Reading tasksYou are a producer(生产者) of “green food”——that is to say your food is certain to be healthy and safe for people’s health. It is also free of chemical fertilizers(化肥) and grown away from industrial areas(工业区) and dirty water supplies. This is the food you want to sell. The problem is that people do not know about your food and how good it is. You know that every weekend people leave the cities and go to the countryside to buy food like yours.
