Nowadays green food is popular. We need green food and good health, not all people knew that well years ago. When I was in Grade Seven, my teacher asked us to something about green food by ourselves. We had no idea at first. Then our four-member group had a and went to do some research (调查) in a supermarket. Two of us wrote down the names of the food on the shelves. 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. 小题1: A．so B．and C．or D．but 小题2: A．learn B．plant C．make D．buy 小题3: A．game B．lesson C．discussion D．fight 小题4: A．delicious B．green C．fast D．colorful 小题5: A．asked B．told C．helped D．answered 小题6: A．buy B．sell C．give D．send 小题7: A．copied B．asked C．answered D．remembered 小题8: A．in B．about C．to D．for 小题9: A．long B．short C．bad D．excellent 小题10: A．Mine B．Theirs C．Ours D．His
