三、现在完成时的被动语态的用法 1． 表示被动的动作在说话之前已经完成， 强调过去的动作对现在造成的影 响或产生的结果 通常与 already，yet，never，recently 等副词及时间状语 so far，by now， up till now，before...等连用。 The work has already been finished. 工作已完成了。(结果是现在不用做这项工作了) The doctor hasn't been sent for yet. 还没有派人去请医生。(现在应派人去请医生)
2．表示一个被动的动作或状态开始于过去，持续到现在，并有可能持续下 去 常与 for 或 since 引导的时间状语连用，或用于 How long...？句型中。 The machine has been repaired for two hours. 这台机器已经修了两个小时了。(可能还会继续被修) 3．用在时间或条件等状语从句中，表示将来某时已完成的动作，即用现在 完成时的被动语态代替将来完成时的被动语态。 You can go home as soon as your task has been finished. 你的任务一完成就可以回家。
后自主感悟 1.例句 1，3 中的谓语是由“have＋been＋done”构成的现在完成时的被动语态的 肯定形式，强调过去的动作对现在造成的影响或产生的结果。 2．例句 2，4 中的谓语是由“have＋been＋done”构成的现在完成时的被动语态的 肯定形式，表示一个被动的动作开始于过去，持续到现在，并有可能持续下去。 3．例句 5 中的谓语是由“has＋not＋been＋done”构成的现在完成时的被动语态 的否定形式。
[语 法 精 要 点 拨]
一、现在完成时的被动语态的构成 have/has＋ been ＋过去分词 二、现在完成时的被动语态的常用句式 肯定式 否定式 一般疑问式 特殊疑问式 主语＋have/has been done... 主语＋have/has not been done... Have/Has＋主语＋been done...？ 疑问词＋have/has＋主语＋been done...？
2．非延续性动词 如 borrow，finish，begin，start，buy，marry，open，join 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。 The work was finished two weeks ago. 这项工作在两周前已经完成。 Th项工作已经完成。
[即时训练 2] 用所给动词的适当形式填空 ①In the last few years thousands of films have_been_produced (produce) all over the world. ②Though we don't know what was discussed，yet we can feel the topic has_been_changed (change)．
四、使用现在完成时的被动语态要注意以下几点 1．与一般过去时的被动语态的区别 一般过去时的被动语态所表示的动作或状态与现在的情况没有联系，而现 在完成时的被动语态则强调与现在的情况有联系。 The park was opened to the public last year. 去年这家公园向公众开放。(说明动作发生于过去) The park has been opened to the public. 这家公园已向公众开放。(说明动作发生于过去，但对现在有影响，即现在 公园已经开放了)
[即时训练 1] 根据要求变换句子 The children have already been told the good news. ①将上面的句子变为否定句。 The children haven't_been_told the good news yet. ②将上面的句子变为一般疑问句。 Have_the_children_been_told the good news yet? ③对上面的句子中的 the children 进行提问。 Who_has_been_told the good news yet?
3．短语动词 短语动词是一个不可分割的整体，在被动语态中要保持完整性，其中的介 词或副词不可省略。 It is said that the problem has been looked into. 据说已经调查了这个问题。 4．带有复合宾语的动词 变为被动语态时，只能将宾语变为主语，原来的宾补改为主语补足语。注 意：原来作宾补的省略 to 的不定式在被动语态中要用带 to 的不定式。 I have told them to help you. →They have been told to help you.
The city has been swept through by heat wave recently. 最近炎热横扫了这座城市。 His work has not been finished. 他的工作尚未完成。 Have the new booking systems for tickets been used? 新的订票制度已在使用中了吗？ How long has the battery not been changed? 电池多久没有更换了？
