byheraunt.3.Thediseaseisbeingstudied

atpresentbyscientist.基本用法：①

表示说话时正在进行的被动动作，句中常有now,rightnow,atthemoment,atpresent

等时间状语。②

表示现阶段正在进行的被动动作。(说话时不一定在进行)Theproblemoffoodsafetyisbeingstudied

byscientistsatpresent.③表示一种经常性的被动行为,常与always,constantly,frequently

等词连用,往往带有赞扬、羡慕、埋怨、讨厌等感情色彩。Childrenofourneighborsare

always

beingpraised

byourparents.④

与某些情态动词连用，表示对正在发生的动作的推测。Asaresultofstayinguplatetalkinglastnight,Jimmymaybebeingscoldedbyhisheadteacher.5.

注意要点(1)不可遗漏being。现在进行时的被动语态表示说话时正在进行的一个被动的动作，如果我们把being漏掉，即成为一般现在时的被动语态或系表结构。Look！Thechildrenarebeingtakencareofbytheiraunt.瞧！那些孩子正由他们的姑妈照看着。Childrenaretakengoodcareofatschool.孩子们在学校被照顾得很好。(一般现在时的被动语态)(2)现在进行时的被动语态也可以表示将来。A

folk

songisbeingsungnext.下面将唱一首民歌。

Apartyisbeingheldtonight.今晚将要举行一场晚会。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动作(此种用法仅限于少数及物动词,如:hold,take等)。(3)

“be＋under/in”等

“介词＋名词”

结构有时可相当于现在进行时的被动语态。
