2。
have
been
是be

have

have
been
done
是do

3.
i
have
been
here
for
a
long
time.
其中的have
been
here
还原其实就是be
here，只不过用了完成时。也就是说，当一般现在时用be
的时候，完成时就用have
been。而be
常与形容词、名词、介词短语等连用。如:
i
have
been
in
this
city
for
a
long
time.
he
has
been
a
college
student
for
three
years.
4.
have
done
其实是所有完成时态的一个公式。
5.
have
been
done
是被动语态：....已经被做了
he
has
been
sent
to
the
hospital.
他已经被送到医院。
the
classroom
has
been
cleaned.
