having been done是完成被動(dòng)式、完成式、被動(dòng)式、被動(dòng)語(yǔ)態(tài)完成式、現(xiàn)在分詞完成時(shí)的被動(dòng)，強(qiáng)調(diào)時(shí)間先后；done可作形容詞和動(dòng)詞，含義為完畢、結(jié)束、做、行動(dòng)等，不強(qiáng)調(diào)時(shí)間先后。

having been done和done的區(qū)別是什么

兩者最基本的區(qū)別就在done不強(qiáng)調(diào)時(shí)間先后，而having been done則強(qiáng)調(diào)時(shí)間先后。

having been done首先是表被動(dòng)，另外它指的是此動(dòng)作發(fā)生在謂語(yǔ)動(dòng)詞的動(dòng)作之前。如：Having been used for many years, the bike needs repairing.(使用的動(dòng)作發(fā)生在修理之前，所以用到了having been done的形式)

而done只是表示被動(dòng)和完成，如：Used as a means of traffic in China, the bike is very useful (此句中自行車與使用之間存在被動(dòng)關(guān)系，所以直接使用了done的形式)又如：Told several times, he couldn't understand what I meant.(此句中的他與告訴之間的關(guān)系是被動(dòng)，而且是已經(jīng)被告訴過(guò)了，動(dòng)作已經(jīng)完成，所以直接使用done的形式了。)
