学习活动二：知识拓展

一．过去分词作定语时的意义

及物动词的过去分词作定语，在语态上表示被动；在时间上，常表示动作已经发生或完成，有时也不表示时间性。

◆Our teacher watched us doing the experiment and gave us a __________(satisfy) smile at last．

我们的老师看着我们做实验，最后给了我们一个满意的微笑。

◆The plan______( put) forward at the meeting will be carried out soon．会上提出的计划将很快被执行。2．不及物动词的过去分词作定语，它不表示被动意义，只强调动作完成。

◆Many little kids like gathering fallen leaves in the yard．许多小孩子喜欢在庭院里收集落叶。

◆The _________(rise) sun is shining brightly in the morning．早上已升起的太阳正明亮地闪耀着。【典例1】(2019·北京卷)Earth Day, ____________(mark) on 22 April, is an annual event aiming to raise public awareness about environmental protection．

二．过去分词作定语时的位置

1．前置定语

一般情况下，单个过去分词作前置定语，即放在所修饰词之前。

◆The __________(pollute) water was to blame for the spread of cholera．被污染的水造成了霍乱的传播。

◆We needed much more qualified workers．我们需要更多的合格的工人。

注意：单个的过去分词修饰复合不定代词something, everything, anything, nothing, nobody等或指示代词those时，要放在这些词的_______.

（1）He is one of those invited.

（2）There was nobody punished here.

2．后置定语

过去分词短语作定语时往往作后置定语，即放在所修饰词之后，它的作用相当于一个定语从句。◆He is a teacher________( love) by his students．他是一位受学生爱戴的老师。

◆The book _____________(publish) ten years ago is still a best-seller today．十年前出版的这本书现在仍然是一本畅销书。

It’s a picture painted by Leonardo Da Vinci.(把后置定语转化成一个定语从句）

It’s a picture_________________________ painted by Leonardo Da Vinci.

There was a woman dressed in white.

There was a woman_________________________ dressed in white.

3）I like reading the novels __________________ (write ) by Zhang Ailing.
