It is made of light steel.

它由轻钢制成。

Without any suggestion of a ledge or a tabletop, indispensable for conventional still-life, the opaque foreground is painted in light steel gray.

没有表明这是壁架还是桌面，这对于传统静物画不可或缺，不透明的前景被漆成轻钢灰色。

The light steel windmills tremble throughout their frames and tug at their moorings, as they vibrate in the wind that often blows from one week's end to another across that high, active, resolute stretch of country.

轻钢风车的整个框架都在颤抖，并拉动着它们的系泊设备，因为它们在风中振动，风经常从一周结束吹到另一个周末，穿过那片高耸、活跃、坚决的国家。
