That day, Wang Daben walked into the elementary school with another person. The man was a big man, a crisp suit, and he was carrying a suitcase, as if he was going out to get on a plane. Wang Daben introduced this person to Principal Zhao Sihua as follows:

"This is our company's scientific advisor, Mr. Lang. ”

"Hello, Headmaster. ”

This Mr. Lang has a good baritone voice, and his voice is rich and magnetic, which he introduced to the children in science lessons by Wang Daben. The personable Mr. Lang is easy to impress, and Principal Zhao Sihua warmly welcomed him.

After school that day, another child ran to the park to play. It seems that the classroom of the extracurricular class is being renovated and has to be closed for a few days, so the children have free time to come and play. Ah Kang saw Zhang trotting from a distance, with Hua Man and Xia Ye chasing after him. Zhang trotted and couldn't run, leaning against a tree and panting. The two girls caught up and shouted at him. Akon likes to pay attention to the quarrels between children, and finds it funny when they are anxious and angry. So it flew over and stood in the trees and watched the excitement.

When Huaman saw that Akang was on it, he said to it in a loud voice:

"Ah Kang, Zhang trotted to steal Mr. Lang's 'molecule'. ”

"What? Mr. Lang's?"

"Molecule!"

"I didn't steal!" Zhang retorted.

"You still don't admit it? ”

Zhang trotted out the pocket on the side of his jacket for everyone to see, it was empty.

"On the other side. ”

Zhang Xiaotrot hesitated, refused to turn the other side again, and then changed his words:

"I'm just borrowing it for a few days and I'll definitely give it back to Mr. Lang in the next class. ”

Xia Ye said: "Borrow, but you didn't ask Mr. Lang, you hid without saying a word." ”

Akon understood something, but he didn't understand the point, and he shouted:

"Stop, don't argue yet, can you show me what the hell you mean by 'molecule'?"

Zhang trotted reluctantly out of his pocket the "molecule". A red ball and two smaller blue balls, linked together by a wooden pole. Ah Kang knew that this was a teaching aid for molecular models used in chemistry class.

"This is it. Hua Man said and snatched it, "You say, did you steal?"

"I didn't steal it, I'll pay him back. Zhang Xiaotrot said angrily, and then ran away.

Looking at the red and blue balls, Ah Kang said, "Interesting, next time I will also listen to your science class and get to know this Mr. Lang." ”

When Mr. Lang came to science class for the second time, Akang stood early on a branch outside the classroom window. Mr. Lang walked into the classroom, opened his suitcase, took out the chemistry class models from it, and handed them out to each student one by one. After sending the model, he stood on the podium and cleared his throat, held up a red and blue spherical water molecule model, and told the children in a deep baritone:

"It's the 'molecule'. ”

Then there was another black ball.

"It's 'atoms'. ”

Then a white ball is attached to the black ball.

"It's 'electronic'. ”

He walked back and forth twice on the podium, as if he was thinking about something.

"It's your turn, tell me what you're holding in your hands?"

None of the children raised their hands, and they didn't even figure it out.

Mr. Lang walked around the classroom and finally looked at Tarzan, probably because Tarzan was the tallest in the class.

"This classmate, please answer my question. ”

Tarzan stood there timidly, and replied unconfidently:

"It's the 'molecule'. ”

Mr. Lang shook his head.

"No, this method of vocalization is incorrect. First of all, you have to keep your chest up and your head up. The first step is to 'sink the dantian', 'dantian', do you know? Vocalization starts from the stomach, then to the chest, then to the mouth, and finally forms a head cavity resonance. Come, please imitate me, this is the 'molecule'. ”

"It's the 'molecule'. ”

"There is progress, please sit down, and practice more. Students, do you like singing?"

Several girls replied, "Yes!"

"Shall I teach you how to sing? Let me think about which one you are suitable to sing. Do you know the 'sound of music'? is that 'Doremi'?"

"No, it won't. ”

"I'm here to teach you, this song is very helpful for beginners to master scales. ”

The second half of this science lesson is for Mr. Lang to teach the children to sing "Doremi". Mr. Long is very good at singing. At first he taught the children to sing in Chinese lyrics, and then he wanted to teach the children to sing in the original English, but then the bell rang at the end of class.

At the end of the children's happy science lesson, Akon happily listened to the children's singing outside the window, and he liked to listen to the "natural sounds" of the children. But it's a strange science lesson, and this Mr. Lang is weird.

