If I had only one day to live, I would hang out with my sister. My sister is very important to me because we have made lots of sweet memories together. We are very close to each other.
On my last day, I would spend the whole day with my sister. We could watch anime and eat our favorite snacks together. We would even visit Japan. It's my favorite country in the world, so I would like to visit there again with my family.
One thing I have never done but always wanted to try is playing in the snow. I want to do this because it sounds like a super cool idea. I would make a snowman, have a snowball fight, and even build an igloo of my own. My sister and I would surely have a lot of fun.
At the end of the day, I would tell my sister, "We have made lots of sweet memories together. Thank you for everything." I would feel very satisfied because I've done all that I wanted to do. I can wave goodbye to the world with no regrets.

如果我只剩下一天可以活，我會和我妹妹一起度過。我的妹妹對我來說非常重要，因為我們一起創造了很多甜蜜的回憶。我們彼此非常親近。
在最後一天，我會和妹妹一起待上一整天。我們可以一起看動漫，吃我們最喜歡的零食。甚至我們還會一起去日本。那是我最喜歡的國家，我希望能和家人再去一次。
有一件事我從來沒做過但一直想嘗試，就是在雪地裡玩。我想做這件事，是因為聽起來超級好玩的。我會堆雪人、打雪仗，甚至還會自己搭一個冰屋。我和妹妹一定會玩得很開心。
一天結束時，我會對妹妹說："我們一起創造了很多甜蜜的回憶。謝謝你為我做的一切。"我會感到很滿足，因為我做了所有想做的事。我可以毫無遺憾地對世界揮揮手道別。
