When I was seven years old my mom was diagnosed (诊断) with cancer. The doctors told us my mom
might be saved with surgery (手术). But it could also kill her. She chose to have it.
The day before the surgery I was off school, and my mom planned the best day of my life, everything I
loved at seven and everything that would put a smile on my face. The day began with her waking me up
saying, "Kate, I have a surprise for you. Come and see." The surprise was a doll I had wanted for the longest
time. Throughout the day, she told me everything that she thought I would need to know to grow up and be
a good person; she told me to be the best I could be and that I would always make her proud. We had a picnic
in the park, and it was so cold that we moved to the car. The day was filled with laughter. For the first time
in a long time I could see she was really happy. I would never forget her smile, or the way her eyes shone as
if we were the same age. It was the best day of my life, and I will never forget the conversations we shared.
My mother managed to live through the surgery. Now when I look back, I realize that the best day of my
life could be her last and this could be the last day I would remember with her, the last one we shared. I also
understand how unselfish a mother is.

当我七岁时,我的母亲确诊患有癌症.医生告诉我们动手术可能会救母亲.但是也有可能会失去生命,她选择了做手术.
做手术的前一天我没有去上学,母亲为我准备了生命中最美好的一天,带给了我七岁时喜欢的一切和能让我开心的东西.这一天从她把我叫醒说：“Kate,我有惊喜给你,快来看.”原来是一个我一直想要的玩具娃娃.这一天,她告诉我她认为我成长中需要了解的每件事,并且她告诉我要做个好人.她告诉我要做得最好,让我永远让她感动自豪.我们在公园野餐,因为太冷,我们回到了车里.那一天充满了欢笑,很长时间以来,我第一次感觉到她是如此的开心.我将永远不会忘记她的笑容,以及她眼睛闪烁的样子就像我们是同龄人.那是我生命中最美好的一天,我永远不会忘记我们一起谈过的话.
母亲成功地度过了手术,现在,回想起来,我才意识到最美好的那一天可能是她的最后一天,可能是我对她的最后记忆,可能是我们一起度过的最后一天.我也懂得了一位母亲是多么的无私.
