Yesterday my classmates and I went to on a picnic。 According to our plan we would climb the West Mountain。
Early in the morning all of us gathered at the gate of our school， we started of at seven， soon it began to have a little rain。 We kept on riding for an hour till we reached the foot of the mountain。
The little rain stopped then。 We began to climb。 Soon we reached the top of the mountain。 How beautiful it was when we looked at the view from the top。 We ran。 sang， jump， played chess， and had the pictures taken on the top of the mountain。 and had lunch on the rocks。 How happy we were!
After the lunch we went down the mountain。 We got home at four， all of us almost gave out。
