"What is an assembly line?" Curious babies ask.

"It's five people doing the test paper at the same time, skipping the questions you can't do, and passing your test paper to the next one after you finish the test paper, so that he can see if he can do the questions you don't know. The next person takes it, and let's see if you will have the empty questions. Yes, you just do it. No, then keep going. If it doesn't work until the end, then show me. ”

"Good!"

"It sounds so powerful, it's worthy of nothing."

"Who's going to be with me?"

"Let's do it together."

"There are two people left, who else?"

……

Song Cheng had already stood beside Jian Bai in an orderly manner, for fear that others would not know that he and Jian Bai were in a group. Wang Qiao pulled Gong Xiaoyu over as well, "Baibai, let's go together." ”

"Okay, I'm doing my homework faster, so we can have one less person in our group." Jian Bai also naturally classified Song Cheng as his own.

However, Lan Xin, who watched the whole process, pulled her simple white hair quite angrily, "Lord Bai, why are you using your mind and eyes on how to be lazy, and you are also encouraging children to copy homework, what a bad guy...... Yes! ”

"In vain, why are you slapping yourself on the head?" Gong Xiaoyu glared at Jian Bai curiously.

Jian Bai smiled evilly, "I suddenly felt a little headache just now, but now it's okay." ”

With a bit of the nature of the group stage, everyone suddenly put away their laziness. After the homework was turned over, he didn't make any more noise, so he sat down obediently on the ground and began to do the test papers. After a while, only the sound of paper pulling and writing was left in the whole long pavilion, and if it weren't for the wrong place, it would really have a bit of an exam.

Listening to the sobbing mixed with angry scolding from the top of Lan Xin's head, Jian Bai was also in a good mood and began to work on the question after cross-legging.

With a cool and majestic wind, he rolled up the green vine slightly, shaking off the figure sitting in the long pavilion. Every child has a serious and unyielding spirit on their faces, and no one wants to drag everyone back and let the group be the last to finish.

The environment has a great impact on people, and some of these children usually can't sit still after less than an hour of homework. But now it's different, the friends around them are seriously completing their own test papers, and even if they can't bear it, when they see this situation, they will grit their teeth and continue to persevere.

Because there is a row of plane trees on the left side of the pavilion, it is impossible to cross the road. Therefore, very few people pass through the pavilion, and most of them only walk through the path on the right side of the pavilion.

So when those who went out to buy vegetables and came back, when they passed by, they found a bunch of radish heads obediently sitting in a row in the long pavilion to do their homework.

"Is this an outing organized by the teacher to do homework?"

"These kids are so well-behaved, they know how to do their homework on the first day of vacation."

"I don't even want to talk about that in our family. Every time it was time for school to start, and when I was dying, I started doing my homework in a panic. ”

"Wait a minute, I'll see if they're still here, aren't they? When the time comes, I'll ask my children to come too. ”

"Okay, let my son come too. When the time comes, they will be together. ”

Some parents with children will reprimand when they see this scene, "Look at how serious other children are, they are all doing their homework." You see that you know how to play all day long, how can you be embarrassed? ”

And those old ladies who came back from morning exercise also smiled kindly when they saw this scene, "Ouch, these good boys are so serious." ”

The children are not distracted, and they can hear the words of passers-by clearly. This is just the act of getting together to do homework and copying homework, and inadvertently made them suddenly become other people's children.

This made them a little fluttery, originally they felt that they had been doing the test papers for a long time, and they were quite tired and wanted to rest. But the constant praise of passers-by made them embarrassed to give up halfway. Although their attention was diverted a little, they were like chicken blood, and they did it more seriously, and their backs were straight.

As time went by, I didn't expect that there were children who brought their own cardboard and homework. There were benches on the left and right sides of the pavilion, and they sat on the left side against the tree, and the children who were brought by the parents did not disturb them, but sat down on the bench on the right.

"Son, you are doing a good job here today. Later, my mother will bring your favorite toffee and come to see you. I don't know if it's because the current folk customs are really simple, or if she thinks it's safer for a bunch of children to be together. Anyway, in the end, these parents who brought their children here were very relieved to leave their children here, and they went straight home.

The appearance of this scene was also something Jian Bai did not expect. She turned her head and saw that there were six or seven more children, all of varying ages. The bigger one might be about the same size as theirs, and the smaller one was estimated to reach her waist. Two of the children sat on the floor for unknown reasons and without putting cardboard.

Jian Bai was a little unbearable, and handed over the extra cardboard in the plastic bag, "You can sit here." ”

The two children looked a little scared, and timidly took the cardboard and said, "Thank you, brother." ”

Hearing this, the companions suddenly burst into laughter, and pounded the test paper vigorously, "Jian Bai, they call you brother." ”

"Brother...... Hahahaha...... Brother ......"

Jane's white face turned blue, although she was a little stronger and a little darker, but she couldn't be a brother. People who know her well also know what she looks like when she has long hair, and no one will misunderstand.

But these children are different, they only see this black and strong big child with short hair, isn't this my brother, why are you laughing?

Seeing that the child was a little confused and anxious to laugh, Jian Bai relented first, "It's nothing, brother is brother." My name is Jian Bai, what are your names? ”

"My name is Wang Dabao, and this is my brother's name is Wang Xiaobao. Our family is on the fourth floor of this building, and I am now in the sixth grade at Guangming Elementary School. My mother's name is Liu ......, "I feel that this child named Wang Dabao is also true and sincere, so I asked him for his name, and he told him about the situation at home."

