語法

一．過去分詞作定語過去分詞作定語與所修飾的詞之間有兩種關(guān)系:從時間上講,表示動作已經(jīng)完成;從語態(tài)上講,表示被動的概念。分詞作定語有兩種形式：它可以放在被修飾的名詞之前,稱為前置定語；有的放在被修飾的名詞之后,稱為后置定語。

(1)前置定語:單個過去分詞及由過去分詞構(gòu)成的復(fù)合形容詞作定語時,通常置于被修飾詞之前。如:thedevelopedcountries發(fā)達(dá)國家;well-trainedpolicemen訓(xùn)練有素的警察man-madesatellites人造衛(wèi)星;invitedpeople被邀請的人Weonlysellusedbooks.我們只賣用過的書。

(2)后置定語:當(dāng)單個過去分詞及由過去分詞修飾代詞時,需置于被修飾詞之后;過去分詞短語作定語要后置。如:Don’tusewords,expression_rsorphrasesknownonlytopeoplewithspecificknowledge.不要運(yùn)用只有具有特別知識的人才能懂的詞匯和表達(dá)方式。Thebridgebuiltlastmonthneedsrepairing.

上個月建造的那座橋需要修理。(3)部分過去分詞作定語有的既可前置也可后置，意義不變,但部分過去分詞置于被修飾詞前后的位置不同,則意義也不相同。如:Allthebrokenwindowshavebeenrepaired.=Allthewindowsbrokenhavebeenrepaired.所有壞了的窗戶已經(jīng)修理好了。anadoptedchild收養(yǎng)的孩子;

aplanadopted被采納的方案(4)分詞短語作定語必須置于被修飾詞之后,相當(dāng)于一個被動語態(tài)的定語從句。如:①Thefirsttex
