【我的领悟】1．现在完成时的主动形式为“have/has dne”，强调过去的动作对现在的影响或结果。比如句(2), 句(4)。2．现在完成时的被动构成为“have/has been dne”，也是强调过去的动作对现在造成的影响或结果。如句(1)，句(3)，句(5)。
□现在完成时的被动语态一、现在完成时的被动语态的结构
The ink has nt been remved frm his vercat.墨迹还没有从他外套上去掉。Has the date fr the next meeting been decided?下次会议的日期已确定了吗？Hw lng has the battery nt been changed?电池多久没有更换了？He has been selected t take part in the sprts meeting.他已被挑选出来参加运动会。
二、现在完成时的被动语态的用法1．现在完成时的被动语态同它的主动语态一样，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 machine has already been repaired.机器已经修好了。
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。Hw lng has this film been shwn?这部电影已放映多长时间了？Financial prblems f the cmpany have been discussed fr nearly tw hurs.公司的财务问题已被讨论了近两个小时了。
※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 leave schl befre yur hmewrk has been finished.在你的作业没完成之前你不应该离开学校。
三、现在完成时的时间状语常与现在完成时连用的时间状语有：already(已经); yet(已经); recently/lately(最近); since then(从那时起); ever since (自那以来); ever (曾经); s far(迄今为止) ; by nw(到现在为止); fr a lng time (很长一段时间); in recent years (在最近几年里); in/during/ver the past/last years(在过去的几年里)
【归纳拓展】(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。His bss has already punished him.→He has already been punished (by his bss)．
(2)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，在变为被动语态时，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。He gave the little girl an apple.→The little girl was given an apple (by him)．→An apple was given t the little girl (by him)．
