Then our four-member group had a and decided to do some research(调查) in a supermarket. Two of us wrote down the names of the food on the shelves(货架). The other two customers(顾客) some questions like “Do you know what green food is? ” “How often do you green food?” and so on. More than 30 customers our questions! Later each group in our class wrote a research report the topic and handed it in（交上）. Our teacher chose the ones and put them up on the wall of the classroom. was one of them! We not only learned a lot about green food but also knew how to keep healthy.
