Thetelephone__________________AlexanderGrahamBellin1876.inventedwasinventedbyGrammar英語有兩種語態(tài)：主動語態(tài)和被動語態(tài)。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。如：Wecleanedtheclassroomyesterday.我們昨天打掃了教室。(主動語態(tài)，主語we是clean這一動作的執(zhí)行者)Theclassroomwascleanedyesterday.教室昨天被打掃。(被動語態(tài)，主語theclassroom是clean這一動作的承受者)一般過去時被動語態(tài)的結構為“主語+was/were+及物動詞的過去分詞(+by+動作的執(zhí)行者).”。如：Treeswereplantedlastspring.去年春天種了樹。一、一般過去時被動語態(tài)1.肯定句：

主語+was/were+及物動詞的過去分詞+其他.e.g.PaperwasinventedbyChinesepeopletwothousandyearsago.

紙是中國人在二千多年前發(fā)明的。

2.否定句：

主語+was/werenot+及物動詞的過

去分詞+其他.e.g.

Womenwerenotallowedtotakepartinthegamesatfirst.

開始婦女不允許參加奧運會。e.g.

Wasthispicturedrawnbyyoursister?

這幅畫是你妹妹畫的嗎？

3.一般疑問句：

Was/Were+主語

+及物動詞的過去分

詞+其他?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.Englishisspokenallovertheworld.

全世界都在說英語。2.需要突出或強調動作的承受者。

e.g.Thisdictionaryisusedbymoststudents.

這本字典是大多數(shù)學生在用的。二、被動語態(tài)的用法：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。三、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.Myauntgavemeane-dictionaryyesterday.

Iwasgivenane-dictionaryyesterday.

Ane-dictionarywasgiventomeyesterday.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,cometrue,fallasleep…）沒有被動語態(tài)。e.g.WhathappenedtoMr.Brown?

布朗先生發(fā)生了什么事？將下列句子變?yōu)楸粍诱Z態(tài)。1.Hechosesixstorybookstheotherday. Sixstorybooks____________byhimthe otherday.2.UncleLeegaveJackalargecakeforhe paintedthewallwonderfully.
