Our homework has been finished by us.2. The Great Wall has been visited by many visitors.3.Two films have been seen by Mike since last month.4. These palaces have been turned into museums. 分析: A组强调动作的执行者,是主动语态, 结构:主谓宾, 相同点:两组都是完成时态, 结构: have/has+过去分词 B组的句子强调动作的承受者, 是被动语态. 相同点: 两组都是完成时态 结构: 助动词 have/has been +过去分词 Have/ has been V-ed现在完成时的被动语态表示到现在为止已经完成的某个被动的动作1.The new bridge over the Yellow River已经完成了_ 2.Many more buildings 已经被建_in the past ten years1.被动语态介词固定搭配不能省略。He has thought of a way of solving the problem.A way of solving the problem has been thought of2.break out/ happen/ take place/ arrive/ become/ die/ disappear etc 不及物动词没有被动语态Eg. The accident which happened yesterday surprised me.3.带双宾语的动词give /send/bring/ take/teach/show/ tell/ make/ sing/ write/ sell/buy/ ask/ pay/ borrow/ lend/ hand/ offer/provide/ past/get/promise 变被动语态有两种方法：Eg. I have given him the book1）=He has been given the book.2）=The book has been given to himHe has offered us the most comfortable service.主动语态表示被动的若干情形：1. 谓语动词用主动表被动的四种情形1）某些连系动词主动表被动：look, sound, smell, taste, prove, feelThis kind of cloth feels soft. My advice proved to be wrong.(2) 当open, close, shut, lock, move等用做不及物动词且表示主语的某种属性时，通常用主动形式表示被动意义。他们通常与cant, wont等连用。The door wont shut.Suddenly the door opened. (不强调谁开了门)3）当read, write, wash, sell, clean, cook, burn, draw, cut, wear等词与well, easily, quickly 等副词连用时，常用主动表被动。The cloth washes well. The poem reads smoothly. The book sells well. This cheese doesnt cut easily. Its too soft. This shirt will wear very long. The floor doesnt clean easily. This kind of rice cooks more quickly than that kind.但是别的时候要看具体情况而定：This book sells well. So far, 200 books have been sold out.The sentence was read clearly by her(4) 某些表示开始和结束的动作（begin, start, finish, end, etc.），当主语是事物且不强调动作的执行者时，可用主动表被动。When does the concert begin? The play ended at ten oclock.2.非谓语动词主动表被动的情况：（1）不定式to blame, to let用做表语时，通常用主动表被动。Who is to blame?(该怪谁呢？) The house is to let. (此屋出租。)（2）在“be +形容词+to do”结构中的不定式通常The question is difficult to answer. Do you think the water is safe to drink? (3) 不定式用于某些动词的（have, have got, get, want, need）宾语后做定语时：I have some letters to write. I want something to drink.但是注意：I have something to type.(我自己打) I have something to be typed. (请别人打)所以：当不定式的逻辑主语和句子的主语一致时就用主动表被动，若不一致，则需用被动表被动。I have a letter to post. (自己寄) I have a letter to be posted. (请别人寄)4）be worth doing; need / want / require doing (to be done)结构中In all, the book is worth reading. This might be worth thinking about. The plants want watering / to be watered every day. The wall wants repairing / to be repaired.但是：be worthy to be done / of being doneThis book is worthy to be read / of being read.三、应用部分（学生独立或小组合作完成、展示、评价） Change the following sentences into the present perfect passive voice.
