高二英语人教版选修8unit3Section ⅢGrammar精讲精练(含答案)
Section ⅢGrammar——过去分词作定语、表语和宾语补足语考点一过去分词作定语1．过去分词作定语时，相当于形容词，其逻辑主语就是它所修饰的名词。
分词所表示的动作与其所修饰的名词构成动宾关系。
The concert given by their friends was a success.他们朋友举办的音乐会很成功。
2．单个的过去分词作定语时，常常置于其所修饰的名词前；而过去分词短语作定语时，常常置于其所修饰的名词后。
They are cleaning the fallen leaves in the yard.他们正在打扫院子里的落叶。
The meeting，attended by over five thousand people，welcomed the great hero.(他们举行了)欢迎英雄的大会，到会的有五千多人。
3．过去分词及过去分词短语作定语一般可转换为一个定语从句。
We must adapt our regulations to the changed conditions.＝We must adapt our regulations to the conditions that have been changed.我们必须调整规章制度来适应变化了的情况。
4．有些过去分词作前置定语与后置定语时意义不同。
in the given time在既定的时间内with the words given用所给的单词a concerned look一个关切的神情the people concerned有关人士[名师点津]及物动词的过去分词除表示“完成”的动作之外，还表示“被动”的意义。
如：spoken English(英语口语)；iced beer(冰冻啤酒)；cooked food(熟食)；fried chips(炸土豆条)。
不及物动词的过去分词常表示“完成”的动作，而不表示“被动”意义。
