2017-2018学年高一英语(北师大版) 必修三全册教学案Killer whales have the second­heaviest brains among marine mammals (after Sperm whales, which have the largest brain of any animal). They can be trained in captivity (囚禁；关押) and are often described as intelligent, although defining and measuring “intelligence” is difficult in a species whose environment and behavioral strategies are very different from those of humans.Killer whales imitate others, and seem to deliberately teach skills to their kin. Off the Crozet Islands, mothers push their calves onto the beach, waiting to pull the youngster back if needed.People who have interacted closely with killer whales offer numerous anecdotes demonstrating (证明) the whales' curiosity, playfulness, and ability to solve problems. Alaskan killer whales have not only learned how to steal fish from Iong lines, but also have overcome avariety of techniques designed to stop them, such as the use of unrated (未分级的；未征税的) lines as decoys. Once, fishermen placed their boats several miles apart, taking turns retrieving (恢复；取回) small amounts of their catch, in the hope that the whales would not have enough time to move between boats to steal the catch as it was being retrieved. A researcher described what happened next: The killer whale's use of dialects and the passing of other learned behaviours from generation to generation have been described as a form of animal culture.Section_ⅠWarm­up__&_Lesson_1_—_Pre­reading[原文呈现]VIKING VOYAGES①TO AMERICAThe Vikings②were the first Europeans to reach America③.
