One day, Bob and Tim wanted to play with water. When they got to a river, they saw a lot of people (swim) in it. Some people had great fun (play) in the water. Bob asked, "What are they doing in the river?" Tim said, "They (catch) fish." He told Bob to stay on the bank, then he jumped into the water. About an hour later, Tim (swim) back to the bank with a fish in his hand. Bob was very happy. He found a bottle and put the fish into it. Bob said happily, "I (not see）such a lovely fish before."
