獨立主格結構的done和beingdone

This article deals with common social problems， with much attention being paid to problems of teenagers.

我們把這句還原一下得到如下：

This article deals with common social problems.

Much attention is being paid to problems of teenagers. 其中is being paid to是被動語態的現在進行式，其表達的動作性很強。上下兩個句子結合起來，形成帶伴隨狀語的複雜句。那麼，g done的形式被保留下來加強動作的描述。

而第二句：

He lay on his back with his teeth set and his eyes closed?

只是表示一種普通而穩定的狀態，正在發生的意味不強，故沒有加being。
