been

answered.(2)Shehasn'tbeentoldaboutityet.3.现在完成时被动语态的一般疑问句需将________提到主语的前面。(1)Hashisbikebeenrepaired?(2)Havetheybeennotifiedaboutit?4.特殊疑问句为：提问主语：提问其它：have/has特殊疑问词+have/has+been+v-ed？(1)Whohasbeeninvited?(2)Whyhashebeenpraisedbyhisteacher?特殊疑问词+一般疑问句？用法例解：1.主语是行为动作的承受者。TheTempleofZhangFeihasbeenrebuilt.2.说话时已经完成的动作或出现的结果。(1)Soeventheolivewreathhasbeenreplaced!(2)Thedoorhasbeenlocked.3.动作或状态始于过去，持续到现在，并可能

fit(适合),have(有),hold(容纳),lack(缺乏),own(占有),suit(适合),fail(失败),belongto(属于),agreewith(同意)等。e.g.(1)TaiwanbelongstoChina.(2)Thecoatcostme¥300.拓展：所有的及物动词都有被动语态？Thepatientshavebeentakengoodcare
