(原创) Scientists have long known that elephants are clever. They can solve problems, they talk to each other, and have long memories. But researchers were surprised at the way two Asian elephants recently showed off their understanding of an unusual tool—a hose(水管).
★ They have been seen using tree branches to drive flies away. Although their size is big, they're also able to peel bananas.
Now researchers report that a clever Asian elephant named Mary has learned how to shower herself using a hose. That may not seem amazing, but one of the scientists said that for animals, a hose—a flexible tube with running water coming out of the end—is "very complex(复杂的)".
Mary has learned to grab the hose in different ways to clean different parts of her body. She grabs the end of the hose to clean areas she can reach easily. But when Mary wants to wash her back, she grabs the hose a few feet away from the end. This allows her to swing the hose up to spray(喷) water over her back with a movement like a lasso.
Anchali is a 12-year-old Asian elephant who often gets sprayed down by zoo workers in the area next to Mary. Anchali has also learned about hoses. But she doesn't use a hose to shower. Instead, she has thought out how to make the water stop coming out of Mary's hose.
While the researchers were watching Mary one day, they were surprised to notice Anchali grabbing Mary's hose, folding it into a sharp bend(弯曲), and then squeezing it tightly. The water from Mary's hose stopped.
Both elephants show clever use of a complex tool. But it will take more research to learn whether Anchali is playing her tricks on purpose.

训练1 【语篇解读】本文是一篇说明文,讲述了研究人员发现,两只亚洲象对于使用水管有着自己的认知与理解,实验表明它们已经可以知道水管是如何运作的了。
1. A 补全文章题。根据第一段"But researchers were surprised at the way two Asian elephants recently showed off their understanding of an unusual tool—a hose."和下文"They have been seen using tree branches to drive flies away."可知,本段讲述的是亚洲象使用工具的事情,故选 A。
2. D 段落大意题。根据第三段"for animals, a hose—a flexible tube with running water coming out of the end—is 'very complex'"可知,尽管人们认为用水管不是难事,但是在动物眼里,水管对它们来说太复杂了,因此大象能够知道水管是如何出水的很令人惊奇,故选 D。
3. C 推理判断题。根据第五段可知,虽然安查理不用水管洗澡,但是它知道怎么阻止水管里的水流出来,由此可知大象足够聪明来使用工具,故选 C。
4. B 标题归纳题。结合第一段"But researchers were surprised at the way two Asian elephants recently showed off their understanding of an unusual tool—a hose."以及文章内容可知,本文主要讲述了研究人员发现,两只亚洲象对于使用水管有着自己的认知与理解,实验表明它们已经可以知道水管是如何运作的了,故选 B。
