3. What female physiological knowledge do boys need to know?
What do boys need to know about women's physiology? It seems that the little boy knows a lot Sometimes boys who really love you are more attentive than girls, and they all remember the day when their period is allowed. Don't cold clothes, don't make people angry. There are always a few days in a month, so what to do. It's actually quite cute.
Girls really need careful care at this time. Too much bleeding is no joke, otherwise how can physical education class be allowed to ask for leave at this time? There must be a reason for this benefit, isn't there? Where can there be a comfortable and good day for nothing? A large part of women's physiological knowledge is used as adults. The purpose of life preparation is for the sake of the next generation of your family, and you must also study the female physiological knowledge class well, right?
Haha, I feel that boys who are not learning well now are great. But there are also cute styles, and my girlfriend and aunt are still chasing you and asking what's wrong? What's the matter with you? Why don't you care about me? Haha, this is also worrying about our hostess to death, right? Still helpless ~ at least the age at which you can fall in love should be above junior high school, don't be too naive, don't you think? Otherwise, girls will be scared away by you. There's no harm in taking a physical health class.
Girls have a few days every month when their physical resistance is relatively poor. We male students must understand this. This stage is particularly easy for girls to feel uncomfortable. You can buy some brown sugar and snacks to coax your girlfriend. And be gentle with girls, for the first time.
Because that membrane, which is also a female physiological structure, gave it to you and punctured a piece of meat. There is a blood hole, at least buy a menstrual towel or something in advance. Prepare, clean, handle, and then proceed with the steps. Don't get infected, it will be bad. Especially in summer, when the blood is strong. Because if you are a responsible man, you will be responsible for this woman for life because you have done it. Or owe this woman a lifetime, even if she can't be together in the end.
It is not easy for everyone. There's nothing wrong with being nice to your woman. You don't want to carry more in your life, do you? Now there is a physical education health class in the school. In junior high school, our school was in the biology class, and it was always taught separately for men and women. I feel good. I am not a biology teacher or a doctor. I didn't say anything surprising, it was all common sense. But it is not easy for boys to make snacks well.

5. What should girls pay attention to when watching the game?
Whether attending the school sports meeting or watching other sports performances or various sports competitions, girls' spare time can be enriched.
While appreciating the superb skills of athletes, we can also feel their fighting spirit and tenacious quality. But to participate in such activities, girls must pay attention to etiquette and be a civilized audience.
You need to pay attention to these manners when watching the game: 1. Get there on time.
Generally, a ball game will arrive a few minutes earlier than the scheduled opening time, so as to sit in the audience and wait for the game to start as soon as possible. If you are late for some reason, you should enter quietly, and bend over to walk when you enter, so as not to block the line of sight of other spectators.
2。 Don't block other people's sight.
If you wear a hat with a high or wide brim, you should take it off after entering the venue to avoid blocking the view of the audience behind you. If you are watching the game in an open-air stadium, you can wear a sun hat to protect yourself from the sun, but it is also advisable not to block others' sight.
After sitting down, don't often shake from side to side or walk back and forth in the stands, which will hinder the audience in the back row from watching the effect. 3。
Sit in a civilized manner. After sitting down, don't put your feet on the front seat, and don't put your feet on the back of the front seat for comfort.
This behavior is extremely disgusting in public. 4。
No noise, no noise, no booing. As an audience, don't speak loudly, comment or laugh loudly while watching.
When athletes make mistakes in performances or competitions, they are not allowed to whistle, hiss, throw things or swear. 5。
It is necessary to maintain the public health of venues. No spitting, throwing fruit stones or packaging bags.
Don't throw empty cans, scraps of paper, peels and garbage into the competition venue at will, which will affect the competition. 6。
You should watch the game in a fair and competitive manner. Don't be partial to your own side, don't be hostile to your opponent, treat both sides equally and be fair.
Don't do anything that harms the dignity and personality of the country. 7。
Exit in order. At the end of the performance or competition, don't crowd and leave in a hurry to avoid accidents due to crowded people.
Don't block the athletes or their vehicles after the game. In addition, don't leave the stadium at will, otherwise it will not only affect the viewing mood of other spectators, but also disrespect the athletes.
