While(当……时候) waiting for the bus, I put my white stick into my bag. A little girl came up and asked me, “Would you please help me cross the street? I am afraid of cars.” “Sure,” I said, “Let’s walk to where the white line are painted across the street.” The little girl said “ OK”. At the crossing, I said, “now, look carefully. When you see no cars are coming, tell me.” In this way we crossed the street.
Safely on the other side, the little girl thanked me and ran away. I waited until the sound of her steps died away(消失) before taking out my stick to make the return crossing.
1．One day, the man wanted to cross the road.
