She is A and Sa at the same table

Chapter 230 Half of My Heart Is About You (Two in One)

"The third party who intervenes between Jing Xing and Nuomi Tuan—whether male or female, will die."

"..."

Lin Qingyou's eyelids twitched unconsciously, and after a while, she said as tactfully as possible: "I think it's better to stop the support team, I like to keep a low profile."

As if afraid that he would really hold on to the question about the support group banner, she quickly changed the subject and said, "Do you remember that I asked you a question before?"

Jing Xing: "Huh?"

Lin Qingyou: "It was the holiday before, when we went to the playground, didn't I ask you why you didn't want to find a girlfriend? I still remember your sonorous and forceful sentence, it's too troublesome."

She looked at him with her head propped up, her eyes narrowed, and she said, "Why, don't you bother now?"

Hearing this, Jing Xing smiled softly.

Tsk, Xiao Nuomi Duanzi praised him for his good memory before, but now it seems that Xiao Nuomi Duanzi's memory is not bad, how long has it been, and she still remembers it so clearly.

"Then do you still remember your answer at that time?" Jing Xing replied slowly.

Jing Xing thought of the deafening phrase "I am the motherland, the future is the hope of the nation", and still felt that Xiao Nuomi Duanzi's level of thinking awareness was unprecedented.

"Are you an excellent successor to socialism?" he asked her with a smile.

"Of course." Lin Qingyou nodded and said seriously, "I want to study for the rise of China. I have such a heavy task on my back. Even if I fall in love, I can't delay my contribution to socialism."

"I already know that what you pretend to be in your heart is you and your motherland." Jing Xing raised his hand to pinch her soft face, and said narrowly, "Then where am I?"

Lin Qingyou blinked, and replied calmly: "It's also in my heart. Half of my heart is about you and the other half is about the country."

Yes, Not Bad.

Textbook-level answers.

While falling in love, you can not forget to study hard and serve the motherland, which can be called a model for our generation.

After discussing the issue of family, country, world and children's personal relationship, Lin Qingyou's heart of "I love studying, and studying also loves me" came back, and she grabbed his hand and pressed it on the draft paper, fully showing that she is a school bully The literacy that should be in the body - don't forget to study at the same time.

"In order for us to better build socialism and become an outstanding contemporary new youth, please advise us, the squad leader."

Jing Xing rubbed the top of her hair with a smile, then picked up the carbon pen, he had seen the few lines she wrote in the notebook just now, so he continued to follow her steps: "Look here , haven’t you already written that AC is perpendicular to plane PAB, so continue to look at this angle APC.”

His pen tip clicked on the apex of the pyramid, and said: "Take the midpoint G of BC and connect AG, it can be proved that AG is perpendicular to BC, and then take A as the coordinate origin, and the lines where AG, AD, and AP are located are respectively on the x-axis The y-axis and the z-axis establish this space Cartesian coordinate system Axyz."

Lin Qingyou's thinking was opened by the Cartesian coordinate system of this space. While writing with a pencil on the figure he drew, he continued thinking: "So based on this coordinate, let the normal vector n of the plane PBE be set to n=( x, y, z), and then list the associated formula, enter y equal to 3, find the normal vector, and then look at the cosine of the dihedral angle?"

Jing Xing rubbed her head in relief: "A child can be taught."

It's easy to understand, no need to say much, teachers like this kind of smart students, and it's easy to teach.

Lin Qingyou brought the draft paper over, and re-standardized the steps of solving the problem with the square cone on it. As expected, it really belonged to the finale problem. A third small question with writing and drawing took a whole page. Scratch paper.

After finishing the last stroke, she closed the pen cap and breathed a sigh of relief. The draft paper in front of her was picked up before she fully let go.

Lin Qingyou was stunned for a moment, then raised her head subconsciously, and saw Lao Xu's smiling face like a Maitreya Buddha: "...Teacher?"

Old Xu was obviously very satisfied with her answer. While looking at the steps of solving the problem on the draft paper, he nodded repeatedly and said, "Not bad, classmate Lin, this problem is solved well, and the steps are also written in a very standardized way. , I was still wondering if it would be too superficial for you to do this question, but now it seems that I think too much."

Hearing what he said, Du Mingyu and Xu Changhao in the front seat silently cast him a look of "Lafayette Xu, can you take a look at us?" Sister Yuzi's ability to do it doesn't mean that other students in the class can do it too. Can it be done?
After all, the level of most of the students in Class [-] is that of the school at the bottom of the crane, especially in mathematics. The names of the people on the grade list are all from Class [-], but they are counted backwards.

Old Xu took a sip of the tea in the thermos cup unhurriedly, and finally moved his eyes away from the draft paper, seeing the seriousness of his staring at the draft paper, as if he really wanted to see a flower from it .

Just admiring the answer is not enough, he happily took the draft paper and passed it from the first row: "Come on, let's take a look at Lin's problem-solving ideas, this is a standard The textbook has the answer, let's see how her steps are different from your own."

"..." The whole class was as quiet as a chicken, and no one answered.

Also see how her steps are different from your own?

Did Lao Xu misunderstand the level of the class he taught? Do they seem to be able to solve this kind of problem?

Old Xu didn't notice the strange atmosphere in the class, and greeted the students in the front row with a very good attitude to pass the answers in turn. He leaned on the podium, drinking tea in a happy mood, while looking at the students below. The classmate passed the answer mechanically and numbly. After passing the answer for half a classroom, he finally remembered what he wanted to do in the back row just now.

Putting the thermos on the desk, Lao Xu took out a crumpled note from his pocket, walked to the back row and handed it to Lin Qingyou.

"Student Lin, this is a note for you." Old Xu said.

Lin Qingyou thought that he had forgotten about it, and was planning to go to the math office to find him after this class, but unexpectedly, this Old Buddha Xu seemed unreliable, but when he asked for leave and let people go In fact, it has shown an unparalleled degree of reliability.

Lin Qingyou glanced at the reason for asking for leave on the leave note - "The water pipe at home is leaking, the house has been flooded, the depth is half a meter, and it needs to be repaired urgently."

Her eyelids twitched slightly, and she still put the slip into her pocket with a grateful heart.
