阅读理解     Do potatoes play a small role on your dinner table? If so, let's have a big change! Potatoes are becoming China's fourth staple food (主食) after rice, wheat and corn. Using potatoes as a staple can make our diets healthier and more balanced (均衡的).     They are good for us in many ways.     Potatoes are nutritious (有营养的). They are rich in vitamin C.
