;语 境 自 主 领 悟;;一、现在进行时的被动语态的构成 be(am/is/are)＋being＋done The bridge is being built across the river this month. 这个月人们正在建横跨这条河的桥。;肯定句;It is reported that the water in the lake is not being protected now. 据报道，这个湖里的水现在没有得到保护。 Are the babies being taken care of by this nurse? 这些婴儿正由这个护士照看吗？ Who is being trained for the coming English speech contest? 为了即将举行的英语演讲比赛，谁正接受训练？;【即时训练1】句型转换 They are building a modern school in his hometown. ①A modern school ____________ in his hometown. (改为被动语态) ②A modern school _______________ in his hometown. (改为否定句) ③__________________________ in his hometown？(改为一般疑问句) ④________________________________? (对句中的 in his hometown 进行提问);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???at the moment 等时间状语。 A new film is being shown in the theatre. Let’s go to see it. 电影院里正在放映新电影呢，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。 —Could I use your car please? —Mine is being repaired by the workers. ——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。 I feel very puzzled that the goods in our shop are always being stolen. 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。 A party is being held tonight. 今晚将要举行一场晚会。 5. 与部分情态动词连用，表示对正在发生的动作的推测。 He may be being scolded by his father at the very moment. 此刻他也许正被他父亲责骂。;【即时训练2】用所给动词的适当形式填空 ①The little boy has made rapid progress recently and is always _____________(praise) by his teachers. ②The plan to explore the South Pole _____________(make) these days. ③The question about where is the factory going to be built _________________(discuss) at the moment.;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： The report is being written by the best student. 报告正在由一名最好的学生写着。 The report is well written. 这个报告写得很好。(系表结构);2. 不可遗漏介词 take care of，look after，talk about，think of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!
