本题可根据上下文语境及对水稻不同生长阶段的特征描述来选择合适的句子。
对于①处：后文提到“Let me tell you about the rice.（让我来给你讲讲水稻）”，所以此处应该是引出水稻，A选项“It is rice（它是水稻）”符合语境。
对于②处：前面提到“In spring, farmers plant it in the field.（春天，农民把它种在田里）”，结合图片及常识，夏天水稻会有绿叶和强壮的根，B选项“it has green leaves and strong roots（它有绿叶和强壮的根）”符合夏天水稻的特征。
对于③处：前面提到“In autumn, it has many seeds!（秋天，它有很多种子！）”，结合常识，我们吃的是水稻的种子，C选项“We eat the seeds of it（我们吃它的种子）”符合语境。
