应该是： An unual experienceLast week, I came across a stray dog when I was taking a walk in my neighborhood. It was a cold day, and there was nobody around. I stopped and he looked at me helplessly. “What a poor dog!” I thought. Then I decided to bring him home. When we got back home, I gave him some food and drinks and played with him, but it seemed that he was a little sad. I knew he was missing his owner. What could I do? I came up with an idea. Then I put up a ‘Dog-Found-Notice" at the gate of our neighborhood with the help of Dad. A few days later, the owner of the dog came to my house. I was very happy to see the little dog go home with his owner, and I feel proud that I was able to give others a helping hand. What an unusua experience !
