Many students drown in the river every year in our country. According to incomplete statistics, there are about 57,000 people drowning in China every year, of which 56% are teenagers and children, and the number is quite large. Although schools and families often publicize the dangers of swimming in the river without permission and prohibit swimming in the river without permission. However, it is inevitable that teenagers will drown. This is because students lack a certain sense of security, think that they are good swimmers and overestimate their abilities. They think it shouldn't be a problem just to tread water. It is precisely because of the lack of safety awareness of correct data that drowning accidents occur. Then, the weather in summer is the hottest. When the weather is hot, many students want to go swimming and play with water to cool down. It is foolish to let your life end here for the sake of temporary coolness. Also, there is a certain relationship with parents. Some parents spoil their children very much, and some parents think that their children will have no problem as long as they go to some shallow waters to play with water. There is no doubt that as long as you play in the river without permission, drowning accidents will happen. Many children die from drowning accidents every year in our country. Therefore, I hope that schools and families must do a good job of publicity and prohibit students from swimming in the river. Parents must also supervise their children and never let them play in wild waters. As students, we should also establish a correct sense of safety, and don't swim in the river without permission.
