Chapter 10: Quiz

Dwarf tables and chairs, clean blackboards, and a very light book smell in the air. For a long time, I didn’t sit in the classroom at 8:00 in the morning, and I missed it.
She smashed a piece of two cents in her heart, stuffed it into the pocket, and looked out the window. The northeast direction is dedicated to alleys, but she can't go to Laolin now, because her current status is to go to school on Xiaolin.
At 8:20, there are only a few talents in the Olympics class.
She swept the classroom, opened the Olympiad textbook, and prepared to preview the content of the lesson in advance, mainly to find the feeling of being a top student.
In the last lesson, I will talk about the first lecture of running a boat. This lesson is about the second lecture of running a boat...
The hand was on the textbook, and the thumb of the book suddenly stopped.
Lin Chaoxi turned two pages forward, and Xiaolin’s classmates wrote something in a twisted font.
1. Complete the first lecture after the boat.
2. Think about the additional question 1.
3. In the next class, send a registration form, you must be admitted!
She cares for her own childish font, and the exclamation mark shines in the sun.
Lin Xiangxi thought, in fact, she was never so aggressive when she was a child.
I have never thought of what I want and what I want to accomplish.
Just sit for a while, until someone sat down beside her, elbows, and smashed her face. She took a nap in her seat, turned her head and saw a puffy child.
The children have large faces and small eyes, like two black beans on the white noodles. At this moment, she was staring at her, as if she had crossed the 38th line between the two desks and she was not finished, especially cute.
Lin smiled and reached on the cheek of the child. There was bruises there, she called yesterday.
Yes, yes, the fifth class of the Red Star Elementary School and her class were selected by Lu Zhihao, the son of their class teacher, and the first enemy of Xiaolin’s day.
She smiled and said hello: "Lu Zhihao, you are coming."
Lu Zhihao’s children took a quick shot and opened her hand:
You are sick!

