Dear John,
How are you? Let me tell you something about my trip. I went to Jinan last weekend. I went there by train last Saturday. I got to Jinan at about 10 o’clock in the morning. My aunt and uncle met me at the train station. And we took a taxi to the Daming Lake. We took a boat trip on the lake. Then we went to Baotu Spring Park. It was a hot and sunny day. We felt hungry and thirsty, then we sat under a tree and had our lunch. We had some bread, apples, hamburgers, milk and orange juice. I saw some fish in the water. We fed the fish some bread. Then more and more fish swam there and opened their mouths. It was very funny.
How about your weekend? Write to me soon!
Yours,
Peter
