I was thirteen when I learnt a mistake could be changed into something else.

That spring, I was asked to ____1____ the backdrop (背景幕布) for the school play. Two days later, I finished a perfect blue sky with soft white clouds. I stood back, pleased with myself—____2____ my brush slipped (滑落). A long, ____3____ brown line cut straight across the sky like a scar (疤痕).

My heart dropped. There was no time to start again. I stood ____4____, looking at my failure, when my art teacher walked over. She didn’t say a word. ____5____, she picked up a brush and turned that brown line into the trunk (树干) of a tall tree. Then she added leaves, and two small birds resting among them.

What had been a scarred ____6____ suddenly became a landscape—peaceful, deep, and fantastic. The mistake saved the painting from being a (n) ____7____ one!

That moment stayed with me. I later learnt that some of the world’s best ____8____ began as accidents, like penicillin (青霉素) or the microwave. But the real ____9____ of a mistake is not just what it becomes, but what it does to you. It forces you to stop, to look again, and to try something you never ____10____.

Now, whenever I ____11____ a difficult or unpleasant situation—in a test, in a friendship, or in something I build — I try not to freeze. I ____12____ myself: This could be a bend (拐弯) in the road, not the end. It’s just a door you haven’t opened yet.