"Nervous disease, hit you do not break the law." Lin eve quietly finished, turned his head and turned the book.
"There is no aunt's neuropathy!" Lu Zhihao frowned, and yelled at her.
The classroom suddenly calmed down.
"Lu Zhihao!" On the podium, the face of the female teacher who just entered the door was white.
Lin dynasty also looked up suddenly. She originally wanted to tease Lu Zhihao, but she did not expect to be actually entered by the mother of Xiaolu.
Lu Zhihao’s mother, Xu, brushed down the textbooks, and piled up the workbooks in her arms, stepping on the high heels and walking to the table.
Lin Zhaoxi estimated that if it was at home, then Xiaolu’s had already blossomed. However, in the classroom, Xu also has to give his son a face.
"And Lin apologizes." Xu teacher looked cold and extremely serious.
Lu Zhihao was shocked by his mother, and his eyes were red. He was reluctant to turn his head and twitched: "I am sorry..."
"The life experience of other students is not the reason you attacked her." Teacher Xu finally said, as if to the rest of the class.
Lin Chaoxi licked her lips. In fact, when she was told by Lu Zhihao, she was still a little uncomfortable.
But now it will not be at all.
......
The content of this lesson is the second lecture of the boat. The core of all the problems of running water is two formulas.
Water speed = ship speed + water speed
Reverse water speed = ship speed - water speed
Teacher Xu said these contents on the podium. Lin Chaoxi learned it ten years ago. At that time, she felt that the content of this lesson was not simple. The speed of the water in the water was particularly high, but she could learn it again now. She felt too clear. This is not to say that her intellectual level is much better than the fifth grade of primary school, but the ability to understand problems is different.
v ship = (v cis + v inverse) / 2
v water = (v cis - v inverse) / 2
Looking at the contents of the blackboard, Lin Chaoxi also copied it.
"v ship =..."
Before she finished copying half of the formula, the smooth adult font on the thin face made her feel excited. The words of the fifth grade girl are written like this, and must be the true disciple of Pang Zhonghua. She rushed to change her left hand and copied the formula written by the teacher on the blackboard.
Lu Zhihao's child is a right-hander. The right elbow is tied with her left hand. Two words are written so that they are both uncomfortable.
However, it was probably the mother who had been lectured on the stage. Although Xiao Lu’s face was uncomfortable, he was very eager to swallow and was hit by a typo. He took a rubber eraser and vented it.
There is no way for Lin Chaoxi, but I can only try to shrink it in the corner.
Finally, it is estimated that I really can't stand the situation of being hit by writing two words. Xiao Lu’s classmates put down the pen, and the black beans’ small eyes were exactly the same, and his attitude towards his mother’s book was exactly the same.
"Why do you suddenly change hands, so many things!"
Because my words are too good to watch you afraid.
Lin Chaoxi thought silently.
But before she could find a good reason, she listened to Lu Zhihao’s domineering and said: "The next class changes position, I sit inside!"
Lin Chaoxi couldn't refuse. He could only look at the face of Xiao Lu's white-headed girl. He almost couldn't hold back and pinch the meat on his face.
However, this time, they still have no chance to change seats.
During the break, Xu put a piece of chalk and said, "Students, we use the ten minutes between classes and the first five minutes of the next class. Let's do a quiz."
Other classmates in the class complained. Lin turned to a circle pen, and did not take the test for a long time, but she felt excited.
The test paper was sent down very quickly. It was a thin and brittle a4 paper. Xu was well prepared and had already printed the test paper in advance.
There are a total of ten application questions on the test paper, but the test time is only fifteen minutes. This means that the time to complete each question is only one and a half minutes, which is a test of the speed of thinking and the accuracy of the calculation.
Lin Chaoxi looked at each topic roughly.
Ten application questions.
Three questions "The principle of tolerance"
Three questions "Cattle grazing"
Three questions "flowing water boat"
There is also an additional question related to the last boat, which is just the content of the new teaching, but it has nothing to do with the content of the new teaching.
In the class, there was only the rustling sound of the question. Lin was thinking for a while, but she actually had some trouble now.
It’s not that I won’t do it, but I will do it too.
After more than ten years of formal mathematics exam training, she saw that these basic questions already have inertial thinking. In other words, she has more advanced tools, but how to solve problems with simpler primary formulas, her ability in this area may not be as good as Xiaolin.
She began to try to think less and think slowly. After seven or eight minutes, she did three things.
At this time, the Olympus teacher who had been walking around in the classroom spoke up: "Be careful and detailed, the next week is the summer camp's selection test. You can enter the summer camp, which means you are closer to the Xiaogao Olympic team champion. step!"
Lin Zhaoxi felt that this "one step" spanned a bit.
The Xiaogao Group refers to the fifth and sixth grades of elementary school. The number of primary and secondary school students in the city adds up to more than 100,000. Only five people can participate in the peaceful participation.
There was a lot of selection before that.
10 students from each school participated in the
Summer Camp Selection Test
. There are only 50 places in the summer camp. According to the elimination system, there are 5 people left, representing the city of Anning to participate in the provincial competition with the city as the participating unit.
The total score of 5 people is the total score of the group.
Now, even if they have not passed the school-level selection, the teacher is already looking at the provincial champions for them. This cake is too big. What's more, the level of mathematics education in Anning City is actually not very strong. It is not in the province. Is this suddenly a sword?
When I think of it, the teacher will automatically explain it to them: "I will say that, there is an absolutely talented primary school student next door. It is a total score. This time, the first group of the Jin Cup is sure to be safe."
When she spoke, she automatically passed by Lin Chaoxi. Lin Chaoxi’s heartbeat was shot again and she remembered the name.
"Who is the teacher?" Someone asked.
"Zhang Liang, you should know someone."
Lin Yixi's pen tip, slammed his head and looked at the Olympics teacher who communicated with the students.
There are really people "oh oh oh", "he is super powerful"...
Lin Chaoxi was in a mess.
If there is no big mistake in the two worlds, if she remembers nothing wrong. Then in September of this year, Yan Zhi took the individual champion of the whole game.
And Zhang Liang?
Lin Zhaoxi remembers Zhang Liang. I can really say that I am smart, but how can it be said that the wind is overwhelmed?
She thought a lot about it, until the teacher of Olympus gave her a slap in the morning, so that she would wake up: "Every time you take the test, you must record the total score. Don't think that each of you can go to the selection test next door. You only have 10 in it. Individuals can go to the place."

Next door
refers to an experimental primary school separated by a street. Lin Chaoxi knocked his head with a pencil. How much does Xiaolin care about the Jin Cup, how much he wants to enter the summer camp. She is clearer than anyone else.
Before Xiaolin’s study was serious, people were also smart. Every time they took the test, they scored well. The total score is very high. It is very hopeful to represent the school to the primary school to participate in the Jinbei Summer Camp. Dean's mother has always been proud, and even many children in the hospital know this and take her as an idol.
Now...
Lin Chaoxi squinted at Xiaolu’s classmates who had finished the five-faced scroll and then looked at their own.
She carefully grasped the pen, woke up, sighed, and no longer wanted to swear. I have already escaped from school and I am not happy. This time, she really does not want to see the disappointment of the Dean’s mother. 2k novel reading network
