1.前置定語歸納1：單個的過去分詞作定語時，通常放在被修飾的名詞_______。之前單個過去分詞作定語，常放在被修飾詞的前面;過去分詞短語作定語，常放在被修飾詞的后面。Englishisawidelyusedlanguage.Thisisoneoftheschoolsbuiltin1980.3.過去分詞作定語位置apicturepaintedbyLeonardodaVinciawomandressedinwhite2.過去分詞短語作定語：通常_____，其作用相當于定語從句。1)It’sapicture_______________paintedbyLeonardodaVinci2)Therewasawoman____________dressedinwhitethat/whichwasthat/whowas后置單個過去分詞修飾something,everything,anything,nothing,somebody,nobody，those

等不定代詞時，也要放在這些詞后面。Nothingreported(inthenewspaper)interestedhim.教育定語

→Theinjuredboy

cannottakepartinthesportsmeet.AllbookswhichwereborrowedfromthelibraryshouldbereturnedbyFriday.Example

Theboywhoisinjuredcannottakepartinthesportsmeet.→Allbooksborrowedfromthelibrary

shouldbereturnedbyFriday.位于系動詞后，不表示“被動”或“完成”，而是表示主語的狀態(tài)、特點或思想感情等。相當于形容詞1.Theyareexcited.2.Helookedworriedafterreadingthe

letter.3.Whenweheardofthis,weweredeeplymoved.二.過去分詞作表語系動詞的分類：“似乎類”：“感覺類”：

“變成類”：“仍然類”：基本形式：Be(am,is,are)seem,appear,lookfeel,sound,smell,tastebecome,go,get,grow,fall,turnremain,stay,keep4.過去分詞作表語1.用作表語的過去分詞被動意味很弱，主要表示動作的完成和狀態(tài)，此時相當于一個形容詞。2.被動語態(tài)的過去分詞被動意味很強,句子主語為動作的承受者，后面常跟by短語。①Theglasswasbroken.TheglasswasbrokenbyTom.②Thewindowsareclosed.ThewindowsareclosedbyJack.狀態(tài)動作動作狀態(tài)[辨析]:

過去分詞作表語與被動語態(tài)的區(qū)別：前者表示主語的狀態(tài)和特征,可被very修飾;而后者則表示動作,不能被程度副詞very修飾。試比較：

MissGreenwasverypleasedwiththedishwhichwascookedbyherself.(wasverypleased)是系表結(jié)構(gòu);而wascooked是被動語態(tài),表動作,不能把very放在cooked之前。

過去分詞作表語與動詞-ing作表語的區(qū)別：過去分詞作表語,表示被動或完成,有時表示主語(人)所處的心理狀態(tài);而動詞-ing作表語,表示主動或進行。如：Mr.Smithwasverytiredofthespeechthatwasboring.[辨析]:同步作業(yè)一、單句填空
