目前，食品安全问题引起了人们的广泛关注。一些生产厂商为了降低成本追求利润，削减了必要的安全措施，致使一些劣质或有害食品流入市场，对人们的健康产生了极大的危害。请你就此事给一家英文报刊写封信，谈谈个人看法并呼吁整个社会关注此事。
参考词汇：利润profit；安全措施safety measures 佳作欣赏
Dear Sir，
I’m writing to talk about the problems of food safety nowadays.To reduce the cost and make more profits，some food companies don’t take necessary safety measures to guarantee the food quality.As a result，more and more low--quality food flows into the market，doing a lot of harm to consumers’ health.In my opinion，food is essential to human beings.We can not live without proper food.If no notice were taken of food safety，the health of the whole nation would suffer.So I call on the whole society to take action and put an end to the low-quality food.Only in this way can we live a healthier life.
Yours truly，
Li Hua名师点睛
