+(by…)3.一般疑問句:Was/Were+主語+Ved

+(by…)?Thenewswasn’tpublishedbythegovernment.Wasthenewspublishedbythegovernment?特殊疑問句:疑問詞+was/were+主語+Ved

+(by…)?Whenwasthenewspublishedbythegovernment?一般過去時被動語態(tài)結構:“主語+was/were+及物動詞的過去分詞(+by+動作的執(zhí)行者).”常見幾種句型結構：一、一般過去時被動語態(tài)句子結構用法例句不知道動作的執(zhí)行者Thesebookswerewrittenforchildren.強調動作的承受者ThebookwaswrittenbyMoYan.動作的執(zhí)行者是無生命的事物Manytrafficaccidentswerecausedbycarelessdriving.二、被動語態(tài)的用法：

Edison

thelightbulb.Thelightbulb

wasinvented

byEdison.主語謂語動詞主動語態(tài)(過去時)賓語主語謂語動詞被動語態(tài)(be+Ved)介詞+賓語◆主動語態(tài)變被動語態(tài)的方法①主動語態(tài)的主語變成by引導的介詞短語放在主謂結構后面，有時可以省略。②主動語態(tài)的謂語動詞變成“was/weredone”形式。③主動語態(tài)的賓語變成被動語態(tài)的主語。三、主動語變被動語態(tài)方法及注意問題1.有些短語動詞相當于及物動詞，變?yōu)楸粍泳鋾r介詞或副詞不能去掉。

e.g.Theyputoffthemeetingbecauseoftheweather.→Themeetingwasputoffbecauseoftheweather.

會議因天氣的緣故被推遲了。主動語態(tài)變被動語態(tài)應注意的問題2.含有雙賓語的主動句變?yōu)楸粍泳鋾r，通常把指“人”的間接賓語變?yōu)橹髡Z，指“物”的直接賓語保留不變；如果把指“物”的直接賓語變?yōu)橹髡Z，則在間接語前加to或for。e.g.Myauntgavemeanedictionaryyesterday.

Iwasgivenanedictionaryyesterday.

Anedictionarywasgiventomeyesterday.3.主動句中感官動詞see/hear/watch/feel等和使役動詞make/let/have等后跟省略to的動詞不定式，變?yōu)楸粍诱Z態(tài)時應加上不定式標志to。e.g.Isawaheavymanenterthehouse.

Aheavymanwasseentoenterthehouse.4.系動詞、不及物動詞或某些短語動詞（happen,takeplace,etrue,fallasleep…）沒有被動語態(tài)。e.g.WhathappenedtoMr.Brown?

布朗先生發(fā)生了什么事？主動語態(tài)變被動語態(tài)應注意的問題主動語態(tài)不能變成被動語態(tài)的情況當賓語是反身代詞或相互代詞時Hemadehimselfacupofcoffee.Theyhelpeachother.當賓語是不定式或Ving時Weallwanttobeteachers.當某些動詞表示狀態(tài)或結果時Themilktastesslightlysour.當賓語表示數量、重量、大小或程度Thejadeweighsoneton.Rewritethesentencesusingthepassivevoice.1.Theysoldthefridge
