1.【语意表述】某人的不好的情绪安稳下来，镇静下来。

【句型模板】Somebody calms his nerves.

【指点迷津】calm是“使镇静”的意思，nerve是“神经紧张，焦躁，忧虑”的意思，calm one’s nerves的意思就是“使某人的神经紧张缓和下来，消除焦躁忧虑的情绪”。作为这个意思，它是可数名词。例如：
She doesn't know what nerves are. 她遇事从不着急烦恼。

(i.e. is never worried, upset, etc by events )

He has nerves of steel. 他沉得住气。

(i.e. a very calm temperament in times of stress, danger, etc.)

We'll have to treat him like a god for a month to calm his nerves.

【句型操练】It takes time to clam my nerves.

我的情绪缓和需要时间。

【句型出处】He'll be afraid this will change the way we think of him.

2.【语意表述】某人知道、发现某人的事情。

【句型模板】Somebody find something out about somebody.

【指点迷津】fin out是个固定短语，意思是“发现，发觉，弄清楚”。表示“知道了某人的事情”，用find something out about somebody。

【句型操练】I found the affair out about Mary and his boss.

我发现了玛丽和她的上司的艳事。

【句型出处】I shouldn't care what I found out about you, whatever it was.
