Composition
Today we visited the Hongxing Farm. In the early morning, we started from our school.
When arriving, we were warmly welcomed by the farmers there. The?header of the farm led us to the fields where we saw all kinds of crops growing well and we all felt very excited. In the middle of the day, we had an picnic lunch there and we all enjoyed it very much. After that, we sang and danced to our hearts’ content. Some of us even played chess and told interesting stories.
In the afternoon, we left the farm. I’ll never forget the memorable day!
