由“助动词be + 动词的过去分词”构成。助动词be 有时态、人称和数的变化。(1) 一般现在时:am/is/are +过去分词。如:Rice is grown in south China. 华南种植水稻。(2) 一般过去时:was/were+过去分词。如:The glass was broken yesterday. 这块玻璃是昨天打烂的。(3) 现在进行时:am/is/are being +过去分词。如:The project is being carried out. 这个计划正在执行中。(4) 过去进行时:was/were/being +过去分词。如:This road was being built this time last year. 这条路去年这个时候还在修建。(5) 一般将来时:will be +过去分词。如:The cars will be sent abroad by sea. 这些汽车将由水路运往国外。(6) 过去将来时:would be +过去分词。如:The manager said the project would be completed by the end of the year. 经理说这个工程在年底前将会完成。(7) 现在完成时:have/has been +过去分词。如:This novel has been translated into several languages. 这本小说已被译成了几种语言。(8) 过去完在时:had been +过去分词。如:When I got to the theatre, I found the tickets had already been sold out. 我到达剧院时,发现票已卖完了。
1. 一般现在时 He cleans the blackboard.2.一般过去时 He cleaned the blackboard. 3.一般将来时 He will clean the blackboard.4.现在进行时 He is cleaning the blackboard. 5.过去进行时 He was cleaning the blackboard. 6.将来进行时 He will be cleaning the blackboard. 7.现在完成时 He has cleaned the blackboard. 8.过去完成时 表示过去两个动作的一前一后,所以一个动作不能形成过去完成时9.将来完成时 He will have cleaned the blackboard. 10.现在完成进行时 He has been cleaning the blackboard.11.过去完成进行时 表示过去某一时刻之前开始的动作或状态一直延续到过去某一时刻。需要两个动作,所以一个动作不能形成过去完成进行时。12.将来完成进行时 He will have been cleaning the blackboard.信我的吧!过去完成时和过去完成进行时一个动作不能形成。
