时态是极具英语特色的一种动词形态,时态是表示行为、动作、状态在各种时间条件下的动词形式,下面是小编收集整理的英语时态之过去完成时,大家一起来看看吧!英语时态之过去完成时:过去完成时的否定句句型:主语 + had + not + 过去分词...过去完成时的否定句是在助动词had后加not,之后是过去分词:At that time we hadn"t met her.那时我们还没有见到她。The country had not yet recovered from the effects of the war.这个国家尚未从战争的影响下复原。过去完成时的疑问句一般疑问句句型:Had + 主语 + 过去分词...?回答方式:Yes,主语 + had.No,主语 + had + not.过去完成时的疑问句是将助动词had置于主语之前(大写had的第一个字母),在句尾加问号;这种语序是倒装语序:I visited the museum yesterday.—Had you visited it before? —Yes,I had./No,I hadn"t.昨天我参观了这个博物馆。——你以前参观过这个博物馆吗? ——是,我去过。/没有,我以前没有去过。过去完成时的被动语态:1、表示过去某一时间以前已经完成的动作,常与by, before等引导的时间状语连用。By the time he got to the school, the first class had been finished.The classroom hadn"t been cleaned before the teacher came.How many buildings had been destroyed when the earthquake ended?2、根据语意可以判断出动作先后的被动语态,用过去完成时。As the assignment had been done, he went on to search the Internet.He did what he had been told to另:当从句由after,before,when或 as soon as引导时,主句和从句都可以用一般过去时。When he arrived, he called her.They locked the door before they left.3、在told, said, knew, heard, thought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。They said the production costs had been reduced.The girl was reminded that his homework had not been handed in.The media reported more than 1,000 people had been killed in the earthquake.过去完成时与一般过去时的区别:虽然这两种时态都表示过去发生的动作或存在的状态,但在使用时应注意以下几点:1. 时间状语不同:过去完成时在时间上强调“过去的过去”;而一般过去时只强调过去某一特定的时间。比较:They had arrived at the station by ten yesterday.They arrived at the station at ten yesterday.2. 在没有明确的过去时间状语作标志时,谓语动词动作发生的时间先后须依据上下文来判断:先发生的用过去完成时,后发生的则用一般过去时。She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition.3. 当两个或两个以上接连发生的动作用and 或but 连接时,按时间顺序,只需用一般过去时来代替过去完成时;另外,在before ,after ,as soon as 引导的从句中,由于这些连词本身已经表示出时间的先后,因此也可以用过去时来代替过去完成时。He entered the room, turned on the light and read an evening paper.英语过去完成时测试练习题:1--What are Mr and Mrs Black doing ?---They _____ tea in the garden.A. are drinking B. drank C. have drunk D. drink2.
