过去分词在句中的作用和用法：

过去分词表示完成和被动的含义，具有形容词和副词的作用。在句中用作定语、表语、宾语补足语，但是不能单独构成谓语。

Mary felt very disappointed to see the newly computer she had had______went wrong again. A.it B.it repired C.repaired D.to be repaired 解析：C.she had had______是定语从句，后一个had是使役动词have的过去分词，用到have sth done结构，句意是：玛丽再一次看到她让人修理的洗衣机又坏了，感到很失望。

过去分词做定语：

过去分词作定语有两种形式：一、可以放在被修饰的名词之前,称为前置定语；二、有的放在被修饰的名词之后,称为后置定语。

(1)

前置定语:单个过去分词及由过去分词构成的复合形容词作定语时,通常置于被修饰词之前。

非谓语动词有哪几种形式？

过去分词在句中可以做什么成分？

the developed countries

well-trained teachers

man-made satellites

invited guests

used text books

后置定语:当单个过去分词及由过去分词修饰代词时,需置于被修饰词之后;过去分词短语作定语要后置。

The temple built last month needs repairing.

(2)

部分过去分词作定语有的既可前置也可后置，意义不变,但部分过去分词置于被修饰词前后的位置不同,则意义也不相同。

All the broken roofs have been repaired. =All the roofs broken have been repaired. an adopted child

(4)分词短语作定语必须置于被修饰词之后,相当于一个被动语态的定语从句。如: ① The first textbooks written for teaching as a foreign language came out in the 16th century. = The first textbooks that/which were written for teaching as a foreign language came out in the 16th century. ② The Olympic Games, first held in 776 BC, did not include women competitors until 1912. = The Olympic Games, which were first held in 776 BC, did

not include women competitors until 1912? (5)复合的分词一般不作定语,若要表达完成意义最好用定语从句。

我们一般不说:The girl having won the race is my desk mate. 而常这样说:The girl who has won the race is my desk mate. (6)一些不及物动词的过去分词作定语时在意义上只表示完成，不表被动。

①

表示被动也表示完成: the question discussed yesterday he broken glass the person killed last year ②只表示完成,不表示被动: newly-arrived goods fallen leaves three faded roses Exercises: Don’t use words, expressions or phrases________only to people with specific knowledge. A. known

B.having been known

C.to be known D.being known 答案解析：A.过去分词作定语,known修饰words, expressions or phrases.句意:不要用只有具备专业知识的人员

才懂得的单词/短语和词组. Coffee, ______with tea, tastes terrible. A. mixed B.mixing C.mix D.is mixed 答案解析：mixed 是过去分词，意为：被混合了的，coffee是主语，tastes是谓语，mixed with tea过去分词短语修饰主语coffee，D选项涉及时态和语态，做的是句子的谓语动词。

Most of the people ______to the activity were famous lecturers. A. invited B.being invited C.to invite D.inviting 答案解析：A. invited是过去分词做定语，修饰Most of the people. 作业：完成课本上有关过去分词做定语的练习，并考虑这些过去分词或过去分词短语是否能用定语从句来表达。
