Chapter 54: Promotion

The bright moon hangs in the night sky, giving the entire oasis base a thin halo.
The staff quarters are located on the north side of the base, surrounded by large pine forests and quieter at night. In addition to a small animal with a thick pine needle, a little soft sound.
"Lao Lu, is this road you chose really ok?"
"It should be possible, go directly to Master's back door." Lu Zhihao pulled down his hat and whispered.
"What do you say about us, how do you read a book now like a thief?"
Hanako whispered, but his expression was very happy and his eyes were bright.
Lu Zhihao knows that he is very excited because he is the same.
They went out for two days, and they came back very late. They just pretended to sleep, escaped from the aunt’s aunt’s room, and now sneaked out. In order to catch up with this class at night, he didn't even go to eat KFC, he clamored to come back soon.
The moonlight leaks through the pine needles and is surrounded by very light and light insects.
Not far away, the window reveals a yellow light that is close at hand. They stood with their teachers and their classmates.
Although I can't see the expression, Lu Zhihao feels that everyone is laughing. People have gathered very well and carefully counted, they are almost the last.
"Hurry and fast, can't be late." The flower roll ran away, happy, and the bag was behind his back.
Lu Zhihao followed, he also ran very fast, fresh night winds flowing into the lungs along the mouth, sweet and incomparable.
When, learning mathematics becomes something that is reminiscent of excitement, he does not know.

When they arrived, they ran into Chen Chengcheng from the road.
"You... why are you coming from there?" Chen Chengcheng asked.
"You didn't see the security guard on the road?" Lu Zhihao also asked.
"I haven't seen it."
"Be careful, if you are caught?"
The door was pushed in and the room was warm. Master looked over and Lin sat on the floor and waved at them, smiling very happy.
There are a lot of small pieces of paper on the ground. When they look closely, they have made a lot of chickens and rabbits, and Lu Zhihao can recognize them because every chicken and every rabbit writes "chicken" and "rabbit". .
"Today, let's talk about the application questions! Chicken and rabbit are in the same cage." Lin Chaoxi sat next to him and vacated the position to them. "What did you just catch?"
The hairpin on the girl's head tied to his face, and Lu Zhihao retired: "On the road we saw on the road, the security guard uncle patrolled."
"That is to be careful." Lin asked, "If you are found, how do you say it?"
"Dream!" Hua Juan shouted.
Everyone in the room heard their conversation and laughed together.
After a while, no reminders are needed, and the lectures interrupted by them naturally continue.
Master’s chicken and rabbit cages are somewhat different from what he once heard. On the ground are a lot of papers of rabbits and chickens, chickens with 2 legs and rabbits with 4 legs.
Lao Lin asked: "What do we know now?"
"Chicken and rabbit have a total of 12 heads, 34 legs.
Lao Lin asked: "What is it?"
"There are a total of chickens and rabbits, and they only have one head. Calculating the number of their heads is equivalent to calculating the number."
"Great. Next we have to look at the number of heads, is it related to anything else?"
The classmates bowed their heads and picked up the chicken's legs. The rabbit's legs were picked up two.
It can be clearly seen that the chicken has only one head and one leg left, and the number of heads and the number of legs are exactly the same.
Lu Zhihao looked at everyone's movements with a blank look.
"How many legs are left in this cage?"
"34/2=17, there are 17 legs left." Ambebe answered.
"now what?"
"After halving, the number of chicken heads is now equal to the number of legs. The total number of legs is 17 minus the total number of heads. 12, for chickens, it has all been lost. 17-12=5 already contains no chicken.

"Oh, what about rabbits?"
"For the rest of the rabbit, the legs are 2, the head is only one, and the legs are twice the size of the head." Ambebe said, picking up the remaining two legs of the rabbit, "but just now." At 17-12, each rabbit was followed by a leg, and the remaining number of legs was the total number of rabbits, so there were five rabbits left."
Ambebe said it in one breath, he would count before, but certainly can't say so clearly.
Lu Zhihao immediately understood, although he has now solved this problem with a binary equation, and has not heard of this clever calculation method, but with the addition of intuitive paper, the problem-solving process has become very clear.
So smart and great!
Touching the chicken and rabbit on the ground, he only has this feeling.
Master Lao Lin changed another animal. This time, there are 3 feet and 2 eyes and 6 eyes and legs of the turtle. The problem is more difficult than before.
Some people are still drawing pictures, but some people are mentally calculating, and Master Lin has not stopped.
There are no rules here. There is no need to use any formula or method. Everyone can have their own ideas.
Everyone is very happy and he is very happy.
If you can continue to learn this way, it will be fine!
When I finally left the dormitory, I looked at the stars, and he only had this idea.

The rising sun is rising.
Monday, Oasis Base, meeting room.
Uncertainly yawned into the conference room and shook the freshly brewed instant coffee. He got up at 7 in the morning and had 8 o'clock for a casual breakfast.
The 8 o'clock regular meeting will open until 8:20, 10 minutes left for them to pack things, 8:30 to go to the children to class, the child is hard, in fact, the teacher is not easy to be right.
oss entered the conference room on time at 8:00 in the morning, and they simply nodded and quickly entered the conference process.

