潺潺的溪流，潇潇的北风，激昂的宣誓，世间万物都有着独特的声音，而那独特的声音却被我深深地印在脑中。

凌晨2点，一串急促的电话铃，打破了夜晚的寂静，妈妈立马起身揉了模糊的眼睛，接听了电话。听了电话内容，她立刻紧张了起来，迅速地收拾好东西，出发去了疫情的最一线。

早上，我像往常一样醒来，但没有看到妈妈，也没有觉得奇怪，因为妈妈平常就工作繁忙，经常不在家，可想到妈妈今天不上班，心中起了疑心。直到打开手机，听到妈妈的语音才知晓了一切：“儿子，我要去支援了，你要一个人在家了。加油，我和你一起努力。”那天，我心不在焉，一直想着这件事。

又一个静寂的晚上，我无意点开了妈妈的语音。那特别的声音又在我的耳边响起：“加油，我和你一起努力！”我反复咀嚼着这句话，深深地印在脑中，心中的斗志被点燃。就此，我发奋努力，想着妈妈在一线与可怕的病毒近身肉搏，而我只用和学习斗争，相比之下，学习是那么简单。

The gurgling stream, the sloppy north wind, the passionate oath, everything in the world has a unique voice, and that unique voice is deeply imprinted in my mind.

At 2 o'clock in the morning, a series of rapid phone rings broke the silence of the night. My mother immediately got up and rubbed her blurred eyes and answered the phone. After listening to the content of the phone call, she immediately became nervous, quickly packed her things, and set off to the front line of the epidemic.

In the morning, I woke up as usual, but I didn't see my mother, and I didn't find it strange, because my mother was usually busy with work and was often away from home, but when I thought that my mother didn't go to work today, I became suspicious. I didn't know everything until I turned on the phone and heard my mother's voice: "Son, I'm going to support, and you're going to be home alone. Come on, I'll work hard with you." That day, I was absent-minded and kept thinking about it. .

Another silent night, I accidentally turned on my mother's voice. That special voice sounded in my ears again: "Come on, I'll work hard with you!" I chewed this sentence repeatedly, and it was deeply imprinted in my mind, and the fighting spirit in my heart was ignited. At this point, I worked hard, thinking that my mother was on the front line fighting the terrible virus hand-to-hand, and I only had to fight with learning, which is so simple by comparison.
