Question

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 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.

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

1.The snow that fell on the mountain _______ before glaciers were formed.

A. became river    B. melted    C. became ice    D. turned to rain

2.Which of the following does this story lead you to believe?

A. There are not as many glaciers as there used to be.

B. Glaciers do not change the land as they move over it.

C. Glaciers are found only in warm places.

D. The earth is getting warmer and this leads to the melting of glaciers.

3.The main idea of the whole story is that __________.

A. snow is heavy    B. the high land never changes

C. glaciers changed the land    D. snow became ice to form a glacier

Answer

1.C

2.A

3.C

【解析】本文主要讲述的是冰河的形成及冰河对环境带来的变化与影响。

1.细节理解题。题意：落在山上的雪在冰河形成之前怎样变化？A. became river变成河；B. melted融化；C. became ice变成冰；D. turned to rain变成雨水。由短文第一自然段里的： It became deep and heavy. The snow on the bottom pressed together., it became ice.可知，雪落在山上，不融化，他们变成冰，然后冰开始从山上移动下来，就是冰河。故选Ｃ。

2.推理判断题。题意：故事引导你相信下面哪一个？A. There are not as many glaciers as there used to be.现在没有以前那么多的冰河了；B. Glaciers do not change the land as they move over it.冰河从陆地上移动时不会改变它；C. Glaciers are found only in warm places.只有在暖和的地方才会发现冰河；D. The earth is getting warmer and this leads to the melting of glaciers.地球变暖使得冰河的融化。由短文最后一段可知，地球上有些冰河现在融化了，所以现在的冰河没有以前那么多了。故选Ａ。

3.主旨大意题。题意：整个故事的主要意思是什么？A. snow is heavy雪很大；B. the high land never changes高高的陆地从来不改变；C. glaciers changed the land冰河改变陆地；D. snow became ice to form a glacier雪变成冰然后形成冰河。短文主要讲述的了冰河的形成及其对环境的改变。故选Ｃ。
