一、与be动词一起构成现在进行时的被动语态(am/ is/ are being done)和过去进行时的被动语态(was/ were being done)。如:The new houses are being painted.这些新房子还在刷漆。When I went to pay him a visit, he was being examined by a doctor. 当我去看他时,他正在接受医生的检查。二、作后置定语,修饰某一名词,表示某一被动动作正在进行。如:The meeting being held now is of great importance. 现在正在开的会很重要。上面的句子也可以变成含有定语从句的句子:The meeting which is being held now is of great importance.注意:being done,to be done与done均可作后置定语,其区别为:being done表示正在发生的被动动作;to be done表示将要发生的被动动作;而done表示已经发生的被动动作。如:The house to be built here next year belongs to Fred. 明年将在这里建的房屋是弗雷德的。The house built here last year belongs to Fred. 去年在这里建的房屋是弗雷德的。三、作某些及物动词或介词的宾语。如:John hates being laughed at in public. 约翰不喜欢当众被嘲笑。Do you mind being left alone at home. 把你一个人留在家里你介意吗?My class teacher was honoured for being devoted to the cause of the education. 我的班主任因致力于教育事业受到了表彰。四、有时作主语或用在see,hear,feel等少量感官动词后作宾语补足语。如:Being lost can be a terrifying experience.迷路可能是一种可怕的经历。(作主语)He heard the song being sung next door. 他听到隔壁有人在唱这首歌。(作宾补)
