The most important life lesson Monica has learned from running is to run at her own speed.
Last year, Monica's school held a charity marathon(慈善马拉松) to 1 money for some poor students in need. It was so 2 that almost all students wanted to take part in it. So did Monica.
At the beginning of the marathon, all the other runners ran faster than her, which made Monica 3 . Though she tried her best to catch up with them, she still fell behind! She even wanted to 4 running, but she knew she couldn't! This was running for love!
Suddenly, she heard a loud 5 ,"Run at your own best speed!"She lifted her head and found it came from her father. "Run at my own best speed,"Monica thought for a while. Then she 6 running again. This time, she paid no attention to other 7 . Over time, Monica ran more easily and more 8 . After about two hours,Monica finally completed the marathon, and even won the second place!
What a(n) 9 result! Monica's father waited at the finishing line and gave 10 a big hug, and they laughed happily together. Other people's speed isn't the speed you should run at. Just run at your own speed!
