第一个是不定式,用不定式的完成时表示发生在谓语动词之前.如i am sorry to keep waiting (很抱歉得让你等,表示“等”还未发生) 而i am sorry to have kept you waiting(让你等了这么久,表示等待发生了)
而第二个句子,是用谓语动词的时态(过去时)表示发生了.前一个是非谓语动词的时态.第二个不也是发生在谓语之前吗但是有yesterday ,所以明显过去时标志,再说谓语动词是现在时,i am sorry ,你只能用过去时。
sorry to have woken you up yesterday还有i am sorry that i woke you up yesterday
sorry to have woken you up yesterday还有i am sorry that i woke you up yesterday
为什么第一个用完成时态而 第二个用过去时态 求高手解答
