(2018·全国卷Ⅲ)Cities usually have a good reason for being where they are, like a nearby port or river. 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.
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 warming. 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.
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.

【回答】
4.C 细节理解题。根据文章第一段第一、二句，并结合关键信息第三句“New York City, for example, is near a large harbour at the mouth of the Hudson River.”可知，纽约吸引早期移民的原因是它的地理位置，故C正确。
5.B 细节理解题。根据文章第二段倒数第二句“Of the first 20,000 people who dug for gold, 4,000 got rich.”可知，在最初挖黄金的两万人中有4,000人变富有，所以是五分之一的人变富了，故B正确。
6.B 细节理解题。根据文章最后一段第四句中的“... and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come”可知，人们离开Dawson的主要原因是听说在Alaska发现了黄金，也就是他们要去别的地方寻找发财的机会。故B正确。
7.A 主旨大意题。第一段简要介绍城市发展的原因，引出Dawson这一城市的兴起，第二段介绍了该城市兴起的原因，第三段介绍人们选择离开该城市的原因及该城市现在的状况，所以全文叙说了Dawson这个城市的兴衰。故A正确。