"Okay, I see." Jian Bai had to interrupt, for fear that this child named Wang Dabao would not have a door in his mouth, and everything at home would be shaken out at that time, which would be fun.

"You guys go ahead with your homework, and we'll play together when we're done."

Hearing that they were playing together, the two children suddenly smiled and came to their senses, and the unhappiness of being forced to do their homework before was thrown away, "Thank you, Brother Bai." ”

Jian Bai was powerless to argue, but just waved his hand to signal them to continue.

When she sat down, what she saw was Wang Qiao's red face with a suffocated smile. However, the evil-eyed Jian Bai not only didn't say that they could laugh if they wanted to, but on the contrary, he gave them a look and asked them to hold back their laughter.

In this state, even boring homework becomes interesting. After the volume was made, the assembly line project began. The long pavilion is also lively, everyone asks this formula one by one, asks the example questions, and complains from time to time that the test paper is so perverted or something.

Everyone is also trying to do a good job in the questions at hand, and strive to make the next problem less to get in hand, so that their group can complete a little higher. On the contrary, the last one was a lot easier, because he couldn't do the questions he couldn't do before, and he couldn't do anything about it. simply sorted it out, and gave it all to Jian Bai.

Jian Bai's group, with the blessing of her and Song Cheng, has already been completed. However, in order not to discourage the enthusiasm of others, she handed the test paper to Wang Qiao and Gong Xiaoyu again, and asked them to see what they didn't understand.

Then he took out the "Fundamentals of Advanced Mathematics" that Jian Yu put in the room and handed it to Song Cheng, "Look at it, can you understand?" ”

Jian Bai just tentatively handed Song Cheng a book of knowledge that he had never been exposed to, wanting to observe how strong his learning ability was. Higher math thinking is broader, more divergent and freer, but this is for people who have a certain knowledge base. If you don't pave the way for high school mathematics, then self-learning high math is undoubtedly a fantasy.

Song Cheng took the book, first flipped through it roughly, and was instantly attracted by the content inside. He turned to the chapters on spatial analytic geometry and vector algebra, and so far they have only been exposed to the knowledge of two-dimensional planes. He has his own vague conceptual understanding of three-dimensional space, but it is not as clear and to the point as it is written in this book.

He is also very unfamiliar with many proper nouns in it, but looking at the concepts of these nouns, he seems to know something vaguely. Like the concept of a vector, it is a quantity that has both magnitude and direction. There are also linear operations, decomposition formulas, modulus length coordinate expressions, etc., which extend from it, and many novel conceptual expressions, which make him eager to dive into it and slowly study it thoroughly.

"I... Can I borrow this book and read it slowly? Song Chengliang's sparkling eyes were filled with urgency and longing.

Jian Bai got goosebumps when he saw it, and he agreed without thinking about it, "You can take it and see it." ”

But as soon as she said that, she reacted. Oh my God, this is her brother's smuggling, if she gets caught...... But seeing Song Cheng's look of joy that she was about to take off because she borrowed the book, she couldn't say anything. Forget it, her brother's side will come to cover the water and earth.

The other two groups also handed her the test papers one after another, because Song Cheng had now plunged into the book, and he couldn't let him help, so the speed of the process of filling in the process naturally slowed down.

She took the test paper and was about to start working on it, but she felt that the corridor was quiet for a while. Jian Bai looked up with some confusion, but saw that her friends were all blinking and looking at her, and the meaning was self-evident.

Jian Bai laughed and waved his big hand, "Let's play, I'll call you later." ”

Oh~ The children who got the reply all stood up and ran out of the long pavilion with a puff of smoke. They actually held back all morning, and finally liberated.

Seeing that they could go out to play after handing in their homework, the children in the neighborhood couldn't sit still and began to learn from each other. Wang Dabao nodded, and first tentatively handed the homework in his hand to Jian Bai, "Brother Bai, we are also done, can we go play?" ”

Jian Bai couldn't laugh or cry, "You go." ”

Dabao, who received an affirmative answer, couldn't maintain his chubby face anymore, and beckoned to his little friend, "Xiaobao, come and hand in your homework, and we can only play after handing it in." ”

Jian Bai, who wanted to explain, was tightly blocked by this sentence, and the children in the neighborhood cheered and handed over their homework to Jian Bai, and then ran out with most of them.

Jian Bai's attention to safety has not yet exited, and the person has already run away.

What to do, so grumpy......

Now the two of them were in the pavilion, and after seeing that the thin Song Cheng was still in place and looking at the book intently, Jian Bai interrupted him unceremoniously, dragged his hand and rushed out, "Let's go, let's play." ”

Jian Bai had a lot of strength, and Song Cheng couldn't catch it off guard, so he was taken away in a strange posture, and he even grabbed a pen in his other hand. But he didn't have the slightest dissatisfaction, and even quietly put some force on his leg, just so that Jian Bai could hold his hand.

"Boys, I'm coming." Seeing children playing eagles and chickens in the small square of the park, Jane decided to save them from this boring game.

So for the rest of the time, there were constant rumors in the park, mixed with laughter and laughter of "carrot squatting", "pink radish squatting", and "wrong and wrong".

The sound spread far and wide, and even those who heard the children's crisp laughter couldn't stop laughing......