Ah Kang stood on a branch and watched Mr. Lang walk out of the primary school gate, walk towards the intersection, and stop at the bus stop on the side of the road. After a while, a No. 2 bus came, and Mr. Lang got on the bus. The bus drove away, and Akon took off, tracking the car in the air. When the car arrived at the station, Akang also found a place to stop. The bus drove away, and Akon continued to fly.

At every stop, people get off the bus and get on the bus. Akon carefully watched everyone who got out of the car. At the fourth stop, Akon saw Mr. Lang get off the bus, and he dragged his trolley suitcase along the sidewalk for 200 meters before turning into the gate of a flat. Ah Kang hurriedly flew over and saw a plaque hanging on the side of the gate, which read: New Oriental Song and Dance Troupe. There was a building in the courtyard, and Mr. Lang walked in, and the sound of musical instruments playing could be heard from time to time in the building.

Ah Kang flew around the building several times, and finally spotted Mr. Lang's shadow. There were many people in a big house, and there was a conductor who was organizing everyone to rehearse the chorus, and they were singing: "A big river, ......". Mr. Lang was in the middle of that crowd.

Mr. Lang's identity has been answered, he is a choir actor. Why would he pretend to be a science advisor to scam the kids?

If Mr. Lang were to be blamed in this way, he might feel wronged. The cause has to start with Wang Daben.

One day, Mr. Lang was conducting a rehearsal for the elderly choir in the square, and Wang Daben happened to pass by. He was attracted by Mr. Lang's magnetic voice and stopped to watch. Seeing this dignified person, very personable. He thought to himself, this is a talent, maybe he can use it for me. At that time, he was looking for an instructor for his "Paranormal Child Development Program".

Wang Daben stood aside, as if enjoying the singing of the elderly choir. When Mr. Lang was about to leave after the rehearsal, he walked over, handed his business card, and then cordially invited Mr. Lang to a nearby tea room for a cup of tea. Mr. Lang is a warm-hearted person, often coming to help the senior choir, and also helping some units to rehearse theatrical programs. Nowadays, many companies often engage in self-entertaining performances at the year-end summary meeting, and Mr. Lang thinks that Wang Daben must also want to ask him to help with such a favor. The two drank tea, and Wang Daben talked about his "abnormal child training plan".

Mr. Lang was quick to express his embarrassment, because he was really not very good at understanding scientific things. Wang Daben inspired Mr. Lang in this way:

"Science, children will understand sooner or later, there is no need to rush about this. If I tell them it now, they still find it difficult to understand and accept. We need your expertise, and children love singing more than 'science'. You can teach your child to sing while teaching them some scientific concepts. ”

Mr. Lang was skeptical of Wang Daben's plan, and it was not until Wang Daben promised him a very generous reward that he made up his mind to cooperate with Wang Daben.

Now that the crow has deduced what happened, it is thinking about what to do next, how to expose Wang Daben's deception, how to get that "elegant" liar out of the science class?

After school the next day, Akon invited a few children to the park under a tree to discuss a plan with them. Ah Kang asked the child first:

"Do you know what 'science' is?"

"Of course we do. Natsuha said, "Science is what Newton and Einstein studied all day long. ”

Hua Man Says:

"And Tu Youyou, she is our country, she won the 'Nobel Prize in Science'. The medicine she developed saved many lives. ”

Akang Says:

"Every week Mr. Lang comes to teach you science, can you tell me about what kind of 'science' he teaches?"

"Akang, are you joking? Mr. Lang will only lead us in singing. Zhang trotted and hurriedly said. Hua Man said: "I like to follow Mr. Lang, he is very good at singing. ”

Natsuba also agrees with Hanaman's words. Tarzan said: "I prefer to sing with Mr. Lang, it is much more interesting than 'science'. ”

The children's answers surprised Akon. It's important that children love to sing, says Akon:

"You like to sing along with Mr. Lang, I like to listen to you sing. Why don't you sing it now and let me hear it?"

So the children sang "Doremi" together under the tree, and Akon listened silently, his mind having abandoned his original plan.

There is a full-time music teacher in the primary school, and her surname is Yan. The children in the school were afraid of her because she was strict, and even some of the younger teachers were afraid of her.

Principal Zhao Sihua was quite helpless about Teacher Yan, and the Teacher Yan he knew was not like this before. In the past, Teacher Yan was famous in school for being "gentle and beautiful". But in recent years, there have been some changes in her body, yellow spots appear on her fair face, she often feels upset, and a lot of her hair falls out. To make matters worse, there is severe insomnia.

