Gift from a stranger

    My local supermarket is always busy. The first parking space I found was convenient, but I'd noticed a woman in a blue car circling for a while.____ I was in a good mood, I let her have it. On the edge of the car park I backed into the next available spot—it was a tight fit.

    Pretty soon I'd made my way through the supermarket and was back in the fresh air. Feeling good, I____(empty) my purse change into the hands of a homeless man and helped a struggling woman reverse park（倒车）.

    Just as I approached my car, 1 saw the woman I'd let have my car space earlier. She was giving me ____ odd look—half puzzled, half intent (热切的). I smiled and wished her a pleasant day. As I squeezed back into my car, I spotted the same lady ____ (look) in at me. "Hello," she said, hesitantly. "This _____ sound crazy but I was on my way to drop some of my mother's things off at the charity bins.” You are just so much ____ her.” You helped those people, I noticed, and you seemed so happy.” She looked at me meaningfully and passed a box in through the window. “I think she would like you to have it.”____ (shock), I took it from her automatically. She smiled and walked away.

    After a pause, I opened the box. Inside was a beautiful gold necklace with a large grey pearl. It was ____ (nice) gift I'd ever received, and it was from a complete stranger. The necklace was around my neck, a warm reminder of human kindness.

想一想，议一议。
