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?
