[自主发现]：A.以上几句中的时态和语态是现在完成时的被动语态。B.以上几句中第①②句是该时态的肯定句式；第③句是一般疑问句式；第④句是否定句式。(2)语法知识归纳：

一、谓语现在完成时被动语态的构成：肯定式:主语＋have/hasbeendone...否定式:主语＋have/hasnotbeendone...一般疑问式:Have/Has＋主语＋beendone...？特殊疑问式:

疑问词＋have/has＋主语＋beendone...？Mikehasbeenselectedtotakepartinthefootballmatch.迈克已被挑选出来参加这场足球赛。

Thebridgehasnotbeencompletedyet.

大桥还没完工。

Hasthedateforthenextmeetingbeendecided?

下次会议的日期已决定了吗？[即时演练1]①Sofarmuchofmyhomework________(finish)already.(语法填空)②Manyoldhouses________(pull)downinthepastyears.(语法填空)③Greatchangeshavebeentakenplaceinmyhometown.(改错)二、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。Mycarhasalreadybeenrepaired.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for或since引导的时间状语连用，或用于“Howlong...？”句型中。Suchquestionshavebeendiscussedfornearlytwohours.

这样的问题已被讨论近两个小时了。Howlonghasthisroadbeenbuilt?这条大路已经修建多长时间了？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。Youshouldn'tleaveschoolbeforeyourhomeworkhasbeenfinished.在你的作业没完成之前你不应该离开学校。[即时演练2]

(1)用现在完成时的被动语态改写句子①Jack'sbosshasalwayspraisedhimforhisdevotiontowork.②Theyhavefoundagoodplacetobuildatempleinthevillage.③Wehaven'tyetdecidedhowtosolvethatdifficulttechnologicalproblem.

(2)补全句子①Iwillgohomewhenmyhomework___________.当我的家庭作业完成时我就回家。②Papermoney__________formorethanonethousandyears.

纸币已被使用了1,000多年了。三、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。Hisbosshasalreadypunishedhim.→Hehasalreadybeenpunished(byhisboss)．2．带有双宾语的动词，如give,send,bring,take,teach,show,tell,make,sing,write,read,sell,buy,pay,lend,pass,promise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。Thecompanyhasgivenhimachancetoworkabroadrecently.

→Hehasbeengivenachancetoworkabroadrecently(bythecompany)．→Achancetoworkabroadhasbeengiventohimrecently(bythecompany)．[即时演练3]
