One afternoon in midsummer, the burning sun shone on the earth, and the weather was very sultry. Sister Liu hung down, Xiaohua curled up listlessly, and the grass on the grass hung its head. They all seem to say, "Oh, it's too hot!" "Even if people sit in the house, they are sweating all over. Several naughty pupils couldn't resist the temptation of cold water and jumped into the river to take a bath together. The more they swim, the more they get carried away. Who knows, the weather is changeable, and the hot sun just now has turned into a dark cloud. Soon, it began to rain cats and dogs. Because these young students swim too far away from the river bank, it is difficult to return for a while. They swam and swam so hard that they felt weak. Seeing that the river bank is close at hand, they can't get there no matter how hard they struggle. It rained harder and harder, and the river rushed, and the poor pupils were flooded and finally washed away. Why did such a tragedy happen? Please think it over. In fact, it is ok to go swimming occasionally in hot weather. The key is the question of "who to swim with and how to swim". So, what should you pay attention to when swimming? First of all, students must take care of each other and care for each other. Don't play with each other or deliberately play tricks on each other. If someone wants to go ashore early, tell other students so that everyone won't worry. However, we'd better go swimming together, swim together and go home together. Secondly, you should pay attention to rest when swimming, don't swim long distances, don't stay away from your partners, and take a collective rest after swimming for a while. If you feel unwell, you should inform your partner and go ashore to rest. Watch your companions swimming on the shore and pay attention to their safety. Finally, we can't swim and snorkel, let alone dive longer and farther than each other. If you do this, you will often have problems. Even if you want to snorkel, you should do it under the guidance of teachers and parents. If all the above students have done these things, drowning is impossible. Students, let's take this drowning accident as a wake-up call and keep ringing in our ears!
