　　I’ve been sitting in the garden.

　　2)过去完成进行时(由had been + ing分词构成): 过去某个时刻以前一直在进行的动作

　　3)将来完成进行时: 将来某个时刻以前一直在进行的动作.

　　By next summer, he will have been working here for twenty years.

　　In another month’s time she’ll have been studying here for three years.

　　4)将来完成时(由shall/will have + 过去分词构成): 将来某时会业已发生的事.

　　They’ll have hit the year’s target by the end of October.

　　语态

　　可以有两种被动结构的类型,例如:
