什么是过去分词？？？和过去式有什么不同？？？什么时候要用过去分词？？？？ 回答要通俗一点。

Question

如题所述

Answer 1

一、过去时仅仅用来指过去的情况状态，只是相对于现在。e.g:她两年前是一名老师。she
was
a
teacher
two
years
ago.
过去分词通常在两种情况中出现：1、被动的过去式
e.g:“苹果被我被吃掉”（强调动作的已经发生）the
apple
was
eaten
by
me
2、表已经完成了的动作。包括其一现在完成时（相对于现在已经发生了）e.g:“我完成作业了”（对于现在我已经完成了）i
have
finished
my
homework
其二过去完成时（相当于过去已经完成）e.g:“昨天姑妈来的时候我已经完成作业了”i
had
already
finished
my
homework
when
aunt
came
here.
二、过去式仅仅指过去的事情。而完成时是相对于现在或过去完成了的。
三、我给你几个定式：一般过去式sb.
did
sth.
一般过去式的被动语态sth.
was(were)
did
by
sb.
现在完成时sb.
have(has)
done
sth.
现在完成时的被动语态sth.
have(has)
been
done
by
sb.
过去完成时sb.
had
done
sth.
过去完成时的被动语态sth.
had
been
done
by
sb.

Answer 2

用于完成时或者做形容词修饰名词，或者是被动语态
如过去完成时,在过去的某一时间为止已经发生过的事情
she
had
learned
2000
words
by
the
end
of
last
year.
现在完成时，表示到现在为止已经发生过的事情
he
have
been
to
shanghai
twice.
过去分次作形容词
the
watered
flowers
look
very
beautiful
被动语态
the
bike
is
mended
by
me
