What do we do when we go camping? First, we think of a plan. We take food, clothes, a knife, and things for cooking and eating. We take things to keep us away from insects(昆虫) and the sun. Then we put everything into the car and we drive to the woods. We look for a place for campers(露营者) and we look for a good place for our tent(帐篷). The place should have a lot of air. This will keep some insects away. High land with water on both sides of it is good. Then we put up our tent. We put everything into the tent, and we are ready for fun. We can swim in the lake, walk in the woods, climb a mountain, row a boat, or go fishing. In the evening we come back to the tent, we build a big fire because it can keep the insects away. We sit around the fire and talk. We may tell interesting stories or we may sing songs. At night we lie down on the grass. We can look up at the stars. It is a busy day, so we try to go to sleep early. Everything is dark. Everything is quiet. We hope we won’t hear music from the radio in the next tent. We hope it won’t rain.
