"Stop laughing, let's get to the point." Fu Feng picked up a pen on the table, and turned the answer in his hand over, using it as scratch paper to write and draw.

Nineteen Nian was still giggling, not like he was studying.

She said to him, "That's not my pen, it's in my bag." By the way, I also brought scratch paper. ”

Because of her voice, Fufeng had to suspend the lecture.

At this moment, he really wants to say something, can you listen to me well?

Nineteen Nian unzipped the schoolbag placed on the bench next to him, took out the pencil case and a brand new practice notebook.

She opened her pencil case and took two pens of different colors, the black one for him and the blue one for her.

"No, you can keep talking." Nineteen Nian put the exercise book next to him.

Fufeng closed the cap, put the previous pen on the table, picked up the pen she had handed her, and opened the exercise book, folded it, and pressed it against the test paper.

"Look at the fifth question, I don't know if you really can't do this question or if you accidentally did it wrong, or you should do it again." Fufeng was about to hand her the early manuscript.

"Don't do it, you can explain it directly." She wouldn't do it anyway. Nineteen Nian thinks so.

"The position of the corresponding point of the rational numbers a,b on the number line is shown in the figure, then?" Fufeng suddenly paused after reading the question, and he asked, "I want to know why you chose C, this question is either A plus B is greater than 0, or A minus B is less than 0, how did you choose C, A minus B is equal to 0?" ”

Nineteen Nian bit her lip, and she suddenly remembered the scene when she was doing the question, which she seemed to have been blinded casually.

"This question...... I'm blinded. She smiled awkwardly.

Fufeng looked at her with disdain, "To borrow a phrase from our math teacher, this question, I won't be blinded with my eyes closed." ”

"Then don't look at the question, try it with your eyes closed!" Nineteen Nian raised his lips proudly, "Maybe you're not as good as me!" I guess you can write the answer to the question. ”

His face was as black as carbon again, and he waved his hand and said disdainfully, "Okay! If you can't refute it, it won't be a refutation. ”

He opened the cap of his pen and drew a number line on the papyrus, but since there was no ruler, the number line was not straight at all.

"You should know the number line." Fufeng turned his head and asked her, "If you don't know, you can open the book to the section of the number line." ”

Nineteen Nian propped his head, looked at the unpunctuated straight line he drew on the scratch paper, and said in a daze, "Our junior high school math teacher said that the number line must be drawn with a ruler, and it must be drawn as a regular straight line, otherwise you will be deducted points during the exam." ”

"Okay, okay! You have a point, let's not mention the past, isn't it good to study the current math problems well? Mention what the previous. Fu Feng knocked on his head, he really hated what he said just now, why did he say that sentence just now, was his brain kicked by a donkey?

"Forget it, I still have to fight with me." Nineteen Nian turned his head and said to him.

Fufeng picked up the pen and knocked on the head of the melon, reminding her, "Hurry up and open the book, don't waste time, do you still want to learn skateboarding, I'll take you to learn skateboarding after finishing this chapter of the test paper." ”

"Really?" As soon as she heard about learning to skateboard, Nineteen Nian's eyes lit up, and she asked him many questions at once, "When are we going to learn to skateboard?" When will this chapter end? ”

Fufeng finally woke up, and sure enough, skateboarding was more fun than his math problems.

He picked up the pen again and tapped her forehead.

"When you've learned the first chapter, when are we going to skateboard."

"Oh my God! I'm going to have to learn when to finish it. Nineteen Nian stretched his waist, looked down and saw the dense questions in the test paper, his head was so big.

It felt like her brain was already occupied by the joy of learning to skateboard.

"You'd better study honestly." Fu Feng turned the pen, "Don't let the joy of skateboarding take up too much of your study time. ”

"Hey, I want to skateboard for a while." Nineteen Nian lay helplessly on the table.

Fufeng rubbed her soft hair and said to her gently, "Study hard, your goal is to score more than 90 points in the college entrance examination." ”

"Isn't it more than eighty points? Why did you go up again? Listening to the score she couldn't even think of, she was helpless.

Fufeng opened the chapter of the number line of the textbook for her, "There are more fixed goals, and there is pressure to be motivated." ”

"This is the formula for the number line, and I used to mark it out. Read it again. Fufeng pointed to the long formula he had sketched with a red pen.

Under his guidance, Nineteen Nian read this boring text.

"Draw a straight line, take any point on this line as the origin, and use this point to represent 0...... This type of straight line, which specifies the origin, the positive direction, and the unit length, is called the number axis. ”

"See, like Figure 1-4, it's called the number line." Fufeng picked up the sketchbook again and put it in front of her, "You draw a number line." ”

Nineteen Nian lowered his head and drew a number line according to his meaning.

He reminded her beside him, "When you encounter a number line when you encounter a solution question during the exam, you will indeed be deducted points if you don't use a ruler, so remember to bring a ruler for tomorrow's exam." ”

"Got it." Before Fufeng could finish speaking, she nodded in agreement and handed her the sketchbook.

"Don't interject next time, I'm talking to you, not to you." Fufeng tapped her forehead again, "Cheer up, don't look like you're asleep, look at the fifth question on the test paper." ”

"Okay." Nineteen Nian looked down at the test paper.

Fufeng borrowed the number axis she had just drawn for her to check.

"Look! This problem compares the size on the number line, you can calculate it like this, a is less than -1, right? Then we can conclude that a is less than b and less than 1, then a+b is less than ......"

Training room in the computer room.

Gu Zijun and Xu Qianyu worked together, immersed themselves in drawing the structure of the clothing, and because of the first practice of pattern making, they always made frequent mistakes.

No, the neckline is slanted again.

"Qianyu, you handed me the eraser, the line on the neckline is crooked." Gu Zijun stretched out his hand and asked Xu Qianyu for an eraser.

Xu Qianyu stretched and yawned, so lazy that he didn't even want to hand her the eraser.

She walked out from the sewing machine, stood in front of the classroom, and looked at the training room of Nuo University, there were only three students left in the class, and even Ren Baifan, who usually walked with them, went home early because he was far away from home.

"Why don't we go home too, I'm really too lazy to make a version, wrong and wrong, it's too difficult." Xu Qianyu had already picked up the eraser, but she didn't plan to hand her the eraser at all.

"Eraser. Eraser! Come on! Gu Zijun, who was immersed in the map, had no intention of going home at all, she reached out to Xu Qianyu to ask for an eraser.

Xu Qianyu threw the eraser to her, and repeated what he had just said, "If you want to draw yourself, I'm going to clean up my things." ”

As she spoke, she had already brought the trash can over to wipe the table and go home.
