They gave each group a selection of transparent (透明的) containers with meatball treats inside. Each box could be opened by twisting or pulling a particular lid or handle.”可知,科学家给水獭提供了一些透明的容器,里面装有肉丸作为奖励。每个盒子都可以通过扭转或拉动特定的盖子或手柄来打开。故选C。 2.D　推理判断题。根据文章第三段“The researchers found that if one otter cracked the puzzle, its closest friends quickly solved it, too. The findings provide evidence of ‘social learning’—animals can learn from each other.”可知,如果一只水獭解开了谜题,它的亲密朋友也能很快解开它,由此可推测水獭会将知识教给其他水獭。故选D。 3.D　细节理解题。根据文章倒数第二段“‘Our study is the first to show evidence of social learning and long-term memory in Asian short-clawed otters, which may be good news in terms of their adaptability and future survival,’ said Alex Saliveros, lead author of the Centre for Ecology and Conservation on Penryn Campus in Cornwall.”可知,Alex Saliveros认为研究首次证明了亚洲短爪水獭具有社会学习和长期记忆的能力,这从它们适应环境和未来生存的角度来看可能是个好消息。由此可知,研究结果有意义是因为其表明社会学习和良好的记忆力对水獭的生存是有益的。故选D。 4.B　主旨大意题。根据文章第一段“Asian short-clawed otters (水獭) can teach each other how to solve puzzles to get food, according to a new study that took place in England.”以及全文内容可知,文章主要介绍了一项在英国进行的新研究。该研究发现亚洲短爪水獭具有社会学习和长期记忆的能力。选项B“Puzzled otters learn from each other”(困惑的水獭互相学习)准确地概括了文章的主要内容,即亚洲短爪水獭能够互相学习如何解决谜题。故选B。 B 【文章大意】 本文是一篇说明文。研究表明人们在学习时通过做手势能更好地记住词汇。文章介绍了这一研究开展的过程以及手势在学习中发挥的重要作用,且图片和手势可能对孩子都有帮助。 5. ... ...
