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) 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.

(1)-(4)CBBA 解析：(1).推理判断题。题干句意:是什么吸引那些早期定居者来到纽约市的呢?根据第一段第三句话(例如纽约市,它在哈得孙河的河口的一个大港口附近。)并结合第四句可知,这个优越的地理位置使得纽约市的人口在300年的时间里从800增长到800万。所以*为C项:它的地理位置。A项:它的贸易文化。B项:它的稀少的人口。D项:它的宜人气候。这三项原文均未提及。 (2).细节理解题。题干句意:对那些第一批到达道森市淘金的人我们了解到了什么?根据第二段倒数第二句话(在第一批淘金的20,000人中,有4,000人富了起来。)可知有五分之一的人富了起来,故B项正确。 (3).推理判断题。题干句意:很多人离开道森的主要原因是什么?根据第三段第四句话第一个逗号后的部分(当他们听说在阿拉斯加州发现了新的金矿后,他们就像当初匆忙来道森市一样,又匆忙离开了这里)可推断出这些人匆匆忙忙离开这里去阿拉斯加州淘金去了,又去碰运气看能不能变富。B项“他们想去别的地方碰运气。”与原文意思相符。A项:他们觉得这个城市太拥挤了。C项:他们无法忍受这里的冬天。D项:他们缺少食物。这三项与原文不符。 (4).主旨大意题。文章第一段第一句话提出观点:一个城市之所以矗立在那里是有充分的原因的。后文以两个城市为例来论*这个观点。纽约市的兴起是因为它优越的地理位置。道森市的兴起是因为这里发现了金矿,而这座城市的衰落是因为这里没有了金矿。由此可知本文主要描述了一个城市的兴起和衰落及其背后的原因。这与A项相符。B项:加拿大的淘金热。C项:踏进荒野的旅程。D项:道森的旅游业。这三项都不是主题。
