At some 2,300 miles in length, the Mississippi is the longest river in the United States. At some 1,000 miles, the Mackenzie is the longest river in Canada. But these waterways seem minute in comparison to the world’s two lengthiest rivers: the Nile and the Amazon. The Nile, which begins in central Africa and flows over 4,100 miles north into the Mediterranean, hosted one of the world’s great ancient civilizations along its shores. Calm and peaceful for most of the year, the Nile used to flood annually, thereby creating, irrigating and carrying new top soil to the nearby farmland on which ancient Egypt depended for livelihood. As a means of transportation, the river carried various vessels up and down its length. [9] A journey through the unobstructed part of this waterway today would pass by the splendid Valley of the Kings with the tombs of many of these ancient monarchs have stood for over 3,000 years. [10] Great civilizations and intensive settlement are hardly associated with the Amazon. [11] Yet this 4,000-mile long South American river carries about 20% of the world’s fresh water, more than the Mississippi, Nile and Yangtze combined.
Other statistics are equally astonishing. The Amazon is so wide at some points that from its center neither shore can be seen. Each second the Amazon pours some 55 million gallons of water into the Atlantic. There, at its mouth, stands one island larger than Switzerland. Most important of all, the Amazon irrigates the largest tropical rainforest on earth.
Questions 9 to 11 are based on the passage you have just heard.
9.What can be found in the Valley of the Kings?
10.In what way is the Amazon different from other big rivers?
11.What does the speaker say about the Amazon?

选项 A、It provides habitats for more primitive tribes.
B、It is hardly associated with great civilizations.
C、It has not yet been fully explored and exploited.
D、It gathers water from many tropical rain forests.

答案 B

解析 浏览四个选项,根据选项中出现的great civilizations,explored,gathers water,forests等词以及人称代词it可以推测,该题应该和河流与文明有关系,可能涉及河流的淡水资源、文明发源、开发利用等。题干问的是亚马逊河与其他大型河流的不同之处是什么。文中提及,伟大的文明和密集的聚居地与亚马逊河几乎没有关联,故答案为B(它与伟大的文明没有什么关联)。A项(它为原始部落提供了栖息地)和C项(它尚未被完全开发利用)在文中并未提及,故排除。文中提及亚马逊河灌溉着地球上最大的热带雨林,D项(它从热带雨林收集水分)与原文不符,故排除。
