过去分词作定语

1单个的过去分词作定语一般放在所twomarriedwomen

修饰的名词之前；过去分词短语作afoundumbrella

定语一般要后置。ausedstamp

fallenleaves

anovelwrittenbyJim

thelettersenttoourboss

2过去分词具有被动或完成的含义。WhafsthelanguagespokeninGermany?

Theydecidedtorebuildthedamagedbridge.

3过去分词作定语常可扩展为一个定Heisfondofthefoodcooked(=whichhadbeencooked)

语从句。byyourmother.

Thereportisthebestofitskindeverwritten(=thathas

everbeenwritten).

4有时通过一个形容词或数词加另一athree-leggeddeskaone-eyeddog

名词的ed形式构成复合形容词。anhonest-facedmanawarm-heartedlady

Explaintheusageofthepastparticiplesaspredicativeandattribute.

1.过去分词作表语表示主语所处的状态。用作表语的过去分词大多来自及物动词；不及物

动词的过去分词能作表语的只限于少数表示位置转移的动词，如go,come,assemble等，

它们用在连系动词之后，表示完成意义，无被动意义。例如：

Themanlookedquitedisappointed.

Heisgreatlydiscouragedbyherrefusal.

Hishairisnearlyallgone.

已经形容词化了的过去分词大多可作表语，常见的有accomplished,amazed,amused,

astonished,broken,closed,completed,complicated,confused,crowded,devoted,disappointed,

discouraged,drunk,excited,frightened,hurt,interested,lost,satisfied,surprised,worried等。

2.过去分词作定语

a）用作前置定语的过去分词通常来自及物动词，带有被动意义和完成意义。例如：

Welikeskatinginthefrozenlakeinthewinter.

=Wclikeskatinginthelakewhichhasbeenfrozeninthewinter.

Howmanyfinishedproductshaveyougotuptonow?

=Howmanyproductsthathavebeenfinishedhaveyougotuptonow?

来自不及物动词的过去分词很少能单独用作前置定语，能作这样用的仅限以下几个词，这时

仅表示完成意义，不表示被动意义。例如：

aretiredworker=aworkerwhohasretired

anescapedprisoner=aprisonerwhohasescaped

afaded/witheredflower=aflowerthathasfaded/withered

fallenleaves=leavesthathavefallen

therisensun=thesunthathasjustrisen

areturnedstudent=astudentwhohasreturned

vanishedtreasure=treasurethathasvanished

b）用作后置定语的过去分词通常也来自及物动词，表示被动意义和完成意义。这时过去分

词相当于一个定语从句。例如：

Thingsseenarebetterthanthingsheard.

=Thingswhichareseenarebetterthanthingswhichareheard.

Thelobsterbroiledovercharcoalwasdelicious.

=Thelobsterwhichwasbroiledovercharcoalwasdelicious.
