People settle in these places because they are easy to get to and naturally suited to communications and trade. New York City, for example, is near a large harbour at the mouth of the Hudson River. Over 300 years its population grew gradually from 800 people to 8 million. But not all cities develop slowly over a long period of time. Boom towns grow from nothing almost overnight. In 1896, Dawson, Canada, was unmapped wilderness (荒野)．But gold was discovered there in 1897, and two years later, it was one of the largest cities in the West, with a population of 30,000.‎ ‎[2]Dawson did not have any of the natural conveniences of cities like London or Paris. People went there for gold. They travelled over snowcovered mountains and sailed hundreds of miles up icy rivers. The path to Dawson was covered with thirty feet of wet snow that could fall without warning. An avalanche (雪崩) once closed the path, killing 63 people. For many who made it to Dawson, however, the rewards were worth the difficult trip. Of the first 20,000 people who dug for gold, 4,000 got rich. About 100 of these stayed rich men for the rest of their lives.‎ ‎[3]But no matter how rich they were, Dawson was never comfortable. Necessities like food and wood were very expensive. But soon, the gold that Dawson depended on had all been found. The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they left Dawson City as ‎ quickly as they had come. Today, people still come and go — to see where the Canadian gold rush happened. Tourism is now the chief industry of Dawson City — its present population is 762.‎ 语篇解读：本文是一篇说明文。文章主要介绍了加拿大城市——道森市的历史、发展与现状。‎ ‎1．What attracted the early settlers to New York City?‎ A．Its business culture.‎ B．Its small population.‎ C．Its geographical position.‎ D．Its favourable climate.‎ 解析：选C　细节理解题。根据第一段第二、三句“People settle in these places ... New York City, for example, is near a large harbour at the mouth of the Hudson River.”可知，纽约市吸引早期定居者之处就是它靠近哈德逊河入海口，交通和贸易便利，所以是它的地理位置吸引了早期的定居者。故选C。‎ ‎2．What do we know about those who first dug for gold in Dawson?‎ A．Twothirds of them stayed there.‎ B．One out of five people got rich.‎ C．Almost everyone gave up.‎ D．Half of them died.‎ 解析：选B　细节理解题。根据第二段倒数第二句“Of the first 20,000 people who dug for gold, 4,000 got rich.”可知，在最先的两万名淘金者中，有4 000人变得富有了，即有五分之一的人变得富有了。故选B。‎ ‎3．What was the main reason for many people to leave Dawson?‎ A．They found the city too crowded.‎ B．They wanted to try their luck elsewhere.‎ C．There were unable to stand the winter.‎ D．They were short of food.‎ 解析：选B　细节理解题。根据最后一段中“The city was crowded ... new gold discoveries in Alaska, they left Dawson City as quickly as they had come.”可知，人们离开道森去阿拉斯加碰运气了。故选B。‎ ‎4．What is the text mainly about?‎ A．The rise and fall of a city.‎ B．The gold rush in Canada.‎ C．Journeys into the wilderness.‎ D．Tourism in Dawson.‎ 解析：选A　主旨大意题。文章第一段简要介绍城市发展的原因；第二段介绍了道森兴起的原因；第三段介绍了道森的衰落和现状，由此可知，文章主要以加拿大城市道森为例讲述了城市的兴衰。故选A。‎ 学习目标 ——题后把脉规律，练后得法理解更透 主旨大意技法(5)——利用正确选项的三大特征解题 ‎(1)涵盖性强，覆盖全文；‎ ‎(2)确定的范围恰当，既不太大，也不太小；‎ ‎(3)精确性强，不会改变语言表意的程度及色彩。‎ 以上面文章及第4题为例：文章第一段简要介绍城市发展的原因，并引出道森这一城市的兴起(rise)；第二段介绍了道森兴起的原因；第三段介绍了道森的衰落(fall)和现状。A项(The rise and fall of a city.)符合上面讲的三点。‎
