1.having been done即所謂的過(guò)去分詞的完成形式,它不能做（后置）定語(yǔ),但是可以做狀語(yǔ).
如：Having been admitted into Tsinghua University,he decided to treat himself to a big dinner with his whole family.
（已經(jīng)）被清華大學(xué)錄取之后,他決定和家人舉行大宴以犒勞自己.
2.如果要用表示已經(jīng)被完成的動(dòng)作的非謂語(yǔ)動(dòng)詞來(lái)做后置定語(yǔ)的話,只需要直接使用done（過(guò)去分詞）即可.
如：Did you attend the meeting held yesterday?
你參加了昨天舉行的會(huì)議了嗎?
