a cool place to keep the boat - we have near some famous museums and a good library, and the view is great. The only problem is the weather. When it's windy, the boat goes up and down! Also we need to paint Marianne every year. In fact my dad and his friend are painting the houseboat now. When visitors come here, they walk into our living room first. They think it's great because it's really comfortable with a big TV, a sofa and modern painting. The kitchen is my favourite room. My mum is making dinner there now. We're going to eat in our garden, on the roof. 1. Read the text again and choose the best title. A. Living in London. B. An unusual home. C. The advantages of having a boat. 2. Answer the questions. Write complete sentences. 41. How many rooms has the houseboat got? What is Rory growing on the roof of the boat? How old is the houseboat? 2. 3. 4. What is the problem in the boat? 5. What are Rory's dad and his friend doing now? 6. What is Rory's mum doing now? /1/point /6/ points
