    I live in a nice new building in Beijing. It is very tall. It has eighteen floors. There are about eighty families in the building. That is to say (也就是说), about two hundred and forty people live in the building.

    My home is on the twelfth floor. We have two bedrooms and a living room. They are big and clean. There are a lot of big trees and beautiful flowers around our building.
