当把现在进行时的主动语态的句子变为被动语态时,往往在be动词后加上一个being来体现现在进行时,然后再把动词的现在分词形式变成过去分词来表示被动,即:
be(am/is/are)+being+done。
一、现在进行时的被动语态的基本结构
肯定结构
be(am/is/are)beingdone
否定结构
be(am/is/are)+not+beingdone
一般疑问结构
be(am/is/are)+主语+beingdone
特殊疑问结构
特殊疑问词+be(am/is/are)+主语+beingdone
☛Anewlibraryisbeingbuiltnow.一座新图书馆正在被修建。
☛Someanimalsarenotbeingprotectedwellenough.有些动物没有受到足够好的保护。
☛Isthebridgebeingrepairednow?
现在那座桥在修吗?
☛Whatisbeingdoneonthenewmedicine?
正在这种新药物上做什么?
☛Howmanybridgesarebeingbuiltinthetown?
在这个镇里在建的桥有多少?
【思维延伸】
主动语态变被动语态的原则:
"三变":
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,原句主谓宾以外的成分不变。
☛Theyarebuildingnineparks.
→Nineparksarebeingbuilt.
→Howmanyparksarebeingbuilt?
二、现在进行时的被动语态的基本用法
1.表示正在进行或发生的被动动作,常与now,look等词连用。
2.表示现阶段或目前这段时间正在进行的被动动作,但这一被动动作在此时不一定正在发生。
3.表示按计划、安排主语将要承受某个动作。
4.表示一种经常性或习惯性的被动行为,常与always,forever,continually,constantly等词连用,往往带有赞扬、责备、厌烦及埋怨等感情色彩。
☛Thelifeofthepandaisbeingstudiedatpresent.现在正在研究大熊猫的生活。
☛Somerockmusicisbeingplayedbythemnext.下面将由他们演奏一些摇滚音乐。
☛Tomisalwaysbeingpraisedbytheteacher.汤姆总是受到老师的表扬。
三、使用现在进行时的被动语态应注意的问题
1.在现在进行时的被动语态中,be(am/is/are)和being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:
☛Thereportisbeingwrittenbyoneofthebeststudents.报告正在由一名最好的学生写着。
☛Thereportiswellwritten.这个报告写得很好。
(系表结构)
☛Mycomputerisbeingrepairednow.我的电脑现在正在被修理。
(强调正在被进行)
2.像takecareof,lookafter,talkabout,thinkof等动词与介词构成的短语用于现在进行时的被动语态时,其中的介词不可省略。
☛Somethingisbeingtalkedaboutamongthosepeople.在那些人中正谈论着某件事情。
3."be(am/is/are)+under/in+n."有时可相当于现在进行时的被动语态。
☛Theschoolisstillunderconstructionnow.=Theschoolisbeingbuiltnow.学校现在正在建设中。
☛Thenewlawisinuse.=Thenewlawisbeingused.这项新法律正被使用。
4.有些动词进行时的主动形式就可以表示被动的意思,常见的有print,cook,fry,bake,burn,hang等。
☛Thehouseisburning.房子着火了。
☛Themeatiscooking.正在煮肉。
5.有些表"状态、心理活动、情感"等的动词常用一般现在时的被动语态表示"正在进行"。
☛Youarewantedonthephone.有人打电话找你。
☛MP3isbecomingmoreandmorepopular.Inotherwords,itislovedbymoreandmorepeople.MP3越来越受欢迎,换句话说,它越来越受人们的喜爱。
6.非延续性动词、表示存在意义、所属关系、静态特征的动词以及系动词不用于现在进行时的被动语态。
☛It’swellknownthattheDiaoyuIslandsbelongtoChina.众所周知,钓鱼岛属于中国。
