AMPHITHEATER

圆形剧场

---

An amphitheater is an outdoor man-made structure or geological formation used for viewing lectures, concerts, or theatrical performances. The stage or focal point is at the lowest level, and sloped seating ascends in straight or curved rows.

圆形剧场是用于观看讲座，音乐会或戏剧表演的户外人造结构或地质构造。舞台或焦点处于最底平面，倾斜的座位呈直线或曲线上升。

The ancient Roman amphitheater was a public building, circular or elliptical in shape, that was used for spectator sports, games, and displays. In contrast, the ancient Greek amphitheater was a Classical theater, semicircular in shape, that was used for theatrical performances.

古罗马圆形剧场是一种圆形或椭圆形的公共建筑，用于观看体育比赛和展览。相比之下，古希腊的圆形剧场是一个古典剧场，呈半圆形，用于戏剧表演。

A natural amphitheater is a bowl-like configuration in a mountainside, rock formation, or other topographical formation, which can be acoustically ideal for musical an theatrical performances. 

天然的圆形剧场是山坡上的一个碗形构造，由岩石或其他地质构造构成，这在声学上是音乐和戏剧表演的理想选择。

Sites with variable topography  may lend themselves to the making of an amphitheater as an outdoor room, gathering place, or sports venue. Too often the existing site conditions are ignored and the ground leveled to make way for a building that has little or no connection to its environmental context.

地形多变的场地可以用作露天剧场、聚会场所或运动场所。很多时候，现有的场地条件被忽视，为了给与环境很少或者毫无联系的建筑让路，地面被夷为平地。
