Today I want to tell you about my dream house. I will live in a hi-tech house.It might be in the city. It will be surrounded by a full rose garden. There will be swimming pool in front. In the house, there will be ten rooms: 3 bedrooms, 3 bathrooms, a kitchen, a diningroom, a livingroom and a library room. My dream house will have solar energy and wind energy. There will be some robots in the house. There will help me do the housework and feed the dogs. And I might have a smart TV in the house. It help me suft the Internet and I can talk with you in other countries. That is my dream house
