例如：The boy being unhappy, I gave him a candy. = As the boy was unhappy, I gave him a candy.There being no buses, I had to walk home. = As there were no buses, I had to walk home.It raining tomorrow, we’ll have to put off the sports meet.= If it rains tomorrow, we’ll have to put off the sports meet.I waiting for the bus, a stone hit me on the head.= While I was waiting for the bus, a stone hit me on the head.独立主格构成有两种形式：一种是在名词或代词(人称代词时用主格形式)后直接加名词、形容词、副词、介词短语、现在分词、过去分词、不定式等；另一种是用with + 名词或代词(人称代词时用宾格) + 名词、形容词、副词、介词短语、现在分词、过去分词、不定式等。
一般来说表示“具有、携带着”等意思时，with加复合宾语结构较常用。
例如：It is so wet there that the trees are extremely tall, some measuring over 90 metres.那儿的湿度很大，所以树都长得特别高，一些高达90多米。
