Currently，many problems concerning the safety of food have caused much attention．As for me，I believe at least three factors account for this issue．
   First，I observe that profits drive many food producers to commit illegal things．They aim to gain more money at the expense of consumers'health．Second，the overuse of agricultural pesticide has some bad effect on food quality．（高分句型一）The execssive pesticide bears enormous health risk for people．Furthermore，some food producers inject hormones into domestic animals so as to make them grow more quickly and thus they can turn in more profit．（高分句型二） As a result，people's health has been seriously disturbed．（分析原因）
   All in all，food safety is such a great concern，and we all should estabilsh laws and implement them effectively to avoid producing posisonous foods．（提出建议） Currently，many problems concerning the safety of food have caused much attention．As for me，I believe at least three factors account for this issue．
