完形填空

    One sunny day, I decided to go for a walk with my husband. I was wearing a special1 ring that day. It was my 20th birthday gift from my grandmother.

    As we were walking in the park, I just looked 2 at my hand and found the diamond on my ring was missing. I was really 3 so I went back to look for it. I knew how small the chances were of finding it, but I still wanted to give it a try.

    As I was fixing my eyes on the ground, I ran into an old gentleman 4.

    “What's the matter, love?” he asked nicely.

    “Sorry that I ran into you,” I said. “But I lost something important. I'm really nervous.”

    I explained about the missing diamond and showed him the5 in my ring.

    “That's not going to be easy to find it,” he said. “Tell you what, love, I take a walk here every day. I'll6 my eyes open for it.”

    I thanked him, expecting7. However, a few days later, my husband and I met the old man again in the park.

    “Guess what,” he said. “I found your diamond!”

    I couldn't believe what I saw when the gentleman handed the diamond back to me. Then my husband8him money for his help, but he refused.

    As the diamond is worth several thousand dollars, the old man could have easily kept the diamond 9sold it, but he did neither of these.

    Now thanks to this man, I always look at my ring and remind10 that there are still kind and generous souls out there. I'll spend more time trying to do something equally nice for other people.
