托福TPO/【学术讲座】#56听力原文What is the main topic of the talk?【新东方在线】

Listen to a talk in an architecture class.

女：津巴布韦哈拉雷的东门中心是一座集零售空间和办公室于一体的混合建筑综合体。

W: The Eastgate Center in Harare, Zimbabwe, is a mixing complex combining retail spaces and offices.

当建筑师米克·皮尔斯在20世纪90年代初被要求设计这座建筑时，他面临着一个巨大的挑战。

When the architect Mick Pierce was asked to design the building in the early 1990s, he faced a big challenge.

如何在没有传统空调的情况下，让所有商店和办公室保持凉爽，并且是在经济危机期间做到这一点。

How to keep all its shops and offices cool without traditional air conditioning and do it during an economic crisis.

能源成本高昂，而且进口先进的空调设备是不可能的。

Energy costs were high, and importing advanced air conditioners was impossible.

为了解决这个难题，皮尔斯将目光投向了白蚁丘。

To solve this dilemma Pierce looked to termite mounds.

Termites are insects that live in large colonies.

它们在非洲稀树草原的地面上建造巨大的土丘。

They build big mounds on the ground throughout the African savannah.

这些土丘是令人惊叹的结构，高出地面约3米，并向地下延伸1到3米。

The mounds are amazing structures, summarizing 3 m above ground and extend another one to 3 m below the ground.

地下腔室通过迷宫般的隧道网络与地上的烟囱相连，整个系统就像自然的气候控制系统一样运作。

The underground chambers connect to the above-ground chimneys through a maze of tunnels, and this entire system works like natural climate control.

暖空气上升并从顶部排出，而较冷的空气则从下方流入。

Warm air rises and escapes through the top, while cooler air flows in from below.

由土壤和黏土构成的厚墙在白天吸收热量，并在夜间释放出来。

The thick walls of soil and clay absorb heat during the day and release it at night.

白蚁通过打开和关闭通风口、添加或移除土壤来扩大或封堵通道，从而对气流进行微调。

Termites fine-tune airflow by opening and closing vents, adding or removing soil to enlarge or seal passages.

在炎热的日子里，它们会打开更多通风口来降温。

On hot days, they open more vents for cooling.

到了晚上，它们会关闭通风口以保持温暖。

东门中心的墙体由混凝土和砖块等厚实材料制成，整个建筑内还布置了管道系统和可调节百叶窗，以模仿白蚁丘的那些通风口。

The Eastgate Center's walls are made from thick materials like concrete and brick, and there's a system of ducts and adjustable louvers throughout the building to mimic those vents.

其结果是，这座建筑比传统同类建筑消耗的能源少得多。

The result, a building that uses far less energy than its conventional counterparts.

What is the Eastgate Centre built to house?

What was the architect's main challenge when designing the Eastgate Centre?

What does the speaker imply about vents in the termite mounds?

Listen to a talk in an architecture class. W: The Eastgate Center in Harare, Zimbabwe, is a mixing complex combining retail spaces and offices. When the architect Mick Pierce was asked to design the building in the early 1990s, he faced a big challenge. How to keep all its shops and offices cool without traditional air conditioning and do it during an economic crisis. Energy costs were high, and importing advanced air conditioners was impossible.

Termites fine tune airflow by opening and closing vents, adding or removing soil to enlarge or seal passages. On hot days, they open more vents for cooling. At night, they close them to keep warm. Thin Pierce borrowed these ideas.
