Tears filled my eyes when I stood in our room. I was washing new jeans and a shirt of my 16-year- old stepson(继子), Brett. He drank a lot last night. The clothing was already dirty.
I was very tired. The clothes were just one thing. He had already kicked a large hole in his bedroom wall. Many windows were broken because of his breaking in to steal money. Brett came to live with us when he was 12 years old. During those four years I had dealt with Brett as patiently as possible, but inside I was feeling sad. Later, I cheered up again and continued parenting Brett. Still, Brett did not change his behavior.
When Brett was nearly 18, my husband and I decided to send Brett to a boarding school that had very good result with troubled teenagers.
At the graduation ceremony the graduates stood one by one to thank those who had helped them. Each graduate held a rose to give to the person who had meant the most to him or her.
Brett spoke lovingly to me, “You did so much. You were always there, no matter what
happened.You always showed me such love. And I want you to know that I love you for “it”.
Surprised, I stood as Brett placed the white rose in my hand and hugged me hard. At that moment I realized the truth-although I had been angry in my heart toward my stepson, Brett had seen only my actions.

，即v＝
，单位是m/s。初中还有很多这样定义的物理量，这种定义物理量的方法叫做比值定义法。我们在高中物理当中也有很多这样定义的物理量，如：把物体在单位时间内速度的变化量叫加速度（注：速度的变化量用△v表示，它等于前后两故速度之差；加速度用字母a表示，国际单位是m/s2）。由加速度的定义可知：
