At that time, the questions were not difficult to take the university entrance examination. The reason is that there were no textbooks at that time, and the results of the college entrance examination were far worse than now.

Even so, it was very difficult to get into a university at that time, after all, it was a test without textbooks. For example, Du Mengning, who can be admitted to sixty-eight, is a scholar.

But in front of Li Mo, these people are basically scum!

"When have you been spitting out wild words!?"

"yes, what's going on with that?"

No one believes that anyone else can do this, at least you won't find anyone like this in Hejian Township.

Li Mo stood in front of the blackboard with a chalk, and he turned his face sideways to look at Xiong Weiguo.

"What am I doing?

The corners of Li Mo's mouth twitched slightly and asked, "Are you ready for thirty yuan?" What will you do if I answer this?"

"I'll give you sixty!"

"That's right!"

Li Mo saw that Xiong Weiguo was full of confidence, he didn't hold back himself, and burst out laughing. Then cover your mouth with a chalk in one hand and brush on the blackboard to draw a picture.

The people below were all pointing, and no one expected Li Mo to draw it.

"There are two brushes!"

"There's a fart, it's just a drawing, our squad leader can draw with his eyes closed!"

Li Mo then took a deep breath, and then said with a confident smile: "It's time to perform the real technique......

Li Mo's hand quickly wrote a bracket on the blackboard. Then he began his proof process with a beaming smile!

(I.) Proof: Connect CB, OC,

∵CH⊥AB，DB⊥AB，

∴CH // BD，

∴ＥＨ／ＢＦ＝ＡＥ／ＡＦ＝ＣＥ／ＦＤ，

∵HE＝EC，∴BF＝FD

∵ AB is the diameter, ∴∠ACB=90°∴∠BCD=90°,

∴∠BCF=∠CBF=90°-∠CBA=∠CAB=∠ACO

∵∠ACB=90°∴∠OCF=90°, ∴CG is the tangent of ⊙O.

When Li Mo's chalk drew the last period, the students below who read the neat board calligraphy looked stupid.

Li Mo's board book is definitely much stronger than the teacher, and he doesn't have any jams at all throughout the whole process!

Xiong Weiguo's face was pale, he really didn't expect Li Mo to solve the first question!

Li Mo smiled evilly and said, "This is thirty yuan, right?"

"You're going to have to answer them all! And you don't know if you're right!"

"Hmph, don't you know if I'm right? Since you don't see the coffin, you don't cry...... Great!"

Li Mo continued to write......

(II.) obtained from FC=FB=FE: ∠FCE=∠FEC,

∠ＥＡＨ＝９０°－∠ＡＥＨ＝９０°－∠ＦＥＣ，

and ∠G=90°-∠ECF

Get: ∠EAH=∠G So FA=FG, and AB=BG

From the cutting line theorem: (2+FG)2=BG×AG=2BG2 ...... ①

In Rt△BGF, the Pythagorean theorem is obtained: BG2=FG2-BF2 ...... ②

From (1) and (2), FG2-4FG-12=0, solution: FG=6 or FG=-2 (rounded)

∴AB=BG=4 times root number 2

The radius of ∴⊙O is 2 times the root number 2

Li Mo finished writing bits and pieces at the end, and he put the last chalk head down in Xiong Weiguo's hand in a dashing manner.

"Learn without limit, and don't be ashamed to ask. ”

Li Mo was so arrogant that at what time of his words, Xiong Weiguo, who was angry, trembled.

Li Mo snorted coldly, and then stretched out his hand.

"What are you doing?"

"Can't afford to play?"

Li Mo really doesn't look down on Xiong Weiguo, so he can slap him in the face and never raise his noble hand.

Xiong Weiguo gritted his teeth, he squeezed out a sentence from between his teeth and asked, "Don't go too far!"

"Oh! I can't afford to play!?"

"Oh!!!

"Teacher Xiong can't afford to play!"

At this time, the students in the room began to collectively coax, Xiong Weiguo's face had turned the color of pig liver, and he was rich. But the money he saved up to buy a bicycle.

"Okay! I'll give it! Don't think I can't afford to play! But Li Mo, you wait for me!"

Xiong Weiguo grabbed a roll of money from his trouser pocket and strangled it with a holster.

This money is what he saved to buy a bicycle.

Who would have thought that it would be given to Li Mo today!

Li Mo was even more ruthless that he actually counted the money in front of Xiong Weiguo!!

This can be regarded as slapping Xiong Weiguo in the face!

"Seventy-six, fourteen short. ”

Li Mo stretched out his hand again, looked at Xiong Weiguo and smiled.

Xiong Weiguo said with a dark face: "I owe it first, I will pay you this month!"

Li Mo sighed, and then after accepting Seventy-six, he took the paper and pen from the table and said, "Come on, I'll write you a receipt, you write an IOU, and you have to pay me back the interest." Two cents a month, isn't it? That's the basic rule, right? That is, you have to give me three cents of interest money this month. ”

"You're poor and crazy?!! you want three points?"

Li Mo's experience suddenly cooled down, and two cold lights like blades shot out of his eyes

"Have you ever been poor? Have you been hungry? Have you watched your sister go hungry and have no way to help her? If not, shut up. ”

Li Mo's expression was so frightened that Xiong Weiguo didn't dare to refute, and when Li Mo turned his face to look at Teacher Dong, he returned to his seat with a smile as if he was fine.

