sorry,i fell asleep with the computer on,中的ON在句中作什么成份,我不是很明白

on在这里是副词"开着",这里是with的复合结构
with +名词(代词)+现在分词/过去分词/形容词/副词/不定式/介词短语
对不起,电脑开着我睡着勒
再问： 老师,你能举几个例子,给我看吗,with +名词+现在分词,,,,,with +名词+形容词 ...,with +名词+不定式.
再答： with the window closed(closed为形容词) with the light on副词 with a book in her hand介词短语 with a cat lying in her arms现在分词 with the problem solved过去分词 with the new term to begin不定式
再问： thank you very much
