评价指标 建议
人称转换准确性:原文中第三人称（blue whales/a blue whale）均换成第一人称,无转换错误。
内容完整性：涵盖原文关键信息，无信息遗漏。信息顺序可适当调整，但逻辑要通顺，符合第一人称叙述的自然感。
语言流畅性：改写后的句子读起来顺畅，符合英语表达习惯，没有生硬、断裂的感觉。避免因人称转换出现语法错误，影响表意。
情感与角色契合度：语言要符合蓝鲸自述的特点，增强第一人称的代入感。体现出蓝鲸的“诉求”，让读者能体会到蓝鲸的价值和保护的必要性。
Hello everyone! My name is Billy the Blue Whale. I am the largest and heaviest animal on earth. I can weigh as much as 200 tons. I’m heavy, but I love swimming. I live in all oceans except the Arctic Ocean. My favourite food is some of the tiniest animals in the ocean. I can eat around four tons of these tiny animals a day.
I can live up to 90 years. When I die at sea, I become food for many kinds of animals living in and around the sea. This food lasts for over a year and it helps to create a lively and healthy ecosystem. I play an important role in the world, so please protect me!
