1. What can we learn about the dolphins' “smiles” from the passage?
B
2. The underlined word “extrapolating” in Paragraph 4 probably means “______”.
D
3. What is the writer's main purpose in writing the passage?
C

答案： 1. B 提示:细节理解题。根据第三段中“This suggests it is a form of communication. By ‘smiling’ at each other, dolphins may stop their games from turning into real fights because of misunderstandings.”可知,海豚的微笑可能是一种交流方式。
2. D 提示:词义猜测题。reduce 意为“减少”;watch 意为“观看”;agree 意为“同意”;guess 意为“猜测”。根据画线词下文“Dolphins do open their mouths during play, which seems like communication. But I wouldn't call it a ‘smile’ because they also open their mouths in other situations, such as during aggression or when they are alone”可知,海豚在玩耍时确实会张嘴,这看起来像是在交流。但海豚在其他情况下也会张嘴,比如在攻击时或独处时,所以海豚张嘴的行为并不一定代表它们在“微笑”。结合选项可知,画线词意为“猜测”。
3. C 提示:主旨大意题。通读全文可知,本文主要讲述了海豚在玩耍时会出现类似“微笑”的表情,并介绍了科学家对这一现象的研究发现,以及下一步要对野生海豚在类似情境下进行研究,结合选项可知,选项 C“展示关于海豚微笑般表情的研究发现”是作者的写作意图。
