▲独立主格主要用作状语。但偶尔也用作其他成分。如下面两句中的独立主格则理解为这语（并可转化为定语从句）：
He had maybe a thousand tapes, all neatly labelled and catalogued. 
= He had maybe a thousand tapes, all of which were neatly labelled and catalogued.
他大约有1,000盒磁带，都整齐地贴着标签并分了类。
We produce our own hair-care products, all based on herbal recipes.
= We produce our own hair-care products, all of which are based on herbal recipes.
我们自己生产护发产品，全部采用草本配方。

▲又如，there be 的非谓语形式（there being与there to be）也可以视为一种独立主格（因为其中的there可视为逻辑上的主语或虚义主语），它可以用作表语或宾语等。如：
Your adviser’s experience is there to be tapped. 可以利用你的顾问的经验。
They planned on there being another meeting. 他们打算再开一次会议。
They asked for there to be another meeting. 他们要求再开一次会议。
I expect there to be a big response to our advertisement. 我预料我们的广告会有很大的反响。
