Last weekend we went mountain-climbing．Even the heavy rain in the morning could

not prevent us go．Setting off very early, we went along an extreme narrow road, all in

high spirits．On every side of the road were green fields and some farm house．We could

hear the sound of the rain and our footsteps mixing with our laughter．At noon we

reached top of the mountain．That surprised us most was the beauty of the scenes

there．After having a short rest and sharing with the food we had brought, we started

going down．It rained even harder．We are wet to the skin, and we still sang and

laughed happily．
