内容
Grammar学习过程
学法指导:
一.自主探究——问题发现过去分词作定语,在语态上,表被动;在时间上,表示动作已经发生或完成,与它所修饰的名词有逻辑(意义)上的动宾关系。过去分词作定语时,所修饰的名词在逻辑上相当于被动句中的主语,过去分词相当于谓语。
过去分词作定语表示动作在谓语动作之前发生,已经完成并具有被动意义。有时也不表示时间性。作定语的过去分词一般由及物动词变来,因为只有及物动词才有被动意义。例如:
Heisateacherlovedbyhisstudents.他是个很受学生爱戴的老师。
也有用不及物动词的过去分词作定语的情况,一般作前置定语,它不表示被动意义,只表示主动意义,强调动作完成。不能像及物动词的过去分词那样放在名词后面作定语。例如:
fallenleaves________retiredworkers________
therisensun________
注意下面过去分词作定语的几种情况:
1.单个的过去分词作定语一般放在被修饰的名词之前。例如:
Weneededmuchmorequalifiedworkers.________________________。
Myfriendisareturnedstudent.________________________
单个分词也可以作后置定语,用以强调动作。例如:
Theydecidedtochangethematerialused.他们决定更换使用的材料。
2.过去分词短语作定语要放在被修饰的名词后面,作后置定语,其作用相当于一个定语从句。例如:
Thestudentdressedinwhiteismydaughter.
=Thestudentwhoisdressedinwhiteismydaughter.)穿白色衣服的学生是我的女儿。
3.如果被修饰的词是由every/some/any/no+thing/body/one所构成的复合代词或指示代词those等时,即使一个单一的分词作形容词用,也要放在被修饰词的后面。例如:
Isthereanythingunsolved?还有没解决的问题吗?
ThereisnotingchangedheresinceIleftthistown.自从我离开这个城镇以来,几乎没有什么变化。
4.单个过去分词前加一名词或副词,常用连字符将它们连接起来构成一个复合形容词,放在其修饰的名词前,作前置定语。分词前加的名词表示分词的动作或行为主体,所加的副词表示方式、时间、程度、性质等意义。例如:
Thisisastate-ownedfactory.这是一家国营工厂。
Thisisourschool-runfactory.这是我们的校办工厂。
5.作前置定语的某些动词的过去分词的形式与作谓语或表语的过去分词的形式往往不一样。例如:
原形用作定语的过去分词用作表语或谓语的过去分词
drinkdrunkendrunklightlightedlight/litmeltmeltedmeltedsinksunkensunk
Welitthecandleandthecandlelituptheroom.我们点着蜡烛,蜡烛照亮房间。
