The Blue Whale
The blue whale is the largest and heaviest animal on earth. It can weigh as much as 200 tons. Many people like watching blue whales swim, and they think it is one of the most beautiful things to see. Blue whales live in all oceans except the Arctic Ocean. They eat a lot, but they eat some of the tiniest animals in the ocean. A blue whale can eat around four tons of these a day.
Blue whales can live up to 90 years. When a blue whale dies at sea, it becomes 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. Blue whales play an important role in our world, so we must protect them.

Language points
1. Blue whales can live up to 90 years. 蓝鲸的寿命可达 90 年 。
live up to 达到；符合（期望等）；活到（某一年龄、岁数等）
例如：
He always lives up to his parents' expectations. 他总是不辜负父母的期望。
【拓展】同义词
reach 达到（某一数量、程度、年龄等 ）；在表示活到某一年龄时，可与 “live up to” 替换。
例如：
Some trees can reach a height of 30 meters. 有些树能长到 30 米高 。
Some people can reach 90 years old. 有些人能活到 90 岁 。
2. When a blue whale dies at sea, it becomes food for many kinds of animals living in and around the sea. 当一头蓝鲸在海洋中死去时，它会成为生活在海洋里及海洋周边的多种动物的食物。
living in and around the sea 整体是现在分词短语作后置定语，修饰前面的 animals。相当于一个定语从句 which/that live in and around the sea。
例如：
The boy standing there is my brother. 站在那儿的男孩是我弟弟。
standing there 修饰 the boy，可转换为 The boy who/that is standing there is my brother.

Did you know I can live up to 90 years That’s about as long as humans! When my life ends in the ocean, my body becomes a super important buffet for animals living in and around the sea. By helping so many animals survive, I keep the ocean happy and healthy. That’s why humans need to protect my whale family.

按照以下维度，完成改写后先自查。再和同伴交流，互相评价、提建议。
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!
One Possible Version:
1.Blue whales live in all oceans except the Arctic Ocean.蓝鲸生活在除北冰洋以外的所有海洋中。
辨析:except,except for,but与besides
except 除……之外(没有…)，着重强调在同类人或物中除去 一个或几个人或物,表示一种排除关系,有“减去”之意。
except for 除……之外，表示对整体主要部分的肯定和对局部的否定,起部分修正作用
but 除……之外，和except的用法基本相同,但着重强调整句的内容,习惯上用于no,nothing,anything等词之后
besides除……之外(还有…)，指在整体中加入一部分,表示一种累加关系,有“加上”之意

except We are all here except/but Tom.除汤姆之外,我们都在这里了。(不包括 Tom)
except for He is a good man except for his bad temper.
除了脾气有点儿差之外,他是一个好人。

2.This food lasts for over a year and it helps to create a lively and healthy ecosystem.这些食物能维持一年多，有助于创造一个生机勃勃、健康的生态系统。
