Question

【题目】Glacier Bay is one of the most famous parks in America, located in the state of Alaska. This park in the southeastern part of the state covers more than 1 million hectares of Alaskan wilderness. It includes mountains, glaciers (冰川), bays, and even rainforests. Glacier Bay supports hundreds of kinds of animals, including many species of birds, fish, bears, whales and sea lions.

As its name suggests, much of Glacier Bay National Park is covered by glaciers. A glacier is a large area of ice that moves slowly down a slope (斜坡) or valley, or over a wide area of land. Glaciers cover more than 5,000 square kilometers of the park.

Glacial ice has shaped the land over the last seven million years. The glaciers found in the park today are what remains from an ice advance known as the Little Ice Age. That period began about 4,000 years ago.

During the Little Ice Age, the cold weather caused the ice to grow and advance. That situation continued until about 1,700s, when the climate began to warm. The higher temperatures caused the ice to start melting. That melting led the huge glacier to separate into more than 1,000 different glaciers.

The extremely tall and jagged (参差不齐的) mountains seen in Glacier Bay National Park were formed by the ice advancing and then melting over time. The melting of the ice also created water that filled in and created the many fjords (峡湾) within the park. Fjords are narrow parts of the ocean that sit between cliffs or mountains.

The huge amount of water from the melted ice killed off many kinds of plants. Vegetation returned to the area over the next 200 years. The regrowth in plants also brought back many animals to the land. This return of life to Glacier Bay is why it is sometimes called “a land reborn” by people.

【1】What is mentioned in Paragraph 1?

A. The function of Glacier Bay.

B. The climate of Glacier Bay.

C. The area of Alaskan wilderness.

D. The number of animals in Glacier Bay.

【2】What happened to Glacier Bay during the Little Ice Age?

A. Many slopes or valleys came into being.

B. The glaciers grew and advanced.

C. Different glaciers became a whole one.

D. The fjords became narrow.

【3】What is mainly discussed in the last paragraph?

A. How the water killed off the plants.

B. When vegetation returned to Glacier Bay.

C. What the relationship between plants and animals is.

D. Why Glacier Bay is sometimes called “a land reborn”.

Answer 1

【答案】

【1】A

【2】B

【3】D

【解析】冰川湾国家公园是美国最著名的公园之一，面积广大，地形复杂。正如它的名字所暗示的，大部分的公园是由冰川覆盖的。今天在公园里发现的冰川是冰川时代的小冰川期所遗留下来的东西。这一时期大约始于4000年前，持续到18世纪。后来，随着气温逐渐升高，那些极高的参差不齐的山和峡湾就是由冰川前进和融化形成的。那些融化了的冰水使许多植物灭绝，又过了200多年植被才又重新回到了这块土地，继而引来了许多动物，生命的回归使得这个地方有了“重生的陆地”之名。

【1】A 细节理解题。第一段中提到了冰川湾的位置，地形和动物种类等。没有提及它的气候和动物的数量，排除B、D项。This park in the southeastern part of the state covers more than 1 million hectares of Alaskan wilderness这句意思是说，冰川湾占了100万公顷的阿拉斯加荒地，而选项C指的是阿拉斯加荒地的面积，不是同一个概念。故排除。

【2】B 细节理解题。由文章第四段第一句During the Little Ice Age, the cold weather caused the ice to grow and advance得知，在小冰河期寒冷的天气使得冰山增长和发展。

【3】D主旨大意题。文章的最后一段主要讨论了这个地区在融化了的冰水破坏了植被200年后又重新恢复生机，成了一块“重生的土地”。
