(2)The task can be finished in a week.6.带有不定式的被动语态结构：to be+过去分词。例如： (1) A new hotel is going to be built here. (2)He didnt want to be examined.7.短语动词是一个不可分割的整体，在变为被动语态时，不可漏掉组成短

5、语的介词或副词。例如：(1) The experiment has been carried out. (2) The old man is well taken care of.三、被动语态的疑难问题：1.主动语态变为被动语态的方法： (1)把主动语态的宾语变为被动语态的主语。 例如：1) She wrote the letter. The letter was written by her.2) He will water the flowers in the afternoon. The flowers will be watered .(2)主动谓语转换成被动语态：be 动词要按新主语

7、。在变为被动语态时，通常把间接宾语（即代表人的宾语）变为被动语态的主语，但也可以把直接宾语（即代表人物的宾语）变为被动语态的主语。例如：1) She asked him some questions. He was asked some questions by her. Some questions were asked him by her.2) Mother bought me a new coat. I was bought a new coat by mother. A new coat was bought for me by mother.3.被动语态中的by短语和with短语:

The tiger was killed with a gun.4.smell sweet 结构：英语中有些动词，用主动语态形式表示被动语态意义，如连系动词feel, look, taste, smell, sound, prove等；当wash, cu

The car drives fast. 2) The door wont shut.这门关不上。（主语的情况、属性，表示“门出问题了”） The door wont be shut.这门不用关上。（表示“不用关，不必关”，门无问题） The sentence reads clea

10、rly. The sentence is read clearly.5.“be+过去分词”结构有时并不是被动语态：某些动词，如等后的过去分词实际上已转化为形容词，作表语，表示状态、情绪等。例如：1) He was surprised at the news. The book is well written.2) The road was mended.
