28. Teachers teach earnestly, cultivate wisdom, bloom flowers, and dispel ignorance

When I was studying on Monday morning, Dongfang Hong wanted to write an application for joining the league, but when he first mentioned the pen, he didn't know the nature of the youth league organization, and he had to find a league constitution to study to understand. asked Yu Chunhua, who was at the same table, who could have it, Yu Chunhua took the pen and touched her face, looked up and thought about it, you have to find Secretary Ai of the Youth League Committee of the school, he must have. Dongfanghong pondered, this early in the morning, Secretary Ai had to come to school from home after breakfast, so he settled down to study. Soon the bell rang and went to breakfast, at the door of the restaurant, from a distance to see Ximen Guanghui coming, Dongfang Hong thought to himself, Ximen is going to join the group, he must have it, why not ask him to borrow a copy?! He shouted to Ximen to stand for a while, but Ximen didn't hear it and walked into the restaurant quickly. Only then did I think of what Simon said last time that I should see each other as little as possible, and the boss in my heart was unhappy, and scolded, stinky and scolding, I really see that you are about to join the group, and the eldest uncle saw his brother and daughter-in-law - hidden! This time, I'm not looking for you, let's see if my application for joining the group can be written?! He ate and walked out of the dining-room after eating, and saw Simon again, but Simon swished past him. Dongfanghong didn't pay attention to it anymore, and said secretly, don't think that without you, you can't be a slot lamb! Don't look at my earlier answer to you, I thought you were okay at that time, so I gave you a good look; Now I don't see you much, you go far away, I have a red face, I don't believe you try, if you meet again, you will talk to me in a hurry, I won't talk to you, see who can beat whom?! At this time, the class leader Cao Zhen came up from behind, and the two returned to the classroom area.

As soon as I entered the school gate, I saw that there were many students surrounded in front of the bulletin board, and when I stepped forward, it turned out that it was the "Decision on Learning from Ximen Guanghui" of the school Youth League Committee and the student union, and the two came forward to watch. Dongfang Hong said secretly while watching, sue you Ximen Guanghui! Don't look at me Dongfanghong wants to learn from you, learning is learning, things are things, ordinary people talk, smoke big cigarettes, and take a lot of smoke, we are each a yard! Keep watching. At this time, someone in the back shouted both Cao Zhen and Dongfang Hong, and when he looked back, it was Yu Chunhua. asked what was the matter, Yu Chunhua said, Teacher Liu asked me to find the two of you and go back to the meeting immediately. The three of them ran back to the classroom, where Teacher Liu was waiting. It turned out that according to the decision of the party branch, the teaching office should make a big noise in the learning activities, and temporarily arrange a day for the whole school to attend classes, and all classes should act quickly. Teacher Liu saw Cao Zhen burning the fire and said, "Today's class is carrying out activities, we are the rescued class, we must bear the brunt of it, and we can go out first, what do you think you can do?" You have to hurry, you have to fall behind the rest of the class. Cao Zhen said, this is easy to do, I just saw that the door of the restaurant is very dirty, let's go there to clean up the garbage! Labor Commissioner Bafu said, no, what if you don't have a shovel to pick up the garbage, and now you go out to borrow it and don't rush. Dongfanghong said, there is! Let's go to the society to clean the glass, we don't need any tools, just a handkerchief. Teacher Liu happily said that it is feasible to wipe the glass, but where to go? Dongfanghong said, just go to the town government, last night I went to the street and saw that the windows of their offices can be buried, all of them are the kind of eyebrows and eyebrows, it's good to go there. Teacher Liu said, it's still good to use the Oriental Red Brain Melon, let's act immediately! Cao Zhen shouted, and all the students immediately gathered in front of the classroom!

Suddenly, the team set off. I saw the red flag of "Liaoyang County No. 3 Junior High School Class 3" fluttering in the forefront, and the students sang the song "Socialism is Good" loudly:

Socialism is good,

Socialism is good,

The socialist people have a high living status!

The reactionaries were defeated,

Imperialism fled with its tail between its legs.

The great unity of the people of the whole country,

It has set off an upsurge in socialist construction! Construction climax!

