An Important Lesson

It was an early September day, cool and bright and just right for running, and I was in the first few miles of a 10 1/2 mile race over a course through steep, exhausting hills. Still, I felt rested and springy; despite the hills it was going to be a fine run.

• springy: returning quickly to the usual shape, after being pulled, pushed, crushed, etc. 有弹性的，有弹力的，轻快的，矫健的。
