[单项选择]Architecture
Architecture is to building as literature is to the printed word. ’’The best buildings ate often so well constructed that they outlast their original use. They then survive not only as beautiful objects, but as documents of the history of cultures. These achievements are never wholly the work of individuals. Architecture is a social art.
The renaissance brought about an entirely new age, not only in philosophy and literature but in the visual arts as well. In architecture, the principles and styles of ancient Greece and Rome were brought back to life and reinterpreted. They remain dominant until the 20th century.
Many kinds of stone are used as building materials. Stone and marble were chosen for important monuments because they are not burnable and Can be expected to endure. Stone architecture was often blended with stone sculpture. The use of stone has declined, however, because a number of other materials ate more adaptable to industrial use.
