When I was young，I was very proud.I liked to show off（炫耀） in front of others to earn their 1 .But after one 2 experience，I came to understand that it's important to be modest（谦虚）.
One day，my friend and I were riding our bikes in a park.My mother knew I had just learned how to ride for a short time， 3 she asked me to wear some safety equipment. "No，I won't wear 4 !" I said，pointing at my friend's elbows and knees， "She doesn't wear it，either!" "It's dangerous，" my friend said， "You need more practice." "I might have learned 5 than you，but I can ride even better!" I said loudly.She 6 her eyes and said， "Let's wait and see!"
I saw a path leading into some woods. "I'll race you!" I shouted.Then we rode towards the woods.7 ，the path wasn't as smooth as I thought.I kept bumping（颠簸） up and down，and then suddenly…bam!I fell off my bike.I 8 my elbows and knees bleeding. "Ha—ha!" My friend 9 and helped me up. "Be more careful next time，" she said.Tears ran down my face. "Sorry，" I said.
All in all，this experience made me realize that we must be 10 .A fall into a pit，a gain in my wit.
