Shen Xinyu let go of Gu Ningheng's hand with a smile and ran to Xi Yanxia, "Brother." Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info remember my milk tea. The first and second classes of high school. ”

Xi Yanxia smiled with satisfaction and made an OK gesture.

Gu Ningheng's gaze turned twice on Xi Yanxia. Something suddenly occurred to her.

Xi Yanxia hooked the corners of her mouth and looked at Gu Ningheng, "What is Sister Heng looking at?" ”

The corners of Gu Ningheng's mouth curved into a beautiful arc, "Xi Yanxia." You should study hard with your brother. Be sure to take the test! Otherwise......" Gu Ningheng wrapped his wrist around, with a little smugness in his smile.

Xi Yanxia, who was watching it, was itching in her heart, "Sister Heng, you won't be eating your sister's vinegar, right?" ”

Gu Ningheng raised his eyebrows and smiled lightly, taking it for granted, "I'm reducing the burden for myself." ”

"I can't do it alone, you four." Gu Ningheng's eyebrows curled, "This is called rational use of resources." ”

Xi Yanxia watched Gu Ningheng pat him on the shoulder and walked into the classroom, the smile on his mouth getting bigger and bigger.

Is this called duplicity?

Xie Jin stood next to Xi Yanxia with a thoughtful look, "One person tutors four, and more than one tutor." She does get tired. ”

Xi Yanxia turned his head to look at him.

But seeing Xie Jin muttering to himself, "It seems that I still want to join forces with Su Zimo to reduce some of Brother Heng's burden." Tibu walked into the class.

Xi Yanxia pouted slightly.

All right. can't let his sister Heng be too tired.

"Sister Heng, I've decided." Xi Yanxia also walked in, "I'll go and study with my brother, and then get to the top two hundred for you to win glory!" ”

Gu Ningheng stretched out his hand and patted Xi Yanxia's face, and said with a smile: "It's so good." ”

Then he handed the sorted out page numbers of the real and virtual words to Xi Yanxia, "Remember to memorize it." ”

..............................

Xi Yanyu is very quiet today.

It's been quiet since last night's math paper came out.

He scored 107 and 82 for second place in the first class.

But Gu Ningheng took the 131 exam.

Xi Yanyu also doesn't know whether his current mood is jealousy or inferiority. It's also like neither.

He's quite calm.

I can even remember Gu Ningheng's expression of disbelief after seeing the scroll.

At that time, he thought that Gu Ningheng would not do this.

In retrospect, it was more like the surprise of seeing these mathematical theorems where they shouldn't be.

She is no stranger to these theorems.

Xi Yanyu's gaze fell on his test paper. He basically didn't score any of the three major questions in the second half.

Although there was no eye-catching red cross on the roll, there were only one or two points behind the plus sign, which made Xi Yanyu can't help but purse the corners of his mouth.

Unwilling.

Obviously he studied all summer long.

Obviously, he has already begun to learn permutations and combinations in the second year of high school, and only the probability of the last big chapter is left.

But he still lost to Gu Ningheng.

There is always the embarrassment that the effort is not proportional to the reward.

And.

Yan Xia said that he hadn't seen Gu Ningheng listen well in class.

Then why did he lose to her?!

Why lose to her?!

Is it really because of her own luck?!

Xi Yanyu stood up suddenly.

Li Meng next to him was taken aback. The students around looked up at Xi Yanyu, who was "standing out from the crowd".

Li Meng pulled Xi Yanyu's clothes, "Yan Yu." Sit down. ”

Xi Yanyu glanced at the wall clock on the blackboard. Sit down as you say.

Just start packing up.

There are still six minutes left to finish the evening self-study.

He was going to Gu Ningheng to ask for an understanding!

..................................

"Jingle bell—"

The bell rang for the end of the evening self-study class, Gu Ningheng put away the materials she had printed out at Gu's father's school before, patted Xie Jin to turn him around, and looked at Sun Tongtong again, "Are you all done?" Naturally, he turned his head to Xi Yanxia and Su Zimo, and said the same.

Although there are a lot of homework in the first year of high school, after all, the progress of the first year of high school science and the third subject is not fast, and the third subject of liberal arts is the kind of workbook that does not even receive answers. Only the three major subjects will have relatively more homework. If the evening self-study is not wasted, in fact, at most the second evening self-study can be done before the end of class.

Now Gu Ningheng is looking for four people to ask for math problems, which she deliberately found when she was doing her homework. As a reborn party, coupled with the skill of learning a book overnight in college, Gu Ningheng's focus on high school mathematics can be discovered almost once.

"It's done." Everyone nodded.

"Then let's all come around." Gu Ningheng greeted everyone. The answer was reported directly.

Of course, this answer was made by Gu Ningheng himself. She can still guarantee this accuracy.

Luo Anqi, who was originally planning to rub around here for a while, heard that Gu Ningheng's method of giving them four "small stoves" turned out to be the answer, and suddenly the movements in his hands became faster, and he packed up his things and left the classroom in three clicks.

When I went out, I saw Xi Yanyu at the back door.

Luo Anqi knew him. After all, the first grade came to Gu Ningheng again. is still Xi Yanxia's brother.

Luo Anqi thought about it and walked in front of Xi Yanyu, "I said it for your own good." You'd better hurry up and bring Xi Yanxia home. Gu Ningheng is giving them the answer. ”

When Xi Yanyu heard this, his brows furrowed slightly. Report the answer? What does Gu Ningheng want to do? He walked towards the sixth class.

Luo Anqi watched Xi Yanyu walk in, and turned around to go home with peace of mind.

Gu Ningheng happened to be reporting the answer to the last question. "This question is C, which of you is wrong?"

Sun Tongtong and Xi Yanxia silently raised their hands.

Xi Yanyu stopped.

Gu Ningheng unexpectedly didn't say anything, not even an explanation of why he chose C.

Xi Yanyu's eyebrows sank slightly. Is it really just an answer? Step forward.

But I heard Gu Ningheng's voice, "Let's look at it from the beginning." Tell me the first question, what is this question for? ”

Sun Tongtong whispered, "Assemble." ”

Gu Ningheng: "What is the collection?" The collection is too extensive. ”

Xi Yanxia glanced at it and said, "Elemental." ”

Gu Ningheng: "A little more detailed." ”

Su Zimo continued: "The test is the nature of the elements. ”

Gu Ningheng: "There is more than one nature of the collective element. ”

Xie Jin finally said, "The reciprocity of the elements. ”

Gu Ningheng nodded, pointed to the question and said, "It is true that I have tested the heterogeneity, and I have also tested the disorder. So you solved x=1 and y=5 earlier, but the total number of sets is only 3 instead of 4. Because the two sets of a and b are just in different order of numbers. They are the same collection. ”

Xi Yanyu stood behind the five people and listened for a while, but the emotions in his eyes became more and more complicated.

He understood what Gu Ningheng was doing.

But that's where his emotions come in.

Gu Ningheng said that he was giving them a lecture, but in fact, he was guiding the four of them to clarify the test points of the questions.

From beginning to end, Xi Yanyu didn't hear Gu Ningheng explain the steps of solving the questions in detail, and only heard the remaining four people being guided by the girl to discover the test points for each question. And each question is very meaningful.

He Xi Yanyu will also give lectures to others, but he always focuses on explaining the steps.

It is better to teach a man to fish than to teach him to fish.

And he's the one who gives the fish.
