  • 被动语态结构是be +过去分词,所以,各种时态的变化都是对 be 进行的,如:

    一般过去时:did变成:was done

    过去进行时: was/were doing----- was/were being done

    过去完成时: had done---- had been done

    一般现在时、do---- am/is /are done(

    现在进行时、am /is /are doing ------ am/ is /are being done

    现在完成时、have done-----have been done

    一般将来时、will do ---will be done/// am/is /are going to do--- am/ is /are going to be done

    将来完成时,will have done---- will have been done

    过去将来时 would do ----would be done ///was /were going to do-- was/were going to be done
