谓语变被动（时态不变）

be+being+done+by3.主动语态变被动语态的原则“三变”例：Theyarebuildingnineparks.原句主语变为by短语宾语变为主语谓语由主动变为被动“三不变”原句意思不变原句时态不变原句主谓宾以外成分不变Nineparks______________bythem.Howmanyparks____________?arebeingbuiltarebeingbuilt三、现在进行时的被动语态的用法1．表示此刻正被进行的动作，句中常用now，atthemoment等时间状语。Changjinhu

isbeingshowninthecinemanow.Let'sgotoseeit.现在《长津湖》正在电影院放映呢，咱们去看吧。2．表示现阶段正被进行的动作，但此动作在此时此刻不一定正在发生。—CouldIuseyourcarplease?—Mineisbeingrepairedbytheworkers.——我能用你的车吗？——我的车正在被工人们修着。3．表示一种经常性的被动行为，常和always，constantly，frequently等表示频率的副词连用，这种用法常常带有说话者的赞扬或厌恶的感情色彩。Ifeelverypuzzledthatthegoodsinourshoparealwaysbeingstolen.我感到很迷惑，我们商店的商品老是被偷。4．表示按计划或安排主语将要承受谓语动词所表示的动作。Awelcomepartyisbeingheldtonight.今晚将要举行一场欢迎晚会。5．与部分情态动词连用，表示对正在发生的动作的推测。Hemaybebeingscoldedbyhismoherattheverymoment.此刻他也许正被他妈妈责骂呢。isbeingdiscussedbeingpraisedisbeingmade13四、使用现在进行时的被动语态应注意的问题1．不可遗漏being现在进行时的被动语态中，be为第一助动词，being为第二助动词，缺一不可，且位置不可互换。此结构若缺少being，则就成为一般现在时的被动语态或系表结构。试比较：Thereportisbeingwrittenbyafamousprofessor.报告正在由一名著名的专家写着。Thereportiswellwritten.这个报告写得很好。(系表结构)2．不可遗漏介词takecareof，lookafter，talkabout，thinkof等动词短语用于现在进行时的被动语态时，其中的介词不可省略。Look！Thechildrenarebeingtakencareofbytheirgrandmother.瞧！那些孩子正由他们的奶奶照看着。3.没有进行时的被动语态一些表示状态、心理活动、拥有、存在等的动词(和主动语态一样)一般不用进行时被动语态,常用一般现在时被动语态表示此时此刻或目前主语承受谓语动词的动作。
