Luo Fei didn't expect that the first new friend he gained after his rebirth was actually a science bully from Lucheng Middle School.

In the previous life, two people who basically had no intersection, because of a bullying, a help, and a visit, thus sparking a spark of friendship.

Although the time of acquaintance is relatively short, in Luo Fei's eyes, Zeng Bo, a thin boy who looks like a nerd, has a vision and level of understanding far beyond the content of textbooks, and also exceeds the average level of children in this small eastern county.

For Luo Fei, a reincarnated middle-aged uncle, his experience and insight are too much beyond his peers, including Kevin, the thinking level of boys of the same age in Lucheng Middle School stays on studying, taking exams, having fun, and chasing girls, and he doesn't have too much understanding of the world and the future.

Although Luo Fei didn't mind enjoying this kind of young man's world, he did sometimes feel a sense of loneliness, and this loneliness of lack of reciprocal communication was alleviated after meeting Zeng Bo.

Whether it is because of his family background or because of various factors in the process of growing up, Zeng Bo has a rationality beyond his peers; similarly, Luo Fei's wisdom and foresight as a reborn person also made Zeng Bo, who has a high self-esteem since he was a child, secretly admire; it is natural that the two have become good friends who have nothing to say.

Of course, it was not only Luo Fei and Zeng Bo who became friends, Kevin naturally joined this circle.

After all, Zeng Bo's house is big and comfortable, Zeng Bo's mother is beautiful and very enthusiastic about people, and Zeng Bo's games are too many and fun......

As a result, they have become a new landscape of Lucheng Middle School.

Except for being in their respective classes during class, these three people are simply inseparable in their spare time.

Originally, there was only a duo of Luo Fei and Kevin, but now there is another Zeng Bo.

Zeng Bo's home is not far from Dongcheng, but the three of them all walk together after school, and the two of them send Zeng Bo home before driving to Xicheng, where they live.

Although Zeng Bo will not participate in the "big military parade" that Luo Fei and others are used to, since he has these two tall and big friends around him, the little overlord who has nothing to trouble him has died down, and his living environment in school has also improved a lot, and he has become cheerful.

At the beginning, seeing the top student in the whole school, the future champion of science, Zeng Bo, and the poor student in the slow liberal arts class mixed together, the head teacher of the second (3rd) class of high school was unhappy, he was afraid that the treasure jade in his hand would be damaged by Luo Fei and Kevin.

Because Zeng Bo is the biggest trump card in the hands of the class teacher of the second (3) class of high school, if he does not perform well in the future because of his bad students, then the performance and promotion of the class teacher will be affected.

However, after a period of time, the head teacher found that Zeng Bo's grades did not fluctuate, although he spent less time on studying in his spare time, his academic performance was one step further, which made the big stone in the head teacher's heart finally fall.

Since Luo Fei and Kevin often go to Zeng Bo's house for parties, Zeng Bo's big house has also become lively, full of boys' laughter and full of vitality.

It's just that Zeng Bo's mother is still often away from home, and she has to work until late every day before coming back.

Zeng Bo has long been accustomed to this, because he already has two more friends in his life.

People who have friends are not lonely.

......

However, life is not all smooth sailing.

In an exam that just ended, Kevin once again scored an average score lower than the average of the slow class, and in the face of the test papers full of red crosses everywhere, Kevin looked at it with a sad face for a long time, and said bitterly:

"If I fail the exam a few more times, I guess my dad is going to be in a hurry, and the last time he came back, he told me that he wanted to take me to the north to study, I didn't want to go to the north, it was too boring. “

"If you're worried about your grades, take your studies seriously, and you'll always get something. “

Zeng Bo said lightly while reviewing the physics exercises.

Although he is only a sophomore in high school, Zeng Bo has already begun to prepare for university courses, and these knowledge in high school are no longer enough for him.

"You said it easily, it's not that I haven't taken it seriously, but what the teacher said in class, when I get home, I can't remember it after a few days, and I don't have your Xueba's brain, it's difficult. “

Kevin sighed.

"Learning requires methods, and once you master the methods, it will not be difficult to learn. “

Zeng Bo understated.

His grades have always been very good, and this time he is still the first in the school, so he has the confidence to say so.

"What way, you can pass on the scriptures to us. “

Luo Fei wasted no time in proposing.

He did well in this exam, but the two major weaknesses of English and mathematics still dragged him back.

Although Zeng Bo has become a rare friend in high school, Luo Fei has not forgotten his original intention.

To get his learning method from Xueba's mouth, in addition to buying it with money, the best way is to make him willing to share.

Now that they are good friends, it makes sense to ask good friends to help.

Therefore, Zeng Bo, who has always been calm and rational, did not think much about Luo Fei's request, and he quickly replied:

"Do you know the 'Ebbinghaus Forgetting Curve'?"

Luo Fei frowned, searched in the memory bank, and said slowly:

"It's like saying that when information is fed into the brain, forgetting begins. The rate of forgetting is fast and then slow over time, especially in the short period of time that has just been recognized, and forgetting is the fastest. “

Zeng Bo nodded approvingly and added:

"The forgetting curve was discovered by the German psychologist H. Ebbinghaus, which describes the gradual and intuitive description of the human brain's forgetting of new things, and people can grasp the forgetting law from the forgetting curve and use it, so as to improve their self-memory ability. “

Although Luo Fei had heard of this research result in his previous life, he didn't really have an in-depth understanding, so he could only nod slightly when he listened to Zeng Bo's description at this time.

Zeng Bo saw the confusion in Luo Fei's eyes, he found a piece of white paper, drew the X axis and the Y axis with a pen, and then drew a long curve from the highest point of the X axis downward, this curve descended in a steep slope, and after approaching the Y axis, it tended to be straight infinitely.

"This is the law of forgetting in people's learning, the process of forgetting is very fast, and it is fast and then slow. If you look at this line, you will find that after a day, if you don't review it quickly, you will only be left with 25% of the original knowledge. Over time, the rate of forgetting slows down, and so does the amount of forgetting. “

"Ebbinghaus did an experiment in which two groups of students studied a text, and group A did not review it after studying, and the memory rate was 36% after one day, and only 13% after a week. Group B reviewed according to the Ebbinghaus memory rule, and the memory rate was 98% after one day and 86% after one week, and the memory rate of group B was significantly higher than that of group A. “

Zeng Bo was gesturing and talking eloquently, and Luo Fei nodded again and again.

"My learning method is based on the theory of this 'Ebbinghaus forgetting curve', as long as you master my method and stick to it, it is very easy to get good grades. “

Zeng Bo said this, with a rare look of pride on his face, a kind of pride exclusive to scholars.

Luo Fei couldn't help but smile, he finally waited for this moment.

Kevin leaned over with a confused expression, as if he was afraid that he would be pulled down, scratched his head and said:

"What are you talking about, what curves, what forgetting, you can't understand anything, can you speak human words?"

Zeng Bo shrugged his shoulders and made a helpless expression.

Luo Fei was in a good mood at this time, he patted Kevin's shoulder and said with a smile:

"Next, we're going to get serious into learning. “

Kevin looked at Zeng Bo's expression, and then looked at Luo Fei's demeanor, knowing that the two were not joking.

His face fell again, his body leaned back, and he exclaimed:

"Don't!"
