1.表示现在正在进行的被动动作Mary

（interview）now.Mycar

（repair）now.Anewfilm

（show）inthetheater.Myhouse

（paint）now.isbeinginterviewedisbeingrepairedisbeingpaintedisbeingshown2.表示现阶段正在进行的被动动作，但此动作不一定在此时此刻发生Anewstation

bytheteachers.Totheteacher’sanger,thesillyquestions

byhisstudents.她最近进步很快，总是被老师表扬。让老师生气的是，学生总是问愚蠢的问题。3.（注意)现在进行时被动语态与always,constantly,allthetime等词连用时，表示经常性的被动动作，此时往往带有赞赏或厌恶等感情色彩。4.与部分情态动词连用，表示对正在发生的动作的推测。

He

byhisfatherattheverymoment.

他此时此刻可能正在被他的父亲殴打。isalwaysbeingpraisedarealwaysbeingaskedmaybebeingbeatenLook.Thechildren

(takecareof)bytheiraunt.(现在的情况）Children

(takecareof)atschool.(通常的情况）Thereport

(write)byoneofthebeststudents.这份报告是由一个最优秀的学生撰写的。Thereport

(write).(系表结构）这份报告写得很好。

现在进行时被动语态的“四注意”1.注意不可遗漏“being”,如果把being漏掉，就成为一般现在时的被动语态或系表结构。arebeingtakencareofaretakencareofisbeingwritten

iswellwrittenAfolksong

（sing）next.Aparty

(hold)tonight.Itissaidthataplane

(flow)byhimtoAmericaateightnextSunday.2.注意现在进行时的被动语态也可以表示将来。现在进行时的被动语态有时可表示按计划或安排将要进行的一个被动的动作(此种用法仅限于少数及物动词)。isbeingsungisbeingheldisbeingflownXiaoWang,comehere.You

（want）onthephone.小王来这,你需要通过电话取得联系。Footballisbecomingmoreandmorepopular.Inotherwords,it

(love)bymoreandmorepeople.足球正越来越受欢迎了。换句话说，越来越多的人喜欢它。3.注意没有现在进行时的被动语态的动词。一些表示“状态、心理活动、拥有、存在”等的动词,一般不用现在进行时的被动语态,而常用一般现在时的被动语态表示此时此刻或目前主语正承受谓语动词的动作。arewanted

isloved

Thecityisunderattack(=

)atthemoment.Theproblemisunderdiscussion(=

)atthemeeting.Thetelephoneisinuse(=

)now.4.“be+under/in等介词+名词”结构可表示现在进行时的被动语态的含义。(名词前一般不用冠词）isbeingattackedisbeingdiscussedisbeingused一.用以下单词的适当形式填空。1.Newfunctions_______________________(add)tothecameraatpresent.2.Manyspeeches_________________(hold)inourschoolthesedays.3.Idon’tknowwhattimeitisnow.Mywatch____________________(repair).4.Anewstadium___________________(build).Theyhopetofinishitnextmonth.5.---Doyoulikethematerial?--Yes,it____________(feel)verysoft.arebeingaddedarebeingheldisbeingrepairedisbeingbuiltfeels6.Thebridgewhich______________(build)lastyear____________(look)beautiful.7.Thecamerayou_______________(use)now______________(belong)tome.8.Onethirdoftheclass__________________________(question)bytheteachersnow.9.
