Alaska
In 1959 Americans welcomed Alaska into the Union as the 49th state,symbolizing a change of attitude from that held in 1867, when the peninsula（半岛）was purchased from Russia.Then, most Americans had little interest in 1,500,000 square kilometers"of icebergs and polar bears"-beyond Canada's western borders,far from the settled areas of the United States.
In those sections of the state which lie above the Arctic Circle,Alaska still is a land of icebergs and polar bears.Ice masses lie buried in the earth.From early May until early August,the midnight sun never :ts on this flat,treeless region,but the sun cannot melt the icy soil more than two-thirds of a meter down.
Alaska is America's largest state,but only about 325,000 people live there.According to estimates, 800，000 hectares of its land area are fit for plowing but only about 640,000 hectares are being cultivated?
Arctic Alaska has been the home of Eskimos for countless centuries.It is believed that the Eskimos moved there from Mongolia or Siberia,probably crossing Bering Strait,named for Vitus Bering,the Danish ea captain who discovered Alaska on his voyage for Russia in 1741.The Eskimos are the state's earliest known inhabitants.Russian fur traders established settlements but,by the time Alaska was sold to the United States,most of the traders had departed.
In 1896 gold was discovered near the Klondike River in Canada just across the Alaskan border.Thousands of Americans rushed to the region on their way to Klondike;some never returned.Alaska was ,ever completely cut off again,although even today transportation is a major problem.There are only two motor routes from the US mainland,and within the state,every town has its own airfield.Planes fly passengers,mail and freight to the most distant villages.
The gold that changed life so suddenly for Alaska was soon ended,and although many stories about fining camps have become part of American literature,the gold from Alaskan earth contributed less to ,economic progress than the fish from Alaskan waters.The fish?caught in a single year range in value from $80 million to $90 million.Fur一bearing animals are plentiful in the forests and streams,and valuable fur seals inhabit the waters.After fishing,the state's chief industry is lumber and the production of wood pulp（纸浆）.In recent years,Alaska's single most important resource has become oil.The state also has large deposits of coal,copper,gold and other minerals.What is mainly responsible for the economic growth in Alaska now?A:Gold. B:Oil.C:Fish. D:Fur.
选项 What is mainly responsible for the economic growth in Alaska now?
A:Gold.
B:Oil.
C:Fish.
D:Fur.
答案 C
解析 本文主要讲述了阿拉斯加半岛的地理位置、地貌特征、可耕种面积、土著居民以及主要经济产业等内容。
由文章第一段第一句话“…when the peninsula was purchased from Russia.”可知，阿拉斯加半岛曾是俄罗斯的一部分。故选D。
由文章第三段中“800,000 hectares of its land area are fit for plowing...”可知，阿拉斯加州的一些土地适合耕种。故选B。
由文章第四段第三句话“The Eskimos are the state' s earliest known inhabitants.”可知，爱斯基摩人是阿拉斯加州的土著居民。故选A。
由文章第五段最后两句话“.and within the state, every town has its own airfield.Planes fly passengers, mail and freight to the most distant villages.”可知，阿拉斯加州的主要交通工具是飞机。故选C。
由文章最后一段可知，虽然成千上万的美国人奔赴阿拉斯加州淘金，但是阿拉斯加州的金子对经济发展的贡献远不如阿拉斯加州水里的鱼。那里一年捕到的鱼能卖8 000万到 9 000万美元。故选C。
