without 的复合结构能再详细点吗？O(∩_∩)O谢谢~with结构的构成　　它是由介词with或without+复合结构构成，复合结构作介词with或without的复合宾语，复合宾语中第一部分宾语由名词或代词充当，第二部分补足语由形容词、副词、介词短语、动词不定式或分词充当，分词可以是现在分词，也可以是过去分词。With结构构成方式如下： with或without-名词/代词+形容词　　例句：He is used to sleeping with the windows open. with或without-名词/代词+副词　　例句：She left the room with all the lights on. with或without-名词/代词+介词短语　　例句：He walked into the dark street with a stick in his hand. with或without-名词/代词 +动词不定式　　例句：With so much work to do, I have no time for a holiday. with或without-名词/代词 +分词　　例句：We found the house easily with the little boy leading the way.(现在分词表示主动动作，即分词所表示的动作是由with后的宾语发出来的) 　　With all the things she needed bought, she went home happily.(过去分词表示被动，with后面的宾语与过去分词之间是被动关系) without+名词/代词+补语　　例句：Possibly this person died without anyone knowing where the coins were hidden. 　　He wondered if he could slide out of the lecture hall without anyone noticing (him). 　　with the winter is coming with+不定式和+分词的区别　　加不定式是指将要进行的动作,加分词是指主动或被动动作. 　　with +宾语（名词，代词）+名词 　　He died with his daughter a schoolgirl 　　他在他女儿是个小学生的时候死了复合结构是什么意思？O(∩_∩)O谢谢
