Yesterday li Ming and I took a part in an outdoor camping activity, We got up as earlier as possible but put on strong and comfortable shoes. Then they headed for a hill with some food in the bags. When reaching the top, we saw a direction mark, that told us the position of the campsite. Down the hill. we come to a river but didnt know how to cross it. Suddenly I came up an idea. We ut our bags on a board and swam in the water push the board. After getting to the other ba"ks, we alkerl for half an hour unless we arrived at the destination. We spent the night there
