Sectin Ⅱ　Discvering Useful Structures
语法点拨过去分词是非谓语动词的一种形式。从语法功能分析，过去分词兼有动词、形容词或副词的特性，可在句中充当定语、表语、宾语补足语或状语。过去分词通常与逻辑主语之间存在被动关系，表示被动或完成。
过去分词作定语和宾语补足语
一、过去分词作定语1．过去分词作定语时的位置(1)前置定语一般情况下，单个过去分词作前置定语，即放在所修饰词之前。The plluted water was t blame fr the spread f chlera.被污染的水造成了霍乱的传播。The recvered animals will be released sn.痊愈的动物会很快被释放。
①有些过去分词表示特定含义时，单独作定语也放在所修饰的名词之后，如left(剩余的)，given(所给的)，cncerned(有关的)等。There are few tigers left. It is time fr the departments cncerned t take measures t prtect them frm dying ut.剩余的老虎不多了，是相关当局采取措施保护它们免遭灭绝的时候了。
②如果被修饰的词是由every/sme/any/n与thing/bdy/ne所构成的复合代词或指示代词thse等，单个分词放在被修饰词的后面。Is there anything unslved?还有什么没解决的吗？
(2)后置定语过去分词短语作定语时往往作后置定语，即放在所修饰词之后，它的作用相当于一个定语从句。Last Tuesday in a muntainus area, there were a ttal f 173 sheep killed almst immediately(＝which were killed almst immediately) when lightning struck.上周二在一个山区，当雷击发生时有173只羊即刻被雷电击死。
2．过去分词作定语时的意义(1)及物动词的过去分词作定语，在语态上表示被动；在时间上，常表示动作已经发生或完成，有时也不表示时间性。Trucks and buses were driven n gas carried in large bags n the rf.(表被动)卡车与公共汽车皆烧燃气，燃气装在车顶上的大袋中。The plan put frward at the meeting will be carried ut sn.(表被动和完成)会上提出的计划将很快被执行。
(2)不及物动词的过去分词作定语，它不表示被动意义，只强调动作完成。Our retired sccer cach went t watch us play a game last week.上周我们已退休的足球教练去看我们打了一场比赛。The risen sun is shining brightly in the mrning.早上已升起的太阳正明亮地闪耀。
3．过去分词与现在分词作定语的区别
As we all knw, China is a develping cuntry.众所周知，中国是一个发展中国家。The visitr came frm a develped cuntry.这位游客来自一个发达国家。
4．过去分词(dne)、现在分词的被动语态(being dne)与动词不定式的被动语态(t be dne)作定语的区别
The building built last year is ur classrm building.去年建造的楼是我们的教学楼。The building being built nw is ur classrm building.现在正在建造的楼是我们的教学楼。The building t be built next mnth is ur classrm building.下个月将要建造的楼是我们的教学楼。
