unit4现在进行时被动语态

必修二 unit4语法突破目标： 现在进行时态的被动语态 一、现在进行时态的被动语态的基本结构的构成：1现在进行时态的被动语态的肯定式为：am/is/are + being + done。 如： The question is being discussed at the meeting now. 这个问题现在正在会上被讨论。 Another bridge is being built over the Changjiang River at present. 目前长江上正在建造另一座大桥。2现在进行时态的被动语态的否定式为：am/is/are + not + being + done。如： The baby isnt being taken good care of. 这婴儿没在得到很好的照顾。 The animals are not being set free at present. 目前这些动物还不能被放出。3现在进行时态的被动语态的一般疑问句需将am/is/are 提到主语的前面。 -Is a new library being put up in their school now？ -Yes, it is. 甲：他们学校现在正在建一座新图书馆吗。乙：是，正在建一座新图书馆 -Are a number of Dongfeng trucks being shipped abroad? -No, they arent. 甲：一批东风卡车正被运往国外吗？乙：不，没有。4现在进行时态的被动语态的特殊疑问句为：疑问词 + am/is/are + (主语) + being + done。如：What is being done to the machine? 现在对这台机器要采取什么措施？ How many houses are being built in the village? 村里正在建造多少房屋？ When is the sports meeting being held in our school. 我校将在什么时候举行运动会？二、现在进行时态的被动语态的用法： 1现在进行时态的被动语态的同它的主动语态一样，表示现在正在进行的被动动作。 He is being interviewed by our headmaster now. 他正在接受我们校长的采访。 This film is being shown now. 这部电影正在被放映。2现在进行时态的被动语态的同它的主动语态一样，表示现阶段正在进行的被动动作。 The disease is being studied by scientists. 科学家们正在研究这种疾病。 These animals are being hunted at such a speed that they will disappear soon. 以如此速度捕杀动物，他们很快就会消失。 在进行时被动语态五个提醒 一. 不可遗漏being现在进行时的被动语态表示说话时主语正在承受谓语动词的动作，谓语动词的形式为“is/are/ambeing过去分词”。如果我们把being漏掉，就成为一般现在时被动语态或系表结构。试比较下列句子：Look！The children are being taken care of by their aunt. 瞧！孩子们现在正由姑母照看着。Children are taken good care of at school.? 孩子们在校被照看得很好。（指通常情况）The report is being written by one of the best students.? 报告正在由一个最好的学生写着呢。The report is well written. 报告写得很好。（系表结构）二. 表示现阶段现在进行时被动语态也可以表示目前这一阶段主语正在承受谓语动词的动作。Many interesting experiments are being carried out these days. 最近正在进行许多有趣的实验。（说话时，并不一定在进行）三. 表示计划或安排现在进行时被动语态还可表示按计划、安排主语将要承受谓语动词的动作（仅限于bring，take，send，hold，sing，show，play等表示移动的或能用来表示某项活动的少数及物动词）。A folk song is being sung next.? 下面将演唱一首民间歌曲。A party is being held tonight.? 今晚将要举行一场晚会。四. 没有进行时被动语态contain，include，impress，feel，want，like，love，satisfy，surprise，own等一些表示状态、 心理活动、拥有等意义的动词（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。Xiao Wang, come here. You are wanted on the phone. ?小王，过来，有人打电话找你呢。Football is becoming more and more popular. In other words, it is loved by more and more people.? 足球现在越来越流行了，换句话说，它被越来越多的人喜爱。五. 其它形式表示被动结构“beunder/in等介词名词”结构可代替进行时被动语态。The city is under attack（is being attacked）at the moment.? 目前这个城市正受到进攻。The telephone is in use（is being used）now.? 电话正在使用中。练习题1.
