Hell everyne! My name is Billy the Blue Whale. I am the largest and heaviest animal n earth. I can weigh as much as 200 tns. I’m heavy, but I lve swimming in the cean, and many peple think it is ne f the mst beautiful things t see.I live in all ceans except the Arctic Ocean. I can eat arund fur tns f the tiniest animals in the cean a day.
转折逻辑：用 “but” 连接 “heavy（笨重 ）” 和后续动作，反过来促使我们从文本找 “看似矛盾、实则体现蓝鲸特点” 的内容。原文 “Many peple like watching blue whales swim” ，所以学生需要提炼出 “lve swimming（热爱游泳 ）” 这类表达，理解 “虽笨重却灵活 / 优美” 的反差，强化 “转折连词” 用法 。
I’m heavy, but I lve swimming in the cean, and peple think it is ne f the mst beautiful things t see.
I can eat arund fur tns f the tiniest animals in the cean a day.
文本中 “eat sme f the tiniest animals... arund fur tns f these a day” 是分散信息，我们需要整合为 “arund fur tns f the tiniest animals in the cean a day” ，训练 “提取关键信息 + 连词成句” 的能力 。也可以看作是需要我们精准定位代词所指代的内容，然后进行替换，以使句子更加简练。
