使用现在完成时的被动语态要注意的问题1.现在完成时的被动语态、现在进行时的被动语态及一般过去时的被动语态的区别The machine has been repaired.（说明动作发生在过去，对现在有影响，“现在修好了”）The machine is being repaired nw.（说明动作正在进行）The machine was repaired yesterday.（只说明动作发生在过去）
2.非延续性动词，如brrw，finish，begin，start，buy，marry，pen，jin等构成的现在完成时的被动语态不能与表示一段时间的状语连用。若要表达相应的意思，则要改换动词或时态，例如：工程已开始三个月了。The prject has been started fr three mnths.（F）The prject has been n fr three mnths.（T）
1.用现在完成时的被动语态改写句子①Jack's bss has always praised him fr his devtin t wrk.Jack ___________________________ by his bss fr his devtin t wrk.②They have fund a gd place t build a temple in the village.A gd place t build a temple in the ___________________ village.③We haven't yet decided hw t slve that difficulttechnlgical prblem.Hw t slve that difficult technlgical prblem ___________________ yet.
带有双宾语的动词，如give，send，bring，take，teach，shw，tell，make，sing，write，read，sell，buy，pay，lend，pass，prmise等，变为被动语态时，一般将间接宾语变为被动语态的主语，若将直接宾语变为被动语态的主语时，间接宾语前面要用相应的介词。We have given him the bk.→He has been given the bk.→The bk has been given t him.
总 结1. 现在完成时的被动语态强调一个发生在过去的被动性的动作，动作已完成并强调对现在造成的影响或结果，主语和谓语之间为被动关系。The dr has already been lcked.门早已经被锁上了。I have been emplyed at the jb since 2015.自从2015年，我就做这份工作。
单句语法填空1. They ________________（sell）ten apartments in the past ne hur.2. He ________________（buy）a present when she visited Xinjiang.3. He ________ already ______________（ask）t help yu.4. The cmpany ________________ （make）its wrkers wrkhard recently.
