謂語動詞的語態(tài)表示句子的主語和謂語動作之間的關(guān)系。（1）當(dāng)句子的主語是謂語動作的執(zhí)行者時，主、謂之間的關(guān)系稱為主動語態(tài)；（2）當(dāng)句子的主語是謂語動作的承受者時，主、謂之間的關(guān)系稱為被動語態(tài)。例如：

HeteachesusEnglish.

（主動語態(tài)）他教我們英語。

OurEnglishistaughtbyhim.

（被動語態(tài)）我們的英語是由他教的。

HespeaksEnglish.

（主動語態(tài)）他說英文。

Englishisspokeninmanycountriesallovertheworld.

（被動語態(tài)）世界許多國家都講英語。

在被動語態(tài)的句子中，謂語部分的結(jié)構(gòu)是be+過去分詞。被動語態(tài)的句子有時態(tài)的變化，這個變化反映在be動詞上。也就是說，把一個句子做成被動語態(tài)的句子，只需要寫出be動詞的所需時態(tài)，再加上所給動詞的過去分詞就行了。當(dāng)然，這只是指謂語部分而言。我們知道，be動詞作為一個獨(dú)立的謂語動詞有自己現(xiàn)在分詞（being）和過去分詞（been）。那么，下面我們來看看be在各種時態(tài)中的變化形式：被動語態(tài)的結(jié)構(gòu)主動語態(tài)被動語態(tài)被動語態(tài)否定式一般現(xiàn)在時ItellIamtoldIamnottold一般過去時ItoldIwastoldIwasnottold一般將來時IwilltellIwillbetoldIwon’tbetold現(xiàn)在進(jìn)行時I’mtellingIambeingtoldIamnotbeingtold現(xiàn)在完成時IhavetoldIhavebeentoldIhaven’tbeentold例如：

5.Thebuildinghasbeenbuiltforthreeyears.6.Thedishescanbewashedinhalfanhour.7.Mycarisbeingrepaired.Englishisspokeninmanycountriesallovertheworld.（一般現(xiàn)在時）世界上許多國家都講英文。

SomeTVsetsforsaleinthedepartmentstorewerestolenlastnight.（一般過去時）那家商場用來出售的部分電視機(jī)昨晚被盜。

Hewon'tbeallowedtomarryLarrabyhisfather.（一般將來時）他父親不會讓他娶拉拉為妻的。

Theywouldbesenttothearmywhentheyfinishedthetraining.（過去將來時）他們結(jié)束訓(xùn)練時將被派往部隊(duì)。

Theprojectisbeingcarried

out.（現(xiàn)在進(jìn)行時）這個計(jì)劃正在執(zhí)行中。

Thecasewasbeinginvestigatedthen.（過去進(jìn)行時）那時這案子正在調(diào)查中。

Thisnovelhasbeentranslatedintoseverallanguages.

（現(xiàn)在完成時）這本小說已被譯成了幾種語言。

Theysaidthatproductioncostshadbeenreduced.

（過去完成時）他們說生產(chǎn)成本已經(jīng)下降了。一般來說，在我們?nèi)粘Ｉ钪?，能用主動語態(tài)的時候就盡量不去用被動語態(tài)。只有在下列情況中我們才用被動語態(tài)：(1)不清楚動作的執(zhí)行者是誰,例如:

Thefrontwindowintheclassroomwasbrokenyesterday.

昨天，教室的前窗被打破了。(2)說話人對賓語的興趣大于對主語的興趣（這時可用by引導(dǎo)出動作的執(zhí)行者），例如：

MyTVsetisbeingrepairedintheshop.

我的電視機(jī)正在這店里修。(3)出于修辭的原因，或是說為了更好地安排句子。幾種特殊的被動結(jié)構(gòu)(1)關(guān)于帶情態(tài)動詞的被動結(jié)構(gòu)

帶情態(tài)動詞的被動結(jié)構(gòu)的固定句式為“情態(tài)動詞+be+過去分詞”。例如：Thedebtmustbepaidoffbeforenextmonth.那筆債務(wù)必須在下個月前付清。Oilcanbeturnedintoenergybyburningit.

油經(jīng)過燃燒可變?yōu)槟茉础?2)關(guān)于帶有兩個賓語的主動態(tài)變成被動態(tài)

我們先來看看“帶有兩個賓語的主動態(tài)句子的結(jié)構(gòu)”，重點(diǎn)看謂語部分：

Shesentmeanovelonmybirthday.

主謂間接賓語直接賓語狀語

Iallowedhimanhourtofinishthework.

主謂間接賓語直接賓語狀語Shesentmeanovelonmybirthday.(主動)

Iwassentanovelonmybirthday.(被動)

Anovelwassenttomeonmybirthday.(被動)

Mybrotherboughtmeawatchyesterday.(主動)

Iwasboughtawatchyesterday.(被動)

Awatchwasboughtformebymybrotheryesterday.(被動)幾種特殊的被動結(jié)構(gòu)(3)關(guān)于帶有復(fù)合賓語的主動態(tài)變成被動態(tài)

如果將帶有復(fù)合賓語（既：賓語+賓語補(bǔ)足語）的主動態(tài)的句子變成被動態(tài)的句子，我們只能選擇原來句子的賓語作被動態(tài)句子的主語．例如：

Thestorymadeuslaugh.

Weweremadetolaughbythestory.

Theyaskedmetohelpthem.Iwasaskedtohelpthem.Wesawthemcomingover.

Theywereseencomingover.幾種特殊的被動結(jié)構(gòu)鞏固練習(xí)()1ThePeople'sRepublicofChina___onOctober1,1949.

主動語態(tài)改被動語態(tài)的原則1.主動句=主語

+及物動詞

+賓語被動句=主語

+be+p.p.+by

賓語e.g.HelovesherSheislovedbyhim.Marywrotetwoletters.TwoletterswerewrittenbyMary.

主動語態(tài)改被動語態(tài)步驟如下：（1）主動句的賓語變成被動句的主語。（如為代詞改為主格）（2）將主動句的動詞改為be+p.p

。被動句的be動詞時態(tài)同于及物動詞的時態(tài)，be動詞的人稱、數(shù)同于被動句的人稱、數(shù)。（3）主動句的主語，置于by之后。（如為代詞改為賓格）

被動語態(tài)的句型：(1)肯定句

Theroomiscleanedbyuseveryday.(2)否定句

Theroomisnotcleanedbyuseveryday.(3)疑問句Istheroomcleanedeveryday?(4)特殊疑問句

Whatisthedressmadeof?III.幾種特殊類型的被動句：“S+V.+O1+O2”的被動語態(tài)：

Myhusbandgavemearing.Iwasgivenaringbymyhusband.Aringwasgiventomebymyhusband.2.含“感官或使役動詞”的被動語態(tài)：主語+beseenheard+todofeltmade

Isawhimentertheroom.=Hewasseentoentertheroom.Imadehimgo.=Hewasmadetogo(byme).3.帶補(bǔ)足語句子的被動語態(tài)：TheycallhimBob.=HeiscalledBob(byhim).4.不及物動詞+介詞=及物動詞的被動語態(tài)：Marylaughedatme.=IwaslaughedatbyMary.Shetookcareofthechildren.=Thechildrenweretookcareofbyher.1.Peoplehaveputbackpartsofstatuestogether.Partsofstatueshavebeenputbacktogether.Practice:changethefollowingsentencesinpassivevoice.2.Peoplehavereplacedthemissingpieces.Themissingpieceshavebeenreplaced.3.Hehasinvitedthefamousscientisttogiveaspeech.