The singing was loud, and the procession marched through the street with neat steps. On the south side of the road, there are three large slogans "Long live the three red flags", and a slogan on the north wall of the road is even more eye-catching, clearly painted with ten bright red characters that are more than one person tall -- "Never forget the class struggle", and the summer style "Chairman Mao" is also written in wild cursive script. The students looked forward and backward, left and right, and after a while, they arrived in front of the town government.

Cao Zhen asked Teacher Liu, did you still talk to the town leaders? Teacher Liu said that there is no need to find a leader, just say hello to the communication room. Cao Zhen did so, and after saying goodbye to the doorkeeper, more than 50 students rushed up, only to see that the windows of the various offices facing the street, the long small corridors in the house, the canteen in the backyard and other places were full of students standing in front of the windowsills. Then, the doorkeeper of the communication room brought a few basins of water to distribute them everywhere, and said to Mr. Liu, the leaders of the town and all the cadres have gone down to the village to leap in, and your school can come to help us clean the glass, and I would like to express my gratitude on behalf of the leaders of the town! I won't say anything, this teacher no matter what, you have to tell me your name, and how many classes you have been in for a few years, and when the leader comes back, I can have an explanation. Teacher Liu said, we come to be good people and do good deeds without leaving a name, I can only tell you that we are in the sixth class of the third middle school a year. The janitor said thank you again and left.

There was only one person at the window where Dongfanghong was, so Mr. Liu came to the front and took out a handkerchief to help wipe it. Dongfanghong said, Mr. Liu, you rest, let me wipe it alone. Teacher Liu said, the teacher, like you, is learning from Ximen, and you can't have two empty paws and one hand without stretching out. As soon as Dongfanghong heard that the "empty two paws" was strange and interesting, he felt that Mr. Liu was very kind, so he wiped it with a smile.

Rubbing and rubbing, Teacher Liu whispered to Dongfanghong in his ear: "Have you had your menstruation?" ”

"Lisuo, not at all last night."

Teacher Liu nodded knowingly, and sang a little song while wiping, gentle and delicate. Dongfang Hong listened carefully, but he still didn't know what to sing, he had the heart to ask, but he was embarrassed to speak for a while. Teacher Liu continued to hum and rub.

Dongfanghong listened while wiping, and when Teacher Liu's song was over, he whispered: "Teacher Liu, you just mentioned learning from Ximen Guanghui, I have something I want to ask the teacher, okay?" ”

Teacher Liu showed a very good-looking smile and said, "What's wrong with that, you can say it!" ”

So, Dongfang Hong told the last conversation between Ximen and Dongfang in the student union room, from the end. Finally, he said, "I have been summing up, and if I want to say that Simon is not right, it seems to make some sense; If you want to say that what he said is right, I really can't accept it from the bottom of my heart, so I ask Mr. Liu to help me analyze and analyze. ”

Teacher Liu said gently, "I understand! But the teacher has to tell you first, you have something in your heart to talk to the teacher, and you are right. The reason is that what you just said belongs to the private words of our women, a woman, no matter whether she is big or small, will always detour from time to time similar to the things you just said, and her heart is very entangled, people are the same heart, and the heart is the same, just like the teacher used to be in the third grade of junior high school for a while, and she also detoured similar things, and she couldn't think about it, and if she couldn't think about it, it would affect her learning feelings. So, it's good that you have something in your heart to be able to say to your teacher. ”

"Teacher, have you ever been there?"

"Yes, I have been to a detour, when I was about to graduate from junior high school in three years, I was always summing up and thinking all day, and even delayed my studies, and I barely reached the admission line in the entrance examination, and I was forced to enter high school; And the boy was admitted to a technical secondary school, and the two were pulled down. ”

"Does the teacher still want him now?"

"Sometimes I think about it, and I forget it. But at that time, I was with him, just like you and Ximen now......" Teacher Liu whispered to Dongfang Hong's ear, "At that time, it couldn't be said that it was love......"

"What's that?"

