Last Saturday the students of our class made a bike trip to a small town by the Taihu Lake. We set off earlier in the morning. After getting to the town, we visit some places of interest. At noon, we had picnic near the town.  Everybody was attracted by the beautifully scenery and we took a lot of picture there. In the afternoon, some of us went fishing, some rowed boats on the water, but others flew kites. We both had a wonderful time! It was a pleasant trip for them, during which the boys were offered the girls a lot of help. We have learned to help, understand and sharing with others. In a word, we have got quite a lot from it.
