Charlie and his family don't always live in their house. Sometimes they live in a houseboat. There are 4 rooms in the bottom of the boat. One of them is his parents' bedroom. Another one is his bedroom. Then there is a kitchen and a bathroom. Charlie's bedroom is small, but he likes it very much. It has a small window. He doesn't open it because it's under the water. When the boat is in the water, Charlie can look out of his window and see many fish under the water. Once he saw an old car under the water. He thought it was funny to see the fish swim through the car windows.

    In the school year, Charlie's family keep their boat on the bank (岸) of the lake. In summer Charlie and his family often take their boat out to the middle of the lake. They stay on the lake for a few weeks. Then they go fishing for their food. Charlie's mother grows vegetables in pots on the boat, so they also have vegetables to eat. When it is very hot, they jump into the water and go swimming. Charlie thinks a houseboat is the best place to live in.
