Listen! )4).过去进行时：_55) .现在完成时:_（since+clause/ the past time, for + some time , so far, these days）6).过去完成时：_7).情态动词：_ 例如：He opened the door.他打开了门。(主动句：主动、主动、主去动。) The door was opened.门被打开了。(被动句：被动、被动、主被动。)思考：各种时态的被动语态的结构是什么?课内探究学案I. 思考一：各种时态的被动语态的结构 时态被动语态结构一般现在时am/is/are+Vp.p一般过去时was/were一般将来时will/be going to be 现在进行时am/ is/ are being过去进行时was/were being现在完成时have/ has been 过去完成时had been含有情态动词can / may / must / should beII. 思考二：怎样把一个句子由主动语态变为被动语态？Eg:Children often sing this song .-This song is often sung by children.(S + V+ O) All the people laughed at him.-He was laughed at by all people.(S + V+ O) 将含有介词或副词的动词短语变为被动结构时，不可将介词或副词去掉。 You ought to take it away.-It ought to be taken away.有些动词短语本身即是被动语态的形式, 不要再加by 短语,常用的有 be covered with 用.覆盖 be surprised at 对.感到惊奇 be interested in对.感兴趣 be worried about 对.担心 be made of/from 由.制成 be known to 出名歌诀是：宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。 情态动词变被动，情态加be加“过分”，原来带to要保留。【合作探究】（学困生必做）1.

The boy was made to work for him. I saw him fall off the tree.He was seen to fall of f the tree. make sb do sth-_ ask sb do sth-_ tell sb do sth-_ see sb do sth-_练习巩固：用所给动词的适当形式填空1.

It is said that 据说 It is reported that 据报道 It is thought that 大家认为 It is believed that有人相信3.复合句变被动，主从句都要变 Eg:If a computer is bought for me , the work will be finished more quickly.VI.思考六： 不用被动语态的动词：1. 不及物动词（vi.) 如: happen, take place, appear, disappear (正) An accident happened last night.(S+V) (误) An accident was happened last night.2. 连系动词（Link.v.) 如：be, look, seem, feel, sound, smell, taste, get, turn, become (正) The flowers smell sweet.(S+V+P) (误) The flowers are smelt sweet.3. 当此动词表示事物的自然属性的时候：The pen writes very fast.这支钢笔很流利。The womans clothes sell well. 女装卖的快。 小结：关于被动语态的几种用法你掌握了吗？【精讲点拨课后提升】一 单项选择1.
