第  PAGE 3 页 共  NUMPAGES 3 页 1. 构成 肯定式：am/ is / are + being done 否定式：am/ is/ are not + being done 疑问式：Am/ Is/ Are +主语+ being done? 2. 含义：表示“某人或某事正在被……”强调主语是动作的承受者，即主谓之间为被动关系。如： We’ve not moved in our new house as it is being painted now. 3. 用法 1）表示说话时正在进行的被动动作。 2）表示现阶段正在进行的被动动作，但动作不一定在此时此刻发生。如： A new railway station is being built. 3）表示一种习惯的被动行为，常带有赞赏、羡慕、讨厌等感情色彩，常与always, constantly 等次连用。如： He is always being praised by the teacher. 4）与某些情态动词连用，表示对正在发生的动作的推测。如： He may be being beaten by his father at the very moment. 4. 考点归纳 1）现在进行时的被动语态可表示根据计划或安排主语将要承受谓语动词表示的动作（仅限于及物动词）。如： A party is being held tonight. 2) 一些表状态、心理活动、拥有、存在的动词，如have, want, need, love, realize等，一般不用于进行时的被动语态，而常用一般现在时的被动语态表示此时此刻或目前主语正承受谓语动词表示的动作。 Wang Li, come here. You’re wanted on the phone. 3) 少数动词用于进行时态，用主动形式表示被动含义，如print, cook, fry, hang, build, make等，如：The meat is cooking. 4) “介词in, on, under+名词”构成的介词短语常表被动，可代替进行时的被动语态。如： The city is under attack (is being attacked) at the moment. The telephone is in use (is being used) now. The bridge is under repair/ construction (is being repaired/ constructed). 5) 现在进行时的被动语态与现在分词的被动式being done均可表示此刻正在进行的被动动作，可进行句型转换。如： Please tell me something about the meeting that is being held now. =Please tell me something about the meeting being held now. 5. 拓展 被动语态的构成为：be + 过去分词，be的不同形式表达不同的时态。 1）一般现在时：am/ is/ are + p.p. 2）一般过去时：was/ were + p.p. 3）现在进行时：am/ is/ are being + p.p. 4）过去进行时：was/ were being + p.p. 5）现在完成时：have/ has been + p.p. 6）过去完成时：had been + p.p. 7）一般将来时：will/ shall be +p.p.或 am/ is/ are/ going to be + p.p. 8）过去将来时：would be + p.p. 或 was/ were going to be + p.p. 6. 非谓语动词的被动形式的被动意义 to be done 不定式的被动，表将来和被动 to have been done 不定式完成式的被动，表完成和被动 being done 现在分词的被动，表进行和被动 having been done现在分词完成式的被动，表完成和被动,不作定语、补足语 done 过去分词，表完成和被动，作定语、状语、补足语。 当堂达标 1．________two tickets for the new play at the Grand Theatre on Saturday.