"To put it more seriously, it is the budding of the heart, in other words, it is the beginning of love, sometimes you don't dare to think about it, you don't dare to think about it, you must know that at this time, it is still very far away from the love that ordinary people say, or you don't know what love is; To be precise, it's just that the two are better, it's still a kind of interaction between the opposite sex, from the nature of it, it's just a friendship, friendship and love are absolutely different, the relationship between the two is close at hand, and each other is very far away, do you understand? ”

"Does the teacher mean that there is love in friendship, and there is friendship in love?"

"That's not it! The relationship between the two cannot be said to be that you have me and I have you, so it confuses love and friendship, here objectively, there is a clear boundary: if two people are dating, you want to be with him immediately, or not immediately, want to live with him in the future or in the future, once you have this clear idea, I say it is a clear idea, and it is consistent with each other, then I am afraid it is love. Here I emphasize that it is mutual, mutual is love, not mutual, it is called unrequited love; On the contrary, if you don't want to live together, and you think that there is no such possibility at all, and you are even vigilant, and this vigilance is still very conscious, then it is not love, at most it is friendship, and even friendship cannot be reached. Which one do you see? ”

Dongfang Hong thought about the fragment and said very seriously: "We belong to each other just a little bit of good, at most it is friendship, because my contact with him is only occasional, and it is all a detour, I have never thought about the morning and twilight, the kind that rolls into a group and trains into a block, and I don't have the idea of living together in my heart, from my side, I am just willing to meet occasionally!" ”

If so, it is still a friendship and association between people of the opposite sex, and you must know that this kind of interaction is allowed in the school. So the teacher thinks that in order to join the group as soon as possible, Ximen Guanghui proposed and asked you not to meet him, and even inadvertently met and couldn't speak, obviously he was wrong, strictly speaking, he was an unreasonable request, in a sense, it also showed that he was a little narrow-minded, and even said that his motivation for joining the group was a little impure, and a young man should be open-minded! ”

"And what about learning from Simon?"

"Learning is learning, this can't be confused with what we said, learning from him is to keep up with the advanced, you have to learn from him, because he saved you, of course, you have to overcome the simple idea of gratitude, don't think that he saved you, you just learned from him, he hasn't saved the teacher, didn't the teacher come out here to clean the glass?!"

Dongfang Hong nodded, and asked again: "Teacher Liu, you just said that the school allows friendship and interaction between male and female students, what does this mean?" ”

Teacher Liu said: "To put it bluntly, it is not allowed to fall in love, let alone have a partner; Because middle school students are still young, once they are all like that, what kind of school is it called? ”

"Teacher Liu, I understand!"

Teacher Liu said: "The key is to grasp the difference between friendship and love, and to be vigilant, as Vladimir Ilyich Lenin said, it is a fallacy to take a step forward in truth!" Of course, the teacher is borrowing the phrase leader here, in order to be able to talk about the problem more thoroughly, strictly speaking, it is not very accurate, do you understand what the teacher means? ”

Dongfanghong nodded and said, "Teacher Liu, I understand!" ”

After the glass was wiped, it was soon noon, and everyone returned to school to have lunch, and in the afternoon, they were active in the school. In the evening, Cao Zhen asked Dongfanghong and Yu Chunhua to write a report respectively, and sent it to the school Youth League Committee and the student union in time, and went to the school bulletin board the next day. Mr. Liu was very satisfied.

Life as a middle school student is always stressful! From Tuesday, classes will start as normal again. According to the requirements of the Provincial Department of Education, in order to reflect that education should be in line with production and labor, there must be a plant course in the first grade of secondary school, with two classes per week. Class 16 is scheduled to be taught by Mr. Zhao Dongcheng in the first period on Tuesday morning and the third period on Friday afternoon. Mr. Zhao was about 50 years old, graduated from Tianjin University before the liberation, and taught in the provincial capital Shenyang for a long time. It is said that Mr. Zhao is very serious in teaching, very strict with students, and has a loud voice. After breakfast, the students gathered in the classroom, only to see Mr. Zhao walking into the classroom with the lesson plan in his eyes. After Mr. Zhao gave the salute, he began to teach.

Teacher Zhao said: Students, today I will give you a plant class, first let us learn the first lesson - the flower of plants: flowers are the reproductive organs of angiosperms......

