having been done和done的区别

having been done是完成被动式、完成式、被动式、被动语态完成式、现在分词完成时的被动，强调时间先后；done可作形容词和动词，含义为完毕、结束、做、行动等，不强调时间先后。

having been done和done的区别是什么

两者最基本的区别就在done不强调时间先后，而having been done则强调时间先后。

having been done首先是表被动，另外它指的是此动作发生在谓语动词的动作之前。如：Having been used for many years, the bike needs repairing.(使用的动作发生在修理之前，所以用到了having been done的形式)

而done只是表示被动和完成，如：Used as a means of traffic in China, the bike is very useful (此句中自行车与使用之间存在被动关系，所以直接使用了done的形式)又如：Told several times, he couldn't understand what I meant.(此句中的他与告诉之间的关系是被动，而且是已经被告诉过了，动作已经完成，所以直接使用done的形式了。)
