Hello, I’m Vladislav. For my summer holidays, I usually stay in a country house near Moscow.
Last summer, my dad’s brother gave me a present — a blue bike. At that time I couldn’t ride it very well.
One day I got into an accident. But don’t worry, everything was OK, just some “little” injuries.
That day, I tried to ride my bike and suddenly it began to move very fast. I couldn’t stop the bike. So I fell into a ditch (沟) full of dirty water. When I thought I had had enough bad luck, a girl walked by. She saw the bike and me. I quickly stood up.
“Are you fishing here?” she asked.
“Yes,” I answered. Then I said, “I’m making fish soup for dinner. Would you like to come?” To my surprise, she agreed.
After that we became friends. Now, we often send each other e-mails. She knows that I’m studying in China and she asks me questions about Chinese culture. I tell her my stories of China, and she says she wants to visit China, too. She even plans to study Chinese.
This is how, with the help of my bike, China got one more Russian friend.
根据短文内容,回答下列问题。
1.Who sent Vladislav a bike last summer?
