阅读短文,完成下列各题。
      Snow fell on the mountain. It snowed and snowed. The snow did not melt (融化). It became deep and
heavy. The snow on the bottom pressed (挤压) together, it became ice.
      The ice was very wide and thick. It began to move down the mountain. It was like a river of ice. It was a
glacier (冰河).
      Sometimes the glacier moved only a few inches (英寸) each day. As it moved, it took rocks and dirt with it.
It changed the land. In some places, it left hills. In some places, when the glacier melted, it made rivers and
lakes.
      A million years ago, there were many big glaciers. Glaciers covered many parts of the world. The glaciers
changed the land.
