下面是prep2-110关于的注释： GMAT 当中常出现的独立主格结构只有一种，即 with 复合结构。它的构成是：“with＋宾语＋宾语补足语”。宾语由代词、名词、名词词组充当，宾补由分词、不定式、形容词、副词、介词短语、名词等充当。 E.g.: He used to sleep, with the door open. 他过去常开着门睡觉。（形容词） E.g.: With a boy leading the way，they started towards the village. （现在分词） E.g.: With the work done，he went home. （过去分词） E.g.: With you to help us，we will finish the task in time. （不定式）
