【生成·得】1.过去完成时的构成:_________。2.过去完成时的被动语态的构成:_____________。 
had been dne
【研学·析】一、过去完成时1.构成:had+过去分词2.用法(1)表示在过去某个时间或动作之前就已经发生的动作,通常简称为“过去的过去”。句中常有by,by the end f等介词(短语)和by the time,befre,when,until等引导的状语从句。The cncert had already begun when I gt there.我到那里的时候,音乐会已经开始了。By the end f last week,they had finished the wrk.到上周末为止,他们已经完成了工作。
(2)过去完成时表示发生在过去某个动作或时刻之前的动作一直延续到过去的另一个时间,常与fr,since等词连用。I had been at the bus stp fr 20 minutes befre a bus finally came.我在公交车站等了20分钟才来了一辆公交车。(3)过去完成时在几个重点句型中的应用①在n ,句型中,主句用过去完成时。I had n sner finished my hmewrk than the light went ut.我刚做完家庭作业,灯就灭了。He had hardly arrived when it began t snw.他刚到,天就开始下雪。
【点拨迷津】 hardly放句首,主句倒装吗?若把句型中的n sner,hardly提前放在句首,主句用部分倒装,即提前助动词had。Hardly had I gt hme when the rain pured dwn.我刚到家,大雨就倾盆而下。②在“It was the that...”句型中,that从句的谓语动词用过去完成时。It was the first time that I had seen the film.这是我第一次看那部电影。
③表示“意愿、打算”的动词如hpe,mean,want,think,expect,plan,intend等的过去完成时表示“原本……(但事实上并没有……)”之意。They had planned t see us ff at the airprt.他们本打算去机场给我们送行的。They had wanted t cme,but they were t busy.他们本来是要来的,但他们太忙了。
【内化·用】语法填空。①When he hurried t the statin,he fund the train _______(leave). ②By the end f yesterday, we ___________(receive) ver 1,000 letters frm all ver the wrld. 
had received
二、过去完成时的被动语态1.构成(1)肯定:主语+had been dne+其他成分;(2)否定:主语+had nt been dne+其他成分;(3)疑问:had+主语+been dne+其他成分;疑问词+had+主语+been dne+其他成分。
2.用法(1)表示过去某一时间以前已经完成的动作,常与by,befre等引导的时间状语连用。By the time he gt t schl,the first class had been finished.当他赶到学校的时候,第一节课已经上完了。The classrm had been cleaned befre the teacher came.在老师到来之前,教室已经被打扫干净了。Hw many buildings had been destryed when the hurricane ended?飓风结束的时候,有多少座建筑已经被毁了?
(2)在tld,said,knew,heard,thught等动词之后的宾语从句中,若表示过去某一被动动作时,用过去完成时的被动语态。He heard that the tickets had already been sld ut.他听说票已售完。The media reprted that mre than 1,000 peple had been killed in the hurricane.媒体报道,已有一千多人在飓风中丧生。
(3)根据语意可以判断出动作先后的被动语态,先发生的被动动作用过去完成时的被动语态。As the assignment had been dne,he went n t search fr sme infrmatin n the Internet.因为作业已经完成,他上网查阅了一些资料。He did what he had been tld t.他是按要求做的。

【文章大意】这是一篇说明文。文章主要讲述了很长一段时间以来,蝙蝠一直被认为是动物界最可怕的生物之一,但其实蝙蝠在保持生态系统平衡方面发挥着重要作用。1.【解析】have been。考查时态。句意:很长一段时间以来,蝙蝠一直是动物界最可怕的生物之一。根据前面的时间状语“Fr a lng time”以及句意可知,此处应用现在完成时表示从过去以来一直持续的情况。故填have been。2.【解析】related。考查固定短语。be related t是固定短语,意为“与……有关”。故填related。3.【解析】dangerus。考查形容词。此处应用形容词修饰后面的名词disease vectr。故填dangerus。
4.【解析】that。考查表语从句。be动词后是表语从句, that引导表语从句不作成分,只起连接作用,the fact is that意为“事实是……”。故填that。5.【解析】having。考查动名词。分析句子可知,空格前的介词f后面接动名词。故填having。6.【解析】the。考查冠词。the size f是固定短语,意为“……的尺寸”。故填the。7.【解析】additin。考查名词。根据前面的形容词essential可知,此处应用名词形式。故填additin。
