用作缘由状语（名词+不定式）
An important lecture to be given tomorrow , the professor has to stay up late into the night. 由于明天要发表一个要紧的演讲，教授不能不熬夜到非常晚。
用作随着状语（名词+过去分词；改为并列句）

表示补充说明（名词+形容词）
A hunter came in, his face red with cold . 一个猎人走了进去，他的脸冻得通红。

备注：独立主格结构表示时间、条件或缘由时，等于一个状语从句，通常放在句首，表示缘由时还可放在句末；表随着情况或补充说明时，等于一个并列句，一般放于句末。
