英语高考专题复习讲与练----独立主格结构常见类型及其用法 独立主格结构是由一个相当于主语的名词或代词加上非谓语动词、形容词（副）词、或介词短语构成的一种独立成分。该结构不是句子，也不是从句，所以它内部的动词不能考虑其时态、人称和数的变化，它与其主句之间既不能通过并列连词连接也不能有从句引导词引导，常用逗号与其主句隔开。独立主格结构在很多情况下可以转化为相应的状语从句或其他状语形式，但很多时候不能转化为分词形式，因为它内部动词的逻辑主语与主句主语不一致。在做这类题目时一定要小心判断，不能粗心大意。一、独立主格结构的构成形式1、逻辑主语+V-ing这种构成形式内部的逻辑主语是分词的动作执行者，分词表示的动作不是整句主语发出的动作，而是其逻辑主语发出的动作。如：1. __________no bus, we had to walk home. A. There being B. Being C. Having been D. There was2. _______no bus, we had to walk home. A. As there being B. As there was C. Being D. There was3. _______Sunday, the library doesnt open. A. Being B. There being C. It being D. Having been4. ______Sunday, the library doesnt open. A. As it being B. Being C. It is D. As it is2、逻辑主语+V-ed该构成形式内部的逻辑主语是分词的动作承受者。如：1. _________, the train started. A.
