     A lift is wonderful. It is really only a small room. Rooms usually stay in one place. Lifts travel up and

down all day long.

     Sometimes a worker stands in the lift. He or she operates it up and down. In modern lifts there is no

worker. The people walk in. They know what floor they want. They push a button and the lift goes to

that floor. It is all very fast and easy.

     Lifts are very important to us. Why? Think about a tall building. Maybe it has twenty floors. Maybe it

has fifty or more. Who can walk up all the stairs? Maybe people can climb them one time. Can someone

climb thirty floors to an office every day? Can small children walk up to their room on the twenty-fourth

floor? Can their mother and father carry food up all those stairs? Of course not.

      We can have high buildings because we have lifts. We could not have all the beautiful tall buildings in

the world without lifts. They are really wonderful.
