Distinguished leaders, dear teachers and classmates
Good morning, I'm WangYifan from class 25, grade 2 . Today, my topic is "join hands to enhance physical fitness and prevent spring diseases".
Spring is coming, the temperature is gradually warm, and a variety of common epidemic diseases are quietly coming, as the saying goes "health is the source of revolution" only a healthy body can support our high strength of learning, so I today share about spring disease prevention knowledge
There are three main types of infectious diseases that occur frequently in schools
One is influenza, one is chicken pox, and the other is mumps. Influenza is a respiratory disease caused by influenza virus, which is highly infectious and often accompanied by fever, Varicella is an acute infectious disease caused by varicella zoster virus Mumps is a respiratory disease caused by the mumps virus, which often breaks out in schools and public places。All three diseases are transmitted by respiratory tract，if we prevent rightly these diseases can avoid.
How can we prevent these infectious diseases?
First of all, we should develop good health habits, Wash your hands and take a bath frequently, open Windows frequently, drink more water and eat more fruits to supplement vitamin c . Spray and mop the floor to avoid raising dust into the mouth and nose, pay attention to keep warm, often exercise. Exercise is especially important
Physical exercise is an important way of improving the quality of our body, we should conscientiously do gymnastics, second, to make full use of the recess ten minutes, don't always sleep in the classroom, gooutside.and take a breath of fresh air, we can also make full use of before and after school in the afternoon free time to do morning reading in the morning, for outdoor exercise.
Let us join hands to enhance physical fitness, work together to do a good job in spring disease prevention!
That's all for my speech。Thank you for listening.
