Time passed quickly, and it was Sunday in the blink of an eye.

Li Tianran's abrasions on his head and arms have already scabbed, and he will be discharged from the hospital in the afternoon after finishing today's hanging bottle.

During this time, in addition to playing hanging bottles, Li Tianran spent most of his leisure time reading books, and learned mathematics first, after all, he had to take exams every week.

At this time, mathematics is called algebra, and later you have to learn geometry.

The mathematics of the first year of junior high school is mainly some unary equations, and the algorithm of this very simple equation has been mastered and cannot be forgotten.

But there are also some formulas for solving problems with column equations, such as the forward and reverse flow problem: downstream velocity = hydrostatic velocity + water velocity, countercurrent velocity = hydrostatic velocity - water velocity.

There is also the issue of commodity prices: profit margin = (selling price - cost) / cost * 100%, and some formulas for calculating perimeter, area, and volume I don't remember.

In particular, the formula for calculating volume has long been forgotten because it is not usually used, and Li Tianran quickly memorized it again. It didn't take long to grasp the content of a chapter.

After doing some exercises and practicing the finished chapter, Li Tianran didn't continue to read the math textbook much, because the school had not yet taken the next course, so Li Tianran was not in a hurry to read it all.

In this week, Li Tianran read and mastered all the subjects in the first year of junior high school, memorized all the things that needed to be memorized, and learned some additional content.

Li Tianran's diligence these days, her mother Zhao Yue saw it in her eyes, and she was very pleased, feeling that her daughter had grown up and knew that she had worked hard, and discussed with her father Li Jianjun to reward Li Tianran.

On Sunday afternoon, after completing the discharge procedures and returning home to settle the things brought back from the hospital, my parents took out a small box wrapped in plastic paper and tied with flowers.

Father Li Jianjun said to Li Tianran, "Xiao Ran, first of all, my parents want to congratulate you on your healthy discharge, and you will go back to school from tomorrow."

You have not forgotten to study hard during this period of hospitalization, and when you grow up, your parents are happy for you, which is a reward for you during this period of time and a gift for being discharged from the hospital, open it and take a look. ”

Li Tianran happily accepted the gift, carefully unpacked it, and opened the box, which was a gray walkman with a shiny plastic shell.

"This Walkman can help you learn English better, and if you make great progress in the midterm exam, Mom and Dad will reward you, and Mom and Dad will buy you whatever you want.

"Thank you Mom and Dad, I will definitely study hard and get into the best university in the future, and I will not disappoint you.

The family had breakfast together, watched TV together after the meal, and went for a walk in the park.

The next day, Monday, at 7 o'clock in the morning, Li Tianran took the shuttle bus of the three mines unified package, and the bus was full of students from the original No. 30 Middle School, and now they are divided into different classes.

Everyone came up to greet Li Tianran warmly, "Li Tianran, you're okay, it's okay now."

Everyone may have heard about Li Tianran's car accident.

"It's okay, it's not serious, it's just a bruise, I'm all fine now, thank you for your concern!" Li Tianran responded to the concern of his classmates.

Li Tianran, who had long forgotten where the class was, secretly poked and poked two steps slower than his friend Li Qian, and came to the classroom smoothly.

Li Qian was a good friend of Li Tianran when he was in junior high school, but later the two were not in the same high school, and at that time, students did not have mobile phones and could not log in to QQ, and they were not in the same school, and they rarely contacted each other.

When he arrived at the classroom, Sun Wei, who was at the same table, greeted Li Tianran warmly, and Li Tianran secretly breathed a sigh of relief in his heart and found a position!

Sun Wei is Li Tianran's tablemate from the first to the third year of junior high school, and he is also the representative of the mathematics class in the class, and he is also a student in the twelfth middle school in primary school.

When the fourth division of the junior high school was in the fast and slow class, Sun Wei went to the fast class, and Li Tianran went to the slow class, so there was no contact.

When he was in junior high school, Li Tianran also had a crush on Sun Wei, but he never had contact with him later, and when he grew up, Li Tianran didn't mix very well, and he never participated in the class reunion of junior high school.

I never saw Sun Wei again after graduating from junior high school, so I don't know what his future holds.

Of course, the current Li Tianran doesn't have any intention of reliving his old dream, he just wants to take the career route of the big heroine and the route of learning to dominate.

"Nail Bell Bell Bell ......" class bell rang, the Chinese exam came in, and Li Tianran couldn't remember what the Chinese teacher's surname was.

In junior high school, I only remember the names of the homeroom teacher Jiang Huiqing and the math teacher Nie Chuanfang, and the other teachers can't seem to remember any of them.

"Class, good teacher!" "Today we are going to talk about Zhu Ziqing's "Back".

This essay tells the story of the author's departure from Nanjing to Peking University, where his father took him to the Pukou train station, took care of him on the train, and bought oranges for him.

What impressed the author the most in his mind was the back of his father climbing up and down the platform when he bought oranges for him.

The author uses simple words to express the father's love for his children in a profound and delicate way, sincerely moving, and shows the father's care and love from ordinary events. ”

After briefly describing the creative background of the back, "The following is read by the students in the first column in the north for us, one person reads a paragraph, let's start!" "The Chinese teacher began to read aloud.

"It's been more than two years since I saw my father, and the last thing I can forget is his back. That winter......"

I remember that in junior high school Chinese class, the Chinese teacher often asked everyone to take turns to read the text, and once it was Li Tianran's turn to read the XX in the textbook in the past......

