1、1创新设计Part Using language动词-ed形式作状语2创新设计【思维导图】3创新设计名师提醒动词ed形式属于非谓语动词的一种。所谓非谓语动词，就是指在句子中不作谓语的动词。由于非谓语动词不能单独用作谓语，所以从理论上说，它也就没有实际意义上的主语。4创新设计1.动词-ed形式是分词的一种。规则动词的过去分词一般是由动词加-ed构成(规则见后)，不规则动词的过去分词见不规则动词表。2.动词-ed形式作状语，相当于状语从句或并列句；通常情况下，其逻辑主语就是句子的主语，与主语间为被动关系；该动作表示被动、完成；分词可位于句首和句后；动词-ed形式与动词-ing形式在句中都可作状语，

3、ed，supported by the nurse.6.The cup fell down to the ground，broken.6创新设计【自我总结】1.所有句子中动词-ed形式都作状语，其逻辑主语都是句子的主语，与主语间为被动含义。2.动词-ed形式的位置可以在句子开头、中间和末尾。3.以上句子中的动词-ed形式分别作_、_、_、_、_、_状语。原因时间条件让步方式结果7创新设计二、主要用法精讲【重点归纳】1.动词-ed形式作状语的意义动词-ed形式作状语来源于状语从句或并列句。可以表示时间、原因、条件、让步、方式或伴随情况等。表示时间、原因、条件、让步时，动词-ed形式可以拓展成相应

4、的状语从句，表示方式、结果和伴随时可转化为并列分句。8创新设计(1)作时间状语时，相当于when或while等引导的从句。Seen from the top of the hill(When it is seen from the top of the hill)，the school looks like a big garden.(2)作条件状语时，可转换为once，if或unless等引导的从句。Given more attention(If it was given more attention)，the fire could have been avoided.(3)作原因状语时，可

5、转换为because，as或since等引导的从句。Encouraged(As she was encouraged)by the teacher，the girl was very happy.9创新设计(4)作让步状语时，可转换为though，although 或even if引导的从句。Left(Although she was left)alone at home，Jenny didnt feel afraid at all.(5)作方式或伴随状语时，常可转换为并列分句，可位于句首或句末。Surrounded by his students，the teacher went into

6、the lab.(The teacher was surrounded by his students and he went into the lab.)10创新设计2.动词-ed形式与主语间的关系通常情况下，其逻辑主语必须与句子主语保持一致，也就是说，动词-ed形式与句子的主语之间是动宾关系，主语与动词间是被动含义。Encouraged by their teacher，the students worked even harder.受老师的鼓励，学生们学习更努力了。由句子含义可看出，句子主语the students是动词encourage的宾语，即动作的承受者，encourage the

7、 students鼓励学生，故主语the students与encourage之间为被动含义。Given another hour，I can also work out this problem.再给我一个小时，我也能解这道题。同样，句子主语I和分词动作give间为被动关系。11创新设计3.动词-ed形式作状语表示被动、完成的动作(1)及物动词的动词-ed形式既表被动，也表完成。Written in a hurry，this article was not so good!因为写得匆忙，这篇文章不是很好。(2)不及物动词的动词-ed形式只表完成，不表被动。The boy is gatheri

8、ng fallen leaves(leaves that have fallen).小男孩正在收集落叶。12创新设计4.动词-ing形式与动词-ed形式作状语的区别动词-ing形式作状语与动词-ed形式作状语的最主要区别在于：两者与所修饰的主句的主语的逻辑关系不同。(1)动词-ing形式作状语时，动词-ing形式所表示的动作与句子主语之间构成逻辑上的主动关系。He went out，shutting the door behind him.他出去后将门随手关上。Not knowing what to do，he went to his parents for help.由于不知如何办是好，他去

9、找父母帮忙。13创新设计(2)动词-ed形式作状语时，动词-ed形式所表示的动作与句子主语之间构成逻辑上的被动关系。Given more encouragement，the boy could have behaved better.如果多给这个男孩一些鼓励，他可能会表现得更好。Asked why he did it，the monitor said it was his duty.当被问及为什么做这件事时，班长说这是他的职责。14创新设计比较：Used for a long time,the book looks old.由于用了很长时间，这本书看上去很旧。Using the book,I

10、find it useful.在使用的过程中，我发现这本书很有用。【名师提醒】选择动词-ing形式还是动词-ed形式，关键看主句的主语。如果分词的动作是主句的主语发出，分词就选用动词-ing形式，反之就用动词-ed形式。15创新设计即学即练1用状语从句替换句中黑体部分Asked why he was late，he went red._United，we stand；divided，we fall._Inspired by what he said，we are determined to study hard._When he was asked why he was lateIf we a
