The first lesson of school health is really a very good program. There are three "good friends" in the program. They are both children and parents' "good friends". The first "good friend" is a healthy snack. With the progress of the times, people's living standards have improved, and more and more people are obese, especially children. Every family has a little emperor and princess, who is loved by parents and elders, and all kinds of candy and drinks are in short supply. I think parents and children who watch this program will realize the wrong diet and learn how to choose healthy snacks. Let our children and families eat healthier. The second "good friend" is sports. Nowadays, under the temptation of high-tech mobile phones, people just play mobile phones when they go home, ignoring communication with their families and taking care of their children. We should all learn to put down our mobile phones, enjoy good parent-child time together, and take a walk with our families after meals to effectively prevent obesity. You can read books and chat with children at night. Every weekend, the whole family can go out and do some high-intensity outdoor sports or meaningful activities. Exercise can prevent obesity and enhance feelings. Companionship is the best and longest expression of love. The third is to make friends with people who are in a bad mood. In other words, learn to control your bad emotions. We should all learn to actively communicate with others, first realize our own shortcomings, communicate and talk, so as to better release our bad mood. No matter how stressful it is, parents should not bring bad feelings home. Home is our warm harbor, and family members are our closest people. We should talk to each other well, with a gentle tone and slow speech. When there are things and differences of opinion, we should communicate more, communicate well and try to smile. Parents are a mirror of their children. Your words and actions directly affect your children, so parents should set an example. A good family atmosphere is very important. Children grow up in a warm family environment full of positive energy, and they will grow into a teenager with love and sunshine in their hearts. As a new generation of socialist successors, we should not only study hard, but also have a healthy body. Only when everyone has a healthy body can the country be stronger. A strong teenager makes a strong country!
