One day, a bear and a deer are playing a game of catching beans. The bear wants to put a bean in his nose. The deer saw it and said, "Bear, this is very dangerous. If you can't get it out, the beans will swell up and the nasal cavity will be inflamed. If it is serious, you have to have surgery to take it out. " The bear stopped in horror and spat at his small tongue. He said shyly to the deer, "Thank you, but for your warning, I hurt myself again." In the next few days, the deer always reminds the bear of something. The next day, he reminded Bear: Don't touch the socket with your hands, and don't put anything else in the socket, lest you get an electric shock. On the third day, remind the bear: stay away from fire and knives, and be careful of burns and cuts. If there is a fire, cover your nose and mouth with a wet handkerchief or towel first; If you accidentally cut yourself, tie up the bleeding place with a clean cloth and call 120 or notify your parents. On the fourth day, remind the bear: don't climb high, let alone climb the window, or fall down. One month after the fifth day, the bear stopped doing dangerous things. With the help of the deer, he became a good baby that reassured his parents at home and on the road. In kindergarten, he became the teacher's favorite child.
