1.這句話是對(duì)的.
2.have been 是be 的現(xiàn)在完成時(shí)態(tài)；
have done 是do 的現(xiàn)在完成時(shí)態(tài)；
have been done 是do 的現(xiàn)在完成時(shí)態(tài)的被動(dòng)語態(tài)形式.
3.I have been here for a long time.
其中的have been here 還原其實(shí)就是be here,只不過用了完成時(shí).也就是說,當(dāng)一般現(xiàn)在時(shí)用be 的時(shí)候,完成時(shí)就用have been.而be 常與形容詞、名詞、介詞短語等連用.如:
I have been in this city for a long time.
He has been a college student for three years.
4.have done 其實(shí)是所有完成時(shí)態(tài)的一個(gè)公式.
5.have been done 是被動(dòng)語態(tài)：.已經(jīng)被做了
He has been sent to the hospital.他已經(jīng)被送到醫(yī)院.
The classroom has been cleaned.
