There wasn't a breath of wind.

一点风也没有。

It was too hot without a breath of wind.

天气很炎热，连一丝风也没有。

Not even a breath of wind stirred the pine branches.

一丝风也没有，松树枝条纹丝不动。

All of a sudden, the mountains seem strangely near. There isn't a breath of wind, yet dense clouds pile up in the sky.

后来群山一下子看上去今得令人毛骨悚然，一丝风也没有，然而乌云却在翻滚着。
