Last Weekend,we had a picnic on the outskirts of our city with some friends of mine.We came there by bike in the morning.There is a grassplot and a stream runs throught it.We set a camp by the stream under some trees.At noon,we began to get ready for our picnic.We had brought a lot of food and bottles of mine water.We sang and danced on the grass while having our delicious meal.We had a wondeful time there.We hated to part with it（不忍得離去）in the late afternoon.