In music class, Ms. Yan requires students to do absolutely what she asks. Sit upright, raise your head and chest, and don't make unnecessary movements. But there are always students who can't do this, which makes her lose her temper in almost every class. The child who is most afraid of taking music lessons is Zhang Xiaotro. Zhang Xiaotrot is a child with mild ADHD, and it is difficult for him to sit in a chair for ten seconds without moving. In every music class, I can always hear Mr. Yan's roar:

"Zhang Xiaotrot, go to the back of the classroom and stand!"

Teacher Yan often teaches or admonishes his students in this way:

"You are like a small tree now, and you will become the pillars of the country in the future. Trees must grow straight to be pillars, and crooked trees can only be burned as firewood. There are always some shortcomings and faults in children, and teachers should help you overcome them. Just like a small tree loves to give birth to some branches and forks, the gardener must break them in time, otherwise the tree will not be straight. When the teacher criticizes you, you will be unhappy, and it will hurt if the branches and forks of the tree are broken. ”

These words gave rise to an indescribable fear in the hearts of some children. Tarzan had several nightmares in which his fingers or arms were snapped off by his life.

The annual campus choir festival is coming, and the song chosen by Taishan and their class is "Little Pine Tree". In music class, Ms. Yan instructed the children to rehearse. Needless to say, Zhang Xiaotrot was punished again. Zhang Xiaotrot, who was standing at the back of the classroom, felt relaxed, just snorted a few times, and the teacher's stern gaze didn't need to stare at him anymore.

Teacher Yan was angry again, this time it was Taishan's turn.

"Tarzan, you're like a 'little fool'. Why do you always be half a beat slower than everyone else? Go to the back and stand behind!"

Tarzan felt innocent, and he was worried that he would be scolded for singing wrongly, so he sang very carefully, but he was still punished. He stood beside Zhang Xiaotrot and deliberately pretended not to see Zhang Xiaotro's eyebrows.

The third to be punished was a fruit tree. The voice of the fruit tree was sharp and high, and Teacher Yan believed that the fruit tree was deliberately making strange noises, disrupting the order of the classroom and sensationalizing the public.

Fearing that she would be the next to be punished, the timid children in the class were so scared that one girl even cried. The children were depressed, and "Little Pine Tree" sounded more like a "little dead tree", so angry that Teacher Yan slapped the table. Fortunately, at this time, the bell rang for the end of class, and Teacher Yan walked out of the classroom with a snort, and the children breathed a sigh of relief.

Every time after a music lesson, Mr. Tian Ding saw that the children in his class were depressed, and he felt very uncomfortable. She learned about the situation in music class and wanted to talk to Teacher Yan, but she didn't dare. Teacher Yan is much older than herself, and she has just done one or two jobs as a teacher, so she seems to be not qualified to express her opinion on a senior.

Principal Zhao Sihua received calls from several parents complaining that Teacher Yan was too strict with his children. Principal Zhao Sihua had no choice but to invite Mr. Yan to his principal's office to talk. Zhao Sihua relayed to her the protest from the parents, but Teacher Yan immediately became angry, accusing the principal and the school of not paying attention to music education at all, and deliberately directing students' energy to math, Chinese, and English classes, causing students not to take music lessons seriously.

The conversation broke up.

In the park after school, Akon discusses their troubles with a few children. Zhang Xiaotrot said:

"I want the school to cancel music lessons. ”

Flower full against.

"I don't agree, I love singing in music lessons. Although the teacher is a bit harsh, several of you are also at fault. ”

The Fruit Tree Says:

"I wish there was a different music teacher in my class, or I would have to ask my mom to transfer me. ”

Tarzan Says:

"I hope that the next time I have a music lesson, I'll be sick at home and won't come to school. ”

Zhang Xiaotrot said:

"I hope that the next time I have a music lesson, Mr. Yan is sick at home. ”

As soon as these words came out, the children were silent, and they all looked up at the crow Akang in the tree.

Ah Kang shook his head helplessly and said:

"Teacher Yan is already a patient. ”

Teacher Yan is indeed sick. She went to the hospital, where doctors announced that her blood pressure had reached a very dangerous level and that she had to be hospitalized immediately and treated in bed.

Teacher Yan is sick and hospitalized, what about the children's "choir festival" in the primary school?

Don't be afraid, and Mr. Lang. Mr. Lang was willing to guide the children's rehearsals. Taishan's class participated in the performance of the "Campus Choir Festival" as scheduled, but did not sing "Little Pine Tree" as originally planned. The track was changed to the interlude "Doremi" in the movie "The Sound of Music", and Hua Man served as the soloist in it. Their performances were very successful and they won awards.
