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 carries about one fifth of the world’ s fresh water.
B、It has numerous human settlements along its banks.
C、It is second only to the Mississippi River in width.
D、It is as long as the Nile and the Yangtze combined.

答案A

解析 浏览四个选项,根据选项中出现的world’s fresh water,banks,Mississippi River,Nile and the Yangtze等词可以推测,该题与世界上的著名河流有关,可能涉及河流的淡水资源等。题干问的是讲话者提到与亚马逊河相关的什么内容。短文中提到,这条4000英里长的南美河流承载着世界淡水总量的20%,比密西西比河、尼罗河和长江加起来的总和还要多,故答案为A(它承载着世界淡水总量的五分之一)。短文中提到,伟大的文明和密集的聚居地与亚马逊河几乎没有关联,故排除B项(亚马逊河两岸有许多人定居)。C项(亚马逊河在宽度上仅次于密西西比河)在短文中并未提及,故排除。D项(亚马逊河的长度是尼罗河和长江加起来那么长)明显不符合常识,尼罗河才是世界第一长河,故排除。
