2018·全国卷Ⅲ·阅读理解B篇——对接课标主题：主要国家地理概况
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 snow-covered 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.
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.

(六)在语境中赏表达之美
1．(赏结构之美)People settle in these places because they are easy to get to and naturally suited to communications and trade.

to understand
with
2．(赏用词之美)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.
赏析：城市里挤满了(was crowded with)失望的(disappointed)而又没有兴趣定居下来(with no interest in settling down)的人，所以一听说阿拉斯加发现了黄金，迅速(as quickly as they had come)就离开了。寥寥数词把道森这个成也黄金败也黄金的城市的迅猛崛起和急速衰败表达的准确生动、传神巧妙。
3．(赏意境之美)They travelled over snow-covered 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 once closed the path, killing 63 people.
赏析：白雪皑皑的群山(snow-covered mountains)、蜿蜒数百英里的冰河(hundreds of miles up icy rivers)、覆盖着30英尺厚的雪的道路(thirty feet of wet snow)、曾经让63人遇难的雪崩，沿途所有凶险都挡不住淘金者前进的脚步，成就了一个城市的快速崛起，令读者唏嘘。
