一般過去時(shí)的被動語態(tài)的構(gòu)成為：was/were+及物動詞的過去分詞。e.g.Thebridgewasbuiltlastyear.Thebridgewasn’tbuiltlastyear.—Wasthebridgebuiltlastyear?—Yes,itwas./No,itwasn’t.Whenwasthebridgebuilt?【拓展】1.

“不及物動詞+介詞/副詞”構(gòu)成的短語動詞，變成被動句時(shí)，要把它們作為整體看待，介詞或副詞不可拆開或漏掉。e.g.MygrandmawaslookedafterbyanursecalledLisa.Theseposterswereputupbyourheadteacher.2.

含有雙賓語的主動句變被動句時(shí)，可將主動句中的直接賓語或間接賓語變?yōu)楸粍泳渲械闹髡Z。如果把主動句中的直接賓語(指物)變?yōu)楸粍泳渲械闹髡Z，則需在間接賓語(指人)前加適當(dāng)?shù)慕樵~to或for。

e.g.主動結(jié)構(gòu)：Momboughtmeanewcoat.被動結(jié)構(gòu)：Iwasboughtanewcoat.(間接賓語作主語)Anewcoatwasboughtforme.(直接賓語作主語)3.

有些動詞常用其主動形式表示被動意義，如sell,wash,write等和表示感覺、知覺的系動詞feel,sound,taste,smell等。e.g.Thiskindofpenwriteswell.Thesweaterfeelsverycomfortable.4.

在主動句中，使役動詞(如make等)和感官動詞(如see,watch,notice,hear等)后面常接不帶to的動詞不定式作賓語補(bǔ)足語；但在被動句中，這些詞后面的動詞不定式都需要帶to。e.g.Tomwasmadetoanswerthequestionsinclassbytheteacher.Timwasseentorunintheplaygroundlastweekend.Grammar英語動詞有兩種語態(tài)：主動語態(tài)（ActiveVoice)和被動語態(tài)(PassiveVoice)。主動語態(tài)表示主語是動作的執(zhí)行者，而被動語態(tài)則表示主語是動作的承受者。

e.g.Wecleanedtheclassroomyesterday.(主動語態(tài)，主語we是clean這一動作的執(zhí)行者)Englishisspokenbymanypeople.(被動語態(tài)，主語English是動作speak的承受者。二、被動語態(tài)的構(gòu)成

助動詞be+及物動詞的過去分詞構(gòu)成。助動詞be有人稱、數(shù)、和時(shí)態(tài)的變化。

一、語態(tài)三、被動語態(tài)的用法：1.不知道誰是動作的執(zhí)行者，或沒有必要指出誰是動作的執(zhí)行者。

e.g.ThiskindofcarismadeinAmerica.

這款小汽車產(chǎn)自美國。2.需要突出或強(qiáng)調(diào)動作的承受者。

e.g.Thisdictionaryisusedbymoststudents.

這本字典是大多數(shù)學(xué)生在用的。四.主動語態(tài)變被動語態(tài)的步驟.Bellinventedthetelephonein1876.ThetelephonewasinventedBellin1876.

主動語態(tài)變被動語態(tài)的步驟：1、主動語態(tài)的賓語變?yōu)楸粍诱Z態(tài)的主語；2、主動句的謂語動詞變?yōu)楸粍邮浇Y(jié)構(gòu)，即：be+及物動詞的過去分詞

3、主動句的主語變?yōu)楸粍泳渲衎y的賓語，當(dāng)不

強(qiáng)調(diào)動作的執(zhí)行者時(shí)，常省略。4.其它成分不變。Summary五、一般過去時(shí)被動語態(tài)的幾種句型結(jié)構(gòu)：肯定句主語+be(was,were)+及物動詞的過去分詞+(by…)Acakewaseatenbyamouselastnight.否定句
