我们住在海底的一个圆屋顶下。

We lived under a dome at the bottom of the ocean.

图一：米开朗基罗设计的圣彼得大教堂圆屋顶。

Figure 1: The dome at St. Peter's Basilica, designed by Michelangelo.

那是一个“会飞的圆屋顶”，大约20英尺宽，在草丛上空盘旋。

It was a "flying dome", 20 feet wide, hovering above the grass.

复兴古罗马的形式，包括廊柱和圆拱，地道的拱顶以及圆屋顶。

There was a revival of ancient Roman forms, including the column and round arch, the tunnel vault, and the dome.

冰鸿淋就像浪端的小舟一样向上浮，在碳酸和冰淇淋共同作用下，像圆屋顶的乳白色大泡泡漫出杯顶。

The scoop of ice cream will rise like a boat on the tide and a reaction between the carbonation and ice cream will cause a dome of big creamy bubbles to rise over the top of the glass.
