The billowing smoke coming out of the engines.

汹涌的浓烟从引擎涌出来

Below is the green water billowing on.

下面是绿色的水向前翻腾。

The wind blew hard and the sea was billowing.

风吹得很大，海上巨浪翻滚着。

There was a horrible, swelling, billowing silence.

教室里一片可怕的、酝酿着惊涛骇浪的沉默。

The train appeared, smoke billowing from the funnel of the engine.

火车开来了，车头的烟囱里冒出滚滚浓烟。

What says summer more clearly than white curtains billowing in a breeze?

有什么比飘荡在微风中的白窗帘更有夏天味儿？
