Answer 1

提问不规范
回答也不规范
那能说现在完成时加过去分词
那是神马
现在完成时必须有过去分词
它的构成
主语+have/has+过去分词
完成时态中
如含有一段时间的for短语和since短语
时
动词必须是延续性动词
如
he
has
died
for
two
days
错
应是
he
has
been
dead
for
two
days.
he
has
bought
the
car
for
two
years

应是
he
has
had
the

he
has
come
here
for
two
days

应是
he
has

延续性动词的用法很广，但常见于现在完成时中的句子中，且常与for，how，long，since等引导的表示一段时间的状语或状语从句连用。
然而你所说的过去分词，则是瞬间动词。既然是瞬间动词，那么就不能直接与for或since连用。反过来说，当你动词需要和for或since连用时，你需要改变动词，如：用keep或have代替borrow
I
have
kept(不能用have
borrowed)
the
book
for
quite
a
few
days.
