completely 和 absolutely 和 perfectly 有什么区别？如果难以说明的话，请教我一下例句。

"Completely" means fullest of something. Like "I am completely full", "the piano was completely broken" or "he was completely tired." "Absolutely" is the same, but it is used less than "completely". But "absolutely" is natural too. "Do you like coffee? Absolutely." Sometimes we use it as a response to "thank you". "Thank you for helping me. Absolutely." It's like when you respond "пожалуйста" when you hear "спасибо". But it is much more common to respond "you are welcome" instead of "absolutely". Perfect can mean something is the best possible or means something has no errors at all. Like "this piano's time is perfect!" Or "only one perfect man existed".
