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，
Li Hua
亲爱的编辑，
我写信是要告诉你关于食品安全的一些问题。
前几天，我的一个同学从超市买了一袋食品。有些室友被邀请享受食物。不幸的是，吃完后，他们都得到了中毒，肚子痛且他们的脸色苍白。他们被迅速送往附近的医院。医生检查了他们，给他们一些药。在服药后不久，他们脱离了危险。
这次事故让我认识到食品安全问题的严重性。我衷心希望全社会重视食品安全。
你的，
李华
