放学后我在家里写作业，突然我听见有钥匙开锁的声音，我伸头一看，啊，原来是妈妈回来了。妈妈的脸上挂满了疲惫两个字，我连忙放下铅笔，三步并作两步走到饮水机旁，给妈妈倒了一杯水，递到妈妈的手上妈妈喝了一口水，摸了摸我的头说：“我的儿子长大了。”顿时喜悦之情洋溢在妈妈的脸上。。。。。。
After school, I was doing my homework at home. Suddenly I heard the sound of a key unlocking. I stretched out my head and saw that it was my mother who had come back. My mother's face was covered with two words of exhaustion. I quickly put down my pencil, walked to the water dispenser step by step, poured a glass of water for my mother, handed it to my mother's hand, and my mother took a sip of water, touched my head and said, "my son has grown up." All of a sudden, the joy filled my mother's face......
我以后要多为妈妈做一些力所能及的事情，让妈妈的脸上再多一些笑容。
I will do more for my mother in the future and make her smile more.
