过去分词作定语：
1.
过去分词作定语时，表示的动作在谓语动作之前发生，已经完成并具有被动意义。此时，作定语的过去分词一般是由及物动词变来的，因为只有此类动词才有被动意义。
2.
单个的过去分词作定语一般放在被修饰的名词之前。过去分词短语作定语要放在被修饰的名词后面，作后置定语，表示被动或完成，其作用相当于一个定语从句。
【拓展】
1.
不及物动词的过去分词也可作定语，一般
作前置定语，不表示被动意义，只强调动
作完成。如：fallen
leaves落叶；retired
workers退休工人；the
risen
sun升起的太
阳。
2.
如果被修饰的词是由every
/
some
/
any
/
no
+
thing
/
body
/
one所构成的复合代词或指
示代词those或these等时，即使是单一的过
去分词作定语，也要放在被修饰词的后
面。
过去分词作表语：
过去分词作表语时，与谓语动词构成系表结
构，表示主语的性质、特征和状态。
可以用作表语的常见的过去分词有：
delighted,
disappointed,
upset,
astonished,
excited,
frightened,
experienced,
interested,
qualified,
puzzled,
exhausted,
satisfied。
【辨析】
1.
过去分词作表语时与被动语态的区别：过去分词作表语，主要是表示主语的状态和特征,
而被动语态则表示动作。如：
The
cup
was
broken
by
my
little
sister
yesterday.
The
library
is
now
closed.
2.
过去分词作表语与动词-ing形式作表语的区别：过去分词作表语表示被动或完成，动词-ing形式作表语表示主动或进行。如：
She
was
embarrassed
because
she
didn’t
know
the
answer.
Today’s
meeting
was
boring.
people
terrified
of
(cholera)
