy. After a few seconds, Yu Hua's firm and confident eyes appeared in Tan Qing's mind. He gritted his teeth, adjusted his attitude, collected his emotions, picked up the pencil in his right hand, and looked down at the draft book.
There is no point in complaining and there is no point in being sad.
Since it is the path you have chosen, then go on unswervingly without any regrets.
Tan Qing turned his attention to the first math question in the draft book. He thought it was very difficult. After taking a look at it, Tan Qing's eyes suddenly brightened.
Simple.
Three times, five times and two times, five times and two times, he wrote down the answer, and the first simplest basic elementary function question was solved. After finishing it, Tan Qing was very sure that he got the answer right, and he couldn't help but build up a little confidence in his heart.
Moving his eyes downward, Tan Qing glanced at the second question and felt that the question was a bit familiar. He frowned slightly and suddenly remembered the knowledge points that Yu Hua explained on the first day, and suddenly realized it in his mind.
I see.
Once you have the ideas for solving the problem, you can apply the formulas and write with ease.
It was fluent and easy, and the second question was finished in less than two minutes.
"Classmate Yu Hua, you have really worked hard and I will never forget your feelings."
After solving the second question, which was slightly more difficult, Tan Qing looked at the question on the draft paper. He still didn't understand Yu Hua's intention in setting the question like this. He was moved in his heart and silently remembered it.
Yu Hua specially took care of his mathematical level, from simple to easy, and the difficulty gradually increased, but it would not exceed his current level.
As long as you pay attention, you can definitely figure it out.
It took a lot of effort to come up with this question.
He felt that the lecturer from the private Nankai University that his family hired during the winter vacation was not as effective as his classmate Yu Hua in providing academic tutoring.
After successively conquering two mathematical problems that were like an enemy city, Tan Qing had already established preliminary confidence in his heart, his eyes were clear and translucent, and his heart was filled with a steady stream of fighting spirit.
In this case, we must not let down classmate Yu Hua.
Refresh the questions!
Study questions to improve your grades!
"70 points, 70 points, Tan Qing, you can definitely do it."
…
In the afternoon, the sky was clear.
A warm sun hangs in the sky, releasing a steady stream of warmth.
Five districts in the north of the city, Beibing Hutong, Huangchenggen Bookstore.
Yu Hua stood in front of the Royal City Gen Bookstore, looking at the building in front of him, which was not as big as Chongwen House. As soon as he entered the courtyard, the mottled and almost rotten wooden door, the shapeless threshold, and the right side of the door stood a block full of vicissitudes and traces of time.
The house number——Beiping Huangchenggen Bookstore.
Through the open door, some workers and foremen in gray robes were busy inside. In the middle of the yard stood a middle-aged man in a robe and mandarin jacket, as if he was in charge.
"It meets my needs." Yu Hua looked at the Huangchenggen Bookstore in front of him, the corners of his mouth twitched slightly, and he couldn't help but hold his forehead. He felt helpless, thought about it, sighed, and left without turning around.
I've already come here, and I'm too lazy to look for another home.
To be honest, if it hadn't been for the reassurance of the guide just now, Yu Hua would not have believed that this was the famous pirate dealer in front of Peking No. 4 Lieutenant Colonel, Huangcheng Gen Bookstore.
Is this called a bookstore?
It is clearly a printing workshop.
It's still small and can't be any smaller.
Well, no matter what, as long as I can print a collection of wrong math questions, Yu Hua doesn't ask for much.
Huangchenggen Bookstore is well-known in the piracy market of major universities in Peiping and is a backbone in the field of piracy. Books adapted from world famous classics such as the Cathedral of Saint-Dère in Paris and How Steel is Tempered, which were once famous in Peiping, are from the Huangchenggen Bookstore.
In the hands of the bookstore, while other pirates were still playing the game of splitting a classic into five copies and printing it, Huangchenggen Bookstore was directly adapting the classic.
The famous story that originally praised the kindness, friendship, and self-sacrifice of the lower class people has turned into a story about a feudal businessman who traveled to Paris in the 15th century and finally established the Saint-Father Church in Paris. Regardless of the meaning of the existence of this feudal businessman, just rely on others
The courage to change a famous work is enough to be praised.
Yu Hua glanced at this book and never read it. As for the book "How Steel Was Tempered", which became "How Steel Was Tempered", Yu Hua also didn't read it.
Well, I don't have the courage.
However, Yu Hua really didn't expect that the famous Huangchenggen Bookstore was just such a small printing workshop.
