Question

【題目】Snow falls on the mountain. It snows and snows. The snow doesn't melt(融化)．It becomes deep and heavy. The snow on the bottom pressed together becomes ice.

The ice is very wide and thick. It begins to move down the mountain. It is like a river of ice. It is a glacier(冰河)．

Sometimes the glacier moves only a few inches(英寸)each day. As it moves，it takes rocks and dirt with it. It changes the land. In some places，it leaves hills. In some places，when the glacier melts，it makes rivers and lakes.

A million years ago，there were many big glaciers .Glaciers covered many parts of the world. The glaciers changed the land.

Glaciers are still at work today. A glacier in the north of Canada is cutting a new path(道路)down the side of a mountain. This glacier will change the land，too.

【4】C

【解析】本文敘述了山上的雪不能融化變成了冰，冰沿著山下來又變成了冰河，由于冰河的移動又改變了陸地。

【1】細節(jié)理解題。根據The snow on the bottom pressed together becomes ice.可知，山上的雪變成了冰，故選C。

【2】推理判斷題。根據A million years ago，there were many big glaciers .Glaciers covered many parts of the world. 可知，在幾百年前冰河比現在要多。故選A。

【3】細節(jié)理解題。根據Sometimes the glacier moves only a few inches(英寸)each day. 可知，有時，冰河每天移動幾英寸，故選C。

【4】主旨大意題。根據短文的內容可知由于冰河的移動改變了陸地。故選C。