Dongfanghong, who listened with his ears up, suddenly felt that he had spoken well! Flowers are just beautiful in the eyes of ordinary people, but when Mr. Zhao talked about it, it was actually a reproductive organ. I thought it was good to take a botanical class, and the knowledge I learned was both new and interesting.

Zhao Qiang at the front table grinned, and Mr. Zhao forced his eyes to look, so he asked Zhao Qiang to stand up, and Mr. Zhao said, "Don't you laugh!" Let me ask you, what do you mean by reproductive organs? ”

Zhao Qiang replied: "The reproductive organs are able to raise children!" ”

The students burst into laughter, and Teacher Zhao said, "Everyone should be quiet! ”

Suddenly it was quiet again.

Teacher Zhao said: "Zhao Qiang's answer is wrong! We studied botany, and the reproductive function of plant flowers is to produce fruits, including seeds. The reason for the mistake is that he confuses the distinction between species; Then there is Zhao Qiang, he speaks vulgarly, as a middle school student, you can't say raising children, let's speak civilly, to be elegant, you say this, and the sentence "raising children is not called raising children, calling people", the teacher sees no difference, this is not good! ”

Another burst of laughter.

Mr. Zhao continued: "In the real world, there are many types of flowers, which can be said to be strange, and their structures are also very different, and the structure of typical flowers is generally composed of receptacles, calyxes, corollas, stamens and pistils. Flowers with the above parts are called complete flowers, such as peach blossoms; Missing any part of it is called an incomplete flower, such as a mulberry flower. It is important for students to pay attention to the teacher's remarks, in which the stamens and pistils are the specific reproductive organs of the plant; What is even more interesting, or incomprehensible, is that the stamens and pistils grow within the same flower, which is called a hermaphroditic flower, such as a tomato; and the only one, is a unisexual flower, such as corn; The flowers of both sexes are also called hermaphroditic or monoecious, of course, there are different bodies with different beads, which are divided into male trees and female trees, such as ginkgo biloba, which belongs to dioecious or dioecious......

Teacher Zhao talked about this, looked down, and found that Dongfang Hong's mouth was grinning, so he shouted to stand up, Dongfang stood up, Teacher Zhao asked, what are you laughing at?

Dongfanghong replied: "I didn't laugh, I just grinned......"

Teacher Zhao said: "The teacher also wants to ask you, what are you grinning about?" ”

Dongfanghong said: "I think dioecious plants are not as good as monoecious, the reason is that monoecious plants have their own superior conditions, just like a man and a woman have been combined together from the origin, neither divorce nor contradictions, virtually reducing a lot of trouble; I say this as an analogy, not to deliberately blur the boundaries between species, but to fully express myself and be easily understood by those who hear me; The dioecious plant is relatively inferior to the monoecious, the former has a problem of selection after the fact, just like people, will produce a lot of troubles, the result can bear fruit, so that whether it can live a long life, whether it will grow old, this is difficult to say. So I think ......"

"Report!" Zhao Qiang asked to speak.

Teacher Zhao said: "It's you Zhao Qiang again!" You reported too early, you should let Dongfanghong fully finish, can't you raise your hand again? ”

Dongfanghong said, I'm done.

Zhao Qiang stood up and said: "I don't agree with Dongfang's speech, assuming that according to what she said, she thinks that it is better to be monoecious, then it is bound to be an individual, both male and female, both male and female, and the result is that men are not male and female, wouldn't they become two sons!" So, I think it's better to be dioecious. ”

Wow there was another burst of laughter.

Teacher Zhao said: "The two students should not listen to the conversation as a general joke, the teacher thinks that they can use their brains, can put forward questions and opinions, and the problems involved are very deep, and the teacher encourages this kind of learning attitude." I'm going to move on to what I didn't finish in this lesson. ”

Therefore, Mr. Zhao talked about the specific composition of flowers, and talked about the concepts and functions of stamens, pistils, ovary, stigma, pollen, anthers, petals, filaments, perianths, and receptacles.

After all the content was finished, Mr. Zhao looked at his watch, there were still 19 minutes before the end of class, and said that because there was a lot of content in this class, in order to be able to digest and deepen the memory, the teacher wanted to use the remaining time to ask some questions. The first question is the composition of the stamens. Please raise your hand. Suddenly, more than a dozen students raised their hands. The teacher assigned Bafu to answer.

