【我的领悟】1．现在进行时的被动语态肯定形式为： ________。如句(4)和句(5)。2．现在进行时的被动语态否定形式为： ________。如句(3)。3．现在进行时的被动语态的一般疑问句式为：________。如句(1)，句(6)和句(7)。4．现在进行时的被动语态的特殊疑问句式为：________。如句(2)。
Keys：1．主语＋am/is/are being dne.2．主语＋am/is/are nt being dne.3．Am/Is/Are＋主语＋being dne?4．疑问词＋am/is/are＋主语＋being dne?
□现在进行时的被动语态一、构成
Wait a minute, please.I am being examined by the dctr.请稍等。我正在接受医生的检查。The plan is nt being carried ut well.这个计划进展得不顺利。What is being talked abut by the students?学生们在谈论什么？Is the classrm being cleaned nw?教室此刻在被打扫吗？
二、用法1．表示说话时正在进行的被动动作。At present a new hme is being built fr pandas.目前正在为熊猫建一个新家。2．表示现阶段正在进行的被动动作，说话时不一定在进行。A new railway statin is being cnstructed.一个新的火车站正在建设中。
3．表示一种经常性的被动行为，常与always，cnstantly，frequently等表示频度的副词连用，带有赞赏或厌恶等感情色彩。I feel very surprised that the windw f ur classrm is frequently being brken.我感到非常吃惊的是，我们教室的那扇窗户经常被打破。
4．表示按计划或安排将要发生的被动动作(仅限于少数及物动词)。A ppular sng is being sung next.下面将唱一首流行歌曲。
三、注意事项1．一些表示状态、心理活动、拥有、存在等的动词，如 have，want，need，lve，realize等，一般不用于进行时，因而也没有进行时的被动语态，而常用一般现在时的被动语态表示此刻或目前主语正承受谓语动词表示的动作。玛丽，过来，有你的电话。Mary, cme here.Yu're being wanted n the phne.(错误)Mary, cme here.Yu're wanted n the phne.(正确)
2．少数动词用于现在进行时态，用主动形式表示被动含义，如 print，ck, fry，hang等。These magazines are printing.这些杂志正在印刷中。※3.“be＋in/n/under＋名词”常含被动意义，可代替现在进行时的被动语态。The castle is under attack (＝being attacked) at the mment.目前，那座城堡正受到进攻。
4．因为被动语态的基本结构为be dne，不少学生将现在进行时的被动语态结构“am/is/are＋being dne”误写成一般现在时的被动语态结构“am/is/are＋dne”。例如：瞧，这条道路正在建设。Lk! The rad is built.(错误)Lk! The rad is being built.(正确)晚宴正由克里斯蒂娜准备着。The dinner is prepared by Christina.(错误)The dinner is being prepared by Christina.(正确)
四、句型转换现在进行时的被动语态与现在分词的被动式being dne均可表示正在进行的被动动作，因此它们之间可以相互转换。我发现国旗正在升起。I find the natinal flag is being raised.＝I find the natinal flag being raised.(being raised作宾语补足语)※非谓语动词的被动形式，表达不同时间的被动意义，作用也不一样。
