今天是母亲节，我想给妈妈一个特别的礼物。在我心里，妈妈是世界上最伟大的人，她对我无私的爱和支持让我感到温暖和安慰。

我决定给妈妈发一个短信，用英文表达我的感激和爱意。虽然我的英语不是很好，但我相信妈妈会感受到我的真诚和用心。

"Dear Mom,

Happy Mother's Day! Thank you for always being there for me, through the ups and downs, and for giving me your unconditional love and support. You are my role model and my inspiration.

I am so grateful to have you as my mother, and I hope this message conveys how much I love and appreciate you. Thank you for everything you do, and for being the best mom in the world.

Love always,

(Your name)"

我知道这条短信不能代表我所有的感激和爱意，但我希望妈妈可以从中感受到我的真诚和心意。我相信这个简单的举动，会让妈妈感到开心和幸福。
