过去分词的句法功能

过去分词的句法功能

过去分词是一种非谓语动词，在句中不能单独做谓语。但它具有形容词和副词的特性，故在句中可以作定语、表语、宾语补足语和状语。

（一）定语

作定语用的过去分词如果是单个的词，就放在被修饰的词的前面；若为分词短语则放在所修饰的词的后面。如：

The excited children are opening their Christmas presents.

兴奋的孩子们正在打开他们的圣诞礼物。

Some of the people invited (=who have been invited) to the party can’t come.

有些被邀请参加晚会的人不能来。

注意：（1）做定语用的过去分词通常指已完成的动作，若要表示现在进行的动作则要用过去分词的进行形式。

We must keep a secret of the things being discussed here.

=We must keep a secret of the things which are being discussed here. 我们必须对这里讨论的问题保密。

（2）如指未来的情况，都用不定式的被动形式。

He prepared some poems to be recited at the English evening. 他准备了几首将在英语晚会上朗诵的诗。

例1．The computer centre, ______ last year, is very popular among the students in this school.
