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 fallen tree 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 his truck. For the next few minutes, he cut the tree into several parts and I carried them across the road and dropped them on the other side.
"You never know when you will need a chainsaw, " I joked. Then I waved goodbye and watched him drive off.
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.
