英语过去分词做定、表语.ppt

Grammar 过去分词具有动词的性质，同时兼有形容词或副词的性质，在句中可以作表语、定语、状语和补足语。 一、作定语修饰名词或代词 1、单个的过去分词作定语一般放在名词的前面，过去分词短语作定语通常放在被修饰的词后面. 二、作表语 1、表示主语的心理感觉或所处的状态。许多动词的过去分词已经被当作形容词使用。如：disappointed, excited, moved, puzzled, pleased, surprised, lost等。 （１）作表语的过去分词，被动意味很弱，主要表示动作的完成和状态，此时相当于一个形容词。 Practice 1. Prices of daily goods ____ through a computer can be lower than store prices. A. are bought B. bought C. been bought D. buying 3. Don’t use words, expressions or phrase ____ only to people with specific knowledge. A. being known B. having been known C. to be known D. known The End * * The Past Participle used as Attribute and Predicative 定语——在句中修饰名词或代词的成分。表语——是谓语的一部分，位于系动词之后，说明主语身份、特征或状态。 Practice 1. a retired teacher 一位退休的教师 2. an honored guest 一位受尊敬的客人 3.

Nothing reported (in the newspaper) interested him. 3、 有些过去分词作前置定语和后置定语时意义不同。 in the given time with the words given a concerned look the people concerned a wanted person workers wanted 在既定的时间内 用所给的单词 关切的神情 有关人士 被通缉的人 招聘工人 The window is broken. 窗户碎了。 Don’t get so excited. 别这么激动。 （２）被动语态的过去分词，动作意味很强，句子主语为动作的承受者，后常跟by短语。 2、过去分词作表语与被动语态的区别： The glass is broken. Our classroom is crowded The glass was broken by Jack. The windows were closed by Tom last night. （3）作表语的过去分词前可以有修饰语，而被动语态的过去分词前不能加修饰语。 The glass was broken by Tom.
