爱的绝对值
句意为:我很抱歉让你等待很长时间,而keeping是修饰前面的sorry的,for keeping表示保持自己一直的歉意(别人等我很久)的意思。也可以不用keeping,用其他的词,
I am terribly sorry to keep you waiting for a long time.
I'm sorry to keep you waiting for such a long time.
I am sorry to have kept you waiting for a long time
I'm awfully sorry to have kept you waiting for a long time
都可以的
