Chapter 3

After the test paper was handed out, the students quickly wrote their names and filled in the answer sheet. They wanted to finish the multiple-choice questions in the fastest time.

In the quiet classroom, there was only the rustling sound of students doing questions and the swaying sound of fans.

Outside the window, one or two birds were shouting on the branches, as if cheering on these junior high school students.

But some students are not included.

During the whole examination, long Jiayang was like a withered stray dog on the street. He scratched his head from time to time, stretched his neck and glanced at the test paper in the upper right corner.

Unlike long Jiayang, Xu Zijun had long given up this thorough examination and lay on the table looking for Duke Zhou to play chess.

All this was seen by the math teacher.

The math teacher's name is Wu Lin, an old teacher who has been working for more than ten years.

During the exam, he glanced over and found that the students in the front row were actively answering.

The students in the back row are "actively dozing off".

Mr. Wu Lin also knows that the third and eighth line of classroom performance is related to seats. It has been gradually formed since the first semester of the second day of junior high school, and the polarization is becoming more and more serious.

In addition, there are still 100 days before the middle school entrance examination, so Wu Lin is too lazy to urge those poor students who take the examination. If you have this Kung Fu, you might as well pay more attention to the students under the middle level.

But in the process of invigilating the exam, he found that Li Hao, who always handed in the blank paper, was "writing hard"?

This surprised him.

Wu Lin stepped down and walked towards Li Hao's seat.

He frowned slightly when he saw the answer card written by Li Hao.

Did you do the last question?!

And there were three small questions in the last big question, and he did two small questions right!

For some excellent students, even the second question may not be done, but a poor student did it!

"Is it cheating?"

Wu Lin subconsciously thought of this, but soon he denied it.

Because these questions were as like as two peas, and the reference books could not find the same original questions.

Li Hao was immersed in thinking about the problem and didn't realize that the math teacher was right next to him. At the moment, he had only one idea in his mind:

[Wu Lin is a man. He always corrects these problems in the underworld, which makes me have a shadow on mathematics before.]

"Jingling!"

When the bell rang after class, everyone was relieved.

Mr. Wu Lin asked the group leaders to put away the test papers of each group.

"Classmate Li Hao, we're going to wind up."

The group in charge of Li Hao's winding up is a quiet girl with glasses. When she came to Li Hao, she found that he was still writing the test paper.

"Soon, soon, I'm almost finished."

Li Hao is still stuck in the third small question of the last big question.

Long Jiayang looked at the answer card written by Li Hao and was surprised and speechless.

"Sleeping trough, brother Hao, you have written the last question? Have you hung up today?"

His cry made half the class look in the direction of Li Hao.

Li Hao wanted to scold the two fools. There was no way. He had to hand in his test paper in full view of the public.

"Liberation, brother Hao, go and play."

Long Jiayang packed up his schoolbag, pretended to be haggard and said, "Alas, kaokaokao, the teacher's magic weapon, points, students' lifeblood, my lifeblood is gone, so I want to go to the court to find my confidence."

Li Hao shook his head and said, "no, I have to recite politics again. Go."

Long Jiayang couldn't understand Li Hao's strange behavior today.

Said a salted fish, but you began to struggle?

Thinking of this, he also put down his schoolbag and took out a book "five-year high school entrance examination, three-year simulation", sighing: "brother, as a teammate fighting side by side, how can I abandon you."

Li Hao thought he also aroused interest in learning.

But who knows, ten minutes later, there was a snore next to him.

Li Hao smiled bitterly and thought that maybe studying is really not long Jiayang's talent.

"Then let him place his hopes on the next generation."

Li Hao understands that there are still 100 days before the middle school entrance examination. He must raise the score of the subject of memory examination.

You only need to go through the contents of the book, then these contents can be remembered.

As for thinking ability subjects such as mathematics and physics, it takes a lot of time to brush questions.

"Still have to work hard!"

Just as Li Hao was about to take out political materials to recite, a girl came to him.

"Classmate Li Hao, can you answer the penultimate math question just now?"

Li Hao looked up at the girl in front of him, and his memory poured out.

Her name is Liu Xiuyuan. She is the representative of the mathematics class in the class. Her grades are very good and she is deeply loved by teachers and students.

In junior high school, almost all girls had short hair.

Although it is the same, Liu Xiuyuan's temperament is enough to stand out among many girls, and with her beautiful appearance, she must become the flower of a department after going to college.

Li Hao was surprised by Liu Xiuyuan's question.

After all, in everyone's eyes, he is a poor student!

A student who is willing to do anything but not study.

Li Hao took out the test paper in the drawer, opened the other side and prepared to tell the geometry problem of the penultimate problem.

But I didn't expect another voice to come.

"Xiuyuan, which question can't you?"

Listening to his voice, Li Hao recalled that he was also a Xueba, named Ji Mingcheng.

He remembered that Ji Mingcheng seemed to like Liu Xiuyuan from the beginning of junior high school and had a secret love for three years.

So when Liu Xiuyuan asked Li Hao about math problems, Ji Mingcheng was so nervous.

Li Hao wanted to do a favor and let Ji Mingcheng solve it. He said, "why don't you let Mingcheng tell you this problem? He will."

When Liu Xiuyuan heard this sentence, she stopped talking and wanted to say something, but she acquiesced in the end.

Ji Mingcheng was very happy. He nodded and said, "Xiuyuan, let me tell you, Li Hao, he won't."

Li Hao heard this sentence without any expression, but chose to continue to do the question.

Ji Mingcheng read and analyzed the question to Liu Xiuyuan: "you see, as shown in the figure, in the rectangular ABCD, e is the midpoint of CD, be ⊥ AC is in F, over F is FG ∥ AB is in G..."

"Now verify that Ag ^ 2 = AF ・ FC. Obviously, we need to draw two auxiliary lines first..."

Liu Xiuyuan frowned when she heard this: "do you want to draw two?"

"Yes." Ji Mingcheng nodded. "This problem is difficult, so it's normal for you not to do it. Don't worry, I'll teach you. Look at these two triangles..."

At this time, Li Hao suddenly interrupted, "don't be so troublesome."

"What?" Ji Mingcheng was stunned and looked up at Li Hao. His expression seemed to mean "can you answer this question?".

Li Hao picked up his pen and wrote directly on the draft paper: "you first prove that RT △ ade ≌ RT △ BCE, so AE = be, and then push down to get Ag = BF."

"After the conditions are established, prove RT △ BFC ≌ RT △ AFB, and finally get Ag ^ 2 = AF ・ FC."

After simply drawing two similar triangles, Li Hao shrugged and said, "it's so simple to prove twice congruence and then similar."

After all, Liu Xiuyuan is the representative of mathematics class. After Li Hao's analysis, she was impressed at once.

"You're great! Classmate Li Hao." Liu Xiuyuan showed an incredible expression on her face.

Li Hao calmly picked up his schoolbag and got up and said, "this topic has the same type of topic in May third. Go and find it. I'll go first."

"OK! Can you teach me the last big question tomorrow?" Liu Xiuyuan asked with a little uneasiness.

"It should be OK." Li Hao waved and left through the back door.

Only Ji Mingcheng's doubts were left.

Didn't you agree to let me teach you?

And... This question is so simple?
