I'm writing to tell you something about the problem of food safety.
A couple of days ago,one of my classmates bought a bag of food from a
supermarket. Some roommates were invited to enjoy the food. Unfortunately,after
finishing it,all of them got poisoned and had stomachaches with their faces
pale. They were quickly sent to a nearby hospital. A doctor examined them and
gave them some medicine. They were out of danger soon after taking the
medicine.
This accident made me realize the seriousness of the food safety problem. I
sincerely hope that the whole society pay much more attention to food
safety.
