　　Today, we're going to talk about Amazon River. You probably learned in middle school that the Nile River is the longest river in the world and it's the cradle of civilization. (16) But, more impressive, is the Amazon River, the second longest river in the world. As you know, I have spent a lot of time working along both of these rivers, doing research, filming, and sometimes just relaxing. If you ever get a chance to visit one of these rivers, go for it. However, if you have to choose between visiting the Amazon and visiting the Nile, then you should definitely visit the Amazon. In my opinion, it's way more interesting than the Nile! In fact, it's the most interesting place I've been to, and I've been everywhere, including all seven continents.

　　(17) The main reason why I think it's so interesting is that the Amazon delta is the largest tropical rain forest in the world. And where there's a rain forest, there's life. Plenty of it! The Nile flows mostly through dry desert, where there's little wildlife or plant life. Meanwhile, there's more life in the Amazon than in any other places in the world. For example, there are 500 species of mammals, one third of the world's bird population, hundreds of reptiles, 175 different kinds of lizards, up to 300 million types of insects, and immense vegetation. The trees are so dense that they form a canopy. The basin contains the Earth's richest and most varied ecosystem. It will startle your senses, your sight, your hearing, and your sense of smell.

　　Let me briefly describe for you some of the impressive creatures you'll see on the video next week. The first is the jaguar. It is the largest and most powerful cat in the western hemisphere. (18) It measures up to six feet in length and weighs up to 350 pounds. Their powerful jaws can crush a turtle shell. In the river, there are 300-pound dolphins. And not far away is the world's largest snake, the anaconda.

　　The Amazon basin is thick with vegetation, including a very dense forest of tall trees. (19) By far the most amazing thing in the basin is the treetop world. Many of the trees are 150 feet tall, with canopies exceeding 80 feet. Some scientists believe this canopy alone may contain half of the world’s species!

　　Among these species is the harpy eagle, which has a six or seven-foot wingspan and is perhaps the most powerful bird in the world. It's big enough to carry a full-grown monkey and then eat it. There is the Macaw parrot, considered by many to be the largest and most beautiful of its species. The video will illustrate what I'm talking about.

　　16. Which river is the second longest in the world?

　　17. Why does the speaker think the Amazon River is interesting?

　　18. What is the weight of the jaguar in the Amazon according to the talk?

　　19. What is the most amazing thing in the Amazon basin?

　　参考答案：

　　【小题16】B

　　【小题17】C

　　【小题18】B

　　【小题19】A

　　习题解析：

　　【小题16】听力原文中明确提到 But, more impressive, is the Amazon River, the second longest river in the world.故世界第二长的河流是亚马逊河，选项 B 为答案。选项 A 在原文中也有提到，但是 the Nile River 是世界第一长河，故排除。

　　【小题17】听力原文中提到 The main reason why I think it's so interesting is that the Amazon delta is the largest tropical rain forest in the world. And where there's a min forest, there's life. Plenty of it!由此可知，演讲人认为亚马逊三角洲有趣的主要原因是那里有世界最大的热带雨林，而有雨林的地方就会有很多生物。故选项 C 为答案。

　　【小题18】听力原文中明确提到 It measures up to six feet in length and weighs up to 350 pounds.该句中的 It 指代的即是前文中提到的美洲虎，所以亚马逊的美洲虎重达350磅。故选项 B 为答案。

　　【小题19】听力原文中明确提到 By far the most amazing thing in the basin is the treetop world.即目前为止，盆地中最令人感到神奇的就是树顶世界。故选项 A 为答案。
