题目内容：
hese things didn.t happen to our family，that.s what my uncle said．It seemed like the world turned upside down； just last
week my grandmother had passed away．I felt like I couldn.t
get my feet on solid ground．
That.s when my sister，Madi，came down the stairs with her long
brown hair freshly washed．She sat next to me and smiled．
Despite what was happening，everything would work out，her
smile seemed to say．
"Mom，do you think I could get my hair cut tomorrow？"Madi asked．
"Sure，"Mom said，starting to wash the dishes
"I want to donate it to Locks of Love"Madi smiled．My mom stopped washing and turned to look at her．
"Are you sure？"I noticed that Mom was holding back tears．This was a sacrifice（牺牲） for Madi．Her long hair was animportant part of her．
"Yeah，it.s just hair．Eventually it will grow back．"She said．
"All right，"Mom said quietly，smiling again．
Madi gave up a part of herself for a while．She let a piece of herself go to someone else，someone she didn.t know．That day
she became my hero too．
