过去完成时是指在过去的某个时间点以前已经发生完的动作,例,Mary
had
finished
her
homework
before
he
father
came
back
home.
而现在完成时是指在现在时的状况下已经完成的动作,并对现在产生一定的影响,例,Mary
has
finished
her
homework
and
her
father
agrees
to
let
he
watch
TV.希望对你有帮助~

过去的过去是过去进行时,对现在没有影响;现在进行时是以前发生的对现在有一定影响。比如一个过去完成式,It's
nine
o'clock
now,I
had
finished
my
homework
by
eight
o'clock。八点是九点之前的一个时间段,所以是过去进行时