Bafu stood up and said, "The stamens are composed of three parts: the ovary, the columella, and the stigma. That's it. ”

A few students immediately laughed, and Teacher Zhao also smiled and said, "Ba Fu, you can think about it again, you can answer again." ”

Bafu said confidently: "Don't think about it, because this question is relatively simple, and I must have answered it correctly." Then he sat down.

Teacher Zhao asked, "Everyone said, is Bafu's answer correct?"

About a dozen students below said in unison: No! All hands up.

The teacher assigned Yu Chunhua to answer.

Yu Chunhua said: "The stamens are composed of two parts: filaments and anthers; And the ovary of the bastard, the columella and the stigma that Bafu replied to were the three components of the pistil, and he answered completely in reverse.

When Ba Fu heard this, he immediately raised his hand and stood up again, but he didn't get the teacher's permission, and replied directly unconvinced: "It's not that I'm wrong, but you're Yu Chunhua!" It's a common-sense question! Even first-graders know that only male stamens have a columella and stigma! What is a flower pillar, what can be called a column, what is a stigma, what can be called a stigma, it must be a man, no! I was in a hurry to say that I was wrong, it must be a male stamen! This doesn't need to be elaborated at all, let alone explained, Mrs. is a clear matter! ”

Immediately, the students all laughed, some laughed out of tears, some laughed forward and backwards, and so on.

Teacher Zhao on the podium seemed to be angry and said, "Yu Chunhua's answer is correct, and Ba Fu's answer is completely wrong. It is enough to prove that you did not pay attention to the lectures at all, and you will have to pay attention in the future! The second question that follows is, what is the function of filaments and anthers? ”

After speaking, Teacher Zhao looked at him and asked the class leader Cao Zhen to answer.

Cao Zhen stood up and said: "The filigree of the stamens is generally long and slender, and there is a vascular bundle in the center, whose function is mainly to hold up the sac-like anthers at its tip; The anther is composed of two chambers, each chamber has two pollen sacs, and when the pollen matures, the pollen sacs rupture, and the pollen comes out like sperm and binds with the pistil. I'm done. ”

Teacher Zhao nodded and said, "The answer is completely correct!" Finally, a slightly more complicated question, how are the fruits of plants formed? Please think about it and see who can answer? ”

Dongfanghong was the only one in the classroom who raised his hand, and Teacher Zhao said, then you should answer! Dongfanghong stood up and said: "The fruit of the plant is due to the pollen of the stamens ripe, which is attached to the stigma of the pistil at the right time, and then the pollen enters the ovary at the bottom through the flower column under the stigma and meets the ovule that grows in the ovary, which is called fertilization, and then the ovule develops into a seed, and the ovary wall develops into a derma and forms a fruit together with the seed." ”

Teacher Zhao smiled and said, "Dongfanghong's answer is very good! The teacher will ask you a small but crucial question, why can the pollen of the stamens adhere to the stigma of the pistil? ”

Dongfanghong couldn't answer for a while, stood and pondered, Teacher Zhao said, think about it, don't worry. Dongfanghong suddenly said: "I remember, because the stigma of the pistil is a globular or disc-shaped object, with a protruding garden-like object on it, and this object can secrete mucus, which is very important, it is very suitable for the fixation and germination of stamen's pollen." ”

Teacher Zhao said: "Dongfanghong's answer is completely correct! “

At this time, the bell rang for the end of class.

The students walked out of the classroom one after another, and one of the students stepped forward to look at Ba Fu with his eyes, and then pulled Ba Fu's head with his hand, and said loudly, come and see, look at Ba Fu's head and melon seeds like the stigma of pistils! Bafu came to beat the classmate, and the classmate ran, and the students immediately laughed again, and laughed very happily. Standing under the window, Cao Zhen and Yu Chunhua basked in the sun with their backs against the windowsill, and said in their mouths, the stigma secretes mucus and can fix pollen, which is really interesting, and the two of them laughed...... And Dongfanghong felt even more happy because of Mr. Zhao's praise, and couldn't help but think of what his mother said before, how similar to what Mr. Zhao said today, I feel that this person is really the same as a silent plant!
