海洋动物迁徙
Ocean Animal Migrations
了解许多海洋动物会进行令人惊叹的迁徙——如座头鲸在觅食地和繁殖地之间游动数千英里，海龟会回到自己孵化的那片海滩产卵——并理解这些旅程与季节性食物供应和繁殖密切相关。
Know that many ocean animals undertake remarkable migrations — humpback whales travel thousands of miles between feeding and breeding grounds, sea turtles return to the same beach where they hatched to lay eggs — and understand these journeys are linked to seasonal food supplies and reproduction

评估问题 / Assessment
如果{{name}}听说座头鲸每年从南极游到热带，能解释这是为什么吗——为了在夏天追随食物，并前往更温暖的水域生宝宝？
If {{name}} heard that a humpback whale swims from Antarctica to the tropics every year, could they explain why — that it's following food in summer and heading to warmer waters to have its baby?
