(2)过去分词作时间状语Seen from space ,the earth looks blue.When it is seen from space,the earth looks blue.(3) 过去分词作条件或假设状语Compared with you,we still have a long way to go.If I am compared with you,we still have a long way to go.(4) 过去分词作方式或伴随情况状语Followed by his little sister,the dog was running happily.The dog was followed by a little sister and he was running happily.(5) 过去分词作让步状语Exhausted by the climb,we continued our journey.Although we were exhausted by the climb,we continued our journey.2，summary a,过去分词在句子中可作时间状语，原因状语，伴随状语，条件状语，让步状语等。 B,过去分词作状语时，过去分词的逻辑主语与句子主语一致。 C,过去分词作状语有两大特点：（1），表示被动的动作，分词与主语逻辑关系被动（2），表示已经完成的动作3，Rewrite the sentences with proper conjunctions.（1）Asked what had happened,he told us about it._When he was asked what had happened ,he told us about it. （2）Well-known for his expert advice,i received many invitations to give lectures._Because he was well known for his expert advice,he received many invitations to give lectures. （3）Given more time,we would be able to do the work much better ._If we were given more time,we would be able to do the work much better. （4）Once translated into Chinese, the book became very popular among Chinese teenagers._Once it was translated into Chinese,the book became very popular among Chinese teenagers.（5） Deeply interested in medicine ,she decided to become a doctor._Because she was deeply interested in medicine,she decided to become a doctor. （6）Left alone at home,Sam did not feel afraid at all._Although he was left alone at home,Sam did not feel afraid at all.4,Rewrite the sentences with past participle.（1） As I was worried about the journey,I was unsettled for the first few days._Worried about the journey, I was unsettled for the first few days.（2） If he is given time, he will make a first -class tennis player._Given time,he will make a first class tennis player. （3）As I was confused by the new surroundings,I was hit by the lack of fresh air._Confused by the new surroundings,I was hit by the lack of fresh air.（4） When he was questioned by the police about the fire, he became tense._Questioned by the police about the fire,he became tense.四）探究发现四-过去分词与现在分词作状语的区别 作状语的过去分词，其逻辑主语通常就是句子的主语，且主语是过去分词的动作承受者，即过去分词表示的动作不是句子的主语发出的，过去分词与主语之间是动宾关系，即被动关系。这一点是与现在分词作状语的情况是不同的，后者与主语之间是主谓关系。Compare:(1),Following the old man,we went upstairs.跟着那个老人，我们上了楼。(2)，Followed by the old man,we went upstairs.被那个老人跟着。我们上了楼。(3)，从上面看，体育场好像一个鸟巢。from the top ,the stadium looks like a bird nest. A,seeing B,seen(4),从太空看，宇航员看不到长城。from the space,the astronaut could not discover the Great Wall.A, seeing B, seen五）探究发现五-过去分词作定语（一），过去分词作定语与其所修饰的词之间存在着逻辑上的被动关系，且表示该动作已经完成。Spoken English 英语口语A retired teacher 一个退休的老师（1） 前置定语 单个的动词-ed 形式，一般放在被修饰名词前面。 The excited people（激动的人们）rushed into building. =the people who were excited Lost time （虚度的时光）can never be found again. =time which is lost （2）后置定语 动词-ed 形式短语作定语时，常放在被修饰名词的后面，相当于一个定语从句。 1，Is there anything that has been planned for tonight? Is there anything planned for tonight? 2,The meeting,which was attended by a lot of people,was a success. The meeting,attended by a lot of people,was a success. （二）Combine these sentences using the past participle as the attribute.（page 21 Ex3.）六）探究发现六-现在分词与过去分词作定语的区别 (1),现在分词作定语，它与被修饰的名词存在着逻辑上的主谓关系，该动词的动作正在进行。 过去分词作定语时，它与被修饰的名词存在着逻辑上的动宾关系，该动作已经发生。 He worked as a worker building roads.= He worked as a worker who/that built roads. This is a picture painted by my father.=This is a picture which was painted by my father. (2),Combine these sentences using the past participle as the attribute.（page 21 Ex3.）Step3:课堂练习： (1)Filling in the blanks:1,I like reading the novels _（write）by Zhang Ailing.2,The girl_（write）a letter in study is my cousin.3,There is something wrong with my car and I have to get it _（repair） (2)make a dialogue: Cathy went to the seaside with his husband to spend the weekend, After having a swim,she began reading a moving story on the beach.Suddenly,she heard someone calling for help.“Someone must be drowning!”her husband said. “It is really surprised news!”she added.
