But I could never understand her habit of cheering while we were walking in the race.
We walked together all over the town and entered half-marathons（半马拉松）, 26 miles.   
I carried it to the starting line along. It had twenty-six cheering ideas, one for each mile. But I wasn’t really planning to slow myself down with all those ideas. I had to keep her list because I didn’t want to hurt Tina’s feelings.
  I looked at Tina’s cheering list when I checked my watch. At the top of the list was only one word: “Yourself.” I thought it did give me a good start to the race. While I was at it, I took the chance to thank her for the strength the list brought to me. By the time I finished the second mile, my parents were cheering me on by the side of the road. It just so happened that “family” was the next on Tina’s cheering list. At that moment, I had plenty of things to be thankful for.
  But by the time I was close to the final mile, I was nearly out of breath. I didn’t know if I could make it another mile. Then I looked at the final idea on Tina’s list in my hand: “You can make it.”
   I had thought the cheering list would slow me down. Instead it carried me to cross the finishing line.

A. She gave me a cheering list to “talk” to me. B. I finished the marathon in less than six hours. C. Tina was the best speed-walker in our school. D. I walked the first mile of the race in 12 minutes. E. The next mile flew by, then the next and the next, each with a cheering idea.
