Dear editor，
Im 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。
Yours，
