verb-edform
一、v-ed分词具有形容词和副词性质，在句中可充当定语、表语、宾语补语、状语。
1.作定语
过去分词作定语，表示已经完成的被动的动作或状态,但不及物动词构成的过去分词只表示完成，而不表示被动意义。
例如：完成+被动： apollutedriver     alockedroom  awell-educatedman
      只有完成：  aretiredworker    afallenleaf    boiledwater
作定语的v-ed分词也有前置和后置两种情况。单个过去分词作定语，常常位于被修饰的名词前；而过去分词短语作定语时，常常位于被修饰的名词后面，相当于一个定语从句。
eg.1).youshouldimproveyourspoken(speak)english.
  2).what’sthelanguagespoken(speak)inthatarea?
=.what’sthelanguagewhich/thatisspoken(speak)inthatarea?
3).thefiremenweretryingtorescuethepeopletrappedinthefire.
=thefiremenweretryingtorescuethepeoplewhowastrappedinthefire.
4).themeeting,attendedbyonethousandstudents,wasasuccess.
=themeeting,whichwasattendedbyonethousandstudents,wasasuccess.
2.作表语
作表语的v-ed分词大多转化成为形容词，通常用于联系动词之后（例如be,seem,appear,look,sound,feel,remain,stay,become,get等），表示主语所处的状态
1).edisonbecameinterested(interest)insciencewhenhewasveryyoung.
2).shelooksveryexcited(excite)atthenews.
3).wheniwascleaningthewindow,myfingergotcut(cut)unexpectedly.
3.作宾语补足语
如果宾语与后面作宾补的动词构成被动关系，则使用v-ed分词作宾补。可以带v-ed分词作宾补的词有：with,see,watch,observe,notice,lookat,hear,listento,feel,sense,find,leave,keep,get,have,make.
1).ihadmymoneystolen(steal)onthebus.
2).asheknowslittleenglish,hefindsitdifficulttomakehimselfunderstood(understand).
3).inthemorning,peoplewokeupandfoundtheworldoutsidetheirhousescompletelychanged(change).
4.作状语
作状语的v-ed分词与主句之间常有逗号隔开,在句中可表示时间,原因,条件,让步,伴随等情况,并可转化为相应的状语从句。作状语的v-ed和主句的主语常有被动关系。
1) 时间状语
seenfromspace,theearthlooksblue.
=whentheearthisseenfromspace,itlooksblue.

askedwhathadhappened,heloweredhishead.
=whenhewasaskedwhathadhappened,heloweredhishead.
2)原因状语
bornintoapoorfamily,hehadonlytwoyearsofschooling.
=ashewasbornintoapoorfamily,hehadonlytwoyearsofschooling.
