听力原文： Frank Wright did not call himself an artist. He called himself an architect. But

the buildings he designed were works of art. He looked at the ugly square buildings around him, and he did not like what he saw. He wondered why people built ugly homes, when they could have beautiful ones.

Frank Wright lived from 1869 to 1959. When he was young, there were no courses in architecture, so he went to work in an architect's office in order to learn bow to design buildings. Soon he was designing buildings that were beautiful.

He also wanted to make his buildings fit into the land around them. One of the houses he designed is on top of a high hill. Other people built tall square houses on hills, but Wright did not want to lose the beauty of the hill. He built the house low and wide. Now other architects know how to design buildings to fit into the land and the environment because Frank Wright showed them how to do it.
