What will the home of the future look like? A team of architects in Hong Kong say that city homes will be tiny, as populations continue to grow and space becomes more expensive.           They have designed “spaceflats” with just 30 square metres in size as the houses in the following years. These flats have several small rooms; a  living room, a bathroom and a bedroom, but everything is carefully planned to make good use of the limited space.           The living room is the main room of the flat. It can be used as an office, a kitchen or even a second bedroom. T16．④地的主要人种是（　　）A．混血种人B．黑种人C．白种人D．黄种人
