完形填空

In a small open courtyard, outside a school building, there were flowers here and there. In the sunshine，a        was lying on the grass，reading a book with        concentration. Near her，another child was carefully watering the flowers, while a third was        with his back against a tree and had a        on his knees. He appeared to be drawing or writing something on it. He was       in his task, like the first child.
      the building, there were pleasant carpeted areas. Many children were busy with their tasks in a variety of        while teachers wandered among them, talking to them,        them, and encouraging their efforts.
      I watched this scene on a morning in May years ago, it        to me that a visitor here would        have thought he had entered a formal school. He would have been even more      if he had been told that the children he was        came from different kinds of academic levels.
That        has been staying with me ever since. I have been        about some problems. Why in many schools are our children        asked to acquire skills in a way        from a real-life context（情境）? Why does a        school child so often become a defeated school failure?
Developmental psychologist Margaret Donald once said, “      of the intellectual framework (知识框架) on which we        our teaching is misleading.” In my opinion, a child learns everything in human situation. And if every child could learn in the same way as the children in the school I visited, they would develop better.
