1 . One Monday morning, while the children were enjoying “free play”, I stepped to the doorway of the classroom to take a break. Suddenly, I _________ a movement of the heavy wooden door. This was the very door I _________ guided the children through to ensure their safety from the bitter cold. I felt a chill (寒意) go through my body.

My legs carried me to that door, and I pushed it open. It was one of my kindergarteners who I thought was _________ that day. He had been dropped off at school late and was _________ to open the door.

He must have been waiting there for quite a while! Without a word, I rushed him to the hospital. He was treated for frostbite on his hands. He’d need time to _________ , and wouldn’t come for class the next day, I thought.

The next morning, one of the first to _________ was my little frostbitten boy. Not only did he run in with energy, but his _________ could be heard as loud as ever! I gave him a warm hug and told him how _________ I was to see him. His words have stayed with me all these years, “I knew you would open the door.”

That cold Monday morning, he waited a long, long while for adults to _________. To a child, every minute feels like forever. He didn’t attempt to walk back home; he waited and trusted. This five-year-old taught me a powerful lesson in __________ .