After Teacher Dong looked at it, she nodded with satisfaction and said, "All right." ”

After Li Mo sat down, he didn't say a word.

It looks like an old monk who has settled down, but in fact he is sleepy and wants to sleep.

Xiong Weiguo turned around and left the classroom with a dark face, and Teacher Dong continued to look at the big guy and began to talk about the topic.

Li Mo lay on the table and fell asleep.

Teacher Dong didn't call him, because Zhang Qiang came just now and told Teacher Dong about Li Mo's situation, their family suddenly changed dramatically, and the house was burned. And Li Mo's injuries are very serious now.

It's normal for Li Mo to be sleepy, there are so many things going on these days, if the house hadn't been burned, he would still be recuperating.

So Teacher Dong didn't disturb him to sleep.

It wasn't until the end of class that Li Mo sat up groggily, he rubbed his eyes, and saw that it was not early. It's time to find a place to eat.

Li Mo walked out of the door and saw many girls at the school gate. Everyone surrounded Xiong Weiguo. Li Mo walked out, and suddenly someone shouted Li Mo.

"Li Mo?!"

Li Mohu turned his head suspiciously and found that it was Zhang Jiajia. She is also good at studying, she is from Baihe Village, and she is also a fellow countryman, and she is a distant relative of Zhang Ruyi.

Zhang Jiajia looks good, although she is not as beautiful as Du Mengning, but she has a round face and two dimples when she laughs. Fair skin. The cosmetics of a little girl in this era are at most a box of alabaster.

"Something?"

Li Mo stopped, and Zhang Jiajia followed him in a few steps and said, "Can you go out with me?" ”

"Me?" Li Mo looked at Zhang Jiajia behind him suspiciously, he didn't quite understand what this girl meant?

Wouldn't it be interesting to yourself, would you?

"Okay!"

Li Mo agreed, and Zhang Jiajia followed Li Mo all the way out, talking and laughing.

"Zhang Jiajia, why are you going? I'll take you?"

may still be unconvinced, Xiong Weiguo saw Li Mo and Zhang Jiajia walking together, and immediately called Zhang Jiajia, and patted his car seat.

"No need Teacher Xiong, I'll go with Li Mo. ”

"What's polite, I'll send you! Come on, come on! You have to walk with him, how comfortable it is to take the car, do you think he has a car?"

Xiong Weiguo was mocking, and Li Mo took out the car keys.

He didn't speak, but Xiong Weiguo also shut up......

Li Mo shook the key, and then slowly walked to his own car.

The brand-new car lock popped open, and Li Mo looked at Zhang Jiajia and said, "Let's go!?"

"Teacher, I'm leaving!" Zhang Jiajia bowed to Xiong Weiguo, and then staggered behind Li Mo.

Li Mo took Zhang Jiajia with her, and many girls looked at her with envy.

That's a new car! And it's a big permanent!

"I'll go, when did Li Mo become so rich?

"yes, Da Yong, this is too rich, right?"

"It seems that people are not as simple as changing clothes, they are really rich. ”

"I guess there's something good going on at home!"

The girls of that era did not have the term nymphomaniac, but they also envied a good life. Especially many girls actually have to talk about marriage after leaving high school, and they will also go to have a good exchange when they meet a good guy. Although she was very conservative at that time, the girl's attitude towards her family was also very direct.

Li Mo took Zhang Jiajia out of the school gate, and many people looked at Zhang Jiajia with envy.

There are also many boys who envy Li Mo, after all, Zhang Jiajia is also a very beautiful girl. Li Mo sent her to the door of the post office, and Zhang Jiajia blushed and whispered, "Thank you." ”

"Go inside, I have some things to do. Can I go back?"

"Well, of course. But I still want to thank you, classmate Li Mo!"

Zhang Jiajia entered the post office with a red face, and Li Mo pushed the cart and wanted to leave. As a result, a group of children were heard to be in a hurry.

"Oh oh, pick up the rag old woman, pick up the leaves every day. ”

Li Mo frowned, he pushed the cart and walked that way, and saw an old lady with a basket and crutches being surrounded and teased by a group of children, she blushed and waved a stick to chase those children.

The children also threw stones at her, and Li Mo couldn't help but see this situation.

"What are you doing! How do you bully the old man?!"

Li Mo's roar, coupled with the uniform riding a bicycle, the children heard it and someone immediately shouted: "The militia is coming, run!"

The children ran away, and the old lady was left. Li Mo hurriedly walked over, he stopped the car and asked, "Auntie, are you okay?"

"It's all right, young man, you're busy with your business, leave me alone. ”

"Why are your legs and feet still coming out, and what about your children?"

When the old man heard this, his eyes turned obviously red. Li Mo felt that he had said the wrong thing, and he was busy apologizing.

"I'm sorry Auntie, I said the wrong thing. ”

The old man waved his hand, and she sighed, "It's not your fault, what are you sorry for? Go ahead and be busy, leave me alone." ”

But as soon as the old man finished saying this, he sat on the ground with his legs limp.

Today, I am afraid that few people dare to help, but in that era, there were still very few such people.

Li Mo hurriedly went up to help her up, and said worriedly: "Auntie, are you okay?!"

"It's nothing, it's just a little dizzy!" The old man held his forehead, and Li Mo felt it, she was not a little dizzy, she was very dizzy!

And I'm hungry!
