問題詳情：

    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 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.

【分析】

這是一篇説明文。文章主要介紹了Dawson這座城市的發展原因、過程與現狀。

48．細節理解題。根據文章第一段中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.可知，人們選擇在河邊或港口設城是因為交通方便，便於做生意。而紐約就是在哈德森河口附近的一個大港口，故紐約吸引早期移民的原因是它的地理位置，故C正確。

49．細節理解題。根據文章第二段最後一句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.可知，在最初挖黃金的兩萬人中有4000人變富有，所以是五分之一的人變富了，故B正確。

50．細節理解題。根據文章最後一段中and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come.可知，人們離開Dawson的主要原因是聽説在Alaska發現了黃金，也就是他們要去別的地方尋找發財的機會。故B正確。

51．主旨大意題。第一段簡要介紹城市發展的原因，引出Dawson這一城市的興起，第二段介紹了該城市興起的原因，第三段介紹人們選擇離開該城市的原因及現在的狀況，所以全文圍繞Dawson這個城市的發展起伏。故A正確。

【點睛】主旨大意題的解題技巧：一篇文章都是圍繞着一箇中心思想或一個話題展開的，因此，有的文章中最明顯的特點之一是有一個反覆出現的中心詞，即高頻詞，也叫做主題詞。抓住了它，便容易抓住文章的中心。通讀全文可知，文章主要圍繞Dawson的發展展開，Dawson反覆出現，再根據每一段的段首句可以總結出，文章第一段通過城市發展的原因引出Dawson，第二段介紹Dawson發展的原因，第三段介紹人們選擇離開該城市的原因及現在的狀況，從而總結出文章的主旨大意。
