求翻译：今天爸爸妈妈都出去了，家里只剩下我和弟弟，我们完成了今天的作业后，一起看电视，过了很长时间还没来，我就到厨房想为他们做饭。他们来了，脸上露除了笑容，我也很高兴。是什么意思？

MOM and dad are out today, only my brother and I left home, after we have completed the job today, watch TV, after a long period of time has not come, I went to the kitchen to cook for them. They came, dew but a smile on my face, I am also very happy.