Li Tianran read it as a fork in the past time......

Everyone burst into laughter, and Li Tianran knew that XX should be pronounced as so-and-so...... Sweat......

A Chinese lesson passed so happily.

During the 10-minute recess, Li Qian shouted that Li Tianran went to the toilet together, and the girls formed many small groups to go to the toilet together.

It's strange that when they were students, few girls would go to the toilet alone, always calling friends and holding hands.

In the second English class, the teacher finished a lesson and there were more than 10 minutes left, and the teacher marked down the passages and dialogues to be recited.

Let everyone memorize in small groups, and after memorization, the group leader will check it after class.

Each pair of the same table plus the back pair of the same table, four people form a team and choose a team leader.

The captain of Li Tianran's group is Xu Jiao, who is a good student in the top 5 in the class.

This time, Li Tianran is not like when he was always lazy when he went to school, he just didn't memorize it, let alone memorize it in class.

Li Tianran cherishes this opportunity to do it all over again, and the dialogues in the textbooks are all memorized.

The third period is math class, the teacher said that tomorrow afternoon's math class will be examined, and the students can't help but get nervous.

In junior high school, there were 4 classes in the morning, 3 in the afternoon, and two evening self-study sessions from 7 to 8:40 in the evening.

Dinner is not eaten at home, it is eaten at the market near the school, and you can also eat in the cafeteria, but the day students go to the market to eat.

At this time, a beef noodle is 2.5 yuan, and a few slices of very thin beef are the kind, and a meat bun is 1.5.

There is also a small shredded potato burrito for 5 cents a piece, the crust fried on the iron plate becomes golden brown, and it is filled with Li Tianran's favorite shredded potatoes, which is called a fragrant.

At this time, his parents gave Li Tianran 3 yuan a day for meals, and Li Tianran could still save one or two yuan a day.

Because Li Tianran's parents did not have the habit of giving their children pocket money, Li Tianran had his own small treasury since junior high school.

Now there are 56 yuan in the small treasury, Li Tianran was also a small money fan when he was a child, and he can save it.

In Tuesday afternoon math class, the math teacher, Ms. Nie, was a female teacher who looked very capable and serious.

Li Tianran remembered Teacher Nie's name for a reason, at that time, Li Tianran didn't listen carefully in class, and the teacher couldn't ask questions and answers, so Teacher Nie punished Li Tianran for standing in class.

At the end of class, Teacher Nie asked Li Tianran to go to her office, and told Li Tianran again, asking Li Tianran if he knew it?

Li Tianran said yes, Teacher Nie said to Li Tianran at the time, the teacher likes you very much, and thinks you are very smart, you must listen to the lecture in the future, don't let the teacher down, you know?

It was the first time that a teacher said to Li Tianran that he liked him, so Li Tianran was very happy at the time, and he was quite surprised that Teacher Nie would say this.

Usually, other teachers think that Li Tianran is very smart at most, but she is very skinny, and she doesn't have to focus on studying, so she doesn't have any extra attention and affection.

It's a pity that Li Tianran didn't know how to work hard at that time, and he was not the kind of child who would be close to the teacher.

is usually naughty and mischievous, and she doesn't listen to classes seriously, and her grades are not good, and then Teacher Nie will not ask questions about her when she slowly goes to class.

But now everything will be different, Li Tianran confidently took the test paper passed from the front seat, picked up the pen and began to answer the questions.

If x+y=6 and xy=7, then what is x²+y² equal to?

Simple! x+y=6, then (x+y)²=36, x²+y²+2xy=36, xy=7, 2xy=14, so x²+y²=36-14=22.

Knowing that the complementary angle of an angle is 3 times the co-angle of this angle, find the degree of this angle.

Answer: If this angle is x, then the complementary angle is 180-x, and the co-angle is 90-x, then (90-x)*3=180-x, x=45, so the degree of this angle is 45.

Li Tianran did all the questions, I don't feel that there are any difficult questions, the main purpose of the weekly exam, the main purpose is to make everyone's foundation more solid, and there will be no problems beyond the outline.

After Li Tianran finished doing it, he checked it carefully, and saw that some students began to hand in the papers one after another, so he also went up to hand in the papers, and returned to his seat to take out the textbooks and continue to study.

After school in the afternoon, Li Tianran, Li Qian, and twins Han Xiuqiong and Han Xiuyao went to the snack street in the market for dinner.

Li Tianran also ate the shredded potato burritos that he used to miss very much. It was delicious and satisfying.

After returning to school, Han Xiuqiong took out the jumping rubber band from the hole in the table, and the four of them were ready to jump the rubber band together.

Li Tianran remembers that from primary school to the second year of junior high school, everyone's after-school life is very rich, jumping rubber bands, playing sandbags, and kicking sandbags in their spare time, which is very happy, and there seem to be few such activities after the third year of junior high school.

In high school, boys can still play basketball during recess, but girls have no activity at all during recess, just chatting and going to the toilet together, which is very boring.

Now that he can regain the happy time of his youth, Li Tianran is particularly actively involved.

Han Xiuqiong and Han Xiuyao's family, Li Qian and Li Tianran's family, scissors baggage hammer, Li Tianran and Li Qian jumped first, Han Xiuqiong Han Xiuyao supported the rubber band, put it behind her, first in the crook of the leg, and then Li Qian started to jump the horse orchid first, and Li Tianran happened to be secretly poked and poked next to him to observe and learn......
