I'm sorry to keep you waiting.这是不是一个复合句?是什么复合句?这里的不定式to keep在句子中作什么语?

这不是一个复合句,不定式做原因状语,类似于I'm glad to meet you.动词不定式不是句子,而且有时在改同义句的改为简单句时就可以用不定式代替从句,比如l can tell you how you can get to the bank=l can tell you how to get to the bank.
再问：不是复合句，那是什么句子呢？主系表？
再答：简单句啊，l是主语，am是谓语，sorry是表语，不定式是原因状语。
再答：简单句啊，l是主语，am是谓语，sorry是表语，不定式是原因状语。
