Translate the following text into Chinese. Write your translation on the ANSWER SHEET.
In the United State of America houses have changed as social customs changed. At first, American houses followed the patterns brought from Europe by the early immigrants, but, since timber was the most easily obtained material, boarded walls and shingle roofs largely replaced bricks and tiles. Lately, different regions have evolved their own methods of house building to suit local conditions; for instance, a low rambling house with widely spreading eaves, is typical of the Pacific coast. In addition, the plan of the house has begun to change as the American way of life has diverged more and more from the European. Houses are less formal, and rooms merge one into the other, providing more space for general family life and fewer rooms for special purposes.
