The mountains where I live are full of curvy (弯曲的) and dangerous roads. I was driving down one of those roads last spring. Days of rain made the ground slippery to drive on.
As I turned around a curve, I saw a tree that had fallen across the road. It blocked my way. I hit the brakes (刹车) and slowly drove around it. Then I stopped. I knew it was only a matter of time before someone driving faster than I was would run into that tree.
I got out of my car and tried to pull the tree into the ditch (沟)，but it was too big and heavy to move. I didn't know what to do. But 30 seconds later, a white truck appeared and pulled over.
Out stepped a young man. "You need a chainsaw (电锯)？" he asked. I said, "Yes!" He pulled one out of the back of his truck. For the next few minutes, he cut the tree into several parts while I carried them across the road and dropped them on the other side. "You never know when you will need a chainsaw," I joked while my new friend smiled and put his chainsaw back in the truck. I waved goodbye and watched him drive of before heading back to my own car.
In this life, you never know when you will need a chainsaw. You do know, however, when you will need a kind and loving heart.
