【归纳填空】答案: have/has(nt) been dne; 已经完成的被动动作
【语法精讲】一、现在完成时被动语态的构成
*At just this mment, the festive lanterns have been lit, and family members gather fr reunin. 此时此刻, 华灯初上, 万家团圆。*Have all f the stadiums fr the 2024 Paris Olympic Games been finished? 2024年巴黎奥运会的所有场馆竣工了吗? *Why has he been praised by his teacher? 为什么他被老师表扬了?
二、现在完成时被动语态的用法1. 现在完成时的被动语态, 强调过去的动作对现在造成的影响或结果, 通常与already, yet, just, never, recently等副词连用。*The sng Baby Shark has already been played 7. 04 billin times n YuTube. 《宝贝鲨鱼》这首歌曲已经在YuTube上被播放了70. 4亿次。2. 表示一个被动的动作或状态开始于过去, 持续到现在, 并可能持续下去, 常与fr或since引导的时间状语连用, 或用于“Hw lng . . . ? ”句型中。*Althugh paid leave has been included in the cuntry ’s labr law fr mre than 20 years, few wrkers culd enjy it. 尽管带薪休假被纳入国家劳动法已有20多年, 但是落实率并不高。
3. 用在时间或条件状语从句中, 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。*Yu shuldn ’t g ut befre yur hmewrk has been finished. 在你的作业完成之前你不应该出去。
【知识延伸】现在完成时的被动语态与一般过去时的被动语态的区别。一般过去时的被动语态表示的是一个被动的动作发生在过去某个时候, 它的结果对现在没有影响; 而现在完成时的被动语态, 动作或状态尽管发生在过去, 但强调这个动作或状态对现在造成的影响和结果。*The huse was built last year. 这个房子是去年建造的。*The huse has been built. We can mve in. 这个房子已经建好了。我们可以搬进去。

have been destryed
三、几点注意事项1. 只带有一个宾语的动词变为被动语态时, 将主动语态的宾语变为被动语态的主语。*As fr the epidemic, ur gvernment has taken a great many measures t cntain it. →As fr the epidemic, a great many measures have been taken by ur gvernment t cntain it. 对于这场疫情, 政府已经采取了很多措施来控制。
2. 带有双宾语的动词, 如give, send, bring, take, teach, shw, tell, buy, lend, 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。*Their teacher has given them many chances t practice what they have learned in class. →Many chances have been given t them t practice what they have learned in class(by their teacher). →They have been given many chances t practice what they have learned in class(by their teacher). 他们的老师给了他们很多机会练习上课所学(的内容)。
3. 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。*The wrk was finished tw weeks ag. 这项工作在两周前已经完成。