The teachers in each group will first summarize the teaching situation in the next week, starting from the high school group.

The responsible teacher of the Jinbei High School group taught for twenty years, and he has more experience than him. He directly reported several average results, indicating that under the elimination of the competition system, the students' performance has improved significantly.
Explain, the names are the special traits that were mentioned in the first meeting, and may be able to rush the provincial team's good seedlings. This sample proves that the student's performance has improved significantly and is not representative.
The junior high school group also painted the gourd, and listened to the sleepy, unscrewed the plastic cup, drank the coffee, and then was named.
"What about the teacher's small high group?"
"Do you have to do it?"
The office suddenly calmed down, and everyone talked about it because of his words, suddenly silent.
"I have said before, I hope that teachers can use more accurate data to describe the children's situation, rather than choose very vague words, especially - make do."
I laughed and laughed, not very concerned.
At this time someone looked at him and shook his head.
That was the high school teacher Feng Lao teacher who reminded him of the boss's difficulty before.
Solve: "It's not bad, our test papers are not fixed, so the results really don't see anything."
Vice-President Zhang was silent for a while, and finally said: "Talk about the children you think will be the last to participate. How are they?"
"Yuzhi, Lin Chaoxi, Zhang Liang, Wang Feng, Lu Ming are very smart, the results are very stable, but they have a bad relationship with each other, it is difficult to team up to participate in the competition."
"Children, what is the relationship," said one teacher.
"To participate in the competition together, it is not to ask the team to cooperate, the average score." Another teacher said.
The solution did not speak, who said that he smiled and nodded.
"The results are stable." Vice President Zhang summed up and ordered Xiaozhong Group.
Everyone has finished the round and it is almost there.
"Finally, I have to work hard for the teachers, and once again reaffirm the discipline with the students."
Vice-President Zhang looked at the book and said: "On Sunday night, the high school team found that the two students did not return home at night. They have been fired. The base is very big, and it is very unsafe to stay at night. You should emphasize it with the students.

Hearing the words, the solution continued to smile and did not say anything.
After the meeting, he held a plastic cup and yawned, ready to go downstairs.
Teacher Feng of the Xiaogao group pulled him: "How do you top the principal?"
The answer was helplessly laughed: "I am too embarrassed, Teacher Feng."
"Your voice is okay, it is obvious that there are emotional problems, don't forget, your internship report, but he wants to sign." Feng said.
"I understand, thank you."
"I know that you have an opinion on Vice President Zhang, and bear it." Feng patted him on the shoulder and quickly left.
Explain, he can have any opinions, he is just a college student who needs a chapter in the internship report.
Previously, due to chance, the Anning Jin Cup training camp recruited people at their school. He tried to invest in an internship resume and applied for it.
At that time, he was not the vice president of Zhang. It is said that the leaders of the Municipal Education Bureau paid special attention to the Jin Cup this year and said that they must make achievements. Therefore, a well-known teacher from a large mathematics province was airdropped and was the vice president of Zhang.
In fact, I understand that I am very contradictory to Vice President Zhang. On the one hand, I feel that he is too Sparta, but some educational concepts are quite reasonable.
He studies mathematics and has no experience in education. He can only say what he does.
However, getting along with the children for so long, saying that no feelings are also fake.
In fact, before Vice President Zhang asked the question, he really wanted to say that there were several children in the class who seemed to have improved their grades. However, the leaders did not care about this, and he shut up.

"Do you want to listen to the results first, or do you have classes first?"
In the small high-class classroom, when I went to the front of the podium, I began to tease the students.
Lin Chaoxi yawned and said to the class: "First~上~课~"
Solve the laugh: "Then I will report the results first."
Sure enough, this is the routine, it is not unexpected.
Explain: "Friday's exam is the relatively simplest one in these days, mainly to let you have a good mood to go home to play, so this score should not be too serious."
"Teacher, you hit us!" The students complained.
"Well, change it. There are a few students who have made me very surprised and have made great progress. I feel that the battle of the mid-term exam will be difficult to solve." Xiaoran laughed. "Below, I will emphasize it..."
Unlock the paper and start to read the name.
"Chen Chengcheng, An Beibei, Luo Xiaojuan, Yao Xiaotian, Hanamaki..."
The children whose names were reported were very happy, and they looked at each other incredibly.
While hearing Chen Chengcheng's performance leaps and bounds, Zhang Liang's face is stinky.
Lin Chaoxi had no time to be dark from Zhang Liang’s face. The more she listened, the more she was shocked. Apart from Luo Xiaojuan, they were all children of this wave.
Does Lao Lin bring his own mathematics, and it will be good if he scores?
"Lin Zhaoxi, what are you looking at?" The solution stopped and looked at her. "You already know that you are tied for the first time with you?"
"No, no." Lin slammed his head and suddenly stopped, "What?"
"I will praise you again?"
"No teacher!"
"Let's take the papers of your group." Explain.
She went up and asked the second set of papers to her, and asked casually.
"What did you do last night, so sleepy?"
Lin Chao suddenly stunned and looked at the solution without understanding. Did he know?
"Have a good rest at night." 2k novel reading network