6. Primary school students' sports knowledge
Common sense of physical exercise for primary school students
Common sense of primary school students' physical exercise common sense of primary school students' physical exercise common sense puts practical activities in the first place and emphasizes strengthening physical fitness through concrete exercise, which is beyond reproach. However, exercise is not a simple physical activity. Only by paying attention to learning knowledge and mastering skills in sports can the effectiveness of physical exercise be improved. But some common sense of physical exercise should be paid attention to-
1, explain the characteristics and significance of various sports activities to children. For example, track and field activities mainly rely on strength and speed, and ball activities require higher sensitivity and bounce, so that children can gradually understand some common sports.
2. Teach primary school students some knowledge and skills of common sports, and guide students to practice correctly. For example, what preparatory activities should be done before exercise, and what finishing activities should be done after exercise, such as starting, accelerating, running on the way, running in corners, sprinting at the finish line, etc. Playing basketball, passing, dribbling, shooting, defending, etc.
3. Let children know which sports they are suitable for. Because of the low level of physical development and poor cardiac endurance, it is not suitable to do long-distance running, weightlifting, rings, long-term handstand and other sports, but should choose those sports with light load, such as games, simple gymnastics, small ball games and so on.
4, teach children some of the most basic rules of sports competitions, such as listening to the password when starting, not hitting people when playing, and not ranking when playing. These are the basic conditions to ensure the smooth progress of sports competitions and let children know something. Some children have special talents in a certain sport or activity. Parents should let their children decide whether to continue training, so as to develop their professional skills and become sports seeds. However, parents have the responsibility to help their children, think and discuss sports training with them, and give them some care and support.
5. Teach children to proceed from reality, make reasonable arrangements and step by step. The amount of exercise should be gradually increased from small to large, and the movements should be from simple to complex, from easy to difficult, so that the body of primary school students can have a gradual adaptation process. Because the physical strength of primary school students increases with age, the amount of exercise also increases with age.
Childhood is the fastest stage of human growth and development, and guiding children to exercise from an early age can lay a healthy foundation for them. To achieve good health, it is necessary to develop the body in an all-round way, constantly improve metabolism, enhance the functions of respiratory organs and blood circulation organs, improve the flexibility and stability of the central nervous system, develop well-proportioned and robust muscles, and cultivate physical qualities such as speed, dexterity, strength, endurance and flexibility. In order to achieve the above requirements, we must actively carry out physical exercise and carry out diversified sports activities such as games, gymnastics, running, jumping, throwing, balancing, crossing obstacles, swimming, skating and small football according to children's anatomical and physiological characteristics. In childhood, the skeletal system grows rapidly, and the content of minerals in bones is less, but there are more organic substances, so the bones are fragile and easy to deform, which is not suitable for physical exercise with excessive burden, such as lifting weights or carrying heavy objects. Children's spine is elastic, but their muscles and ligaments are weak. If they sit up straight and bend their backs, it is easy to deform their bodies. Therefore, children should always correct their sitting posture and do gymnastics, such as sit-ups and stick exercises, to strengthen the strength of spinal muscles and ligaments. Children's muscle development is weak, which is not suitable for monotonous and long-term exercise, nor for keeping a posture for a long time, and will be very tired. Their cerebral cortex is easily excited and tired. If they do the same action repeatedly for a long time, they will lose interest and lead to distraction. Therefore, when exercising, we should try to focus on the central requirements and make the activities diversified and competitive. Only in this way can we be full of energy and concentrate. In addition, in order to correct the weakness of children's growth and development, we should adopt the practice of developing backward muscle groups. The regulation function of children's cardiovascular system is unstable, and the rhythm is not as good as that of adults. Therefore, when exercising, we should avoid tense and continuous exercise, and should not do excessive breath-holding exercise or do static exercise for too long, otherwise it will overload the heart and damage the body. Children with dysplastic respiratory organs should take exercise such as swimming and running to increase their vital capacity and promote the growth of respiratory organs. In short, children should be given comprehensive physical exercise from an early age to make their bodies develop faster and better.
