These are the bad habits of some students in my class. We should: wash our hands before eating; Don't eat popsicles on trees; Throw the paper wiped with your nose into the dustbin; Take a sip and go home to drink water; Don't buy unclean things outside. ...
Then why is this? If you don't wash your hands before eating, the bacteria on your hands will be eaten by yourself, which may cause stomach pain and other conditions; Lick the popsicles on the tree like popsicles. It's very cold. You may catch a cold and have a fever. When you are thirsty, go to the toilet to drink tap water. There are many bacteria in tap water that are not disinfected, which may cause diarrhea. Eating unclean things outside may cause cancer and so on. ...
Students must develop good living habits and be healthy people!
